Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a calibration device for an automobile half shaft sleeve. Background Technique

[0002] The half shaft sleeve is an important part on the automobile drive axle assembly. It forms an integral body with the drive axle housing, fixes the axial relative positions of the left and right drive wheels, supports the mass of the frame and each assembly thereon together, and bears the road surface reaction force and torque transmitted from the wheels during the driving of the automobile and transmits them to the frame through the suspension. However, in the actual use process, due to the large weight of the automobile half shaft, it is difficult to adjust it during docking, and the operation difficulty is great.

[0003] The authorized patent with the application number of 202120931858.5 includes a positioning sleeve. Multiple connecting bars are fixed on the end face of the positioning sleeve; multiple fixing holes are radially formed in the positioning sleeve, and multiple sliding sleeves are fixedly connected in the fixing holes. An elastic member is slidably arranged in the sliding sleeve, and an arc-shaped gasket is fixed at the inner end of the elastic member. An arc-shaped groove corresponding to the arc-shaped gasket is arranged inside the fixing hole, so that the arc-shaped gasket can be received into the arc-shaped groove; the front end of each connecting bar is fixedly penetrated with a threaded tube, and an adjusting member is threadedly connected in the threaded tube, which is convenient to adjust the position of the half shaft sleeve from all directions.

[0004] The above comparative document has the following problems:

[0005] Only limiting the arc-shaped gasket by the elastic force of the spring will cause the problem of poor positioning stability of the arc-shaped gasket for the rear axle shaft, and there is no function of limiting the threaded rod. When the adjusting block positions the half shaft sleeve, the threaded rod is prone to misrotation, which in turn causes the movement of the adjusting block, thus affecting the positioning effect of the adjusting block on the half shaft sleeve.

[0006] Therefore, we make improvements and propose a calibration device for an automobile half shaft sleeve. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:
