Abstract
The invention relates to a ground milling machine, comprising: a machine frame supported by front and rear travel units and at least partially height-adjustable; a milling drum housing arranged on the machine frame, comprising a milling drum that is rotatable about a horizontal axis of rotation perpendicular to the milling direction; a retaining device arranged in front of the milling drum housing in the milling direction with an adjustment device that enables the height adjustment of the retaining device in relation to the milling drum housing and the machine frame; and a ground contact device arranged in front of the milling drum housing in the milling direction with a contact runner and a mounting lever. The contact runner is adjustable in relation to the retaining device within a height-adjustment range and is mounted on the retaining device by way of the mounting lever. The contact runner comprises a first joint via which it is connected to the mounting lever in a pivotable fashion, the mounting lever being connected to the retaining device via a second joint and positioned between the contact runner and the retaining device in such a manner that, when the height of the retaining device is adjusted in relation to the contact runner, the mounting lever reaches or traverses an apex of the curve of movement of the mounting lever about the first or second joint, the apex delimiting the adjustment path of the mounting lever in the horizontal direction over the entire height-adjustment range, in particular in such a manner that the horizontal distance between the first and the second joint increases before subsequently decreasing. Finally, a distance measuring device is provided, with which the vertical distance or a correlating value between the machine frame and/or the milling drum housing and the contact runner can be measured.
