Abstract

Die Erfindung betrifft eine Variable Turbinengeometrie (1) für eine Ladeeinrichtung (2) mit einem Schaufellagerring (3), an welchem mehrere Leitschaufeln (4) drehbar gelagert sind und einem relativ zum Schaufellagerring (3) verdrehbaren Verstellring (5) zum simultanen Verdrehen der Leitschaufeln (4). Erfindungswesentlich ist dabei, dass der Verstellring (5) den Schaufellagerring (6) zumindest teilweise koaxial umfasst, und dass eine Federeinrichtung (6) vorgesehen ist, die den Verstellring (5) in Radialrichtung zum Schaufellagerring (3) elastisch vorspannt. Hierdurch kann das Hystereseverhalten positiv beeinflusst werden. Eine entsprechende Ladeeinrichtung wird ebenfalls präsentiert.

The invention relates to a variable turbine geometry (1) for a loading device (2) with a blade bearing ring (3) on which a plurality of guide vanes (4) are rotatably mounted and an adjusting ring (5) rotatable relative to the blade bearing ring (3) for simultaneously rotating the guide vanes (4). It is essential to the invention that the adjusting ring (5) at least partially coaxially surrounds the blade bearing ring (6), and that a spring device (6) is provided which elastically biases the adjusting ring (5) in the radial direction to the blade bearing ring (3). As a result, the hysteresis behavior can be positively influenced. A corresponding charging device is also presented.
