    Abstract: The invention relates to an exhaust gas turbine, comprising a turbine wheel (7) with a multiplicity of moving blades (8) and an exhaust-gas outlet duct (15), which is arranged downstream of the moving blades of the turbine wheel. The exhaust-gas outlet duct (15) is delimited radially on the outside by an axial turbine diffuser (1) and radially on the inside, at least partially, by a spinner (2). The axial turbine diffuser (1) is formed by a number N>1 of successive conical diffuser segments. An axial diffuser opening angle A between successive diffuser segments is A>1.0°. A ratio L/H between an axial diffuser segment length L and an entry height H of the exhaust-gas outlet duct (15) is L/H>0.01. A ratio H/S between the entry height H of the exhaust-gas outlet duct and a maximum radius S of the spinner (2) is H/S>1.0. The spinner (2) is formed by a number P>1 of successive conical spinner segments. An axial spinner opening angle B between successive spinner segments is B>1.0°. A ratio M/H between an axial spinner segment length M and the entry height H of the exhaust-gas outlet duct (15) is M/H>0.01.

    Abstract: Exemplary embodiments of the present disclosure are directed to a 2-stage supercharging unit having a housing unit which integrates within it a high-pressure charger and a low-pressure charger. The rotor axes of the two chargers are vertical with respect to the housing unit, which can be screwed directly via the housing base to the side of an internal combustion engine. As a result, increased flexibility is made possible with regard to the connection of the supercharging unit to the cooler and to the internal combustion engine, whereby the structural volume of the supercharging assembly can be additionally reduced.

    Abstract: An exemplary arrangement for securing the shaft of an exhaust-gas turbocharger includes a catch ring with a central opening and a radial projection on the shaft. The catch ring having an inner contour in the region of the central opening. The radial projection on the shaft is provided with an outer contour. The inner contour on the catch ring and the outer contour on the shaft are configured such that, during mounting of the shaft and of the turbine wheel connected thereto and in at least one specified angle position of the shaft with respect to the housing, the radially outwardly protruding projection on the shaft can be passed in an axial direction through the central opening of the housing element. The radially outwardly protruding projection abuts in the axial direction against the housing element in specified angle positions of the shaft with respect to the housing.

    Abstract: The shaft (1) is connected to the shaft attachment (2) by means of a thread. A bore (20) with an internal thread is incorporated in the shaft attachment and the shaft has a corresponding stem (10) which can be introduced into the threaded bore and has an external thread. An axial stop (11, 21) is arranged in each case on the shaft and on the shaft attachment. The internal and external threads have torque-transmitting flanks which are flat toward the axis and which can be connected to one another frictionally by means of radial pressure by mutual rotation of shaft and shaft attachment with interaction between the axial stops. Owing to the small angle between the load-bearing flanks and the axis, the radial pressure decisive for the torque transmission is correspondingly greater than in conventional threaded connections. As a result, the axial prestressing force between the two parts to be connected can be correspondingly reduced.
