Description

  The present disclosure relates to a parking device.

  Conventionally, as this kind of parking device, one equipped with a hydraulic unit mounted on a vehicle and having a piston rod that moves in a first direction, and a magnetic lock device that regulates movement of the piston rod by magnetic force is proposed. (See, for example, Patent Document 1). Here, in the hydraulic unit, the piston rod is urged to the lock side forming the parking lock state by the elastic force of the return spring and moved to the lock release side forming the parking lock released state by the hydraulic pressure. In addition, the magnetic lock device has a locking contact that can be engaged with a roller (contacted portion) provided on the piston rod and can move in a second direction orthogonal to the first direction, Thus, when the movement of the lock shaft is restricted, the movement of the piston rod is restricted by the contact between the contact portion and the roller.

  When the piston rod and the lock shaft are arranged at right angles as in the above-described parking device, the space occupied by the parking device tends to be large. On the other hand, when the piston rod and the lock shaft are coaxially arranged, the axial length of the parking device tends to be long. In these cases, the parking device becomes large, which is disadvantageous to the mountability to a vehicle.

  The parking apparatus of the present disclosure is mainly intended to improve the mountability to a vehicle.

  The parking apparatus of the present disclosure adopts the following means in order to achieve the above-mentioned main object.

A moving portion including a first shaft member extending along a first axis and moving along the first axis, the elastic force of an elastic member attaching the moving portion to a lock side forming the parking lock state A hydraulic unit that urges the moving unit toward the lock release side to form the parking lock released state by the hydraulic pressure and the hydraulic pressure;
A magnetic unit having a second shaft member extending along a second axis parallel to the first axis and moving along the second axis, the magnetic unit being capable of restricting the movement of the second shaft member by a magnetic force;
A first contact portion that can contact the first contact portion formed in the moving portion, and a second contact portion that can contact the second contact portion formed in the second shaft member; An intermediate pivoting member pivoting about the pivoting axis,

  The parking device of the present disclosure includes a hydraulic unit, a magnetic unit, and an intermediate pivoting member. Here, the hydraulic unit has a moving portion including a first shaft member extending along the first axis and moving along the first axis, and the elastic force of the elastic member forms the parking lock state The movable portion is urged toward the lock side and moved to the lock release side forming the parking lock released state by hydraulic pressure. The magnetic unit has a second shaft member extending along a second axis parallel to the first axis and moving along the second axis, and the magnetic force can regulate the movement of the second shaft member. The intermediate pivoting member is capable of abutting on a first abutting portion capable of abutting on a first abutted portion formed on the moving portion and a second abutted portion on a second shaft member. It has a contact portion and rotates around a rotation axis. Then, the movement of the second shaft member is restricted by the magnetic force, and the first contact portion and the first contact portion are in contact with each other, and the second contact portion and the second contact portion are in contact with each other. At the time of contact, the moving part is held on the unlocking side.

In addition, when the coil 55 is energized, the yoke 57, the second core 53, the plunger 51, the first core 52, the ring member 56, the suction force on the plunger 51 by the second core 53 based on the magnetic flux passing through the yoke 57 The elastic force of 59 causes the plunger 51 to be attracted and locked to the second core 53 side, and accordingly the lock shaft 42 and the transmission shaft 44 are also locked.

