20100062864 | DAMPER DEVICE - A damper device includes a damper portion and a limiter portion, and the limiter portion has a first constitutive member formed to cover the damper portion or the limiter portion, a first and second friction materials fixed to a second constitutive member of the damper portion, a cover plate provided so as to be slidable to the first friction material, a support plate arranged so as to be distant from the cover plate at a radially inner portion of the support plate and so as to contact the cover plate at a radially outer portion of the support plate, a pressure plate provided so as to be slidable to the second friction material and a coned disc spring provided between the support plate and the pressure plate, wherein the first constitutive member is at least one of the cover plate and the support plate. | 03-11-2010 |
20100243404 | TORQUE FLUCTUATION ABSORBER - A torque fluctuation absorber includes: a first plate member, a second plate member, arranged axially with a predetermined distance from the first plate member, a third plate member which rotates integrally with the first plate member, and is arranged axially with a predetermined distance from the second plate member; slide members located between the second plate member and the third plate member; and an elastic member which is supported by the first plate member and biases the second plate member towards the plurality of slide members. The plurality of slide members are configured to generate a first hysteresis torque when a torsion angle between the second plate member and the third plate member is within a predetermined range, and to generate a second hysteresis torque greater than the first hysteresis torque when the torsion angle exceeds the predetermined range. | 09-30-2010 |
20110098119 | TORQUE FLUCTUATION ABSORBING APPARATUS - A torque fluctuation absorbing apparatus includes a first plate member, a second plate member rotatable relative to the first plate member, and a first friction member disposed between the first plate member and the second plate member and pressed against the first plate member in a slidable manner. The second plate member includes a first retaining surface that makes contact with the first friction member. The first friction member includes a plurality of grooves at a surface facing the first retaining surface of the second plate member, the grooves extending in a radial direction of the first friction member. | 04-28-2011 |
20110098120 | DAMPER DEVICE - A damper device includes a first side plate connected to a flywheel, to which a rotational force from a power source is transmitted, at an outer circumferential portion of the flywheel, a second side plate arranged at a position displaced in an axial direction relative to the first side plate and connected to the first side plate, a center plate member provided between the first side plate and the second side plate and outputting the rotational force towards a gear mechanism, and a spring member absorbing a torque fluctuation generated between the first side plate and the second side plate on the one hand and the center plate member on the other hand, wherein the center plate member is formed so that an outer diameter thereof is set to be greater than an outer diameter of each of the first side plate and the second side plate. | 04-28-2011 |
20120077606 | TORQUE FLUCTUATION ABSORBER - A torque fluctuation absorber includes a first rotary member formed into an annular shape and including a first protruding portion formed at an inner circumferential surface, a second rotary member connected to the first rotary member, a third rotary member including a second protruding portion formed at an outer circumferential surface, a damper portion absorbing torque fluctuations caused by torsion generated between the second rotary member and the third rotary member, and an elastic member arranged between the first protruding portion and the second protruding portion and absorbing a shock generated when the first protruding portion directly makes contact with the second protruding portion when the damper portion absorbs the torque fluctuations caused by the torsion generated between the second rotary member and the third rotary member. | 03-29-2012 |
20120252588 | TORQUE FLUCTUATION ABSORBER - A torque fluctuation absorber includes a first rotating member arranged to be rotatable, a second rotating member arranged in a rotatable manner relative to the first rotating member, a coil spring for buffering a torsion between the first rotating member and the second rotating member by means of an elastic force, and a cushion member arranged at an inside of the coil spring and buffering the torsion between the first rotating member and the second rotating member by means of an elastic force, wherein the cushion member includes an elastic member formed in a columnar shape, and an abrasion resistant member partly covering a side surface of the elastic member and including a greater abrasion resistance than an abrasion resistance of the elastic member. | 10-04-2012 |
