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

Abstract

The invention discloses a P-gear parking mechanism and a vehicle. The P-gear parking mechanism comprises a shell, a parking gear, a pawl, a stop block, an executing mechanism and a pull rod assembly,wherein the pawl is pivotally installed in the shell and spaced from the parking gear in a non-parking state, the stop block is fixedly connected with the shell and located on the side, away from theparking gear, of the pawl, the pull rod assembly is located between the pawl and the stop block and connected with the executing mechanism, and the pull rod assembly is suitable for abutting against the stop block to push the pawl to rotate until locking the parking gear, and the movement direction of the pull rod assembly is perpendicular to the pivoting axis of the pawl. The P-gear parking mechanism has good gear engaging and parking stability and high structural reliability, the movement tracks of movement pieces are basically concentrated on one plane, and the size of the mechanism can bereduced.

Description

technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to a P-range parking mechanism and a vehicle with the P-range parking mechanism. Background technique [0002] The P gear parking lock device can safely park the vehicle when the vehicle is stationary or at low speed, preventing the vehicle from sliding. 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 still cannot prevent the pawl from falling into the tooth slot under severe bumpy road conditions, causing the vehicle to lock instantly and causing danger. Contents of the invention [0003] The present invention aims to solve at least on...
