Abstract
A running gear for a rail vehicle includes a front and a rear wheel sets, each provided with left and right wheels. A passive hydraulic wheel set steering system includes a control valve hydraulically connected to hydro-mechanical converters for converting motion of each of the wheels towards and away from the median transverse vertical plane. The control valve is movable between a first position in which the front left and right hydro-mechanical converter assemblies are disconnected from the rear left and right hydro-mechanical converter assemblies, and a second position in which each of the front left and right hydro-mechanical converter assemblies is connected to at least a respective one of the rear left and right hydro-mechanical converter assemblies.
