Embodiment Construction

[0062] Identical or functionally identical components may be designated by the same reference numerals in the figures. Each component that is repeated in the figures is not necessarily individually labeled in each figure.

[0063] figure 1 First, the flow of the method 1 according to the invention is shown. Figures 2 to 13 The individual method steps are shown on a specific embodiment of the floor milling machine 2 according to the invention. Figure 16 The basic structure and preferred refinements of a control unit and a sensor system suitable for carrying out the method according to the invention are shown.

[0064] An essential element of the method according to the invention for controlling the height adjustment of the height-adjustable running gear of a self-propelled floor milling machine is that, in a first step 3A, the working direction of the floor milling machine is determined and monitored The inclination of the upper frame and / or the change in the inclination o...

Abstract

The invention relates to a method for controlling the height adjustment of a height-adjustable chassis of a self-propelled ground milling machine, and to a ground milling machine, in particular a road milling machine, comprising: a base; a frame; at least one of the driving devices is connected with the rack through a height-adjustable lifting device; the milling roller is supported on the rack; the rack inclination sensor is arranged on the rack and used for detecting the inclination of the rack in the operation direction; the ground contact element inclination sensor is arranged on a ground contact element which can be adjusted relative to the machine frame and is used for detecting the inclination of the ground contact element in the working direction; and a control unit that controls the at least one height-adjustable rear lifting device in accordance with inclination data determined by the rack inclination sensor and the ground contact element inclination sensor.

Description

technical field [0001] The invention relates to a method for controlling the height adjustment of a self-propelled ground milling machine, in particular a height-adjustable running gear of a road milling machine, and a ground milling machine. Background technique [0002] Ground milling machines of this type are commonly used in road construction during road refurbishment and here in particular for removing road surfaces at the desired milling depth. For this purpose, it is known to lower a working device in the form of a milling roller which is rotatable about horizontal and transverse to the working direction into the foundation by adjusting the height of the frame relative to the foundation until the desired milling depth is reached. . For this purpose, the milling rollers can be supported on the frame of the floor milling machine, in particular inside the milling roller box, and can be adjusted vertically together with the frame by means of suitable lifting devices. Su...
