摘要： A drive device includes a fluid coupling and a rotary electrical machine. The fluid coupling is configured such that a torque is inputted thereto from a first side in an axial direction and is outputted therefrom to a second side in the axial direction. The rotary electrical machine includes a first stator and a rotor. The first stator is disposed in a non-rotatable manner. The rotor is disposed to be rotated about a rotational axis of the fluid coupling. The rotary electrical machine is disposed on the second side with respect to the fluid coupling in the axial direction. The rotary electrical machine overlaps the fluid coupling in an axial view.

摘要： A hydraulic power transmission device includes a front cover, a torque converter main body, a lock-up device, and a dynamic damper. The dynamic damper has a base plate, inertia rings and lid members that configure an inertial body, viscosity attenuation portions, and an elastic coupling portion. The base plate is fixed to an output plate. The inertial body can move in the rotation direction relative to the base plate. The viscosity attenuation portions can generate a variable hysteresis torque according to the relative speed difference between the base plate and the inertial body.

摘要： The power transmission device transmits power from an engine to a transmission and includes an input-side rotary member, an output-side rotary member, a first elastic member, a float member and a damper device. The input-side rotary member receives the power inputted thereto from the engine. The output-side rotary member outputs the power to the transmission. The first elastic member couples the input-side rotary member and the output-side rotary member to enable relative rotation therebetween. The float member is rotatable relative to the input-side rotary member, the output-side rotary member and the first elastic member and is configured to slide against the first elastic member when rotated. The damper device is mounted to the float member and includes an inertia member that is rotatable relative to the float member.

摘要： The present device includes a mass body, a centrifugal element and a plurality of conversion mechanisms. The mass body is disposed to be rotatable with the rotor and be rotatable relative to the rotor. The centrifugal element is disposed to receive a centrifugal force to be generated by rotation of at least one of the rotor and the mass body. Each of the plurality of conversion mechanisms is configured to convert the centrifugal force into a circumferential force when a relative displacement is produced between the rotor and the mass body in a rotational direction. The circumferential force is directed to reduce the relative displacement. The respective plurality of conversion mechanisms are disposed at intervals in a circumferential direction.

摘要： A torque fluctuation inhibiting device includes a first rotating body, a second rotating body, a centrifugal element, a support portion, and a displacement inhibiting mechanism. Torque is input to the first rotating body. The centrifugal element is subject to centrifugal force due to rotation of the first rotating body and moves in a direction different from a direction in which the centrifugal force acts. The support portion is provided in the first rotating body or the second rotating body and moveably guides the centrifugal element in the direction different from the direction in which the centrifugal force acts on the centrifugal element. The displacement inhibiting mechanism generates circumferential force which reduces a relative displacement of the first rotating body and the second rotating body when the centrifugal element moves in the direction different from the direction in which the centrifugal force acts on the centrifugal element.
