Abstract

Patente de Invenção: <B>"MOLA DE CARGA INTERMEDIáRIA PARA UM SISTEMA DE DESEMBREAGEM DE UMA EMBREAGEM DE AUTOMóVEL"<D>. A invenção refere-se a um sistema de desembreagem (1) acionado hidraulicamente para uma embreagem de fricção de automóvel, que consiste em uma unidade de êmbolo-cilindro, na qual está disposto de modo deslocável um êmbolo anular (8), no lado terminal do qual está fixado um mancal de desembreagem (10), que está apoiado na embreagem de fricção com fecho devido à força por meio de uma mola de pressão (13). De acordo com a invenção, a mola de pressão (13) compreende espiras terminais (14a, 14b) cujo contorno externo se distingue em medida de um contorno externo das espiras intermediárias (15).Invention Patent: <B> "INTERMEDIATE LOAD SPRING FOR AN AUTOMOBILE CLUTCH RELEASE SYSTEM" <D>. The invention relates to a hydraulically operated disengagement system (1) for an automobile friction clutch, which consists of a piston-cylinder unit, in which an annular piston (8) is disposable on the end side of which a release bearing (10) is attached, which is supported on the friction clutch with closure due to the force by means of a pressure spring (13). According to the invention, the pressure spring (13) comprises terminal turns (14a, 14b) whose external contour is distinguished in measure from an external contour of the intermediate turns (15).
