Problems solved by technology
The traditional automobile rear axle wheel hub bearing is composed of two sets of tapered roller bearings or angular contact ball bearings. Although the wheel hubs in use are stronger and stronger, there are still relatively complex structures, low assembly accuracy, and troublesome installation. The use effect is not good, the sealing effect is not good, and the maintenance is relatively difficult, etc.

Embodiment Construction
[0015] The new automobile rear axle hub bearing assembly structure includes a rear axle hub 1, a rear axle shaft 9, a bearing A2 and a bearing B3, the rear axle shaft 9 is provided with a rear axle hub 1, and the rear axle hub 1 is provided with bosses 4 at intervals , where the bearing A2 is installed on the rear axle shaft 9 outside the boss 4 on one side, and the bearing B3 is installed on the rear axle shaft 9 outside the boss 4 on the other side. The bearing A2 and the bearing B3 are tapered roller bearings respectively, and the outer sides of the inner rings of the bearing A2 and the bearing B3 are respectively provided with bearing slots. A spacer 5 is arranged between the inner rings of the bearing A2 and the bearing B3. The spacer 5 is a variable diameter body. The two ends of the spacer 5 are respectively provided with spacer slots. The spacer 5 is connected to the inner rings of the bearing A2 and the bearing B3. The connecting ring 6 is engaged with each other thro...

The invention relates to a novel automobile rear axle hub bearing assembly structure and belongs to the technical field of automobile rear axle hub production. The assembly structure comprises a rear axle hub, a rear axle shaft, a bearing A and a bearing B; the rear axle shaft is provided with the rear axle hub; bosses are arranged on the rear axle hub at intervals; the bearing A is installed in the position, on the outer sides of the bosses on one side, of the rear axle shaft; the bearing B is installed in the position, on the outer sides of the bosses on the other side, of the rear axle shaft; a spacer bush is arranged between the bearing A and the bearing B; and a connection ring is connected with the bearing A and the bearing B. The assembly structure is simple and convenient to maintain, the cleanliness of the interior of the hub is improved through a sealing piece A and a sealing piece B, and well lubricating of the bearings is ensured; the inner ring of the bearing A and the inner ring of the bearing B make contact with each other through the spacer bush, the situation that the bearing A and the bearing B are not matched in place is avoided, a normal using clearance is ensured, self regulating of the clearance is achieved, and accordingly the life of the bearings is prolonged; and the balance and safety performance of an automobile are improved.
Description
technical field [0001] The invention relates to a novel automobile rear axle wheel hub bearing assembly structure, which belongs to the technical field of automobile rear axle wheel hub production. Background technique [0002] The role of the hub bearing is mainly as a load-bearing part and to provide precise guidance for the transmission of the hub. It bears both radial load and axial load, and is a very important component. The traditional automobile rear axle wheel hub bearing is composed of two sets of tapered roller bearings or angular contact ball bearings. Although the wheel hubs in use are stronger and stronger, there are still relatively complex structures, low assembly accuracy, and troublesome installation. The use effect is not good, the sealing effect is not good, and the maintenance is relatively difficult. Contents of the invention [0003] The object of the present invention is to provide a new automobile rear axle wheel hub bearing assembly structure wit...
