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.

摘要： The application relates to roof segments for constructing a roof of a carriage body for a rail vehicle for passenger transport, in particular for use in short-haul operation, such as underground and suburban trains, the rail vehicles or the train units formed by same must be accelerated and decelerated at short intervals. The roof segments are designed in the form of plates, shells or half-shells and consist of an outer wall and an inner wall at a distance to same. At least two roof segments are configured in such a way that the protruding region of the outer wall or inner wall of one roof segment is interlockingly, force-lockingly and/or integrally connected to the non-protruding region of the outer wall or inner wall of the neighbouring roof segment. The roof segments consist at least partially of a fibre-reinforced plastic composite.

摘要： The invention relates to a head module for a rail vehicle, said head module being suitable to be detachably fixed to the front face of a subsequent railcar unit without additional underframe. The head module consists of an inner and an outer shell and includes three systems which convert, in the event of a crash, the collision energy into a deformation one after the other or simultaneously and substantially independently of another.

摘要： The application relates to a crash system for the head module of a rail vehicle, said head module being detachably fixed to the front face of a subsequent railcar unit without additional underframe. The crash system has a crash conduction element that carries a crash box at its front end and the back end of which is fixed to the underframe support of the subsequent railcar unit. In the event of a crash, crash forces are thus absorbed by the underframe of the subsequent railcar unit.
