Problems solved by technology
[0003] When disassembling the axle hub system, the bearing nut is loosened, and the hub can be separated from the hub. However, when the hub is separated from the hub, the bearing and oil seal will fall off through the end of the hub, resulting in lubrication in the axle hub system. Grease loss. When the bearing and oil seal fall off in a harsh environment, water vapor, dust, sediment and other impurities will enter the axle hub system, contaminate the grease, and cause the axle hub system to wear during use, thus affecting the axle hub system. Long service life, shorten the maintenance-free period of the axle hub system

The application discloses an automobile and an axle hub system thereof. The automobile comprises the axle hub system, wherein the axle hub system comprises a hub, an oil seal, a oil seal seat, bearings, an axle head nut, and an end cover; the axle hub system also comprises check rings and locking rings, wherein a clamping groove is formed in the end part of the hub; and the check rings are clamped in the clamping groove, and the bearings and the oil seal are placed on the inner sides of the check rings. The check rings are clamped in the clamping groove formed in the end part of the hub, in the disassembling process of the axle hub system, the condition that the bearings and the oil seal come off can be avoided, and running off of lubricating grease in the axle hub system can be reduced. Besides, the condition that impurities enter the axle hub system in the disassembling process can also be avoided, and the impurities can be prevented from polluting the lubricating grease, so that the maintenance period of the axle hub system can be prolonged, and the non-maintaining period of the axle hub system can be prolonged to 800 thousands kilometres or three years; and therefore, the maintenance frequency of the axle system is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automobile and its axle hub system. Background technique [0002] The axle hub system of a car generally consists of hubs, oil seals, bearings, spacers, axle nuts and end caps. When the car is running, the axle hub system can rotate with the wheels. The main function of the axle hub system is to transmit the force on the wheel to the axle head through the wheel bearing, and the braking force can be transmitted to the hub through the connection between the brake disc and the brake drum. [0003] When disassembling the axle hub system, the bearing nut is loosened, and the hub can be separated from the hub. However, when the hub is separated from the hub, the bearing and oil seal will fall off through the end of the hub, resulting in lubrication in the axle hub system. Grease loss. When the bearing and oil seal fall off in a harsh environment, water vapor, dust...
