Abstract

An axial ondular washer made from a circularly annular, flat spring material having an ondular line with maxima and minima with respect to a centre plane, wherein these maxima and minima are defined as lying on different sides of the centre plane and in each case being tangent on a plane of a first or second abutment (1, 2), which plane extends parallel to the centre plane, is to be improved with regard to its initial compression behaviour. For this purpose, an ondular washer of this type is characterized by the following features: the ondular line is composed of consecutive first and second sections, of which at least in each case two sections exist; in a first section, there is at least one ondular longitudinal region which begins and ends in the centre plane (3) and has a maximum and a minimum; in a second section, there are at least two ondular peaks having maxima or minima and elevations which lie below the spacing dimension between the delimiting planes of the abutments (1) and (2), wherein each adjacent first section is adjoined directly in each case by one of said ondular peaks.
