Abstract

The invention discloses an automobile bearing shell. The material of the automobile bearing shell is modified alloy. The material of the automobile bearing shell adopts the modified alloy, so the stress tolerance and the toughness of the automobile bearing shell are greatly improved, and are 2-3 times those of products of the same kind in the market.

Description

technical field [0001] The invention relates to a bearing bush for automobiles. Background technique [0002] The bearing pad is the part where the sliding bearing contacts the shaft and is very smooth. In the prior art, the bearing pads for automobiles are mostly made of wear-resistant materials such as bronze and antifriction alloys. However, the compressive effect is poor and it is easy to break. Contents of the invention [0003] The object of the present invention is to provide a bearing bush for automobiles aiming at the above-mentioned defects in the prior art. [0004] In order to achieve the above object, the technical solution provided by the present invention is: a bearing bush for automobiles, the material is an alloy, and the alloy composition is calculated in parts by weight: 25-35 parts of tungsten carbide, 25-35 parts of titanium carbide, di 22-26 parts of aluminum, 20-24 parts of light rare earth elements, 20-24 parts of heavy rare earth elements, 20-24 ...
