A bodywork structure for a body for a public transport vehicle, in particular a railway vehicle or a road transport vehicle, for example a guided road transport vehicle, including a wall extending in a longitudinal direction, the wall including at least one cavity extending in the longitudinal direction, wherein the cavity forms a passage for a fluid under pressure, for example a gas under pressure.

A railcar body comprises at least one panel assembly having a first panel and a second panel, both extending longitudinally along the railcar body and adjacently to each other. The inner wall of the first and second panels, which are longer than their outer wall, respectively have at least a first and a second mating interface which are different from each other and compatible so as to be located at a predetermined distance from each other, thereby creating a gap of a predetermined width between two juxtaposed edges of the panels. This panel assembly is designed to be compatible with a laser welding process.

Provided is a multilayer composite that has flame retardancy and low smoking property as well as has high physical characteristics. The multilayer composite has a multilayer structure and includes at least one core layer and at least one skin layer, wherein the multilayer composite satisfies all the following conditions (A) to (D): (A) the core layer is a composite including discontinuous reinforcing fibers and a first thermoplastic resin, in which the discontinuous reinforcing fibers are randomly dispersed and bonded with the first thermoplastic resin at least at intersections of the discontinuous reinforcing fibers; (B) the skin layer is a composite including continuous reinforcing fibers and a second thermoplastic resin, in which the continuous reinforcing fibers are impregnated with the second thermoplastic resin; (C) each of the first and the second thermoplastic resins has a limiting oxygen index of 30 or higher; and (D) the first and the second thermoplastic resins are miscible with each other.

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.

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.

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.

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.

A cladding arrangement includes at least one first cladding part for a vehicle, in particular a rail vehicle, which is connectable via at least one connecting device to a running gear of the vehicle, a running gear component, a car body of the vehicle or a car body component, wherein at least one first heating device, which is directed into a hollow formed by at least the first cladding part, is connected to the at least first cladding part to provide advantageous structural conditions such that ice deposits on the vehicle may be effectively thawed.
