Embodiment Construction

[0012] like figure 1 An automobile ball seat structure is shown, including a ball seat body 1, a "T"-shaped oil groove 2 is arranged on the inner wall of the ball seat body 1, and the inner wall of the ball seat body 1 is in the shape of a spherical arc. The curvature of the outer wall of the ball seat body 1 from the middle to the bottom is smaller than the curvature of the inner wall of the ball seat body from the middle to the bottom.

[0013] Compared with the ball seat of the original structure, this ball seat has added a "T" groove structure. The addition of the "T" groove increases the storage capacity of lubricating oil, which plays an excellent role in lubrication and reduces friction; the ball seat adopts a one-time Forming and integral demoulding technology make the deformation of the inner spherical surface of the ball seat after demoulding and molding extremely small, increase the contact surface between the ball pin and the ball seat, and improve the softness an...

Abstract

The invention discloses an automobile ball seat structure. The automobile ball seat structure comprises a ball seat body, wherein the inner wall of the ball seat body is provided with a T-shaped oil groove, and the inner wall of the ball seat body is in a sphere arc shape. The automobile ball seat structure provided by the invention has the advantages that 1, compared with the ball seat with the original structure, the novel ball seat is additionally provided with the T-shaped groove structure, the lubricating oil storage content is increased because of the T-shaped groove, and thus good effects of lubrication and friction reduction are achieved; 2, a ball seat is once formed and integrally demolded, thus the deformation of the inner spheroidal surface of the ball seat after demoulding formation is small, a contact surface between a ball pin and the ball seat is increased, and the soft stationarity is improved when a spheroidal joint rotates; 3, the ball seat adopts two-section angles, so that the contacting area is increased, and stabilizing and centring effects are achieved, the centring effect enables the device to have excellent self-adaption in-position performance when a ball body center hole in sectioned guiding has certain position angle deviation.

Description

technical field [0001] The invention relates to the technical field of automobile steering systems, in particular to an automobile ball seat structure. Background technique [0002] Suspension system is an important assembly of modern automobiles, which has a great influence on the ride comfort and handling stability of the automobile. Control arm (Control arm, also known as swing arm), as the guiding and force-transmitting element of the automobile suspension system, transmits various forces acting on the wheel to the body, and at the same time ensures that the wheel moves according to a certain trajectory. The control arms elastically connect the wheels and the vehicle body through ball joints or bushes respectively. Among them, the ball seat is an important component of the ball joint. The most important part of the ball joint is the ball seat in the internal structure of the joint, where the ball seat plays a role of sealing and stability. At present, the usual ball s...
