Abstract
The assembly of a hydraulic motor and of a brake, comprising a frame; a cylinder-block mounted to rotate via a bearing and provided with a communication face; a fluid distributor valve provided with a distribution face in abutment against the communication face of the cylinder-block. A plurality of braking members are provided, some fast with the frame, the others fast with a brake shaft itself fast in rotation with the cylinder-block. An axial thrust braking member and a brake-release jack are coupled between the frame and the brake shaft. The brake shaft is fast in translation with the cylinder-block in the direction opposite that of the thrust force producing abutment of the distribution face against the communication face.
