Definitions

  • the invention relates to a flap setting unit, in particular for internal combustion engines, having a flap mounted on a flap shaft, wherein the flap shaft is rotatably mounted in a flap nozzle, with a valve shaft coupled via a gear, arranged in the valve body actuator for adjusting the flap shaft, with a sensor unit for detecting a parking position of the valve shaft, with a cover to be fastened to the valve neck and with an electrical coupling element arranged on the cover.
  • Valve position units are used, for example, as flap valve actuating units in the exhaust gas recirculation line or as throttle position units in the intake line of the internal combustion engine.
  • a flap setting unit is known for example from DE-A1-195 25 510.
  • this flap setting unit of the servomotor and a servo motor with the Ktappenwelle and the flap mounted thereon connecting gear transmission are arranged in Drosseistutzen.
  • the adjusting wheel located on the valve shaft has wiper elements which interact with a potentiometer.
  • the potentiometer and electrical lines, an electrical coupling element and a motor plug-in contact with the motor connecting the motor coupling contact are arranged on the cover.
  • the arrangement of the electric motor coupling is structurally complex and moreover pollution and vibration prone, which can lead to an interruption of the electrical contact.
  • the invention is therefore based on the object to provide a flap setting unit which avoids the disadvantages mentioned above.
  • This object is achieved in that a cover-side bearing for a motor shaft of the servomotor and functional parts of the servomotor are arranged on the lid such that the servomotor is completed by placing the lid on the valve body.
  • the flap setting unit according to the invention is to produce in a particularly simple and cost-effective manner.
  • the engine is assembled by simply placing the lid.
  • Another advantage of this arrangement is that the delivery of engine power via the transmission now takes place between the two bearings, whereby the force is introduced into the motor shaft much cheaper.
  • FIG. 1 shows an exploded view of a flap setting unit 1 according to the invention, which is designed as a throttle flap setting unit.
  • the throttle valve adjusting unit 1 has a throttle body 2, in which a throttle shaft 3 is rotatably mounted. On this throttle shaft 3, a throttle valve 5 is fixed by means of screws 4.
  • the throttle actuator unit 1 on a servomotor 6, which is arranged in the throttle body 2.
  • the servomotor 6 is in the present case via a gear transmission 7 connected to the throttle shaft 3.
  • the gear transmission 7 consists of a arranged on a motor shaft 8 pinion 9, a gear 10 and arranged on the throttle shaft 3 adjusting wheel 11.
  • a sensor unit 12 for detecting the control position of the throttle shaft 3 consists in the present embodiment of potentiometer paths 13, which interact in known manner with wiper elements 14 shown in FIG.
  • the potentiometer tracks 13 are arranged in a cover 15 which is plugged onto the throttle body 2.
  • the electrical coupling element 16 is further connected via electrical lines directly to the functional parts of the electric motor, which are arranged in the lid 15 and has an output for power supply and on-board Elekronik on.
  • the cover 15 further has centering elements 17, which allow a precise fit of the lid 15 on the throttle body 2.
  • snap-on elements 18 are provided on the lid 15 and the throttle body in a known manner, by which the lid 15 is fixed.
  • An intervention safeguard 25 acts as a lock to mark unauthorized opening.
  • FIG. 2 shows the lid 15 and the servo motor 6 and the gear transmission 7 of the throttle valve adjusting unit 1 according to the invention in section.
  • the servo motor shown in the embodiment is a DC motor with a pole ring 19, an armature 20 and a collector 21, which communicates with brush elements 22 in connection.
  • the cover 15 has a bearing 23 for the cover-side mounting of the motor shaft 8 and the brush elements 22, through which the servomotor is energized on.
  • the gear transmission is composed in a known manner from arranged on the motor shaft 8 pinion 9, the gear 10 and the adjusting 11 together.
  • the sensor unit 12 in the present case of wiper elements 14, which cooperate in a known manner with potentiometer 13. It should be clear that, of course, other sensor units, such as non-contact sensor units that act capacitively, magnetoresistive or acting on the Hall principle in the present throttle actuator unit can be used.
  • the assembly of the throttle valve adjusting unit according to the invention can now proceed as described below.
  • the potentiometer tracks 13 are inserted into the cover. These can be applied directly to the lid or used as shown by means of an intermediate element. However, the potentiometer tracks 13 with the intermediate element can also be inserted into the cover, wherein guide elements provide a precise fit arrangement in the lid. By provided on the lid spring elements, the intermediate element is brought under bias and it is automatically created an electrical contact with the coupling element 16. Also, a non-illustrated circumferential sealing ring can be provided on the lid 15. Then, the lid-side bearing 23 is inserted into the lid 15.
  • the brush elements 22 are fixed in the lid 15 and the motor shaft 8 with the collector 21, with which the Bürstenelmente 22 are to be engaged, inserted into the bearing 23, wherein also arranged with the pinion 9 in engagement gear 10 in the lid 15 becomes.
  • the lid 15 and the throttle body 2 can be joined together, wherein the snap connection elements 18 and the engagement fuse 25 engage and lock the throttle actuator unit 1.
