Car body for a rail vehicle

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.

         6 . The coach body according to  claim 1 , wherein the multi-chamber hollow profiles of the upper longitudinal beams have at least two, particularly preferably three to five chambers. 
     
     
         7 . The coach body according to  claim 1 , wherein the multi-chamber hollow profile of a lower longitudinal beam has at least two, particularly preferably three chambers at the ends of the coach body. 
     
     
         8 . The coach body according to  claim 1 , wherein the multi-chamber hollow profile of a lower longitudinal beam has two chambers at least in an area of the coach body. 
     
     
         9 . The coach body according to  claim 1 , wherein the multi-chamber hollow profiles of the lower and upper longitudinal beams are formed along the longitudinal axis of the coach body as independent sections, which are connected to each other on their end faces. 
     
     
         10 . The coach body according to  claim 1 , wherein the chambers of the lower and upper longitudinal beams are separated from each other by webs and are surrounded by at least an outer wall which consists of one or more plies of fibre-reinforced plastic composite. 
     
     
         11 . The coach body according to  claim 1 , wherein the chambers of the lower and upper longitudinal beams are formed as polygonal cross sections, wherein the cross sections are designed rounded at the corners. 
     
     
         12 . The coach body according to  claim 1 , wherein the upper and the lower longitudinal beam have a local reinforcement at least in an area of the outer wall and/or of the web. 
     
     
         13 . The coach body according to  claim 1 , wherein in the area of the local reinforcement of the upper and lower longitudinal beam, filling areas between the individual plies and/or filling spandrels are filled with continuous filaments. 
     
     
         14 . The coach body according to  claim 1 , wherein at least one interply is arranged in the area of the local reinforcement of the upper and the lower longitudinal beam. 
     
     
         15 . The coach body according to  claim 1 , wherein the chambers of the lower longitudinal beams are formed as triangular and/or rectangular cross sections, wherein the cross sections are designed rounded at the corners. 
     
     
         16 . The coach body according to  claim 1 , wherein at least one chamber of the upper longitudinal beams is formed in cross section as a right-angled polygon and at least one chamber of the lower longitudinal beams is formed in cross section as a right-angled polygon, wherein the cross sections are designed rounded at the corners.
