Embodiment Construction

[0040] The large-wheeled cart with mother and child structure wheels includes a cuboid car body 1, and also includes an axle 2 that runs through and is fixed on the car body 1 along the length direction. Two large-diameter wheels located at both ends of the axle 2 are respectively installed on the Two small-diameter support wheels 3 at the front and rear of the car body 1, a main controller 11, and a storage battery 12;

[0041] The height of the car body 1 is smaller than the diameter of the large-diameter wheel, and the center of gravity of the car body 1 is located below the axle 2;

[0042] The large-diameter wheel includes a large-diameter rim 4 made of a material with good electrical conductivity and is easy to form a strong eddy current for installing tires, and a first bearing 5 and a second bearing 6 fixed side by side on the axle 2;

[0043] The large-diameter rim 4 is a ring shell with a U-shaped longitudinal section. The outer ring surfaces of the bearing outer rin...

Abstract

The invention relates to the field of electric automobiles powered by storage batteries and particularly relates to a big wheeled vehicle with son-mother structure wheels. The big wheeled vehicle comprises a cubic vehicle body and further comprises an axle, two large-diameter wheels, two small-diameter supporting wheels, a main controller and storage batteries, wherein the axle penetrates along the length direction and is fixedly arranged on the vehicle body; the two large-diameter wheels are arranged at the two ends of the axle; the two small-diameter supporting wheels are mounted in front and back of the vehicle body respectively through retracting mechanisms. Compared with the prior art, the big wheeled vehicle has the following beneficial effects that (1) the large-diameter wheels are in a son-mother structure and are comprehensively controlled by the wheel controller, so as to intelligently realize typical traveling processes of starting, stably driving, accelerating, decelerating, braking and the like; (2) the axle does not rotate, and a driving part and a braking part are integrated in the wheels, so that the structure is compact.

Description

technical field [0001] The invention relates to the field of electric vehicles powered by storage batteries, in particular to a wheeled vehicle with a mother-in-two structure. Background technique [0002] At present, known electric vehicles generally replace the power source with electric motors on the basis of gasoline, diesel and other powered vehicles. Therefore, the structure and driving principle of general electric vehicles are basically the same as gasoline, diesel and other powered vehicles, relying on the rotation of the axle to drive the wheels. Rotate to achieve the purpose of driving. Deceleration and braking are generally achieved by reducing the speed of the motor and using friction. At this time, the energy of friction deceleration is mainly dissipated in the form of heat energy. Moreover, the wheel diameters of general electric vehicles are small, the vehicle body is low, and the trafficability of complex road conditions is limited. Contents of th...
