Abstract
A rear drive axle assembly of a high-end light-duty coach comprises a main reducer, a differential, a half axle and a drive axle shell, and is characterized in that a compressible spacer bush (4) is arranged between inner and outer bearings of the main reducer, the main reducer (7) is cooperatively connected to a differential shell (14) through left and right bearings (9, 17), and gaskets (10) are arranged on left and right bearings (9, 17) at the axial sides cooperating with the differential shell (14). More advanced techniques and processes are employed in the rear drive axle than a common rear drive axle, thereby effectively improving use performance of an entire axle. Moreover, the rear drive axle assembly, especially for a high-end light-duty coach, is better in bearing capacity, comfortableness and safety.
Description
Technical field
The utility model relates to a kind of rear driving axle assembly of high-grade light bus.
Background technology
Drive axle is in the end of Power Train; Its basic function is to increase the torque of being transmitted by transmission shaft or change-speed box, and power is reasonably distributed to the left and right driving wheel, also bears the vertical power, longitudinal force and the transverse force that act between road surface, vehicle frame or the vehicle body in addition; Drive axle generally is made up of main reduction gear, diff, semiaxis and driving axle housing etc.; At present, the client to vehicle comfortable, stable, safety requirements is higher, and existing vehicle bridge can not meet the demands.
The utility model content
The purpose of the utility model is exactly can not satisfy the defective of client to comfortable, stable, the safety requirements of vehicle in order to overcome existing vehicle bridge, and a kind of rear driving axle assembly of high-grade light bus is provided.
The utility model solves the technical scheme that its technical matters adopted:
A kind of rear driving axle assembly of high-grade light bus comprises main reduction gear, diff, and semiaxis, driving axle housing is characterized in that: be provided with compressible spacer between two main pinions of main reduction gear hold.
On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:
