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 °.

Claims (3)
- Kurbelwelle (1) eines Motors mit zumindest einem ersten (2, 2', 3) und einem zweiten (3, 2, 2') Abtrieb, die auf einem gemeinsamen zylindrischen Wellenabschnitt mittels einer im Wesentlichen axial gerichteten Spannkraft gegeneinander verspannt sind, dadurch gekennzeichnet, dass am ersten (2, 2', 3) und am zweiten (3, 2, 2') Abtrieb je ein konus- bzw. kegelförmiger Bereich (7') ausgebildet ist, über welche Bereiche (7') die axial gerichtete Spannkraft in Spannkräfte mit einer radialen Komponente umgelenkt wird, welche auf den ersten (2, 2', 3) bzw. den zweiten (3, 2, 2') Abtrieb wirken.
- Kurbelwelle nach Anspruch 1, dadurch gekennzeichnet, dass der erste Abtrieb (2, 2', 3) und der zweite (3, 2, 2') Abtrieb jeweils eine konus- bzw. kegelförmige Ausnehmung aufweisen und ein Spannelement (7, 7') mit zwei konus- bzw. kegelartigen Bereichen vorgesehen ist, die in den Ausnehmungen der beiden Abtriebe (2, 2', 3) angeordnet sind.
- Kurbelwelle nach Anspruch 1, dadurch gekennzeichnet, dass der erste Abtrieb (2, 2', 3) Spannlippen (7') mit konus- bzw. kegelförmigen Bereichen aufweist und die Spannlippen (7') in einer konus- bzw. kegelförmigen Ausnehmung des zweiten Abtriebs (3, 2, 2') angeordnet sind.
