ABSTRACT:
A hydraulic motor comprising a casing, a reaction member, a cylinder block, an inner fluid distributor valve fast with the casing with respect to rotation about the axis of the motor and a driving shaft extending inside the casing coaxially to said axis. The motor is a low-speed, high-torque motor and comprises, disposed inside the casing, a coupling member fast in rotation with the cylinder block, a step-up gear, first and second mechanical engagement means for connecting the coupling member and the driving shaft and, respectively, the coupling member and the step-up gear, in rotation. The coupling member is mobile between a first and a second position in which the first and the second engagement means are selectively activated and de-activated. The motor comprises means for controlling the displacement of the coupling member between its positions. The driving shaft is capable of constituting a portion of the main shaft of the transmission of a vehicle.
