Abstract
The utility model discloses a truck hub, which comprises a hub body, hub bearings and inner space ring, wherein the hub bearing is arranged in the hub body; each hub bearing comprises outer ring assemblies, inner ring assemblies and roller bearings. Each outer ring assembly comprises a straight first top face and an oblique first bottom face; in the direction from the first end to the second end of the outer ring assembly, the distance between the first top face and the first bottom face is gradually reduced. Each inner ring assembly comprises a straight second bottom face and an oblique second top face; in the direction from the first end to the second end of the inner ring assembly, the distance between the second top face and the second bottom face is gradually increased, wherein the first bottom face and the second top face are parallel, and the first bottom faces and the second top faces jointly form bearing block rolling paths. The roller bearings are arranged in the bearing block rolling paths. The inner space ring is sheathed onto the hub bearings.
Description
Technical field
The utility model relates to auto parts and components, relates in particular to the truck wheel hub with precision positioning ability.
Background technique
Wheel hub is important automobile component.The parts of most critical are hub bearings in the wheel hub.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 truck wheel hub, can realize precision positioning and can carry bigger load.
According to an embodiment of the present utility model, a kind of truck wheel hub is proposed, comprising: hub body, hub bearing and cone spacer.Hub bearing is installed in the hub body, and hub bearing comprises: outer coil assembly, inner ring assembly and roller bearing.Outer coil assembly comprises first straight end face and first bottom surface of inclination, and first end of coil assembly is to the direction of second end outside this, and the distance between first end face and described first bottom surface reduces gradually.Inner ring assembly comprises second straight bottom surface and second end face of inclination, from first end of this inner ring assembly direction to second end, distance between second end face and described second bottom surface increases gradually, wherein this first bottom surface is parallel with second end face, and first bottom surface and second end face constitute the bearing support raceway jointly.Roller bearing is installed in the bearing support raceway.Cone spacer is sleeved on the hub bearing.
In one embodiment, outer coil assembly comprises a projection, and this projection is positioned at first end of outer coil assembly.The projection and first bottom surface constitute the upper surface of bearing support raceway.
In one embodiment, inner ring assembly also comprises first limiting stopper and second limiting stopper, and first limiting stopper is positioned at first end of inner ring assembly, and second limiting stopper is positioned at second end of inner ring assembly.Second end face between first limiting stopper and second limiting stopper constitutes the lower surface of bearing support raceway.
In one embodiment, roller bearing is the cylindrical roller bearing.
In one embodiment, the true dip direction of bearing support raceway is the direction of drawing in towards the central position of hub bearing.The true dip direction of roller bearing also is the direction of drawing in towards the central position of hub bearing.
In one embodiment, the truck wheel hub comprises two symmetrically arranged hub bearings.
Face, projection and the limiting stopper that the outer coil assembly of the hub bearing of truck wheel hub of the present utility model and inner ring assembly utilization are tilted defines the bearing support raceway of 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.This truck wheel hub can adopt two symmetrically arranged hub bearings, increases the heavy burden ability.
Description of drawings
Fig. 1 has disclosed the structure of using traditional hub bearing of ball bearing.
Fig. 2 has disclosed the structural drawing according to an embodiment's of the present utility model truck wheel hub.
Fig. 3 has disclosed the structural drawing according to hub bearing in an embodiment's of the present utility model truck wheel hub.
Embodiment
With reference to shown in Figure 2, the utility model proposes a kind of truck wheel hub 200, comprise hub body 202, hub bearing 300 and cone spacer 204.Hub bearing 300 is installed in the hub body 202.Cone spacer 204 is sleeved on the hub bearing 300.
With reference to shown in Figure 3, hub bearing 300 comprises outer coil assembly 302, inner ring assembly 304 and roller bearing 306.
Roller bearing 306 is installed in the above-mentioned bearing support raceway.In one embodiment, for stability and the bearing capacity that improves roller bearing, use columniform roller bearing.
With reference to shown in Figure 2, the true dip direction of bearing support raceway is the direction of drawing in towards the central position of hub bearing.So the roller bearing that is placed on wherein also is to draw in towards the central position, helps carrying greater weight load like this.Same with reference to shown in Figure 2, this truck wheel hub 200 comprises two symmetrically arranged hub bearings 300.
Face, projection and the limiting stopper that the outer coil assembly of the hub bearing of truck wheel hub of the present utility model and inner ring assembly utilization are tilted defines the bearing support raceway of 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.This truck wheel hub can adopt two symmetrically arranged hub bearings, increases the heavy burden ability.
