Is a perspective view of a screw of a drive wheel axle device.

As shown in Figures 2 to 6, the configuration of the drive wheel axle device of the vehicle according to an embodiment of the present invention, the steering knuckle 10 is connected to the steering device and the inside of the steering knuckle 10 described above. The hub bearing 20 press-fitted into the assembly, the snap ring 30 is fitted to the inner circumferential surface of the steering knuckle 10 to prevent separation of the hub bearing 20, and the hub bearing 20 The hub 45 is press-assembled to the inner ring of the hub 45 having two splines formed on the inner circumferential surface thereof, and the spline corresponding to the two-stage spline of the hub 45 described above on the outer circumferential surface of the hub 45. And a sprocket coupled to the drive shaft 55 is inserted through the washer 60 and the nut 70 is fixedly coupled to the wheel shaft, and the wheel disk is fixed to the outer circumferential surface of the hub 45 using the hub bolt 80 90 is made.

A tab 453 is formed on an outer circumferential surface of the hub 45, and has a structure that is coupled to the screw 100.

The screw 100 has a tab 101 for engaging with the tab 453 of the hub 45 is formed on the inner peripheral surface, the operator is easy to rotate on the outer peripheral surface using a tool (not shown) And holes 102a and 102b are formed to facilitate assembly.

After the screw 100 is engaged with the hub 45, the one end of the tab 453 of the hub 45 is caulked toward the holes 102a and 102b to prevent loosening. Caulking is applied.

The first spline 451 and the second spline 452 are formed with different diameters on the inner circumferential surface of the hub 45, and the diameter of the first spline 451 is larger than the diameter of the second spline 452. The stepped jaw of the boundary surface of the first spline 451 and the second spline 452 is formed as a stopper.

On the outer circumferential surface of the drive shaft 55, the third spline 551 and the fourth spline 552 corresponding to the first spline 451 and the second spline 452 of the hub 45 respectively have a diameter. Is formed differently, the diameter of the third spline 551 is formed larger than the diameter of the fourth spline 552, the stepped jaw of the interface between the third spline 551 and the fourth spline 552 It acts as a stopping jaw.

According to the above configuration, the operation of the driving wheel axle device of the vehicle according to the embodiment of the present invention is as follows.

When the rotational power transmitted from the engine when the vehicle is running is transmitted to the hub 45 through the drive shaft 55 coupled to the center of the hub 45, the hub bolt 80 to the hub 45 by using The wheel (not shown) is rotated together with the wheel disk 90 which is fixedly coupled so that the vehicle moves forward.

The steering force transmitted from the steering apparatus to the steering knuckle 10 is fixed to the hub 45 through a hub bearing 20 installed between the steering knuckle 10 and the hub 45 ( 90) with the wheels (not shown) to allow steering to be achieved.

In this case, the snap ring 30 serves to fix the hub bearing 20 so that the hub bearing 20 is not separated, and the screw 100 fastened to the outer circumferential surface of the hub 45 is It serves to adjust the preload of one hub bearing 20.

Meanwhile, the first spline 451 and the second spline 452 formed on the inner circumferential surface of the hub 45, and the third spline 551 and the fourth formed on the outer circumferential surface of the drive shaft 55. In the case where the splines 552 are coupled to each other, the stepped distance between the boundary surface of the first spline 451 and the second spline 452 and the boundary surface of the third spline 551 and the fourth spline 552 As the gap b is formed at the contact portion between the hub 45 and the drive shaft 55, the hub 45 and the hub bearing 20 and the drive shaft 55 do not come into contact with each other, thus the hub 45 and the hub bearing. Since the slip phenomenon of the 20 and the drive shaft 55 is prevented, noise is prevented.
