bridge type trackless electric vehicle for the transport of passengers, cargoes and for non transport works and method of manufacture of such a bridge

摘要

the application describes a bridge type trackless electric vehicle for the transport of passengers, cargoes and for non transport worksmade of metallic material with a beam (2) and at least one made of a metal material, a longitudinal lever (8), etc.which has a coupling part with the installation hole, in which a u043fu043eu043bu044bu043c connection piece (4) has a beam (2) on landing.the beam (2) and a longitudinal lever (8) rigidly connected without the possibility of each on the other.in this bridge properties of metallic materials the connective part of the lever and the connecting area of the longitudinal beams mutually agreed sothe elastic modulus of longitudinal elasticity less than the coupling lever module connecting area of the beams.and / or tensile strength of connective parts of the longitudinal lever more limit strength connecting area of the beams, and / or the true yield ReS metal u0438u0447u0435u0441u043au043eu0433u043e materialwhich is the coupling of longitudinal lever, or, if such a metallic material is not expressed the true yield stress, ca u043bu043eu0432u043du044bu0439 yield Rp0,2 above the ReS respectively a rp0,2 yield stress of metal materialwhich is covered by the connecting part of the longitudinal lever connecting the beams.
