Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of motor vehicles parking locking mechanism of the present invention, including parking gear 5, park pawl
6th, fixing axle 3, return spring 4 and actuating mechanism, parking gear 5 be not rotatably arranged on power must through power transmission shaft
On, park pawl 6 is arranged in fixing axle 3, and can rotate around it, and return spring 4 is sleeved in fixing axle 3, and its one end acts on
In park pawl 6, the other end is fixed on the casing of change speed gear box, is that park pawl 6 returns to unlocked position from lock position
Restoring force is provided.Described actuating mechanism is used for driving park pawl 6 to convert movement between lock position and unlocked position, such as schemes
1st, shown in Fig. 2, Fig. 3 and Fig. 5, actuating mechanism includes parking spring 10 and the gear location-plate 1 being fixedly connected with shifting shaft 2, set
It is contained on shifting shaft 2 and around the first roller 9 that shifting shaft 2 rotates and can be sleeved on shifting shaft and can be around the two of shifting shaft rotation
Block rolling wheel support plate 8, and it is arranged on the second roller 7 that is upper between two blocks of rolling wheel support plates 8 and can rotating around oneself axis, stay
Car spring 10 is sleeved on shifting shaft 2, and between gear location-plate 1 and one of rolling wheel support plate 8, its one end acts on
On gear location-plate 1, the other end acts on this block rolling wheel support plate 8, and this block rolling wheel support plate 8 is being coordinated with shifting shaft 2
Through hole edge has arc notch 8a, has been disposed radially alignment pin 11 on shifting shaft 2, and this alignment pin 11 is located at this arc
