Definitions

  • the invention relates to a device for controlling a predetermined, constant holding speed of an internal combustion engine with an electronic speed control device.
  • the object of the invention is to provide a device with which the achievement of constant Preset speed of an engine to be maintained as a central drive unit for one or more switchable work machines for the operator is facilitated.
  • the invention solves this problem by an additional circuit with the features of Claim 1.
  • the additional circuit is automatically activated when the machine is switched on and this automatically sets a pre-settable, constant engine speed controlled. The operator does not have to do this every time the Run the engine manually. Incorrect settings of the working speed of the Drive machine are largely avoided. It is particularly advantageous that by arranging an additional circuit to be operated externally in the engine's own Electronics do not have to be intervened. It remains completely unchanged.
  • the additional circuit according to the invention is in particular when used for street cleaning vehicles of great advantage. These are with multiple work machines, so several power consumers, such as drive wheels, sweeping brushes, suction device and the like, equipped, the power transmission being hydraulic.
  • the drive motor drives a hydraulic pump in the form of a swivel pump, the pressure oil flow of which Service customers is distributed.
  • the constant speed of the drive machine is required because the suction device remains in operation even when the vehicle is stationary.
  • additional customers such as sweeping brushes and wheel drive
  • Torque of the drive motor via the engine electronics increases by the fuel supply is increased accordingly.
  • the additional circuit is automatically activated via an external switching contact. After this The additional circuit is reached when the preset speed of the drive motor is reached automatically switched off, since it is equipped with a device for comparison of target and actual values is.
  • the additional circuit 2 is activated by an external switching contact 1. It is provided with a setpoint memory 3 and, via the speed control device 5 assigned to the motor electronics 4, automatically controls a presettable and constant motor speed. For this purpose, the additional circuit activates the speed control device 5 of the engine electronics via a control signal S 1 . In addition, the control signal S 2 for the speed increase is entered until a motor speed signal S 0 proportional to the preset engine speed is detected at the input of the additional circuit. 6 is the drive motor and 7 the motor wiring harness. A setpoint / actual value comparison circuit 8 is located within the additional circuit.
