Abstract:
A vibratory drive of a vibrating roller includes an unbalanced-mass vibration generator configured to be used in at least one drum of the vibrating roller. The vibrating roller is operated by an external drive device or advancing device such that the unbalanced-mass vibration generator can be rotated relative to the drum in at least one direction. The unbalanced-mass vibration generator is mechanically coupled to a hydraulic motor, which is configured to be supplied with a pressure medium by a hydraulic pump to rotate the unbalanced-mass vibration generator. At least one high-pressure accumulator is provided to accommodate pressure medium pumped by the hydraulic motor in a pushing operation. The high-pressure accumulator feeds stored pressure medium to the hydraulic motor in a driving operation of the hydraulic motor.
