Gear selecting and shifting wiredrawing fixed joint structure

Abstract

The invention discloses a gear selecting and shifting wiredrawing fixed joint structure. The gear selecting and shifting wiredrawing fixed joint structure comprises an installation support, wherein the installation support is a main installation supporting structure of a vehicle flexible shaft mechanism, a gear shifting limiting groove and a gear selecting limiting groove are formed in the installation support, and the gear shifting limiting groove and the gear selecting limiting groove are symmetrically distributed about the center point of the installation support; a gear shifting flexible shaft located in the gear shifting limiting groove, wherein a gear shifting sleeve is arranged at the front end of the gear shifting flexible shaft; and a gear selecting flexible shaft located in the gear selecting limiting groove, wherein a gear selecting sleeve is arranged at the front end of the gear selecting flexible shaft. According to the gear selecting and shifting wiredrawing fixed joint structure, a flexible shaft fixed joint sleeve is designed to be a fixed joint with telescopic clamping feet, and an outer diameter of the sleeve is changed through stretching and retracting, so that matching relationships between the sleeve and a support installation groove are changed, a structure is more compact, the anti-disengaging effect is better, and the situations of fracture and loss possibly existing in an assembly and maintenance process are avoided.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a wire drawing fixing joint structure for gear selection and shifting. Background technique [0002] With the development of automobile technology, drivers put forward higher requirements for the comfort of automobile shifting. The direct-operated control structure of MT gearbox cannot meet the requirements of drivers. The remote control mechanism structure transmitted through flexible shafts has been widely used. The fixed joint structure connecting the shift flexible shaft to the whole vehicle plays a key role in the strength of the flexible shaft, and at the same time, the assembly and maintainability of the flexible shaft also need to be considered. [0003] At present, most of the methods on the market use plastic buckles to improve the pull-off force of the flexible shaft sleeve after installation. However, due to the small size of the plastic buckles, there may be break...
