摘要： The invention relates to a mobile machine having a traction drive and working hydraulics. The drive unit has a radial piston pump which is driven by a drive set and supplies working hydraulics. The radial piston pump is arranged on the axis of the output drive shaft of the drive set, between the drive set and a gearbox which is connected thereto via the output drive shaft. The drive set, the radial piston pump and the gearbox in this case form a compact drive unit.

摘要： A control system for a variable pump and a process to control the variable pump with a circuit connected to a hydraulic motor by working lines, controlled by an electronic controller, having check valves in the circuit to allow oil flow from a charge pump going into the circuit and further consisting of high pressure relief valves to allow oil flow out of the working lines to limit maximum pressure. A temperature sensor is placed between the high pressure relief valves and the connected check valves. A signal is processed in an electronic control to control the displacement of a variable pump, depending on temperature measure of the fluid flowing across the high pressure relief valves.
