Description

Vane-type power units embody multi-purpose

 The invention relates to a multi-purpose vane power unit with further improved pumping operability.

In general, the vane pump (VANE PUMP) is a pumping operation in a state in which a plurality of vanes disposed inside the pump housing is rotated and reciprocated by the driving of the rotor to push the fluid sucked from the inlet side of the pump to the outlet side. It is one of the rotary drive system pump apparatus which consists of.

Such vane pumps are mainly used for hydraulic control of automobiles and various mechanical devices, and in particular, it is important to smoothly reciprocate the vanes fitted on the rotor side to ensure stable pumping operability.

A vane pump that conforms to this structure is a rotary vane pump of Patent No. 10-0168333, filed and registered in 1995.

The rotary vane pump of the Patent No. 10-0168333 is equipped with an annular spring inside the pump to elastically push the vanes arranged in the state fitted to the rotor shaft side by elastic force of the annular spring, in particular, at a low temperature or a low speed. Even in the environment, the slide operation for the reciprocating movement of the vanes is smooth and provides a structure that can maintain a stable pumping capacity.

However, the rotary vane pump of Patent No. 10-0168333 is limited to a so-called one-way control structure in which vanes are always elastically protruded on the outer surface of the rotor shaft by using the elastic force of the annular spring. However, there are limitations in implementing additional functions that can be obtained when controlling in two directions to correspond to the reciprocating direction of the vanes. In addition, only one direction works so it performs only one function.

In particular, when the vanes are formed to enable two-way control to correspond to the reciprocating direction [double acting] or [single actuating], vane pumps have a relatively bulky and complicated structure such as pump housing or cam ring. Without changing the structure of the parts or installing additional devices, simply set up only one control device in the form of air or hydraulic to control only the vane's appearance according to the purpose [using only the control fluid pressure]. The cool mechanism of the weather station is created, which can play the role of braking type brake, energy storage [accumulation] and driving bearing [no load].

The present invention has been made to solve the conventional problems as described above,

SUMMARY OF THE INVENTION An object of the present invention is to provide a vane pump device, which is configured to easily adjust hydraulic pressure or flow rate in a manner of controlling the protrusion state of vanes in two directions, among the components of a pump.

In order to realize the object of the present invention as described above,

A pump housing having a cam ring for guiding a pumping operation of the fluid and having a drive shaft installed in a direction passing through the center of the cam ring;

A rotor disposed rotatably by receiving power from the drive shaft inside the cam ring of the pump housing and having a plurality of slot grooves spaced apart from the circumferential side in a radial direction with respect to the rotation axis;

A plurality of vanes disposed in the slot groove side of the rotor to be pumped out of the fluid while being roamed from the slot groove side by the cam ring when the rotor is rotated;

It provides a vane pump device including a vane control unit formed to adjust the pumping force while controlling the appearance of the vanes.

In particular, the present invention includes a vane control unit capable of appropriately controlling the protruding state (length) of the vanes, which is installed in the slot groove side of the rotor to enable the lifting operation, in the two directions. It is possible to easily adjust and set the pumping pressure or flow rate of the fluid while changing the pumping force by controlling the protrusion state.

Therefore, the present invention can control the pumping force with a simple structure when pumping the fluid, thereby ensuring further improved operability and functionality.

Now, for example, let's take a closer look at the advantages of each. The friction brakes of braking systems now used in automobiles and aircraft, all disappear in the form of heat, noise, and fugitive dust, but with hydraulic regeneration using fluids. With the brake system, energy can be recycled more than 90%. In particular, the vane pump type device is considered to be of great value as a braking device for automobiles and aircrafts. In view of its great benefits, the vane pump type device is operated in a situation where abrasion cannot occur due to the first hydraulic drive type. Semi permanent life expectancy. Secondly, the braking operation pushes the vane toward the cam ring by the control hydraulic force, and discharge hydraulic pressure is generated so that it can be collected as it is in the accumulator [[Accumulator] and reused as a vehicle brake or a forward and backward driving power source. Thirdly, the energy saving advantage is great. Third, using this device, which is currently pending, it is easy to use as a device, as a motor [power source], and then as a pump [brake source], it is possible to easily reverse each other. External adjustment device With only a few additional valves or electrical equipment operation, it is easy to revolutionize the process of braking and driving [starting without a cell motor, forward and backward with initial pressure], and therefore wheels and brakes [brake] Service life is expected to be significantly extended, replacement and maintenance time of tires and brakes will be significantly extended, and operating cost will be greatly reduced. In addition, a simple cooling device does not cause vapor lock phenomenon due to brake overheating.

