Embodiment Construction

[0043] figure 1 A road milling machine for milling roads is shown with a self-propelled chassis comprising a steerable front axle 6 with two front wheels 10 , 12 and two mutually independent rear wheels 14 , 16 . It will be appreciated that the wheels 10 to 16 may be replaced in whole or in part by tracks.

[0044] The chassis supports rack 8, according to figure 2 , on the frame 8 the operating platform 4 is located on the so-called zero clearance side 24 of the road construction machine. The height of the rear wheels 14 , 16 is adjustable via a lifting column 48 in order to be able to use said lifting column 48 to adjust the working depth of the milling drum 20 .

[0045] With the front end of the milling drum 20 on the zero-clearance side, the milling drum 20 is almost flush with the zero-clearance side 24 of the frame, making it possible to work close to the edge on the zero-clearance side 24 of the road milling machine. To achieve this effect, the wheel 16 is pivoted ...

Abstract

A road milling machine for processing roads or ground comprising a frame (8) supported by a chassis having a front (6) and rear (7) axle with wheels or tracks; a milling drum (20) The wheels of the front axle (6) or the steering rods (36) of the track are coupled to each other in an articulated manner via a rigid connecting part (40) for synchronous adjustment of the steering angle; the steering hydraulic cylinder (44) adjusts the wheels or the steering angle of the tracks, wherein said steering cylinder (44) is directly or indirectly articulated relative to said frame (8) at a fixed point (42) and at least directly or indirectly connected to one wheel support (32) Coupling; as viewed in the direction of travel, the wheels or tracks of the front axle (6) are arranged offset relative to each other so that the wheels (10, 12) on the inner side, or on the zero clearance side ( The wheels (12) or tracks on 24) are arranged in front of the adjacent wheels (10) or tracks as viewed in the direction of travel.

Description

technical field [0001] The invention relates to a road milling machine for processing road surfaces or ground and to a method for steering wheels or tracks of a road milling machine. Background technique [0002] Such a road milling machine is known, for example, from EP0836659. [0003] Good maneuverability of the road milling machine is essential for such road construction machines, especially small milling machines. For example, such road milling machines not only need to be suitable for straight-ahead and normal turning procedures, but also need to be able to navigate tight curves, for example, when needing to bypass traffic islands or manhole covers. [0004] In known small milling machines, therefore, the milling drum ends almost flush with one outer side of the machine frame, the so-called zero-clearance side. Thanks to this arrangement, it is possible to mill along obstacles very closely. It is also known to pivot the rear wheel on the zero-clearance side inwards ...
