A gear set arrangement () for a bicycle gearbox () includes a planetary assembly, a stationary component (), a first and a second brake (B, B), and a first and a second freewheel clutch (F, F). One planetary gear set () of the planetary assembly includes a first rotary element, a second rotary element, and a third rotary element. The first rotary element is rotationally fixable on the stationary component () by the first brake (B). The first rotary element is connectable to the output () by the first freewheel clutch (F). The second rotary element is rotationally fixable on the stationary component () by the second brake (B). The second rotary element is connectable to the output () by the second freewheel clutch (F). The third rotary element is connected to the input () for conjoint rotation. The gear set arrangement () is configured to provide three ratios.

A method of determining at least one of a rotational angle position and a rotational speed of a rotating element of a drive train includes arranging at least two sensors in an offset manner in a circumferential direction of the rotating element, recording a measured value indicative of a characteristic of a rotation of the rotating element with each sensor, and determining at least one of a rotational angle position and a rotational speed with reference to the measured values and a distance between the at least two sensors in the circumferential direction.

Method for determining a rotational angle position and/or a rotational speed

A method for damping torsional oscillations in a drive train component, in particular a gearbox, in particular in a power production plant, includes adjusting a load on the output side in the drive train as a function of a difference between a rotational speed of an input shaft of the drive train component and a rotational speed of an output shaft of the drive train component.
