The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-4, including wheel hub flange 1 and wheel hub body 2, the flange face of wheel hub body 2 is excavated and is equipped with a plurality of screw 3 that is the circumference and distributes, a plurality of one number through-hole 4 has been seted up for a plurality of screw 3 on the wheel hub flange 1, a plurality of one number through-hole 4 is the circumference and distributes, it has stud 5 to every equal threaded connection between a number through-hole 4 and a screw 3, when assembling, assemble 10 stud 5 to corresponding every between a number through-hole 4 and a screw 3, brake disc 7 assembles in the outside of wheel hub body 2, wheel hub flange 1 is connected with the flange end dismantlement of brake disc 7, when dismantling brake disc 7, only need dismantle brake disc 7 alone, need not to dismantle the wheel hub assembly.

Wherein, 7 accessible screws 8 of brake disc are connected with

wheel hub flange

1, and 10 No. two screws 8 that are the circumference form and distribute are seted up in the flange end of

brake disc

7, and 10 No. two through-holes 9 have been seted up to 10 No. two screws 8 on the wheel hub flange 1 relatively, and 10 bolt 10 screw thread assembly are every to between No. two screws 8 and No. two through-holes 9, and the tip of bolt 10 all is provided with the integral type gasket, saves assemble duration.

Wherein, 16 millimeters No. two screw 8 and No. one screw 3 more adapt to corresponding connecting piece assembly, and 17 millimeters No. two through-holes 9 and No. one through-hole 4 match with corresponding screw.

Wherein, stud 5 all runs through corresponding every No. 3 screw holes and No. 4 through holes of a pair, and extends to No. 4 outside through holes, and stud 5 is located the equal threaded connection of screw on the outside screw thread of No. 4 through holes and has flange nut 6. The connection is more stable.

The working principle is as follows: firstly, 10 studs 5 are assembled into 10 first screw holes 3 with the diameter of 16 mm on a

hub body

2, 10 first through holes 4 with the diameter of 17 mm on a hub flange 1 are aligned with the exposed part of each stud 5, the hub flange 1 is pushed to the flange surface of the hub body 2 until the studs are completely attached, each stud 5 passes through the thread of the exposed part of each first through hole 4 to be screwed and matched with a corresponding flange nut 6, and the flange nut 6 is completely attached to the small boss of each first through hole 4 on the hub flange 1 and tightened according to a specified torque;

then aligning 10 second screw holes 8 on the flange end of a brake disc 7 of the commercial vehicle with 10 second through holes 9 on a hub flange 1 one by one, and screwing 10 bolts 10 with integrated gaskets through the corresponding second through holes 9 and the second screw holes 8 until 10 bolts 10 with integrated gaskets are tightened by specified tightening torque, so that the split hub can be fixed together;

under the prerequisite of original wheel hub body 2 functions was compromise in the realization, wheel hub flange 1 was dismantled with stud 5 to the accessible dismantlement flange nut 6, the brake disc 7 of assembling on wheel hub flange 1 is dismantled to accessible dismantlement bolt 10 simultaneously, so not only can not influence the sealing performance of 2 oil sealings of wheel hub body, the time of changing brake disc 7 that has significantly reduced simultaneously, under the original technical condition, because wheel hub is holistic, dismantle brake disc 7 and can only pull down the wheel hub assembly, and through applying new technical scheme, can make the more convenient dismantlement brake disc 7 of user, prolong the life-span of wheel hub oil blanket simultaneously.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
