Description
Technical field：
The present invention relates to technical fields such as automotive axle, gear reduction units, specifically one kind can realize back axle lifting and drive
Dynamic double drive axle.
Background technology：
Automotive axle carries vehicle and carries, walks, braking, increasing the effect of torsion, transmitting torque and reasonable distribution to left and right wheelses.
Automobile needs vehicle bridge to provide carrying, high pulling torque greatly in full load, and being carried with the dispersion for realizing vehicle is reduced the destruction of road pavement, put down
Steady starting, the function of normal operation, now need all drive axles of vehicle to both participate in carrying and drive；When automobile no-load return trip or
When contained goods is light parabolic product, vehicle presses the carrying of the drive axle of maximum mounted mass design and driving force by great mistake
It is surplus, and because the drive axle quantity for participating in is more, cause that tire frictional resistance is big, vehicle transmission efficiency is low, oil consumption is high.In order to carry
Transmission efficiency of the vehicle high under unloaded or light condition, cut operating costs, more rational way is to carry jackshaft or back axle
Rise, realize double drive bridges to single conversion for driving bridge.
What current vehicle can realize back axle enhanced feature is carrying bogie, does not have driving function；It is architectural limitation, it is existing
