摘要： The invention relates to a method for connecting a connection piece to a U-shaped ring anchor for a head module for rail vehicles, the head module consisting predominantly of fiber-reinforced plastic material and having an outer shell and the ring anchor consisting of fiber-reinforced plastic material and being arranged in the roof region of the outer shell as a stiffening means. According to the method, connecting elements are fed through the dry or matrix-material-impregnated, unconsolidated fiber reinforcement structure of the ring anchor.

摘要： A device for connecting a cross member for receiving pivot pins on two lower longitudinal members of a car body for a rail vehicle. The cross member has a transversal part that connects the two longitudinal members to each other in the region of the connection, and a longitudinal part that extends to the closest car front. The lower longitudinal members extend over the complete length of the car body and consist of multi-chamber hollow profiles made of a fibre composite material. The number of chambers of the multi-chamber hollow profile of each longitudinal member is reduced in the region of the connection such that the wall material of at least one chamber was removed in such a way that the webs to the adjacent chambers are exposed. At these places, load-introducing elements engage, to which load-introducing elements the cross member is attached.
