Abstract

Si propone un dispositivo di sterzatura totalmente idraulico per veicoli, con una pompa idraulica (2) comunicante con una valvola di comando (4) azionabile mediante un volante di guida (5), con una disposizione di motore di sterzatura (8) ed un misuratore di sterzatura (7) che determina la quantità di fluido idraulico da alimentare alla disposizione di motore di sterzatura (8) attraverso la valvola di comando (4).Relativamente ad un siffatto dispositivo di sterzatura si intende ridurre con mezzi semplici lo sforzo fisico del conducente durante le operazioni di manovra. A tale scopo è previsto un dispositivo di azionamento (13), il quale all'azionamento blocca, per mezzo di un freno (15), meccanicamente il misuratore di sterzatura (7) e così impedisce un azionamento del misuratore di sterzatura (7) mediante il fluido idraulico, mentre per mezzo di una valvola di cortocircuito (14) stabilisce un cortocircuito per il fluido idraulico per il misuratore di sterzatura (7).(fig. 1).
