Abstract
The utility model discloses an outer ring assembly of a hub bearing of a truck, which comprises a straight top face and an oblique bottom face. In the direction from the first end to the second end of the outer ring assembly, the distance between the top face and the bottom face is gradually reduced. The oblique bottom face and a bulge are utilized by the outer ring assembly of the hub bearing of the truck to jointly define an oblique bearing block rolling path, and precise positioning can be realized under a higher load by using a cylindrical roller bearing with higher stability by combining with the oblique bearing block rolling path.
Description
Technical field
The utility model relates to auto parts and components, relates in particular to the outer coil assembly of the precision positioning that is used for the truck hub bearing.
Background technique
The main effect of hub bearing is load-bearing and for the rotation of wheel hub provides accurate guiding, and it not only bears thrust load but also bear radial load, is very important component.Especially for the hub bearing of truck, because its load of bearing is bigger, so the bearing capacity of hub bearing and measure of precision seem more important.
Traditional hub bearing is combined by two cover tapered roller bearings or ball bearing.For example with reference to shown in Figure 1, Fig. 1 has disclosed a kind of example of traditional hub bearing, has wherein used ball bearing.This hub bearing comprises: outer coil assembly 101, inner ring assembly 102 and ball 103.Form bearing support after wherein outer coil assembly 101 and inner ring assembly 102 merge mutually, in bearing support, hold the structure that ball 103 forms ball bearing.
The hub bearing of this kind structure requires very high to assembly precision, in assembly process, be easy to generate bigger play between outer coil assembly 101 and the inner ring assembly 103, departing from appears in the bearing support that forms after causing merging, and makes ball 103 can't be positioned at the exact position of bearing support.When hub bearing bore bigger load, ball that departs from and bearing support were easy to damage, and cause whole hub bearing the situation of fatigue damage to occur, have a strong impact on working life.
The model utility content
The utility model is intended to propose a kind of outer coil assembly that can realize the truck hub bearing of precision positioning.
According to an embodiment of the present utility model, a kind of outer coil assembly of truck hub bearing is proposed, should comprise the straight end face and the bottom surface of inclination by outer coil assembly, first end of coil assembly is to the direction of second end outside this, and the distance between end face and the described bottom surface reduces gradually.
The outer coil assembly of this truck hub bearing also comprises a projection, and this projection is positioned at first end of outer coil assembly.This projection and bottom surface constitute the upper surface of bearing support raceway.
The bearing support raceway holds roller bearing, and in one embodiment, roller bearing is the cylindrical roller bearing.
The bearing support raceway that bottom surface that the outer coil assembly utilization of truck hub bearing of the present utility model is tilted and projection define inclination jointly, the better columniform roller bearing of stability in use can be realized precision positioning in conjunction with the bearing support raceway that tilts under heavier load.
Description of drawings
Fig. 1 has disclosed the structure of using traditional hub bearing of ball bearing.
Fig. 2 has disclosed the structure according to the outer coil assembly of an embodiment's of the present utility model truck hub bearing.
Fig. 3 has disclosed the truck hub bearing of using outer coil assembly of the present utility model and the structure of truck wheel hub.
Embodiment
With reference to shown in Figure 2, the utility model proposes a kind of outer coil assembly 200 of truck hub bearing, should comprise straight end face 201 and the bottom surface 202 that tilts by outer coil assembly 200, the first end A of coil assembly 200 is to the direction of the second end B outside this, and the distance between end face 201 and the bottom surface 202 reduces gradually.That is to say, this outer coil assembly 200 at the thickness of the first end A greater than thickness at the second end B.Continue with reference to shown in Figure 2, this outer coil assembly 200 also comprises a projection 203, and this projection 203 is positioned at the first end A of outer coil assembly 200.This projection 203 and bottom surface 202 constitute the upper surface of bearing support raceway.
Among Fig. 2 outside the coil assembly 200 that has disclosed the truck hub bearing, also show and the inner ring assembly 300 of outer coil assembly 200 common formation bearing support raceways and the roller bearing 301 that is held by the bearing support raceway, in the embodiment shown in Figure 2, roller bearing 301 is cylindrical roller bearings.The cylindrical roller bearing has better stability.
Fig. 3 has disclosed the truck hub bearing of using outer coil assembly of the present utility model and the structure of truck wheel hub.The truck wheel hub has utilized two truck hub bearings, and the true dip direction of the bottom surface of outer coil assembly wherein is the direction of drawing in towards the central position of truck wheel hub.Thereby make that formed bearing support raceway also is to draw in towards the central position of truck wheel hub, helps carrying greater weight load like this.
The bearing support raceway that bottom surface that the outer coil assembly utilization of truck hub bearing of the present utility model is tilted and projection define inclination jointly, the better columniform roller bearing of stability in use can be realized precision positioning in conjunction with the bearing support raceway that tilts under heavier load.
