Abstract

The invention relates to a ball socket sleeve connected with an automotive suspension control arm and is characterized in that a hollow ball socket sleeve is pressed into a columnar casing embedded with a spherical support in a stamping manner, the oscillation angle of a casing pipe is determined by the opening of the columnar casing and the neck of the casing pipe, and the rotation angle of the casing pipe around the ordinate axis of the columnar casing is not restricted. The material of spherical support has the characteristics of high pressure resistance and low friction and provides relatively high radial stiffness and low torsional stiffness to the ball socket casing pipe, and the axial stamping interference magnitude of a ball socket and the columnar casing generates great axial stiffness. The ball socket sleeve is made of a low-friction and high-strength material through fine machining, and through locking, sealing, lubricating grease filling, the durability and conformity of production of ball socket sleeve products is superior to rubber sleeves in the prior art.

Description

technical field [0001] The patent of the invention belongs to the structural connection parts of the automobile chassis, specifically a ball-and-socket bush used for the connection of the suspension control arm of the automobile chassis. Background technique [0002] The existing bushing used for connecting the control arm of the suspension of the automobile chassis is mainly a steel sleeve-rubber vulcanized structure, which is pressed into the swing arm structure by interference fit. The stiffness in the axial, radial and torsional directions is provided by the rubber compression, but due to the inherent characteristics of the rubber, the torsional angle is usually less than 25°, and the stiffness in the three directions affects each other. With the increase of the axial and radial stiffness, the torsional stiffness index The increase has an inverse trend to the torsion angle. At present, the pursuit of comfort in cars is usually achieved by increasing the torsional stroke...
