A hybrid assembly, including: a torque converter; a shaft; a hybrid module; and a module hub. The torque converter includes: a cover; an impeller; a turbine; a stator; and an output hub arranged to non-rotatably connect to a transmission input shaft. The shaft is arranged to receive torque and includes a channel. The hybrid module includes: an electric motor including a stator and a rotor non-rotatably connected to the cover; and a transfer clutch arranged to control transmission of the torque from the shaft to the cover. The hub is non-rotatably connected to the cover and includes a channel: connected to the torque converter; and arranged to receive first pressurized fluid from a first channel in the transmission input shaft. The channel of the shaft is arranged to receive second pressurized fluid, from a second channel in the transmission input shaft, to control operation of the transfer clutch.

A dynamic vibration absorber is disclosed. The dynamic vibration absorber includes a rotatable first hub, an inertia member, a plurality of elastic members, a plurality of sliders, and a guide member. The inertia member is disposed on an outer peripheral side of the first hub. The inertia member is rotatable relative to the first hub. The plurality of elastic members radially extend between the first hub and the inertia member. The plurality of elastic members are elastically deformable and elastically couple the first hub and the inertia member in a rotational direction. The plurality of sliders are radially movable along the plurality of elastic members. The plurality of sliders are configured to contact the plurality of elastic members. The guide member radially move the plurality of sliders. The guide member determines radial positions of the plurality of sliders.

A front cover assembly is disclosed. The front cover assembly includes a front cover body having a disc shape and a hub having a tubular shape. The front cover body includes a tubular portion in a center part thereof. The tubular portion is closed at one end thereof. The hub includes an engaging portion integrated with at least part of an outer peripheral surface thereof. The hub includes a coupling portion configured to extract power on an inner peripheral surface thereof. The engaging portion is press-fitted to the tubular portion of the front cover body.

A backing plate assembly includes a front cover and a rear cover. The front cover defines an inner surface and a front plane, and the rear cover terminates at a lip. A backing plate forms a body having an outer surface that terminates at a base portion. When the outer surface is coupled to the inner surface, the backing plate is rotationally but not axially coupled to the front cover. The lip contacts the base portion to define a maximum axial distance between the backing plate and the front plane.

A viscosity-torsional vibration damper or absorber for a crankshaft of a combustion engine includes an annular damping or absorbing arrangement which can be fastened to the crankshaft. The damping or absorbing arrangement is fastened in an outer diameter region to a holding device which, on the other hand, can be fastened to the crankshaft and can be sprung in the axial direction of the crankshaft, but is inherently rigid radially with respect to the crankshaft.

The present invention relates to a lock-up device for a torque converter which has a simple structure compared to the prior art, which reduces manufacturing costs, and which may reduce a size of the entire torque converter and improve a damping ability of the dynamic damper by minimizing an installation space of a dynamic damper.

A torque converter assembly that has a turbine assembly, a pump assembly, and a clutch assembly that selectively rotationally couples the turbine assembly to the pump assembly. The clutch assembly also has at least one clutch disk and a backing plate assembly defining a backing plate surface and formed by a first plate and a second plate coupled to one another. The first plate and the second plate are coupled to each other at a first radius and a second radius, the second radius being substantially adjacent to the backing plate surface.

A side plate utilized in a torque converter, comprising a first annular surface, a second annular surface opposite the first annular surface, an outer race defining an outer peripheral of the first and second annular surface, an inner race defining an inner peripheral of the first and second annular surface, and a neck extending axially away from the second annular surface and located along the inner race.

A hybrid module configured for arrangement in the torque path upstream from a transmission and downstream from an internal combustion engine includes an electric motor including a stator and a rotor rotatable within the stator, and a torque converter including a cover, an impeller and a turbine. The cover includes a pump drive configured for driving a fluid pump of the transmission. The torque converter includes a bypass clutch configured for frictionally drivingly connecting the cover to the impeller in an engaged orientation and for frictionally drivingly disconnecting the cover from the impeller in a disengaged orientation, the cover being non-rotatably fixed to rotor. The hybrid module also includes a connect/disconnect clutch having a clutch output non-rotatably fixed to the rotor. The connect/disconnect clutch is configured for being actuated between an engaged orientation for drivingly connecting the internal combustion engine to the cover of the torque converter and a disengaged orientation for drivingly disconnecting the internal combustion engine from the cover of the torque converter. The hybrid module is configured for transmitting torque from the internal combustion engine to the pump drive without driving the impeller when the connect/disconnect clutch is in the engaged orientation and the bypass clutch is in the disengaged orientation.
