Automobile fastener structure

Abstract

The invention provides an automobile fastener structure and relates to the technical field of automobile parts. The surface of one end of a fastener body (1) of the automobile fastener structure is provided with a clamping groove (3); one end of an abrasion-resistant part (2) is provided with a sleeving cavity (4); one end of the abrasion-resistant part (2) is provided with an abrasion-resistant surface (6); a boss (5) is arranged on the inner wall of the sleeving cavity (4); one end of the fastener body (1) is sleeved with the abrasion-resistant part (2) through the sleeving cavity (4); and the abrasion-resistant part (2) mainly comprises polyamide, glass fibers and molybdenum disulfide. According to the automobile fastener structure, abnormal sound can be completely avoided, meanwhile, the production process is simplified, the heat treatment process is omitted, the processing technique requirements for personnel are lowered, the risk of hydrogen embrittlement is completely avoided, the quality risk and cost of the fastener are reduced, the usability of the fastener is completely improved, the service life of the fastener is prolonged, and the product competitiveness is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile parts, and more specifically relates to a fastener structure for automobiles. Background technique [0002] With the development of China's economy, automobiles have become the most important means of transportation. In recent years, the auto industry at home and abroad has been committed to promoting vehicle lightweight, energy saving, emission reduction, cost reduction, and performance improvement through technological innovation. Therefore, major OEM companies have invested heavily in manpower, material resources, and financial resources to research new materials and new Technology, etc., and fasteners have always been the direction of parts that are easily overlooked by all OEMs. Many wear-resistant parts in automobiles in the prior art still use the traditional process, that is, to improve the surface strength to improve the local wear-resistant characteristics, but this process has many ...

AI Technical Summary

Problems solved by technology

Many wear-resistant parts in automobiles in the prior art still use the traditional process, that is, to improve the surface strength to improve the local wear-resistant characteristics, but this process has many defects, such as abnormal noise, complicated process, high process cost, Some parts are at risk of hydrogen embrittlement after plating or pickling

Ordinary wear-resistant parts are mostly in the state of metal, and the arc surface is the wear surface. The surface strength is improved through heat treatment to achieve wear resistance. The requirements for metal surface roughness and dimensional machining accuracy are very high. CNC machining after heat treatment is required, and the efficiency is very high. Low, and the market feedbacks that the friction between metals is obvious

However, most of the wear-resistant parts in the prior art are made of metal or composite materials, which have high cost, short life and large unit weight.
