ABSTRACT:
The vibrating roll apparatus has a hydrostatic roll body drive drive. An internal-combustion engine drives a pump unit which includes an inclined disk pump of variable displacement and a filling pump. At least one hydraulic drive motor which is fed a pressurized medium by the inclined disk pump powers the hydrostatic roll body drive. An eccentric body in the roll body of the vibrating roll is driven by a mechanical power transmission device with a built-in clutch also powered by the internal-combustion engine. According to the invention the clutch is flanged to the pump unit and provided with a hydrostatically-operated clutch mechanism, which is connectable with the pressurized side of the filling pump by a clutch valve for engagement of the clutch. In this way a space-saving compact form for the drive for the eccentric body including means for its control with optimum conditions for clutch operation is attained.
