Wheel bearing structure with gasket

Abstract

The invention discloses a wheel bearing structure with a gasket, which relates to the field of automobile parts and comprises a flange plate and the like, an inner ring is mounted on the flange plate in a clamping groove manner, an outer ring is sleeved on the flange plate, an inner raceway is arranged between the inner ring and the outer ring, an outer raceway is arranged between the journal root of the flange plate and the outer ring, and the inner raceway and the outer raceway form a double-row raceway; a spin riveting outer diameter is arranged on the side, close to the inner ring, of the flange plate, and a gasket is riveted to the spin riveting outer diameter through the spin riveting technology. A shaft hole is formed in the center of the gasket for a driving wheel spline half shaft to penetrate, and a flange is arranged along the outer edge of the gasket; at least three protruding points are evenly distributed on the flange along the circumference, and the protruding points are matched with a concave area on the outer diameter of the spin rivet to form a lock catch type structure. The technical problem that the vehicle performance is reduced due to the fact that the hardness of the surface, attached to the constant-speed half shaft, of the wheel bearing is insufficient can be solved; and meanwhile, the technical problem of abnormal sound of the vehicle caused by insufficient wear resistance of the surface, attached to the constant-speed half shaft, of the wheel bearing is solved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a wheel bearing structure with gaskets. Background technique [0002] In the prior art, in order to maintain the good reliability of the product in the manufacturing process of the wheel bearing, a spin riveting process is generally used for the flange. However, the implementation of the spin riveting process requires that the hardness of the spin riveting part is generally not higher than 280HB. Therefore, in the prior art, the contact between the wheel flange and the spline half shaft of the constant velocity drive wheel often has the following problems: [0003] 1. The hardness of the flange riveting part is insufficient. After a period of use, the surface of the material is plastically deformed and severely worn, which leads to the attenuation of the preload of the center nut of the constant-velocity drive wheel and the decline in vehicle performance; [0004] 2. When the vehicle ...
