The invention relates to a dual-motor redundant drive mechanism and a vehicle driving wheel assembly, belongs to the technical field of mechanical transmission, and particularly relates to a redundant drive and control technology of a vehicle. According to the dual-motor redundant drive mechanism, two motors drive two bevel gears to input power through two sets of worm pairs with the reverse transmission self-locking characteristic, power is output after combination of a two-degree-of-freedom gear train, dual-motor and rated-power drive is achieved, when one motor breaks down, energy application of the motor fails, the worm pair conducts reverse transmission self-locking, and the other worm pair conducts reverse transmission self-locking. The other motor is in single-machine redundant driving; the vehicle driving wheel assembly formed by the dual-motor redundant driving mechanism realizes the redundant driving of the driving of the light vehicle, and ensures the driving safety of the vehicle.
本发明涉及一种双电机冗余驱动机构及车辆驱动轮总成,属于机械传动技术领域,特别涉及车辆的冗余驱动、控制技术;双电机冗余驱动机构由两个电机通过两组具备反向传动自锁特征的蜗杆副驱动两个锥齿轮输入动力,由双自由度轮系合成后输出动力,实现双电机、额定功率驱动,一个电机故障时,该电机施能失效、该组蜗杆副反向传动自锁,另一个电机单机冗余驱动;由双电机冗余驱动机构所形成的车辆驱动轮总成,实现了轻型车辆行驶冗余驱动,保障车辆的行驶安全性。
