Abstract

The invention discloses a rubber composition for a leaf spring lug bushing for an automobile. The rubber composition is characterized by comprising the following components in parts by weight: 100 parts of rubber, 1.5-3 parts of a p-phenylenediamine type anti deteriorant, 1.5-3 parts of a hydrogenated quinoline type anti deteriorant, 3-5 parts of microcrystalline wax, 5-8 parts of an active agent, 1-2 parts of stearic acid, 3-6 parts of resin, 3-5 parts of a processing addition agent, 5-8 parts of a slipping agent, 3-5 parts of a fatty oil plastifier, 5-10 parts of a petroleum plastifier, 60-95 parts of carbon black, 1.5-2.1 parts of an accelerant, and 1.5-1.8 parts of a vulcanizing agent. Through the adoption of the rubber composition disclosed by the invention, the lubricating property between the lug bushing and a bearing is improved, the friction noise is reduced, and the abrasion resistance is improved, so that the lug bushing is not invalid under the long-term use state, under the circumstance that the cost is not increased, the fabrication process is simple, and the lug bushing is convenient to use and mount.

Description

Technical field [0001] The invention relates to a rubber composition of a leaf spring lug bushing for automobiles, and belongs to the technical field of rubber chemicals. Background technique [0002] Automobile leaf spring lug bushing such as figure 1 As shown, the leaf spring lug bushings used in minivans and trucks are indispensable vibration damping and buffering parts. In the course of its use, especially on bumpy roads after loading, the lug bushings are carrying the deformation and wear of the extrusion force given in different directions. Many car owners often use the lug bushings when they use 2000 kilometers. The squeeze failure and damage caused the vehicle chassis to squeak abnormally during driving, and the vibration damping and cushioning effects also failed. Summary of the invention [0003] The invention aims to solve the technical problems that the existing automobile leaf spring lug bushing has poor extrusion resistance and is prone to failure and damage.
