Definitions

  • drive shafts are already known at those of the gear carrier and the actual one Drive shaft part made from a separate part and through an additional manufacturing process be inextricably linked.
  • One of these Known manufacturing processes consist of welding together of the gear carrier with the drive shaft part. adversely is in this joining together two different parts a drive shaft with gear carrier that the supplied Welding energy to a sharp rise in temperature of the Component and thus leads to a so-called welding distortion.
  • the drive shaft must be aligned separately so that the Drive shaft relatively expensive and complex in the Manufacturing is.
  • the force transmission from Gear carrier to the drive shaft unfavorable.
  • the starting device with the features of the independent Claim has the advantage that by simple Assembling the gear carrier with the drive shaft already a reliable power transmission between Gear carrier and drive shaft is made possible. About that In addition, a suitable one is for other components Choice of materials possible, so that without compromise a further optimized component can be generated. As Another advantage is that standard drive shafts can be formed and only by varying the Gear carrier already different configurations or Combinations of drive shaft and gear carrier possible are to meet the different requirements To be able to do translations.
  • an axial position of the Gear carrier at least indirectly between two stops is determined. This leads to a floating storage of the Gear carrier on the drive shaft and consequently thereby to the possibility of compensating for assembly misalignment in the case of larger tolerated components. Shape deviations of the individual Components are easily tolerated.
  • the camp can both forces Starting an internal combustion engine as well after Take overtaking the engine. Further Components, such as the actual one This makes planetary gears or even the starter motor not burdened. If you bring between the at least one of the Stops and the bearing each have a relative turntable, this way you can reduce friction and wear Storage between the stop and the bearing.
  • a particularly cheap power transmission and Material utilization is particularly suitable if between positive and counter positive between Drive shaft and gear carrier have involute teeth serves for power transmission.
  • one Involute toothing particularly suitable to play between the positive connections of the gear carrier and the drive shaft compensate.
  • a particularly efficient way of production arises when the form fit and / or the Counter positive locking are integrally molded.
  • Figure 1 shows a in a longitudinal sectional view Starting device according to the invention 10.
  • a partial Electric drive 13 shown drives via a Motor shaft 16 and a planetary gear 19 a drive shaft 22 on.
  • On the drive shaft 22 is a rotatable Single-track gear 25 arranged.
  • the motor shaft 16 is connected to the single-track gear 25 facing end with a gear element 28 that serves as the sun gear of the planetary gear 19.
  • a gear element 28 that serves as the sun gear of the planetary gear 19.
  • the planet gears 31 are by means of bearing elements 34 rotatably mounted on pin 37.
  • the bolts 37 in turn are fastened in a gear carrier 40.
  • the gear carrier 40 is a planet carrier in the example.
  • the gear carrier 40 is connected to the drive shaft 22.
  • the planet gears 31 not only roll on the gear element 28, but also within a so-called ring gear 43 from.
  • the ring gear 43 is with an intermediate bearing 46 connected.
  • the drive shaft 22 has the gear element 28 on one facing end a length section 49 with a Form fit 52.
  • Gear carrier 40 corresponds to the form fit 52 Counter positive locking 55.
  • the axial position of the gear carrier 40 is determined by that on the one hand on the gear element 28 facing A stop 58 is arranged at the end of the drive shaft 22, and another on the drive shaft 22 Stop 61 is arranged, the stop 58 and the Stop 61 between them at least the gear carrier 40 take up. This is the axial position of the gear carrier 40 at least indirectly between the two stops 58 and 61 certainly.
  • the Stop 61 formed as an axial locking ring, the Stop 58 on the drive shaft 22 is in one piece molded collar. This gear carrier side Stop 58 is thereby an inseparable stop 61.
  • the bearing element 73 can, for example designed as a plain bearing bush but also as a needle bearing his. Alternatively, a low-build one Cylindrical roller bearings with a laminated outer ring are used become. The bearing element 73 is thus between one Stop and the gear carrier 40 arranged.
  • FIG. Another embodiment is shown in FIG. In contrast to those shown in Figures 2 and 3 Arrangements of the drive shaft 22 in the intermediate bearing 46 points the drive shaft 22 the stop 58 at the Gear element 28 directed end.
  • the stop 58 is however on the side of the intermediate storage 46 Form-fit 52 arranged.
  • the two take Attacks 61 and 58 at least indirectly between them Interim storage facility 46.
  • the gear carrier 40 is placed on the positive connection 52; the planet gears 31 sit on the bolts 37 and engage in the gear member 28 a.
  • the axial position of the Planetary gear 19 is between one as a stop 61st acting cover 78 determined.
  • the cover 78 engages in Example in a circumferential recess 81 in which the Cover 78 is inserted.
  • the cover will either by adjacent components, not shown, or for example, by a positive or positive connection between the Cover 78 and the intermediate storage 46 in their position certainly.