  The intermediate lever (intermediate rotation member) 60 is formed in a substantially V-shape as shown in FIGS. 2 to 7 and has a base 62, a first free end 63 and a second free end 64. . The base portion 62 is a base end portion (corner portion) of the first free end portion 63 and the second free end portion 64, and is rotatably supported by a rotating shaft 60s. The pivot shaft 60s extends parallel to the extension direction (first axis) of the piston rod 32 and the extension direction (second axis) of the lock shaft 42, and is supported by the case 31 of the hydraulic actuator 30. There is. As shown in FIG. 5 and FIG. 6, the first free end portion 63 is a first contact portion (FIG. 6) that can contact the upper wall surface (first abutted portion) 33b of the recess 33 of the piston rod 32. Upper left edge portion 63a. As shown in FIGS. 5 and 7, the second free end portion 64 is a second contact portion (on the lower left side in FIG. 7) that can contact the tapered portion (second abutted portion) 42b of the lock shaft 42. Edge portion 64a. In the present embodiment, the parking device 10 is designed such that the distance between the pivot shaft 60s and the second contact portion 64a is longer than the distance between the pivot shaft 60s and the first contact portion 63a. A torsion spring 66 is attached or incorporated to the intermediate lever 60 and the pivot shaft 60s, and the elastic force of the torsion spring 66 biases the intermediate lever 60 in the counterclockwise direction in FIG. Hereinafter, in the present embodiment, the clockwise and counterclockwise forces acting on the intermediate lever 60 in FIGS. 3 and 5 will be referred to as “CW-turn power” and “CCW-turn power”, respectively. In the present embodiment, the parking device 10 is locked based on the elastic force of the spring 59 as compared to the CW rotation power acting on the intermediate lever 60 from the upper wall surface 33 b of the piston rod 32 based on the elastic force of the return spring 36. It is designed such that the sum of the CCW turning force acting on the intermediate lever 60 from the tapered portion 42 b of the shaft 42 and the CCW turning force acting on the intermediate lever 60 by the elastic force of the torsion spring 66 is reduced.

  Next, the operation of the parking device 10 configured as described above will be described. The parking device 10 is configured such that the piston rod 32 and the piston 34 do not supply hydraulic pressure (hydraulic fluid) from the hydraulic control device to the oil chamber 31 f of the hydraulic actuator 30 of the hydraulic unit 20 and deenergize the coil 55 of the magnetic unit 40. Is urged toward the lock side (the lower side in FIG. 2) by the return spring 36, the amount of projection of the piston rod 32 from the case 31 is minimized, and the parking lock state is established (the state of FIG. 2). At this time, in the magnetic unit 40, the lock shaft 42, the transmission shaft 44 and the plunger 51 are integrally urged toward the shaft holder 46 by the elastic force of the spring 59, and the curved surface portion 42c of the lock shaft 42 It is in contact with the surface on the lock shaft 42 side (the lower surface in FIG. 2). Further, in the intermediate lever 60, the side surface (surface on the back side in FIG. 2) of the first free end portion 63 is on the outer periphery of the piston rod 32 on the tip end side than the recess 33 in the piston rod 32 It abuts.

  Then, when shifting from the parking lock state to the parking lock release state according to the change of the shift lever, the hydraulic pressure (hydraulic fluid) is supplied from the hydraulic control device to the oil chamber 31f of the hydraulic actuator 30. At this time, de-energization of the coil 55 of the magnetic unit 40 is continued. When hydraulic pressure is supplied to the oil chamber 31f, the hydraulic pressure moves the piston rod 32 and the piston 34 to the unlocking side (upper side in FIG. 2). Then, the detent lever 21 pivots clockwise in FIG. 2, and the parking lock released state is established (the state of FIG. 4 is reached). At this time, when the upper wall surface 33b of the recess 33 of the piston rod 32 and the first contact portion 63a of the first free end portion 63 of the intermediate lever 60 are aligned, the intermediate CCW power by the elastic force of the torsion spring 66 The lever 60 pivots counterclockwise in FIG. 3, and as shown in FIGS. 4 to 6, the first contact portion 63a of the intermediate lever 60 abuts on the upper wall surface 33b of the piston rod 32. Further, when the lock shaft 42 becomes movable toward the shaft holder 46 with the rotation of the intermediate lever 60, the elastic force of the spring 59 makes the lock shaft 42, the transmission shaft 44 and the plunger 51 integral with the shaft holder 46 side. As a result, the tapered portion 42 b of the lock shaft 42 abuts on the second contact portion 64 a of the intermediate lever 60. When the tapered portion 42 b of the lock shaft 42 comes in contact with the second contact portion 64 a of the intermediate lever 60, the intermediate lever 60 is locked based on the elastic force of the spring 59 in addition to the elastic force of the torsion spring 66. The force from the tapered portion 42b of the shaft 42 also acts as a CCW turning power.

  As shown in FIG. 4, when the parking lock released state is established, when the hydraulic pressure (hydraulic fluid) is supplied from the hydraulic control device to the oil chamber 31f of the hydraulic actuator 30, the hydraulic pressure of the oil chamber 31f is The piston rod 32 and the piston 34 are held on the unlocking side, and the parking lock released state is held.

