Abstract
The invention has an assembly for identifying the direction of power in a driveline in the case of torque transmission. The assembly includes a positively driven first drive element and a second drive element connected to the first to pass on torque. The first and the second drive elements are rotatable relative to each other in a torque-free way, via a limited angle of rotation, but in their respective end positions, relative to each other, they rest against non-rotating stops. Furthermore, the assembly includes a switching pin and a sensor for recording the respective relative position of rotation of the second drive element relative to the first drive element. Also, the assembly includes toothed discs and associated sensors for recording the direction of rotation. The sensors load an evaluating unit which, as a function of the relative positions of rotation of the drive elements and the directions of rotation, generates a signal characterizing the direction of power.
