METHOD AND PRODUCT FOR CONICAL SPRING HAVING VARIABLE STIFFNESS AND CAPABLE OF PREVENTING FOLDING AND CRACKING

Document Type and Number:

WIPO Patent Application WO/2016/145668

Kind Code:

A1

Abstract:

Disclosed is a method of a conical spring having a variable stiffness and capable of preventing folding and cracking. A rubber metal spring in a conical arrangement is formed altogether by a rubber body (2), an inner conical body (1) and an outer conical body (3) of the conical spring. An upper rubber profile of the rubber body is a multiple-section ramp-down structure, and a lower rubber profile of the rubber body is a multiple-section ramp-up structure. By changing the shape, slope, length and the number of sections of each of the multiple sections of the ramp-up and ramp-down structures, the variable stiffness of the conical spring can be adjusted several times, and the folding and cracking of the conical spring can be prevented. Further provided is a conical spring implementing this method.