  Also, when the parking lock released state is established, the hydraulic control device supplies the oil to the oil chamber 31f of the hydraulic actuator 30 along with the stop of the engine (stop of the oil pump driven by the engine). Before the hydraulic pressure decreases, energization of the coil 55 of the magnetic unit 40 is started. When the coil 55 is energized, as described above, the lock shaft 42, the transmission shaft 44, and the plunger 51 are locked. Thereafter, when the hydraulic pressure supplied to the oil chamber 31f of the hydraulic actuator 30 decreases due to execution of idle stop or the like, the elastic force of the return spring 36 moves the piston rod 32 and the piston 34 to the lock side (lower side in FIG. 4) As a result, CW rotation power acts on the first contact portion 63a of the intermediate lever 60 from the upper wall surface 33b of the piston rod 32, but the lock of the lock shaft 42 and the tapered portion 42b of the lock shaft 42 and the second of the intermediate lever 60 The clockwise rotation of the intermediate lever 60 in FIG. 5 can be restricted by the contact with the contact portion 64a. As a result, since the contact (engagement) between the upper wall surface 33b of the piston rod 32 and the first contact portion 63a of the intermediate lever 60 is maintained, the movement of the piston rod 32 and the piston 34 to the lock side is restricted. (The piston rod 32 and the piston 34 can be held on the unlocking side), and the parking lock released state can be held.

  When the parking lock release state is shifted to the parking lock state according to the change of the shift lever, the hydraulic pressure supplied from the hydraulic control device to the oil chamber 31f of the hydraulic actuator 30 decreases and the coil 55 of the magnetic unit 40 is End energization or continue deenergization. Then, the CW rotation power acts from the upper wall surface 33b of the piston rod 32 to the first contact portion 63a of the intermediate lever 60 by the elastic force of the return spring 36, and the second rotation of the intermediate lever 60 is generated by the CW rotation power. A force acts on the tapered portion 42b of the lock shaft 42 from the portion 64a to move the lock shaft 42 downward in FIG. Thus, the intermediate lever 60 is pivoted clockwise in FIG. 5 while the lock shaft 42, the transmission shaft 44 and the plunger 51 are integrally moved downward in FIG. 4, and the first contact portion 63a of the intermediate lever 60 is moved. Separates from the upper wall surface 33b of the piston rod 32, the contact (engagement) between the two is released, and the piston rod 32 and the piston 34 move to the lock side (lower side in FIG. 4). Then, as described above, the detent lever 21 pivots to the lock side (counterclockwise in FIG. 4), and the parking lock state is established (the state of FIG. 2 is reached). The intermediate lever 60 is rotated in the clockwise direction in FIG. 5 before the separation of the first contact portion 63a of the intermediate lever 60 from the upper wall surface 33b of the piston rod 32 is completed. The contact between the second contact portion 64a of 60 and the tapered portion 42b of the lock shaft 42 is released, and the lower surface of the intermediate lever 60 in FIG. 2 abuts on the curved surface portion 42c of the lock shaft 42. Then, when the contact between the first contact portion 63a of the intermediate lever 60 and the upper wall surface 33b of the piston rod 32 is released, the CW rotation power does not act on the intermediate lever 60 from the piston rod 32, and the intermediate lever 60 The CCW rotation force by the elastic force of the torsion spring 66 causes the side surface (the rear surface in FIG. 2) of the first free end portion 63 to abut the outer periphery on the tip end side of the recess 33 in the piston rod 32.

  In the present embodiment, the piston rod (first shaft member) 32 of the hydraulic actuator 30 of the hydraulic unit 20 and the lock shaft (second shaft member) 42 of the magnetic unit 40 are arranged in parallel. As a result, it is possible to suppress an increase in the occupied space of the parking device 10 as compared with the case where the piston rod 32 and the lock shaft 42 are disposed orthogonally. Further, compared with the case where the piston rod 32 and the lock shaft 42 are coaxially arranged, it is possible to suppress an increase in the axial length of the parking device 10. As a result of these, the mountability of the parking device 10 on a vehicle can be improved. Then, before stopping the engine by executing an idle stop or the like, the coil 55 is energized to restrict the movement of the lock shaft 42, the transmission shaft 44 and the plunger 51, whereby the upper wall surface of the piston rod 32 is stopped when the engine is stopped. 33b and the first contact portion 63a of the intermediate lever 60 are in contact with each other, and the tapered portion 42b of the lock shaft 42 and the second contact portion 64a of the intermediate lever 60 are in contact with each other. The movement of the vehicle can be restricted, and the parking lock released state can be maintained.

