A flexplate for a motor vehicle drivetrain includes a carry plate configured for being connected to an engine crankshaft and a drive plate. The drive plate and the carry plate are separate components attached directly via contact. The drive plate is configured for transferring torque input into the carry plate to a downstream component. A method of constructing a flexplate for a motor vehicle drivetrain includes stamping a carry plate configured for being connected to an engine crankshaft; stamping a drive plate separate from the carry plate; and attaching the drive plate and the carry plate directly together via contact. The drive plate is configured for transferring torque input into the carry plate to a downstream component.

Flexplate for connecting damper assembly to an internal combustion engine crankshaft

A clutch disc assembly, comprising a friction plate, a damper fixedly secured to the friction plate, comprising an inwardly facing saline and a retainer plate, the retainer plate comprises a first radially inwardly facing surface and a second radially inwardly facing surface radially offset from the first radially inwardly facing surface, and a hub, the hub comprises a first radially outwardly facing surface having a circumferential groove, a second radially outwardly facing surface having an outer saline that meshes with the inwardly facing saline to non-rotatably connect the hub and the damper, and an internal saline surface.

Universal damper and interchangeable hub assembly

A flywheel assembly for a prime mover includes a flywheel and a ring gear. The flywheel has a first plurality of apertures for receiving a first plurality of fasteners for fixing the flywheel to a prime mover, a first cylindrical ring portion including a first outer diameter, a second cylindrical ring portion at a first distal end of the first cylindrical ring portion and including a second outer diameter, larger than the first outer diameter, and a third cylindrical ring portion at a second distal end of the first cylindrical ring portion, opposite the first distal end, and including a third outer diameter, larger than the second outer diameter. The flywheel also has a first wall connecting the first distal end of the first cylindrical ring and a third distal end of the second cylindrical ring portion. The ring gear is engaged with the first cylindrical ring portion.

Interlock system for ring gear on flywheels

A clutch disc including a drive plate concentrically arranged about an axis of rotation, the drive plate having: a first side facing a first axial direction; a second side facing a second axial direction, opposite the first axial direction. The drive plate includes a first plurality of through-bores at a first radial distance from the axis of rotation and a second plurality of through-bores at a second radial distance from the axis of rotation, where the second radial distance is different from the first radial distance. The first and second pluralities of through-bores are arranged such that an arc passes through the first and second pluralities of through-bores.

Clutch disc with fasteners arranged at offset pitch circles

A pull-type friction clutch having an annular part that is axially clamped to a disk spring and is axially fixedly connectable to an actuation sleeve of an actuation system. The annular part has axially raised lugs on its face bearing against the disk spring, and the lugs engage in slots that are provided between the disk spring tongues where the tongues are appropriately widened, to provide a form locking connection in the peripheral direction. As a result of the peripherally fixed attachment of the annular part to the disk spring, wear caused by a relative twist between the annular part and the disk spring is prevented.
