Abstract:
1. A road milling machine for working road or ground surfaces, comprising: a machine frame; left and right front wheels or crawler tracks, and left and right rear wheels or crawler tracks, supporting the machine frame, wherein one of the left or right front wheels or tracks is offset in front of the other of the left or right front wheels or tracks in a direction of travel; a milling drum supported from the machine frame between the rear wheels or tracks, the milling drum including an end located substantially flush with a lateral outer side of the machine frame such that the lateral outer side defines a zero-clearance side to enable milling close to obstacles; 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 rigid connecting part coupling the steering levers of the front wheels or crawler tracks to one another for synchronous adjustment of the steering angles; and at least one steering cylinder configured to adjust the steering angles.
