Synchronizer clutch assembly

摘要

A synchronizer clutch assembly incorporates spline teeth on both a sleeve and a ratio gear. The sleeve is slidably disposed on a hub which is rotatably secured to a shaft member. The sleeve is moved longitudinally so that the spline teeth thereon intermesh with the spline teeth on the ratio gear to provide a drive connection therebetween. The spline teeth on the sleeve have a locking angle portion to prevent the inadvertent disengagement of the spline teeth and a flat portion to prevent fore and aft movement of the ratio gear from being transmitted via the spline teeth to the sleeve.
