摘要:
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. With the design of drive according to the invention, a particularly space-saving construction is obtained for the drive and this allows the power of the drive unit to be increased without having to exceed the preset width for transport of the self-propelled civil engineering machine.

The invention relates to a road-building machine whose left front wheel (4) or caterpillar, right front wheel (6) or caterpillar, left rear wheel (8) or caterpillar and right rear wheel (10) or caterpillar are connected to the road-building machine chassis by means of an actuating element and are height-adjustable with respect to the road-building machine frame. According to said invention, different actuating elements are rigidly connected to the road-building machine chassis and forcedly coupled to each other in such a way that the left front wheel (4) or caterpillar and the right rear wheel (10) or caterpillar are height-adjustable in the same direction and with respect to the right front wheel (6) or caterpillar and the left rear wheel (8) or caterpillar are adjustable in the opposite directions. The all wheels (4, 6, 8, 10) or caterpillars are equally height-adjustable. The inventive road-building machine provides a high operational stability, the improved compensation of the adjustment of lateral hindrance inclination of the road-building machine and the irregularities in the longitudinal direction thereof.
