For overcome the deficiencies in the prior art, motor, two grades of speed changes will be driven the purpose of this utility model is to provide a kind of
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 electric axle assembly, including machine
Tool vehicle bridge, it is characterised in that：Further include driving motor and two grades of gearboxes；The driving motor and two grades of gearbox torques input
End connection, mechanical vehicle bridge couple with two grades of gearbox torque output terminals, form electric axle assembly；Mechanical vehicle bridge, driving motor
Arranged with two grades of gearboxes using parallel construction.
Driving motor described in the technical solution of the utility model only includes the first driving motor；First driving
Motor couples with the torque output of two grades of gearbox sides.
Driving motor described in the technical solution of the utility model includes the first driving motor and the second driving electricity
Machine；The torque output of the first driving motor and the second driving motor respectively with two grades of gearbox both sides couples.
The differential mechanism integrated is further included in two grades of gearboxes described in the technical solution of the utility model.
The driving-chain of assembly described in the technical solution of the utility model is horizontally disposed, drives the moment of torsion of motor to lead to
Cross two grades of gearboxes and be input to two side wheel ends.
The utility model is based on existing traditional vehicle bridge power transmission arrangment, by driving motor, two grades of gearboxes and tradition
Mechanical vehicle bridge is integrated into an electric axle assembly, eliminates transmission shaft and active and passive gear, and the moment of torsion of driving motor output leads to
Wheel end is input to after crossing two grades of gearboxes, driving motor, two grades of gearboxes are parallel with wheel end semiaxis.The utility model has broken away from biography
Unite mechanically operated design constraint, eliminate the components such as transmission shaft, differential mechanism, be simplified transmission system, structure arrangement is tight
Gather, be conducive to automobile and realize lightweight target, vehicle production cost is expected to reduce.The utility model shortens driving-chain, matches phase
The reducing gear answered reduces rotating speed to obtain larger torque, and transmission efficiency is improved.The utility model occupied space is few, makes
Arrangement design is very flexible, saves more spaces.The utility model improves compartment passenger capacity and increases the battery in compartment
Capacity, so as to reduce unit mounted mass energy consumption, have the higher steady efficiency of power output, compact-sized weight saving,
The characteristics of increasing compartment passenger space and battery arrangement space.
