The present invention relates to a ground milling machine with two cooling ducts, which allow a mutually separated guidance of cooling air. The present invention further relates to such a cooling system and a method for cooling a ground milling machine.

Ground milling machine having a cooling system, cooling system, and method for cooling a ground milling machine

The present invention relates to a device in a self-propelled construction machine with a first driving unit, which provides for a first speed of rotation (n). By means of a planetary gear the first speed of rotation (n) is translated into a different speed of rotation (n) at which a working device of the construction machine, in particular a milling rotor for processing ground surfaces, can be operated.

Driving device in a self-propelled construction machine and method for setting a speed ratio in such a driving device

The present invention relates to a method and device for controlling a vehicle, more particularly, the power train of a compacting machine for earth moving operations, comprising a hydraulic travel pump and a hydraulic travel motor. Control is effected according to a specified control profile when a specified driving operation is to be carried out in that an adjustment of the travel pump is carried out which is independent of the rotational speed of the internal combustion engine. This makes it possible to retain, on the one hand, the rotational speed of the internal combustion engine in the case of abrupt stops of movement or changes in the direction of movement and, on the other hand, to adapt the rotational speed of the engine in the case of somewhat longer uninterrupted pauses between two changes in the traveling behavior, wherein comparatively large fluctuations in the rotational speed are avoided.

Method of controlling a power train of a vehicle and device for carrying out said method

The invention relates to a construction vehicle for preparation of a road surface, more particularly a road milling machine or a ground stabilizer, comprising a rotatably driven milling cutter, more particularly a milling rotor or a milling drum, and a drive unit for a milling tool, comprising a drive motor and a gear unit interposed between the drive motor and the milling cutter, wherein the gear unit is in the form of a cogwheel gearbox and comprises at least two gear pairings having different gear ratios, wherein the gear pairings can be selectively engaged to form part of the drive connection or disengaged therefrom.

The present invention relates to an interchangeable holder system comprising a basic module and an interchangeable holder for the accommodation of a cutting tool, which interchangeable holder is capable of being attached to the basic module, for the purpose of preparing ground surfaces, and to a construction machine, more particularly a stabilizer, a recycler, or a cold milling machine, comprising a milling device comprising such an interchangeable holder system.
