Hereinafter, the embodiments will be described in detail with reference to the drawings.

FIG. 2A is a configuration diagram of the continuously-variable transmission device according to the first embodiment of the present invention, and FIG.

2A, the continuously variable transmission according to the first embodiment includes a planetary gear train PGT, a motor GM, a control system CS, and a housing C. As shown in Fig.

The planetary gear train PGT includes a first planetary gear set PG1 having first, second and third rotary elements N1, N2 and N3 and fourth, fifth and sixth rotary elements N4 The rear gear RPG is constituted by a speed reducer RG and a second planetary gear set PG2. The rear gear RPG is constituted by a speed reducer RG and a second planetary gear set PG2 And includes four connection axes TM1, TM2, and TM3 (GMS) that always connect the respective rotation elements.

The components of the planetary gear set are arranged in this order from the engine side in the order of the first planetary gear set PG1, the speed reducer RG, and the second planetary gear set PG2.

The first planetary gear set PG1 is of the Two Suns-Two Planets (GS1) type and has a first carrier PC2 to which power is input (the third rotation element N3), a first carrier PC2 having the same axis The first and second sun gears S1 and S2 which are the elements N1 and N2 and the first and second sun gears S1 and S2 which are external to the first and second sun gears S1 and S2, 2 planetary gears P1 and P2, and the two planetary gears P1 and P2 are one body.

The gear ratio of the first planetary gear set PG1 satisfies P1 / S1? P2 / S2 and the power input to the first carrier PC1 is transmitted to the first and second sun gears S1 and S2 And the difference between the rotational speeds generated between the two sun gears S1 and S2 is regulated through the rear gear so that the two sun gears S1 and S2 are accelerated and decelerated And a continuously variable transmission is performed.

In configuring the rear gear RPG, the two connection axes TM1 and TM2 connected to the first planetary gear set PG1 must always rotate in the same direction, and the reduction ratio of the two shafts should be close to 1, The planetary gear unit is difficult to satisfy. Therefore, the above-mentioned condition is satisfied by combining the speed reducer RG and the second planetary gear set PG2.

The rear gear RPG has a difference in rotational speeds generated between the first and second sun gears S1 and S2 (first and second rotational elements N1 and N2) of the first planetary gear set PG2, To the sixth rotary element N6 of the rear gear RPG. That is, the decelerator RG and the second planetary gear set PG2 are combined to play a single role. It is difficult to explain the role of the reduction gear RG and the role of the second planetary gear set PG2. Therefore, the rear gear RPG will be described as a single planetary gear set, and only the elements for inputting and outputting power to the rear gear RPG are given rotational element names.

Shaft The reduction gear RG is of a parallel shaft type and includes a first gear G1 and a second gear G2 (which is a fifth rotary element N5) arranged on the same axis as the first carrier PC1, And a third gear G3 and a fourth gear G4 which are circumscribed by the first and second gears G1 and G2 and are one body.

The second planetary gear set PG2 is of the single pinion type SP and includes a third carrier PC3 (which is the fourth rotation element N4), a third carrier PC3 which is on the same axis as the third carrier PC3 A third planetary gear P3 meshing with the third sun gear S3 and a ring gear R in contact with the planetary gear P3.

The gear reducer RG of the parallel shaft type may use another type of speed reducer as one example for explaining the present invention. Therefore, the scope of the present invention should not be limited to a reduction gear of a parallel shaft type.

Referring to the connection between the four connection axes TM1, TM2, TM3, and GMS,

The first connection shaft TM1 normally connects the first rotary element N1 and the fourth rotary element N4 and the second connection shaft TM2 connects the second rotary element N2 and the fifth rotary element N2, And the third connecting shaft TM3 always connects the speed reducer RG and the second planetary gear set PG2 to each other and the control shaft GMS is connected to the sixth rotating element N6, Connect the control gear (GMG) or the motor (GM) at all times.

