Road Milling Machine For Working Road Or Ground Surfaces, As Well As Method For Steering A Road Milling Machine

摘要

A road milling machine with a machine frame supported by a chassis with one front axle and one rear axle with wheels or crawler tracks, with a milling drum mounted at the machine frame to rotate between the rear wheels, where said milling drum ends nearly flush with a zero-clearance side, it is provided that the wheels or crawler tracks of the front axle as seen in the direction of travel are arranged offset from one another in such a fashion that one of the front wheels or tracks is arranged in front of the other front wheel or crawler track as seen in the direction of travel.

主权项

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 directly or indirectly connected to at least one of the front wheels or tracks to adjust the steering angles.
