Abstract

The invention relates to a component damping material for a rail wagon, in particular to a rubber gasket material for a bogie shaft box of the rail wagon, which is applied to a K6 type bogie shaft box. The material comprises the following components in part by weight: 80 to 110 parts of natural rubber, 10 to 30 parts of butadiene rubber, 3 to 8 parts of zinc oxide, 0.5 to 1.5 parts of stearic acid, 0.2 to 2.0 parts of anti-aging agent 4010NA, 0.2 to 2.0 parts of anti-aging agent RD, 0.5 to 2.0 parts of accelerator CZ, 0.3 to 1.0 part of sulfur, 0.5 to 2.0 parts of tetramethylthiuram disulfide (TMTD) serving as an accelerator, 30 to 100 parts of carbon black and 0 to 10 parts of plasticizer. The rubber gasket material for the bogie shaft box of the rail wagon has the advantages of meeting the basic requirements of elastic supporting and elastic damping, greatly improving intensity, fatigue resistance and permanent deformation resistance, prolonging service life and adapting to a larger application temperature range.

Description

technical field [0001] The invention relates to a component vibration damping material of a railway freight car, in particular to a rubber pad material for the axle box of a railway freight car bogie of the Zhuan K6 type bogie. Background technique [0002] The inner splayed rubber elastic shear pad installed in the axle box of Zhuan K6 bogie is used to realize the elastic positioning of the wheel set, reduce the unsprung mass of the bogie, and isolate the high-frequency vibration between the wheel and the rail. The rubber material used in the existing axle box rubber has defects such as low strength, poor fatigue resistance and permanent deformation resistance, and low service life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rubber pad material for the axle box of a railway truck bogie with high strength, fatigue resistance, strong permanent deformation resistance and long service life. [0004] The rail...
