Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the conventional shift device described in Patent Document 1, the actuator for driving the shift switching member includes a motor and a driving force transmission mechanism. In this case, the driving force transmission mechanism requires a relatively large number of parts to transmit the driving force of the motor to the shift switching member. For this reason, a parking device capable of suppressing an increase in the number of parts for switching between the parking lock state and the parking lock release state of a vehicle is desired.

[0006] The present invention has been made to solve the above-described problems, and one object of the present invention is to provide a parking device capable of suppressing an increase in the number of components for switching between a parking lock state and a parking lock release state of a vehicle.

Means for Solving the Problems

[0007] In order to achieve the above object, a parking device according to one aspect of the present invention includes a parking operating member that reciprocates between a parking lock position in a parking lock state of a vehicle and a parking lock release position in a parking lock release state of the vehicle, an air cylinder connected to the parking operating member and reciprocating the parking operating member between the parking lock position and the parking lock release position, and an air supply unit that supplies high-pressure air from an air tank of an air suspension device for adjusting the vehicle height of the vehicle to the air cylinder.

[0008] The parking device according to one aspect of the present invention includes, as described above, an air cylinder connected to the parking operating member and reciprocating the parking operating member between the parking lock position and the parking lock release position, and an air supply unit that supplies high-pressure air from an air tank of an air suspension device for adjusting the vehicle height of the vehicle to the air cylinder. Thereby, the high-pressure air supplied from the air tank of the air suspension device to the air cylinder can switch between the parking lock state and the parking lock release state of the vehicle. That is, in a vehicle provided with an air suspension device, the parking device can be operated only by adding an air supply unit and an air cylinder to the air suspension device. The air supply unit and the air cylinder can be configured with fewer components compared to a motor and a driving force transmission mechanism. As a result, an increase in the number of components for switching between the parking lock state and the parking lock release state of the vehicle can be suppressed.

[0009] In the parking device according to the above-described one aspect, preferably, the air cylinder moves the parking operating member to the parking lock release position when the inside of the air cylinder becomes high pressure by the high-pressure air supplied from the air tank, and the high-pressure air is discharged from the inside of the air cylinder and the inside of the air cylinder becomes atmospheric pressure, thereby moving the parking operating member to the parking lock position.

[0010] With this configuration, when maintaining the position of the parking operating member at the parking lock position, it is only necessary to maintain the inside of the air cylinder at atmospheric pressure, so there is no need to maintain the inside of the air cylinder at high pressure while the vehicle is parked. As a result, since it is not necessary to maintain the inside of the air cylinder at high pressure for a relatively long time, it is possible to suppress the consumption of parts due to high-pressure air.

[0011] In the parking device according to the above-described one aspect, preferably, the air supply unit includes a first valve disposed between the air tank and the air cylinder, and by opening the first valve, high-pressure air is supplied from the air tank to the air cylinder, and after the inside of the air cylinder becomes high pressure by the supplied high-pressure air, the first valve is configured to be closed.

[0012] With this configuration, after the inside of the air cylinder becomes high pressure by the supplied high-pressure air, by closing the first valve, it is possible to easily maintain the pressure inside the high-pressure air cylinder without continuously supplying high-pressure air from the air tank to the air cylinder.

[0013] In the configuration in which the air supply unit includes the first valve, preferably, the air supply unit further includes a second valve for discharging the high-pressure air supplied to the air cylinder to the outside of the air cylinder, and by opening the second valve in a state where the first valve is closed and the inside of the air cylinder is at high pressure, the high-pressure air inside the air cylinder is discharged to the outside of the air cylinder.

[0014] With such a configuration, by opening the second valve while the first valve is closed and the inside of the air cylinder is at a high pressure, the high-pressure air inside the air cylinder can be easily discharged to the outside of the air cylinder so that the pressure inside the air cylinder becomes atmospheric pressure.

[0015] In addition, in the present application, in the parking device according to the above aspect, the following configuration is also conceivable.

