One aspect of the present disclosure relates to a power electronics device for an electrically-driven charging device for an engine, said power electronics device comprising one or more power electronics components which are designed to operate an electrically-driven charging device for an engine, first and second conductors for guiding current for the one or more power electronics components, and a choke for filtering electromagnetic interference. The choke has a magnetic core which forms a closed ring about the first and second conductors and comprises a tongue which extends, arising from the closed ring, between the first and second conductors.

Choke for electrically-driven charging devices

A supercharging device for an internal combustion engine, in particular for a vehicle, with a compressor having a compressor housing and having a compressor space in which a compressor wheel is arranged, an electric motor having a rotor and a stator, a motor housing having a motor space for accommodating the rotor and the stator, and a fluid-conducting connection from the compressor space into the motor space in order to permit pressure equalization between the compressor space and the motor space.

Supercharging device for a combustion engine

An exhaust-gas turbocharger () with a bearing housing (), a shaft () mounted in the bearing housing (), a compressor wheel () arranged on the shaft () and a turbine wheel () arranged on the shaft (), a housing component () which surrounds the compressor wheel () or the turbine wheel (), and a sealing ring () between the bearing housing () and the housing component (), wherein the sealing ring () is, in order to impart its sealing action, compressed in a direction perpendicular to the shaft ().

Exhaust-gas turbocharger

A bearing housing () of an exhaust-gas turbocharger, having a compressor-side housing flange (), a central housing section () which is integrally connected to the housing flange () and in which a first partial section () of an oil chamber () is arranged; and a turbine-side housing section () which has a turbine-side housing flange () and in which a second partial section () of the oil chamber () is formed. The central housing section () and the turbine-side housing section () are formed in one piece. A bearing housing () which forms a separate component is inserted into the central housing section () and into the turbine-side housing section (), with these delimiting the oil chamber ().

Bearing housing of an exhaust-gas turbocharger

A standard bearing unit () for different exhaust-gas turbocharger designs (), having a shaft (); having a shaft nut (); having sealing devices (); having a compressor wheel () which is arranged on a first end () of the shaft (); and having a turbine wheel () which is arranged on a second end () of the shaft (), wherein the shaft () is mounted in a standardized bearing sleeve () which has predefined, unchangeable outer dimensions () which are independent of the exhaust-gas turbocharger embodiment.

Standard bearing unit

An exhaust-gas turbocharger with a bearing housing which receives a static bearing bush for a rotor shaft. A lug supported in the bearing housing engages the bearing bush and prevents the bearing bush from rotating but avoids a restriction of the freedom of movement of the bearing bush in the axial and radial directions.

An exhaust-gas turbocharger () having a compressor (); a turbine (); and a bearing housing () which has a lubricant device () for shaft bearings (), which lubricant device can be connected via a lubricant feed line () to an engine lubricant circuit. A lubricant storage vessel () is connected between the lubricant feed line () and the lubricant device () of the bearing housing ().

A bearing housing () of an exhaust-gas turbocharger, having a housing body () in which an axial bearing () is arranged, and a compressor-side housing cover () which can be fixed in a compressor-side housing opening () via a fastening device (). The fastening device () is a non-positively locking fastening device.

A bearing housing () of an exhaust-gas turbocharger (), having a mounting bore (), a bearing device () which has two bearing bushes () arranged in the mounting bore (), between which bearing bushes is arranged a spacer (), and a rotational speed sensor () which is fixed in a bearing housing recess () and which engages into a sensor recess () of the spacer (). A resilient sleeve () is arranged in the bearing housing recess () around the rotational speed sensor () and engages with one end () into the sensor recess ().

An exhaust-gas turbocharger (), having a shaft () on which a compressor wheel () and a turbine wheel () are arranged, and a bearing housing () which has a turbine-side radial bearing bush () and which has an oil collecting chamber () arranged between the turbine-side radial bearing bush () and a turbine-side bearing housing end region (). The shaft () has a shoulder () which extends outward in the radial direction (R) into the oil collecting chamber () and, together with a radial-bearing-side first delimiting wall () of the oil collecting chamber (), delimits a gap ().

A bearing housing () of an exhaust-gas turbocharger, having a compressor-side housing flange (), a central housing section () which is integrally connected to the housing flange () and in which is arranged a first partial section () of an oil chamber () which has an oil inlet () and an oil outlet (), and a turbine-side housing section () which has a turbine-side housing flange () and in which is arranged a second partial section () of the oil chamber (). The central and turbine-side housing sections () are provided with an oil cooling duct ().
