Hydromechanical dredger drive unit - has slow radial piston motor with rotating housing, and fast axial piston motor

摘要

The unit has two motors, one of which may be switched off. This motor is formed as an internally charged slow radial piston motor (8) with turnable housing (7). The other motor is formed as a fast axial piston motor (1). The output side of this motor is connected to the housing of the radial piston motor. The housing is non-turnably connected to a take-off element of the hydromechanical drive unit. The radial piston motor is a fixed displacement motor. The axial piston motor has a constant pressure regulator. The housing of the radial piston motor has an external toothing (6), which meshes with a gear (4). The gear is non-turnably fastened to the take-off shaft (3) of the axial piston motor. USE/ADVANTAGE - Central power divider for mobile dredger, etc. is of simple construction, economical to mfr. and is of improved efficiency.