[0016] (Additional item 1) In the configuration where the air supply unit includes the second valve, preferably, the air supply unit is configured to discharge the high-pressure air inside the air cylinder to the atmosphere or return it to the air suspension device by opening the second valve while the first valve is closed and the inside of the air cylinder is at a high pressure.

[0017] With such a configuration, when the high-pressure air inside the air cylinder is configured to be discharged to the atmosphere, the inside of the air cylinder can be made atmospheric pressure simply by opening the second valve, so that the device configuration can be simplified. Also, when the high-pressure air inside the air cylinder is configured to be returned to the air suspension device, the high-pressure air discharged from the air cylinder can be reused as the high-pressure air supplied from the air tank to the air cylinder.

[0018] (Additional item 2) In the parking device according to the above aspect, preferably, the air cylinder includes a cylinder housing and a piston rod that linearly moves inside the cylinder housing by high-pressure air, and further includes a connecting member having one end connected to the piston rod and the other end connected to the parking operating member so that the moving direction of the piston rod and the moving direction of the parking operating member are opposite.

[0019] With such a configuration, since the moving direction of the piston rod and the moving direction of the parking operating member are opposite to each other, the structure that reciprocates the parking operating member between the parking lock position and the parking lock release position by the air cylinder can be suppressed from increasing in size in the moving directions of the piston rod and the parking operating member.

Advantages of the Invention

[0020] According to the present invention, as described above, it is possible to provide a parking device capable of suppressing an increase in the number of parts for switching between the parking lock state and the parking lock release state of a vehicle.

Modes for Carrying Out the Invention

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0023] With reference to FIGS. 1 and 2, the configuration of a parking device 100 according to an embodiment of the present invention will be described. The parking device 100 is provided in a vehicle. The parking device 100 is a device for switching between the parking lock state and the parking lock release state of the vehicle. Note that the parking lock state is a state in which the rotation of the vehicle wheels is locked, and the parking lock release state is a state in which the rotation of the wheels is not locked.

[0024] (Overall Configuration of Parking Device) As shown in FIG. 1, the parking device 100 includes a parking gear 10, a parking pole 20, a parking rod 30, a guide portion 40, an air cylinder 50, a connection member 60, and an air supply portion 70. The parking rod 30 is an example of the "parking operation member" in the claims.

[0025] The parking gear 10 is configured to rotate integrally with the wheel. And the parking gear 10 is configured such that the locking claw 21 of the parking pole 20 can mesh with the teeth 11 of the parking gear 10.

[0026] The parking pole 20 is guided to a position (lock position) where it rotates toward the parking gear 10 side and the locking claw 21 and the teeth 11 of the parking gear 10 mesh with each other. And when the locking claw 21 of the parking pole 20 is guided to the lock position, the rotation of the parking gear 10 is locked. That is, when the locking claw 21 of the parking pole 20 is guided to the lock position, a parking locked state is achieved.

[0027] Also, as shown in FIG. 2, the parking pole 20 is guided to a position (lock release position) where it rotates in a direction away from the teeth 11 of the parking gear 10 and the meshing between the locking claw 21 and the teeth 11 of the parking gear 10 is released. And when the locking claw 21 of the parking pole 20 is guided to the lock release position, the rotation of the parking gear 10 is not locked. That is, when the locking claw 21 of the parking pole 20 is guided to the lock release position, a parking lock release state is achieved.

[0028] As shown in FIG. 1, the parking rod 30 is configured to reciprocate between a parking lock position P1 in the parking lock state of the vehicle and a parking lock release position P2 (see FIG. 2) in the parking lock release state of the vehicle. In the following description, the moving direction of the parking rod 30 is defined as the Z direction. Also, in the Z direction, the parking lock position P1 side and the parking lock release position P2 side are defined as the Z1 side and the Z2 side, respectively.

