Road milling machine for working road or ground surfaces

A road milling machine for working road or ground surfaces, comprising:

• a machine frame including a lateral outer side;
• left and right front wheels or crawler tracks, and left and right rear wheels or crawler tracks, supporting the machine frame;
• a milling drum supported from the machine frame;
• left and right height adjustable lifting columns connecting the left and right rear wheels or tracks to the machine frame such that a milling depth of the milling drum is adjustable by adjusting a height of the lifting columns;
• left and right pivoting columns connecting the left and right front wheels or tracks to the machine frame, each pivoting column having a pivot axis;
• left and right steering levers connected to the left and right front wheels or tracks, respectively, so as to steer each of the front wheels or tracks in steering angles about the pivot axes of their respective pivot columns;
• a steering tie rod including a rigid connecting part and an arm projecting from the connecting part, the connecting part coupling the steering levers of the front wheels or tracks to one another for synchronous adjustment of the steering angles;
• at least one steering actuator including a free end coupled to the arm of the steering tie rod to adjust the steering angles;
• and
• wherein the front wheels or tracks are steerable between first and second end positions for a direction of travel to the right or left, and the steering tie rod has first and second curved sections configured such that in the first end position the left pivoting column is received in the first curved section and in the second end position the right pivoting column is received in the second curved section.
