Abstract

The invention discloses a dual-motor drive electric wheel system for an electric motor coach. The dual-motor drive electric wheel system comprises two hub motors, rims, motor housings, a motor shaft, three brakes, a planet mechanism and the like. The rims are connected with a planet carrier supported on a rotor support through bolts; a rotor of the first hub motor is fixed to the rotor support and is supported on the motor shaft through a bearing; a brake caliper of the first brake is fixed to the first hub motor housing, and a brake disk is installed on the rotor support. A stator of the second hub motor is installed on a stator support solidified to the motor shaft, a brake caliper of the second brake is fixed to the motor shaft, and a brake disk is fixed to the second hub motor housing. A gear ring of the planet mechanism is fixed to the second hub motor housing. A wheel brake caliper is fixed to the first hub motor housing, and a brake disk is fixed to the planet carrier. According to the dual-motor drive electric wheel system, through the cooperative usage of the dual motors, the brakes and the planet mechanism, the functions of fixed transmission ratio transmission and stepless speed regulating can be achieved.

Description

technical field [0001] The invention relates to a wheel hub motor drive system for an electric passenger car, in particular to a double motor drive electric wheel system. Background technique [0002] Since the 21st century, environmental problems and energy crises have plagued mankind more and more, and more and more attention has been paid to the emission of the automobile crisis. Electric vehicles, as a new energy vehicle, will become an inevitable trend in the future development of automobiles. will recede from the stage of history. The structure type of in-wheel motor direct drive system is increasingly becoming the development direction, and in-wheel motor has become the research focus in the field of electric vehicles. For electric buses, it is difficult to meet the requirements of the motor for speed and torque according to the characteristics of the hub motor, and it is necessary to design a reducer to meet the performance requirements of the vehicle. Passenger ca...
