Patent number: 11913178Abstract: An oscillation module for a compacting roller of a soil compactor includes a plate-like carrier, at least two oscillation mass units supported on the carrier at a distance from one another, and an oscillation drive motor supported on the carrier. The carrier has a connection formation for firmly connecting the carrier to a carrier structure of a compacting roller. Each oscillation mass unit includes an imbalance mass rotatably supported on the carrier about an oscillation axis of rotation. Each imbalance mass of each oscillation mass unit can be driven by the oscillation drive motor for rotation about the respectively assigned oscillation axis of rotation.Type: GrantFiled: January 4, 2022Date of Patent: February 27, 2024Assignee: HAMM AGInventor: Peter Janner

Patent number: 11781278Abstract: An unbalance arrangement for a compactor roller of a soil compacter includes a first unbalance mass unit rotatable around an unbalance axis of rotation having a first center of mass eccentric with respect to the unbalance axis of rotation, a second unbalance mass unit rotatable around the unbalance axis of rotation having a second center of mass eccentric with respect to the unbalance axis of rotation, an unbalance drive for jointly driving the first unbalance mass unit and the second unbalance mass unit to rotate around the unbalance axis of rotation, and a phase position adjustment unit for adjusting a phase position of the first center of mass with respect to the second center of mass around the unbalance axis of rotation. The phase position adjustment unit includes a spur gear arrangement in the torque transmission path between the unbalance drive and the first unbalance mass unit or the second unbalance mass unit.Type: GrantFiled: April 16, 2021Date of Patent: October 10, 2023Assignee: HAMM AGInventors: Gerhard Wolfrum, Peter Jänner
