AI Technical Summary

Technical Problem

In traditional automotive gear shifting systems, the lubrication mechanism is imperfect, leading to dry friction or insufficient lubrication of the friction surfaces, which affects the smoothness of gear shifting and the lifespan of components.

Method used

Design an automotive gear selector brushed gasket assembly with a three-layer structure: an outer thin sheet, a spring steel sheet, and an inner gasket, combining polytetrafluoroethylene, corrugated spring steel, and nitrile rubber materials. The outer thin sheet has a micro-protrusion texture on its surface, and the oil reservoir has a circular hole to store and evenly exude grease. The lithium-based grease has a temperature resistance range of -20 to 120°C.

Benefits of technology

It forms a continuous and stable lubricating film, reduces friction and wear, ensures excellent lubrication of the friction surface, buffers the instantaneous pulling impact during gear shifting, prevents the gasket from shifting, and significantly extends service life.

Abstract

The utility model provides a gear selecting and shifting wiredrawing gasket assembly for an automobile, which relates to the technical field of gasket assemblies and comprises an outer-layer sheet, an oil storage component is arranged on the periphery of the outer-layer sheet and comprises an oil storage pipe, a circular hole is formed in the outer wall of the oil storage pipe, and miniature salient points are fixedly mounted on the outer wall of the oil storage pipe. According to the gear selecting and shifting wiredrawing gasket assembly, the micro-convex-point textures are designed on the surface of the outer-layer sheet, and the pit spaces among the convex points are used for storing lubricating oil, so that a continuous and stable lubricating film can be formed when the wiredrawing is in contact with the gasket, and direct abrasion of a friction surface is effectively reduced; meanwhile, the leakage amount of lubricating grease can be controlled through an annular groove structure in the oil storage assembly, the lost lubricating agent is evenly supplemented in the continuous gear shifting process, it is guaranteed that the friction face is in an excellent lubricating state all the time, and the gear shifting jamming phenomenon is reduced fundamentally; in addition, by means of the elastic characteristic of the wave-shaped spring steel sheets, instant tension impact generated in the gear shifting process can be rapidly buffered, and hard damage is avoided.
