It unloads and is fixedly connected, the outer ring flange of the hub bearing is detachably fixed with the axle housing flange and connect.
A kind of semi-floating drive axle hub end component of the utility model may also is that
The hub bearing is double-row angular contact bal bearing.
Adapter sleeve is arranged on the semiaxis, the hub bearing is connected by the adapter sleeve and semiaxis interference fit
It connects.
Oil sealing, the adapter sleeve and the axle housing flange are equipped between the adapter sleeve and the axle housing flange described in
Oil sealing sealing is connected on the semiaxis.
A kind of semi-floating drive axle hub end component of the utility model, including brake, brake drum, semiaxis, hub spindle
Hold with axle housing flange, for the brake between the hub bearing and the axle housing flange, the brake is detachably solid
Due on the axle housing flange, the brake drum is removably fixed on the semiaxis, the brake and the brake drum phase
To rotation, the hub bearing interference fit is sheathed on the semiaxis, and the inner ring of the hub bearing and the semiaxis are removable
It unloads and is fixedly connected, the outer ring flange of the hub bearing is detachably fixed with the axle housing flange and connect.In this way, the utility model
Semi-floating drive axle hub end component be made of brake, brake drum, semiaxis, hub bearing and axle housing flange, hub bearing
It is transition fit with axle housing flange shaft bearing bore, semiaxis does not need to be pressed when being assembled to axle housing flange, hub bearing raceway and roller
It is not subjected to press fitting impact force, hub bearing is solved and assembles damage problem, the outer ring flange of hub bearing passes through bolt and axle housing
Flange fastening is reliable, and hub bearing and axle housing flange shaft bearing bore are transition fit, while can be to avoid because of axle housing flange shaft bearing bore
Cylindricity control is insufficient and magnitude of interference is excessive causes hub bearing raceway to deform, and influences hub bearing working gap and performance.And
And moved outside the hub bearing of the application, reduce hub bearing center and tire centerline away from improvement hub bearing stress promotes wheel hub
Bearing life.A kind of semi-floating drive axle hub end component of the utility model, integrated level height, bearing capacity and sealing function
Property it is high, improve bearing life, and then promote user satisfaction.

Specific embodiment
Fig. 1 with reference to the accompanying drawing makees a kind of semi-floating drive axle hub end component of the utility model further detailed
Explanation.
A kind of semi-floating drive axle hub end component of the utility model, referring to FIG. 1, include brake 2, brake drum 1,
Semiaxis 4, hub bearing 6 and axle housing flange 7, the brake 2 is between the hub bearing 6 and the axle housing flange 7, institute
It states brake 2 to be removably fixed on the axle housing flange 7, the brake drum 1 is removably fixed on the semiaxis 4, described
Brake 2 and 1 relative rotation of brake drum, the interference fit of hub bearing 6 are sheathed on the semiaxis 4, the wheel hub
The inner ring of bearing 6 is detachably fixed with the semiaxis 4 and connect, and the outer ring flange of the hub bearing 6 and the axle housing flange 7 can
Disassembly is fixedly connected.In this way, the semi-floating drive axle hub end component of the utility model by brake 2, brake drum 1, semiaxis 4,