The power input to the third rotary element N3 is divided into first and second rotary elements N1 and N2 and the first and second rotary elements N1 and N2 are divided into a first and a second rotary elements N1 and N2, Is transmitted to the fourth and fifth rotary elements N4 and N5 of the rear gear RPG. A difference in rotational speed is generated between the two rotary elements N4 and N5, and the difference in the rotational speed is output to the sixth rotary element N6.

The difference in rotational speed between the first and second rotary elements N1 and N2 (the fourth and fifth rotary elements) is controlled by controlling the power output to the sixth rotary element by the motor, The second rotation elements N1 and N2 (the fourth and fifth rotation elements) are accelerated and decelerated to perform the continuously-variable shifting.

In an all-wheel drive vehicle, the output from the Ravigneur or Simpson planetary gear set is the farthest from the engine side, but the position of the differential should be close to the engine side. Therefore, the Ravigneaux automatic transmission undergoes a complicated process leading from the ring gear to the transporter drive gear to the idle gear to the transfer driven gear to the differential gear to overcome the above problems.

However, in the CVT, the rotation of all the rotating bodies except for the third rotating element N3 and the sixth rotating element N6 to which the power is input rotates in proportion to the driving shaft. Therefore, the gear G1 connected to the first, second and third connection axles TM1, TM2, TM3, the first, second and third connection axles TM1, TM2, One of the gears G2 and G3 and the gears G3 and G4 engaged with the gears G1 and G2 may be selected as the output member and used as the output element.

S2, TM2, G1, G2, G3, G4 and R are connected to each other or are interlocked with each other. Therefore, it is possible to select one of all the rotors capable of power output as an output element.

The motor GM is configured to perform the shifting by suppressing the rotation of the sixth rotating element N6 when the forward shift state is changed, thereby increasing the rotation of the sixth rotating element N6 in the reverse shifting state. Therefore, the motor (GM) must combine the functions of the generator and the motor.

Generally, the generator rotates at a high speed and power generation, while the sixth rotating element N6 rotates at a high torque of a low speed. Therefore, the output shaft of the motor (GM), which has to control the sixth rotating element N6, must also rotate at a high torque of low speed. Accordingly, the motor (GM) must include a speed reducer (RC), and its deceleration magnification is about 200 times at most.

The continuously variable transmission (CVT) is directly connected to the engine without a clutch. When the input power changes suddenly, such as engine startup, the sixth rotary element N6 corresponding to the sudden speed increase must be accelerated. However, the deceleration magnification of the motor GM is up to 200 times, which hinders the abrupt acceleration of the sixth rotating element N6 by its own inertia only. Therefore, the first clutch C1 that selectively disengages power between the sixth rotary element and the rotor of the motor until the motor GM rotates at an appropriate speed should be included.

When the motor GM includes the clutch C1, the clutch C1 is transmitted from the sixth rotary element N6 side in the order of the clutch C1, the speed reducer RC and the rotor or in the order of the speed reducer GC, the clutch C1, Respectively.

As a method of starting the engine equipped with the continuously-variable transmission (CVT), there are cases in which a starter motor is used and a motor (GM) mounted in the transmission is used, and in some cases, the types of clutches are different. One of the first clutch C1 and the third clutch C3 is used in the case of using the starter motor and the motor GM used in the continuously variable transmission CVT is used without using the starter motor Only the third clutch C3 is used.

For reference, the second clutch C2 is used for the hybrid vehicle, which will be described in the description of the hybrid vehicle.

The first clutch C1 is a drive clutch and is disposed between the sixth rotary element N6 and the rotor of the motor GM in a normal close type. The first clutch C1 is connected to the power input to the continuously- Thereby preventing transmission of the distorted driving force to the output shaft.

The third clutch C3 is a normally open type braking clutch, and the third clutch C3 is fixed to the output element so that the output element can not be rotated. That is, when the clutch is operated, only the output element is stopped so that the output element is installed between the element belonging to the selected group and the housing (H).

In addition, if there are output elements in TM1 and PC2, a clutch can be installed in one of them, and if there are output elements in TM2, TM3, G1, G2, G3, G4 and R, a clutch can be installed in one of them.

