Abstract

The invention relates to an automobile screw-in type gear-shifting limiting stopper which comprises a gear-shifting limiting stopper shell, a gear-shifting limiting stopper shell screw-in type housing and a gear-shifting limiting stopper push rod. The gear-shifting limiting stopper shell is of a hollow barrel structure. The gear-shifting limiting stopper push rod comprises a push rod bearing end and a push rod connecting end. An arc-surface groove is formed in the end surface of the push rod bearing end and internally provided with a bearing steel ball. A columnar groove is formed in the end surface of the push rod connecting end and internally provided with a reset spring. The invention further relates to a manufacturing method for the gear-shifting limiting stopper push rod. The manufacturing method comprises the steps of punching of an arc-surface hole, turning of a datum hole, turning of an outer circle of the head, turning of an outer circle of the tail portion, turning of a chamfer, groove punching, turning of an inner hole, grinding of an outer circle of the head, arc forming and the like. According to the automobile screw-in type gear-shifting limiting stopper and the manufacturing method for the gear-shifting limiting stopper push rod, the push rod is elastically connected with the gear-shifting limiting stopper shell, the effective work travel of the automobile gear-shifting limiting stopper is substantially extended, and the automobile screw-in type gear-shifting limiting stopper has the characteristics of simple and reliable structure and wide application range.

Description
