Abstract
The utility model discloses a novel hub bearing, which comprises a hub bearing outer ring, a hub bearing inner ring and a seal ring assembly. A plurality of threaded holes connected with a steering knuckle are arranged all around the hub bearing inner ring; a tapered roller, a retainer and the seal ring assembly are arranged between the bearing inner ring and the bearing outer ring; and the threaded holes are not circumferentially and uniformly distributed and arranged. In the utility model, the hub bearing outer ring is provided with the seal ring assembly used for forming a sealing area. By adopting the novel hub bearing, larger space is brought to the design of a rim assembly, all parts of a rim are more reasonably arranged and simultaneously, the strength of the rim assembly is enhanced.
Description
Technical field
The utility model relates to the hub bearing that vehicle uses.
Background technique
In the prior art, often use two generation bearing mounting hole all be that 3 holes or 4 holes are uniform, this type of hub bearing is applicable to on the more abundant vehicle of installing space.And if the vehicle of design space on arranging is not abundant, then need to change the layout of bearing mounting hole.
Summary of the invention
The purpose of this utility model is to design for the less vehicle of wheel hub installing space, proposes the hub bearing that a kind of mounting hole is a non-uniform Distribution.
The utility model is made of hub bearing outer ring, hub bearing inner ring and seal ring assembly.Be provided with a plurality of tapped holes that are connected usefulness with knuckle around the hub bearing inner ring, be provided with tapered roller and retainer and seal ring assembly between bearing inner race and bearing outer ring, a plurality of tapped holes are the on-circular layout that evenly distributes.
Hub bearing described in the utility model outer ring is provided with in order to form the seal ring assembly of sealing area.
Tapped hole number described in the utility model is 4, and the circumference angle that forms between tapped hole is respectively 120 degree, 85 degree, 70 degree and 120 degree.
The utility model has brought bigger space for the design of wheel limit assembly, and it is more reasonable to make that each component of wheel limit are arranged, has improved the intensity of wheel limit assembly simultaneously.
Description of drawings
Can be by detailed description to the purpose of this utility model below in conjunction with accompanying drawing, feature and advantage have clearer understanding.
Fig. 1 is the utility model embodiment's a forward axonometric drawing;
Fig. 2 is the utility model embodiment's an installation tapped hole hole bitmap.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Present embodiment is made of hub bearing outer ring 4, hub bearing inner ring 2 and seal ring assembly 1.Be provided with the seal ring assembly 1 of dustproof effect on the hub bearing outer ring 4, sealing assembly 1 cooperates the formation sealing area with wheel hub.Be provided with 4 tapped holes 3 that are connected usefulness with knuckle around the hub bearing outer ring 4.4 tapped holes are the on-circular layout that evenly distributes, and the circumference angle of formation is respectively 120 degree, 85 degree, 70 degree and 120 degree.Be provided with bearing inner race 2 by centerline.Between bearing inner race 2 and bearing outer ring 4, be provided with tapered roller and retainer and seal ring assembly 5.
The circumference angle of the tapped hole in the utility model can be arranged to other number of degrees according to the layout needs.According to the size that axle carries, configuring needs just can carry out position, hole layout behind several mounting holes, and the layout of position, hole can guarantee that preferably left and right sides hub bearing is a same pieces.
