Description
Technical field
The invention belongs to field of automobile, specifically a kind of electric axle power for pure electric vehicle is total
At.
Background technique
Currently, the power unit structure for being all made of traditional combustion engine automobile of most pure electric automobiles, i.e. motor, biography
Moving axis, retarder/differential assembly.Cause transmission efficiency loss larger since transmission chain is longer, 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, the purpose of the present invention is to provide it is a kind of by driving motor, two grades of gearboxes 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 electric axle assembly, including mechanical car
Bridge, it is characterised in that: further include driving motor and two grades of gearboxes；The driving motor and two grades of gearbox torque input terminals join
It connects, mechanical vehicle bridge couples with two grades of gearbox torque output ends, constitutes electric axle assembly；Mechanical vehicle bridge, driving motor and two
Shelves gearbox is arranged using parallel construction.
Driving motor described in technical solution of the invention only includes the first driving motor；First driving motor
Couple with the torque output of two grades of gearbox sides.
Driving motor described in technical solution of the invention includes the first driving motor and the second driving motor；It should
First driving motor and the second driving motor couple with the torque output of two grades of gearbox two sides respectively.
It further include the differential mechanism integrated in two grades of gearboxes described in technical solution of the invention.
The transmission chain of assembly described in technical solution of the invention is horizontally disposed, and the torque of driving motor passes through two
Shelves gearbox is input to two side wheel ends.
The present invention is based on existing traditional vehicle bridge power transmission arrangments, by driving motor, two grades of gearboxes and tradition machinery
Vehicle bridge is integrated into an electric axle assembly, eliminates transmission shaft and active and passive gear, and the torque of driving motor output passes through two
Wheel end is input to after shelves gearbox, driving motor, two grades of gearboxes are parallel with wheel end semiaxis.The present invention gets rid of tradition machinery biography
Dynamic design constraint eliminates the components such as transmission shaft, differential mechanism, is simplified transmission system, and structure characteristics of compact layout is conducive to
Automobile realizes lightweight target, and vehicle production cost is expected to reduce.The present invention shortens transmission chain, matches corresponding deceleration mechanism drop
To obtain biggish torque, transmission efficiency is improved for the slow-speed of revolution.Occupied space of the present invention is few, keeps arrangement design very clever
It is living, save more spaces.The present invention improves compartment passenger capacity and increases the battery capacity in compartment, to reduce unit mounted mass
Energy consumption, higher, compact-sized weight saving, increase compartment passenger space and battery cloth with the steady efficiency of power output
The characteristics of emptying.
