Problems solved by technology

[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

Embodiment Construction

[0023] The limit unlocking device of the automatic gear shifter can be divided into two parts: a base 1 and a shift assembly installed on the base through a rotating shaft 3 . see figure 2 , the base 1 has a limited step hole 14, and one end of the flat spring 2 is also connected to the base 1. The shaft hole 15 is used for installing the rotating shaft 3 .

[0024] see figure 1 , The shift assembly includes a limit device 4, a shift lever 6, a return spring 7, a flat pin 8, a limit pin 9, a force transmission mandrel 10, and the like. The power transmission mandrel 10 is placed in the shift rod 6 and can slide freely. There is a strip-shaped hole 12 at the lower end of the shift rod 6. The limit pin 9 is connected to the lower end of the dowel rod and crosses the strip-shaped hole 12. The strip-shaped hole Play a guiding role to the limit pin 9, the axis of the limit pin 9 is perpendicular to the axis of the shift lever 6, and the force transmission mandrel 10 can push th...

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...
