[0002] The electric vehicle reducer is a device whose main function is to reduce the speed and increase the torque to meet the needs of vehicle driving. Unlike the gearbox of traditional cars, pure electric vehicles do not have a gearbox in the traditional sense, but use a device called a reducer. This reducer converts the high speed and high torque generated by the electric motor into low speed and high torque through the meshing of gears, allowing the vehicle to move. When the electric vehicle accelerates, the electric motor will generate a high speed. At this time, the reducer will convert the high speed into a low speed and increase the torque to meet the needs of vehicle driving. When the electric vehicle decelerates or brakes, the reducer will convert the vehicle's kinetic energy into electrical energy and store it in the battery, thereby realizing energy recovery.
