The invention relates to a ball socket bush structure connected to an automobile chassis suspension control arm. A hollow ball socket bush is pressed into a cylindrical shell provided with an embedded spherical support in a punching manner. The sway angle of the bush is realized by the opening of the shell and the bush necking design, and the angle of rotating around the shell longitudinally and axially is not limited. Spherical support materials have the features of high compressing resistance and low friction and provide high radial rigidity and low twist rigidity to the ball socket bush, and extreme high radial rigidity is generated by axial punching interference magnitude of the ball socket and the shell. The ball socket structure bush is fine machined by the low-friction and high-compressing-resist materials, locked and sealed and filled with grease, so that a product with the ball socket bush structure has better durability and production conformity as compared with an existing rubber bush.
Description
technical field [0001] The patent of the invention belongs to the connection parts of the automobile chassis structure, specifically a ball and socket bushing structure used for the connection of the suspension control arm of the automobile chassis. Background technique [0002] The existing bushing structure used to connect the suspension control arm of the automobile chassis is mainly a steel sleeve-rubber vulcanized structure, which is press-fitted 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 ...
