ABSTRACT:
In an elastic clutch of disk design, particularly a split flywheel for an internal combustion engine, a coupling including an oblong spring is arranged between two coupling halves that are mutually rotatable. Essentially stretched in relaxed condition, the spring is subdivided in two or more partial sections by wedge-shaped spring cups, the longitudinal axes of which partial sections have relative to one another a buckled arrangement. Obtained in this way is a spring favorable for specific operating conditions, with a low spring stiffness, but with the spring being composed of essentially straight-line partial sections. Provided thereby is a spring that can be manufactured at low cost, which, in operation, is favorably stressed and not subjected to any wear.
