20090005205 | Power transmission device - A power transmission device is provided to transmit power from an engine to a transmission, including a transmission mechanism, a first clutch, a second clutch, a damper mechanism, and a casing. The transmission mechanism is configured to transmit power with two kinds of rotational speeds that vary in stages. The first clutch is configured to switch rotational speed in the transmission mechanism to decrease the speed ratio. The second clutch is configured to set the rotational speed ratio of the transmission mechanism so that output rotational speed equals input rotational speed, that is, the transmission mechanism is in a fixed state. | 01-01-2009 |
20120255826 | CLUTCH DEVICE - A clutch device includes an input rotor, a rotation support mechanism, a first pressure plate, a second pressure plate, a first clutch disc assembly and a second clutch disc assembly. The input rotor includes a first disc portion and a second disc portion disposed away from the first disc portion at a predetermined space. The rotation support mechanism supports the input rotor for allowing the input rotor to be rotated with respect to a first input shaft and a second input shaft. | 10-11-2012 |
20130310218 | TORQUE TRANSMISSION DEVICE - It is an object of the present invention to provide a compact torque transmission device. The torque transmission device includes an input-side member, an output-side member, a clutch and a pressing mechanism. The clutch is configured to transmit or cut torque between the input-side member and the output-side member. The pressing mechanism includes a pressing member for pressing the clutch, and a pressing device. The pressing device is a device for pressing the pressing member, and is disposed on the inner peripheral side of the clutch. | 11-21-2013 |
20140318916 | CLUTCH DEVICE - A clutch device includes an input rotor, a first clutch, a second clutch, a first drive mechanism and a second drive mechanism. A first clutch is disposed switchably between a first transmitting state of transmitting power and a first blocking state of blocking power transmission. A second clutch is disposed switchably between a second transmitting state of transmitting power and a second blocking state of blocking power transmission. The first drive mechanism includes a first drive support member and the second drive mechanism includes a second drive support member. A drive clearance is configured to be produced axially between the first drive support member and the second drive support member in the first blocking state and the second blocking state. The drive clearance is less than a sum of the first stroke and the second stroke. | 10-30-2014 |
20140318917 | CLUTCH DEVICE - A clutch disc assembly includes an annular friction part, an input member, an output member and an elastic member. The input member includes a fixation plate, a fixation member and a holding plate. The fixation plate has at least a fixation hole. The fixation hole axially penetrates through the fixation plate. The fixation member is inserted into the fixation hole. The fixation member fixes the friction part to the fixation plate. The holding plate has at least a spare hole. The spare hole axially penetrates through the holding plate. The holding plate holds the elastic member in an elastically deformable state together with the fixation plate. The spare hole is disposed in a radial position substantially the same as a radial position of the fixation hole. | 10-30-2014 |
