Abstract

A clutch 12 comprises a driving part and a driven part, a drag brake (58) being associated with an output shaft (40) of the driven part, the shaft being mounted for slight axial movement and being subjected to the action of a spring (68) which urges it in an axial direction, so that a shoulder (66) provided on it applies a friction washer (70) against a fixed shoulder (67), action means being provided for the controlled displacement of the said shaft in the opposite direction, so that the drag brake (58) is actuated only when the clutch is disengaged. <IMAGE>
