Abstract

Un sistema di bloccaggio differenziale per assali motori sterzanti è dotato di due gruppi di dischi e controdischi, in cui il rispettivo gruppo di dischi è montato in modo fisso su una ruota dentata conica solidale con un albero di uscita del differenziale ed il rispettivo gruppo di controdischi è montato in modo fisso su una scatola portasatelliti solidale con una corona del differenziale. Il sistema di bloccaggio è atto a bloccare automaticamente il differenziale tramite i due gruppi di dischi e controdischi ed è anche atto a bloccare totalmente detto differenziale tramite una spinta assiale di due pistoni azionati tramite olio in pressione proveniente da una pompa. Questa pompa, collegata con i due pistoni tramite una canalizzazione, è una pompa ad ingranaggi interni ed è disposta all'interno dell'assale. La pompa viene azionata direttamente da un albero d'ingresso del differenziale.A differential locking system for steered driving axles is equipped with two groups of discs and counter-discs, in which the respective group of discs is fixedly mounted on a conical toothed wheel integral with a differential output shaft and the respective group of counter-discs it is fixedly mounted on a satellite holder box integral with a differential crown. The locking system is able to automatically block the differential by means of the two groups of discs and counter-discs and is also able to totally block said differential by means of an axial thrust of two pistons operated by means of pressurized oil coming from a pump. This pump, connected to the two pistons through a channel, is an internal gear pump and is located inside the axle. The pump is driven directly by a differential input shaft.
