Road milling machine (10) are employed to mill off defective or worn road surfaces (11) from the road bed. During operations some wheels may run along an already milled track (22), with the wheels running on the milled track (22) being disposed at a lower level. To compensate for this difference in height, known road milling machines (10) have a full-floating front axle. This causes the front wheels (14) to run at a tilt, which in particular hampers the steering properties in known road milling machines (10). The invention proposes that the front wheels (14) be assigned to a parallelogram steering axle (23). The parallelogram steering axle (23) guides the front wheels (14) such that their wheel axles (48) remain in constant horizontal alignment even when the front wheels (14) run at different heights, thus avoiding any impaired steering of the road milling machine (10) even when a front wheel (14) runs on a lower, milled track (22).
