Definitions

  • the invention relates to a load adjustment device with a power controlling an internal combustion engine, in particular as a throttle valve trained, arranged on an actuator shaft, the Actuating shaft by means of a reversible actuator between one Minimum load position and a full load position is pivotally driven, and with a single, as a return spring for biasing the control shaft in Minimum load direction and as an emergency running spring for pretensioning the actuating shaft against a run-flat stop torsion spring, the first end with the control shaft and its second end with an arm one between a minimum load stop and the emergency stop can be moved Support part is connected or connectable.
  • a load adjustment device with a power controlling an internal combustion engine, in particular as a throttle valve trained, arranged on an actuator shaft, the Actuating shaft by means of a reversible actuator between one Minimum load position and a full load position is pivotally driven, and with a single, as a return spring for biasing the control shaft in Minimum load direction and as an emergency running spring for pretensioning the actuating shaft against a
  • Load adjustment devices of the above type are generally under the Designation E-gas for power adjustment of the internal combustion engine from Motor vehicles known.
  • the load adjustment device is special as an emergency spring and as a return spring compact design and particularly light in weight.
  • a disadvantage of the known load adjustment device is that the ends of the Torsion spring can be attached to the adjusting shaft and the support part must, since the torsion spring acting in both directions of rotation of the control shaft Actuates. Furthermore, vibrations of the motor vehicle can increase loosen the fastenings of the torsion spring.
  • the control shaft usually has a slot in the torsion spring is inserted.
  • the invention is based on the problem of a load adjustment device of the type mentioned in such a way that they are particularly inexpensive is constructed and that the torsion spring is particularly reliable the support part is attached.
  • This design allows the torsion spring in both directions Actuating shaft transferring acting forces to the support part without it can detach itself from the support part. Vibrations of the Motor vehicle also no longer lead to a loosening of the torsion spring from the support part. As a result, the torsion spring is positive and thus attached particularly reliably to the support part. Grasping one Part of the support part by the torsion spring is compared for screwing particularly inexpensive.
  • the torsion spring is attached to the support part in accordance with an advantageous development of the invention is particularly constructive simply when the second end of the torsion spring pivots the support member is designed around. This must result in the second end of the Torsion spring for assembly is simply plugged onto the pin of the support part become.
  • the second end of the torsion spring is advantageous according to another Further development of the invention on the support part is particularly reliable held when the second end of the torsion spring is bent in a U-shape and at its free end a spring tongue pointing towards the base of the U. Has.
  • Disengaging the second end of the torsion spring from the pin of the support member in the direction of the axis of the pin can be according to another simply avoid advantageous development of the invention if the pin of the support part spans the second end of the torsion spring is designed.
  • the second end of the torsion spring is advantageous according to another Development of the invention secured in all directions against loosening, if the pin of the support part has a recess for receiving the second end of the torsion spring.
  • the torsion spring is according to another advantageous development Invention simply secured against tilting when the support member has a base plate for guiding the torsion spring.
  • a jamming of the torsion spring on an edge of the support part can be done according to another advantageous development of the invention, if the support part has several in its radially outer regions Has stops to limit the radial extent of the torsion spring.
  • the invention permits numerous embodiments.
  • the housing connector 1 shows a load adjustment device with a pivotable on a housing stub 1 supported part 2.
  • the center of the housing connector 1 is an adjusting shaft 3, which is, for example around a throttle valve shaft with a not shown Throttle valve can act, also pivotally mounted.
  • the control shaft 3, which is welded to the support part 2, for example, or a Forms unit is connected to the support part 2 via a torsion spring 4 and can by a reversible actuator 5 via a To simplify the drawing, pivot the gear (not shown).
  • the actuator 5 has a driver 6 for deflecting one Swivel arm 7 of the support part 2.
  • the support part 2 has a stop arm 8 on the movement of the support member 2 between a Minimum load stop 9 and an emergency stop 10 limited.
  • the support part 2 has a base plate 11 for guiding the torsion spring 4 and in its radially outer areas several stops 12 to 14 for limitation the radial extension of the torsion spring 4.
  • the actuating shaft 3 has a slot 15 for fastening the torsion spring 4 in which one end of the torsion spring 4 is inserted.
  • the second The end of the torsion spring 4 is bent in a U-shape and has one in the direction of The base of the U-pointing spring tongue 16 for engaging behind a pin 17 of the support part 2.
  • FIG. 3 shows a further embodiment of the fastening of the Torsion spring 4 on the support part 2.
  • the support part 2 has a vertical to the base plate 11 arranged pin 18.
  • the pin 18 will encompassed by a U-shaped end of a torsion spring 4.
  • the End of the torsion spring 4 has a bend 19 for engaging in one Recess 20 of the pin 18.
  • Figure 4 illustrates in a sectional view along the line IV - IV by Figure 3 the attachment of the torsion spring 4 on the pin 18. Here it can be seen that the bend 19 from a corner of the free end the torsion spring 4 is formed.
  • the pin 17 of the support member 2 is the second End of the torsion spring 4 is designed to span.
  • the torsion spring 4 has a bevel 21 at its second end in the longitudinal direction on.
  • the pin 17 has a bend 22, for example, by Stamping from the originally straight pin 17 is formed.
  • the Slant 21 of the torsion spring 4 and the slope of the bend 22 run parallel, the bend 22 overlaps the slope 21 of the torsion spring, so that the torsion spring 4 after insertion under tension from the interplay of bevel 21 and overall bending 22 is fixed in position.
  • FIG. 6 illustrates in a sectional illustration along the line V - V through Figure 5 the attachment of the torsion spring 4 on the pin 17.
  • the bend 22 the second end of the torsion spring 4th overlaps.
  • the assembly takes place, for example, in such a way that the torsion spring is held under tension by an assembly tool and that U-shaped second end (when viewing Figure 6 from the left) at a distance is brought to the pin 17 and then moved laterally, so that the slope 21 gets under the bend 22.
  • the torsion spring 4 is under its target tension and thereby pulls the slope 21 further under the bend 22 until the position is fixed.
