Hydromechanical wheel-drive mechanism particularly for driving the wheels of a civil engineering works vehicle

摘要

a) Hydromechanical wheel-drive mechanism particularly for driving the wheels of a civil engineering works vehicle. b) Mechanism characterised in that the planetary gear train is arranged concentrically to the axial-piston engine inside its axial extent and exhibits an element (17) coming into engagement on the cylinder drum (7) which drives the hub (2), the cylinder drum (7) of the axial-piston engine being connected, without interposition of an output shaft, to a rotating element of the planetary gear train and being supported by a bearing (3) used to receive, at the same time, the transmission forces of the axial-piston engine and the forces acting from the outside on the wheel-drive mechanism located between the hub (2) and the hub carrier (1).
