A double damped flywheel, in particular for motor vehicle, comprising means improved by friction of the vibration damping

摘要

The double flywheel consists of two coaxial rotary weights (1,2) connected to driving and driven shafts with the second weight forming a reaction plate of a friction clutch. The two weights are connected by a ball bearing (5) with at least one of its rings (8, 9) welded to the adjacent weight, e.g. to the transverse surface of a collar on the weight which projects axially towards the bearing. The two bearing rings are welded to the central sections of the first and second weights respectively, and in a variant of the design the second weight can be in two sections - an outer section forming the clutch reaction plate, and an inner one forming a hub. In addition, the flywheel incorporates radial elastic dampers between the two weights.
