New-energy automobile etc..Either electric bicycle either new-energy automobile, production technology is complex, and to production
Qualification requirement is stringent.But it is in well as mechanical intelligent requires the continuous improvement required equipment controllability, electric power steering apparatus
Spray formula develops, and the utility model can provide a kind of simple controllable Design of Electric Vehicles idea and method.
Utility model content
Purpose of the utility model is to solve the above problems, propose a kind of four-wheel driven electric vehicle, the four-wheel driven electric vehicle
Have the characteristics that design science, reasonable for structure, easy to operate, controlling is reliable.
The purpose of this utility model is achieved through the following technical solutions：Four-wheel driven electric vehicle, it is characterised in that：If
There are the vehicle frame of "door" type, the vehicle frame that front is provided with driver's cabin, the vehicle frame is equipped with two steering front wheels, the vehicle in front
Frame rear portion be equipped with two rear drive sprockets, two steering front wheel, two rear drive sprockets respectively by transmission shaft, universal coupling with
It drives direct current generator power to transmit, is also respectively provided with big deflecting roller on two steering front wheel, the deflecting roller passes through first
Band shift transmission is turned to small deflecting roller and is connected, and the small deflecting roller is turned to by the second band shift transmission and steering motor to be connected
It connects；The vehicle frame of the "door" type is equipped with a recessed space in intermediate lower part, ensures that vehicle has good percent of pass.
The driving direct current generator, steering motor are all made of the power supply of plumbic acid lithium iron battery；The driving direct current generator has
Function of electric braking, it can be achieved that braking of vehicle under the conditions of low speed is walked；The steering motor also uses motor to drive, and sprocket wheel passes
It is dynamic, realize the steering of vehicle.
The driving direct current generator changes the steering of motor, realizes the advance and retrogressing of vehicle by changing current polarity；
By cutting off electric current, the braking to motor is realized in the electromagnetism brake holding of motor tail portion, to control vehicle braking.
The utility model is rotated by using four DC servo motors, and band motor car wheel rotates, and realizes the movement of vehicle；It is logical
Change current polarity is crossed, the steering of motor is changed, realizes the advance and retrogressing of vehicle；By cutting off electric current, the electricity of motor tail portion
The braking to motor is realized in magnetic brake holding, to control vehicle braking；The steering of vehicle drives a smaller chain by direct current generator
Wheel is installed a larger sprocket wheel in wheel hub, is connected using chain, by controlling motor steering, drives minor sprocket, realizes wheel
The rotation of hub, to realize the steering of vehicle.
