Abstract

Un sincronizzatore per innesti, in particolare di cambi per autoveicoli, è munito di un manicotto di manovra (2) collegabile solidale a rotazione con un albero mediante spostamento assiale e munito di una dentatura interna, di un corpo (5) di innesto munito di una dentatura esterna (8), come pure di un anello (4) di sincronizzazione, il quale in direzione periferica si trova in collegamento con impegno geometrico con il manicotto di manovra attraverso una dentatura esterna (7) e si trova in collegamento con impegno di attrito con il corpo (5) di innesto. Il manicotto di manovra presenta una dentatura di inserimento e di bloccaggio, la quale consente il pervenimento in ingranamento della dentatura di inserimento del manicotto di manovra (2) con la dentatura esterna (8) del corpo (5) di innesto solamente in presenza del numero di giri di sincronismo. La dentatura di inserimento (9) disposta sulA synchronizer for couplings, in particular for gearboxes for motor vehicles, is equipped with an operating sleeve (2) which can be connected in rotation to a shaft by axial movement and equipped with an internal toothing, a coupling body (5) equipped with a external toothing (8), as well as a synchronization ring (4), which in peripheral direction is in connection with geometric engagement with the operating sleeve through an external toothing (7) and is in connection with frictional engagement with the coupling body (5). The operating sleeve has an insertion and locking toothing, which allows the insertion toothing of the operating sleeve (2) to be meshed with the external toothing (8) of the coupling body (5) only in the presence of the number of synchronous turns. The insertion teeth (9) placed on the
