Abstract

The invention discloses a wheeled vehicle self-adaptive load-bearing and driving device and a control method thereof. The wheeled vehicle self-adaptive load-bearing and driving device comprises a vehicle frame, an adjustable load-bearing device, an auxiliary load-bearing device and a load-bearing and driving control system, wherein the auxiliary load-bearing device comprises a first shock-reduction universal foot wheel, a second shock-reduction universal foot wheel, a first shock-reduction directional foot wheel and a second shock-reduction directional foot wheel, and the first shock-reduction universal foot wheel, the second shock-reduction universal foot wheel, the first shock-reduction directional foot wheel and the second shock-reduction directional foot wheel are arranged on four corners of the vehicle frame in equal height. The adjustable load-bearing device is mounted on the vehicle frame and located in the gravity center of a vehicle. By means of the wheeled vehicle self-adaptive load-bearing and driving device, under the same whole-vehicle load condition, requirements on driving force are lowered, motor power and battery capacity are reduced, energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to a control method for optimizing the load borne by each wheel of a wheeled electric vehicle in real time so as to drive effectively by utilizing the preload adjustment of an auxiliary bearing device and the active load adjustment of an adjustable bearing device, and belongs to the field of automatic conveying equipment. Background technique [0002] Wheeled electric vehicles usually use the on-board battery to provide operating energy, and the motor drives the wheels to drive the vehicle. Batteries have a low energy density compared to various fuels that are burned to generate energy. In order to drive wheeled vehicles to transport a certain load within a certain working time, electric vehicles generally need to carry a battery pack composed of multiple batteries to provide sufficient instantaneous discharge current and long power supply time. However, the increase in the number of batteries also increases the weight of the ele...
