Problems solved by technology

The design of rubber bushings generally has more freedom to choose the shape of rubber parts, and the stiffness ratio in three directions (axial, radial, torsional) can be properly selected. The failure mode of ordinary rubber bushings is mainly manifested as wear and fatigue. Cracks, aging, plastic deformation and stiffness changes, etc., so the service life of the existing rubber bushings on the market is short, and for rubber bushings, even if the structure is the same, the rubber formula is different. The process is different, and the products produced are also obviously different.

Abstract

The invention discloses a bushing rubber for a guiding device of an automotive suspension system and a manufacture method of a rubber bushing. The bushing rubber in the guiding device for the automotive suspension system comprises the following components based on the total weight: 40 to 60% of natural rubber, 1 to 5% of zinc oxide, 1 to 5% of active auxiliary, 1 to 5% of composite vulcanizing agent, 20 to 30% of carbon black, 5 to 10% of plasticizer, and 1 to 5% of plastic age resister. According to the bushing rubber for the guiding device of the automotive suspension system, the rubber formula is improved, so that the resistance to wear, fatigue crack, aging, plastic deformation and stiffness change and the like are improved; and a test shows that the rubber made according to the formula and a bushing manufactured according to the method are characterized in that the rubber hardly falls from an inner steel pipe.

Description

technical field [0001] The invention relates to a bushing rubber used in a guide device of an automobile suspension system and a manufacturing method of the rubber bushing. Background technique [0002] Rubber bushing has become an indispensable and important component in automobiles because of its good vibration isolation performance, expected elastic characteristics and attenuation characteristics. Reasonable design of the size and performance of the rubber bushing can ensure that the vehicle has good handling stability and smoothness. The design of rubber bushings generally has more freedom to choose the shape of rubber parts, and the stiffness ratio in three directions (axial, radial, torsional) can be properly selected. The failure mode of ordinary rubber bushings is mainly manifested as wear and fatigue. Cracks, aging, plastic deformation and stiffness changes, etc., so the service life of the existing rubber bushings on the market is short, and for rubber bushings, e...
