The invention provides a power distribution device for an electric vehicle, which can distribute power larger than power of front wheels to rear wheels and obtain stable vehicle behavior during braking. This power distribution device for an electric vehicle is mounted on an electric vehicle provided with front wheels, rear wheels, an electric motor for outputting power for travel, and a mechanical brake for applying braking force to at least the front wheels. Furthermore, the device is provided with: a power distribution mechanism that distributes power output from the electric motor to the front wheels and the rear wheels; and a controller that controls the power distribution mechanism, the power distribution mechanism including: a first clutch capable of fixing a power distribution ratio during straight movement to a first distribution ratio; and a second clutch capable of fixing the power distribution ratio during straight movement to a second distribution ratio, and the controller sets the second clutch to an engaged state and sets the first clutch to a semi-engaged state during regenerative braking of the electric vehicle.

    本发明提供能够向后轮分配比前轮的动力更大的动力,并且在制动时获得稳定的车辆的行为的电动车辆的动力分配装置。该装置是搭载于具备前轮、后轮、输出行驶用的动力的电动马达、至少给前轮带来制动力的机械制动器的电动车辆的电动车辆的动力分配装置。而且,该装置具备:动力分配机构,其向前轮和后轮分配从电动马达输出的动力;控制器,其控制动力分配机构,动力分配机构包括:第一离合器,其能够将直行时的动力分配比固定为第一分配比;第二离合器,其能够将直行时的动力分配比固定为第二分配比,控制器在电动车辆的再生制动时,将第二离合器设为接合状态,并将第一离合器设为半接合状态。
