Patent number: 7976106Abstract: The invention relates to a self-propelled civil engineering machine, in particular a road-milling machine, a road recycler, or a road stabilizer, having a frame carried by a set of running gear, a working unit for performing work required for the civil engineering operation, and in particular a working drum, and a drive unit carried by the frame of the machine, to drive the working drum. A power transmitter is used to transmit the driving power from the drive unit to the working unit. The drive unit of the self-propelled civil engineering machine has a first and a second drive engine, the power transmitter being so designed that the driving powers coming from the first and the second drive engines can be transmitted to the working unit together.Type: GrantFiled: April 16, 2008Date of Patent: July 12, 2011Assignee: Wirtgen GmbHInventors: Christian Berning, Dieter Simons, Peter Busley

Publication number: 20110163589Abstract: Self-propelled road milling machine with a milling drum housing including a side with a power take-off to transmit rotational motion to a milling drum mounted in an axially sliding way and replaceable from the side opposite the side of the power take-off. The milling drum is rotated by a reduction gear. The reduction gear is mounted at the end of a hollow spacer. A transmission shaft is present in the hollow spacer. The hollow spacer connects the wall of the housing on the side of the power take-off to a support flange of the reduction gear, which is connected to a spacer. The spacer engages a movable flange of the reduction gear, and connects to fastening elements and the support on the wall of the housing. The support flange and the hollow spacer are static with respect to the rotary movement of the milling drum.Type: ApplicationFiled: January 10, 2011Publication date: July 7, 2011Inventors: Antonio Cipriani, Enio Cavallini
