    摘要： A four-wheel drive electric vehicle is provided. The vehicle comprises a chassis and a power system. The power system comprises batteries, an electric motor, a DC-DC converter and an electric motor controller which are electrically connected, and the chassis comprises a frame, a transmission/transfer case, a drive shaft, a front axle assembly as well as a rear axle assembly. The transmission/transfer case, the front axle assembly and the rear axle assembly are mounted on the frame. The transmission/transfer case is connected with the rear axle assembly directly and with the front axle assembly via the drive shaft. Under the control of the electric motor controller, the electric motor is driven to rotate by the batteries, whereby a power is transferred from the motor to the transmission/transfer case, and a part of the power is transferred to the rear axle assembly with the other part transferred to the front axle assembly via the drive shaft.

    摘要： The invention discloses a brake auxiliary system having a vacuum container, which comprises an auxiliary power supply, a vacuum pump, a vacuum booster and a vacuum container, wherein the vacuum container and the vacuum booster are both connected with the vacuum pump which supplied power by the auxiliary power supply, a pressure detector and a delay control switch are disposed on the vacuum container, keeping the vacuum degree in the vacuum container within a certain range. The vacuum container of the present invention makes the vacuum pump enable to work intermittently, avoiding frequent start of the vacuum pump when brake and also extending the life of the brake. Because of the pressure detector and the delay control switch, the vacuum inside the vacuum container is kept stable, and the efficiency of vacuum booster is ensured. The invention has low cost, simple and reliable structure, it is green and energy-saving, and it can reduce the energy consumption of the electric car auxiliary power supply and increase the driving miles.
