Embodiment Construction

[0041] Such as figure 1 The plant or construction machine 1 shown in FIG. 1 includes a frame 3 and a drive 6 . The drive device 6 serves to drive the movement device 2 and the working device 4 , which in this example is a milling device. In the present embodiment the movement device 2 is formed by wheels. The milling device 4 can be decoupled from the drive device 6 by means of a coupling device (not shown) and can be brought into a raised position (not shown) by means of a lifting device 5 on the frame 3 .

[0042] The lowered position shown here corresponds to the working position or working stroke for milling the ground surface 13 shown. As shown in the figure, the working device 4 rotates in the opposite direction to the machine 1 or the wheel 2 during the working stroke. In the raised or maneuvered position (not shown), the work implement 4 is no longer engaged with the ground surface 13 to be milled. In this position, the device moves "backwards" to the start of a ne...

Abstract

An apparatus for processing ground surfaces comprises a moving device, a working device, especially a milling device for milling the ground surface, and a drive device for driving the moving device and the working device, wherein the working device is movable between a working position, in which it is in operative engagement with the ground surface, and a maneuvering position, in which it is not in operative engagement with the ground surface, wherein a sensor device is provided which detects the maneuvering position and / or at least one working parameter of the working device, namely its power consumption, working speed, rotational speed or its inclination, and / or at least one load parameter of the moving device, and a control device which reduces the frictional connection between the drive device and the working device and / or the drive power transmitted by the drive device to the working device in the maneuvering position and / or in case of the detection of a deviation of the at least one detected working parameter or load parameter from a set parameter value.

Description

technical field [0001] The invention relates to an apparatus for treating earth surfaces. Background technique [0002] Such a motorized construction machine for treating surfaces is known from EP1408158B1. [0003] The road milling machine described therein comprises a frame with a drive motor for driving the movement device and for driving the working device. The motion means may include wheels or guide assemblies connected to the frame by lifting columns. [0004] As a roller drive, the drive is in particular intended to drive a milling drum for milling ground, preferably in counter-rotating operation. The milling drum can be decoupled from the drive system via a coupling. In the direction of travel, a height-adjustable scraper is arranged behind the milling drum, wherein the scraper slides over the ground surface already milled by the milling drum or the ground surface to be milled by the milling drum. During the milling operation, the bottom edge of the scraper is a...
