The stepless transmission is used in the drives of vehicles with accumulation of energy. It offers increased energy storage and reliability. The transmission contains a hydroexchange block consisting of a hydropump (13) connected with the main energy source (1) and hydraulically connected via a three-position manually operated distributor (47) with a controllable hydromotor (14). The hydromotor (14) is connected with the driving bridge (3). The controllable hydropump (13) and one feeding pump (15) are connected through a coupling device (5) also with the kinetic energy accumulator (2). The feeding pump (15) is hydraulically connected through the first, second and third two-positioned distributors (29, 31 and 33) with the slave cylinder (23) which regulates the volume of the hydropump (13). The third distributor (33) is mechanically connected with the gas pedal (7), the brake pedal (8) and hydraulically - with the chamber (23a) of the cylinder (23) and the closed circuit (16) via the fourth two-positioned distributor (39). The closed circuit (16) is hydraulically connected with the second slave cylinder (26) which regulates the working volume hydromotor (14) via a reduction valve (22) and fifth, sixth and seventh two-position distributors (41, 43 and 45). The fifth and sixth distributors (41 and 43) are hydraulically controlled by the closed circuit (16) and the chamber (23a) of the cylinder (23), while the reduction valve (22) is controlled by the gas pedal (7) and the braking pedal (8).
