Automotive manual gear shifter convenient and fast to assemble and capable of adjusting clearance automatically

Abstract

The invention discloses an automotive manual gear shifter convenient and fast to assemble and capable of adjusting a clearance automatically. The automotive manual gear shifter comprises a base, a joystick, a ball head, a gear selection arm, a connection rod and a pin shaft. The gear selection arm is connected with the connection rod through a spherical bearing. Arc elastic pieces are arranged on the outer circle face of the spherical bearing. A seam adjusting mechanism is arranged between the base and the ball head. A U-shaped elastic clamp is arranged at the end of the pin shaft. A U-shaped positioning groove and limiting stop blocks are arranged on the end face of the gear selection arm. When friction wear exists between the match faces of the arc elastic pieces and the gear selection arm in use, the arc elastic pieces can compensate for the abrasion loss of the match faces automatically; when friction wear exists between the match face of the ball head and the match faces of an upper ring seat and a lower ring seat, an upper spring and a lower spring can push the upper ring seat and the lower ring seat to move, so that the clearance between the ring seats and the ball head is reduced automatically, and the failure rate can be lowered greatly; and no special tool is needed in the U-shaped elastic clamp assembling process, assembling is convenient and fast, and working efficiency is high.

Description

Technical field [0001] The invention relates to an automobile component, in particular to an automobile manual shifter. Background technique [0002] The automobile gear shifter includes a base, a joystick, a gear selector arm, etc. The joystick is fixed on the base by joint bearings, the gear selector arm is fixed on the base by a pin shaft, and the gear selector arm is connected to the joystick through a connecting rod. The ball head is connected. [0003] In the prior art, the spherical bearing connecting the gear selector arm and the connecting rod does not have the function of automatically compensating the amount of wear. When the shifter is used for a long time, the mating surface between the spherical bearing and the gear selector arm will wear out, and the mating surface gap will gradually Increased, which in turn leads to reduced bearing accuracy, increased gear shift noise, and worse shift operation sensitivity and comfort. [0004] At the same time, the articulated bear...

AI Technical Summary

Problems solved by technology

[0006] In view of this, the purpose of the present invention is to provide a kind of automobile manual shifter that assembles quickly and can automatically adjust the gap, to solve the problem that the joint bearing of the automobile shifter in the prior art cannot automatically adjust the fit clearance, and the automobile shifter The fit gap between the upper spherical bearing and the selector ring will gradually increase with the wear of the mating surface, which will lead to the technical problems of poor shift sensitivity, increased abnormal noise, and poor operating comfort; and solve the technical problems of the selector arm The technical problem of low efficiency in assembly with the pin shaft
