The weld strength of axle housing.
Preferably, the spindle nose for first fixing both ends, then processes the undergauge structure of the axle housing, then by the wheel hub
Internal bearing sleeve can effectively promote the concentricity of both ends spindle nose in the undergauge structure.
Preferably, the axle shell assembly further comprises: locking nut and locking plate.The inner ring of the wheel hub outer bearing
It is positioned by locking nut；The boss of the locking plate and the groove of spindle nose are clamped, for preventing locking nut from falling off.
Preferably, the axle shell assembly further comprises: oil sealing seat ring, O-ring, hub oil seal and axle-shaft oil seal etc.
Sealing structure.Wherein the end face of the hub inner bearing is bonded with the end face of oil sealing seat ring, the inner hole of the oil sealing seat ring and institute
Undergauge structure welding is stated, and is sealed by being sheathed on O-ring in the undergauge structure；Outer diameter and the wheel hub oil of the oil sealing seat ring
The seal lip of envelope cooperates, and the hub oil seal is pressed into and fits in the stepped hole of wheel hub；The sealing lip of spindle nose oil sealing with it is described
Spindle nose other end interference fit, passes through above-mentioned sealing structure；To effectively avoid extraneous dust, impurity etc. from entering the bearing
It is internal.
Preferably, the inner face of the oil sealing seat ring uses circular groove structure, for mitigating pts wt.
Preferably, the end face of the hub oil seal rectangle tooth slot structure uniformly distributed using annular, cooperates with speed probe,
For acquiring tach signal.
Preferably, axle shell assembly further comprises: braking flange and brake assembly, the inner hole of the braking flange
It welds with the outer diameter of axle housing, and is connect by bolt with the brake assembly.
The beneficial effects of the present invention are: 1. are cooperated by the undergauge structure of press-in type spindle nose and axle housing, axis is simplified
Head mechanism, reduces processing cost；2. using the welding manner of annular fillet welding, the connection that can promote spindle nose and axle housing is strong
Degree；3. reprocessing the undergauge structure of the axle housing using the spindle nose for first fixing both ends, can effectively promoting both ends spindle nose
Concentricity；4. hub inner bearing is sheathed in the undergauge structure of axle housing, hub inner bearing carrying can be effectively promoted
Ability and reliable transmission.
