A high-efficiency CVT dry clutch

Abstract

The utility model provides a kind of CVT dry clutch of high efficiency dithering reduction, it is related to clutch technical field, the flanging bushing additionally provided in the original clutch basis can significantly reduce the wear between counterweight assembly, first side washer and second side washer and counterweight pin respectively, make counterweight assembly spin smoothly when fling, promote the smooth engagement of the combination of friction material and clutch outer sleeve, avoid the occurrence of stick-slip phenomenon and unstable problem of torque transmission (friction coefficient is stable), to further reduce the possible of dithering generation;In addition, disc spring is additionally provided, when clutch combination rotates, counterweight assembly does rotational motion along counterweight pin under the action of centrifugal force, at this time, disc spring exerts axial thrust on counterweight assembly, generates friction force on counterweight assembly under the action of friction coefficient, the friction force generated by disc spring can prevent counterweight assembly from reversing at this time, reduce the probability of unstable torque transmission, so as to reduce the possible of dithering generation.
