Connecting rod of transverse stabilization rod and machining process of ball pin assembly

Abstract

The invention discloses a processing technology of a connecting rod of a horizontal stabilizer bar and a ball pin assembly. The connecting rod of the horizontal stabilizer bar includes: a ball pin seat assembly, and the ball pin seat assembly has an intermediate connecting rod and a ball pin assembly. Pin seat; bushing, the bushing is installed in the ball pin seat and has a spherical installation cavity; ball pin assembly, the ball pin assembly includes a ball pin and a ball pin rod, the ball pin and the ball pin The ball pin rod is fixedly connected and hinged to the installation cavity, and the end of the ball pin away from the ball pin rod is a spherical surface. The connecting rod of the stabilizer bar according to the embodiment of the present invention can keep the contact area between the ball pin and the bushing unchanged by arranging a spherical ball pin to prevent the bushing from being worn out. The moment of the connecting rod is stable during the swing process and the working performance good.

Description

technical field [0001] The invention relates to a processing technology of a connecting rod of a lateral stabilizer bar and a ball pin assembly. Background technique [0002] When the vehicle is driving on an uneven road in a straight line or when turning, the wheels on the left and right sides are at different heights, and the vehicle body will roll laterally. . The stabilizer bar is fixed on the left and right hanging lower brackets or shock absorber struts through connecting rods, and the connecting rods are mostly assembled through the ball pin structure. In the related technology, the processing technology of the ball pin assembly is: raw material, cold heading, rolling Silk, turning (rough turning, fine turning), tumbling, cleaning. [0003] The end of the ball pin has a cross-section because it is difficult to achieve a complete spherical shape by machining, so that the contact area between the ball pin and the bush becomes smaller due to the cross-section during th...

Problems solved by technology

[0003] The end of the ball pin has a cross-section because it is difficult to achieve a complete spherical shape by machining, so that the contact area between the ball pin and the bush becomes smaller due to the cross-section during the swing of the ball pin in the bush, the wear of the bush is accelerated, and the connecting rod Reduced service life

In addition, there are many processes and complex mold structure in the cold heading process of the ball pin blank; in the ball pin turning process, due to the complex structure and the large machining allowance of the blank, two turnings (rough turning and fine turning) are required to complete the processing and production efficiency. Low cost, much waste of raw materials; it is not easy to ensure the roundness of the two poles when the ball end of the ball pin is machined, the roughness is not easy to guarantee during the rolling process of the ball pin, and the rolling pressure is not easy to adjust, and the rolling wheel is easy to damage
