Abstract
Entitled a kind of suspension type single motor electric axle assembly of the invention.Belong to field of automobile.It mainly solves the problems, such as that existing pure electric automobile is longer there are transmission chain due to using the power unit structure of traditional combustion engine automobile and occupies partial automobile space.Being mainly characterized by comprising: for it includes mechanical vehicle bridge, driving motor and gear-box;The driving motor couples with gear-box torque input end, and gear-box torque is defeated to be connect with end with mechanical car bridging, composition electric axle assembly;Mechanical vehicle bridge, driving motor and gear-box are arranged using parallel construction.The present invention has the characteristics that the higher steady efficiency of power output, compact-sized weight saving, increases compartment passenger space and battery arrangement space, improves product applicability and competitiveness, is mainly used for the electric axle power assembly of pure electric vehicle.
Description
Technical field
The invention belongs to field of automobile, and in particular to a kind of electric axle power for pure electric vehicle is total
At.
Background technique
Currently, most pure electric automobiles are all made of the power unit structure of traditional combustion engine automobile, i.e. motor, transmission
Axis, retarder/differential assembly.Since transmission chain is longer, cause transmission efficiency loss larger, and each components volume is larger,
The space that partial automobile can be occupied influences compartment passenger's passenger capacity and battery arrangement space, influences vehicle continual mileage.
Summary of the invention
In order to overcome the deficiencies of the prior art, goal of the invention of the invention be to provide it is a kind of by driving motor, gear-box and
Tradition machinery vehicle bridge is integrated into an electric axle assembly, and such compact structure arrangement can shorten transmission chain and improve efficiency,
It improves compartment passenger capacity and increases the battery capacity in compartment, to reduce unit mounted mass energy consumption.
To achieve the above object, the present invention uses following technical solution: a kind of suspension type single motor electric axle is total
At, including mechanical vehicle bridge, it is characterised in that: it further include driving motor and gear-box, it is characterised in that: the driving motor and tooth
The connection of roller box torque input end, gear-box torque is defeated to be connect with end with mechanical car bridging, composition electric axle assembly;Mechanical vehicle bridge,
Driving motor and gear-box are arranged using parallel construction.
Gear-box described in technical solution of the invention includes the retarder being integrated in gear box casing and difference
Fast device assembly.
Retarder described in technical solution of the invention is by the first roller gear, double cylindrical gear and second
The double reduction retarder that roller gear is constituted.
Gear-box described in technical solution of the invention reserves motor interface position.
The gear of retarder described in technical solution of the invention is mounted on the poor shell of mechanical vehicle bridge, and is slowed down
The gear of device and the two-wheeled end of mechanical vehicle bridge are coaxial.
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.Structure of the invention characteristics of compact layout shortens transmission chain, improves transmission efficiency, improves compartment passenger capacity and increases vehicle
The battery capacity in compartment has the steady efficiency of power output higher, compact-sized heavy to reduce unit mounted mass energy consumption
Amount mitigates, increases the characteristics of compartment passenger space and battery arrangement space.

Specific embodiment
As shown in Figure 1 and Figure 2.A kind of suspension type single motor electric axle assembly of the present invention includes mechanical vehicle bridge 3,1 and of driving motor
Gear-box 2.Wherein, mechanical vehicle bridge 3 is using the tradition machinery vehicle bridge in traditional pure electric vehicle driving unit.Driving motor 1 uses
Motor in traditional pure electric vehicle driving unit.Gear-box 2 includes that the retarder being integrated in gear box casing 8 and differential mechanism are total
At 7.Retarder is the double reduction retarder being made of the first roller gear 4, double cylindrical gear 5 and the second roller gear 6,
Two side wheel ends of mechanical vehicle bridge 3 are input to after the two gear-stage velocity ratios amplification that the torque of driving motor 1 passes through gear-box 2.Driving motor 1
It is bolted with the torque input end of 2 side of gear-box using flange-interface.2 torque of gear-box is defeated and holds and mechanical vehicle bridge 3
It connects, second roller gear 6 of retarder is mounted on the poor shell of mechanical vehicle bridge 3 in gear-box 2, and the second roller gear 6 and machine
The two-wheeled end of tool vehicle bridge 3 is coaxial.The present invention adopts a split structure design, and mechanical vehicle bridge 3, driving motor 1 and gear-box 2 use
Parallel construction arrangement, constitutes electric axle assembly.The other side of gear-box 2 can also reserve motor interface position, can be according to client
Increase in demand motor (bi-motor is optional).
The present invention incorporates motor in traditional pure electric vehicle driving unit, retarder, transmission shaft and tradition machinery vehicle bridge
Function, and structurally and functionally instead of them.By driving motor, gear-box and tradition machinery vehicle bridge be integrated into one it is electronic
Axle assembly eliminates transmission shaft and active and passive gear, and the torque of motor output is by being input to wheel end, driving electricity after gear-box
Machine 1, gear-box 2 are parallel with the mechanical wheel end semiaxis of vehicle bridge 3.