(Z, P1 / S1 x S2 / P2) between the first and second rotary elements N1 and N2 in setting the number of teeth of the gear of the first planetary gear set PG1 in the continuously-variable transmission CVT, The capacity and the capacity of the motor GM are influenced by the value of the first planetary gear set PG1 and the Z value is closer to 1 but the first gear L1 of the first planetary gearset PG1 and the second- (S2) and (P2) have the same inter-axis distance. Therefore, when the modules of the first and second gears are formed of the same module, the value of Z may be different from the expected value.

Therefore, Table 1 below is for finding a method for overcoming the Z value of the first planetary gear set PG1 when the Z value of the first planetary gear set PG1 is different from the expected value. In the first and second gears S1 and S2, (P2) are composed of the same module and different modules are constructed.

The same module Variant module Ten Column 1 Column 2 Column 1 Column 2 Gear S1 P1 S2 P2 S1 P1 S2 P2 Number of teeth 29 16 30 15 29 16 39 21 module 2 2 2 1.5 Axis distance 45 45 Z 1.103 1.024 T 17.8% 5.3%

The theoretical maximum torque of the continuously-variable transmission (CVT) is an input torque × 1 / | Z-1 |. Substituting the Z value of the variant module of Table 1 above, 1.024, produces a torque of 41.6 times the input torque (a large capacity motor is required for the torque), but in fact, such a large torque is not required in the automobile. Therefore, taking into account that the maximum speed ratio of the passenger car is usually 3 to 4, the maximum torque is generated when the reduction ratio is 3.33 in the present description, and the capacity of the motor is determined.

In Table 1, T represents the magnitude of the power output to the sixth rotational element N6 as a percentage relative to the input power when the speed ratio of the output shaft is 3.33, and a detailed description thereof will be described in detail in Table 3 and the following description have.

Referring to Table 1, when the number of teeth of the gear of the first planetary gear set PG1 is set to the same number of teeth of the same module in Table 1, Z value is 1.103 and T value is 17.8%. That is, 17.8% of the power is transferred to the sixth rotating element N6, and the capacity of the motor (GM) for controlling the motor is 17.8% or more.

However, if the number of teeth is the same as that of the deforming module in Table 1, the Z value is 1.024 and the T value is 5.3%. That is, 5.3% of the power is transferred to the sixth rotating element N6, and the capacity of the motor (GM) for controlling the motor is 5.3%.

Therefore, in setting the gear ratio of the first planetary gear set PG1, the continuously-variable transmission CVT may be configured such that the gear modules of the first-gear S1 and second- The gear modules of the first-gear S1 and second-gear S2 are configured as different differential modules, if the expected value is different from the expected value.

3 (a) is a block diagram showing a control system CS in a continuously variable transmission (CVT) according to an embodiment of the present invention.

Referring to FIG. 3A, the control system CS includes an operation information detector CS1 for detecting operation information for controlling the CVT, A control axis RPM calculating section CS2 for calculating the RPM, and a control section CS3 for controlling the transmission on the basis of the target RPM.

The operation information detection unit CS1 detects the operation state of the vehicle based on the vehicle speed sensor VSS, the control shaft RPM sensor CRS, the engine RPM sensor ERS, the accelerator pedal position sensor APS, the brake pedal position sensor BPS, Sensor (TPS), the speed of the vehicle through the VSS, the RPM of the control shaft (GMS) through the CRS, the engine RPM through the ERS, the pedal amount of the accelerator pedal via the APS, The pedal amount is detected and the shift position of the gear lever is detected through the TPS.

The driving information is divided into basic information and weight information. Information generated during operation such as the vehicle speed, the control RPM, the engine RPM, the amount of pedal of the accelerator pedal, the amount of the brake pedal and the position of the shift lever belong to basic information, There are external conditions such as weather, road conditions, traffic conditions, vehicle weight, engine aging, wheel specifications and so on.

The operation information detector CS1 detects the basic information and the weight information to provide the control axis RPM calculator CS2 and the controller CS3 at all times.