1 and 2 are views schematically showing the entire internal structure of the vane pump apparatus according to an embodiment of the present invention, Figures 3 to 5 is a detailed structure and operation of the vane pump apparatus according to an embodiment of the present invention As the drawings for explanation, reference numeral 2 designates a pump housing. Reference numeral 4 denotes a rotor and reference numeral 6 denotes a vane.

1 and 2, a cam ring A is provided inside the pump housing 2.

The cam ring A has a guide surface A1 for guiding the pumping operation along the inner circumferential surface, and may be disposed inside the pump housing 2 as shown in FIGS. 1 and 2.

The cam ring (A) may be provided in an integral structure with the pump housing (2), or may be provided in a non-integral structure that is removable.

The pump housing 2 has two ports P1 and P2, and the two ports P1 and P2 are spaced apart so that the fluid W can be supplied or discharged in correspondence with the cam ring A. Floating and connected on the outer surface of the pump housing (2).

On the pump housing 2 side, as shown in Fig. 1, a drive shaft B is installed in a direction penetrating through the center portion of the cam ring A. The drive shaft B is not shown in the drawing, but the power source is driven in a conventional manner. It receives and serves to rotate the rotor 4 to be described later to enable the pumping drive.

In addition, for example, a radial bearing B1 may be installed inside the pump housing 2 so as to correspond to the driving shaft B. Then, the drive shaft B can be rotated in a state that is stably supported on the bearing (B1) side.

The pump housing 2 is not shown in the figure so that the seal of the fluid W can be stably maintained during the pumping operation is provided in a structure in which the inner and outer coupling portions are sealed in a conventional manner.

The rotor 4 and the vane 6 are installed in a state in which the pumping operation is possible in correspondence with the cam ring A inside the pump housing 2.

Referring again to FIGS. 1 and 2, the rotor 4 may be disposed inside the guide surface A1 of the cam ring A disposed inside the pump housing 2 as shown in the drawing.

The rotor 4 is connected to the drive shaft (B) to receive power from the drive shaft (B) to rotate about the axis of the drive shaft (B).

The rotor 4 is arranged so that the pumping drive can be rotated when it is arranged to correspond with the cam ring A of the pump housing 2.

For example, the rotor 4 may be set such that the rotational axis is positioned at a position offset from one side and spaced apart from the center side of the cam ring A as shown in FIG. 2.

Then, the rotor 4 is disposed in an eccentric state inside the cam ring A, and as shown in FIG. 2, a pumping space (A) at a point corresponding to a portion of the circumference of the guide surface A1 of the cam ring A ( A2) is formed.

In addition, the ports P1 and P2 of the pump housing 2 are connected to each other so as to communicate with the pumping space A2 so that the fluid W may be introduced and discharged.

The vane 6 is compressed, for example, when the rotor 4 is rotated in one direction, for example, by sucking the fluid W from one of the ports P1 and toward the other of the ports P2. It serves to pump the discharge.

The vanes 6 are disposed at a plurality of points along the circumference of the rotor 4 so that the vane 6 slides from the inside of the rotor 4 toward the circumference outside.

That is, the vanes 6 are inserted into the slot grooves C formed at intervals on the circumferential side of the rotor 4, as shown in FIG. It can be slidably installed.

The slot grooves (C) are provided at a plurality of points along the circumference of the rotor (4) in a state having a groove structure capable of guiding the slide movement of the vanes (6) in the radial direction from the axis of the rotor (4). Is formed.

Then, the vanes (6), the slide movement can be made in a state where one end can be sunk toward the outer peripheral portion of the rotor (4) from the slot groove (C) side.

The rotor 4 and the vane 6 are operated in a state in which the pump housing 2 is rotated forward and backward by the drive shaft B inside the pump housing 2, and as shown in FIG. 3, one port of the pump housing 2. In P1, the fluid W may be pumped toward the other port P2.

That is, the vanes 6 are guided while the end (free end) is in contact with the guide surface A1 side of the cam ring A provided inside the pump housing 2 when the rotor 4 is driven. As shown in FIG. 3, the cam is protruded in a rotational section corresponding to the pumping space A2 inside the cam ring A, and in the remaining rotation section, the operation is performed while being moved toward the slot groove C of the rotor 4. Can be.

