Four-drive electric car

Abstract

The invention discloses a four-drive electric car comprising a car body, a chassis and a power device, wherein the power device comprises an accumulator battery, a motor, a DC-DC converter and a motorcontroller; the chassis comprises a car frame, a speed-change torque divider, a transmission shaft, a front axle assembly and a rear axle assembly, wherein the speed-change torque divider, the frontaxle assembly and the rear axle assembly are arranged on the car frame, and the transmission shaft is connected between an output shaft of the speed-change torque divider and the front axle assembly;the accumulator battery, the motor, the DC-DC converter and the motor controller are electrically connected, the accumulator battery provides electric power to enable the motor to rotate and transmitpower to the speed-change torque divider, the speed-change torque divider transmits a part of the power to the front axle assembly and finally transmits the power to a left front wheel and a right front wheel through a front axle left half shaft and a front axle right half shaft; the output shaft of the speed-change torque divider is connected with the rear axle assembly, and the other part of thepower is transmitted to a rear axle rear half shaft and a rear axle right half shaft through the output shaft by the rear axle assembly and then transmitted to a left rear wheel and a right rear wheel.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to a four-wheel drive electric vehicle. Background technique [0002] At present, due to the occurrence of the energy crisis and the increasing emphasis on environmental protection, countries around the world have begun to develop pure electric vehicles, and there are more and more styles of electric vehicles. However, most of the current pure electric vehicles are two-wheel drive. Under certain circumstances, such as the passability, climbing performance, straight-line driving stability, starting and acceleration performance of wet and snowy roads and uneven roads, etc., cannot meet the needs of consumers for four-wheel drive electric vehicles. Contents of the invention [0003] The problem to be solved by the present invention is to provide a four-wheel drive electric vehicle with compact structure and reasonable spatial arrangement. [0004] The technical scheme adopted in the present in...
