Abstract
The utility model relates to a car wheel hub assembly. The utility model aims to provide the car wheel hub assembly which can save parts and is simple in assembling. The car wheel hub assembly comprises a wheel hub, a conical roller bearing and an oil seal, wherein the conical roller bearing is arranged in a shaft head connection cavity of the wheel hub. The car wheel hub assembly is characterized in that an inner ring of the conical roller bearing extends along the axial direction to form a circle of an extending part; and an oil seal is sleeved on the extending part. Preferably, the length of the extending part of the inner ring of the conical roller bearing is 5-30mm. According to the car wheel hub assembly, an isolation ring structure on the wheel hub assembly is canceled and an isolation ring and an inner bearing are directly designed into one extending part which is lengthened toward the center of a bridge from the inner ring of the bearing, so that the variety of parts is reduced, and the manufacturing and assembling costs are reduced.
Description
Technical field
The utility model relates to the improvement structure on a kind of automotive hub assembly.
Background technique
The general structure of existing automotive hub assembly, as shown in Figure 1, generally comprise wheel hub 1, tapered roller bearing 2, oil sealing 3, spacer ring 4 and wheel bolt etc., tapered roller bearing 2 is arranged in the cavity at wheel hub rear portion, oil sealing 3 is arranged on the bearing, spacer ring 4 is connected with the interior ring of tapered roller bearing, is used for being connected between spindle nose and the tapered roller bearing.The required part of this kind mechanism is more, the assembling more complicated.
The model utility content
At deficiency of the prior art, the utility model aims to provide a kind of saving part, the automotive hub assembly that assembling is simplified.
In order to address the above problem, this kind automotive hub assembly, comprise wheel hub, tapered roller bearing and oil sealing, the spindle nose that tapered roller bearing is arranged on wheel hub connects in the cavity, this automotive hub assembly is characterised in that: the interior ring of described tapered roller bearing extends axially out a circle extending portion along it, and oil-sealing sleeve is located on this extending portion.
Preferably, the interior ring extending portion length of described tapered roller bearing is 5～30mm.
The beneficial effects of the utility model are: the utility model has been cancelled the spacer ring structure on the hub assembly, and spacer ring and inner bearing directly are designed to the extending portion that a bearing inner ring lengthens toward the bridge center, reduces the part kind, reduces manufacturing, assembly cost.
Description of drawings
Fig. 1 is the structural representation of automotive hub assembly of the prior art;
Fig. 2 is the structural representation of automotive hub assembly of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 2, this kind automotive hub assembly comprises wheel hub 1, tapered roller bearing 2 and oil sealing 3, and the spindle nose that tapered roller bearing 2 is arranged on wheel hub 1 rear portion connects in the cavity, and the axle center side is pointed at the wheel hub rear portion here.The interior ring of this tapered roller bearing 2 extends axially out a circle extending portion 21 along it, and this extending portion length is 5～30mm, and oil sealing 3 is set on this extending portion 21, in order to seal an end of tapered roller bearing.
By the spacer ring structure on the cancellation hub assembly, spacer ring and inner bearing directly are designed to the extending portion that a bearing inner ring lengthens toward the bridge center, reduce the part kind, reduction is made, assembly cost.
