Problems solved by technology

In the related technology, the parking base and the guide plate are arranged on the transmission housing through bolts, the positioning accuracy is low, the assembly is complicated, and the precision of the parts is high, and the force on the parking base or the guide plate will act on the transmission through the bolts. On the housing, the strength requirements for the transmission housing and bolts are higher, and the risk of bolts loosening due to impact loads is greater
In addition, the installation method of bolts needs to occupy a large space

Abstract

The invention relates to an automatic gearbox parking locking mechanism, which comprises a parking gear, a parking pallet, an executing pin, a guide plate and a parking base, wherein the parking gear is arranged on a middle shaft of the a gearbox; the parking pallet is engaged with the parking gear; the executing pin is used for driving the parking pallet to be engaged with the parking gear; the guide plate is used for guiding the executing pin to move; the parking base is used for carrying the executing pin to stress; the guide plate is clamped and connected onto the parking base; the executing pin passes through the guide element; one end of the parking pallet is connected with a pallet pin in a sleeving way and rotates around the pallet pin; the other end of the parking pallet is rotationally arranged inside the gearbox; in addition, the parking pallet rotates between the locking position engaged with the parking gear and a release position disengaging from the parking gear. The automatic gearbox parking locking mechanism has the advantages that the structure is compact; the parts are few; the loosening risk is low.

Description

technical field [0001] The invention relates to a technology in the field of automobile transmission, in particular to a parking mechanism for an automatic transmission. Background technique [0002] In the parking mechanism of the existing automatic transmission, the parking base realizes the parking function by cooperating with the pawl, the push rod assembly and the parking gear, and provides a supporting point for the push rod assembly in the parking process. During the movement of the push rod assembly, a good guiding effect is required, and in the non-P state, it is necessary to prevent the shaking noise of the push rod assembly due to vibration, and the guide plate plays this role. In the related technology, the parking base and the guide plate are arranged on the transmission housing through bolts, the positioning accuracy is low, the assembly is complicated, and the precision of the parts is high, and the force on the parking base or the guide plate will act on the ...
