Input terminal connection, gear-box torque output connect with mechanical car's bridging, constitute electric axle assembly；Driving motor, gear-box with
Mechanical vehicle bridge is arranged using T-type.
The torque input end and torque output of gear-box described in technical solution of the invention are located at tooth
On the side and end face of roller box, the torque output of gear-box couples with the middle part of mechanical vehicle bridge, T-shaped arrangement；Driving motor
Axis use hollow design, have the perforation of central semiaxis wherein.
Gear-box described in technical solution of the invention includes the retarder and wheel being integrated in gear box casing
Between differential mechanism.
Retarder described in technical solution of the invention is by first stage decelerator, center differential and double reduction
The double reduction retarder that device is constituted.
Reserve torque in the opposite another side of the torque input end of gear-box described in technical solution of the invention
Input end interface.
Gear-box described in technical solution of the invention and driving motor are bolted using flange-interface.
The present invention is based on existing traditional vehicle bridge power transmission arrangments, and driving motor, gear-box and mechanical vehicle bridge are integrated
For an electric axle assembly, transmission shaft and active and passive gear are eliminated, the torque of driving motor output passes through defeated after gear-box
Enter to wheel end.Gear-box differential mechanism of the present invention has differential function between central differential and wheel, and the vehicle of client can be made according to need
It asks and switches between 4 wheel driven and two drive modes.Driving motor of the present invention is defeated by torque by two central semiaxis of perforation motor shaft
Enter to front-rear axle, realizes the 4 wheel driven traveling of vehicle, center differential can also be locked according to customer demand, realize two drives of vehicle
Traveling.Axle assembly of the present invention can reduce power according to the instruction of entire car controller, the distribution all around of free switching torque
Loss.Structure of the invention characteristics of compact layout shortens transmission chain, improves transmission efficiency, improves compartment passenger capacity and increases compartment
Battery capacity, to reduce unit mounted mass energy consumption, with the steady efficiency of power output, higher, compact-sized weight subtracts
Gently, the characteristics of increasing compartment passenger space and battery arrangement space and realizing the 4 wheel driven or two drive travelings of vehicle.
