Abstract

The invention provides a parking mechanism which is mounted inside a transmission housing, and comprises a pawl. One end of the pawl is hinged to a pawl mounting frame. A return spring is arranged on the pawl mounting frame. The return spring is connected with the pawl mounting frame and the pawl. A buckle finger is arranged at the front end of the pawl. A parking ratchet is fixedly connected with a drive shaft of a transmission. A clamping groove matched with the buckle finger is formed in the parking ratchet. A parking locking shaft perpendicular to a swing arm and fixedly connected with swing arm is arranged at one end of the swing arm. A pushing rod perpendicular to the swing arm is arranged close to the upper part of the other end of the swing arm. A pawl bulge is arranged at the upper part of the pawl. When the swing arm moves, the pawl bulge is pushed by the front end of the pushing rod, and after the pawl bulge is stressed, the pawl rotates, and the buckle finger is clamped in the clamping groove. The parking mechanism is simple and compact in structure, low in purchasing cost, and high in reliability.

Description

technical field [0001] The invention belongs to the field of transmission parking transmission, and in particular relates to a parking mechanism. Background technique [0002] The parking mechanism has the function of locking the rotation of the transmission shaft when the car stops, which can prevent the car from sliding after parking, and plays an important role in improving the safety performance of the car. At present, the transmission parking mechanism of many passenger cars has a large and complex structure, low reliability, high procurement cost, and a relatively large total weight of the mechanism, which is not conducive to the fuel economy of the vehicle. Contents of the invention [0003] In view of this, the present invention aims to propose a transmission parking mechanism with simple structure, low purchase cost and high reliability, so as to solve the parking problem after parking. [0004] In order to achieve the above object, the technical solution created...
