Abstract

In order to achieve in a truck for a track vehicle with an H-shaped truck frame which consists of a composite fiber structure serving the function of a primary spring, with two longitudinal beams connected to each other via transverse beams, a distribution of the loads of the truck frame suitable for composite fibers, the frame contains a torsion-elastic central plate member which couples the longitudinal beams to each other independently of the transverse beams, is designed in the truck plane as a frame stiffening element, is provided with load introduction points for the longitudinal and transverse support of the vehicle body and is designed as a bending-stiff composite fiber component for the transmission of longitudinal and transverse forces between the load introduction points and the longitudinal beams.
