摘要： A lock-up device includes an input rotary member into which the torque is inputted and an output rotary member rotatable relatively to the input rotary member in a predetermined torsion angular range. The output rotary member outputs the torque. The lock-up device also includes a plurality of first coil springs coupling the input rotary member and the output rotary member. The plurality of first coil springs are actuated in an entirety of the torsion angular range. The lock-up device further includes a plurality of second coil spring pairs or sets on either an outer peripheral side or an inner peripheral side of the plurality of first coil springs so as to be actuated in parallel to the plurality of first coil springs. The two or more coil springs have different magnitudes of stiffness and are actuated in series.

摘要： A lock-up device includes a clutch part, an input plate, an output plate, torsion springs and an input plate support member. The clutch part is disposed between a front cover and a turbine, and is configured to allow or block transmission of a torque. The input plate is coupled to a clutch output member of the clutch part. The output plate is fixed to a turbine shell. The torsion springs are disposed between the input plate and the output plate, and absorb and attenuate a torsional vibration. The input plate support member is fixed to a front cover side of a turbine shell and positions the input plate in a radial direction and an axial direction.

摘要： A lock-up device is disposed between a front cover and a turbine in a torque converter to mechanically connect the front cover and the turbine. The lock-up device includes a clutch part and a release part. The clutch part is disposed in a power transmission path from the front cover to the turbine and is configured to be in a clutch-on state of transmitting a power from the front cover to the turbine in a set posture. The release part is configured to be actuated by a hydraulic pressure being increased in a space on a turbine-side of the piston to turn the clutch part from the clutch-on state to a clutch-off state and to block transmission of the power from the front cover to the turbine.

摘要： A lock-up device having multistage torsional characteristics includes a retaining plate, a driven plate, a plurality of pairs of outer peripheral side torsion springs configured to elastically couple the both plates, a support plate and a plurality of inner peripheral side torsion springs. The support plate is rotatable relative to the retaining plate and the driven plate, and causes the outer peripheral side coil springs in each pair to act in a series-like manner. Each inner peripheral side torsion spring has a length shorter than that of each outer peripheral side torsion spring. Additionally, the support plate is configured to be restricted from rotating relative to the driven plate when stopper parts of the support plate contact intermediate stopper parts of the driven plate.

摘要： A stator support structure supports a stator of a torque converter on a stationary shaft, and includes an inner race and an annular one-way plate. The inner race is coupled to the stationary shaft to be non-rotatable relative thereto, and has a plurality of protrusions on the outer peripheral surface thereof. The annular one-way plate is mounted to the inner peripheral surface of the stator to be non-rotatable relative thereto, and has a plurality of pawls. The pawls are configured to prevent relative rotation between the stator and the inner race by making contact with first end surfaces formed as one rotation-directional end surfaces of the plural protrusions when the stator is rotated in a first direction. The pawls are configured to allow relative rotation between the stator and the inner race by elastically deforming in a radial direction to climb over the protrusions when the stator is rotated in a second direction.
