摘要： The self-propelled construction machine according to the invention, in particular road-milling machine, recycler, stabiliser or surface miner, comprises a machine frame 2, which is supported by a chassis 1, which has wheels or tracks 1A, 1B. A milling drum 4 is arranged on the machine frame. The wheels or tracks 1A, 1B and the milling drum 4 are driven by a drive unit 8. Furthermore, the construction machine comprises a control unit 19 for controlling the drive unit 8 and a signal-receiving unit 18 for detecting at least one measurement variable M(t) which is characteristic of an operating state of the milling drum 4. The construction machine is characterised in that the rotational speed of the milling drum 4 is adapted, on the basis of at least one measurement variable M(t) which is characteristic of a critical operating state of the milling drum, to the operating conditions of the construction machine in such a way that the milling drum is operated in a non-critical operating state. The adaptive open-loop control of the milling drum rotational speed allows the construction machine to be operated at an optimum operating point with respect to the milling drum rotational speed.

摘要： The invention relates to a self-propelled construction machine, comprising a machine frame supported by a chassis having wheels or crawler tracks. The basic principle of the invention involves determining a variable Δ which is characteristic of the milling profile on the basis of a functional relationship between the variable which is characteristic of the milling profile and the advance speed v and/or milling drum rotational speed n. The variable Δ which is characteristic of the milling profile is a correction variable for adjusting the height of the milling drum with respect to the surface of the ground.

摘要： An earth working machine encompasses a machine body having a machine frame and a drive configuration rotationally drivable relative to the machine frame around a drive axis (A). It further encompasses a working apparatus (32) for earth working to which the drive configuration is releasably connected in drive torque-transferring fashion for rotation together, the drive configuration projecting from an axial end axially into the working apparatus (32) and the working apparatus (32) being retained on the drive configuration, against axial displacement relative to the drive configuration, by an accessible central bolt arrangement having a bolt axis collinear with the drive axis (A). Provision is made according to the present invention that the earth working machine encompasses a bolting moment bracing arrangement (82) which is connected or connectable in bolting moment-transferring fashion to a bolt component, helically movable relative to the drive configuration, of the bolt arrangement, and which comprises a bracing region (82e, 82gf) that is embodied for bolting moment-bracing abutment in a bracing bolting direction against a counterpart bracing region (84b, 84c), the drive configuration being embodied to be driven to rotate, in a rotation direction codirectional with the bracing bolting direction, while the bracing region (82e, 82f) is in abutment against the counterpart bracing region (84b, 84c).

摘要： A civil engineering machine has a machine control unit configured to determine data which defines the position and/or orientation of a reference point on the civil engineering machine in relation to a reference system independent of the position and orientation of the civil engineering machine. A geometrical shape to be produced on the ground is preset in either a machine control unit or a field rover control unit. The field rover is used to determine a position of at least one identifiable point of the preset geometrical shape in the independent reference system. Curve data defining a desired curve in the independent reference system, corresponding to the preset shape, is determined at least partially on the basis of the position of the at least one identifiable point of the preset geometrical shape in the independent reference system.
