ABSTRACT:
The hub of a composite flywheel is made of cast steel and comprises an axial extension with an external surface which is a press fit in a disc-shaped element of the primary flywheel of the composite flywheel. A centrally located through hole of the hub is surrounded by a second surface constituting a seat for and being a press fit on the outer race of a pilot bearing for the input element of a variable-speed transmission receiving torque from the composite flywheel through a friction clutch. The extension is made yieldable so that its fitting into the disc-shaped element does not result in deformation of the second surface and does not cause problems in connection with installation of the pilot bearing in the hub. Moreover, the clearance between the pilot bearing and the hub cannot be reduced below a value which could entail premature wear upon the bearing and would shorten the useful life of the composite flywheel.
