Definitions

  • the invention relates to a valve actuating unit, in particular for internal combustion engines, with a flap attached to a valve shaft, the valve shaft is rotatably mounted in a valve neck, with one with the valve shaft via a gear coupled servomotor arranged in the flap neck for adjusting the valve shaft, with a sensor unit for detecting a Position of the valve shaft, with one to be attached to the valve neck Cover and with an electrical coupling element arranged on the cover.
  • Flap actuators are used, for example, as flap valve actuators in the Exhaust gas recirculation line, or as throttle valve control units in the intake line the internal combustion engine used.
  • a flap actuator is for example known from DE-A1-195 25 510.
  • the damper actuator are the servomotor and the servomotor with the valve shaft and the one on it fixed gear connecting gearbox arranged in the throttle neck.
  • the adjusting wheel located on the valve shaft has grinder elements that interact with a potentiometer.
  • the potentiometer as well electrical lines, an electrical coupling element and the electrical Coupling element with the motor connecting motor plug contact are on Lid arranged.
  • the arrangement of the electrical motor coupling is constructive complex and also susceptible to contamination and vibration, resulting in a Interruption of the electrical contact can result.
  • the invention is therefore based on the object of a valve actuating unit to create, 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 on the cover are arranged that the servomotor by placing the cover on the valve neck is finished.
  • the flap actuator unit according to the invention is particularly simple and inexpensive Way to manufacture.
  • the fact that the cover-side bearing as well essential functional parts of the servomotor can be arranged on the cover the complete electrical motor coupling is eliminated.
  • the engine is simple Put the lid on assembled. Another advantage of this arrangement is that the delivery of the engine power via the gearbox now between the two bearing points takes place, which causes the force transmission into the motor shaft done much cheaper.
  • FIG. 1 shows a valve actuating unit 1 according to the invention, which is used as a throttle valve actuating unit is executed in an exploded view.
  • the throttle valve control unit 1 has a throttle valve connector 2, in which a throttle valve shaft 3 is rotatably mounted. On this throttle valve shaft 3 is by means of screws 4 a throttle valve 5 is attached.
  • the Throttle valve actuating unit 1 has a servomotor 6 which is in the throttle valve connector 2 is arranged.
  • the servomotor 6 is in the present case via a gear transmission 7 connected to the throttle valve shaft 3.
  • the gear transmission 7 consists of an arranged on a motor shaft 8 Pinion 9, a gear 10 and one arranged on the throttle valve shaft 3 Adjustment wheel 11.
  • a sensor unit 12 for detecting the position of the Throttle valve shaft 3 in the present exemplary embodiment consists of potentiometer tracks 13, which in a known manner with grinder elements shown in Figure 2 14 cooperate.
  • the potentiometer tracks 13 are in one Cover 15 arranged, which is attached to the throttle valve 2. Via electrical lines, not shown, which are arranged in the cover 15, is the potentiometer 12 with an electric arranged on the cover 15 Coupling element 16 connected.
  • the electrical coupling element 16 is furthermore via electrical cables directly to the functional parts of the electrical Connected motor, which are arranged in the cover 15 and has an output for power supply and onboard electronics.
  • the lid 15 has Furthermore, centering elements 17, which fit the cover with a precise fit Allow 15 on the throttle valve assembly 2. Next are on the lid 15 and on the throttle valve assembly in a known manner snap connection elements 18 provided by which the lid 15 is fixed. Tamper-evident device 25 acts as a lock to indicate unauthorized opening.
  • FIG. 2 shows the cover 15 and the servomotor 6 and the gear transmission 7 the throttle valve control unit 1 according to the invention in section.
  • the in the embodiment The servomotor shown is a DC motor with a pole ring 19, a Armature 20 and a collector 21, the brush elements 22 in connection stands.
  • the cover 15 In the preassembled state, the cover 15 has a bearing 23 for the cover-side Bearing of the motor shaft 8 and the brush elements 22 through which the Actuator is energized on.
  • the gear transmission is made in a known manner from that on the motor shaft 8 arranged pinion 9, the gear 10 and the adjusting wheel 11 together.
  • the sensor unit 12 consists of wiper elements 14, which cooperate with potentiometer tracks 13 in a known manner. It should be clear that of course other sensor units, such as non-contact sensor units that act capacitive, magnetoresistive or act on the Hall principle in the present throttle valve actuating unit can be.
  • the assembly of the throttle valve actuating unit according to the invention can now be carried out as follows as described.
  • the potentiometer tracks 13 with the intermediate element can also be inserted into the lid be, with guide elements a precisely fitting arrangement in the lid provide.
  • the intermediate element is provided by spring elements provided on the cover brought under tension and there is an electrical contact automatically to the coupling element 16 created.
