A torque converter includes a case and a bypass clutch having a plate rotationally fixed to the case and a friction disk having a friction material configured to engage with the plate to rotationally couple the friction disk to the plate when the bypass clutch is engaged. The friction disk includes a first circumferential connection surface having a plurality of alternating convex and concave arcuate segments. A drive plate includes a second circumferential connection surface having a plurality of alternating convex and concave arcuate segments. The first and second connection surfaces are in meshing engagement with the convex segments of the friction disk meshing with the concave segments of the drive plate and with the concave segments of the friction disk meshing with the convex segments of the drive plate.

A clutch disc includes a core plate and a friction member having an annular shape. The core plate includes a coupling portion having an annular shape and a plurality of fixation portions. The plurality of fixation portions protrude radially outward from the coupling portion and are circumferentially aligned through a plurality of slits each radially extending between adjacent two of the plurality of fixation portions. The friction member is fixed to the plurality of fixation portions and has an inner diameter larger than a diameter of the core plate at inner peripheral ends of the plurality of slits. The friction member includes a plurality of discharge grooves on an inner peripheral end surface thereof in corresponding portions thereof to the plurality of fixation portions. The plurality of discharge grooves lead water to the plurality of slits when the water drops on the inner peripheral end surface of the friction member.

A motor for driving a fan in a heating and/or cooling system includes a motor body, a motor cover, and an isolator. The isolator damps vibrations passed from the motor body to the motor cover. The isolator includes two isolating elements connected by a bridge. At least one of the two isolating elements includes at least two corners in a cross-sectional view.

The present damper device includes a large hysteresis mechanism, generating a large hysteresis torque, and a hysteresis inhibiting mechanism. In a positive-side torsional region, when relative rotation is performed until reaching a maximum torsion angle from a neutral position, the hysteresis inhibiting mechanism deactivates the large hysteresis mechanism until the relative rotation reaches a first torsion angle from the neutral position, but activates the large hysteresis mechanism until the relative rotation reaches the maximum torsion angle from the first torsion angle; and when the relative rotation is performed until reaching the neutral position from the maximum torsion angle, the hysteresis inhibiting mechanism deactivates the large hysteresis mechanism until the relative rotation reaches a second torsion angle less than the first torsion angle from the maximum torsion angle, but activates the large hysteresis mechanism until the relative rotation reaches the neutral position from the second torsion angle.

A vibration damping device equipped with a resonator mechanism comprising at least one resonator, the at least one resonator having a first beater extending from an embedded end to a free beating end. The resonator consists of an elastically deformable base equipped with a first branch and a second branch connected by a central section, the embedded end being embedded at the first branch, the first branch extending from a first end to a second end each rigidly fastened to a mount, the second branch extending from a first end section to a second end section each rigidly fastened to a vibration source.

A motor for driving a fan in a heating and/or cooling system includes a motor body, a motor cover, and an isolator. The isolator damps vibrations passed from the motor body to the motor cover. The isolator includes two isolating elements connected by a bridge. At least one of the two isolating elements includes at least two corners in a cross-sectional view.

Vehicles that are relatively heavy and/or configured to transport heavy loads may utilize a powertrain comprising an electric machine capable of operating at high speeds and a multispeed transmission to propel the vehicle. An interface module is configured to modulate torque between the electric machine and the multispeed transmission allowing the electric machine to smoothly match speed as the multispeed transmission shifts between gears. The interface module facilitates efficient, predictable, and reliable modulation of torque between an input and an output of the powertrain of the vehicle.

A torsion damper with at least one torque input disk and at least one torque output disk, wherein the torque input disk can move in circumferential direction relative to the torque output disk against the force of at least one spring storage, wherein the relative movement is damped by a friction device which generates a smaller friction torque in a first swivel angle range than in a second swivel angle range in that the friction device has at least two friction ring pairs which are rotatable opposite one another and which are activated depending on the swivel angle via a driving connection of at least one friction ring with the torque input disk. The driving connection has a spring element which is arranged functionally in series with the friction device and functionally in parallel with the spring storage.

A torque converter is provided. The torque converter includes an axially movable turbine piston and a damper assembly fixed to the turbine piston. The damper assembly includes a first cover plate, a second cover plate, a plurality of fasteners fixing the first cover plate and the second cover plate together such that the second cover plate is spaced from the first cover plate, a first drive flange axially between the first and second cover plates, a second drive flange axially between the first and second cover plates and an elastic element axially between the first and second cover plates. The first cover plate, the second cover plate, the second flange, the fasteners and the elastic element are axially movable with the piston turbine independently of the drive flange.
