SELF-PROPELLED CONSTRUCTION MACHINE AND METHOD FOR PROCESSING FLOOR COVERINGS
A self-propelled construction machine (1) comprises a machine frame (4), at least three travelling devices (2), at least one hydraulic drive system (50) for driving at least two travelling devices, wherein the hydraulic drive system comprises at least one controllable hydraulic motor with variable displacement volume and at least one hydraulic pump, at least one working device (e.g. a milling drum), for working the ground pavement. A detection device(44, 60, 62) detects fluctuations in the longitudinal speed of the construction machine (1) during movement thereof, wherein a control unit altersthe displacement volume of the at least one controllable hydraulic motor as a function of the detected fluctuations so that the natural frequency of the hydraulic drive system is altered, wherein thecontrol unit adjusts the discharge volume of the pump as a function of the amount of adjustment of the displacement volume in such a fashion that the specified drive speed remains constant.
自推进式建筑机械(1)，包括机架(4)；至少三个行进装置(2)；用于驱动至少两个行进装置(2)的至少一个液压驱动系统(50)，液压驱动系统包括至少一个能够控制的液压马达，和至少一个液压泵，液压马达具有能够改变的排量容量；至少一个作业装置，具体是铣刨鼓(6)；其设置成实现以下特征：设置检测装置(44，60，62)，在建筑机械(1)的移动期间，其检测建筑机械(1)的纵向速度(v实际)的波动，其中控制单元(38)根据所检测到的波动改变至少一个可控液压马达的排量容量，以改变建筑机械的液压驱动系统的固有频率，控制单元(38)根据排量容量的调节量以使指定的驱动速度(v驱动)保持恒定的方式调节泵的排放容量。
