Patent ID: 10502270

Abstract:
A power transmitting system including: a first piston disposed within a center bore formed through the rotary shaft such that the first piston is axially reciprocable; a sleeve connected to the first piston and having internal teeth meshing with the external teeth of the rotary shaft so that the sleeve is rotated with the rotary shaft, and such that the sleeve is axially reciprocable together with the first piston according to axial movements of the first piston; a synchronizer ring supported in sliding contact with an outer circumferential tapered surface of the clutch gear such that the synchronizer ring is rotatable relative to the clutch gear; and an actuator including a second piston to axially advance the first piston for thereby bringing the sleeve's internal teeth into meshing engagement with the clutch gear through the synchronizer ring. The first piston and second piston are disposed coaxially with the rotary shaft.
