ABSTRACT:
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.