  In the present embodiment, the distance between the pivot shaft 60s and the second contact portion 64a of the intermediate lever 60 is longer than the distance between the pivot shaft 60s and the first contact portion 63a of the intermediate lever 60. The parking device 10 is designed. As described above, at the time of execution of the idle stop or the like, restriction (locking) of movement of the lock shaft 42 etc. by energization of the coil 55 of the magnetic unit 40 and the upper wall surface 33 b of the piston rod 32 and the middle wall 60 The piston rod 32 and the like are held on the unlocking side by the contact (engagement) with the contact portion 63a and the contact between the tapered portion 42b of the lock shaft 42 and the second contact portion 64a of the intermediate lever 60. , Hold the parking lock released state. The lock shaft 42 necessary to hold the parking lock released state by making the distance between the pivot shaft 60s and the second contact portion 64a longer than the distance between the pivot shaft 60s and the first contact portion 63a. The lock force (the suction force on the plunger 51 by the second core 53, that is, the current supplied to the coil 55) can be reduced. As a result, power consumption of the magnetic unit 40 can be suppressed, and the number of turns of the coil 55 can be reduced to miniaturize the magnetic unit 40.

  In the parking device 10 of the embodiment, the distance between the pivot shaft 60s and the second contact portion 64a of the intermediate lever 60 is longer than the distance between the pivot shaft 60s and the first contact portion 63a of the intermediate lever 60. The parking device 10 is designed to However, parking is performed so that the distance between the pivot shaft 60s and the second contact portion 64a of the intermediate lever 60 and the distance between the pivot shaft 60s and the first contact portion 63a of the intermediate lever 60 are substantially the same. The device 10 may be designed. In addition, the parking device 10 is designed such that the distance between the pivot shaft 60s and the second contact portion 64a of the intermediate lever 60 is shorter than the distance between the pivot shaft 60s and the first contact portion 63a of the intermediate lever 60. It is also possible to

  In the parking device 10 of the embodiment, the torsion spring 66 is attached or incorporated to the intermediate lever 60 and the pivot shaft 60s, and when the parking lock state is formed, the curved surface portion 42c of the lock shaft 42 is intermediate The lever 60 is in contact with the surface of the lock shaft 42 side. However, even when the parking lock state is formed without providing the torsion spring 66, the second contact of the taper portion 42b of the lock shaft 42 and the intermediate lever 60 is performed as in the case of forming the parking lock released state. The contact portion 64a may abut. In this case, when the piston rod 32 and the piston 34 move to the lock release side by hydraulic pressure, the intermediate position is generated by the CCW rotation force acting on the intermediate lever 60 from the tapered portion 42 b of the lock shaft 42 based on the elastic force of the spring 59. The lever 60 pivots counterclockwise in FIG. 3, and the first contact portion 63 a of the intermediate lever 60 abuts (engages) the upper wall surface 33 b of the piston rod 32.

  In the parking device 10 of the embodiment, the magnetic unit 50 of the magnetic unit 40 arranges the ring member 56 on the opposite side of the coil holder 55 from the coil 55 and between the first core 52 and the yoke 57. It was a thing. However, as shown in the parking device 10B of FIG. 8, the magnetic unit 50B of the magnetic unit 40B is permanent on the side opposite to the shaft holder 46 with respect to the coil 55 and between the first core 52 and the yoke 57. The magnet 56B may be disposed. The permanent magnet 56B is annularly formed, and is magnetized so that the outer peripheral side is an N pole and the inner peripheral side is an S pole. In this case, when the coil 55 is not energized, the plunger by the second core 53 based on the magnetic flux (magnetic flux caused by the magnet) passing through the permanent magnet 56B, the yoke 57, the second core 53, the plunger 51, the first core 52, and the permanent magnet 56B. The suction force for 51 and the elastic force of the spring 59 cause the plunger 51 to be attracted to the second core 53 and locked, and the lock shaft 42 and the transmission shaft 44 are also locked. In addition, when the coil 55 is energized, the energization generates a magnetic flux (canceled magnetic flux) for canceling the magnetic flux caused by the magnet, thereby canceling the attractive force of the second core 53 against the plunger 51. The lock shaft 42, the transmission shaft 44 and the plunger 51 are integrally urged toward the shaft holder 46 by only the elastic force.

