Road milling machine to the machining of road surfaces, as well as a method for the pivoting of a running gear of a road milling machine

摘要

Road milling machine (1) for processing of road surfaces, with a controller for the driving, steering and being in milling mode, with a via lifting columns (3) is vertically adjustable machine frame (2), with a running gear with at least rear in the direction of travel in each case with a drive (36) running gears (4) is provided at the lower ends (18) of the a longitudinal axis (20) of the lifting columns (3) are arranged, with a on the machine frame (2), arranged around a working roll axis (7) rotatable working roll (5), around a parallel to the longitudinal axis (20) of a lifting column (3) extending pivot axis (30) of pivotal arm (6), which a rear lifting column (3) with the machine frame (2) and connects a drive (4) from a first, relative to the machine frame (2), laterally projecting, outer end position (12) in a second inner end position (14) and back again, with a steering device (22) for the pivoting drive (4), having a first, on the swivel arm (6) with a second drive device, acting on the steering device (22) with the drive device, a steering angle of the carriage (4) is adjustable, and is provided that the drive mechanism (36) for the pivoting drive (4), the first drive means for the pivoting movement of the pivot arm (6) with permanent contact with the floor of the carriage (4) forms.
