Definitions
- the invention relates to a load adjusting device for determining the performance of an internal combustion engine, in particular designed as a throttle, arranged on a control shaft in a housing actuator, wherein the actuating shaft via a non-rotatably connected thereto actuator part by means of a reversibly driven
- This training requires a large axial and radial size.
- the object of the invention is therefore to provide a load adjustment device of the type mentioned, which avoids these disadvantages, allows an axially low profile and is easy to assemble and disassemble.
- This object is achieved in that the actuating part can be acted upon by a leg of a torsion spring, which is fixedly arranged radially outside the pivoting range of the actuating part, wherein the leg of the torsion spring projects into the pivoting range of the actuator.
- This training allows a construction of low height.
- the arrangement of the torsion spring can be done at any and thus easy to assemble location around the pivoting range of the control part, as well as be arranged with considerable radial distance thereto.
- the torsion spring is largely independent of the structure in the range of the control shaft and the actuator, it can be designed with great variable design in shape, wire thickness, diameter, etc.
- the torsion spring has one or more turns, from the center of which the leg extends outwards.
- a simple plug-in assembly is thereby possible if the turns of the torsion spring enclose a dome fixed to the housing.
- the torsion spring may have a second leg extending away from the center, which is supported in a simple manner on the housing against rotation about the center of the torsion spring.
- the second leg is supported on one or more stops fixed to the housing.
- a particularly flat configuration results from the fact that the one or more legs of the torsion spring extend at least approximately in the plane of the pivoting range of the adjusting part.
- the actuating part can have a stop by which the leg of the torsion spring is acted upon.
- the actuating part may be a toothed segment into which a drive pinion rotatably driven by the actuating drive engages, wherein the drive pinion may be part of a transmission.
- the actuator is a reversible electric motor.
- the leg of the torsion spring forms the full load stop.
- the actuating part is a toothed segment, since then the risk of tooth fracture is substantially reduced by the lower tooth load when the toothed segment is hit against the full-load stop.
- the torsion spring is a Notertonfeder by which approach the actuator from one of the minimum load position Position in full load direction to an emergency position of the actuating shaft movable acted upon.
- This training allows easy to install and disassemble the emergency spring.
- the return spring may be a coaxially arranged to the rotational axis of the actuating shaft second torsion spring.
- the load adjusting device shown in the drawing has a housing forming a throttle body 1 with a flow opening in which a throttle valve, not shown, is fixedly mounted on a control shaft 2.
- the pivotally mounted in the throttle body 1 actuator shaft 2 carries rotatably on its protruding from the flow end rectangular cross-section a toothed segment 3, in which a drive pinion 4 engages.
- the drive pinion 4 is non-rotatably mounted on a rotatably mounted transmission axis 5, on which a further gear 6 is rotatably mounted, which in turn is rotatably driven by a driven pinion, not shown, of a reversible electric motor 7.
- the sector gear 3 is pivotally driven by the electric motor 7 between a minimum load stop 8 and a trained as the first leg 9 of a torsion spring in both directions of rotation at which the toothed segment 3 comes with its directed in the direction of rotation stop surfaces forming ends to the plant, of which the minimum Load stop 8 facing stop surface 10 is shown.
- the throttle body 1 Radially outside the pivoting range of the toothed segment 3, the throttle body 1 has a parallel to the control shaft 2 fixed, protruding dome 11, which has a turn 12, formed as a torsion spring emergency running spring 13 with its winding 12 encloses.
- the emergency running spring 13 has a first leg 14 extending away from its center and a second leg 15 extending away from the first leg 14 approximately in the opposite direction to the outside.
- the second leg 15 is supported on a fixed stop 16, which prevents rotation of the emergency running spring 13 in the clockwise direction.
- a driver stop 17 is arranged on the toothed segment 3, at which the free end portion of the first leg 14 of the emergency spring 13 can come to rest when the driver stop 17 in an area between the
- Minimal load stop 8 and the pivoting of the first leg 14 in the full load direction limiting emergency stop 18 is located.
- the emergency stop 18 defines an emergency stop position.
- the force acting on the sector gear 3 by the emergency running spring 13 in the full load direction is greater than the force acting on the sector gear 3 in the minimal load direction by the restoring spring.
- the toothed segment 3 can be driven by the electric motor 7 in the minimal load direction until the abutment surface 10 abuts against the minimum load stop 8. In this case, after reaching the first leg 14 by the driver stop 17 of the first leg 14 is deflected.
- the throttle valve is in an emergency operation of the internal combustion engine ensuring opening degree.
- the toothed segment 3 pivots until it comes to rest with its second stop surface, not shown, for engagement with the first leg 9 forming the full-load stop and deflects this to a certain extent.
- the torsion spring has a turn 219 with which it encloses a fixed second mandrel 20.
- a second leg 21 of the torsion spring is supported on a fixed second stop 22, which prevents rotation of the torsion spring counterclockwise.
