In the top sealing structure, the rubber sealing ring is positioned on the side close to the center of the car body and the circular metal ring framework is positioned close to the roll ball side of the boss bearing unit. The circular metal shell is made of spring steel.
Description
Technical field
The utility model relates to a kind of hub-bearing unit, and specifically sealing configuration on the spring steel skeleton of third generation hub-bearing unit belongs to automobile technical field.
Background technique
The Main Function of automobile 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 a very important device.The structure of conventional wheel hub bearing unit as shown in Figure 4, comprise flange plate for stationary hub, be fixed on the vehicle frame and and the outer ring of flange plate coupling, be installed in ball between outer ring and the flange plate, be used for the inner ring spacing to described ball, and for the upper black box 9(ring-type with the space sealing between outer ring and the flange plate, with sensor) and lower seal assembly (ring-type).Described inner ring is set on the flange plate, prevents the ball slippage out; Described upper black box and lower seal assembly are installed in respectively the two ends of outer ring, and the space-filling between outer ring and the flange plate has lubriation material.The upper black box of this type of hub-bearing unit as shown in Figure 5, its structure is comparatively complicated, and need use press to press-fit when installing, black box easily destroys the raceway groove between outer ring and the flange in press-fiting process, in addition, because upper black box is thinner, also easily occurs problem on deformation in the assembly process.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes in the above-mentioned background technology, and sealing configuration on a kind of third generation hub-bearing unit spring steel skeleton is provided, and the sealing structure should have characteristics simple in structure, easy for installation.
The technical solution adopted in the utility model is: sealing configuration on the third generation hub-bearing unit spring steel skeleton, be installed between the bearing outer ring and bearing inner ring of hub-bearing unit, be positioned at bearing outer ring near an end at car body center, it is characterized in that: described upper sealing configuration is comprised of a laminar metal cirque skeleton and the rubber seal that is fixed on this metal cirque skeleton, described metal cirque skeleton and bearing outer ring coaxial arrangement, in the draw-in groove on the outer embedded axle bearing outer-ring inwall of metal cirque skeleton and rubber seal, the distance coupling between the annulus width of rubber seal and bearing outer ring and the bearing inner ring.
In the described upper sealing configuration, rubber seal is positioned at the side near the car body center, and the metal cirque skeleton is positioned at ball one side near hub-bearing unit.
Described metal cirque skeleton adopts spring steel to make.
Installation method of the present utility model is: with the space between metal cirque skeleton alignment bearings outer ring and the bearing inner ring, make its distortion with hand metal cirque skeleton afterwards, until in the draw-in groove of metal cirque skeleton embedded axle bearing outer-ring, sealing configuration is fixed on this moment, the outer of rubber seal and interior edge are adjacent to respectively the inwall of bearing outer ring, the outer wall of bearing inner ring, with the space sealing between bearing outer ring and the bearing inner ring.
The beneficial effects of the utility model are: the utility model uses spring steel to make laminar metal cirque skeleton, so that the metal cirque skeleton has good elasticity, can return to the original form rapidly after being under pressure in the installation process, simple in structure, easy for installation, need not to use professional tool can finish installment work, and cost of production is also lower, has preferably market prospects.

Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 2, third generation hub-bearing unit comprises for passing through 4-5 fastened by screw between the flange plate 6(flange plate of fixed car wheel hub and the automotive hub), this flange plate forms integral body (being that flange plate and bearing inner ring are one-body molded) near a side (Fig. 2 left direction) at car body center with bearing inner ring 7.Be arranged with on the described bearing inner ring one with the bearing outer ring 3 of its coaxial arrangement, this bearing outer ring is fixed by screws on the car body of automobile, be provided with two groups of bearing balls 4 in the space between bearing outer ring and the bearing inner ring, the two ends in this space are positioned at respectively a side at close car body center by upper Sealing and the upper Sealing of lower seal sealing 5(, lower seal is positioned at the side near automotive hub), be filled with lubricant oil in the space of sealing to reduce force of rolling friction.
Sealing configuration on the designed third generation hub-bearing unit spring steel skeleton of the utility model is installed between the bearing outer ring and bearing inner ring of hub-bearing unit, is positioned at bearing outer ring near an end at car body center.In press-fiting process, easily destroy the raceway groove between outer ring and the flange and hold yielding problem for fear of upper Sealing, described upper sealing configuration adopts spring steel to make by a laminar metal cirque skeleton 1() and the rubber seal 2 that is fixed on this metal cirque skeleton form, described metal cirque skeleton and bearing outer ring coaxial arrangement, in the draw-in groove 8 on the outer embedded axle bearing outer-ring inwall of metal cirque skeleton and rubber seal, the distance coupling between the annulus width of rubber seal and bearing outer ring and the bearing inner ring.In the described upper sealing configuration, rubber seal is positioned at the side near the car body center, the metal cirque skeleton is positioned at ball one side near hub-bearing unit, the internal diameter of described metal cirque skeleton is greater than the external diameter of bearing inner ring, be to have certain interval between metal cirque skeleton and the bearing inner ring, so that the metal cirque skeleton has certain elasticity.
