Methods of repairing a torque converter that enable the continued use of a torque converter and result in a repaired torque converter with a higher-strength and more durable construction. In some examples, a backing ring can be replaced with a replacement backing ring that includes a spline ring for replacing the function of a cover spline ring. In some examples, a method of repairing a torque converter can be improved by providing a replacement backing ring with a radial protrusion for locating the backing ring on the cover, and a method of determining an axial location of the radial protrusion.

A rotary device includes a first rotor, a second rotor, a centrifugal element, and a first rolling member. The first rotor includes an accommodation portion having first and second guide surfaces. The first and second guide surfaces face both sides in a circumferential direction. The first rotor is disposed to be rotatable. The second rotor is disposed to be rotatable with and relative to the first rotor. The centrifugal element is disposed within the accommodation portion. The centrifugal element is disposed to be radially movable by a centrifugal force acting thereon in rotation of the first or second rotor. The centrifugal element rotates about a rotational axis thereof in radial movement thereof. The first rolling member is disposed between the first guide surface and the centrifugal element. The first rolling member rolls on the first guide surface in accordance with rotation of the centrifugal element about the rotational axis thereof.

A hybrid module configured for arrangement in a torque path upstream from a transmission and downstream from an internal combustion engine includes an electric motor including a rotor and a stator for driving the rotor, a torque converter downstream of the electric motor, and a rotor input clutch selectively engageable and disengageable to drivingly connect the rotor to or disconnect the rotor from an output of an engine crankshaft. The rotor input clutch includes a piston and at least one clutch plate. The piston is configured for being pressed in a first axial direction into the at least one clutch plate to engage the rotor input clutch via a pressure increase of fluid in an apply chamber. The hybrid module also includes a compensation chamber assembly. The compensation chamber assembly and the piston define a compensation chamber radially offset from the apply chamber. The compensation chamber assembly is configured for applying a force on the piston in a second axial direction opposite the first axial direction via a pressure increase of fluid in the compensation chamber.

A torque converter includes a front cover arranged to receive a torque and a damper assembly including an output flange arranged to non-rotatably connect to a transmission input shaft. The torque converter further includes a seal plate disposed between the front cover and the output flange. The seal plate is non-rotatably connected to the cover. The torque converter further includes a thrust washer including a body axially disposed between the seal plate and the output flange. The thrust washer is fixed to the seal plate.

A power transmission device includes an electric motor, and a torque converter connected to the electric motor to transmit torque. A torque converter characteristic line is determined based on a capacity coefficient of the torque converter and indicates torque of the torque converter relative to each rotational speed of the torque converter. An electric motor characteristic line indicates a maximum output torque of the electric motor relative to each rotational speed of the electric motor. A first range corresponds to a range equal to and greater than a base rotational speed of the electric motor and equal to or less than a first average rotational speed, which is an average of the base rotational speed and a maximum rotational speed of the electric motor. The capacity coefficient is such that the characteristic line for the torque converter intersects the characteristic line for the electric motor in the first range.
