ABSTRACT:
At the electromagnetically controlled wrap around spring clutch a braking spring (14) designed as a wrap around spring is foreseen on the driven shaft (4) in addition to the clutch spring (8) acting between the driving shaft (3) and the driven shaft (4), which braking spring (14) is also switched by the control magnet (11), such that if the magnet is excited the driven shaft (4) is released, but at a currentless magnet the driven shaft (4) is immediately braked and blocked in the direction of the drive.
