Abstract
A working machine has a drive engine, a transmission for the main drive and at least one power take-off. The power of the drive engine is branched in a first section to the main drive and in a second section to the power take-offs. A measuring device measures the power-limiting variable acting on an output drive. Measuring devices are provided on the working machine for determining the variable having a power-limiting effect on the respective power take-offs and on the transmission, such as for example a torque, a hydraulic pressure or an adjusting lever deflection. These are supplied as signals to an evaluating and control device which, based upon these input signals, generates a control signal for a power regulator which regulates the output power of the drive engine.
Claims33
A working machine having a main drive;
- a plurality of power take-offs for driving a plurality of implements;
- a drive engine whose drive power selectively is divided to the main drive and the power take-offs;
- measuring devices provided in the power take-offs and in the main drive for determining a power-limiting variable and delivering a signal correlative thereto;
- an evaluating and control device for receiving and processing the signals, and generating a control signal as a function of the signals;
- and a regulator for receiving the control signal and regulating the output power of the drive engine so that none of the power take-offs is overloaded.
A working machine having implements, an evaluating and control device for generating a control signal, a power regulator, a fuel injection pump, a drive engine whose drive power is branched to a main drive and at least one power take-off for driving the implements, and wherein the drive power of the drive engine directly controls the fuel injection pump via the power regulator which, in case of altered power requirements, receives the control signal from the evaluating and control device for the fuel injection pump such that the drive engine is adapted to new power requirements.
