Definitions

  • the invention relates to a load adjustment device with a throttle valve arranged in an intake duct, the actuating shaft of which is driven by an actuating motor.
  • Load adjustment devices of the type mentioned have recently been installed frequently in place of mechanical load adjustment devices in which the accelerator pedal is connected to the throttle valve via a linkage or a cable pull.
  • the electrical transmission of the accelerator pedal movement to the throttle valve has a number of advantages over the mechanical one; in particular, the laying of electrical transmission lines is considerably less complex than the arrangement of a mechanical transmission device.
  • a mechanical transmission device is usually not completely dispensed with, but instead carries a so-called emergency actuation device with play, so that if the electrics fail after this play has been overcome, a mechanical throttle valve actuation is possible.
  • This additional mechanical emergency actuation device which is provided for reasons of redundancy, increases the Effort for such a load adjustment device is of course considerable.
  • the object of the invention is to design a load adjustment device of the type mentioned at the outset with as little effort as possible so that actuation is still possible even if important components fail.
  • a second intake duct with a further throttle valve is provided in parallel to the intake duct, the actuating shaft of the second throttle valve also being driven by an actuator and both throttle valves in the intake duct being arranged so as to be completely pivotable and in that the two actuating shafts are actuated by one Carrier connection having play are connected to one another.
  • a particularly advantageous embodiment of the invention is that the servomotors are designed as a stepper motor.
  • the arrangement of stepper motors has the advantage that there is no need for complex feedback potentiometers for the throttle valves and thus also for the complex laying of feedback lines. It is sufficient if a simple switch generates a signal when the throttle valve is closed, so that the zero position can be determined when the accelerator pedal is actuated.
  • Another advantage of the stepper motors is that they do not have a collector, so that the problem due to carbon brushes lifting off does not occur.
  • the load adjustment device is particularly compact if, according to another embodiment of the invention, the servomotors are arranged in mirror image to one another above or below the two intake ducts and are connected to the respective actuating shaft via a gear arranged laterally of the respective intake duct.
  • Another, very advantageous embodiment of the invention is that the play with the throttle valves aligned in the same way is approximately 90 degrees on both sides and the two slip clutches are designed such that they form a positive connection after a relative rotation of 90 degrees.
  • the play By setting the play to 90 degrees, a full actuation of the still intact throttle valve is possible without the frictional force of a slip clutch counteracting it.
  • the idle power of the load adjustment device can be regulated particularly sensitively if the load adjustment device has a control device for actuating only one servo motor for idle control and for synchronously actuating both throttle valves in load operation.
  • a failure of a throttle valve drive can be determined in a simple manner if both actuating shafts are assigned a safety contact for monitoring the rotary movement of the respective actuating shaft.
  • the load adjustment device is designed to be particularly simple in terms of construction if, according to another embodiment of the invention, the driver connection is formed by a sector-shaped projection of the one control shaft and a sector-shaped projection of the other control shaft arranged above it.
  • the slipping clutches are designed to be particularly simple if each slipping clutch has a pin guided radially through the respective adjusting shaft and two stop segments on the respective gearwheel to limit the maximum possible relative movement.
  • the interposition of a gearbox between the respective servomotor and the respective actuating shaft can be dispensed with if the servomotors are arranged directly on the actuating shafts of the throttle valves without the interposition of a gearbox.
  • the actuating shafts can run in alignment with one another so that the driver connection already explained can be used.
  • the actuating shafts run parallel to one another and that in order to form the driver connection, an actuating segment with a circular elongated hole is arranged on each actuating shaft in radial alignment, in which a coupling rod connecting the actuating segments engages.
  • the slip clutches are unnecessary.
  • the driver connection is very simple.
  • FIG. 1 shows a throttle valve connector 1, which has two parallel intake ducts 2, 3, each with a throttle valve 4, 5.
  • the two throttle valves 4, 5 are each arranged on a horizontally arranged actuating shaft 6, 7, both of which are in alignment with one another and are coupled to one another by a driver connection 8 having play.
  • Both actuating shafts 6, 7 are led out laterally from the throttle valve connector 1 and are each connected to a gear 11, 12 there by means of a slip clutch 9, 10.
  • Each gear 11, 12 consists of three intermeshing gear wheels 13, 14, 15, the gear wheel 15 on an output shaft 16 of a servomotor 17 designed as a stepping motor is rotatably arranged.
  • a second servomotor 18, also designed as a stepper motor, is arranged in mirror image of the first servomotor 17 on the upper side of the throttle valve connector 1 and drives the actuating shaft 7 in the same way via the gear 12.
  • each actuating shaft 6, 7 is assigned a safety contact 19, 20 which, when the actuating motor 17, 18 is energized but the actuating shaft 6, 7 is not rotating, controls a warning device 21, 22.
  • FIGS. 2 and 3 show the design of the driver connection 8 more precisely.
  • the mutually facing end faces of the two adjusting shafts 6, 7 each have a sector-shaped projection 23, 24. These projections each have an angle of 90 degrees, so that an angle of 90 degrees also remains between them, as shown in FIG. If the throttle valves 4, 5 move synchronously, the projections 23, 24 lie opposite one another. If, for example, the throttle valve 4 is at a standstill as a result of a defect, the right throttle valve 5 can pivot freely up to 90 degrees. In such a case, the normal operation of the right throttle valve 5 would in no way be hindered by the failed left throttle valve 4.
  • the right throttle valve 5 can be pivoted motor-wise through an angle of 90 degrees, the driver connection 8 taking the left throttle valve 4 with it after a pivoting angle of 90 degrees, so that it can be closed. This results in a relative movement in the slip clutch 9. After the load adjustment device has been repaired, this rotation in the slip clutch must of course be reset.
  • FIG. 4 and 5 illustrate the design of the slip clutch 12. It can be seen that the gear 13b is frictionally connected to the actuating shaft 7 via a plate spring 28. A pin 25 extends radially through the adjusting shaft 7, against which the gear 13b can turn with the stop segments 26, 27 shown in FIG. 5, so that the adjusting shaft 7 is carried in a form-fitting manner. If the gear 13b rotates counterclockwise and the actuating shaft 7 is sufficiently stiff, then there is a relative movement between the gear 13b and the actuating shaft 7 until the other side of the stop segments 26, 27 comes against the pin 25 and then the actuating shaft 7 carries along. Since both gearboxes 11, 12 have such a slip clutch 9, 10, if a gearbox 11, 12 is blocked via the other gearbox, the throttle valve, which is no longer functional, can be moved into the closed position due to a slipping clutch.
  • actuating shafts 6, 7 do not run in alignment, but parallel to one another.
  • Each control shaft 6, 7 is driven directly by a servomotor 17, 18.
  • the driver connection 8 is in turn designed so that both throttle valves 4, 5 can pivot independently of each other up to a maximum of about 90 degrees. In the event of a further pivoting, the other throttle valve 4 or 5 is taken along by the driver connection 8.
  • the structure of the driver connection 8 can be seen in FIG. 7. It has an actuating segment 29, 30 on each actuating shaft 6, 7, each with an arc-shaped elongated hole 31, 32.
  • the ends of a coupling rod 33 each engage in one of the elongated holes 31, 32.
  • closed position of the throttle valves 4 and 5 the coupling rod 33 each against a left boundary of the respective elongated hole 31, 32.
  • the right throttle valve 5 can no longer be actuated by the associated servomotor 18, then the right throttle valve 5 is carried along by the coupling rod 33 after pivoting the left throttle valve 4 by 90 degrees, so that it can be moved into the closed position.
