Abstract
A composite flywheel having coaxial primary and secondary flywheels, which can turn relative to each other against the opposition of one or more friction generating devices and/or dampers, employs a substantially cup-shaped carrier with one or more signal generators in the form of notches, recesses, grooves, holes, projections or the like. The carrier includes a radially inwardly extending washer-like portion and a sleeve-like portion, which sleeve-like portion is in one piece with the radially outermost part of the washer-like portion. The signal generator(s) is (are) provided in or on that part of the sleeve-like portion which projects outwardly beyond a sleeve-like part of the radially outer end portion of the primary flywheel. The sleeve-like part of the end portion of the primary flywheel surrounds and confines the washer-like portion and is welded to the sleeve-like portion of the carrier.
