Six-speed automatic transmission gear shifting and parking mechanism

Abstract

The invention relates to a six-speed automatic transmission gear shifting and parking mechanism which comprises a parking mechanism and a gear shifting mechanism. The parking mechanism comprises a parking gear, a parking pawl, a parking roller retention frame assembly, a parking roller retention frame support shaft, a parking roll bar assembly and a parking pawl spring. The parking gear is meshed with the parking pawl. The parking pawl and the parking roller retention frame assembly are sleeved on the parking roller retention frame support shaft. Parking rollers are distributed on the parking roller retention frame assembly. The parking pawl spring is located on the parking pawl. The gear shifting mechanism comprises a gear shifting shaft assembly and a locking pin. A tooth groove is formed in the gear shifting shaft assembly. The locking pin is provided with a steel ball. One end of the parking roll bar assembly is hinged to parking roll bar assembly, and the other end of the parking roll bar assembly is hinged to the gear shifting shaft assembly. The six-speed automatic transmission gear shifting and parking mechanism is simple in structure, reasonable in design, compact, convenient to assemble, and low in maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of transmissions, in particular to a transmission shifting and parking mechanism with a reliable parking locking function. Background technique [0002] At present, with the continuous popularization of automatic transmissions and the further tightening of traffic safety regulations, the technology of automatic transmissions has been continuously innovated. The automatic transmission transmits power through the components of the hydraulic actuator, and the hydraulic components themselves have the inherent characteristics that the separation is not rapid and incomplete; therefore, when the vehicle equipped with the automatic transmission is in neutral, the power is still there due to the incomplete separation of the hydraulic components. Transmission, although the whole vehicle has a brake mechanism, but the risk of failure of the vehicle brake mechanism still exists due to the power still being transmitted, ...

Problems solved by technology

The automatic transmission transmits power through the components of the hydraulic actuator, and the hydraulic components themselves have the inherent characteristics that the separation is not rapid and incomplete; therefore, when the vehicle equipped with the automatic transmission is in neutral, the power is still there due to the incomplete separation of the hydraulic components. Transmission, although the whole vehicle has a brake mechanism, but the risk of failure of the vehicle brake mechanism still exists due to the power still being transmitted, which will lead to the phenomenon of the vehicle slipping unintended by the driver, which will cause driving safety accidents.
