20120077604 | TORQUE FLUCTUATION ABSORBER - A torque fluctuation absorber includes a first damper portion absorbing torque fluctuations caused by a torsion between a first rotary member and a second rotary member, a second damper portion absorbing torque fluctuations caused by a torsion between the second rotary member and a third rotary member, and a stopper portion. The first rotary member includes a first projecting portion projecting radially inwardly and being contactable with the stopper portion by the torsion between the first rotary member and the second rotary member. The third rotary member includes a second projecting portion projecting radially outwardly and being contactable with the stopper portion by the torsion between the third rotary member and the second rotary member. The second projecting portion makes contact with the stopper portion at a radially inner side relative to a portion where the first projecting portion makes contact with the stopper portion. | 03-29-2012 |
20120234642 | TORQUE FLUCTUATION ABSORBER - A torque fluctuation absorber includes a damper portion absorbing a torque fluctuation between the output shaft and the input shaft with an elasticity thereof, and a limiter portion arranged on the power transmission path from the damper portion to the input shaft, configured to slip when the torque fluctuation by a torsion between the output shaft and the input shaft equals or exceeds a predetermined torque defined to absorb at the damper portion. The damper portion includes a center plate transmitting a rotational power to the limiter portion, side plates receiving the input of the rotational power from the output shaft, an elastic member absorbing the torque fluctuation caused by the torsion between the center plate and the side plates. The side plates directly or indirectly connect to a flywheel that connects to the output shaft at a circumferential portion outward in a radial direction relative to the damper portion. | 09-20-2012 |
20120242017 | TORQUE FLUCTUATION ABSORBING APPARATUS - To provide a torque fluctuation absorbing apparatus capable of achieving cost reduction. The fluctuation absorbing apparatus includes a first plate secured to a flywheel; a second plate disposed at a distance from the first plate; a third plate slidably sandwiched between the first plate and the second plate; and a resilient section that is supported by, fixed to or integrated with the first plate or the second plate and biases the second plate toward the first plate. | 09-27-2012 |
20120298472 | TORQUE FLUCTUATION ABSORBING APPARATUS - A torque fluctuation absorbing apparatus includes a first side plate, a second side plate, a lining plate disposed between the side plates, a connecting member that connects the side plates at a position that is radially inward relative to the lining plate, a pressure plate disposed between the second side plate and the lining plate, and an elastic member that biases the pressure plate toward the lining plate. The lining plate is slidably sandwiched between the first side plate and the pressure plate, and the first and second side plate each includes a reinforcing portion that includes a portion that is axially curved at a location that is radially outward relative to the connecting member. | 11-29-2012 |
20120302359 | TORQUE FLUCTUATION ABSORBING APPARATUS - A torque fluctuation absorbing apparatus that includes a first assembly that absorbs a fluctuating torque generated between a first rotating shaft and a second rotating shaft that are arranged coaxially, a first end of the first assembly being connected to the first rotating shaft from the second rotating shaft side by a first connecting member, a second assembly that absorbs a fluctuating torque generated between the first rotating shaft and the second rotating shaft, the second assembly being disposed more toward the second rotating shaft side than the first connecting member and a second end thereof being connected to the second rotating shaft, and a second connecting member that connects a second end of the first assembly to a first end of the second assembly. | 11-29-2012 |
20130029771 | TORQUE FLUCTUATION ABSORBER - A torque fluctuation absorber includes a first plate member being rotatable, a second plate member positioned to be axially separated from the first plate member, the second plate member being rotatable relative to the first plate member, a first friction member arranged between the first plate member and the second plate member and slidably pressed against the first plate member and the second plate member, and a first guide portion restricting the first friction member from moving radially inwardly. | 01-31-2013 |
20130298725 | TORQUE FLUCTUATION ABSORBING APPARATUS - A torque fluctuation absorbing apparatus comprises a first plate member, a second plate member disposed at a position axially offset from the first plate member, an intermediate plate member that is disposed between the first plate member and the second plate member and has a frictional sliding surface mating with the second plate member, rolling elements disposed so as to roll between the intermediate plate member and the first plate member, and resilient member that allows the intermediate plate member and the first plate member to rotate relative to each other. The intermediate plate member and the first plate member have acting sections on a surface whereon at least one of the rolling elements rolls, the acting sections press the intermediate plate member against the second plate member by a relative rotation between the intermediate plate member and the first plate member. | 11-14-2013 |
20140323232 | DAMPER DEVICE - A damper device includes: a pair of first plates axially separated from each other along a rotation axis and rotatable integrally with each other around the axis in a state where the first plates intersect the axis; a second plate including a portion positioned between the first plates, having an opening, and rotatable around the axis in a state where the second plate intersects the axis; an elastic member between the first and second plates, and elastically deformed a circumferential direction of the axis; and a third plate having a first portion positioned on an inner side of the opening and coupled to the first plates in a state where the first portion is between the first plates, and a second portion positioned on an outer side of the opening, and rotatable around the axis in a state where the third plate intersects the axis. | 10-30-2014 |
