The bottom of the dustproof sleeve is fixed with the fixing plate through the fixing groove, so that the dustproof sleeve is clamped in the ball pin base.
Further, the top of dirt proof boot is equipped with spacing portion and bellying, and the ball round pin includes bulb and toper portion, and the toper portion is equipped with solid fixed ring, and bellying and solid fixed ring phase-match, spacing portion paste tight toper portion, and the elasticity preforming supports spacing portion. The bulge encloses outside solid fixed ring, has blocked the position of dirt proof boot, and the elasticity preforming is pressed in spacing portion, with the dirt proof boot chucking in toper portion.
Further, the elastic pressing piece comprises a pressing portion and a vertical portion from bottom to top, the pressing portion extends outwards from bottom to top and then extends inwards, and the vertical portion is arranged at the top end of the pressing portion. The shape of the pressing part can strengthen the elasticity of the pressing part.
Further, the conical part above the fixing ring is provided with a rough surface. The rough surface of the conical part increases the friction force between the conical part and the dustproof sleeve limiting part, and the dustproof sleeve is prevented from being separated from the ball pin.
Due to the adoption of the technical scheme, the utility model discloses following beneficial effect has:
the top chucking of elastic fixation subassembly with the dirt proof boot is on the ball round pin, therefore the vehicle is through long-time operation back, and the top of dirt proof boot still can compress tightly on the ball round pin, avoids silt to enter into the ball key seat from the gap of dirt proof boot in, prolongs the life-span of outer pull rod bulb. The elastic fixing component compresses the ball pin at the top of the dustproof sleeve through the elastic pressing sheet and is fixed on the ball pin seat through the surrounding rod, and the elastic fixing component is convenient to install and detach. The bottom of the dustproof sleeve is fixed with the fixing plate through the fixing groove, so that the dustproof sleeve is clamped in the ball pin base. The bottom of the dustproof sleeve is fixed with the fixing plate through the fixing groove, so that the dustproof sleeve is clamped in the ball pin base. The bulge encloses outside solid fixed ring, has blocked the position of dirt proof boot, and the elasticity preforming is pressed in spacing portion, with the dirt proof boot chucking in toper portion. The shape of the pressing part can strengthen the elasticity of the pressing part. The shape of the pressing part can strengthen the elasticity of the pressing part.
