車両用動力伝達装置
Document Type and Number:
Japanese Patent JP6627804
Kind Code:
B2
Abstract:
A vehicular power transmitting system (16) including a dog clutch (D1) having a synchro-mesh mechanism to selectively connect and disconnect a rotary shaft (44) having external teeth (44out), and a clutch gear (54) rotatable relative to the rotary shaft, to and from each other. The power transmitting system including: a first piston (90) disposed within a center bore (44a) formed through the rotary shaft (44) such that the first piston is axially reciprocable; a sleeve (56) connected to the first piston and having internal teeth (56s) 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 (78) supported in sliding contact with an outer circumferential tapered surface (54t) of the clutch gear such that the synchronizer ring is rotatable relative to the clutch gear; and an actuator (112) including a second piston (92; 200) to axially advance the first piston for thereby bringing the internal teeth of the sleeve into meshing engagement with the clutch gear through the synchronizer ring. The first piston and the second piston are disposed coaxially with the rotary shaft.
