Heat sink for an electric motor, in particular for a wheel hub drive of a commercial vehicle, with a channel which connects a first connection of the heat sink and a second connection of the heat sink, wherein the channel winds around the heat sink in a spiral. With such a heat sink, a flow condition of coolant within the channel can be generated in which secondary vortices are formed, and the cooling capacity is significantly improved.

In an electrical traction drive for a vehicle comprising at least two individual wheel drives that are to be controlled independently of each other, the drives are able to be operated redundantly in order for an emergency operating function to be implemented.

Electrical traction drive for a vehicle

A wheel hub drive as a direct drive of a wheel of a vehicle having an electric motor preferably designed as a permanent-magnet synchronous motor (PMSM)&#x2014;external rotor motor&#x2014;which is substantially arranged in the region within the wheel, wherein a rotating part of a friction brake is frictionally, interlockingly, and/or integrally connected to the motor for braking. The rotating part is operatively connected to the rotor of the motor, directly or indirectly, from outside of the motor.

A contact element for contacting a contact point formed on a body includes: an element section on the contact point side for a force-locking connection to the contact point, an element section on the connection side for connection to an electrical connection conductor, and an intermediate section which connects the two element sections to one another for compensating for thermal expansions. At least the element sections on the contact point side and on the connection side are made of different integrally bonded materials having material properties which are adapted to the functionality of the corresponding element section.

A turbine may include a turbine housing having an inlet opening and an outlet opening, and defining a housing interior space configured to be subjected to a through-flow of exhaust gas from an internal combustion engine. A turbine rotor may be rotatably mounted in the turbine housing about an axis of rotation defining an axial direction. An exhaust gas sensor may be arranged in a measurement space of the turbine housing the exhaust gas sensor configured to determine at least one part of a gas component of the exhaust gas carried in the turbine housing. A feed line may be arranged in the turbine housing having a feed opening and a discharge line arranged in the turbine housing having a discharge opening for feeding and discharging exhaust gas at least one of in and out of the measurement space.

Turbine for an internal combustion engine

A turbocharger for use in an internal combustion engine has at least one turbocharger housing, at least one compressor situated inside the turbocharger housing, and at least one turbine situated inside the turbocharger housing. In addition, the turbocharger has at least one sensor device for detecting at least a portion of a gas component of an exhaust gas of the internal combustion engine. The sensor device is at least partially integrated into the turbocharger housing.

The invention relates to a method for operating a sensor, in particular a sensor made of ceramic material. Said sensor is heated to a shock-resistance temperature which is higher than a specific temperature.

Method for operating a gas sensor

Exhaust-gas sensors that have a sensor element, which is surrounded by two protective tubes on a side facing the exhaust gas and which is additionally protected by a porous fiber package, are already known. The fiber package is disposed between the two protective tubes and is meant to protect the sensor element from thermal shock by water droplets hitting the sensor element. When the exhaust gas sensor is used as primary catalytic converter or raw emission sensor, the sensor element can get damaged by sulfur compounds contained in the exhaust gas. In the exhaust-gas sensor according to the invention, damage to the sensor element by exhaust-gas components contained in the exhaust gas is reliably prevented. According to the invention, the adsorption means is implemented in such a way that sulfur, phosphorus or silicon compounds are trapped irreversibly.
