FIELD: transport engineering; electric traction system of articulated vehicles with two or more driving axles and self contained hydropneumatic energy accumulator. SUBSTANCE: vehicle has two driving axles one of which has traction electric motor connected to contact system through electronic voltage regulator, accelerating and brake pedals with pedal travel pickups, and control unit. Second axle is furnished with hydraulic machine of pump-motor type with working fluid control mechanism, low-pressure reservoir, hydropneumatic accumulator, electrically controlled valve, pressure pickup and clutch. EFFECT: increased efficiency of regeneration of braking energy, possibility of riding at no contact system or no voltage in system. 2 dwg
