Straight ball base of V-type track bar assembly

Abstract

A straight ball seat of a V-shaped thrust rod assembly, which includes a straight ball seat body formed by forging and finishing, with a cylindrical through hole of a spherical pin in the middle, and the inner end of one side of the cylindrical through hole of the straight ball seat body is machined There is a convex ring used for the stop of the spherical pin, and the inner end of the other side is processed with a groove for the retaining ring to be embedded for positioning and fixing the spherical pin. The cylindrical connection end is processed with a reduced-diameter cylindrical connection section, and a connection pipe is sleeved on the reduced-diameter cylindrical connection section and is integrated by friction welding; the thickness of the straight ball seat body is greater than that of the cylindrical The diameter of the connecting end, the outer circular wall surface of the straight ball seat body is an oblique annular surface with a convex ring in the middle and gradually shrinks to the two ends; it has a reasonable structure, convenient processing and manufacturing, and a tubular The connection fastness of the shaft is strong, the production efficiency is high, and the use is safe and reliable.

Description

technical field [0001] The invention relates to a straight ball seat of a V-shaped thrust rod assembly, especially a straight ball seat suitable for a V-shaped thrust rod assembly used in the balance rear suspension of heavy tractors and trucks, belonging to the V-shaped thrust rod Assembly technology field. Background technique [0002] The V-shaped thrust rod assembly plays a role that cannot be ignored on heavy-duty trucks. In addition to preventing the front and rear displacement of the middle and rear axles, it can also prevent left and right movement. Therefore, when the truck is overloaded, the V-shaped thrust rod can absorb the impact The load is effectively and evenly distributed to the longitudinal beams on both sides of the body, reducing the impact on the axle housing and chassis. [0003] The traditional V-shaped thrust rod assembly is mainly composed of upper ball seat, straight ball seat, spherical pin assembly and other components. Due to the irregular oute...
