(EN) The invention relates to a two-mass flywheel (10) comprising an input part (12) having a primary flywheel mass (34), and an output part (20) which is delimited with respect to said input part and rotatably mounted counter to the action of at least one energy store (30) and which has a secondary flywheel mass (38), wherein the at least one energy store is comprised by the input part, forming a duct (42) extending radially in the direction of the energy store, and a flange (40) of the output part reaches through the duct as far as an end of the energy store, and wherein, in said duct, a sealing diaphragm (44) which encapsulates the energy store in a sealing manner is provided between the flange and a part of the input part that faces a secondary flywheel mass. According to the invention the sealing diaphragm is connected integrally and/or in a form-fitting manner to the part of the input part that faces the secondary flywheel mass and is supported on a plastic friction ring fixed to the flange or directly on the flange. The invention further relates to a torque transmission device having such a two-mass flywheel.
(ZH) 本发明涉及一种双质量飞轮(10)，具有：带初级飞轮质量(34)的输入部件(12)；和相对于该输入部件受限地抵抗至少一个储能装置(30)的作用能旋转地支承的输出部件(20)，输出部件具有次级飞轮质量(38)，其中，在形成径向地朝着储能装置的方向延伸的通道(42)的情况下所述至少一个储能装置被输入部件包围，输出部件的凸缘(40)穿过通道直到到达储能装置的端部上，在所述通道中，密封膜片(44)设置在凸缘和输入部件的朝向次级飞轮质量的部件之间，密封膜片密封地封装储能装置。本发明设置，密封膜片与输入部件的朝向次级飞轮质量的部件材料锁合地和/或形状锁合地连接并且支撑在一固定在凸缘上的塑料摩擦环上或者直接支撑在凸缘上。本发明还涉及一种具有这种双质量飞轮的转矩传递装置。
