A hydraulic transmission circuit is provided having at least two elementary hydraulic motors, each having a secondary enclosure and a main duct for fluid feed and a secondary enclosure and a main duct for fluid discharge. A fluid distributor distributes fluid from the main ducts to the elementary motors via the secondary enclosures. A control system controls the elementary motors. Valves connecting the fluid distributor to the secondary enclosures of the first motor put a secondary enclosure into communication with a main duct independent of an operating mode of any other elementary motor.

A cylinder block includes: a plurality of cylinder bores including respective openings formed on a piston insertion end surface of the cylinder block, pistons being inserted in the respective cylinder bores and being configured to reciprocate and slide in the respective cylinder bores when the cylinder block rotates; and a cooling portion, wherein the cooling portion includes a plurality of cooling holes each formed between the adjacent cylinder bores and extending from the piston insertion end surface in an axial direction of the cylinder block.

A motor vehicle structure includes two left and right bell-shaped suspension element supports arranged inside a front compartment close to a bulkhead of the vehicle. The suspension element supports are respectively adjacent to side walls of the front compartment. Each of the suspension element supports includes an internal face opposite the side wall. The structure also includes left and right spacers that extend respectively between the left and right suspension element supports and the rigid cross member, in a substantially longitudinal direction. The spacers are respectively anchored to the internal faces of the two suspension element supports. The spacers each have a skirt-shaped edge that can be applied to the suspension element supports, and a folded edge extending between a free end and an opposing attachment end to be joined to the cross member. The spacers include a central portion joining the folded edge and the skirt-shaped edge together.
