Abstract
The coach body construction comprises an upper structure having extruded profiles, which are connected detachably to one another by corner connectors and are made of an aluminum alloy, and a lower structure. The lower structure is composed of longitudinal and transverse supports which are made of an extruded aluminum alloy and are detachably connected to one another and to the upper structure by corner connectors. In interaction with the upper structure, it is of inherently sturdy construction. The corner connectors are, in particular, screw-on corner connectors.
Claims23
A coach body construction for a rail vehicle, said coach body construction comprising:
- a lower structure including longitudinal supports and transverse supports detachably connected together;
- said longitudinal supports for said lower structure comprising at least one inner support and at least two outer supports;
- each said inner support comprising an extruded aluminum alloy profile having two undercut longitudinally extending grooves along at least one side;
- each said outer support comprising an extruded aluminum alloy profile having at least two undercut longitudinally extending grooves along at least one side;
- each said transverse support comprising an extruded aluminum alloy profile having at least two undercut longitudinally extending grooves along at least one side;
- means for detachably connecting said supports together to form said lower structure, said connecting means comprising nut means received in each of said longitudinally extending grooves, corner connection means having limbs and screw holes, said corner connection means being positioned externally of each of said longitudinally extending grooves and between adjacent ones of said longitudinal and transverse supports extending substantially perpendicular to each other, and screw means for detachably connecting a respective one of said corner connection means to a respective one of said nut means within said longitudinally extending grooves.
A coach body construction for rail vehicles which comprises:
- an upper structure of inherently sturdy construction including posts and upper flanges;
- said posts and said upper flanges being formed by extruded aluminum alloy profiles;
- said posts and said upper flanges each having two undercut longitudinally extending grooves for receiving nuts extending along at least one side;
- a lower structure detachably connected to said upper structure;
- said lower structure including longitudinal and transverse supports;
- each of said longitudinal and transverse supports being formed by an extruded aluminum alloy profile;
- and
- each of said longitudinal supports and at least some of said transverse supports having two undercut longitudinally extending grooves extending along at least one side for receiving nuts and to provide rigidity to the coach body construction.
