Definitions

  • the invention relates to a starter generator for an internal combustion engine and a method for producing the same with the features mentioned in claims 1 and 9.
  • Starting systems for internal combustion engines are known from the prior art, which generally consist of a battery-powered direct current motor (starter generator) and switching and control devices.
  • starter generator To start the internal combustion engine, a torque is transmitted from the starter generator.
  • Gasoline engines generally require speeds of 60 to 100 rpm and diesel engines require speeds of 80 to 200 rpm.
  • Numerous modifications to the starter system have been developed in the course of progressive weight and installation space reductions and improvements in starting performance.
  • an additional gear stage can be used to generate a total ratio of one generated by the starter generator.
  • th armature torque can be increased.
  • the starter generator has a rotor and a stator, the components of which essentially consist of layered and joined smells.
  • the sheets forming the stator and the rotor are connected to one another by joining.
  • the joining can be done by punching packages,
  • the individual sheets are pretreated and stacked on top of one another in such a way that the essential components of the two components are at least largely preformed.
  • the components of the rotor preferably include individually or in combination a hub, a bearing seat and a pulse wheel for speed and / or direction of rotation detection. If additional short-circuit bars or short-circuit rings are to be produced on the rotor, this can preferably be done by casting aluminum or casting copper.
  • a drilling pattern and a cooling system can be generated directly.
  • part of the cooling system is formed by cutouts on the outer edge of the stator.
  • the recesses then serve in a subsequent manufacturing step to accommodate cooling tubes.
  • the cooling tubes have knurling on their tube surface, which increases a holding force on a base body of the stator.
  • the cooling tubes can still be pressed in for permanent fixation on the stator or initially only inserted into the recess of the stator in order to then be expanded by a mandrel.
  • the cooling system can be accommodated inside the stator (internal cooling) or the jacket surfaces of the cooling system are formed by an outer edge of the stator and a gear bell housing the stator (external cooling).
  • To seal the cooling system can be in the area of the jacket surfaces of the cooling system Sealants are applied, for example a galvanic coating, a heat-resistant and coolant-resistant varnish or a synthetic resin. Further preferred embodiments of the invention result from the other features mentioned in the subclaims.
  • FIG. 1 shows an embodiment of a starter generator as an asynchronous machine in a perspective
  • FIG. 2 shows two perspective partial sectional views of a stator with a cooling system
  • FIG. 3 shows two perspective partial sectional views of a rotor
  • Figure 4 is a schematic sectional view of a stator with an inner one
  • Figure 5 is a schematic sectional view of an area of a stator with an external cooling. Description of the embodiment
  • FIG. 1 shows a starter generator 10 as it is mounted in the drive train between a crankshaft of an internal combustion engine and a gearbox connected in series.
  • a crankshaft starter generator 10 can be designed as an asynchronous machine and usually consists of a stator 12 and a rotor 14 movably mounted thereto.
  • a base body 15 of the rotor 14 is produced by joining different metal sheets, for example by means of punched packaging technology.
  • the base body 15 already contains all the essential components of the rotor 14.
  • its geometry is defined such that a bearing seat 16 is formed on the inside diameter of the rotor sheet metal.
  • the base body 15 has on its inner side a toothing 17 directed radially inward, which for example can be the starting point for speed and / or direction of rotation detection by means of a pulse wheel.
  • a further toothing 19 is produced on the outside of the base body 15 by the suitable configuration of the metal sheets forming the base body 15.
  • Short-circuit elements such as a short-circuit ring 18 and short-circuit rod 20, can be cast on this toothing 19 or in this gripping manner.
  • a copper or aluminum casting technique known per se can be used, whereby the first method enables a more favorable electrical efficiency. These methods can be carried out directly on the base body 15.
  • the stator 12 shown in FIG. 3 in two different perspective views is also produced by layering and joining different metal sheets. In this way, it is possible in this way to form essentially structural elements of the stator 12 in a manufacturing process.
  • pin bores 24 and cutouts 26 for receiving a cooling tube 28 (cooling system 27) can be provided.
  • heat transfer from the stator base body 22 to the cooling tube 28 can be improved by measures such as knurling the tube surface, pressing the cooling tube 28 into the stator package or inserting the cooling tube 28 into the stator package and then expanding it with a mandrel. Overall, this allows for very flexible local taking into account.
  • FIGS. 4 and 5 two alternative cooling systems 27 for the stator 12 are each shown in a schematic quarter-section.
  • Internal cooling (FIG. 4) can be implemented in such a way that the base body 22 is welded in the axial direction, in each case, with two end plates 29 of the same size.
  • An outer jacket surface of the cooling system 27 is formed via a pipe section 32 welded to the end plates 29.
  • a sealant 36 is applied in the area of the lateral surfaces 34 by means of a coolant which is circulating in operation.
  • the sealant 36 can be a galvanic coating, a heat-resistant and coolant-resistant lacquer or a synthetic resin.
  • Such an integrated cooling can reduce the construction volume and the weight of the stator 12.
  • its recycling capability is improved by the restriction of the number of materials used, and cooling can take place with a particularly favorable heat transfer.
  • a wall 38 in which the stator 12 accommodates the stator 12 can also be used. If such a configuration meets the local requirements of the stator generator 10, a further weight reduction can be achieved in this way.
