Abstract

The invention discloses an installation structure of a selection arm neck bush of a gear-shifting control assembly. The installation structure comprises a base body, a selection arm, a shaft pin, the selection arm neck bush and a fixing retainer ring. The base body is rotatably arranged on the shaft pin in a sleeving mode. The selection arm is fixedly arranged on the shaft pin in a sleeving mode. A bush main body of the selection arm neck bush is an elastic neck bush with an axial opening. The shaft pin is sleeved with the bush main body. The bush head of the selection arm neck bush radially extends to form flangings. Splay convex corners are arranged on the flangings circumferentially. The bush main body is pressed between the selection arm and the shaft pin, and the splay convex corners are pressed and padded between the sidewall of the selection arm and the fixing retainer ring. Certain elasticity is produced in the radial direction and the axial direction of the selection arm neck bush, and backlashes of the selection arm after installation are eliminated.

Description

technical field [0001] The invention relates to the field of gear shifting of an automobile chassis, in particular to an inner liner of a selection arm of a steering assembly and an installation structure thereof. Background technique [0002] With the development of the automotive industry and the improvement of customers' awareness of automotive products, the performance and quality requirements of automotive products are getting higher and higher, in terms of product development and customer requirements, among which the shift quality is more prominent. [0003] And the existing shift control assembly such as figure 1 As shown, the ball stud 12 is connected through the shift lever 11, and then the ball stud 12 is connected with the rotating end of the selection arm 5 to drive the selection arm 5 to rotate, and the selection arm is connected to the gear cable to realize the shifting function; the rotation process of the selection arm Because of its excessive assembly clea...
