Abstract

The invention discloses a wheel hub motor distributed time-sharing four-wheel drive electric vehicle chassis configuration, a four-wheel drive electric vehicle and a control method. The wheel hub motor distributed time-sharing four-wheel drive electric vehicle chassis configuration comprises a frame assembly, wherein the frame assembly is provided with a first tire rim assembly, a second tire rimassembly, a centralized motor, a power battery pack, a vehicle controller, a high voltage power distribution box, hub motors and a radiator assembly. The first tire rim assembly is in transmission connection to the centralized motor through a drive shaft and a transmission, and the hub motors are mounted on the second tire rim assembly. A charging machine is electrically connected with the high-voltage power distribution box, and the high-voltage power distribution box is electrically connected with input ends of the vehicle controller and the power battery pack. The vehicle controller is electrically connected with the hub motors, and an output end of the power battery pack is separately connected to the centralized motor and the hub motors through an inverter. The inverter is electrically connected to the high voltage power distribution box. According to the invention, power demands by different driving conditions can be met, and the transmission efficiency is high.

Description

technical field [0001] The invention relates to a chassis configuration of a four-wheel drive electric vehicle, which belongs to the technical field of automobile chassis, and in particular to a chassis configuration of a distributed time-sharing four-wheel drive electric vehicle with hub motors. Background technique [0002] In order to cope with the energy shortage, people pay more and more attention to new energy vehicles. Among new energy vehicles, electric vehicles have less impact on the environment than transmission vehicles, and their prospects are widely optimistic. [0003] The pure electric vehicle is driven by a motor, and the integral drive system is driven by a motor. On the one hand, the larger load greatly increases the size and volume of the motor, which increases the difficulty of installation; The power required by the motor is different. Simple front-drive, rear-drive or four-wheel drive cannot maximize the use of the characteristics of the motor and red...
