Abstract
La trasmissione comprende un primo gruppo di cilindri (1) di una pompa idraulica radiale che è girevole rispetto ad un'incastellatura (2) della trasmissione attorno ad un primo asse (a1) e che è solidale torsionalmente con un albero di ingresso (6) della trasmissione nonché con una scatola (15) nel cui interno ruota il primo gruppo di cilindri; un secondo gruppo di cilindri (28) di un motore idraulico radiale che è girevole rispetto all'incastellatura attorno ad un secondo asse (a2); un albero di uscita (60) della trasmissione il cui asse (a3) è disposto tra i due assi suddetti (a1, a2) ed al quale è solidale una ruota dentata (62) ingranante con una ruota dentata (64) solidale alla suddetta scatola (15) nel cui interno ruota il primo gruppo di cilindri e con un'altra ruota dentata (63) solidale al secondo gruppo di cilindri; mezzi atti a variare la cilindrata del primo e del secondo gruppo di cilindri e mezzi di distribuzione atti a mettere in comunicazione alternativamente i cilindri del primo gruppo (1) con i cilindri del secondo gruppo (28).
