Abstract: 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.

Abstract: The invention relates to a bogie for a rail vehicle characterized by a high lightweight construction potential. The bogie (1, 1*, 1**) according to the invention has, for primary suspension, a torsion spring system (12) in the inner volume of which a roll stabilizer having a torsion rod (11) is arranged in a torsionally movable manner. The roll stabilizer can be articulated to the car body of the rail vehicle or to the torsion spring system (12). The bogie (1, 1*, 1**) according to the invention advantageously has a particularly large installation space for built-in components.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The application relates to a method for producing a hollow support from a fiber composite material, to a core designed as a hollow body, to the use of said core, and to the use of said hollow support made from fiber composite material.

Abstract: 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.

Abstract: The invention relates to bogies for railway vehicles with at least two wheelsets mounted in axleboxes and at least one transverse member. The bogies are in particular characterized in that they have a lightweight design and can be produced at low cost. The axleboxes of a wheelset are articulated to the transverse member via two axle levers so that the axle levers form an H shape with the axleboxes and the transverse member. The transverse member has at least two torsion bars arranged in parallel to the axles of the wheelsets, said torsion bars being firmly connected to the transverse member. The torsion bars have spring levers so that the end portion of the spring lever not connected to the torsion bar acts upon the axlebox.

Abstract: A connecting element for fastening connection pieces to fiber composite components made of at least one fiber layer and of matrix material is provided, the connecting element has a screw- or bolt-like shape, the connecting element includes a tip at one end thereof, which tip supports the penetration of the fiber layers of the fiber composite component in the dry or matrix-impregnated, unconsolidated state, and comprising a casing in the region that comes in contact with matrix material of the fiber composite component, but at least in the region that comes in contact with the reinforcing fibers of the fiber composite component.

Abstract: A car body has at least: two lateral walls, each of which is made of a lower and upper longitudinal member that are connected by multiple lateral wall segments and vertically arranged columns, a roof, a base, two end walls or one end wall, and a head module, wherein the lower longitudinal members of the two lateral walls are connected to the base by means of connection elements in the longitudinal direction of the car body, and the upper longitudinal members of the two lateral walls are connected to the roof by means of connection elements in the longitudinal direction of the car body. The lower and upper longitudinal members are designed as multichamber hollow profiled sections which are continuous over the entire length of the car body, the lower and upper longitudinal members are made of fiber-reinforced plastic, and the connection elements at least partly consist of metal.
