Description

technical field [0001] The invention relates to the technical field of rubber production for automobiles, in particular to an automobile shock-absorbing rubber spring and a preparation process of the automobile shock-absorbing rubber spring. 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, and the spring is almost the dynamic performance of all suspension systems. As the core of the rubber material itself, due to 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 are widely used in automotive suspensions. support device. Our company designs suspension rubber springs for an automobile group, whi...

AI Technical Summary

Problems solved by technology

Our company designs suspension rubber springs for an automobile group, which are installed between the axle and the spring steel plate to support the weight of the frame, ease the vibration and impact of uneven roads on the car, and quickly attenuate the vibration to improve driving comfort. It can reduce the dynamic stress of each part of the car body, greatly improve the vibration damping effect of the vehicle and prolong the service life of the spring steel plate, thereby prolonging the service life of the vehicle. The application number is CN201310687377.4 which discloses a shock absorber for automobiles The ozone-resistant rubber composition is composed of the following raw materials in parts by weight: natural rubber SVR3L95-100, konjac glucomannan 1-2, ethylene thiourea 2-3, hexafluoroacetylacetone 1-2, Nano bentonite 20-25, attapulgite 10-12, high borate calcium borate 4-6, accelerator px1-2, barium stearate 4-7, 8-hydroxyquinoline 1-2, anti-aging agent tnp1-2, Anti-aging agent 4010NA1-2, polyethylene wax 4-6, sulfur 1-1.6, composite filler 23-30, the spring rubber material of the invention has good wear resistance, corrosion resistance, tensile performance, especially ozone resistance Good, 50pphm×40℃×20% stretching, no cracks in 200 hours, but this kind of rubber spring has insufficient toughness, poor shock absorption effect, and prone to fatigue damage
