Abstract

The invention discloses a spring bushing assembly for automobile front steel plates, and a production process thereof. The production process comprises the steps of fixing rubber on an inner bushing to form a rubber assembly, squeezing the rubber assembly into an outer bushing so as to reduce the diameter of the rubber assembly, reducing the diameter of the assembly outer bushing (including the rubber assembly), turning the assembly around, reducing the diameter again, finishing and processing the length of the outer bushing, shaping bound circular-arc shape mouths at two ends of the assembly, and the like. The spring bushing assembly can completely meet the requirement of automobiles on life span, and has the advantages of high strength, excellent vibration reducing effects and fatigue resistance.

Description

technical field [0001] The invention relates to an automobile front leaf spring bushing assembly and a production process thereof, and more specifically belongs to the field of automobile parts. Background technique [0002] Due to the very low service life of the currently used front leaf spring bushing assembly, rubber cracking often occurs shortly after use, and the compression stiffness and torsional stiffness cannot meet the needs of trucks. Damage to the bushing assembly will cause great harm to the car. , Not only affects the shock absorption performance of the car, but also the noise is very loud. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a front leaf spring bush assembly of an automobile, which solves the above problems and provides a bush assembly for the front leaf spring of a truck. [0004] An automobile front leaf spring bushing assembly of the present invention comprises an inner sheath...
