Situation about being stuck can not occur in handle, therefore shifting shaft still can be with normal rotation, and the shifting shaft compression spring that now rotates makes to stay
Car ratchet clamping is pressed on parking gear tooth top, and after having small movement in vehicle, park pawl can slip over first contact car
Gear tooth, then it is caught under the promotion of spring in teeth groove, it is ensured that the realization of parking function.
Further, there is pin-and-hole, steady pin is interference fit with pin-and-hole on the side face of one end of selector shaft；Have on cam
The groove corresponding with steady pin so that cam cooperates with steady pin, so as to which cam can rotate with selector shaft.
Preferably, selector shaft and the through hole in castellated plates are interference fits.
Preferably, return pin is press-fitted with ratchet for interference.
Preferably, spring is arranged between castellated plates and cam, and one section of spring silk is stretched out at the both ends of spring respectively, with selector shaft
Axis parallel.
Preferably, castellated plates are sole template, and one end has several continuous teeth that irregular curve is formed；The other end has
There is an axis hole；In the edge part of castellated plates, also neck is caught in a neck, one section of spring silk of spring；The size and spring of neck
The diameter of silk is adapted.
Further, cam has preformed hole, another section of spring silk insertion preformed hole of spring.
Preferably, it is interference fit to have the cooperation between axis hole, with selector shaft on cam.
Preferably, ratchet substantially T fonts, the afterbody of T fonts are provided with axis hole, are pressed pawl axis for interference.
Preferably, the yi word pattern part on the head of T fonts, while being provided with return pin-and-hole, while being provided with claw, use
It is adapted in gear grooved.
As a result of such scheme, the invention has the characteristics that：
（1）Structural behaviour stability is high, and compared with traditional halting mechanism, whole mechanism is only made up of 8 parts, wherein there is 3
Standard component, each design of part is simple, and the quantity of part is few, greatly reduces the possibility that whole mechanism breaks down.
