This integral unit is available with its small outline dimensions, minimal mass and unit function improvement. The unit consists of a shaft (1) stored in a housing (4) and a hydraulic brake back flange. The back and the front support cover of the hydraulic motor with front distribution of hydraulic fluid, respectively the distributor housing of the hydraulic motor with radial distribution of hydraulic fluid are integrated in one part (5), with a radial seal (29, 44) for a shaft (1) placed in it, separates the drain chambers of the brake and the hydraulic motor. A control valve block (33), including at least a hydraulic shuttle valve (35) is mounted on the hydraulic motor connecting surface, whereupon between the shuttle valve (35) and the brake working space (11), an internal passageway (36, 45) or a pipe line (37) for sending hydraulic control signal is made.
