Abstract: The invention relates to a valve assembly (50) of a radial piston hydraulic apparatus (1). Said apparatus includes a cylinder block (4) insertable onto a shaft (2) by translation. Said assembly (50) includes: a valve (51) in contact with said cylinder block (4); a valve train cover (52); and a first (541) and second (542) chamber that are defined, respectively, by a first (511, 521) and second (512, 522) space that are located at the interface between said valve (51) and said valve train cover (52), and are intended for the pressurized fluids that enable the conversion of pressure and/or mechanical stress. Said assembly (50) includes an additional section (54) defined by a third space (541, 542) located at the interface between said valve (51) and said valve train cover (52). Said section (54) is intended for receiving a pressurized fluid such as to enable the cylinder block (4) to be inserted onto the shaft (2).

Abstract: An assembly (20) comprising a radial piston hydraulic motor (10), comprising a fixed housing (15), a shaft (14) that can be driven in rotation by the hydraulic motor (10), a wheel hub (30) comprising a hub barrel (31) that engages on the shaft (14), a bearing (40), a bearing support (41), in which the bearings (40) are housed between the hub barrel (31) and the bearing support (41) of the hydraulic motor (10), the bearing support (41) forming part of the housing (15), such that the bearing function is carried out by the housing (15), the shaft (14) supporting only the weight of same and having only a torque function.
