Dual mass flywheel (2) which forms part of the drive transmission between an engine crankshaft (4) and a clutch shaft (6) connectable to the latter and incorporates a first flywheel body (12) which is drivingly connected to the crankshaft, and a second flywheel body (14) which is rotatable relative to the first flywheel body (12) and is connected to it by springs (18) engaged between the flywheel bodies. These springs (18) are directed substantially radially with respect to the axis of the flywheel (2) and have their radially inner ends pivotally attached to the first flywheel body (12) and their radially outer ends pivotally attached to the second flywheel body (14). Between radially inner parts of the flywheel bodies (12, 14) there is a centrifugal clutch (40) which keeps the flywheel bodies locked together by friction at lower engine speeds and frictionally disengaged from one another at higher engine speeds. The second flywheel body (14), by means of its socket-like hub (26) via a rolling bearing (30), is mounted externally on the hub portion (22) of the first flywheel body (12). |
