Abstract: An embodiment of a holding structure includes at least one receiving eye with a central receiving axis; at least two fixing points, with each fixing point having a fixing axis that runs parallel to the at least one receiving axis; a first wall and a second wall provided on opposite sides of the holding structure. In embodiments the first wall and the second wall are spaced apart in the direction of the at least one receiving axis; the at least one receiving eye extends from one of the two walls to the other wall; and the holding structure has at least one cavity that is provided between the first wall and the second wall.

Abstract: A method calculates an excavation volume that was excavated by a construction machine using a tool. A motion trajectory of the tool over time is determined using one or more of the following sensors: inertial measurement unit, angle sensors, and linear sensors. At least part of the motion trajectory is classified based on machine load data as an excavation trajectory during which excavation occurs. The excavation volume is calculated using the excavation trajectory and dimensions of the tool.

Abstract: There are disclosed a method and a lifting mechanism for actively damping in mobile working machines vibrations which may occur as a result of raised attachments during travel. The method or the lifting mechanism has a prediction or a predictor for estimating the future vibration. The prediction is preferably carried out with a recursive least squares algorithm. The mobile working machine may, for example, be a tractor.

Abstract: A dual mass flywheel protection system includes an engine coupled to a transmission using a dual mass flywheel defining a drive train. A gear determiner identifies a present operational gear. A filtered engine speed is available. A torque reduction module applies the present operational gear and filtered engine speed producing signals limiting an engine torque to reduce engine torque variations. A first torque limitation option limits engine torque when the drivetrain is coupled, dependent on an engine rpm, which is related to an actual gear selected. A second torque limitation option determines an engine torque reduction during an emergency braking maneuver while an anti-lock brake (ABS) system is active. An engine shut-off module produces an output signal shutting off the engine upon initiation of one of multiple engine shut-off module outputs, and is active when an engine torque limitation due to a low engine rpm is not present.

Abstract: The disclosure relates to a device of a vehicle, in particular a tractor, having a hydraulic activation unit for controlling the operation of a towed implement on the vehicle, comprising at least one position detection unit with at least one camera, position detection marks, and an evaluation unit and a data-transmitting connection to a control unit which is assigned to the hydraulic activation unit. Furthermore, a method is proposed, wherein by means of such a position detection unit the position of the towed implement can be determined, and the position can be adjusted according to requirements by suitable operation of the hydraulic activation unit.
