Abstract
A rail vehicle, particularly a monorail, has several vehicles or cars, each of two adjacent or neighboring ones of which are connected by way of an associated coupling device. Between each two adjacent vehicles or cars there is mounted a bogie with an axle suspension for supporting wheels and guide wheels running on a track. A guide arrangement is provided between the adjacent vehicles or cars. This guide arrangement together with a connecting joint of the coupling device forms a single substantially vertical steering axis. This single substantially vertical steering axis passes in a vertical median longitudinal plane of the vehicles or cars both through the connecting joint and through bogie-side guide rod bearings and through a wheel axle of the supporting wheels, so that, particularly with regard to quiet travel and straight line passage, the dynamics of vehicle travel or movement are improved.
