Abstract
A turbine housing for an exhaust gas turbocharger may include a wastegate valve that may have at least two apertures. A first aperture may be configured to receive a wastegate shaft and a second aperture may be configured as an inlet to a bypass channel. An insert may include a valve seat for the wastegate valve and a bearing bush for mounting the wastegate shaft. The valve seat may be mounted by a matching valve disc. The valve seat may cover the second aperture and the bearing bush may cover the first aperture in an installed state of the insert.

A turbine housing for an exhaust gas turbocharger, comprising:
- a wastegate valve including at least two apertures, a first aperture configured to receive a wastegate shaft and a second aperture configured as an inlet to a bypass channel;
- an insert including a valve seat for the wastegate valve and a bearing bush for mounting the wastegate shaft, wherein the valve seat is mounted by a matching valve disc;
- wherein the valve seat covers the second aperture and the bearing bush covers the first aperture in an installed state of the insert.
An exhaust gas turbocharger, comprising:
- a turbine housing having a first wall thickness, the turbine housing including a wastegate valve having at least two apertures, a first aperture configured to receive a wastegate shaft and a second aperture configured as an inlet to a bypass channel;
- an insert coupled to the turbine housing, wherein the insert defines a shaped angle having a first leg on one end and a second leg on another end;
- and
- a valve seat for the wastegate valve arranged on the first leg and a bearing bush for mounting the wastegate shaft arranged on the second leg, wherein the bearing bush covers the first aperture and the valve seat covers the second aperture, the valve seat including a complementary valve disc mounted thereon;
- wherein the insert includes a second wall thickness greater than the first wall thickness of the turbine housing.
An insert for a turbine housing, comprising:
- a sheet metal component including a valve seat for a wastegate valve and a bearing bush for mounting a wastegate shaft;
- and
- a valve disc mounting the valve seat, the valve disc having a profile matching the valve seat;
- wherein the sheet metal component has a wall thickness greater than a wall thickness of the turbine housing.
