INTEGRAL SHIFTING KEY FOR A SYNCHRONIZING TRANSMISSION

摘要

Change gear synchronizer according to present invention is characterized by axially shifting keys integrally connected together and located between outside of clutch hub and inside surface of clutch hub sleeve. Sleeve is connected to rotate with clutch hub but is arranged to shift axially relative thereto. Integral nature of shifting key assembly prevents individual keys from popping out from between clutch hub and clutch hub sleeve. Integral assembly of shifting keys urges synchronizer ring into frictional contact with rotating gear to thereby provide smooth synchronizing action between rotating gear and clutch hub.
