The invention discloses an integral rear-axle device of a rear-wheel-driven electric vehicle. The integral rear-axle device comprises a rear axle tube, a left bracket for fixing one end of the rear axle tube, and a right bracket for fixing the other end of the rear axle tube, wherein the left bracket is cast into a whole by cast steel, and the right bracket is cast into a whole by cast steel; a hub unit mounting hole, a rear steel plate spring mounting surface and a rear shock absorption mounting hole are integrated on the left bracket; a hub unit mounting hole, a rear steel plate spring mounting surface and a rear shock absorption mounting hole are integrated on the right bracket; the wheel axis on the two hub unit mounting holes is parallel to the tube axis of the rear axle tube, and is positioned in front of the tube axis of the rear axle tube; rear buffer block limiting plates which are opposite to the corresponding rear steel plate spring mounting surfaces and can limit rear buffer blocks respectively on rear steel plate springs of the corresponding rear steel plate spring mounting surfaces are fixedly connected to the left bracket and the right bracket respectively. According to the integral rear-axle device disclosed by the invention, the problem that a conventional rear axle of a rear-wheel-driven electric vehicle with a rearmounted motor cannot be arranged is solved; the hub unit function, the buffering and limiting function of the rear steel plate springs, and the rear shock absorption assembling function are realized; the integral rear-axle device bears the weight of the rear axle, and besides, the performance of the motor can be avoided; the integral rear-axle device is high in degree of integration.
