An assembly for sensing the angular position of a rotatable shaft includes a bearing ring, a driving gear, and a measuring gear. The bearing ring is connectable to the shaft and has two recesses. The driving gear is rotatable about a rotational axis and has two entraining elements. The entraining elements extend radially toward the rotational axis of the driving gear and are arranged opposite one another with respect to the circumference of the driving gear. The entraining elements respectively penetrate into the recesses of the bearing ring such that the driving gear is connected to the bearing ring and rotates as the bearing ring rotates. The measuring gear is rotatable about a rotational axis and is engaged with the driving gear such that the measuring gear rotates as the driving gear rotates. One of the entraining elements is resilient.

Angle sensor

An angle sensor includes two measuring pinions which rotate in the same direction in response to a drive pinion rotating. The measuring pinions have different absolute angular positions after rotating. The absolute angular position of the drive pinion is determinable from the absolute angular positions of the measuring pinions. A delta wheel between the measuring pinions has two coaxially arranged rings. One ring engages the second measuring pinion and the other ring engages the first measuring pinion such that the rings rotate relative to one another in the same direction in response to the measuring pinions rotating in the opposite direction. A spring connecting the rings together biases the rings to move in opposite directions toward one another after the rings have been rotated relative to one another in the same direction such that the rings respectively press the measuring pinions against the drive pinion.
