Problems solved by technology

[0004] The disadvantage of the above technique is evident when an outer rail made of a high strength, hardened material or a material with a high tensile yield value and thus high durability is to be applied to the bottom rail, since such materials form Very difficult
Even the envelope attachment obtained in this way between the outer and bottom rails starts off very well, but loosens after a while of use, which often results in rattling and noise from the rails

Embodiment Construction

[0024] FIG. 1 illustrates an embodiment of the guide rail according to the invention, which in this case constitutes a so-called railway track generally comprising a base 1 , a web 2 and a main part 3 .

[0025] Referring to Figures 2 and 3, the guide rail of the present invention is mainly composed of two parts; a first part 4, which in this example consists of a single outer rail made of sheet metal of limited or relatively small thickness, and a second part 5, in the In this case it includes the bottom rail. The term bottom rail hereinafter denotes an element made of beams, rods or similar thick solid material which has been prepared to receive the outer rail 4 by a machining stage after rolling. In new manufacture, the bottom rail is initially given the required shape during a rolling process. Through said preparatory phase, the outer rail 4 and the base rail 5 are given a shape so that the relatively thin-walled outer rail 4 can be received without deformation and suppor...

Abstract

The present invention relates to a composite guide rail and a method for producing such a guide rail. Said guide rail is made like a railway track or the like and is intended to be guided in interaction with the wheels of the running means along the rail, said guide rail comprising: a long outer rail (4) made of sheet metal, the shape of which is is in the shape of a longitudinally open slot with a defined inner side (9) and outer side (10); a long bottom rail (5) with a rail bottom (1) for mounting the rail on one surface; a rail waist (2), It extends from the base of the rail supporting the main part (3), which is thicker than the rail waist and acts as a receptacle (11) for receiving and supporting the outer rail, which has a selected part to provide The outer contour of the interaction of the idler pulleys. According to the invention, the inner side (9) and the receiving part (11) of the outer rail (4) have opposite cross-sectional shapes, the yield limit of the outer rail (4) exceeds the yield limit of the bottom rail (5), and the two parts are bonded by gluing are joined together, for example by welding or gluing.

Description

technical field [0001] The invention relates to a method for producing a composite guide rail according to the preamble of claim 1 and a guide rail according to the preamble of claim 18 . Background technique [0002] There is an increasing demand for wear resistance and durability of guide rails for guiding devices that can run along them, such as train cars or locomotives, by interacting with wheels or rollers. Among other things, it is thus required that the components of the rail interacting with the wheels can withstand long-term use without so-called surface fatigue and subsequent cracking. Furthermore, it is required that the guide rails should be resistant to deformation, wear and so-called micro-corrosion should not form on the wheel-rail contact surfaces of the rails, since not only damage to the service life of the train but also the comfort of the passengers is reduced. When it comes to the guide rails that form part of railway tracks, these requirements have pr...
