Abstract
A running gear for a rail vehicle having sprung longitudinal members of plastic, connected to one another by means of a cross-member structure and at their free ends to axle-boxes for rail wheels. In order to obtain optimal stability of the wheelset guidance with reduced loading of the sprung longitudinal members, the longitudinal members each has at least two flexural springs between the ends of which in each case an axle-box is fixed in symmetrical arrangement.