Therefore, the vanes 6 are pumped in the state in which the inlet / out operation is repeated inside the cam ring A, and the fluid W is pumped through the two ports P1 and P2 of the pump housing 2. You can do that.

On the other hand, the vane pump device according to an embodiment of the present invention, the vanes 6 and the vane control unit 8 corresponding to.

The vane control unit 8 is formed to control the protruding state (length) of the vanes 6 disposed on the rotor 4 side.

Referring back to FIGS. 1 and 2, the vane control unit 8 includes a first controller D for moving in one direction among the slide directions of the vanes 6, and an operation direction of the first controller D. FIG. And a second controller E for moving the vanes 6 in the opposite direction.

The first controller D may be provided in a structure capable of moving the vanes 6 in a protruding state by pushing the vanes 6 in the outward direction of the rotor 4.

In particular, the first controller D may be formed to move the vanes 6 by pneumatic (or hydraulic).

The first controller (D) may be set such that the pneumatic pressure acts on the slot grooves (C) side in a state disposed outside the pump housing (2).

For example, the first controller D may use a pneumatic pump, and extends into the drive shaft B and the rotor 4 from the outside of the pump housing 2 as shown in FIGS. 1 and 2. Through the pipeline (D1) can be installed so that the pneumatic pressure to each of the slot grooves (C) side in a conventional manner.

Then, the pneumatic pressure acts on the inside of the slot groove C as shown in FIG. 4 by the operation of the first controller D, and the vane 6 is pushed by pneumatic to move the outer side of the circumference of the rotor 4. Can be projected toward.

Although not shown in the drawings, the first controller D is provided in a structure capable of appropriately adjusting the pneumatic pressure acting on the slot groove C side of the rotor 4 while the operation is controlled by a conventional method. Can be.

The second controller E is formed to move the vane 6 in a direction opposite to the operating direction of the first controller D. FIG.

In particular, the second controller E may be formed to move the vanes 6 with elastic force.

The second controller E may use an elastic member that generates a tensile elastic force, and is set such that the tensile elastic force acts in a direction of pulling the vane 6 inside the slot groove C of the rotor 4. Can be.

For example, the second controller E may use a tension coil spring among the elastic members, one end of which is connected to one side of the slot groove C of the rotor 4 as shown in FIG. It may be provided in connection with the vane 6.

Then, the second controller E may be operated to elastically pull the vanes 6 with a tensile elastic force at the slot groove C side.

That is, since the second controller E is operated in a direction in which the vane 6 is elastically pulled inside the slot groove C, if the pneumatic pressure of the first controller D is lower than the elastic force, FIG. As described above, the vane 6 may be pulled with an elastic force and moved toward the inside of the slot groove C.

In the above description, the use of a tension coil spring for generating a tensile elastic force as an elastic member of the second controller E is shown in the description and drawings as an example, but the present invention is not limited to this structure.

For example, the second controller E may use a conventional compression coil spring that generates a compressive elastic force as the elastic member. At this time, although the compression coil spring is not shown in the drawing, the vanes 6 may be set to move elastically toward the inside of the slot groove C by pushing the vanes 6 with a compressive elastic force on the rotor 4 side.

According to the structure of the vane control unit 8 described above, it is possible to appropriately control the protruding state of the vanes 6 arranged on the side of the slot groove C of the rotor 4 by using pneumatic and elastic force.

For example, in order for the vanes 6 to protrude outside the circumference of the rotor 4, a pressure greater than the elastic force of the second controller E is applied to the slot groove C side of the rotor 4. The first controller D is operated to supply the pneumatic pressure.

Then, the vanes 6 having one side elastically connected by the tensile elastic force of the second controller E are moved out of the slot groove C by pneumatic pressure as shown in FIG. It can be operated in a protruding state on the circumferential side.

At this time, the vane 6 is moved in the protruding state as described above only when the air pressure generated in the first controller D is greater than the elastic force of the second controller E, and the air pressure is equal to or more than the elastic force. If it is small, the vane 6 is in a state where it is not operated in the protruding direction.

The vanes 6 operated as described above are outside the circumference of the rotor 4 as described above only in a section where the pumping is performed in the cam ring A of the pump housing 2, that is, the point corresponding to the pumping space A2. Protrudes into the slot groove C side of the rotor 4 while the tip is pressed by the guide surface A1 of the cam ring A in the non-pumping space.

