SELF-PROPELLED, PREFERABLY ONE-AXLE, MANUALLY STEERABLE AND CONTROLLABLE WORKING MACHINE FOR DISPLACING AND OPERATING ATTACHED WORK TOOLS

摘要

A self-propelled, preferably uniaxial, manually steerable and steerable working machine (1) grown for Moving and operating tools or attached to vehicles, consists of a on a chassis (4) constructed, a drive train (18) associated with the drive motor (2) provided with one for propulsion of the working machine (1) certain hydrostatic drive unit (3) is connected, at least one with the drive motor (2) detachable and controllable hydraulic pump (31, 34) and with this line connected (in a direction transverse to the direction of movement extending drive axis 5 ) wheels at each end mounted (6, 7) associated with the hydraulic motors, and said (2) for driving a front side of the chassis (4) mounted working machine is formed with a shiftable working shaft (13), such that in said drive motor ( (2), the hydrostatic drive unit (3) and the working shaft 13) connecting the drive train (18) arranged, at least one hydraulic pump (31, 34) and the working shaft (13) each having an independent one from the other and disengageable clutch (23, 48) is connected upstream.
