| 摘要 |
The present invention relates to a driving wheel axle device of a vehicle capable of removing a slip phenomenon caused by the abrasion of an outer surface of a hub by pressurizing a hub bearing to a driving shaft having similar hardness to the hub bearing's, not a hub having hardness relatively lower than the hub bearing's. The device includes a steering knuckle connected to a steering device, a hub bearing pressurized into the steering knuckle and having an inner surface combined with the driving shaft, a snap ring preventing the separation of the hub bearing by being inserted into the inner surface of the knuckle, a driving shaft pressurized into the inner surface of the hub bearing, a hub placed behind the hub bearing, combined with an outer surface of the driving shaft, and fixed by using a lock nut, and a wheel disk fixed to a flange surface of the hub by using a hub bolt and a bolt. |
