Abstract

Secteur technique : accouplements à friction pour boîtes de vitesses. Caractéristique technique principale : un piston de serrage 13 ou 14 d'un accouplement à disques 17, 18 ou 17', 18' est disposé dans un alésage 11 ou 12 porté par un manchon d'accouplement 1, cet alésage étant alimenté par un canal d'amenée de fluide 29 ou 30 porté par l'arbre mené 2. Application technique principale : commande de boîtes de vitesses.Technical sector: friction couplings for gearboxes. Main technical characteristic: a clamping piston 13 or 14 of a disc coupling 17, 18 or 17 ', 18' is arranged in a bore 11 or 12 carried by a coupling sleeve 1, this bore being fed by a channel fluid supply 29 or 30 carried by the driven shaft 2. Main technical application: gearbox control.
