ABSTRACT:
A driving gear having external teeth in mesh with internal teeth of a sliding sleeve, adapted to be axially shifted into meshing engagement with external teeth of a driven gear coaxially adjoining the driving gear, carries several peripherally spaced rockers which project radially into axially extending inner peripheral guide grooves of the sleeve. A synchro ring coaxial with the two gears is rotationally entrained by the driving gear, through the intermediary of the rockers thereof, and has a clutch surface confronting a similar surface of the driven gear across a narrow clearance which closes when the ring, under an axial thrust from the rockers in response to an incipient coupling shift of the sleeve, is moved toward the driven gear. As long as a speed difference exists between the two gears, the synchro ring exerts upon the rockers a peripheral force which urges them into lateral pockets of the respective guide grooves so as to prevent a completion of the coupling shift until synchronism has been established. The driven gear and the synchro ring may be duplicated on opposite sides of the driving gear and the sleeve.
