Abstract

In an exhaust-gas turbocharger with a shaft axially arranged between a compressor wheel and a turbine wheel and connected in a rotationally fixed manner to the compressor wheel as well as to the turbine wheel, said shaft being rotationally mounted with a turbine-side shaft part in a turbine-side bearing, a connecting region with minimal heat conductivity is axially arranged or configured between the turbine-side shaft part and the turbine wheel in such a manner that the heat flow emanating from the turbine wheel is choked.
