Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of motor vehicle parking locking mechanism of the present invention, comprise parking gear 5, park pawl 6, stationary axle 3, return spring 4 and actuating mechanism, parking gear 5 be not arranged on rotatably power must through transmission shaft on, park pawl 6 is arranged on stationary axle 3, and can rotate around it, return spring 4 is sleeved on stationary axle 3, its one end acts in park pawl 6, the other end is fixed on the casing of gearbox, provides restoring force for park pawl 6 returns to unlocked position from lock position.It is mobile that described actuating mechanism is used for driving park pawl 6 to convert between lock position and unlocked position, as Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 5, actuating mechanism comprises parking spring 10 and the gear position locating board 1 being fixedly connected with shift shaft 2, be sleeved on first roller 9 that also can rotate around shift shaft 2 on shift shaft 2 and be sleeved on shift shaft and two blocks of rolling wheel support plates 8 that can rotate around shift shaft, and second roller 7 that also can rotate around own axis on being arranged between two blocks of rolling wheel support plates 8, parking spring 10 is sleeved on shift shaft 2, at gear position locating board 1 and wherein between a rolling wheel support plate 8, its one end acts on gear shift positioning plate 1, the other end acts on this piece rolling wheel support plate 8, this piece rolling wheel support plate 8 offers arc notch 8a at the through hole edge coordinating with shift shaft 2, on shift shaft 2, be disposed radially locating stud 11, this locating stud 11 is arranged in this arc notch 8a, locating stud 11 limits the slewing area of rolling wheel support plate 8 with respect to shift shaft 2, another piece rolling wheel support plate passes through shaft block ring 12 axial restraint on shift shaft 2.The first roller 9 is between two blocks of rolling wheel support plates 8, the diameter of the second roller 7 is less than the diameter of the first roller 9, its axis is parallel with the axis of the first roller 9, and the second roller 7 cylndrical surface and the first roller 9 Cylindrical Surfaces Contacts, makes the first roller 9 serve as the raceway of the second roller 7.