  In the parking device 10, 10B of the embodiment, the lock shaft 42 and the transmission shaft 44 of the magnetic unit 40 are separately configured, but may be integrally configured.

  FIG. 9 and FIG. 10 are configuration diagrams schematically showing the configuration of the main part of a parking apparatus 110 according to another embodiment of the present disclosure. FIG. 9 shows the case where the parking device 110 is in the parking lock state, and FIG. 10 shows the case where the parking device 110 is in the parking lock release state. The parking device 110 of FIG. 9 and FIG. 10 locks the detent lever 21 of the hydraulic unit 20 of the parking device 10 of FIGS. 1, 2 and 4, the piston rod 32 of the hydraulic actuator 30 of the hydraulic unit 20, and the magnetic unit 40. Instead of the shaft 42 and the intermediate lever 60, parking is performed except that the detent lever 121 of the hydraulic unit 120, the piston rod 132 of the hydraulic actuator 130 of the hydraulic unit 120, the lock shaft 142 of the magnetic unit 140, and the intermediate lever 160 are used. It is substantially the same as the device 10. Therefore, in order to avoid duplication of explanation, the same reference numerals are given to the configurations substantially the same as the parking device 10 of FIG. 1, FIG. 2 and FIG. 4 among the parking devices 110 of FIG. Detailed explanation is omitted.

  As shown in FIG. 1, FIG. 2, FIG. 4, FIG. 9, and FIG. 10, the detent lever 121 of the parking apparatus 110 is a parking apparatus except that it has an abutted portion 127 that can abut on the intermediate lever 160. It is substantially the same as the ten detent levers 21. The piston rod 132 of the parking device 110 is substantially the same as the piston rod 32 except that the piston rod 132 does not have a portion corresponding to the recess 33 of the piston rod 32 of the parking device 10. While the lock shaft 42 of the parking device 10 has the tapered portion 42 b and the curved surface portion 42 c, the lock shaft 142 of the parking device 110 extends from one end of the small diameter portion 42 a and has a smooth outer shape (for example, And the hemispherically curved surface portion 142c, except that the lock shaft 42 is substantially identical.

  The intermediate lever 160 of the parking device 110 is disposed between the detent lever 121 and the lock shaft 142, and one end of the intermediate lever 160 (the left end in FIG. 9 and FIG. 10) is pivotable by the pivot shaft 160s. It is supported. The pivot shaft 160s is orthogonal to the extension direction (first axis) of the piston rod 32 and the extension direction (second axis) of the lock shaft 142 and to a direction orthogonal to a straight line passing through the first axis and the second axis It extends in a direction passing through the sheet of FIG. 9 and FIG. 10), and is supported by the case 31 of the hydraulic actuator 130. Further, the intermediate lever 160 is capable of abutting on the abutted portion 127 of the detent lever 121 on the side of the detent lever 121 on the same end side (right end side in FIG. 9 and FIG. 10) with respect to the pivot shaft 160s. A contact portion 161 is provided, and a second contact portion 162 capable of coming into contact with the curved surface portion 142 c of the lock shaft 142 is provided on the lock shaft 142 side. When the detent lever 121 rotates in the counterclockwise direction in FIG. 9 or 10 from the state in which the abutted portion 127 and the first abutting portion 161 are in contact (engagement) with each other, the intermediate lever 160 is moved. It is formed in the shape which is easy to turn clockwise (it is easy to cancel | disengage contact (engagement) of both) in FIG.9 and FIG.10. In this embodiment, the parking device 110 is designed such that the distance between the pivot shaft 160s and the second contact portion 162 is longer than the distance between the pivot shaft 160s and the first contact portion 161. A torsion spring 166 is attached or incorporated to the intermediate lever 160 and the pivot shaft 160s, and the elastic force of the torsion spring 166 urges the intermediate lever 160 in the counterclockwise direction in FIG. There is. Hereinafter, in this embodiment, the clockwise and counterclockwise forces acting on the intermediate lever 160 in FIGS. 9 and 10 will be referred to as “CW rotational power” and “CCW rotational power”, respectively. In this embodiment, the parking device 110 is based on the elastic force of the spring 59 compared to the CW rotation power acting on the intermediate lever 160 from the abutted portion 127 of the detent lever 121 based on the elastic force of the return spring 36. It is designed such that the sum of the CCW turning force acting on the intermediate lever 160 from the curved surface portion 142b of the lock shaft 142 and the CCW turning force acting on the intermediate lever 160 by the elastic force of the torsion spring 166 is reduced.