In addition, when the first controller D is operated to release the pneumatic pressure or is smaller than the elastic force of the second controller E in the protruding state as described above, the vane 6 is the second controller E. Pulled back by the elastic force of the rotor 4 is moved toward the slot groove (C) inside.

Therefore, using the pneumatic and elastic force by the first controller (D) and the second controller (E) as described above, the vane (6) in the slot groove (C) side of the rotor (4) in the forward and backward direction The length of the protrusion can be adjusted appropriately while moving.

As described above, the protrusion state of the vanes 6 installed on the rotor 4 side of the pump housing 2 is controlled in two directions by using the first and second controllers D and E of the vane control unit 8. If provided, the pumping flow rate or the hydraulic pressure of the fluid (W) can be easily adjusted in a manner to properly adjust the protruding length of the vanes (6) when the pump is driven.

In particular, the method of controlling the protruding length of the vanes 6 as described above, for example, of the components constituting the vane pump, which is relatively bulky and complicated among the components constituting the vane pump, are not shown in the drawings. Hydraulic and flow rates can be controlled simply without changing the structure or installing additional devices.

Therefore, the present invention described above can drive the rotor 4 of the pump housing 2 as shown in FIG. 3 to pump the fluid W by the pumping action by the vanes 6, in particular, the pumping operation. Since the vane control unit 8 can easily adjust the flow rate and the hydraulic pressure in a manner that appropriately controls the protruding state (length) of the vanes 6 in two directions, for example, the protruding length of the vanes although not shown in the drawings. Compared with the structure of the general vane pump that does not provide a means for controlling the can improve the operability and operability further.

In addition, the vane pump apparatus of the present invention is not limited to a structure in which one rotor 4 is installed inside the pump housing 2.

In FIG. 10, the pump housing inner space is divided into left and right directions to form two spaces, and rotors and cam rings are installed on the two spaces, respectively, so that the two rotors are driven by one drive shaft and rotated. It may be provided in a structure set to be driven.

At this time, the rotors are arranged inside the cam rings in a state in which they are concentric with each other, and the two cam rings are set so that the centers thereof are shifted from each other with the rotation axis of the rotors interposed therebetween.

Then, since pumping spaces are formed at different points in correspondence with the entire rotation section of the drive shaft, the pumping spaces are formed by vanes of one rotor and vanes of the other rotor, for example, when the driving shaft is driven. Since the pumping operation can be made alternately in the pump can be pumped in a state that can minimize the occurrence of the idle section in the entire rotation section of the drive shaft.

One of the reasons for the manufacture of a device capable of operating as described above is the fact that in one case, the driving force can be exerted with one device, and on the contrary, the mode can be easily changed even with a braking device. It's a very useful device, so I'll try. For example, in the case of automobiles, when braking, the brake pads are braked by sliding friction between the physical friction pad and the friction drum, and all of them fly with heat, sound and flame dust. As a system device, if you accumulate it in the accumulator for a while and play it back when necessary, it can be used as a hybrid device that is in full swing these days. That is expected to be over 90% renewable efficiency. In addition, in the case of an airplane, the life of the wheel is extremely short due to the impact force of the landing process. As described above, when the braking force at the time of landing is sent to the accumulator and reused, the landing pressure is 4-5 minutes. Accelerating from before and landing at an accelerated speed relative to the ground (as soon as the wheel touches the ground, immediately changes to braking mode) eliminates the shocking process of braking (relative to ground). Speed "0"], the wheel wear process does not occur, and it is possible to move forward and backward by magnetic force, so that an auxiliary device (aka towing vehicle) is not needed. Will bring profit.

If the proposed device is additionally installed and operated on all human-developed vehicles such as aircraft and automobiles, it is possible to accumulate, regenerate, and operate the braking force easily, thereby achieving a beneficial purpose of expressing multifunctionality. . That is, the hybrid function through energy recycling, the drastic life extension of the tire life of the aircraft, and the forward and reverse, such as a car, can be driven magnetically without external help. In addition, there is very little cause of sudden oscillation. There is no need for a driving self-driving motor. The life of the brake system is greatly increased. Since there is no device such as a friction pad for braking and a device using a closed oil / pneumatic device, there is no theoretical wear out part. Thus lifespan is semi permanent.