The control axis RPM calculating unit CS2 loads a target RPM map for setting a target RPM and a weight map for setting weights according to the detailed items of the operation information when the vehicle is shipped.

The control axis RPM calculating unit CS2 extracts a target RPM corresponding to at least one basic information in a predetermined target RPM map at the time of departure.

In addition, the control axis RPM calculating section CS2 extracts a weight value by linking at least one weight information in a weight map determined in advance at the time of departure.

In addition, the control axis RPM calculating section CS2 reflects the weight to the extracted target RPM to present the corrected target RPM.

The control unit CS3 controls the motors GM and C based on the corrected target RPM so that the continuously-variable shifting is performed.

3B and 3C are flowcharts showing a control method of the continuously-variable transmission CVT according to the present invention.

The operation information detector CS1 starts detecting operation information (S10).

In step 10, the detected operation information is always provided to the control section CS3 and the control axis RPM calculating section CS2.

The control unit CS3 determines whether the shift lever is in the parking position, the brake pedal amount is not 0, and the pedal amount of the accelerator pedal is 0, and if not, the control unit CS3 returns to S10 (S20).

In step 20, since the engine and the CVT are directly connected to each other, a problem may arise if the state of the vehicle is not appropriate at the time of starting the engine. Therefore, it is checked whether the engine can be started based on the detected operation information.

 The controller CS3 determines whether the brake pedal amount is appropriate (S30). If the brake pedal amount is not appropriate, the brake is operated to supplement the insufficient pedal amount (S35).

Steps 30 to 35 are for preventing the power from being transmitted to the drive wheels due to a shortage of the pedal amount of the brake at engine startup.

The control unit CS3 determines whether the clutches C1 and C3 have been operated (S40). If the clutches C1 and C3 are not operating, the clutches C1 and C3 are operated (S45).

In steps 40 to 45, this is also intended to prevent the transmission of distorted power to the drive wheels. The clutch has different clutches depending on whether or not a starter motor is used, and when the starter motor is used, the first and third clutches C1 C3 use only the third clutch C3 when the starting motor is not used.

The first clutch C1 is a normally closed type clutch, the clutch is engaged, and the third clutch C3 is a normally open type clutch, which means that the clutch is closed.

The control unit CS3 determines whether the engine is in operation. If the engine is not in operation, the control unit CS3 returns to step 20 and waits (S50). That is, it is determined whether to enter the next state or stay in the start waiting state depending on the start state.

The control axis RPM calculating section CS2 calculates an idling RPM (S60).

In step 60, the idling RPM means the RPM of the motor GM (= control shaft) when the speed ratio of the transmission is infinite. If the RPM at this time is A RPM, the A includes the tolerance.

The control unit CS3 determines whether the RPM of the motor GM is higher than or equal to A RPM (S70). On the other hand, if the RPM of the motor GM is lower than A RPM, the motor GM is driven to increase the speed (S75).

The controller CS3 determines whether the RPM of the motor GM is lower than or equal to A RPM (S80). On the other hand, if the RPM of the motor GM is higher than A RPM, the motor GM is driven for power generation to decelerate (S85).

The control section CS3 judges whether the RPM of the motor GM coincides with A RPM and whether the shift lever is not parked, and if not, returns to step S60 (S90).

Steps 70 through 90 are for maintaining the idle state of the vehicle, and in particular, the RPM of the motor coincides with A in step 90, which means that no power is transmitted to the output shaft even when the clutch is disengaged.

The control unit CS3 determines whether the brake is released (S100). On the other hand, if the brake is not released, the brake is released (S105).

The control section CS3 determines whether the shift lever is in the neutral position or the parking position, and returns to step S90 if not (S110).

The control unit CS3 determines whether the clutches C1 and C3 have been deactivated (S120). On the other hand, if it is not released, the clutches C1 and C3 are deactivated (S125).

If the shift lever is not in the neutral position or the parking position in step 110, it means that the driver has requested the shift such as advancing or retreating (since the power is not transmitted to the drive wheel even if the clutch is already released in step 90) ) Even if the clutches C1 and C3 are deactivated in steps 120 to 125, the vehicle waits in a state in which the vehicle can be immediately driven.

