20140262676 | DRIVING FORCE TRANSMITTING APPARATUS - A driving force transmitting apparatus includes a rotating shaft, a frictional engagement device, a piston member, a piston housing, a piston chamber, an oil pressure sensor, an attachment hole, an operating-oil receiving chamber, a bubble removing chamber, and a bubble discharging groove. The rotating shaft has an axial direction and is rotatable around the axial direction. The frictional engagement device includes a frictional engagement unit which is disposed around the rotating shaft and which includes first and second friction members that are alternately stacked in the axial direction. The piston member is movable in the axial direction to press the frictional engagement unit so that the first and second friction members are engaged with each other. The piston housing contains the piston member. The piston chamber is defined between an inner surface of the piston housing and the piston member. | 09-18-2014 |
20140284168 | LUBRICATION STRUCTURE OF DRIVING FORCE TRANSMISSION APPARATUS - A lubrication structure of a driving force transmission apparatus includes a rotating shaft, a friction engagement device, a piston member, a piston housing, a component, a piston chamber, a moving member, a holding member, a rotation stopper, and a hydraulic oil path. The rotating shaft has a shaft direction and is rotatable around the shaft direction. The friction engagement device includes a friction engagement unit which is arranged around an outer circumference of the rotating shaft and in which a plurality of friction materials are alternately laminated along the shaft direction. The piston member is provided movably along the shaft direction to press the friction engagement unit so that the plurality of friction materials engage with each other. The piston housing houses the piston member. | 09-25-2014 |
