ABSTRACT:
A double-mass flywheel for installation between an internal combustion engine and a transmission. A first flywheel mass associated with the crankshaft of the engine has the shape of a first U which opens radially inward and each of the arms of the U forms a side disk. A second flywheel mass associated with the transmission has the shape of a second U which opens radially outward toward the circumference. The second U engages as a center disk between the two side disks. The two masses are turnable to a limited extent with respect to each other, with the interposition of elastic members which rest at least indirectly on the one side against the first mass and on the other side against the center disk. Damping elements are interposed between the two masses and extend parallel to the elastic members. The center disk is formed of three concentric, partial disks, comprising an inner partial disks and two outer partial disks. These three partial disks have projections which form stop surfaces, with projections of the inner partial disk cooperating with projections of the two outer partial disks. Each end of an elastic member rests against one of the outer partial disks.
