Elastic side bearing body material for bogie of rail wagon

Abstract

The invention relates to a part vibration reducing material of a rail wagon, in particular to an elastic side bearing body material for a bogie of the rail wagon, which is used for manufacturing the elastic side bearing body for the bogie. The elastic side bearing body material comprises the following components by weight part: 80-110 parts of natural rubber, 10-30 parts of butadiene rubber, 3-8 parts of zinc oxide, 0.5-1.5 parts of stearic acid, 0.2-2.0 parts of aging resisters 4010NA, 0.2-2.0 parts of aging resisters D, 0.2-2.0 parts of microcrystalline wax, 0.2-2.0 parts of dispersing agents D-4A, 0.5-1.5 parts of accelerating agents CZ, 1.0-3.0 parts of sulfur, 0.5-1.2 parts of accelerating agents TMTD, 10-40 parts of intermediate super-abrasion furnace carbon blacks, 5-20 parts of fast extruding furnace carbon blacks and 0-10 parts of low-temperature plasticizers. The JC type elastic side bearing body of the rail wagon, which is made from the elastic side bearing body material in the invention, has the advantages of good fatigue resistance, good mechanical and physical properties and strong elastic recovery capability at low temperature.

Description

technical field

[0001] The invention relates to a component vibration damping material of a railway freight car, in particular to an elastic side support body material of a railway freight car bogie used for manufacturing the elastic side support body of a railway freight car. Background technique

[0002] The elastic side bearing is the key rubber part of the bogie. The elastic side bearing is installed in the side bearing box of the bolster to support the car body, play a supporting and buffering role, improve the rotation constraint between the bogie and the car body and the roll restraint of the car body, and restrain the bogie shaking head and the car body roll The main snake is unstable. Existing rubber materials used to manufacture elastic side bearings have poor physical and mechanical properties, poor elastic recovery ability at low temperature, poor fatigue resistance with metal composite products, and large heat generation of rubber under motion. defect.
