The electric vehicle is a dual-drive dual-steering electric vehicle, which is mainly composed of a vehicle body, a driving device, an auxiliary device and a control device. The vehicle body includes a front wheel, a rear wheel, a frame and a steering wheel. The driving device includes a battery, a front wheel motor and a rear wheel motor, and the front wheel motor and the rear wheel motor are connected to the battery by a power connection line. The auxiliary device includes two auxiliary wheels and a support frame. The control device includes a control panel, a steering control device and a control wire. The battery, the front wheel motor and the rear wheel motor are respectively connected to the control panel through the control wire. A control button is arranged on the control panel. The second gear is powered by the front and rear wheels. The steering control device includes bevel gear drive, worm drive, universal joint and various drive shafts. The various drive shafts are connected by bevel gears, worm gears and universal joints, which in turn control the steering of the front and rear wheels.

Dual-drive principle: When you need to use an electric vehicle, press the first-gear button when driving on flat ground, and the rear-wheel drive is used; if it is climbing, turning in situ or when the power is not enough, press the second-gear button to achieve It's dual drive front and rear.

Double steering principle: In the control of direction, change the control method in which the front wheel is used as the steering wheel to drive the rear wheel. When the steering wheel 1 is turned, the steering shaft 2 is driven, and through the universal joint 3, the power can be transmitted to the first connecting shaft 4, and the power on the shaft 4 can be transmitted through the first worm and bevel gear installed on the shaft. Transmission by two lines: the first line is transmitted to the first worm wheel 6 through the first worm 5, and the worm wheel 6 is coaxial with the front fork 7 on which the front wheel 8 is installed, so the front wheel and the steering wheel can be controlled in the same direction through this line Rotation; the direction control of the rear wheel is realized through the second line, that is, the front bevel gear drives the rear bevel gear (4 pairs in total) and three steering shafts (the first steering transmission shaft 10, the second steering transmission shaft 11, the third steering transmission shaft 11, the third steering transmission shaft The steering transmission shaft 14) transmits the power to the second connecting shaft 21, and then drives the movement of the second worm wheel 18 through the second worm 20 installed on the second connecting shaft 21, thereby driving the rotation of the rear fork 16, thereby driving the rear wheel 15 reverse rotation. In the control of the direction of the front and rear wheels, the steering wheel can be turned and the angle of the front and rear wheels can be adjusted at the same time, making the steering control more agile and realizing steering in a narrow space. At the same time, the auxiliary wheels 12 and 13 on the left and right sides can ensure stronger safety performance.

Both the front and rear wheels of the electric vehicle in this embodiment include motors. When driving under normal road conditions, only the rear wheel motors can be driven to achieve the required speed and power. When the slope is large or the road conditions are poor, the front wheel and rear wheel motors are turned on at the same time, and the front and rear wheels both become driving wheels. Steering is much easier than a single-drive electric car. During the driving process, the two motors not only assist each other, but also backup each other. Even if one motor fails, it can continue to ride, so it can better meet people's new needs for electric vehicles. At the same time, a worm mechanism is added to the original electric vehicle steering control device, which is convenient to adjust the angle of the front and rear wheels at the same time, making the steering control more convenient and reliable. At the same time, two auxiliary wheels are arranged side by side on both sides of the electric vehicle, which can ensure that there are at least three support points between the front and rear wheels, the two auxiliary wheels and the ground. Drive safely. In addition, the four wheels of the electric vehicle of the present invention are arranged in a diamond shape as shown in the schematic diagram. When turning, the front wheels and rear wheels rotate in opposite directions. When turning, all four wheels follow the tangent of the turning circle, so the loss during turning is less than that of ordinary vehicles, the steering is more sensitive, and the turning radius is close to zero, which can be turned on the spot.
