Problems solved by technology

The P gear parking device in the related art generally has scattered parts and takes up a large space in the housing, and the P gear parking device in the related art generally resists the pawl through a torsion spring to prevent the pawl from falling into the parking gear when the vehicle is running. However, the torque provided by the torsion spring is limited, which cannot prevent the pawl from falling into the tooth groove under severe bumpy road conditions, causing the vehicle to lock instantly and causing danger

Embodiment 1

[0046] Such as Figure 1-Figure 3 As shown, the P-speed parking mechanism according to an embodiment of the present invention includes: a housing (not shown in the figure), a parking gear 1, a pawl 2, a stop block 4, an actuator 51 and a pull rod assembly.

[0047] Among them, the housing can be connected to the reducer case, and the parking gear 1 can be connected to the driving force assembly of the vehicle. For example, the parking gear 1 can be fixedly connected to the main reducer gear, and the parking gear 1 can have a locking groove. 14. When the parking gear 1 is locked, the power output can be cut off to realize P-speed parking.

[0048] The pawl 2 is pivotally installed in the housing, the pawl 2 can be pivotally mounted to the housing through a pawl pivot shaft 26, the pawl pivot shaft 26 can be fixedly connected to the housing, and the pawl 2 passes through a through-hole sleeve. Located outside the pawl pivot shaft 26 and in clearance fit with the pawl pivot shaft 26, ...

Abstract

The invention discloses a P-gear parking mechanism and a car. The P-gear parking mechanism comprises a shell, a parking gear, a pawl, a check block, a pull rod assembly and an executing mechanism. Thepawl is pivotally mounted in the shell, and the pawl is spaced from the parking gear in a non-parking state. The check block is fixedly connected with the shell, and located on the side, away from the parking gear, of the pawl. The pull rod assembly is located between the pawl and the check block. The executing mechanism is connected with the pull rod assembly through a cam plate, so that the pull rod assembly is suitable for abutting against the check block and the pawl to push the pawl to rotate to lock the parking gear. A limiting pin is arranged on one of the cam plate and the pawl, and alimiting groove is formed in the other of the cam plate and the pawl. In the non-parking state, the limiting pin stretches into the limiting groove to limit rotation of the pawl. The P-gear parking mechanism is good in gear engagement parking stability and high in structural reliability, a locking structure is designed, and therefore it can be avoided that the car is in gear by mistake when jolting.

Description

Technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and specifically relates to a P-speed parking mechanism and a vehicle with the P-speed parking mechanism. Background technique [0002] The P block parking lock device can safely park the vehicle when the vehicle is stationary or at a low speed to prevent the vehicle from slipping. The P-speed parking device in the related art generally has scattered parts and takes up a large housing space. In addition, the P-speed parking device in the related art generally uses a torsion spring to resist the pawl to prevent the pawl from falling into the parking gear when the vehicle is running. In the tooth groove, but the torque provided by the torsion spring is limited, it is still unavoidable that the vehicle will make the pawl fall into the tooth groove under severe bumpy road conditions, which will cause the vehicle to lock instantly and cause danger. Summary of the invention [0003] The presen...
