It is connect with 10 one end of the first steering drive axle, 10 other end of the first steering drive axle passes through gear and the second steering drive axle 11 1
End connection, 11 other end of the second steering drive axle are connect by gear with 14 one end of third steering drive axle, and third turns to transmission
14 other end of axis is connect by gear with the second connecting shaft 21, and the second connecting shaft 21 is connect with the second worm screw 20, the second worm screw 20
It is connect by the second worm gear 18 with transmission shaft 19, transmission shaft 19 is connect with rear fork.The wheel further includes right redundant wheel and inside left
Help wheel, the right redundant wheel and left redundant wheel are arranged side by side respectively on vehicle frame, and the right redundant wheel and left redundant wheel distinguish position
Between front vehicle wheel and rear wheel.The wheel is equipped with shock absorber 9.The gear includes front cone gear and rear circular cone tooth
Wheel carries out the connection between axis and axis, such as the first connecting shaft 4 by the mating connection of front cone gear and rear conical gear
It is connected by front cone gear and the first steering drive axle of rear conical gear 10.
Electric vehicle is double drive double steering electric vehicle, mainly by portions such as car body, driving device, auxiliary device and control devices
It is grouped as.The car body includes front-wheel, rear-wheel, vehicle frame and steering wheel.Driving device includes battery, preceding turbin generator and rear-wheel electricity
Machine, preceding turbin generator are connect by electric power connection line with battery with rear-wheel motor.Auxiliary device includes two auxiliary wheels and support frame.Control
Device processed includes control panel, steering control device and control line, and the battery, preceding turbin generator and rear-wheel motor pass through respectively
Control line is connect with control panel, is equipped with control button on the control panel, and one grade is that rear-wheel is powered, and two grades are that front and back two-wheeled is logical
Electricity.Steering control device includes Bevel Gear Drive, worm-drive, universal coupling and each transmission shaft etc..Pass through circular cone tooth
Wheel, worm and gear and universal coupling connect each transmission shaft, and then can control the steering of front vehicle wheel and rear wheel.
Double drive principle: when needing using electric vehicle, next grade of button is pressed when driving on level land, is driven using rear-wheel
It is dynamic；When if it is climbing, pivot stud or inadequate power, then two grades of buttons are pressed, is accomplished that front and back two-wheeled double drive.
Double steering principle: in the control in direction, wheel is used as deflecting roller before changing, and drives the control mode of rear-wheel.When
Steering wheel rotation 1 then drives steering shaft 2, by universal coupling 3, the first connecting shaft 4 can be imparted power to, by axis
The first worm screw installed and bevel gear, can transmit the power on axis 4 by two lines road: first route is by the first snail
Bar 5 is transmitted to the first worm gear 6, and worm gear 6 is coaxial with the installation front fork 7 of front-wheel 8, so can control front-wheel and direction by the route
Disk rotates in same direction；The direction controlling of rear-wheel is realized by Article 2 route, i.e., bevel gear (totally 4 after being driven by inner cone gear
It is right) power is transmitted to by Ji Sangen steering shaft (the first steering drive axle 10, the second steering drive axle 11, third steering drive axle 14)
Second connecting shaft 21, then the second worm screw 20 by being installed in the second connecting shaft 21 drive the movement of the second worm gear 18, thus
The rotation of rear fork 16 is driven, and then drives rotating backward for rear-wheel 15.In the control in front and back two-wheeled direction, it may be implemented to rotate
The corner size that front and back wheel is adjusted while steering wheel, keeps course changing control quicker, realizes and turns in small space.Meanwhile it is left
The auxiliary wheel 12 and auxiliary wheel 13 on right both sides can ensure that security performance is stronger.
Two-wheeled contains motor before and after the electric vehicle of present embodiment, in normal road condition downward driving, can only drive rear-wheel electricity
Machine can reach required speed and power.And when the gradient climbed is larger or road conditions are poor, then open simultaneously front-wheel and
Rear-wheel motor, forward and backward wheel become driving wheel, the dynamic characteristics of electric vehicle be improved significantly, either uphill starting, more
Wild or steering, all the electric vehicle than singly driving is much free and relaxed.In the process of moving, two motors not only mutually assist, and
And be mutually backups, even if a motor breaks down, can continue to ride, therefore can preferably meet people to electric vehicle
New demand.Meanwhile increasing worm mechanism on original electric motor car steering control device, corner that is convenient while adjusting front and back wheel
Size keeps course changing control more convenient reliable.Meanwhile two auxiliary wheels are arranged side by side on electric vehicle both sides, it is ensured that front and back two
At least there are three supporting points between wheel, two auxiliary wheels and ground, the anti-side for improving vehicle, which turns over performance, keeps intact stability more preferable,
To ensure vehicle driving safety.In addition, 4 wheels of electric vehicle of the invention are diamond shape arrangements such as schematic diagram.When steering front-wheel with
The rotation of rear-wheel opposite direction, 4 wheels walk the tangent line of turning circle when steering, so loss is less than general vehicle when turning to, turn
To sensitiveer, turning radius is close to zero, it can pivot stud.