[0029] The parking rod 30 includes a rod portion 31, a cam portion 32, a retraction spring 33, and a support portion 34. The rod portion 31 is a rod-shaped member extending along the Z direction. The cam portion 32 is fixed to the tip of the rod portion 31. The cam portion 32 is configured to reciprocate in the Z direction as the parking rod 30 reciprocates. When the cam portion 32 moves in the direction approaching the parking pole 20 (Z2 side), the cam surface of the cam portion 32 causes the parking pole 20 to rotate so that the locking claw 21 reaches the locked position. Also, as shown in FIG. 2, when the cam portion 32 moves in the direction away from the parking pole 20 (Z1 side), the cam surface of the cam portion 32 causes the parking pole 20 to rotate so that the locking claw 21 reaches the unlocked position.

[0030] As shown in FIG. 1, the retraction spring 33 is, for example, a coil spring or the like. The end portion of the retraction spring 33 on the Z2 side abuts on the Z1 side of the cam portion 32 in the rod portion 31. The end portion of the retraction spring 33 on the Z1 direction side is supported by the support portion 34 by abutting on the Z2 side of the support portion 34 in the rod portion 31. The retraction spring 33 is configured to press the cam portion 32 against the guide portion 40. The guide portion 40 is configured to guide the cam portion 32 moving to the Z2 side toward the parking pole 20. The guide portion 40 faces the parking pole 20.

[0031] The air cylinder 50 is connected to the parking rod 30 and is configured to reciprocate the parking rod 30 between a parking lock position P1 and a parking lock release position P2 (see FIG. 2). Specifically, the air cylinder 50 includes a cylinder housing 51, a piston rod 52, and a return spring 53. The piston rod 52 linearly moves in the Z direction within the cylinder housing 51 by high-pressure air supplied from the Z2 side into the cylinder housing 51. The return spring 53 is attached to the piston rod 52 so as to bias the piston rod 52 toward the Z1 side within the cylinder housing 51. Then, as shown in FIG. 2, when high-pressure air is supplied into the cylinder housing 51, the piston rod 52 moves toward the Z2 side. Also, as shown in FIG. 1, when high-pressure air is discharged from the cylinder housing 51, the piston rod 52 moves toward the Z1 side by the biasing force of the return spring 53. The piston rod 52 is connected to the parking rod 30 by a connecting member 60. Therefore, when the piston rod 52 moves in the Z direction, the parking rod 30 moves in the Z direction.

[0032] One end of the connecting member 60 is connected to the piston rod 52 and the other end is connected to the parking rod 30 such that the moving direction of the piston rod 52 and the moving direction of the parking rod 30 are opposite to each other. Specifically, the connecting member 60 is configured to be rotatable about a central portion of the connecting member 60 as a fulcrum 61. Then, as shown in FIG. 2, when the piston rod 52 moves in the Z2 direction, the connecting member 60 is connected to the piston rod 52 and the parking rod 30 such that the parking rod 30 moves in the Z1 direction. Also, as shown in FIG. 1, when the piston rod 52 moves in the Z1 direction, the connecting member 60 is connected to the piston rod 52 and the parking rod 30 such that the parking rod 30 moves in the Z2 direction.

[0033] The air supply unit 70 is configured to supply high-pressure air from the air tank 210 of the air suspension device 200 for adjusting the vehicle height of the vehicle to the air cylinder 50. That is, an air suspension device 200 is provided in the vehicle where the parking device 100 is provided. The details of the air supply unit 70 will be described later.

[0034] As shown in FIG. 2, the air cylinder 50 is configured to move the parking rod 30 to the parking lock release position P2 when the inside of the air cylinder 50 becomes high pressure due to the high-pressure air supplied from the air tank 210. Specifically, when high-pressure air is supplied into the cylinder housing 51, as the piston rod 52 moves to the Z2 side, the parking rod 30 connected to the piston rod 52 via the connecting member 60 moves to the Z1 side. When the parking rod 30 moves to the Z1 side, the parking pole 20 rotates so that the locking claw 21 reaches the unlock position by the cam surface of the cam portion 32.

