Abstract: A hybrid powertrain for a motor vehicle has an internal combustion engine and an electric machine that is connected to power electronics and to an electric energy storage device. The internal combustion engine is coupled to an internal combustion engine driveshaft and the rotor of the electric machine is coupled to an electric machine driveshaft that is connected to a planetary gear set with a sun gear, a planet carrier, and a ring gear, one element of which functions as an input element and another as an output element. The rotor of the electric machine can be selectively connected either to the input element or to the output element of the planetary gear set by way of a shiftable clutch).

Abstract: A running gear toothing for gearwheels and a process for producing such running gear is provided. In order to be able to work complex shapes (e.g. reinforcing ribs) into running gear, a preforged or precast gearwheels are produced oversized, and are then finished using an electrochemical erosion process. The invention eliminates complex machining operations and permits gear teeth finishing in highly spaced-constrained applications, thereby eliminating the need for production and assembly complex multi-component gears.

Abstract: In a gearwheel pairing, in which one of a pair of gearwheels has, at least at one side thereof a lid-shaped stop structure for engaging the other gearwheel for retaining it in engagement with the other gear wheel. The arrangement is expediently used in a differential transmission in particular a crown-wheel differential transmission.
