UNIT CLUTCH / BRAKE WITH ENVELOPING SPRINGS WITH ADJUSTMENT OF THE DIFFERENCE BETWEEN THE SPRINGS.

摘要

The invention relates to a clutch / brake unit comprising rotary input and output hubs, fixed means in rotation of a brake, a clutch spring telescoped on the input and output hubs and coupling them when it is contracted, a telescoped brake spring on the output hubs and brake and coupling when it is contracted. BR/ According to the invention, the tails of the clutch (25) and brake (37) springs are connected to separate sleeves which form the control collar (30) of the unit; the sleeves (40) and (50) are normally coupled for unison rotation by an internally splined collar (45) which can be slid into a released position which allows relative rotation of the sleeves to adjust the torsional difference between the springs. BR/ The invention applies in particular to training. / P
