Compared with prior art, the invention has the following advantages that
One, the distributed drive system configuration scheme of the invention that vehicle body is arranged in using bi-motor and retarder, all
It for spring carried mass, and can arrange according to the demand of user, so that vehicle has preferable ride comfort.
Two, double reduction improves the transmission of transmission system using the design of planetary gear set in retarder of the invention
Efficiency, operate it is more stable it is smooth, noise is small in the application.
Three, bi-motor and reducer integrated Integrated design are improved the compactedness of whole system, saved by the present invention
It is longitudinally arranged space, structure is simple, and manufacturing cost is low.
Four, the electric car for equipping the distribution driving axis can make vehicle by the torque distribution control to motor
With more preferably energy consumption and dynamics Controlling performance, when vehicle big corner occurs during running at high speed or low attached road traveling
When steering, since side force of tire reaches limit of adhesion, unstability often occurs for vehicle, can according to distributed drive system
The driving motor for controlling left and right wheels adjusts the drive brake force of left and right wheels, generates additional yaw moment, improves the sideway of vehicle
Movement, improves the control stability of vehicle.
Five, the distributed driving axis of integration of the invention can according to different demands matched design motor and retarder,
To adapt to different vehicle demands, there is stronger versatility.
