Publication number: 20220220675Abstract: The disclosure relates to a road finishing machine with a screed for producing a paving layer, wherein the screed includes at least one compacting unit for precompacting paving material supplied to the screed. The compacting unit includes at least one eccentric bushing mounted on an eccentric shaft supporting the same at a desired angle of rotation to thereby continuously variably set a desired tamper stroke of a tamper bar of the compacting unit. For rotating the eccentric bushing on the eccentric shaft, an adjusting mechanism mounted spaced apart from the eccentric shaft and at least partially rotatable along with a rotary motion of the eccentric shaft can be activated. Furthermore, the disclosure relates to a method for a continuously variable tamper stroke adjustment at a compacting unit of a road finishing machine.Type: ApplicationFiled: January 14, 2022Publication date: July 14, 2022Applicant: JOSEPH VOEGELE AGInventors: Klaus BERTZ, Ralf WEISER, Tobias NOLL, Christian PAWLIK

Patent number: 9487924Abstract: A tamper of a screed includes a tamper bar secured to a connecting rod in which an eccentric bushing is rotatable. The eccentric bushing is adapted to be rotationally displaced on an eccentric section of a drive shaft relative to the eccentric section and to be rotationally coupled with the eccentric section at relative rotational positions defining different stroke lengths of the tamper bar. A changeover between the rotational positions is accomplishable by a reversal of the direction of rotation of the drive shaft. The eccentric bushing is adapted to be locked at each respective rotational position by means of a locking and/or coupling device against inadvertent displacement from the respective rotational position. The locking and/or coupling device is adapted to be released and/or engaged automatically or by remote control for effecting a changeover from one rotational position to the next.Type: GrantFiled: January 6, 2015Date of Patent: November 8, 2016Assignee: JOSEPH VOEGELE AGInventors: Klaus Bertz, Ralf Weiser

Patent number: 9260827Abstract: The invention relates to a road finishing machine with a controllable longitudinal conveyor device and a transverse conveyor device for mixed laying material disposed in the rear in the direction of motion. The road finishing machine furthermore comprises a control unit for adjusting a delivery rate of the longitudinal conveyor device and/or the transverse conveyor device. The control unit is connected with a sensory mechanism for determining a mixed laying material quantity or rate and adjusts the delivery rate in response to a signal from the sensory mechanism representing the mixed laying material quantity or rate. The control unit can be pilot controlled in response to laying parameters by a pilot control unit.Type: GrantFiled: January 28, 2013Date of Patent: February 16, 2016Assignee: JOSEPH VOGELE AGInventors: Klaus Bertz, Tobias Noll, Ralf Weiser, Alessandro De Santis
