Problems solved by technology

As a result, the slewing gear used must be constructed to be very robust and resistant
This results in higher production costs, increased machine weight and, if the slewing process is automated, requires a more powerful slew drive

Embodiment Construction

[0035] Identical components are represented by the same reference numerals in the figures, but components that are repeated in multiple figures are not individually identified in each figure. Figure 1a and 1b A plan view of the construction machine 1 is shown, in which only the main components are shown: the frame, the running gear, the milling device and the device for load relief. Other components, such as drives, operating stations, etc., are omitted for the sake of clarity, which are Figure 1c shown in side view. figure 2 and 3 It is a perspective view of the area of ​​the rear running gear of the construction machine viewed obliquely from the front right. The main parts of the chassis are only represented by dashed lines so that they can be seen from other perspectives depending on the emphasis Figure 1a and 1b components shown in . FIGS. 4 a and 4 b also relate to sub-regions of the construction machine, in particular the region of the machine frame in which the ...

Abstract

The invention relates to a ground milling machine, which has: a frame; a milling device supported on the frame, the milling device has a milling roller box and a milling roller box arranged in the milling roller box; planing rollers; and a plurality of running gear supported on the frame. At least one running gear is supported on the frame by means of a slewing transmission, and can swing between a swing-out position protruding from the frame toward the side and a swing-in position swinging in toward the frame. The invention provides the possibility to realize a direct transmission of load-bearing forces between the machine frame and the running gear, so that the slewing drive is free from load-bearing forces. The invention also relates to a method for inclination and outward oscillating of the running gear of a ground milling machine.

Description

technical field [0001] The invention relates to a ground milling machine with a frame, a milling device supported on the frame and a plurality of running devices supported on the frame, the milling device comprising a milling roller box and the milling rollers arranged in the milling roller box, wherein at least one running gear is supported on the frame via a slewing gear, which can be swiveled in the laterally protruding outwards of the frame and into the frame swing between the in-swing positions. Background technique [0002] Ground milling machines of this type are known, for example, from DE 196 31 042 C2 and DE 10 2001 034662 A1, the disclosures of which are hereby incorporated by reference. The ground milling machine disclosed here has a frame on which a running gear having a total of four running gears is arranged. The running gear currently refers specifically to the wheel or the crawler, and it may also be a mixed form. In the ground milling machines known from...