[0035] Also, as shown in FIG. 1, the air cylinder 50 is configured to move the parking rod 30 to the parking lock position P1 when the high-pressure air is discharged from the inside of the air cylinder 50 and the inside of the air cylinder 50 becomes atmospheric pressure. Specifically, when the high-pressure air is discharged from the cylinder housing 51, as the piston rod 52 moves to the Z1 side by the biasing force of the return spring 53, the parking rod 30 connected to the piston rod 52 via the connecting member 60 moves to the Z2 side. When the parking rod 30 moves to the Z2 side, the parking pole 20 rotates so that the locking claw 21 reaches the lock position by the cam surface of the cam portion 32.

[0036] (Configuration of the air supply unit) As shown in FIG. 1, the air supply unit 70 includes a first valve 71a disposed between the air tank 210 and the air cylinder 50, and a second valve 71b for discharging the high-pressure air supplied to the air cylinder 50 to the outside of the air cylinder 50. Specifically, the air supply unit 70 includes a valve unit 71 in which the first valve 71a and the second valve 71b are disposed, an air tank valve unit intermediate connection flow path 72 connecting the air tank 210 and the valve unit 71, and a valve unit air cylinder intermediate connection flow path 73 connecting the valve unit 71 and the air cylinder 50. The valve unit 71 includes an air tank side port 71c connected to the air tank valve unit intermediate connection flow path 72, an air cylinder side port 71d connected to the valve unit air cylinder intermediate connection flow path 73 side, an external connection port 71e connected to the outside of the parking device 100, a first flow path 71f connecting the air tank side port 71c and the air cylinder side port 71d in the valve unit 71, and a second flow path 71g connecting the first flow path 71f and the external connection port 71e in the valve unit 71. The first valve 71a is disposed closer to the air cylinder side port 71d than the connection position with the second flow path 71g in the first flow path 71f. The second valve 71b is disposed in the second flow path 71g. Note that the first valve 71a and the second valve 71b are solenoid valves.

[0037] As shown in FIG. 2, the air supply unit 70 is configured such that high-pressure air is supplied from the air tank 210 to the air cylinder 50 by opening the first valve 71a. Specifically, the air supply unit 70 is configured such that, with the first valve 71a and the second valve 71b closed and the air cylinder 50 at atmospheric pressure, by opening the first valve 71a, high-pressure air is supplied from the air tank 210 to the air cylinder 50 through the air tank valve unit intermediate connection flow path 72, the air tank side port 71c, the first flow path 71f, the air cylinder side port 71d, and the valve unit air cylinder intermediate connection flow path 73.

[0038] The air supply unit 70 is configured to close the first valve 71a after the inside of the air cylinder 50 becomes high pressure due to the supplied high-pressure air. Specifically, the air supply unit 70 is configured to close the first valve 71a after the air cylinder 50 becomes high pressure with the first valve 71a and the second valve 71b closed and the supplied high-pressure air. Thereby, in addition to the inside of the air cylinder 50, the portion of the first flow path 71f on the air cylinder side port 71d side rather than the first valve 71a, the valve unit-air cylinder indirect connection flow path 73, and the portion of the second flow path 71g on the first flow path 71f side are in a state filled with high-pressure air. That is, by closing the first valve 71a after the inside of the air cylinder 50 becomes high pressure due to the supplied high-pressure air, high-pressure air is trapped in the inside of the air cylinder 50, the portion of the first flow path 71f on the air cylinder side port 71d side rather than the first valve 71a, the valve unit-air cylinder indirect connection flow path 73, and the portion of the second flow path 71g on the first flow path 71f side.

[0039] As shown in FIG. 1, the air supply unit 70 is configured to discharge the high-pressure air inside the air cylinder 50 to the outside of the air cylinder 50 by opening the second valve 71b with the first valve 71a closed and the inside of the air cylinder 50 being high pressure. Specifically, the air supply unit 70 is configured to discharge the high-pressure air inside the air cylinder 50 to the outside of the parking device 100 through the valve unit-air cylinder indirect connection flow path 73, the air cylinder side port 71d, the portion of the first flow path 71f on the air cylinder side port 71d side rather than the first valve 71a, the second flow path 71g, and the external connection port 71e by opening the second valve 71b with the first valve 71a and the second valve 71b closed and the inside of the air cylinder 50 being high pressure. That is, the air supply unit 70 is configured to discharge the high-pressure air inside the air cylinder 50 to the atmosphere by opening the second valve 71b with the first valve 71a closed and the inside of the air cylinder 50 being high pressure.

