Automatic locating and unlocking device of gearshift

Abstract

A limit unlocking device of an automatic gear shifting device comprises a base, a flat spring which has one end installed on the base, and a gear shifting component; wherein, the base is provided with a semi-cambered spacing step hole, the upper edge of which is corresponding to a spacing groove having six gears from P gear to L gear of an automobile; a stop block of the gear shifting component has a wave-shaped surface provided with at least six wave troughs which are respectively corresponding to the six gears from the P gear to the L gear, and the other end of the flat spring presses on the wave-shaped surface of the stop block; the lower end of a power transmission core bar is connected with a spacer pin, and a flat pin is connected below the spacer pin and presses on a return spring;one end of the spacer pin passes through the spacing step hole on the base and is blocked in the spacing groove at the upper edge by the force of the return spring. The device has the advantages of simple structure, little impact noise, good durability and hand feeling, etc.

Description

technical field [0001] The invention relates to an automobile manipulation control system, in particular to a limit unlocking device for an automatic shifter. Background technique [0002] The existing limit unlocking device of automatic shifter has a complex structure, many parts constituting the shifter, complicated welding tooling, high welding precision requirements, and the materials of the limit teeth on the base and the pawl of the shift lever are all steel. , and the gear position displayed by the shift lever is only determined by the limit teeth. The main defect is that the pawl on the shift lever is in contact with the limit tooth surface on the base of the shifter. The shift lever moves on the tooth surface, and the pawl forms a rigid impact under the action of the spring force, resulting in defects such as large impact noise, poor durability, and poor hand feeling. Contents of the invention [0003] The technical problem to be solved by the present invention i...
