Suspended shock absorbing bushing prepared from novel material

Abstract

The invention discloses a suspended shock absorbing bushing prepared from a novel material. The suspended shock absorbing bushing comprises an inner metal framework, an outer framework and a middle elastic layer. The middle elastic layer is arranged between the inner metal framework and the outer framework and is fixedly connected with the inner metal framework and the outer framework. The middle elastic layer is made of polyurethane. The suspended shock absorbing bushing overcomes the defects in the prior art, the main bottleneck of the shock absorbing bushing is the service life of an elastic material, a polyurethane material better in engineering performance is used for preparing the elastic material, so that the service life is prolonged and stability is improved. The polyurethane is better than natural rubber in the aspects of temperature stability and the wear resistance performance, and experiment results show that the service life of a shock absorber can be prolonged by two times or smaller.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a suspension shock absorbing bush of a new type of material. Background technique [0002] With the continuous development of science and technology, people put forward higher and higher requirements for the ride comfort and handling stability of the car. The car suspension system directly affects the ride comfort of the car. Because the rubber material itself has light weight, impact resistance and easy absorption Due to the advantages of high-frequency vibration and the improvement of the bonding technology between rubber and metal, the rubber bushing combined with metal and rubber is widely used in the support device in the automobile suspension. Its working principle is to use the high damping property of the rubber material. When the shock-absorbing bush is subjected to vibration and impact, the vulcanized rubber element that acts as a buffer can convert part of the kinet...

AI Technical Summary

Problems solved by technology

Natural rubber has poor heat resistance and is easy to age

When the natural rubber ages rapidly, the road feeling of the vehicle is blurred, and the car suddenly turns and responds slowly when encountering uneven roads, and even abnormal chassis noises

The shock-absorbing bushing is subject to various external forces when the vehicle is running. There are various forces such as extrusion, friction, and twisting between the rubber and the metal. In addition, the weather resistance of natural rubber is poor, and the service life of the product is short. Regular inspection and replacement are required.
