Patent number: 8944517Abstract: A self-propelling construction machine has a machine frame, an operating drum and a drum housing enclosing the operating drum. The drum housing is closed off by a front and/or rear sealing element and/or lateral sealing element. The construction machine has a mechanism for raising and lowering the at least one sealing element. A measuring unit is configured so that the measuring unit measures the forces acting on the sealing element when the sealing element encounters an obstacle. A control unit generates a control signal for raising the sealing element when the force measured by the measuring unit is larger than a predetermined limit value, so that the sealing element is raised.Type: GrantFiled: March 7, 2013Date of Patent: February 3, 2015Assignee: Wirtgen GmbHInventors: Dirk Franzmann, Christian Berning, Herbert Ley, Cyrus Barimani, Günter Hähn

Patent number: 8939515Abstract: The invention relates to a road milling machine, with a milling drum housing partially surrounding a milling drum, wherein the opening between the milling drum housing and the surface of the material to be milled can be closed off by a hold-down device. The distance between the axis of rotation and the hold-down device increases in the specified direction of rotation of the milling drum at least over a section of the gap between the milling drum and the hold-down device. The particular configuration of the hold-down device leads to an improvement in transport of the milled material to the transport arrangement. The gap width increasing in the direction of rotation of the milling drum improves material flow with a relatively small power requirement and relatively low wear of the milling drum.Type: GrantFiled: March 8, 2013Date of Patent: January 27, 2015Assignee: Wirtgen GmbHInventors: Dirk Franzmann, Christian Berning, Herbert Ley, Cyrus Barimani, Günter Hähn