  Next, the operation of the parking device 110 configured as described above will be described. The parking device 110 is configured such that the piston rod 132 and the piston 34 do not supply hydraulic pressure (hydraulic fluid) from the hydraulic control device to the oil chamber 31 f of the hydraulic actuator 130 of the hydraulic unit 120 and deenergize the coil 55 of the magnetic unit 140. Is urged toward the lock side (the lower side in FIG. 9) by the return spring 36, the amount of projection of the piston rod 132 from the case 31 is minimized, and the parking lock state is established (the state of FIG. 9). At this time, in the magnetic unit 140, the lock shaft 142, the transmission shaft 44 and the plunger 51 are integrally urged toward the shaft holder 46 by the elastic force of the spring 59, and the curved surface portion 142c of the lock shaft 142 It is in contact with the second contact portion 162. In the intermediate lever 160, part of the detent lever 121 side is the detent lever 121 by the CCW rotation power from the elastic force of the torsion spring 166 and the CCW rotation power from the curved surface portion 142c of the lock shaft 142 based on the elastic force of the spring 59. It abuts on a portion other than the abutted portion 127 on the outer periphery of

  Then, when shifting from the parking lock state to the parking lock release state according to the change of the shift lever, the hydraulic pressure (hydraulic fluid) is supplied from the hydraulic control device to the oil chamber 31f of the hydraulic actuator 30. At this time, de-energization of the coil 55 of the magnetic unit 140 is continued. When oil pressure is supplied to the oil chamber 31f, the oil pressure moves the piston rod 132 and the piston 34 to the unlocking side (upper side in FIG. 9). Then, the detent lever 121 is pivoted clockwise in FIG. 9, and the parking lock released state is established (the state of FIG. 10 is reached). At this time, when the abutted portion 127 of the detent lever 121 and the first abutting portion 161 of the intermediate lever 160 are aligned, the lock shaft 142 based on the CCW rotation power by the elastic force of the torsion spring 166 and the elastic force of the spring 59. 9, the intermediate lever 160 rotates counterclockwise in FIG. 9, and as shown in FIG. 10, the first contact portion 161 of the intermediate lever 160 and the detent lever 121 receive The abutment portion 127 abuts.

  As shown in FIG. 10, when the hydraulic pressure (hydraulic fluid) is supplied from the hydraulic control device to the oil chamber 31f of the hydraulic actuator 130 when the parking lock release state is established, the hydraulic pressure of the oil chamber 31f is The piston rod 132 and the piston 34 are held on the unlocking side, and the parking lock released state is held.

