[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 5 The utility model provides the following technical solutions: an integrated automobile wheel hub bearing, comprising a base 1 and a bearing column 2, the top of the base 1 is provided with the bearing column 2, the surface of the bearing column 2 is provided with an anti-deviating mechanism, the bearing column 2 comprises a rubber groove 3, a rubber ring 4, a slot 5, a spring groove 6, a spring 7, an insert rod 8, a push block 9 and a connector 10;

[0026] The rubber groove 3 is opened on the surface of the bearing column 2, the rubber ring 4 is engaged in the inside of the rubber groove 3, the slot 5 is opened on one side of the rubber ring 4, the spring groove 6 is opened on both sides of the bearing column 2, the spring 7 is arranged in the inside of the spring groove 6, the plug rod 8 is inserted in the inside of the spring 7, the push block 9 is connected to the surface of the plug rod 8, the connector 10 is arranged at the upper end of the rubber ring 4, and an anti-loss mechanism is arranged inside the base 1.

[0027] Preferably, the size of the rubber ring 4 matches the size of the rubber groove 3 , and the push block 9 forms an elastic structure through the spring groove 6 and the spring 7 . Preferably, the position of the front end of the insertion rod 8 matches the position of the slot 5 .

[0028] During specific use, the spring 7 can push the push block 9 through its own elasticity to drive the front end of the insertion rod 8 to be inserted into the slot 5 for fixation, thereby achieving the fixation of the rubber ring 4.

[0029] Preferably: the anti-loss mechanism includes a limit groove 11, a threaded rod 12 and a limit block 13, the limit groove 11 is opened inside the base 1, the threaded rod 12 is inserted into the limit groove 11, the limit block 13 is connected to the surface of the threaded rod 12, and the limit groove 11 is opened in six groups in a ring shape inside the base 1.
