摘要： The disclosure relates to a method for producing a component, in particular a vehicle component or an engine component, such as a piston of an internal combustion engine. The method comprises forming a first body region, in particular by means of casting or forging. The method includes forming a second body region, which is connected to the first body region, from an aluminium alloy or an iron-based alloy or a copper-based alloy by means of an additive manufacturing method. The second body region is alloyed in such a manner that it has higher thermal stability, higher mechanical strength or higher wear resistance upon tribological stressing than the first body region.

摘要： An axle drive system for a motor vehicle, in particular a commercial vehicle, has a drive unit. The axle drive apparatus also has a first drive axle for drive-connecting to the drive unit. The first drive axle has a first intermediate gear stage and a first bevel gear stage. The axle drive system also has a second drive axle which is drive-connected to the first drive axle. A transmission ratio of the first intermediate gear stage is not equal to 1. A transmission ratio of the first drive axle, in particular a common transmission ratio of the first intermediate gear stage and the first bevel gear stage, corresponds to a transmission ratio of the second drive axle.

摘要： A piston for an internal combustion engine, such as a high-pressure direct injection (HPDI) diesel/gas internal combustion engine. The piston has a piston recess, in particular an omega piston recess. The piston has a piston crown face which is provided so as to extend annularly about a centre axis (M) of the piston. The piston has a plurality of piston stages, which are provided so as to extend annularly about the centre axis (M) and which are arranged between the piston crown face and the piston recess. The piston geometry can lead to an increase of the degree of engine efficiency with a simultaneous reduction of the exhaust emissions.

摘要： The present disclosure relates to a device for folding in a camera on a motor vehicle in order to protect the device in the event of a collision with an obstacle. The device has a first housing element, in which the camera is received. The device has a second housing element, which is constructed to be connected to the motor vehicle in a positionally fixed manner. The first housing element and the second housing element are pivotably connected to each other by means of a first pivot connection, which defines a first rotation axis, and a second pivot connection, which defines a second rotation axis which is spaced apart from the first rotation axis.

摘要： A traction energy storage system including multiple electrical energy stores and a system controller. Each of the energy stores includes one or more cell modules electrically connected via busbars, an energy store high-voltage interface connectable to the busbars and an energy store controller controlling the cell modules. Each of the cell modules comprises multiple storage cells and a cell module controller. Each of the cell module controllers is configured to output measured values relating to the storage cells in the respective cell module to the energy store controller. Each of the energy store controllers is configured to take the measured values obtained as a basis for generating signals having electrical characteristic quantities of the respective energy store and at least one limit value for a current through the energy store high-voltage interface of the respective energy store.

摘要： An internal combustion engine is described. The internal combustion engine comprises a valve control which is configured to close inlet valves of the internal combustion engine at Miller or Atkinson closing times. An electrified exhaust-gas turbocharger of the internal combustion engine comprises an electric machine which is operable selectively as a motor or generator. A control unit operates the electric machine of the electrified exhaust-gas turbocharger as a motor in a first load range of the internal combustion engine and as a generator in a second load range which corresponds to greater loads of the internal combustion engine than the first load range.

摘要： A drivetrain module for a motor vehicle including a flywheel connectable to a crankshaft, and a crankshaft starter-generator which has a rotor. The flywheel has a multiplicity of fastening points. In a region of magnetically soft action of the rotor, a multiplicity of passage openings is arranged in each case so as to be spatially assigned to the fastening points of the flywheel. Through the passage openings, pin-like fastening elements interact with the respectively assigned fastening points for the rotationally conjoint connection of rotor and flywheel.

摘要： A switching arrangement for discharging an energy storage device of a motor vehicle including an energy storage device that stores electrical energy and supplies an electrical machine of a motor vehicle, a discharging circuit having a discharging resistor, a voltage comparison element and an activation switching device. The activation switching device starts discharging the energy storage device via the discharging resistor at the end of a delay period after the motor vehicle has been switched off. The voltage comparison element compares the prevailing voltage of an energy storage voltage and a voltage threshold value and terminates the procedure of discharging the energy storage device if the prevailing voltage of the energy storage device is less than or equal to the voltage threshold value.
