Definitions

  • the invention relates to an actuating device for a throttle valve of an internal combustion engine according to the preamble of patent claim 1.
  • Such an actuator is already disclosed in DE-OS 29 42 296 in a carburetor for controlling the position of the throttle valve for the purpose of controlling the engine idling speed, regardless of whether this engine idling speed by the operator, for. B. a motor vehicle is exceeded or not.
  • the servomotor used in this actuating device is a linear motor, which only engages in the opening direction of the throttle valve against a throttle lever (second plate) connected to the throttle valve, namely against the action of force clamped between an actuating lever (first plate) and the throttle lever Coupling spring.
  • an actuator in which an electric motor acts via a gear against the closing force of a return spring on the throttle valve and adjusts it in accordance with control signals.
  • a Bowden cable which acts on a throttle lever via an additional spring and is connected to the accelerator pedal, tensions this additional spring in the event of an accelerating gas actuation. With this device, too, an active adjustment of the throttle valve by the electric motor is only possible in the area that has been released by the accelerator pedal.
  • the object of the invention is to design an actuating device mentioned in the introduction in such a way that an active adjustment of the throttle valve is independent of the accelerator pedal position is achievable, but security aspects must also be taken into account.
  • an actuating device 1 consisting of an actuating lever 2 connected to the accelerator pedal of a motor vehicle, which in the idle position under the force of a return spring 3 bears against an adjustable idling stop 4, which can correspond to an increased idling speed in relation to the throttle valve position, a throttle lever 6 fixedly connected to a throttle valve shaft 5, a throttle valve 7 arranged on the throttle valve shaft 5 and arranged in an air intake duct section of an internal combustion engine (not shown).
  • the throttle valve shaft 5 on the other hand, carries a disk 8 of an electromagnetic clutch 9, the other disk 10 of which is arranged on a gear lever 11, to which an electric motor 12 engages with a pinion 13.
  • the electric motor 12 receives electrical control signals, not shown Control unit and adjusts the throttle valve 7 in accordance with the accelerator pedal position and a control program stored in the control unit, which functions depending on the operating parameters of the internal combustion engine.
  • the position of the actuating lever 2 is determined by a setpoint potentiometer 14 and that of the gear lever 11 by an actual value potentiometer 15 and fed to the control unit.
  • a leg spring 16 is arranged as a coupling spring between the actuating lever 2 and the throttle lever 6, which clamps the two levers 2 and 6 together under tension in a predetermined position.
  • This position of the two levers 2 and 6 is only changed when one of the levers 2 and 6 overcomes the spring torque caused by the leg spring 16, which is the case when the higher-level adjustment of the throttle valve 7 by the electric motor 12 from the adjustment of the Actuating lever 2 deviates, d. H.
  • the spring torque can be overcome in both directions, as a result of which a throttle valve position above or below the one specified by the actuating lever 2 can be set.
  • FIG. 2 and 3 show the arrangement of the leg spring 16 in a spring cup 17 as a detail, the spring cup 17 being freely rotatably mounted on the throttle valve shaft 5 and receiving the leg spring 16 with a leg 18 on the outer edge.
  • the leg spring 16 wound in the pot 17 presses the two levers 2 and 6 projecting through a recess 19 through the pot 17 with their free leg 20 under tension against a recess wall 21. If the predetermined position of the two levers 2 and 6 is changed to one another, then one lever always holds the spring cup 17 and the other lever the free leg 21 of the leg spring 16 fixed (Fig. 3).
  • the spring torque can thus also be overcome in both directions. Compared to the embodiment according to FIG.
  • this embodiment results in a more precise position of the levers 2 and 6 with respect to one another due to their abutment on the machined wall 21 and enables a more precise adjustment of the spring torque.
  • the spring cup 17 offers the possibility of arranging two springs (redundant system) and protection against contamination.
  • the actuating device shown is particularly suitable for use in motor vehicle engines that have to comply with special exhaust gas laws and safety requirements.
  • the control unit After switching on the ignition, the control unit is activated and, after evaluating sensor signals via temperature, etc., provides control signals for the electric motor 12, as a result of which the throttle valve 7 assumes an opening position required for starting, the spring torque being overcome here and the position of the levers relative to one another .
  • the controlled electric motor 12 takes over the adjustment of the throttle valve 7 for engine warm-up. If the actuating lever 2 is adjusted from its idle position by accelerator pedal actuation, then the setpoint potentiometer value changes and the control unit outputs corresponding control signals to the electric motor 12 until the setpoint and actual value potentiometer values match.
  • the gear lever 11 follows the adjustment of the actuating lever 2, so that the position of the levers 2 and 6 does not change relative to one another. If the accelerator pedal is pressed quickly or the electric motor opens slowly according to the control program 12, the position of levers 2 and 6 to each other is changed as well as during start and warm up.
  • the new actuator also enables engine operation with speed control.
  • the magnetic coupling 9 separates the gearbox 11 from the throttle valve shaft 5, so that the levers 2 and 6 remain in their predetermined position or get into it by the spring torque.
  • the throttle valve 7 only follows the adjustments caused by the actuating lever 2, as in a previously conventional mechanical transmission system.
  • the throttle valve 7 is adjusted exclusively via the electric motor 12, with further signals for detecting a failure, e.g. B. from the braking system can be processed in the control unit.
  • the aforementioned setting of the idle stop for an increased speed offers the possibility of emergency operation with restricted function.
  • leg spring can also be replaced by two springs connected in parallel, which, just as with the return springs of the actuating lever, provides a redundant system.
  • the actuating lever can have one or two stops protruding into the movement path of the throttle lever 6, which, however, are not shown because of the conceivability, in which case the electric magnetic coupling 9 can be omitted.
