Abstract

The invention discloses an end face spline type hub bearing unit, and relates to the field of hub bearings. The end face spline type hub bearing unit comprises an outer ring, an inner ring, a flange plate and an end face spline, an outside roller path is arranged between the shaft neck root of the flange plate and the outer ring of a hub bearing, the outside roller path and an inside roller path arranged between the inner ring and the outer ring form a double roller path, a roll rim is arranged at the side, close to an inner side sealing ring, of the flange plate, and the end face spline is arranged on the side end face and used for being directly connected with a drive shaft. The end face spline type hub bearing unit has the beneficial effects that the end face spline of the hub bearing unit can be connected with the drive shaft, is used as a transmission device for torque transmission to lift a drive torque, and compared with existing inner spline transmission, torque driving is obviously improved; the full vehicle NVH performance is effectively improved, the disassembly and disassembly convenience in the full vehicle production and maintenance process is improved, the weight ofthe hub bearing is reduced, and light weight is realized; and the hub bearing with end face spline teeth can effectively eliminate drive clearances, and eliminate drive abnormal sound.

Description

technical field [0001] The invention relates to the field of hub bearings, in particular to an end face spline type hub bearing unit. Background technique [0002] Hub bearings are automotive components that carry weight and provide precise guidance for the rotation of the hub. With the rapid development of the automobile industry, traditional hub bearings have been gradually eliminated due to the difficulty of assembly, high cost, poor reliability, low torque transmission efficiency, and abnormal drive noise. At present, there is an urgent need for a rationalized assembly process , Lightweight and miniaturized new hub bearing unit structure. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide an end face spline type hub bearing unit, which has the advantages of compact structure, high installation accuracy, long service life, stable power transmission, good sealing performance and excellent...
