FIELD: mechanical engineering.
SUBSTANCE: invention relates to traction systems for vehicles. The vehicle comprises working media of a pneumatic system consisting of a vertical air piston pump. The vertical air piston pump consists of a body which is hermetically sealed to the bottom of the vehicle body and of several air working chambers which are separated by a barrier and are fixed to each other. A hermetically sealed bottom is attached to the lower part of the body. Pistons are arranged in air working chambers and are fixed on a rod, the end of which is fixed to the vehicle axle so as to be able to move freely along the axle. The intake of air mass from the atmosphere into the air working chambers is carried out through the atmospheric windows in the wall of the body, the discharge of the working medium from the air working chambers of the body is carried out under pressure through inner valves through a pipeline into an air reservoir for accumulating the energy of the compressed air. The pneumatic engine of rotates the shaft of the electric generator by the compressed air energy which generates electrical energy which is used to charge traction batteries.
EFFECT: increased run of an electric vehicle.
