Description
Technical field
This utility model relates to automobile hub bearing technical field, particularly relates to a kind of hub-bearing unit.
Background technology
The Main Function of automobile hub bearing is load-bearing and the rotation offer accurately guiding for wheel hub, and it had both born axle
Bear again radial load to load, be a very important device.Hub-bearing unit be at standard angle contact ball bearing and
Growing up on the basis of taper roll bearing, two sleeves are made and are integrated by it, have that assembling property is good, can omit play
Adjust, lightweight, compact conformation, load bearing capacity big, omission external hub seals and avoids the advantages such as maintenance, is widely used in sedan-chair
Che Zhong, also has the trend progressively expanding application in truck.
According to the requirement of development of automobile, new construction is multi-functional, and to take turns firm bearing unit be inevitable trend, occurs on the market
A lot of novel hub-bearing units, have regulating block location, and control automobile brake etc. with induction system, but due to knot
The reason of structure makes to assemble more complicated, and prefastening load is the best, and sealing function is poor so that its service life reduces a lot,
Cost is the highest.
Summary of the invention
This utility model is for shortcoming of the prior art, it is provided that the hub bearing list that a kind of Stability Analysis of Structures, load are strong
Unit.
In order to solve above-mentioned technical problem, this utility model is addressed by following technical proposals:
A kind of hub-bearing unit, including flange inner ring, flange outer ring, interior snare, ball, retainer, flange inner ring
Outer wall is provided with the outer raceway of two and ball engagement, and flange inner ring puts with inner ring and is respectively provided with the interior rolling corresponding with outer raceway
Road, ball engagement is arranged in retainer, and ball and retainer are located between outer raceway and interior raceway, are provided with two between retainer
End fixes the location bar being connected respectively with retainer, and burr shape is uniform in location is arranged between retainer, and the two ends of location bar set
Projection, retainer is had to be provided with the shrinkage pool being connected with projection.
As preferably, inner ring is set in one end of flange inner ring, and inner ring puts and is provided with through hole, and flange inner ring is provided with screw thread
Hole, inner ring is arranged with the screw running through through hole, and screw is threadeded with screwed hole.
As preferably, being provided with sealing ring between interior snare and flange inner ring, the outside of sealing ring is provided with flange outer ring even
The elastic end cap connect.
As preferably, between flange inner ring and flange outer ring, it is provided with sealing ring.
This utility model, owing to have employed above technical scheme, has significant technique effect: by retainer by location
The position of bar fixed retainer, improves the stability of retainer, when bearing operates, reduces the lateral shear of ball,
Ensure stable operation in ball raceway outside and interior raceway；It is connected by screw between interior snare and flange inner ring, in enhancing
Stability between snare and flange inner ring, it is to avoid inner ring set is shifted over after a protracted use, in causing ball to come off
Raceway, causes potential safety hazard；Flange outer ring arranges elastic end cap, compares sensor end cap cost lower, reduce this skill
The production cost of art.