  Also, when the parking lock released state is established, the hydraulic control device supplies the oil to the oil chamber 31f of the hydraulic actuator 130 along with the stop of the engine (stop of the oil pump driven by the engine). Before the hydraulic pressure decreases, energization of the coil 55 of the magnetic unit 140 is started. When the coil 55 is energized, as described above, the lock shaft 142, the transmission shaft 44, and the plunger 51 are locked. Thereafter, when the hydraulic pressure supplied to the oil chamber 31f of the hydraulic actuator 130 decreases due to execution of idle stop or the like, the elastic force of the return spring 36 moves the piston rod 132 and the piston 34 to the lock side (lower side in FIG. 10). As the detent lever 121 is pivoted to the lock side (counterclockwise in FIG. 10) at the same time, the CW rotating power acts on the first abutting portion 161 of the intermediate lever 160 from the abutted portion 127 of the detent lever 121. However, the clockwise rotation of the intermediate lever 160 in FIG. 10 can be restricted by the lock of the lock shaft 142 and the contact between the curved surface portion 142c of the lock shaft 142 and the second contact portion 162 of the intermediate lever 160. it can. As a result, since the contact (engagement) between the abutted portion 127 of the detent lever 121 and the first contact portion 161 of the intermediate lever 160 is maintained, the rotation of the detent lever 121 to the lock side is restricted. The movement of the piston rod 132 and the piston 34 to the lock side can be restricted (the piston rod 132 and the piston 34 are held on the unlock side), and the parking lock released state can be held.

  When the parking lock release state is shifted to the parking lock state according to the change of the shift lever, the hydraulic pressure supplied from the hydraulic control device to the oil chamber 31f of the hydraulic actuator 130 decreases and the coil 55 of the magnetic unit 140 is End energization or continue deenergization. Then, the CW rotating power acts from the abutted portion 127 of the detent lever 121 to the first abutting portion 161 of the intermediate lever 160 by the elastic force of the return spring 36, and the CW rotating power causes the second lever of the intermediate lever 160 to A force acts on the curved surface portion 142c of the lock shaft 142 from the contact portion 162 to move the lock shaft 142 downward in FIG. Thus, the intermediate lever 160 rotates clockwise in FIG. 10 while moving the lock shaft 142, the transmission shaft 44, and the plunger 51 integrally downward in FIG. 10, and the first contact portion 161 of the intermediate lever 160. Is separated from the abutted portion 127 of the detent lever 121 and the contact (engagement) between the two is released, and the detent lever 121 rotates to the lock side (counterclockwise in FIG. 10), and the piston rod 132 and the piston 34 moves to the lock side (lower side in FIG. 10). Then, the parking lock state is established (the state shown in FIG. 9 is obtained). When the first contact portion 161 of the intermediate lever 160 and the abutted portion 127 of the detent lever 121 are released while the intermediate lever 160 rotates clockwise in FIG. The CW rotation power does not act on the intermediate lever 160 from the detent lever 121, and the CCW rotation power by the elastic force of the torsion spring 166 and the CCW rotation power from the curved surface portion 142c of the lock shaft 142 based on the elastic force of the spring 59 A portion of the lever 160 on the detent lever 121 side abuts on a portion of the outer periphery of the detent lever 121 other than the abutted portion 127.

  In this embodiment, the piston rod (first shaft member) 132 of the hydraulic actuator 130 of the hydraulic unit 120 and the lock shaft (second shaft member) 142 of the magnetic unit 140 are arranged in parallel. As a result, it is possible to suppress an increase in the occupied space of the parking device 110 as compared with that in which the piston rod 132 and the lock shaft 142 are disposed orthogonally. Further, compared with the case where the piston rod 132 and the lock shaft 142 are coaxially arranged, an increase in the axial length of the parking device 110 can be suppressed. As a result of these, the mountability of the parking device 110 on a vehicle can be improved. When the engine is stopped, the coil 55 is energized to restrict movement of the lock shaft 142, the transmission shaft 44, and the plunger 51 before stopping the engine due to execution of idle stop or the like. Locking of the piston rod 132 in a state in which the contact portion 127 and the first contact portion 161 of the intermediate lever 160 are in contact with each other and the curved surface portion 142c of the lock shaft 142 and the second contact portion 162 of the intermediate lever 160 are in contact with each other. The sideward movement can be restricted, and the parking lock released state can be maintained.

