摘要： The invention relates to a control arrangement for vehicles having a hydrostatic auxiliary drive for one or more axles, in particular for motor graders, having a drive engine, driven rear wheels coupled to the drive engine, further wheels which can be activated by associated hydraulic motors and can be operated by a hydraulic pump coupled to the drive engine and which has an adjustable feed volume, wherein each wheel is connected to a hydraulic motor without a clutch. The hydraulic pump and the hydraulic motors can be activated electrically and adjusted in a continuously variable fashion and the hydraulic pump is connected directly, without valves, to the hydraulic motors in parallel by hydraulic lines. The control device controls the respective displacement volume of the hydraulic motors only as a function of the rotational speed signals of the sensors.

摘要： The invention relates to a hydraulic control system for building machinery, particularly for controlling hydraulic consumers of an excavator. According to the invention, pump channels which ensure that the hydraulic consumers are supplied in parallel by means of a spool valve of the main control unit of the piece of building machinery are provided in addition to previously existing pump channels that ensure said hydraulic consumers are serially supplied with hydraulic fluid. The additional pump channels are arranged parallel to the previously existing ones.
