Abstract

The invention discloses a parking mechanism for a vehicle. The parking mechanism comprises a parking ratchet wheel, a parking pawl, a transmission assembly, a guiding assembly and a driving assembly. The parking ratchet wheel is provided with multiple ratchet wheel grooves. The parking pawl is rotationally arranged on a speed changer shell of the vehicle. The parking pawl is provided with pawl protrusions engaged with the ratchet wheel grooves. The transmission assembly comprises a transmission rod, a first elastic part and a pushing and pressing block. The pushing and pressing block is arranged on the transmission rod in a sliding and sleeving manner. The first elastic part is elastically matched with the pushing and pressing block. The guiding assembly is arranged to be used for guiding the transmission rod to move in the axial direction of the transmission rod. The driving assembly is used for driving the transmission rod to move in the axial direction and making the first elastic part push and press the pushing and pressing block through elastic force, and accordingly the pushing and pressing block drives the parking pawl to rotate to the lock state. According to the parking mechanism of the embodiment, the collision strength between parts during transmission is reduced when the parking mechanism works, the abrasion degree of the parts in the parking mechanism is reduced, and the working life of the parking mechanism is prolonged.

Description

technical field [0001] The invention relates to the field of vehicle manufacturing, in particular to a parking mechanism for vehicles. Background technique [0002] The transmission of the vehicle is provided with a parking mechanism. When the driver brakes the vehicle, the parking mechanism can assist in braking the vehicle and help the vehicle to stop. In the related art, there are many parts in the parking mechanism of the vehicle, the structure is complex, and it is not easy to assemble, and each part in the parking mechanism is rigid transmission, and the parking ratchet and other parts of the parking mechanism are easily damaged during the parking process. The greater impact force will cause wear and tear, which will lead to the failure of the parking mechanism. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the object of the present invention is ...
