Abstract (en)

[origin: WO2011095200A2] The invention relates to a vibratory drive of a vibrating roller, comprising an unbalanced-mass vibration generator, which can be used in at least one binding of the vibrating roller operated by an external drive device or advancing device such that the unbalanced-mass vibration generator can be rotated relative to the binding in at least one direction. According to the invention, the unbalanced-mass vibration generator is mechanically coupled to a hydraulic motor, which can be supplied with a pressure medium by a hydraulic pump in order to rotate the unbalanced-mass vibration generator. Furthermore, at least one high-pressure accumulator is provided in order to accommodate pressure medium pumped by the hydraulic motor in a pushing operation. Moreover, the high-pressure accumulator feeds stored pressure medium to the hydraulic motor in a driving operation of the hydraulic motor.