The control axis RPM calculating section CS2 calculates the target RPM of the control shaft based on the operation information detected by the operation information detecting section CS1 (S130)

The control unit CS3 determines whether the RPM of the control axis GMS is higher than or equal to the target RPM (S140). On the other hand, if the RPM of the control shaft GMS is lower than the target RPM, the motor GM is driven by the motor to increase the RPM of the control shaft GMS (S145)

The control unit CS3 determines whether the RPM of the control axis GMS is lower than or equal to the target RPM (S150). On the other hand, if the RPM of the control shaft GMS is higher than the target RPM, the motor GM drives the generator to decelerate the RPM of the control shaft GMS (S155)

The control unit CS3 determines whether the shift lever is neutral or not in parking (S160). On the other hand, if the vehicle is in the neutral position or the parking position, the process returns to step S90.

The control unit CS3 determines whether the engine is in operation. If the engine is in operation, the control unit CS3 returns to step S130. If the engine is stopped, the shift is terminated (S170).

In steps 130 to 170, the target RPM is changed as long as the engine is not stopped, and the shift continues. Particularly in step 160, when the shift lever is in neutral or parked, it means that the vehicle is not in the running state, but that the driving is not stopped completely. Therefore, the vehicle waits in a state in which the shift is possible immediately.

The shift operation of the continuously-variable transmission CVT having the above-described configuration will be described.

The number of teeth of the gears of the first and second planetary gear sets PG1 and PG2 and the speed reducer RG according to the present invention is set as shown in Table 2 below.

The first planetary gear set The second planetary gear set reducer Gear S1 P1 S2 P2 S3 R G1 G2 G3 G4 Number of teeth in gear 29 16 39 21 14 28 30 25 20 25 module 2 1.5

If the continuously variable transmission (CVT) according to the present invention is constructed as in the first embodiment, and the power of 1,000 RPM and 1 kgf.m is input to the input shaft IS of the CVT having the same number of teeth as shown in Table 2, RPM of each axis TM1 (TM2) (GMS) is shown in Table 3 below.

Reduction ratio -3.3 ∞ 10 5 3.3 2,5 2 1.66 1.42 1.25 1.1 0 TM1 (S1) -300 0 100 200 300 400 500 600 700 800 900 1000 TM2 (S2) -269 24 122 219 317 414 512 610 707 805 902 1000 GMS 61 48 44 38 34 28 24 20 14 10 4 0 CMS (TM2-TM1) 31 24 22 19 17 14 12 10 7 5 2 0 T 9.1 100 18 8.6 5.3 3.3 2.3 1.6 0.9 0.6 0.2 0

In Table 3, CMS and T satisfy CMS = TM2-TM1 and T = CMS / TM2 100.

In Table 3, the power input to the first carrier PC1 of the first planetary gearset PG1 is divided into the first connection axis TM1 and the second connection axis TM2, and the two connection axes TM1, The rotation speed of the two connection shafts TM1 and TM2 increases together and the difference CMS of the rotation speeds increases when the difference between the rotation speeds of the two connection shafts TM1 and TM2 decreases (CMS = TM2-TM1) The rotation speed of TM1 (TM2) is decreasing at the same time.

The difference (CMS = TM2-TM1) between the rotational speeds of the two connection axles TM1 and TM2 is output to the control shaft GMS via the rear gear RPG, (CMS) between the rotation speeds of the two connection axes TM1 and TM2 is adjusted by the adjustment of the two connection axes TM1 and TM2 so that the two connection axes TM1 and TM2 are accelerated and decelerated together.

In the above table 3, when the power of 1,000 RPM and 1 kgf.m is input to the first carrier PC1 and the first sun gear S1 rotates at 300 RPM and 1.601 kgf.m, the second sun gear S2 rotates 317 RPM, 1.634 kgf.m. Therefore, the RPM difference between the two sun gears is 17 RPM, 1.634 kgf.m, and the power is transmitted to the control shaft (GMS) through the rear gear (RPG) with 34 RPM and 0.82 kgf.m.

