The invention relates to a rotor () for an electric rotating machine (), in particular a synchronous machine (), comprising a shaft () and at least one pole shoe (). In order to keep overhead and costs low while achieving high reliability, according to the invention, a metal sheet () is placed between the shaft () and the pole shoe (); said metal sheet () has a first contact area () that is in contact with a contact area () on the pole shoe (), the metal sheet () and the pole shoe () being made of different materials.

Rotor for an electric machine having a sheet metal for securing a pole shoe to a shaft

A rotor for an electric rotating machine, in particular a synchronous machine, includes a shaft and at least one pole shoe. The shaft has a first contact surface and the at least one pole shoe has a second contact surface. The first contact surface has a first profile and the second contact surface has a second profile corresponding to the first profile, with the first profile of the first contact surface lying on the corresponding second profile of the second contact surface in an interlocking manner.

Inlet pipes extend from a collector to the cylinder inlets of the internal combustion engine. The inlet pipes are formed with mutually facing openings in their adjacent walls. Control flaps each have a shaft, which is respectively provided with a damping element and is mounted by way of the damping elements in a bearing bush. The openings in the inlet pipes are selectively closed and opened with the control flaps.
