Abstract

In un cambio di velocità settoriale per autoveicoli, eseguito come trasmissione epicicloidale (2) un ruota planetaria (3) viene azionata da un albero di uscita (4) di un preinserito cambio di velocità fondamentale, mentre un portasatelliti (8) della trasmissione epicicloidale (2) è accoppiato solidale alla rotazione con un albero condotto (9) del cambio di velocità settoriale. Per inserire un gruppo settoriale, demoltiplicato, del cambio di velocità settoriale, tramite un primo giunto di manovra (13) una corona dentata interna (6) della trasmissione epicicloidale (2) viene accoppiata con una scatola cambio (1). Utilizzando mezzi di manovra costruttivamente semplici si intende evitare in un gruppo settoriale moltiplicato, in cui ha luogo una trasmissione diretta, una trasmissione di coppia tramite la trasmissione epicloidale (2). A tale scopo è previsto un secondo giunto di manovra (19)
