摘要

b "method of manufacture of a lateral bearing of railway wagon, a spring to a side bearing of railway wagon.An apparatus for energy absorption for a railway wagon and a spring for an energy absorbing device for a railway wagon "this invention describes a method for the manufacture of U.Ma elastomeric spring adapted for use in combination with an energy absorbing device for railway wagon.The method of the present invention involves the step of stabilization of the elastomeric spring before insertion of the apparatus for energy absorption in the railway wagon.The stabilisation of the elastomeric spring is effected by subjecting the elastomeric element to a predetermined compression standard which consists of a series of repeated cycles of compression ind.Ividuais.The cyclic compression of the elastomeric element in predetermined repeat pattern prior to the installation of the apparatus for energy absorption in the railway carriage performs the permanent deformation of the elemeNt of elastomeric while maintains the preload force developed for the appliance of energy absorption, remain in a substantially constant maximized level that simulates a condition ofSgaste predetermined for the appliance of energy absorption.
