Definitions

  • the invention relates to a device with at least one throttle valve located within an intake bore, which is arranged on a shaft.
  • Devices of this type are used, for example, in suction and dosing devices in internal combustion engines in order to feed the exhaust gases of the engine back to combustion.
  • the supply of the exhaust gases is controlled by means of a plurality of throttle valves, the throttle valves being pivotable about 90 ° via the shaft. Screws are usually used to attach the throttle valves to the shaft. Such an attachment requires a considerable manufacturing effort.
  • the object of the invention is therefore to provide an improved device of the type mentioned, in which the function of the throttle valve and the shaft is reliably maintained.
  • the throttle valve In order to maintain the welded joint, the throttle valve is welded onto the shaft at at least one point. As a result, the throttle valve is sufficiently secured to the shaft and the considerable mechanical Manufacturing effort as in the prior art is eliminated. If the throttle valve is to be detached from the shaft again, this is done by a slap on the back of the throttle valve, which breaks the welded joint.
  • a particularly preferred embodiment of the invention consists in that two welded connection points lying next to one another in the axial direction of the shaft are provided.
  • these two welded joints can be arranged symmetrically to the center of the throttle valve and the edge of the throttle valve. This prevents the throttle valve from bending away from the shaft during intensive use.
  • the throttle valve is always on one level and lies directly on the shaft.
  • the welded connection points are expediently designed as laser welded connection points, which can be produced by means of a laser spot welding device.
  • a further embodiment of the invention provides that a stamping is provided on the shaft and a recess in the throttle valve is provided for receiving the stamping.
  • the recess is advantageously arranged in the middle of the throttle valve.
  • the throttle valve In its maximum closed position, the throttle valve does not lie completely against the inner walls of the intake bore, but encloses an angle of 3 ° with a plane perpendicular to the intake bore.
  • the device according to the invention consists of a base body 1 with an upper side 2 and an underside 3. Eight continuous suction bores 4, each with an inlet 5 and an outlet 6, extend from the upper side 2 to the underside 3. All suction bores 4 extend radially and approximately in half the depth of the bores, a continuous shaft 7, which is mounted within the base body 1.
  • a throttle valve 8 is fastened on the shaft 7 within four of the eight bores 4.
  • two welded connection points 9 are provided between each throttle valve 8 and the shaft 7, which are arranged next to one another in the axial direction 10 of the shaft 7.
  • the welded joints 9 are symmetrical to the center 11 of the throttle valve 8 and are arranged near an edge 12 of the throttle valve 8.
  • the throttle valve 8 has a rectangular recess 13, symmetrical to its center 11, into which a rectangular shape 14 of the shaft 7 projects. By means of this characteristic 14, the throttle valve 8 can be fixed on the shaft 7 in the circumferential direction 17.
  • the recess 13 is located in the region of a dome-shaped elevation 15 of the otherwise disk-shaped throttle valve 8.
  • the elevation 15 extends radially over the throttle valve and has such a curvature that it bears on the shaft 7 when the throttle valve 8 is fitted.
  • sleeves 16a and 16b provided, which are located within the base body 1 and are flush with the inner walls of the suction bores 4. The sleeves serve to support the shaft within the base body 1.
  • the throttle valve 8 is arranged between two of these sleeves 16, they can also serve as a stop for the edge 12 of the throttle valve 8.
  • the distance dimensions between two sleeves 16a and 16b are chosen so that they correspond to those between the two flattened end edge surfaces 18a and 18b of a throttle valve 8, so that the throttle valve is axially fixed in the direction of arrow 10 in FIG. 2 by the interaction of sleeves and end edge surfaces the wave occurs.
  • the plane of the throttle valve 8 lies in a plane which is spanned by the axis of the shaft 7 and the central axis of the intake bore 4.
  • the throttle valve 8 lies in a plane which is inclined by 3 ° with respect to a plane spanned by the axial direction 10 of the shaft 7 and a radial central axis of the bore 4.
  • the edge 12 of the throttle valve 8 does not lie completely against the inner wall of the bore 4, but the throttle valve is located somewhat above and below the shaft 7, as seen from the shaft 7.
  • the throttle valve 8 is attached to the shaft 7, the throttle valve 8 is first placed on the shaft 7 in such a way that the shape 14 engages in the recess 13, the dome-shaped elevation 15 abutting the shaft 7. This allows the throttle valve 8 to be fixed in the circumferential direction 17. In the axial direction, it is fixed by the interaction of the end edge surfaces and the sleeves. The throttle valve 8 is then spot-welded onto the shaft 7 at two points using a laser spot welding device in order to produce the welded connection points 9. Thus, the throttle valve 8 is attached to the shaft 7 in a simple manner. Through the suction holes 4, gases can then be sucked through, the degree of passage being determined by the position of the throttle valve 8, which is actuated by the shaft 7.
