Subassembly for a dual-mass flywheel, kinetic energy system and method for balancing of a construction and, thereby

摘要

It is a subassembly (14) for a two-mass flywheel for damping of torsional vibrations in a drive train of a motor vehicle is provided with a secondary mass (16) for conveying out one of a primary mass engageable torque, a with the secondary mass (16) additional component that is connected, in particular additional mass (26), a in the axial direction between the secondary mass (16) and the accessory component primarily arranged in the compositions of this cover (30) for the partial boundary of a from the primary mass limited receiving channel for receiving a between the primary mass and the secondary mass (16) effective energy accumulator component, in particular curved spring, and a with the secondary mass (16) connected in a frictional and sliding on the primary masses cover (30) in a contact region (36) which support sealing diaphragm (32) for sealing of the receiving channel, wherein the accessory component radially inside to the contact region (36) at least one passage opening (42) for the guiding-through of a the sealing membrane (32) of the primary masses cover (30) has abhubelements (44), lifting. Through the passage opening (42) in the accessory component (26), it is possible with the help of an inserted abhubelements (44) of the primarily masses cover (30) of the rest of the subassembly (14) during the motion and to hold or degrees, without the mass moment of inertia of the primarily masses cover (30) the force can result, so that easy balancing of a mass of the spring - mass - system of a dual-mass flywheel is made possible.
