Abstract

The invention relates to the technical field of automobile shock absorbers, and discloses an automobile shock absorber bushing which comprises the following raw materials by weight: 65-75 parts of natural rubber, 25-35 parts of polynorbornene rubber, 10-25 parts of high abrasion furnace black, 45-55 parts of carbon black N660, 1-4 parts of a promoter, 2-8 parts of zinc oxide, 1-6 parts of paraffin wax, 1-5 parts of an antioxidant, 1-5 parts of a dispersing agent, 3-8 parts of aromatic oil, 1-5 parts of a curing agent, 1-5 parts of a plasticizer and 1-5 parts of a coupling agent. Through simultaneous use of the natural rubber and the polynorbornene rubber, the heat resistance of products is excellent, by simultaneous use of the high abrasion furnace black and the carbon black N660, aging resistance and bending fatigue resistance of the rubber reinforcing system are excellent, the service life is longer, compression permanent deformation is small, rubber tensile strength is high, rebound elasticity is excellent, and the compression permanent deformation is small.

Description

technical field [0001] The invention relates to the technical field of automobile shock absorbers, in particular to an automobile shock absorber bushing. Background technique [0002] With the continuous development of science and technology, people put forward higher and higher requirements for the ride comfort and operation stability of the car. The vehicle suspension system directly affects the dynamic performance of the system, and the spring is almost the core of the dynamic performance of all suspension systems. Because the rubber material itself has the advantages of light weight, impact resistance and high-frequency vibration absorption, coupled with the improvement of rubber and metal bonding technology, metal rubber springs formed by combining metal and rubber, that is, rubber bushings, are widely used in automobile suspension. in the support device in the rack. The metal rubber spring formed by the combination of metal and rubber, that is, the rubber bushing, is...
