  • Dual-mass flywheel having radially arranged wire cushion bodies
    Patent number: 8062135
    Abstract: A dual-mass flywheel has a first mass body and a second mass body which can rotate relative to one another by way of a damping device disposed between the first mass body and the second mass body. The damping device includes, running in the shape of an arc, at least one helical compression spring, which introduces spring force into the mass bodies via contact surfaces formed on the first mass body and the second mass body. The helical compression spring is guided in the radial direction by a wall formed by a mass body. At least one friction-reducing sliding component in the form of a wire cushion body is provided between the wall and the helical compression spring.