When the first connecting shaft TM1 is used as an output element, the power of the first sun gear S1 and the power transmitted to the second carrier PC2 are combined in the first connecting shaft TM1. If it is considered in the rear gear (KGB) position, it is inputted from the second connection axis TM2 and outputted to the control shaft GMS and the second carrier PC2. Therefore, the torque transmitted to the control shaft (GMS) should be based on the torque of the second connecting shaft TM2.

In the case of the reverse shift, when the input shaft receives 1,000 RPM and the control shaft GMS is in the no-load state in Table 3, the first connection shaft TM1 is at 0 RPM and the control shaft (GMS) is at 48 RPM. When the motor GM drives the motor and the control shaft GMS is accelerated to 61 RPM, the first connection shaft TM1 rotates 300 RPM and the second connection shaft TM2 rotates 269 RPM.

That is, when the motor MG is driven by the motor to increase the speed of the control shaft GMS from the reference value when the CVT is to be driven backward, the reverse shift is performed.

4 is a view for explaining power characteristics of the planetary gear train according to the present invention.

In the graphs below, assume that the two axes on which power is output are the output axis and the control axis, and the X axis of the graph is the RPM output to the output shaft when the maximum RPM of the output shaft is 1,000 RPM, and the Y axis of the graph is 100 HP Is the magnitude of the power output on each axis.

FIG. 4A is a graph showing the magnitude of the power output to the output shaft (left graph) and the control shaft (right graph) as the RPM of the output shaft changes, to explain the power characteristics of the simple planetary gear device.

4A, the magnitude of the power output to the output shaft increases or decreases in proportion to the RPM of the output shaft, the magnitude of the power output to the control shaft is inversely proportional to the RPM of the output shaft, and the graph always shows a straight line connecting the two points .

The above characteristic is that the characteristic of the planetary gear unit is that the graph can not be an absolute curve.

FIG. 4B is a graph illustrating the power characteristics of the planetary gear train based on Table 3. FIG. 4B is a graph showing the magnitude of power output to the output shaft and the control shaft as the RPM of the output shaft changes.

The graph shown in FIG. 4B is curved (as opposed to a universal planetary gear). In particular, the (left) output axis graph shows a sharp increase from 300 RPM to 300 RPM, while the (right) control axis graph shows a sharp decrease to 300 RPM from 300 to 1,000 RPM. .

In the output shaft graph, when the output shaft rotates at 300 RPM, 94.7HP of power is already delivered to the output shaft, and as the RPM of the output shaft increases, the magnitude of the power transmitted to the output shaft also increases.

In the control axis graph, when the output shaft rotates at 300 RPM, 5.3 hp of power is transmitted to the control shaft, and as the RPM of the output shaft increases, the power transmitted to the control shaft decreases. Therefore, the maximum value of the power flowing through the control shaft in the range of 300 to 1,000 RPM, that is, the speed range used in the passenger car, is 5.3 HP. If 100 HP is transmitted to the input shaft of the planetary gear train having the same number of teeth as Table 2, GM's capacity is around 5.3 HP.

The characteristics of the continuously variable transmission (CVT) configured as described above will be described.

The continuously variable transmission (CVT) according to the embodiment of the present invention is based on a planetary gear device and overcomes the structural limitations of the belt type CVT.

The control point for shifting in the continuously-variable transmission (CVT) is unique to the motor (GM), and can be continuously or continuously shifted by the control of the motor (GM). Therefore, a separate reverse circuit (gear) is not required.

The continuously variable transmission (CVT) is capable of starting the engine with a motor (GM) mounted thereon. Therefore, no starting motor is required.

The continuously variable transmission (CVT) does not require a clutch or a torque converter, a control hydraulic part, a drive (braking) clutch, a band brake and the above-mentioned reverse circuit (gear), so that the planetary gear train It is a very simple structure that is the only mechanical element.

Further, the CVT has a very low cost because of its simple structure.
