Abstract
Die Erfindung betrifft eine Ladevorrichtung (1), insbesondere einen Abgasturbolader für ein Kraftfahrzeug, mit einer ein Verdichterrad (2) tragenden Welle (3), mit einer Fixiereinrichtung (4) zum Fixieren des Verdichterrades (2) auf der Welle (3), mit zumindest einem auf der Welle (3) und durch die Fixiereinrichtung (4) zusammen mit dem Verdichterrad (2) fixierten Bauelement (5,6,7). Durch geschickte Auswahl von Materialien lässt sich erreichen, dass eine Wärmeausdehnung des Verdichterrades (2) durch den Ausdehnungskoeffizienten (α3)zumindest eines Bauelementes (5,6,7) zumindest teilweise kompensiert werden kann. Dadurch ist es möglich, die anfängliche Spannkraft, mit der die Bauelemente (5,6,7) auf der Welle (3) positioniert bzw. verspannt werden zu erhöhen, ohne dass die für die verspannten Bauelemente (5,6,7) zulässige Flächenpressung überschritten wird. The invention relates to a charging device (1), in particular an exhaust gas turbocharger for a motor vehicle, having a shaft (3) carrying a compressor wheel (2), with a fixing device (4) for fixing the compressor wheel (2) on the shaft (3) at least one component (5, 6, 7) fixed on the shaft (3) and by the fixing device (4) together with the compressor wheel (2). By skillful selection of materials can be achieved that a thermal expansion of the compressor wheel (2) by the expansion coefficient (α 3 ) of at least one component (5,6,7) can be at least partially compensated. This makes it possible to increase the initial clamping force with which the components (5, 6, 7) are positioned or braced on the shaft (3) without the surface pressure permitted for the braced components (5, 6, 7) is exceeded.
