FIELD: transport engineering; transmissions and drives. SUBSTANCE: transmission has main hydraulic pump and hydraulic motors of rotary type. Shaft of rotary motor is connected with shaft of positive displacement liquid rotary hydraulic pump whose delivery branch pipe is connected with hydraulic accumulator. Hydraulic accumulator is connected with branch pipes of positive displacement rotary hydraulic motors whose shafts are connected with axle-shafts of wheels installed inside tubular beams of driving axle engaging with disks of vehicle driving wheels. Rotor of hydraulic pump (hydraulic motor) is made cylindrical and it engages with inner surface of housing for closing holes of suction and delivery branch pipes simultaneously. Rectangular flat with radius "R′" smaller than radius "R″" of housing by value of clearance "e" is made on radial surface of rotor. EFFECT: simplified design of transmission. 3 cl, 7 dwg
