Fig. 2 is an enlarged schematic view at a in fig. 1.
Detailed Description
The utility model is further described below with reference to the accompanying drawings: as shown in the figure, a high-service-life suspension ball head comprises a base 1 and a ball pin 2, wherein a ball seat 11 is arranged in the base, one end of the ball pin stretches into the base and is provided with a ball head 21 matched with the ball seat, the ball pin is arranged outside the base, a connecting sleeve 3 used for being connected with a swing arm is sleeved on the ball pin, a first flange 22 is arranged on the circumferential outer wall of the ball pin, a first conical surface 221 is arranged on the circumferential outer wall of the first flange, and a second conical surface 31 in contact with the first conical surface is arranged on the inner wall of the connecting sleeve. The ball pin adopts a conical surface structure, so that stress is dispersed and the service life of the ball pin is prolonged; the design can also improve the stability and reliability of the ball pin, reduce unnecessary faults in the running process of the vehicle and ensure the running safety.
In this embodiment, as shown in the drawing, the cross section of the first flange is isosceles trapezoid with a short side on top. And the mounting is stable.
In this embodiment, as shown in the figure, a cylindrical surface 32 contacting the outer wall of the ball pin is further provided in the connecting sleeve.
In this embodiment, as shown in the figure, the inner wall of the ball seat is provided with a clamping groove 111, and the ball seat further comprises a clamping sleeve 6 for preventing the ball head from falling out, and the circumferential outer wall of the clamping sleeve is installed in the clamping groove. The ball shell structure has the advantages that the clamping sleeve structure is adopted, compared with a traditional ball shell without the clamping sleeve structure, the clamping sleeve structure can seal the gap between the ball shell and the ball body, so that the separation of the ball pin and the shell is prevented, the falling phenomenon can not occur in the running process of the automobile, and the running safety and stability of the automobile are improved. In addition, the cutting sleeve structure can also effectively prevent dust, soil and other sundries from entering the ball head, so that the abrasion and failure occurrence rate of the ball head are reduced, and the service life of the product is prolonged.
