[0002] The function of the automobile thrust rod is to prevent the automobile axle from shifting. The general straight thrust rod is used to prevent the front and rear axles from shifting forward and backward, while the new thrust rod is used to prevent the axle from shifting left and right. Due to the layout of the vehicle, the axle end can only adopt a shell structure. When the car turns, the axle shifts left and right to a large extent, causing the shell end to break. In severe cases, it will cause premature tire wear or even a serious accident such as a tire blowout. How to ensure the normal operation of the shell end without breaking is a technical problem that the existing thrust rod assembly needs to overcome. Utility Model Content

[0005] Furthermore, a fixed tube structure is provided at the fixed end of the shell, a notch is axially opened on the side wall of the fixed tube structure, and clamping plates with holes are respectively provided on both sides of the notch. The two clamping plates are clamped by bolts and nuts to fix the fixed tube structure to the end of the rod body.

[0006] Furthermore, the middle portion of the rod body is bent, and the angle of the bent portion of the rod body is greater than 170°.

[0007] Furthermore, the other end of the cone pin of which the spherical structure is arranged at one end is provided with an external thread, and a nut is screwed through the external thread.

[0008] Furthermore, hollow mounting holes are respectively provided at both ends of the cone pin of the middle portion of the spherical structure.

[0009] Furthermore, the shell and the fixing tube structure are formed by welding or integral casting.

[0010] Furthermore, the outer side walls of the fixed cylinder structures on each side are respectively provided with multiple circles of annular protruding structures.

[0011] Through the above arrangement, the utility model optimizes and improves the structure of the tapered pin, that is, a spherical structure is provided at one end or the middle part of the tapered pin, a plurality of concave annular grooves are provided on the periphery of the spherical structure, an annular rubber sleeve is sleeved on the periphery of the annular groove of the spherical structure, the spherical structure of the tapered pin is located in the annular cavity of the outer shell, one end opening of the annular cavity is covered with a hole retaining ring for clamping the rubber sleeve, and in addition, the tapered pin is made of high alloy material and is heat-treated, and the stress-bearing part of the outer shell is strengthened.
