The invention discloses an electric auxiliary driver, an electric auxiliary driving system and a new energy electric automobile, and belongs to the technical field of automobile parts. The electric auxiliary driver comprises a speed reducer assembly and a motor assembly. The speed reducer assembly comprises an overrun clutch, an intermediate shaft, an output shaft, an input shaft and a speed reducer shell, the overrun clutch sleeves one end of the intermediate shaft and is fixedly connected with the intermediate shaft, the other end of the intermediate shaft is in meshing transmission with the output shaft, and the input shaft is in meshing transmission with the overrun clutch; and one end of the input shaft is coaxially and fixedly connected with a motor output shaft in the motor assembly. When the torque of the output shaft is larger than that of the input shaft, the overrunning clutch is in an overrunning state, and when the torque of the input shaft is larger than that of the output shaft, the overrunning clutch is in a combined state. By the adoption of the scheme, when the automobile is reversely dragged, energy consumption of the whole automobile cannot be increased, resources can be saved, and abrasion among the input shaft, the middle shaft and the output shaft is reduced.

    本申请公开了一种电动辅助驱动器、电动辅助驱动系统和新能源电动汽车,属于汽车零部件技术领域。该电动辅助驱动器包括减速器组件和电机组件;减速器组件包括超越离合器、中间轴、输出轴、输入轴和减速器壳体,超越离合器套装在中间轴的一端,且与中间轴固定相连,中间轴的另一端与输出轴啮合传动,输入轴与超越离合器啮合传动,且输入轴的一端与电机组件中的电机输出轴同轴固定相连。当输出轴的扭矩大于输入轴的扭矩时,超越离合器处于超越状态,当输入轴的扭矩大于输出轴的扭矩时,超越离合器处于结合状态。采用该方案,当汽车出现反拖现象时,不会增加整车的耗能,有利于节约资源,而且减少了输入轴、中间轴、以及输出轴之间的磨损。
