Definitions

  • the invention relates to the crankshaft of an engine with at least two Driven on a common shaft section by means of a in essential axially directed clamping force are braced against each other.
  • the invention relates in this context Crankshafts with a pulley and a sprocket as output, like these for the operation of oil pumps, camshafts, alternators and similar find in motor vehicles use.
  • GB 2 013 835 A proposes within a recess of the output lying to the crankshaft Keilringcrue to be provided, which in the axial clamping of two drives against each other lead to a radial wedging of a driven wheel.
  • the invention proposes a crankshaft with the features of claim 1 before.
  • the clamping element or the deflection means arranged between the two drives, so that by a single additional assembly of the desired effect can be achieved. This allows a relatively inexpensive realization of Invention.
  • the deflection or the clamping element integrally connected to one of the power take-offs and to the cone-shaped one Area in a corresponding recess of the other output be arranged. This allows for an additional, separate assembly completely waived.
  • the deflection or the clamping element are only suitably formed at the respective output. This contributes to a further cost reduction on the one hand in the production and on the other hand, during assembly.
  • the latter arrangement is suitable especially for sprockets that are accurately positioned in the axial direction should be to ensure a smooth running of the chains.
  • crankshafts shown in the figures are two outputs, namely sprockets 2, 2 ', 2 "and pulleys 3, 3' 'on one Shaft journal of a crankshaft 1 by means of a clamping screw 4 and a Washer 5 braced against a shaft shoulder 6.
  • FIG. 1 In the embodiment shown in Figure 1 is between the Sprocket 2 and the pulley 3 as a clamping element a clamping ring. 7 arranged. This has two cone-shaped or conical areas on, in corresponding recesses of the sprocket 2 and the Pulley 3 are arranged.
  • the bracing takes place both in these embodiments with regard to the crankshaft 1 as well as with regard to the power take-offs 2, 2 ', 3, whereby a particularly high fixation is guaranteed.
  • inventive Embodiments are the angle of the clamping elements 7, 7 'and the corresponding recesses preferably between 15 ° and 30 °.
