Abstract

The invention discloses a hub bearing which comprises inner rings, an outer ring, rolling bodies and retainers. Two first inner channels and two second inner channels are formed in the face, facing the outer ring, of each inner ring, two first outer channels and two second outer channels are formed in the face, facing the inner rings, of the outer ring, and the rolling bodies comprise first rolling balls and second rolling balls. The diameter of the first rolling balls is larger than that of the second rolling balls, the adjacent first rolling balls and second rolling balls share one retainer, the first rolling balls are in point contact with the first outer channels and the first inner channels where the first rolling balls are located, and the second rolling balls are in point contact with the second outer channels and the second inner channels where the second rolling balls are located. Compared with an existing first-generation hub bearing, the hub bearing can bear larger axial force. Due to point contact, the moment generated by the first rolling balls and the second rolling balls during rotation is smaller than that generated by the existing first-generation hub bearing. The hub bearing meets the requirements of the automobile industry for high bearing capacity and low rotating moment on the first generation hub bearing.

Description

technical field [0001] The invention belongs to the technical field of bearings, and in particular relates to a hub bearing. Background technique [0002] Hub bearing is one of the key parts of the car, its main function is to carry weight and provide precise guidance for the rotation of the hub. [0003] Due to the different use environments of wheel hub bearings, there are three types of hub bearings in the market: first-generation hub bearings, second-generation hub bearings, and third-generation hub bearings. The first-generation hub bearings are usually used in some trucks and heavy trucks. The existing generation of hub bearings are usually double-row angular contact ball bearings or double-row tapered roller bearings, including outer rings, inner rings and rolling elements. [0004] With the continuous development of the automobile industry, the performance requirements for the first-generation wheel hub bearings are also constantly upgraded. The existing generation ...