[0040] The air supply unit 70 is configured to close the second valve 71b after the pressure inside the air cylinder 50 becomes atmospheric pressure by opening the second valve 71b. Specifically, the air supply unit 70 discharges the high-pressure air inside the air cylinder 50 to the outside of the air cylinder 50 by opening the second valve 71b, so that the inside of the air cylinder 50, the air cylinder indirect connection passage 73 between the valve unit and the air cylinder, the portion of the first passage 71f on the air cylinder side port 71d side of the first valve 71a, and the second passage 71g become atmospheric pressure, and then the second valve 71b is closed.

[0041] (Effects of the present embodiment) In the present embodiment, the following effects can be obtained.

[0042] In the present embodiment, the parking device 100 includes an air cylinder 50 connected to the parking rod 30 for reciprocating the parking rod 30 between the parking lock position P1 and the parking lock release position P2, and an air supply unit 70 for supplying high-pressure air from the air tank 210 of the air suspension device 200 for adjusting the vehicle height to the air cylinder 50. Thereby, the parking lock state and the parking lock release state of the vehicle can be switched by the high-pressure air supplied from the air tank 210 of the air suspension device 200 to the air cylinder 50. That is, in a vehicle provided with the air suspension device 200, the parking device 100 can be operated only by adding the air supply unit 70 and the air cylinder 50 to the air suspension device 200. The air supply unit 70 and the air cylinder 50 can be configured with fewer parts compared to a motor and a driving force transmission mechanism. As a result, an increase in the number of parts for switching between the parking lock state and the parking lock release state of the vehicle can be suppressed.

[0043] Further, in the present embodiment, the air cylinder 50 is configured to move the parking rod 30 to the parking lock release position P2 when the inside of the air cylinder 50 becomes high pressure due to the high-pressure air supplied from the air tank 210. Further, the air cylinder 50 is configured to move the parking rod 30 to the parking lock position P1 when the high-pressure air is discharged from the inside of the air cylinder 50 and the inside of the air cylinder 50 becomes atmospheric pressure. Thereby, when maintaining the position of the parking rod 30 at the parking lock position P1, it is only necessary to maintain the inside of the air cylinder 50 at atmospheric pressure, so it is not necessary to maintain the inside of the air cylinder 50 at a high-pressure state while the vehicle is parked. Thereby, since it is not necessary to maintain the inside of the air cylinder 50 at a high-pressure state for a relatively long time, it is possible to suppress the consumption of parts due to high-pressure air.

[0044] Further, in the present embodiment, the air supply unit 70 includes a first valve 71a disposed between the air tank 210 and the air cylinder 50. And the air supply unit 70 is configured to supply high-pressure air from the air tank 210 to the air cylinder 50 by opening the first valve 71a. Further, the air supply unit 70 is configured to close the first valve 71a after the inside of the air cylinder 50 becomes high pressure due to the supplied high-pressure air. Thereby, after the inside of the air cylinder 50 becomes high pressure due to the supplied high-pressure air, by closing the first valve 71a, it is possible to easily maintain the pressure inside the high-pressure air cylinder 50 without continuously supplying high-pressure air from the air tank 210 to the air cylinder 50.

[0045] Further, in the present embodiment, the air supply unit 70 includes a second valve 71b for discharging the high-pressure air supplied to the air cylinder 50 to the outside of the air cylinder 50. And the air supply unit 70 is configured to discharge the high-pressure air in the air cylinder 50 to the outside of the air cylinder 50 by opening the second valve 71b in a state where the first valve 71a is closed and the inside of the air cylinder 50 is at a high pressure. Thereby, in a state where the first valve 71a is closed and the inside of the air cylinder 50 is at a high pressure, by opening the second valve 71b, the high-pressure air in the air cylinder 50 can be easily discharged to the outside of the air cylinder 50 so that the inside of the air cylinder 50 becomes atmospheric pressure.

