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.
Claims21
A running gear for a rail vehicle comprising:
- a plurality of elastic sprung longitudinal members connected to one another by means of a cross-member, wherein free ends of the longitudinal members are connected to axle-boxes for rail wheels each of the longitudinal members has at least two flexural springs at the free ends to which the axle-boxes are fixed, and at least one flexural spring has a slot in a sprung area between the axle-box and the cross-member structure.
A running gear for a rail vehicle comprising:
- a plurality of elastic sprung longitudinal members connected to one another by means of a cross-member, wherein free ends of the longitudinal members connected to axle-boxes for rail wheels, each of the longitudinal members has at least two flexural springs at the free ends to which the axle-boxes are fixed, and in an unloaded state the flexural springs are deflected downwards from the cross-member structure in an S-shape.
A running gear for a rail vehicle comprising:
- a plurality of elastic sprung longitudinal members connected to one another by means of a cross-member and wheelsets guided in transversely elastic axle-boxes, wherein free ends of the longitudinal members are connected to axle-boxes for rail wheels and each of the longitudinal members has at least two flexural springs at the free ends to which the axle-boxes are fixed.
A running gear for a rail vehicle comprising:
- a plurality of elastic sprung longitudinal members connected to one another by means of a cross-member and damper elements arranged between the axle-box and the cross-member structure, wherein free ends of the longitudinal members are connected to axle-boxes for rail wheels and each of the longitudinal members has at least two flexural springs at the free ends to which the axle-boxes are fixed.
