SELF-PROPELLED CONSTRUCTION MACHINE AND METHOD FOR CONTROLLING A SELF-PROPELLED CONSTRUCTION MACHINE

The invention relates to a self-propelled construction machine, in particular a road milling machine, stabiliser, recycler or surface miner, which has a machine frame supported by at least three running gears A, B, A, B, a drive device for driving at least two running gears, and a work roller arranged on the machine frame. The invention also relates to a method for controlling a construction machine of this kind. The drive device comprises adjustable hydraulic motors associated with the drivable running gears, which hydraulic motors have a displacement volume Vg that can be varied by an adjusting device A, A, A, A, and comprises at least one adjustable travel drive-hydraulic pump driven by at least one drive motor to supply the hydraulic motors with a variable total volume flow Q of hydraulic fluid. In addition, a controller is provided which is configured in such a way that a partial volume flow Q, Q, Q, Qis determined for each adjustable hydraulic motor from the total volume flow Q provided by the at least one travel drive-hydraulic pump , by means of which partial volume flow the particular hydraulic motor is to be operated, and when the speed n of an adjustable hydraulic motor increases as a result of slippage of the running gear associated with the adjustable hydraulic motor, the adjusting device of the adjustable hydraulic motor is controlled in such a way that a displacement volume Vg is set for the adjustable hydraulic motor, at which displacement volume the partial volume flow determined for the adjustable hydraulic motor is maintained. The self-propelled construction machine according to the invention is characterised in that a hydraulic flow divider is not required.