[0046] Also, in the present embodiment, the air supply unit 70 is configured to discharge the high-pressure air in the air cylinder 50 to the atmosphere by opening the second valve 71b in a state where the first valve 71a is closed and the inside of the air cylinder 50 is at a high pressure. Thereby, just by opening the second valve 71b, the inside of the air cylinder 50 can be brought to atmospheric pressure, so that the device configuration can be simplified.

[0047] Further, in the present embodiment, the air cylinder 50 includes a cylinder housing 51 and a piston rod 52 that linearly moves inside the cylinder housing 51 by high-pressure air. And the parking device 100 includes a connecting member 60 having one end connected to the piston rod 52 and the other end connected to the parking rod 30 such that the moving direction of the piston rod 52 and the moving direction of the parking rod 30 are opposite to each other. Thereby, since the moving direction of the piston rod 52 and the moving direction of the parking rod 30 are opposite to each other, the structure for reciprocating the parking rod 30 between the parking lock position P1 and the parking unlock position P2 by the air cylinder 50 can be suppressed from being enlarged in the moving direction of the piston rod 52 and the parking rod 30.

[0048] [Modification Example] It should be noted that the embodiments disclosed this time should be considered illustrative in all respects and not restrictive. The scope of the present invention is shown by the scope of claims rather than the description of the above embodiments, and further includes all changes (modifications) within the meaning and scope equivalent to the scope of claims.

[0049] For example, in the above embodiment, the parking device 100 is shown as an example including a connecting member 60 having one end connected to the piston rod 52 and the other end connected to the parking rod 30 (parking operating member) such that the moving direction of the piston rod 52 and the moving direction of the parking rod 30 are opposite. However, the present invention is not limited to this. In the present invention, the parking device may include a connecting member having one end connected to the piston rod and the other end connected to the parking operating member such that the moving direction of the piston rod and the moving direction of the parking operating member are the same.

[0050] Also, in the above embodiment, the air supply unit 70 is shown as an example configured to discharge the high-pressure air in the air cylinder 50 to the atmosphere by opening the second valve 71b in a state where the first valve 71a is closed and the inside of the air cylinder 50 is at high pressure. However, the present invention is not limited to this. In the present invention, the air supply unit may be configured to return the high-pressure air in the air cylinder to the air suspension device by opening the second valve in a state where the first valve is closed and the inside of the air cylinder is at high pressure. Thereby, the high-pressure air discharged from the inside of the air cylinder can be reused as the high-pressure air supplied from the air tank to the air cylinder.

[0051] Also, in the above embodiment, the air supply unit 70 is shown as an example configured to close the first valve 71a after the inside of the air cylinder 50 becomes at high pressure by the supplied high-pressure air. However, the present invention is not limited to this. In the present invention, the air supply unit may be configured not to close the first valve while maintaining the state where the inside of the air cylinder is at high pressure after the inside of the air cylinder becomes at high pressure by the supplied high-pressure air.

[0052] In the above-described embodiment, the air cylinder 50 is configured such that when the high-pressure air supplied from the air tank 210 causes the pressure inside the air cylinder 50 to increase to a high pressure, the parking rod 30 (parking actuating member) is moved to the parking lock release position P2, and when the high-pressure air is discharged from the air cylinder 50 and the pressure inside the air cylinder 50 returns to atmospheric pressure, the parking rod 30 is moved to the parking lock position P1. However, the present invention is not limited to this example. In the present invention, the air cylinder may be configured such that when the high-pressure air supplied from the air tank causes the pressure inside the air cylinder to increase to a high pressure, the parking actuating member is moved to the parking lock position, and when the high-pressure air is discharged from the air cylinder and the pressure inside the air cylinder returns to atmospheric pressure, the parking actuating member is moved to the parking lock release position.
