Abstract

The invention provides a parking mechanism and a transmission, and relates to the technical field of vehicle engineering. The parking mechanism comprises a hydraulic driving mechanism, a brake pawl and a pawl pin. The hydraulic driving mechanism comprises a piston cavity, and a piston rod positioned in the piston cavity; a first piston and a second piston are arranged at the two ends of the pistonrod; the outer end surface of the first piston and the opposite end inner wall of the piston cavity form a first pressure chamber; the outer end surface of the second piston, and the opposite end inner wall of the piston cavity form a second pressure chamber; a torsion spring sleeves the pawl pin; a parking push block sleeves the piston rod; the parking push block and the tail end of the brake pawl are correspondingly provided with guide inclined surfaces; a hook part is arranged at the head part of the brake pawl; and the hook part is used for entering a groove of a parking ratchet to stop rotation of a brake wheel when the brake pawl is rotated to the direction of the parking ratchet.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a parking mechanism and a transmission. Background technique [0002] At present, the parking control mechanism of the knob-shifted automatic transmission car usually outputs an electric signal through the knob in the cab, and transmits it to the motor drive mechanism, and the gear shifting shaft is driven by the motor to realize gear shifting. [0003] The motor drive mechanism is installed outside the transmission, causing the transmission to take up too much space in the engine compartment. Contents of the invention [0004] The object of the present invention is to provide a parking mechanism and a transmission to alleviate the technical problem that the existing transmission occupies too much space in the engine compartment. [0005] The parking mechanism provided by the present invention includes: a hydraulic drive mechanism, a brake pawl and a pawl pin, the ...
