FREIN A COMMANDE HYDRAULIQUE MUNI D'UN DISPOSITIF EVITANT UNE ELEVATION DE TEMPERATURE EXCESSIVE DU LIQUIDE HYDRAULIQUE

摘要

A hydraulically controlled brake is equipped with a device preventing an excessive rise in temperature of the hydraulic fluid. The control piston of the brake comprises a cup-shaped piece and also an insulating core accommodated in the cup and having a free end face via which the piston pushes on the friction element. The core is screwed onto a central threaded column projecting from the bottom of the cup.
