Description

Gear power transmission system

The invention is a transmission system, especially a gear power transmission system.

According to the general traditional gearbox, by changing the speed ratio between the engine and the wheels, the engine's relatively less wide power band can adapt to our very complex and changeable demands for power when driving. Therefore, when changing gears of the gearbox, it means that for the same wheel speed, the engine speed will change, from a certain speed in one gear to another speed in the next gear.

If the engine speed is pulled up or down, if the process is not handled properly, the engine speed will change suddenly when shifting gears. The inertia of the moving parts inside the engine will react to the car body, and a small part of the vibration will be directly removed from the car body. The engine suspension is transferred to the body, and the rest is transferred from the flywheel to the gearbox, then to the drive shaft, and finally to the wheels. The speed of the vehicle changes suddenly, which creates a sense of impact. The lower the gear, the higher the engine torque amplification ratio, and the more obvious the frustration, so it needs to be improved.

6 together, it is a schematic diagram of the operation of the first transmission wheel set of the present invention. At the same time, referring to FIG. 4, it can be seen from each figure that the first driving gear 110 in the first transmission wheel set 11 is mainly located in the first At the center between the disc body 100 and the second disc body 102, the first driving gear 110 is fixed to the first output shaft 160 in the power output shaft group 16, and the second driving gear 120 is fixed to the second output shaft 160 in the power output shaft group 16 The output shaft 162 is fixed, and the first power output gear 111 in the first transmission wheel set 11 is pivotally connected between the first plate body 100 and the second plate body 102. What is important is that the first power output gear 111 in the first power output gear 111 A linkage gear 1110 meshes with the first driving gear 110, and the first sprocket 1111 on the side of the first linkage gear 1110 is linked with the chain 15.

Referring to Fig. 7 together, it is a schematic diagram of the operation of the second shifting wheel set of the present invention. At the same time, referring to Fig. 4, it can be seen from each figure that the second driving gear 120 in the second shifting wheel set 12 is mainly located in the second The disc body 102 and the first disc body 100 are arranged at the center corresponding to the first driving gear 110, and the second power output gear 122 in the second shifting wheel set 12 is pivotally connected to the first disc body 100 and the second driving gear 110. Among the discs 102, it is important that the second interlocking gear 1220 in the second power output gear 122 meshes with the second driving gear 120, and the second sprocket 1222 on the side of the second interlocking gear 1220 is engaged with the chain 15 Knot.

Refer to FIG. 8 together, which is a schematic diagram of the operation of the free gear of the present invention. Each free gear 13 is pivoted between the first plate body 100 and the second plate body 102, and each of the free gears 13 is mainly located between the first sprocket 1111 and the second sprocket 1222, because each of the gears 13 is only connected to the chain 15 meshing can therefore assume an idling state. It can be seen from the above that the power input shaft 140 will mainly drive the sprocket 14 and continue to provide power. When the gearbox device 2 is not activated, the respective gears 13 are simultaneously driven through the chain 15. Since the respective gears 13 rotate independently, Therefore, it will not mesh with the first driving gear 110 and the second driving gear 120. At this time, in order to prevent the chain 15 and other sprockets from being frustrated or even damaged during rotation, after the chain 15 and the driving sprocket 14 are connected, the chain 15 and The free gear 13 meshes. Since the free gear 13 is not affected by any external force, it can rotate freely, allowing the chain 15 to remain engaged before engaging the free gear 13, so as to reduce the aforementioned frustration and even structural damage.

The aforementioned power output shaft group 16 is mainly connected to the gearbox device 2. The first output shaft 160 and the second output shaft 162 in the power output shaft group 16 respectively drive gear mechanisms with different gear ratios. When the first output shaft needs to be activated 160 is connected to the gear mechanism, the second disc body 102 is driven by the motor 19 connection. At this time, the second disc body 102 rotates so that the first power output gear 111, the second power output gear 122 and the free gear 13 rotate simultaneously, and the first The first driving gear 110 fixed by the output shaft 160 mainly meshes with the first interlocking gear 1110 in the first power output gear 111. When the first sprocket 1111 is linked via the chain 15 to make the first power output gear 111 rotate, and The first driving gear 110 meshed with the first power output gear 111 rotates synchronously, thereby driving the first output shaft 160 to operate the linked gear mechanism.

In addition to the first type of speed change described above, when the second type of speed change is required, that is, when the second output shaft 162 drives the gear mechanism with the corresponding gear ratio, the motor 19 acts again and is connected to drive the second disc body 102. When the second disc body 102 rotates again, the first power output gear 111 that was originally meshed with the first driving gear 110 is disengaged. The second disc body 102 rotates at the same time the second power output gear 122 is rotated and interacts with the second driving gear. 120 meshes, and the second driving gear 120 drives the second output shaft 162 in the power output shaft group 16 to rotate, so as to achieve the start of the second type of speed change.

It is worth mentioning that the aforementioned chain 15 can be an elastic chain, which is mainly retracted by the force of a spring to reduce vibration and noise during the operation of the engine. Because the chain is elastic, it can absorb the vibration during operation. Vibration, to achieve the principle of dual-mass flywheel.

Furthermore, one end of the aforementioned tension adjusting member 18 is provided with a tension gear 180. The tension gear 180 mainly meshes with the chain 15. Through the tension adjusting member 18, an elastic force is generated toward the chain 15. When the chain 15 rotates the disc assembly 10 to shift speed During operation, expansion or contraction occurs. The tension adjustment member 18 can control the tension state of the chain 15, and the tension gear 180 meshes with the chain 15 to help the chain 15 adjust the tension and fix the front and back at the same time. Direction of transmission.

Please also refer to FIG. 9, which is a schematic diagram of the structure of a chain combined with a first interlocking gear and a second interlocking gear according to the present invention. In this embodiment, the first sprocket 1111 on the side of the first interlocking gear 1110 is a plurality of side-by-side arranged and linked to the chain 15 respectively. The second sprocket 1222 on the side of the second interlocking gear 1220 is a plurality of side-by-side arranged and linked with the chain 15 respectively. The first sprocket 1111 and the second sprocket 1222 take three side by side as an example. The relative free gear 13 and the driving sprocket 14 are correspondingly arranged corresponding to the number of the first sprocket 1111 and the second sprocket 1222. When three chains are set The overall action method at 15 o'clock is the same as the above, but it can increase the pulling force effect during the overall operation. For example, the pulling force of a single chain 15 is 3N, when the chain 15 is three, the pulling force is increased to 9N, so that the overall operation greatly reduces the breakage. risks of.

It can be seen from the above that the present invention mainly utilizes the combination of the rotating disc set 10, the first shifting wheel set 11, the second shifting wheel set 12, the plural free gears 13, the plural driving sprockets 14, the chain 15 and the power output shaft group 16. , Effectively improve the shortcomings of traditional clutches that rely on friction to transmit power, and the torque is too large and easy to slip, and can reduce the space of traditional clutches.
