Definitions
- the invention relates to a housing for a load adjustment device one the performance of an internal combustion engine determining, in particular designed as a throttle Actuator, with two housing parts for receiving a Transmission and / or a reversible actuator the load adjustment device and with a fastening means for the positive connection of the housing parts among themselves; see, e.g. D E-A-19540586.
- Housing of the above type are usually on a throttle body attached and are of internal combustion engines For example, known from motor vehicles.
- the housing parts take the commonly referred to as e-gas Load adjustment on.
- the known housing has one of the housing parts latching hook for grasping behind of recesses of the other housing part.
- the latching hooks are one-piece with their housing part manufactured.
- a disadvantage of the known housing is that through the locking hooks no great biasing forces on the housing parts transfer. This is a permanent Leakage of the housing is not guaranteed.
- the invention is based on the problem, a housing of the the type mentioned above so that a permanent Tightness is reliably guaranteed.
- the housing parts can be at appropriate Design of the metal strip with very large Forces are biased against each other. Continue to be punctual loads on the housing parts, as they often do arise with a small number of latching hooks, at a correspondingly wide design of the metal strip avoided. Cracks the housing parts leaves Therefore, thanks to the invention simply exclude. As a result, a very large tightness of the housing is ensured.
- Another advantage of this design is in that the housing parts in each case particularly inexpensive to manufacture, because no latching hook and Breakthroughs are required for the latching hooks.
- the transferred from the sheet metal strip on the housing parts Preload forces can be according to an advantageous Development of the invention evenly over the adjacent Distribute areas of the housing parts when the metal strip one for Hintergreifung a circumferential, designed on one of the housing parts arranged edge Beading has.
- the metal strip with its edges one circumferential each Behind grab the edge of the housing parts, with one of the Schugreifonne may be preformed on the sheet metal strip, while the other Schugreifung during the assembly of the housing is generated by the bead.
- the housing according to the invention has very few to be mounted Components, if the cup-shaped to the sole Recording a transmission of Lastverstellvorraum designed Housing part has the peripheral edge and if the housing part forming a cover integral with the sheet metal strip is made.
- the one-piece design of the metal strip with the housing part can be according to another advantageous Develop the invention easily, if one the housing parts made of plastic by injection molding is and if the sheet metal strip on this housing part is injected. For spraying the metal strip thereby simply into the injection mold of the housing part be inserted. When filling the injection mold Plastic is the metal strip with the housing part connected.
- the metal strip is advantageous according to another Development of the invention reliably with the housing part connected when the metal strip in his from the Housing part encapsulated area an angled portion or recesses having.
- the metal strip could be made of almost any material be made. However, the metal strip has one very light weight and can handle the housing parts permanently connect with each other when the sheet metal strip made of aluminum.
- the metal strip could, for example, several from each other have separate sections.
- the assembly of the invention Housing is designed especially cost-effective if the metal strip in the entire adjoining Area of the housing parts designed circumferentially is.
- FIG. 1 shows a housing 1 for a load adjustment device an internal combustion engine of a motor vehicle with a cup-shaped housing part 2 and a lid formed housing part 3.
- the cup-shaped housing part 2 holds a designed as an electric motor, reversible Actuator 4.
- the actuator 4 is over a Gear 5 is connected to a throttle shaft 6.
- the Throttle valve shaft 6 is used to move a not shown, in particular designed as a throttle Actuator. About the throttle can be the power of the internal combustion engine.
- the housing 1 is with a between the housing parts 2, 3 arranged Seal 7 sealed.
- the housing parts 2, 3 each have a circumferential edge 8, 9.
- the circumferential edges 8, 9 are each engaged behind by a metal strip 10.
- the metal strip 10 has on his at the as Cover formed housing part 3 adjacent area a preformed edge 11 and at the edge 9 of the cup-shaped Housing part 2 adjacent area a bead 12.
- a correspondingly stable design of the metal strip 10 can be the housing parts 2, 3 with large Pretend forces against each other. Since the metal strip 10th around the entire housing 1 is designed to be circumferential the biasing forces uniformly over the housing parts 2, 3rd distributed. The very wide-shaped seal 7 prevents also selective loads on the housing parts 2, 3.
- Figure 2 shows a side portion of a housing 13 in the longitudinal section. This is in a housing part 14th a metal strip 15 molded.
- the housing part 14 is made of plastic by injection molding.
- the out the lid formed as a housing part 14 outstanding Area of the metal strip 15 has an edge 16 of a pot-shaped housing part 17 engaging behind flanging 18.
- In his from the designed as a lid housing part 14 coated area has the metal strip 15th an angling 19.
