Abstract: A harmonic pin ring gear system comprises an input shaft, an output shaft, two outer gears each with internal toothing and a single inner gear with external toothing. The inner gear is arranged concentrically to a first outer gear and in axial direction inside the first outer gear. A drive means extends between the two outer gears and the inner gear and comprises a pin-retaining ring formed as one part in circumferential direction and a multiplicity of pins that protrude laterally in axial direction from the pin-retaining ring. A rotary transmitter lifts the drive means off the external toothing of the inner gear and presses the drive means into the internal toothing of the outer gears.

Abstract: A gear has an input shaft and an output shaft, the gear includes the following elements: an outer wheel; an inner wheel which is positioned concentrically in relation to the outer wheel; a traction means extending between the outer wheel and the inner wheel; and a revolving transmitter which lifts the traction means from an outer periphery of the inner wheel and pushes the traction means onto an inner periphery of the outer wheel, the transmitter includes a first transmitter element and a second transmitter element provided on a rotatable transmitter carrier, wherein the first transmitter element and the second transmitter element are rotatable on the transmitter carrier and wherein each transmitter element is provided eccentrically from a rotation axis of the transmitter carrier, the first transmitter element includes a first disk, and the second transmitter element includes a second disk.

Abstract: A method for the operation of an electrical circuit taking the form of a multi-level half-bridge (MLHB), and a multi-level half-bridge designed for implementation of the method, comprising two connections to which a bridge voltage is applied and which are connected via two symmetrical branches meeting at a central connection, wherein a central voltage is applied to the central connection against the potential of one of the connections.

Abstract: A vehicle has a motor-gear unit, a trailing wheel of the vehicle being connected the output shaft of the gear and an input shaft of the gear being connected to a motor. The gear has an outer wheel, an inner wheel and a traction means extending between the outer wheel and the inner wheel.
