TRANSMISSION DEVICE FOR AUXILIARY OR ACCESSORY OF VARIABLE SPEED MOTOR, ENGINE THUS EQUIPPED AND APPLICATIONS

摘要

P The transmission device (12) is installed between a supercharger (7) and a pulley (11) for driving it from the vehicle engine. The device comprises two successive modules (16, 46) each capable of a direct drive ratio by a freewheel (31, 61), or an overdrive ratio by locking the sun gear (21, 51) by means of a clutch (26, 56) clamped by a spring (28) or loosened by the action of centrifugal weights (32, 62) whose action is more than compensated by the axial thrust of FP teeth produced by the sun wheel (21, 51) when under load. Use to autonomously ensure a regularization of the speed of rotation of the device (7) despite the speed fluctuations of the pulley (11). / P
