Definitions
- a generator is known from a publication by Bosch in the series Technical Information, "Generators”, edition 98/99, on which a cover cap with an intake port is placed at one axial end. A hose is connected to this air intake, so that the generator is only cooled by cool air from outside the engine compartment. While the generators are usually cooled by air which has already been preheated in the engine compartment by the internal combustion engine to a temperature level above the outside temperature, air is sucked in from outside the engine compartment, which is thereby much cooler.
- connection and the air duct center line it is possible to achieve the best possible use of space for the air duct despite the given coaxiality of the air duct and the connection for the further suction element.
- a conical, stepless course tapering towards the center of the cover cap achieves, on the one hand, a targeted inflow of temperature-critical components and, in turn, a flow-favorable course.
- a further improved course of the air guidance is achieved in that the conical course of the air guidance already begins at the air inlet opening. This makes good use of the space within the connection for the further suction element.
- a favorable arrangement for the webs with regard to their support effect for a hose to be pushed on is given when these webs have cutouts in the form of a hexagonal honeycomb structure.
- annular bead-like elevations are arranged at least over part of the cylindrical surface of the connection.
- FIG. 1 shows a three-dimensional view of the cover cap according to the invention with the intake socket
- Figure 4 is a plan view of the cover cap. Identical or identically acting components are identified by the same reference numbers.
- FIG. 1 shows a partial view of an axial end of a generator 10.
- a substantially pot-like cover cap 16 is placed on a bearing plate 13, which usually accommodates a bearing (not shown) for a claw pole rotor (also not shown).
- This cap IS has an intake manifold 19 which forms an air guide 22 and has a connection 25 for a further suction element 28 ..
- the air guide 22 extends in 'toward a center 31 of the cap 16 and divided into two .Luft Adjustskanäle 34 and 37 The flowing through an air inlet opening 40
- Cooling air is passed through the air duct 22, the cooling air flow being divided into essentially two cooling air partial flows, which are directed to temperature-critical components.
- FIG. 2 shows a section through the air duct 22 as indicated in FIG. 4. It can be clearly seen that the air duct 22 has a conical and stepless course.
- the connection 25 of the intake manifold 19 has an essentially cylindrical surface 43, onto which the further intake element 28 can be pushed and fastened.
- This essentially cylindrical surface 43 of the connection 25 forms the outer circumference 46 of the connection 25 and has a central axis 49.
- the essentially cylindrical surface 43 or the outer circumference 46 of the connection 25 can also be seen in FIG.
- Axis 49 of the outer circumference 46 of the connection 25 has a different direction in the region of the connection than the air guiding center line 52.
- This design of the air duct 22 in the area of the connection 25 enables a streamlined design due to its largely independence from the cylindrical surface 43 of the connection 25.
- Another feature of the air duct 22 or its air duct center line 52 and the central axis 49 is given by the fact that the axes 49 and the air duct center line 52 intersect.
- the conical course of the air duct 22 already begins at the air inlet opening 40.
- the air duct 22 or the air duct center line 52 runs in an arc-shaped manner towards the center of the cover cap 16 in a streamlined manner.
- FIG. 3 shows a side view of the cover cap 16 according to the invention on the end shield 13.
- a regulator 55 and a rectifier 58 shown symbolically here, are arranged between the end shield 13 and the cover cap 16. Because the cover cap 16 only has air access in the form of the air duct 22 and the cooling air flow can be directed in a targeted manner, it is possible to cool the controller 55 and the rectifier 58 in a targeted and effective manner.
- At the connection 25 or its outer circumference 46 there are annular bead-like elevations 61 which serve to clamp a tube 64 pushed on from the inside thereof.
- a hose clamp 65 or a similar mounting part it is therefore possible to obtain a good and secure connection of a hose 64 to the intake connector 19, see also FIG. So that the clamping between the hose 64 and the intake 19 or, respectively, the connection 25 during the pushing on is not too great, the annular bulges are Elevations 61 only extend over part of the cylindrical surface 43.
- the fact that a conical air duct 22 is arranged within the cylindrical surface 43 of the connection 25 results in a so-called differential volume 67 in the cover cap 16 on the surface of the air duct 22 facing away from the end shield 13.
- the differential volume 67 can be described by the fact that it is the difference between the cylindrical part of the connection 25 and the conical part of the air duct 22 over the length of the connection 25.
- This difference volume can be seen in FIG. 2 from the triangular area between the cylindrical surface 43 and the air duct 22 over the length of the connection 25. It can also be seen in FIG. 3 and in FIG. 1.
- webs 70 are arranged which, for example, support a hose 64 from the inside and thus provide an essentially cylindrical outer surface corresponding to the cylindrical surface 43. The webs are arranged so that a
- FIG. 4 shows a top view of the cover cap 16 or its intake 19.
- Various other suction elements are attached to such a connection 25 28 connectable.
- a connection 25 28 connectable.
- a hose 64 can be connected or, as shown in the upper part of the connection 25, a tube 79.
- honeycombs which are enclosed by the webs 70, can not only be rectangular, as shown for example in FIG. 1 or FIG. 4, but also, for example, have a hexagonal honeycomb structure.
