Abstract
A variable turbine geometry (VTG) exhaust-gas turbocharger in which guide vanes are adjusted by means of a unison ring, the structure of which has a simpler and thus more cost-effective design. The number of components is reduced, for example for rollers on pins as are provided in the case of known bearings. A very beneficial relationship between friction radius and rolling radius in the given installation space is obtained.
