Abstract

The present invention relates to a multi-motor driving structure of motor vehicle, and comprises a motor, a wheel hub shell, a wheel hub end shield and a motor shaft. The wheel hub end shield is fixedly connected with the wheel hub shell; the center of the wheel hub end shield is provided with a motor shaft hole; the motor shaft passes through the central shaft holes of two end shields; the motor is fixed on the motor shaft; the structure is provided with a plurality of motors, which are symmetrically arranged along the motor shaft; the motors comprise a shell, a stator and a rotor; the stator is fixedly connected with the shell; the shell and the stator are fixedly connected with the motor shaft; the rotor is positioned in the shell by a bearing and is arranged in the stator; the output shaft of the rotor is connected with a one-way bearing; an idle wheel is sleeved on the motor shaft by a bearing housing, and meshes the one-way bearing; the inner side of the right end shield is provided with a ring gear; and the inner teeth of the ring gear meshes the one-way bearing. The multi-motor driving structure can increase the running mileage of the motor vehicle and increase the output torque.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to a multi-motor drive structure of the electric vehicle. Background technique [0002] The current electric vehicles are all driven by a single motor. The driving motor is usually set in the hub shell, and the driving motor transmits power to the hub through the hub end cover. Due to the weight and volume constraints of the electric vehicle, the power of the driving motor cannot be very high. Large, generally there is a large motor current when starting, and the starting driving force is insufficient, so the starting acceleration performance of the electric vehicle is not good; in addition, when driving on a sloped road, the above-mentioned insufficient power also exists. Contents of the invention [0003] The purpose of the present invention is to provide a multi-motor drive structure for an electric vehicle. The controller of the electric vehicle controls the working conditions of the mul...
