State 1:If the lock groove 14 of parking gear 1 is located at 24 position of locking tooth of face ratchet 2, due to rod assembly
On the initial elastic force of elasticity be more than ratchet 2 due to the resistance that the effect of torsion spring 3 compresses to closing piece 8 and hinders closing piece 8 to continue motion,
So as to which elastic component 75 just can smoothly promote closing piece 8, the first round platform section 82 and then promotion ratchet 2 of closing piece 8 without second compression again
Rotated to close to the direction of lock groove 14, when the second round platform section 83 of closing piece 8 moves to block parking confined planes 43 and ratchet is stayed
When between car confined planes 23, synchronously, the locking tooth 24 of ratchet 2 is moved in the lock groove 14 of parking gear 1, synchronously, convex
The parking lock groove 62 of wheel plate 6 turns to the position of roller 91 of leaf spring 9, roller 91 is pressed on the parking lock groove of lobe plate 6
62 bottoms, so that lobe plate 6 is maintained at parking lock as shown in Figure 3 in the power-off state for executing agency 51 (such as motor)
Position.
State 2:If as shown in Fig. 2 during 24 position of locking tooth of the non-face ratchet 2 of the lock groove 14 of parking gear 1, closing piece
8 the first round platform section 82 equally promotes the locking tooth 24 of ratchet 2 close to the gear tooth portions of parking gear 1, when the locking tooth of ratchet 2
24 with after the tooth contact of parking gear 1, ratchet 2 just can not be rotated further, the first round platform section 82 and the ratchet parking of closing piece 8 limit
The rounded contact at the edge of plane 23, the second round platform section 83 of closing piece 8 just can not continue to move, now because executing agency 51 does not turn
The angle specified is moved, lobe plate 6 will be driven to be rotated further, elastic component 75 is gradually compressed, and turns to lobe plate 6 always
When the bottom of parking lock groove 62 contacts with the roller 91 of leaf spring 9, synchronously, executing agency 51 has gone to the angle of setting and broken
Electricity, because the roller 91 of leaf spring 9 compresses moment of torsion caused by lobe plate 6 more than elastic component 75 to pull bar 7 and the anti-work of lobe plate 6
With moment of torsion, so whole parking system remains to be maintained at pre- parked state as shown in Figure 2 after executing agency 51 powers off, due to bullet
Property part 75 be in compressive state, if vehicle occur landslide phenomenon, wheel can drive parking gear 1 to rotate, when the lock of parking gear 1
When only groove 14 turns to 24 position of locking tooth of face ratchet 2, closing piece 8 may proceed to promote ratchet 2 under the thrust of elastic component 75
Rotate and locking tooth 24 is entered in lock groove 14, P gear halting mechanisms have just reached parked state as shown in Figure 3, so as to protect
Card vehicle will not continue to come down over long distances.
It should be noted that in said system running, spacer pin 64 just begins after departing from the locking section 25a of stopper slot 25
Eventually in stopper slot 25 free segment 25b in, without with the peripheral collision of stopper slot 25, do not interfere with the motion of ratchet 2.
When vehicle launch need unblock when, after executing agency 51 receives the instruction that controller is sent, drive lobe plate 6 to
The direction opposite with during parking rotates, and synchronously, lobe plate 6 drives pull bar 7 to move, and the end face limited block 74 of pull bar 7 promotes lock
Block 8, the second round platform section 83 is set to withdraw between block parking confined planes 43 and ratchet parking confined planes 23, due to the second round platform section 83
Wall have small angle, required driving torque during so as to reduce unblock, the locking tooth 24 of ratchet 2 is in torsion spring 3 or lock
Only the locking tooth of the two sides of groove 14 and ratchet 2 24 two have angle contacts side surfaces and the caused locking tooth 24 for making ratchet 2
The lock groove 14 of parking gear 1 is left in the presence of component away from the lock groove 14 of parking gear 1, when lobe plate 6 is rotated further
Stopped operating when being contacted to the non-bottom of parking lock groove 63 with the roller 91 of leaf spring 9, spacer pin 64 synchronously moves to stopper slot
25 locking section 25a, the position of locking pawl 2, ensure that the locking tooth 24 of vehicle ratchet 2 under severe turbulence road conditions also will not
It is strayed into the lock groove 14 of parking gear 1, P gear halting mechanisms return to non-parked state as shown in Figure 1.
P gear halting mechanisms according to embodiments of the present invention, simple in construction, part shape is simple, and parking reliability is high, and energy
The situation for preventing vehicle ratchet 2 in transport condition from falling into the lock groove 14 of parking gear 1 and stopping vehicle false-lock occurs.
The invention also discloses a kind of vehicle.
Vehicle according to embodiments of the present invention has the P gear halting mechanisms of any of the above-described kind of embodiment.According to of the invention real
The vehicle parking reliability for applying example is high.
