There is a problem in that the noise generated by the slip of the two objects in the contact surface (a) of the increase the fatigue of the driver.

An object of the present invention is to solve the conventional problems as described above, to provide a driving wheel axle device for a vehicle that can prevent the generation of noise due to the slip so that the contact portion of the drive shaft and the hub bearing is firmly coupled to each other. There is.

As a means for achieving the above object, the configuration of the present invention includes a steering knuckle connected to a steering device, a hub bearing press-fitted to the inside of the steering knuckle and coupled to a drive shaft, and fitted to the inner circumferential surface of the steering knuckle. A snap ring coupled to prevent separation of the hub bearing, a hub press-assembled into the inner ring of the hub bearing, a drive shaft splined to the inner diameter of the hub and coupled to the hub bearing, and the hub of the hub It is preferable to include a wheel disk fixed to the outer circumferential surface by using a hub bolt.

The configuration of the present invention is preferably such that a gear coupling portion is formed at a portion of the hub bearing facing the drive shaft.

The configuration of the present invention is preferably such that a gear coupling portion is formed at a portion of the drive shaft facing the hub bearing.

The configuration of the present invention is preferably such that the gear coupling portion is made of a groove having a rectangular shape.

The configuration of the present invention is preferably such that the tooth coupling portion is made of a trapezoidal groove.

In the configuration of the present invention, it is preferable that the drive shaft is inserted into the hub and fixedly coupled using a washer and a nut.

The present invention is to ensure that the contact portion of the drive shaft and the hub bearing is firmly coupled to each other to prevent the generation of noise due to slips to provide a comfortable driving environment and to reduce the fatigue of the driver.
