The space of partial automobile can be taken, compartment passenger's handling capacity of passengers and battery arrangement space is influenced, influences vehicle continual mileage.
The content of the invention
For overcome the deficiencies in the prior art, the goal of the invention of the utility model is to provide a kind of by driving motor, gear
Case and tradition machinery vehicle bridge are integrated into an electric axle assembly, and such a compact structure arrangement can shorten driving-chain and improve effect
Rate, improves compartment passenger capacity and increases the battery capacity in compartment, so as to reduce unit mounted mass energy consumption.
To achieve the above object, the utility model uses following technical solution：A kind of suspension type dual-motor electric car
Axle assembly, including mechanical vehicle bridge, it is characterised in that：Further include the first driving motor, the second driving motor and gear-box；Described
One driving motor, second driving motor couple respectively with two torque input ends of gear-box, gear-box moment of torsion it is defeated with hold and machine
Tool vehicle bridge couples, and forms electric axle assembly；Mechanical vehicle bridge, the first driving motor, the second driving motor and gear-box are using flat
Row structure is arranged.
Gear-box described in the technical solution of the utility model includes the retarder being integrated in gear box casing
And differential assembly.
Retarder described in the technical solution of the utility model be by the first roller gear, double cylindrical gear and
The double reduction retarder that second roller gear is formed.
The gear of retarder described in the technical solution of the utility model is installed on the poor shell of mechanical vehicle bridge, and
The gear of retarder and the two-wheeled end of mechanical vehicle bridge are coaxial.
The first driving motor, the second driving motor described in the technical solution of the utility model are symmetrically distributed in tooth
The both sides of roller box, are connected using flange-interface bolt with gear-box.
The utility model based on existing traditional vehicle bridge power transmission arrangment, by first drive motor, the second driving motor,
Gear-box and mechanical vehicle bridge are integrated into an electric axle assembly, eliminate transmission shaft and active and passive gear, the first driving motor,
The moment of torsion of second driving motor output is by being input to wheel end after gear-box.The utility model structure characteristics of compact layout, shortens transmission
Chain, improves transmission efficiency, improves compartment passenger capacity and increases the battery capacity in compartment, disappears so as to reduce unit charge material energy
Consumption, has the higher steady efficiency of power output, compact-sized weight saving, increase compartment passenger space and battery arrangement space
The characteristics of.
