Problems solved by technology

At present, the deformation of the inner and outer spherical surfaces of the usual ball seat is relatively large, so the contact surface between the ball pin and the ball seat becomes smaller, and the softness and stability of the ball joint during rotation are poor.

Embodiment Construction

[0012] Such as Figure 1 ~ Figure 2 A ball joint structure for a passenger car is shown, including a ball pin 1, a ball seat 2, a rear cover 3, a dust cover 4, a joint 5, and a washer 6, and the washer 6 is arranged under the ball seat 2, and the joint 5 Socketed outside the ball seat 2 and the washer 6, the joint 5 is equipped with a back cover 3 covering the washer 6, the ball pin 1 includes a vertebral body, a connecting rod end connected to the two ends of the vertebral body, and a ball end surface, and the ball pin 1 The ball end surface of the ball is connected in the ball seat 2, the dust cover 4 is clamped on the joint 5 through the collar 7, the ball seat 2 is a split structure composed of two hemispherical seats, and the two hemispherical seats are connected by an arc Arm 8 is connected.

[0013] The dust cover 4 is sleeved on the vertebral body of the ball pin 1 . The structure of the ball seat adopts the technology of split left and right, the center of the botto...

Abstract

The invention discloses a ball connector structure for a passenger car. The ball connector structure comprises a ball pin, a ball base, a rear cover, a dustproof cover, a connector and a gasket. The gasket is arranged below the ball base, the connector is in sleeved connection outside the ball base and the gasket, the rear cover which covers the gasket is arranged on the connector, the ball pin comprises a conical body, connecting rod ends at the two ends of the conical body and a ball end face, the ball end face of the ball pin is connected in the ball base, the dustproof cover is in clamped connection to the connector through a clamping ring, the ball base is of a splitting structure formed by connecting two hemispherical bases, and the two hemispherical bases are connected through an arc-shaped connecting arm. By the adoption of the structure, the structure has the advantages that left-and-right splitting is adopted in the structure of the ball base, the centers of the bottoms of the hemispherical bases are in arch-shaped linkage, and formed integrally, the whole demoulding technology is adopted, the deformation amount, generated after the demoulding forming, of the inner and outer ball-shaped surfaces of the ball base is smaller, the contact area of the ball pin and the ball base is increased, and when the ball connector rotates, the soft stability of the ball connector is improved.

Description

technical field [0001] The invention relates to the technical field of automobile steering, in particular to a ball joint structure for passenger vehicles. Background technique [0002] The control arm transmits forces and moments between the wheel (or axle) and the frame (or body) and determines how it is connected. There are two types of connectors: shaft pin joint and ball stud type. Here we mainly introduce the ball stud type ball joint. Control arms usually have joints at their ends to connect to other pieces. [0003] The ball joint is composed of a ball pin, a ball seat, a back cover, a gasket, a joint, a dust cover, and a collar. Spherical diameter, after the ball joint structure is assembled as required, the forced deformation of the plastic ball seat will generate an internal force that always tightens the ball pin upwards, so that the ball pin and the ball seat maintain a good fit. One of the most important parts in a ball joint is the ball seat in the internal...
