Definitions

  • the invention relates to a throttle valve device according to the preamble of patent claim 1.
  • Such a device is published with DE-C1-31 46 652 and has an electric motor drive which always allows a correction of the throttle valve position in the respective throttle valve position set by the engine operator.
  • the electric motor drive takes place via a pivotably mounted electric motor, which is arranged between the arbitrarily actuable mechanical actuation and the throttle valve shaft, a gear being arranged between the electric motor and throttle valve shaft.
  • This device has the disadvantage of movable electrical connection lines for the electric motor and it lacks a potentiometer as a position transmitter for the electric motor for a position control.
  • the arrangement of a potentiometer in this device encounters design difficulties.
  • the object of the invention is to design a specified device in such a way that static electrical connecting lines and the arrangement of a potentiometer as a position transmitter for the electric motor or the transmission are possible with little design effort.
  • the actuating lever 13 is connected to an accelerator pedal, not shown, and can be adjusted in accordance with an engine operator.
  • the toothed segment lever 14 bears under the force of an accelerator return spring, not shown, against an idling stop formed by an adjusting screw 21.
  • the segment lever 18 can be pivoted to the electric motor 17 by predetermined control signals.
  • the position of the segment lever 18 is detected by a potentiometer 22 connected to the segment lever 18.
  • Fig. 2 shows the segment lever 18, the toggle lever 10 with the guide pin 15 and the pivot lever 9 and the toothed segment lever 14, the guide pin 15 here engaging in a slide track 16 which causes the guide pin 15 to be guided, i.e. is designed as a slot.
  • the slide track 16 is designed according to FIG. 1 with a continuously changing distance to the pivot point of the segment lever 18 over the entire swivel range.
  • the guide pin 15 is pressed downward by the slide 16 so that the toggle lever 10 and the toothed segment 11 are pivoted and the angle between the toothed segment 14 or actuating lever 13 and the pivoting lever 9 or the throttle valve 5 is increased becomes.
  • the potentiometers 6, 22 and the electric motor 17 are connected to an electronic control unit via electrical lines (not shown).
  • the actuating lever 13 is not actuated, so that the toothed segment lever 14 bears against the adjusting screw 21.
  • the control device is supplied with operating values for engine load, speed, temperature, etc. and is processed in the control device according to predetermined programs in connection with the potentiometer signals to control signals for the electric motor 17.
  • segment lever 18 When starting the cold internal combustion engine, the segment lever 18 is pivoted to the left by the electric motor 17 until one for starting Suitable throttle opening indicated by the potentiometer 6 on the throttle valve shaft 3 is reached.
  • segment lever 18 When the internal combustion engine is started, the segment lever 18 is reset with increasing engine temperature, so that speed control / regulation takes place.
  • slide track 16 which has swivel sections for idling, warming up, cold starting and emergency running, which are set by the control unit or the electric motor 17, i.e. it goes without saying that the slide track 16 can have any configuration.
  • the device has static electrical lines. A position control of the segment lever 18 is possible by the arrangement of the second potentiometer 21.
  • the device can be created with simple design effort and forms a compact design.
