Abstract

L'invenzione si riferisce a un dispositivo di propulsione con un motore idraulico (1) ed una trasmissione meccanica inserita a valle.Sono previsti due innesti di frizione (7, 8) azionabili idraulicamente, attraverso i quali il motore elettrico può essere collegato con la trasmissione. Uno degli innesti di frizione agisce come freno ed adempie alla funzione di un freno ausiliario e/oppure di stazionamento. Secondo l'invenzione gli innesti di frizione (7, 8) sono azionabili attraverso una conduttura (6) comune della pressione di comando. L'azionamento ha luogo in modo tale che il primo innesto a frizione, servente al collegamento del motore idraulico con la trasmissione, nel caso di pressione di comando applicata viene chiuso e, nel caso di pressione di comando diminuente, é aperto. In tal modo il motoreThe invention relates to a propulsion device with a hydraulic motor (1) and a mechanical transmission inserted downstream. Two hydraulically operated clutch couplings (7, 8) are provided, through which the electric motor can be connected to the transmission. One of the clutch couplings acts as a brake and fulfills the function of an auxiliary and / or parking brake. According to the invention, the clutch couplings (7, 8) can be operated through a common conduit (6) of the control pressure. The actuation takes place in such a way that the first friction clutch, used to connect the hydraulic motor with the transmission, in the case of applied control pressure, is closed and, in the case of decreasing control pressure, it is open. Thus the engine
