Definitions

  • the invention relates to an actuator for an actuator according to the preamble of claim 1.
  • a known actuator for a throttle valve in the intake manifold of an internal combustion engine ( DE 196 12 869 A1 ) arranged between the engine output shaft and the actuating shaft transmission gear is a two-stage spur gear with an intermediate gear which meshes with a first gear portion with a seated on the engine output shaft motor pinion and a second gear portion with a fixedly arranged on the control shaft drive gear.
  • Drive gear and control shaft are rotatably mounted in a the actuator and the transmission gear receiving actuator housing.
  • a reset device ensures that in case of failure of the servomotor, the throttle valve is returned to a basic position in which only an emergency operation of the internal combustion engine is possible.
  • the restoring device has a concentric the adjusting shaft enclosing, designed as a cylindrical coil spring torsion spring and a rotatably received on the actuating shaft stop piece.
  • the torsion spring engages its one spring end on the drive gear and with its other spring end to the stop piece and is supported axially between the drive gear and stopper piece, which in turn is supported axially on the recorded in the actuator housing pivot bearing for the control shaft.
  • the torsion spring generates via its spring ends a torque on the drive gear and on the stop piece, which in turn cooperates via a stop arranged on it with a counter-stop arranged on the intermediate wheel. This return torque increases with increasing twisting of the throttle from its home position. In the event of failure of the servomotor, this restoring torque will return the throttle to its home position.
  • the transmission gear between the engine output shaft and control shaft is designed as a worm gear with worm and circular-toothed rack.
  • the worm is rotatably mounted on the motor output shaft, and the rack is slidably guided in the actuator housing along a circular arc.
  • On the actuating shaft a Mit promisingarm is fixed, which rests with its arm end on the front side of the rack.
  • a seated on the actuating shaft coil spring puts the driving arm frictionally against the toothed segment, so that the Mitiliaarm pivoted when moving the rack and thereby the actuating shaft is rotated with actuator.
  • a device for adjusting a rotatably mounted in the intake manifold of an internal combustion engine throttle is mounted therein, and a rotatably connected to the shaft of the throttle actuator, which is biased in the closing direction of the throttle by a first return spring and in the opening direction of the throttle entrained by the actuator continues a second, the actuator in the closing direction of the throttle biasing, return spring and finally the actuator in the opening direction of the throttle to a defined emergency position biasing third return spring.
  • a coupling member is provided between the actuator and the second return spring, which is biased by the second return spring in the closing direction of the throttle against a housing fixed emergency stop and the emergency stop by the actuator of the actuator in the opening direction of the throttle is entrained.
  • the present in the form of three return springs three energy storage device this device serve to convert the throttle in case of failure of the electric motor actuator in an emergency position.
  • the actuator according to the invention with the features of claim 1 has the advantage that between a motor output shaft and a first energy storage, a reduction gear is arranged and the first energy storage is coupled to a transmission output of the reduction gear.
  • a reduction gear is arranged and the first energy storage is coupled to a transmission output of the reduction gear.
  • the reduction gear arranged between the engine output shaft and the first energy store is preferably designed as a crown gear with a spur gear fixedly arranged on the engine output shaft and a crown wheel meshing with the latter, the wheel axis of the crown wheel being perpendicular to the engine gear.
  • Output shaft is aligned.
  • the on the transmission output the Kronengetriebes retroactive energy storage is designed as a return spring, which fixed locally with its one end of the spring on the crown wheel and with its other spring end.
  • the crown gear has - as a spur gear - hardly loss of efficiency and allows a tensioning of the return spring over several revolutions of the motor output shaft, as they are also required for adjusting the actuator.
  • the in Fig. 1 and 2 illustrated actuator for an actuator 10 ( Fig. 2 ) comprises an electric servomotor 11 with a motor output shaft 12, an actuating shaft 13, a transmission gear 14 arranged between the motor output shaft 12 and the actuating shaft 13 and a return device 15 for returning the actuator 10 to a basic position in case of failure or failure of the servomotor 11.
  • Das Actuator 10 may have a throttle in the intake manifold of an internal combustion engine, an air damper in an air conditioner or other pivotal element to control a duct cross section.
  • the actuator 10 is in Fig. 2 partially indicated.
  • the servo motor 11 and the transmission gear 14 are received in a cup-shaped actuator housing 16.
  • the control shaft 13 is rotatably mounted in the actuator housing 16.
  • the transmission gear 14 is formed as a worm gear, which has a seated on the motor output shaft 12 worm 17 and a worm wheel 18. The latter is rotatably mounted on the control shaft 13. Since the actuator 10 executes only a limited pivoting movement, the worm wheel 18 is formed as a wheel segment, wherein the wheel toothing extends over a circular arc of less than 180 °.
  • the return device 15 has an effective on the input side of the transmission gear 14, a first energy storage performing first return spring 21 and on the output side of the transmission gear 14 effective, a second energy storage performing second return spring 22.
  • the second return spring 22 is formed as a torsion spring, preferably as a cylindrical coil spring. It is dimensioned so that it is able to overcome the useful torque which can be removed on the control shaft 13.
  • the first return spring 21, however, is designed so that it is able to overcome the engine cogging torque.
  • the first return spring 21 is connected via a reduction gear 23 with the motor output shaft 12 in operative engagement.
  • the reduction gear 23 is preferably a crown gear with a fixedly arranged on the motor output shaft 12 spur gear 24 and one in the actuator housing 16 rotatably mounted crown gear 25 which is in meshing engagement with the spur gear 24 is formed.
  • the first return spring 21 is formed in the embodiment as a spiral spring 26 which is fixed with its one spring end 261 on the crown gear 25 and with its other spring end on the actuator housing 16.
  • the coil spring 26 is preferably located at the bottom of the crown gear 25 and protrudes with her in Fig. 1 not visible, fixed to the actuator housing 16 spring end through an arcuate slot at the bottom of the crown wheel 25 therethrough.
  • both return springs 21, 22 as spiral or cylindrical coil springs.
  • Fig. 1 exemplified the actuator is shown in a position in which the actuator 10 assumes its basic position.
  • the servomotor 11 is de-energized. If the motor is turned on with such a direction of rotation that the motor output shaft 12 rotates clockwise, the worm wheel 18 is pivoted in the direction of the arrow 19 via the rotating worm 17. At the same time the crown gear 25 is rotated over the rotating spur gear 24 so that the bias of the coil spring 26 increases.
  • the control shaft 13 is rotated, which in turn pivots the actuator 10 in a position in which it releases a flow cross-section to be controlled more or less far.
  • the cylindrical coil spring 20 is tensioned.
