Abstract
The invention discloses a buffer block used in an automobile shock absorber. The buffer block is prepared from the following components in parts by weight: 80-84 parts of #3 smoke sheet rubber, 6-8 parts of nitrile rubber buna, 2.2-2.4 parts of stearic acid, 0.4-0.6 part of accelerant M, 1.3-1.5 parts of accelerant TT, 25-30 parts of carbon black, 0.6-0.8 part of anti-aging agent D, 0.4-0.6 part of anti-aging agent 4010, 3-4 parts of zinc oxide, 0.5-0.7 part of paraffin, 1.4-1.6 parts of sulfur and 2.6-3 parts of pine tar. The #3 smoke sheet rubber used in the buffer block is resistant to fatigue and aging and is solid when being combined with metal, so that the #3 smoke sheet rubber is used as a main body material of the buffer block; due to adoption of the accelerants and the sulfur, the thermal resistance, the aging resistance, the impact resistance and the elasticity of the buffer block are improved, the comfort level of people when sitting on an automobile is improved, the tensile strength is 30-34MPa, the elongation rate is 600-620%, the shore type A hardness is 65-68 degrees, the permanent deformation is less than or equal to 15%, the rebound rate is 25-28%, and the service life is prolonged for 1.5-2.0 times.
Description
Technical field
The present invention relates to a kind of automobile absorber buffer block.
Background technology
Along with the development of scientific and technological level, people have proposed more and more higher requirement to the riding comfort of automobile and operational stability.Automobile suspension system directly affects the stationarity of vehicle, so and spring is almost the core of suspension system dynamic performance.Because elastomeric material itself has that quality is light, shock resistance and the easy advantage such as absorbing high-frequency vibration, add the raising of rubber and metal sticking technology, elastomeric material is very extensive in automotive field application.
Vibroshock is an important component part of automobile suspension system, concussion when it is mainly used to suppress rebound after spring shock-absorbing and from the impact on road surface.When through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro movement, and vibroshock is used for suppressing this spring jump.
Vibroshock often can exceed high capacity, and therefore conventional buffer block is assisted use, and the mechanical property of buffer block is had relatively high expectations, and existing buffer block haves much room for improvement.
