Definitions

  • the invention relates to an electrically controllable actuating device according to the preamble of claim 1.
  • Such adjusting devices are already known, in which the transmission of the position of the accelerator pedal to the throttle valve is carried out by an electronic closed-loop control system.
  • the position or movement of the accelerator pedal is detected by a pedal value transmitter and the throttle valve is adjusted as a function of engine parameters via an electronic controller and an actuator connected to it, for example an electric motor.
  • the object of the invention is to design an actuating device of the type mentioned at the outset in such a way that this disadvantage is avoided.
  • the advantage achieved by the invention is, in particular, that by using the pedal value sensor mechanically coupled to the accelerator pedal on the throttle valve shaft in the event of a fault, a vehicle equipped with this system can be operated completely normally even in critical traffic situations, and the operator is able to visit a repair workshop under your own steam.
  • the drawing shows an electrically controllable adjusting device 1 for adjusting a throttle valve 2 of a fuel mixture throttle device 3, consisting of an accelerator pedal (not shown in the drawing), which is attached to a pedal value transmitter 4 via a mechanical connection, for example a throttle cable or a linkage Actuating lever 5 is connected, and an electric motor 6, optionally controlled by the pedal value transmitter 4 via a control unit, which adjusts a reduction gear formed by a pinion 7 and a gear wheel 8.
  • the double-acting coupling element 10 provided with lugs 11, is axially displaceable on a throttle valve shaft 13 with the aid of a compression spring 12 and forms a non-positive connection with the throttle valve 2 by means of a wedge 14 thereon.
  • the pedal value transmitter 4 which is provided on one side with a setpoint potentiometer 15 and on the other side with recesses 16, is rotatably arranged on the throttle valve shaft 13 and is actuated by a return spring 17 which is supported on the actuating lever 5 or on the fuel mixture throttle device 3, brought into a closed position if necessary.
  • the throttle valve shaft 13 which is axially non-rotatably connected to the coupling element 10 via the wedge 14 ′, is actuated via the actuating device 1 by turning the pedal value transmitter 4 and by virtue of the fact that the coupling element 10 positively engages the clutch 9 against the compression spring 12 by electromagnetic force , moved with the help of the electric motor 6 and via the reduction gear comprising pinion 7 and gear 8 against the closing force of a return spring 18 within defined stops and thus opened or closed the throttle valve 2.
  • the current position of the throttle valve is fed to the control unit via an actual value potentiometer 19.
  • the electrical clutch 9 is switched off and the coupling element 10 is pressed with the lugs 11 by the force of the compression spring 12 against the pedal value transmitter 4 provided with the lugs 11 corresponding to the lugs 11.
  • These coupling devices 11, 16 are designed in such a way that they snap into place and thus have a non-positive connection only in a certain position can and thus a meaningful assignment of throttle valve position and pedal position sensor is guaranteed.
