TRANSMISSION MECHANISM COMPRISING A CLUTCH AND A MULTIPLE-RATIO GEAR-BOX

摘要

The mechanism comprises a clutch and a gear box having a plurality of speed ratios disposed between a motor and receiving means. Means are provided for acting on the speed of the motor so as to bring the input element and the output element of the clutch to substantially the same speed before the engagement of the clutch. The mechanism further comprises in combination a detector of the speed of the motor, a detector of the speed of the receiving means, a numeric calculator of the theoretical speed of one of these components as a function of the speed of the other component and of the engaged speed ratio of the gear box, and a comparator of the calculated speed and the measured speed which has its output connected to the means for acting on the speed of the motor.
