The beneficial effects of the utility model are mainly reflected in:
1, parking driving mechanism is integrated, overall fast easy to assembly, is applicable to various automatic transmission case, transplants superior performance, expand application area;
2, compact structure, saves space, little to the spatial requirement of automatic transmission case, is convenient to the rational deployment of gearbox;
3, the engaging tooth both sides of parking arm are equipped with chamfering, and when vehicle has appearance mistake engage a gear under certain speed of a motor vehicle in the process of moving, parking arm can exit until engage lower than under setting safe speed by parking gear, prevents danger;
4, each component movement connects compact, and energy loss is little, and operation is smooth convenient, is swift in response.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of parking execution device of the utility model.
Fig. 2 is the structural representation at a kind of another visual angle of parking execution device of the utility model.
Fig. 3 is the side schematic view of Fig. 2.
Embodiment
The utility model provides a kind of parking execution device, as shown in Figure 1 to Figure 3, a kind of parking execution device, be made up of parking driving mechanism and parking gear 1, parking driving mechanism connects parking axle and the shifting-position mechanism of vehicle respectively, and parking gear 1 is fixedly installed on the output shaft of vehicle gear box, wherein, parking driving mechanism comprises integrated parking seat 2, gearshift ratchet assembly 3, parking push rod 4 and parking arm 5, integrated parking driving mechanism compact structure, convenience quick for installation.
This integrated parking driving mechanism of refinement, parking seat 2 has a running shaft vertically worn 6, running shaft is interferenceed with the parking axle of vehicle, parking seat 2 is provided with parking arm seat 7 and cam pressing plate 8 towards parking gear 1 side, gearshift ratchet assembly 3 one end stationary axle is connected to running shaft 6, ratchet assembly 3 of shifting gears under running shaft 6 interlock effect has swing offset, gearshift ratchet assembly 3 the other end is pivotally connected gearshift ratchet stage clip assembly 9, gearshift ratchet stage clip assembly 9 connects shifting-position mechanism, parking push rod 4 provided at one is inserted in gearshift ratchet assembly 3, parking push rod 4 the other end has parking push cam 10, parking arm seat 7 is provided with pivot pin 11, parking arm 5 is pivotally connected with pivot pin 11, and with pivot pin 11 for fulcrum has pivotal displacement, in parking arm 5 pivotal displacement process, parking arm 5 is meshed with parking gear 1 and fixes or be separated, the drive hole 12 for the displacement of parking push rod 4 is formed between parking arm 5 and cam pressing plate 8, and parking arm 5 is driven in parking push cam 10.
