Ball head assembly with compensation structure and manufacturing tool and assembling method of ball head assembly

Abstract

The invention provides a ball head assembly with a compensatory structure. The ball head assembly includes a ball shell, and an installation cavity with the open top is formed on the ball shell; a ball base is installed at the upper end of the installation cavity, the ball base is spherical, and a spherical cavity is formed between the ball base and the installation cavity; a ball pin includes a ball body and a pin rod; the open end of the ball shell is bent inward in the radial direction to form a pressed edge, an installation part is formed between the lower bottom surface of the pressed edge and the upper end face of the ball base, and the installation part is internally and sequentially provided with a sealing plate, a compensating gasket and an elastic part from up to bottom. According to the ball head assembly with the compensatory structure, the compensating gasket is additionally arranged, through the deformation of the compensating gasket, accumulative errors produced by otheraccessories are compensated, the consistency of the compression amount of a belleville spring is ensured, the stability of the torque of a product is achieved, the quality reliability and use reliability of the product are greatly improved, and the use safety is improved.

Description

technical field [0001] The invention relates to an automobile ball head, in particular to a ball head assembly with a compensation structure, a manufacturing tool and an assembly method thereof. Background technique [0002] The ball joint assembly is widely used in independent suspension systems, and the control arm or thrust rod is usually connected to other components through the ball stud pin at the end. The main function of the ball joint assembly is to realize the wheel bouncing up and down and steering movement. It is mainly composed of end cover, ball pin, ball seat and dust cover, etc. The end cover is mostly made of steel stamping parts, and its material is mainly carbon steel, and some are also made of aluminum alloy or ductile iron. The processing accuracy of the ball pin surface is high, and the alloy steel with good hardenability is mostly used. The surface of the ball pin matched with the metal ball needs to be surface hardened by high-frequency quenching to ...

AI Technical Summary

Problems solved by technology

However, in the actual production process, since there are machining errors in the dimensions of the ball seat, ball shell and ball pin, the cumulative error of the three parts tends to make the torque of the product very unstable, thereby reducing the reliability of product quality and reliability. Sex, there are certain safety hazards in the process of use
