Embodiment Construction

[0030] The present invention will be further described below in conjunction with the drawings.

[0031] Such as figure 2 As shown, a schematic diagram of a screw-in type shift limiter for an automobile of the present invention. The automobile screw-in shift limiter includes a shift limiter housing, a shift limiter housing screw-in cover 400 and a shift limiter push rod. The shift limiter housing is a hollow cylinder. Body structure, the shift limiter housing is axially elastically sleeved on the shift limiter push rod, and the outer surface of the shift limiter housing screw-in cover 400 is provided with screw threads to limit the shift The gear housing screw-in type jacket 400 is fixedly sleeved on the shift limiter housing. figure 1 The specific structure of the existing shift limiter is shown. The elastic socket is connected by winding a spring arranged in the shift limiter housing with one end of the limit block to achieve contact connection, and the steel ball at the front ...

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

Technical field [0001] The invention relates to an automobile shift limit device and a manufacturing method of its push rod component, in particular to a shift limiter in contact with the shift fork of an automobile shift mechanism and a manufacturing method of its push rod component, belonging to automobiles Transmission components field. Background technique [0002] The automobile shift limiter is a device used to realize the shift operation of the automobile gearbox and stabilize the position of the gearbox fork. In the drawings of the description figure 1 The specific structure of the existing automobile shift limiter is shown. This kind of automobile shift limiter includes a shift limiter housing and a shift limiter push block. The shift limiter housing has two ends With an open cylinder structure, the shift limiter push block includes a push block body and a steel ball embedded in the head of the push block body. The push block body is arranged in an opening at one end of...
