摘要

Sinous spring in the form of a closed ring comprises a number of individual undulations, each consisting of a peak and a trough. The undulation course is designed to achieve a spring characteristic curve that increases as the length of the deflection path increases in an initial zone (C) that can be pre-determined. In this initial zone, as the length of the deflection path increases, the number of undulating zones that transmit forces also increases. Preferred Features: The initial zone is limited to 10-80% of the maximum deflection path.
