  • Patent number: 9783938
    Abstract: A self-propelled construction machine, in particular a road milling machine, is described. It has a main drive for driving a rotating working means in a working operation and an auxiliary drive for driving the working means in a maintenance operation and a gear transmission on the working means. Lubricant oil is applied to the gear transmission via a lubricant oil circuit and a lubricant oil pump in the lubricant oil circuit, the lubricant oil pump being in drive connection to the gear transmission. An auxiliary pump is provided, which is optionally switchable into the lubricant oil circuit, so that, with reversal of the pump principle, the lubricant oil pump is operated as a hydraulic motor, wherein the drive connection of the lubricant oil pump and the gear transmission is also reversed to drive the gear transmission.

  • Patent number: 9764690
    Abstract: The present invention relates to a self-propelled ground milling machine, comprising a drive engine arranged in an engine compartment and an engine compartment enclosure which covers the engine compartment at least partly to the sides and to the top. A part of the engine compartment enclosure is a cover which is adjustable between a covering position and a maintenance position. At the same time, a maintenance platform is provided which is movable between a stowage position and a maintenance position. When the maintenance platform is in the maintenance position, an operator standing on the floor surface of the maintenance platform can carry out maintenance work in the engine compartment of the self-propelled ground milling machine. The self-propelled ground milling machine preferably is a road milling machine, more particularly a large milling machine, a surface miner, a stabilizer or a recycler.

  • Patent number: 9638112
    Abstract: 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.