  In this embodiment, the distance between the pivot shaft 160s and the second contact portion 162 of the intermediate lever 160 is longer than the distance between the pivot shaft 160s and the first contact portion 161 of the intermediate lever 160. The parking device 110 is designed. As described above, at the time of execution of the idle stop etc., restriction (locking) of the movement of the lock shaft 142 etc. by energization of the coil 55 of the magnetic unit 140, the abutted portion 127 of the detent lever 121 and the intermediate lever The piston rod 132 and the like are unlocked by the contact (engagement) of the 160 with the first contact portion 161 and the contact of the curved surface portion 142c of the lock shaft 142 with the second contact portion 162 of the intermediate lever 160. Hold and release the parking lock. The lock shaft 142 necessary to hold the parking lock released state by making the distance between the pivot shaft 160s and the second contact portion 162 longer than the distance between the pivot shaft 160s and the first contact portion 161. The lock force (the suction force on the plunger 51 by the second core 53, that is, the current supplied to the coil 55) can be reduced. As a result, power consumption of the magnetic unit 140 can be suppressed, and the number of turns of the coil 55 can be reduced to miniaturize the magnetic unit 140.

  In the parking device 110 according to the embodiment, the distance between the pivot shaft 160s and the second contact portion 162 of the intermediate lever 160 is longer than the distance between the pivot shaft 160s and the first contact portion 161 of the intermediate lever 160. The parking device 110 is designed to However, parking is performed so that the distance between the pivot shaft 160s and the second contact portion 162 of the intermediate lever 160 and the distance between the pivot shaft 160s and the first contact portion 161 of the intermediate lever 160 are substantially the same. The device 110 may be designed. Also, the parking device 110 is designed such that the distance between the pivot shaft 160s and the second contact portion 162 of the intermediate lever 160 is shorter than the distance between the pivot shaft 160s and the first contact portion 161 of the intermediate lever 160. It is also possible to

  In the parking device 110 according to the embodiment, the torsion spring 166 is attached to or incorporated into the intermediate lever 160 and the pivot shaft 160s, and the piston rod 132 and the piston 34 are unlocked on the unlocking side (upper side in FIG. 9) by hydraulic pressure. When the detent lever 121 moves and rotates clockwise in FIG. 9, the CCW rotation power from the curved surface portion 142 c of the lock shaft 142 based on the CCW rotation power by the elastic force of the torsion spring 166 and the elastic power of the spring 59. Thus, the intermediate lever 160 pivots counterclockwise in FIG. 9, and the first abutment portion 161 of the intermediate lever 160 and the abutted portion 127 of the detent lever 121 abut (engage) with each other. . However, the torsion spring may not be provided. In this case, when the piston rod 132 and the piston 34 move to the unlocking side by hydraulic pressure and the detent lever 121 rotates clockwise in FIG. 9, the curved surface portion of the lock shaft 142 is generated based on the elastic force of the spring 59. The CCW turning force acting on the intermediate lever 160 from 142 c causes the intermediate lever 160 to rotate counterclockwise in FIG. 9, and the first contact portion 161 of the intermediate lever 160 and the abutted portion 127 of the detent lever 121 Contact (engage).

  In the parking device 110 according to the embodiment, the magnetic unit 150 of the magnetic unit 140 arranges the ring member 56 on the opposite side of the shaft holder 46 with respect to the coil 55 and between the first core 52 and the yoke 57. It was a thing. However, as shown in the parking device 110B of FIG. 11, the magnetic unit 150B of the magnetic unit 140B is permanent on the side opposite to the shaft holder 46 with respect to the coil 55 and between the first core 52 and the yoke 57. The magnet 156B may be disposed. The permanent magnet 156B is annularly formed and magnetized so that the outer peripheral side is an N pole and the inner peripheral side is an S pole. The operation of the magnetic unit 140B in this case is similar to the operation of the magnetic unit 40B of the parking device 10B described above.

  In the parking device 110, 110B of the embodiment, the lock shaft 142 and the transmission shaft 44 of the magnetic unit 40 are separately configured, but may be integrally configured.

At the time of contact, the moving part is held on the unlocking side. Therefore, since the first shaft member and the second shaft member are arranged in parallel, it is possible to suppress the increase in the occupied space of the device and the increase in the axial length as compared with those arranged orthogonally or coaxially. Thus, the mountability to a vehicle can be improved. Further, when the engine is stopped by execution of idle stop or the like, the movement of the second shaft member is restricted by the magnetic force, whereby the first abutted portion and the first abutting portion abut and the second abutted portion In the state in which the second contact portion is in contact with the second contact portion, the moving portion can be held on the unlocking side, and the parkin lock released state can be held.
