Abstract
The utility model relates to an automobile wheel hub bearing unit, which belongs to the field of automobile parts and components. The prior automobile wheel hub bearing unit has the defect that a bearing outer ring easily does axial movement so that influence the service life. The automobile wheel hub bearing unit comprises a seat ring, a bearing seat and a double-row angular contact ball bearing; the bearing seat consists of a ring flange and a bearing installation shaft which are connected together; a bearing installation cavity is arranged in the seat ring; an outer ring shoulder supporter is arranged at the end part of the bearing installation cavity, which is close to the ring flange; an outer ring of the double-row angular contact ball bearings is of integral type; the outer ring is embedded in the bearing installation cavity of the seat ring; the axial length of the bearing installation cavity is less than that of the outer ring; one end of the outer ring props against the outer ring shoulder supporter, while the other end extends out of the outer ring; and when the automobile wheel hub bearing unit is used, the outer ring props against a chassis for axial spacing to effectively avoid axial movement of the outer ring, thereby improving the service life of the bearing unit.
Description
Technical field
The utility model belongs to the auto parts and components field, and is especially relevant with a kind of automobile hub bearing.
Background technique
Existing a kind of automobile hub bearing mainly is made up of seat ring, bearing support and bearing, and bearing support is made up of flange plate that is connected as a single entity and Bearing Installation axle, and Bearing Installation axle outer wall is provided with inner ring by shoulder near flange plate one side; Be provided with the Bearing Installation chamber in the seat ring, the Bearing Installation chamber is provided with the outer ring by shoulder for one section; Bearing is a double-row angular contact bal bearing, and bearing inner race is made up of two little inner rings, and two little inner rings are set in the Bearing Installation axle, and an end end face of one of them little inner ring is resisted against described inner ring by the shoulder axial limiting; Bearing outer ring is an integrated type, the outer ring is flush-mounted in the Bearing Installation chamber in the seat ring, outer ring and seat ring inwall form interference fit, one end is resisted against described outer ring by the shoulder axial limiting, seat ring is installed on the automobile chassis and fixes with car body during use, the outer ring the other end is equal with the seat ring end face, and seat ring end face and cycle surface are resisted against the chassis and by the chassis bearing outer ring are carried out axial limiting.After such automobile hub bearing uses a period of time, thereby outer ring loosening easily generation in the Bearing Installation chamber of seat ring moves axially, and the outer ring is damaged easily, influences the working life of bearing unit.
The model utility content
The utility model purpose is exactly will solve bearing outer ring that above-mentioned automobile hub bearing exists to be easy to generate and to move axially and influence the defective in working life, provides a kind of bearing outer ring of effectively avoiding to produce axially movable automobile hub bearing.For this reason, the utility model is by the following technical solutions:
A kind of automobile hub bearing comprises seat ring, bearing support and double-row angular contact bal bearing, and bearing support is made up of flange plate that is connected as a single entity and Bearing Installation axle, and Bearing Installation axle outer wall is provided with inner ring by shoulder near flange plate one side; Be provided with the Bearing Installation chamber in the seat ring, the Bearing Installation chamber is provided with the outer ring by shoulder near described flange plate one end end; Described double-row angular contact bal bearing inner ring is made up of two little inner rings, two little inner rings are set in the Bearing Installation axle, one end end face of one of them little inner ring is resisted against described inner ring by shoulder, the double-row angular contact bal bearing outer ring is an integrated type, the outer ring is flush-mounted in the Bearing Installation chamber in the seat ring, one end is resisted against described outer ring by shoulder, and it is characterized in that: described Bearing Installation chamber axial length is less than described outer ring axial length, and the described outer ring the other end stretches out seat ring.
When the utility model used, seat ring was installed on the automobile chassis and fixes with car body, and outer ring the other end end face is resisted against the chassis and by the chassis bearing outer ring is carried out axial limiting.
Use the utility model can reach following beneficial effect: because Bearing Installation chamber axial length is less than the bearing outer ring axial length, have only the outer ring to be resisted against the chassis during use and carry out axial limiting, can effectively avoid the outer ring to produce and move axially, thus the working life of having improved bearing unit.
