Embodiment Construction

[0019] Referring to FIG. 1 , in a railway vehicle, an axle 1 is in the form of a cylindrical shaft mounted transversely under the vehicle, passenger car, freight car or locomotive body, which supports wheels 2 located at both ends and secured by journals 5 . When the shaft 1 is in use, the wheels 2 contact rails 4 laid on the ballast receiving surface.

[0020] Ballast is the name given to the bed of stones or gravel that is laid along the road along which the railroad tracks are laid. Its function is to transmit the force generated when the train passes to the ground without deforming the ground due to compression. Ballast also serves to lock the rails in position against longitudinal deformation.

[0021] Referring to Figures 2 and 3, the shaft 1 here is protected by a jacket 6 to prevent the impact of the ballast 3. The jacket consists of two overlapping layers 61 , 62 , namely an outer armor layer 61 and an inner layer 62 which reduces deformation of the outer armor laye...

Abstract

The invention provides a protective cover for railway vehicle axle (1), comprising an armoured outer layer (61) and an inner layer (62) for damping deformation of the armoured outer layer. The outer layer (61) is arranged on one side of the inner layer (62), and the other side of the inner layer is applied to the axle (1) is bare, and the outer layer has two blocked edges (63, 64) designed into a blocked strip for receiving the cover (6) and connecting the edges (63, 64) together.

Description

technical field [0001] The present invention relates to a protective jacket for railway vehicle axles comprising a relatively hard outer layer of armor to withstand the impact of ballast blocks without splintering, and a relatively flexible inner layer to dampen deformation of the armor. This armor must not splinter, since the occurrence of any cracks creates a risk of corrosion and damages the surface of the shaft. Background technique [0002] Patent FR 2 881 990 already discloses a protective jacket of this type. The jacket has a layer of butyl mastic for the armor. Because butyl rubber is a very viscous material that would be difficult to remove from the shaft body if it were applied directly to the shaft body without an inner layer, patent FR 2 881 990 proposes the use of a The armor is lined with the removed inner layer, specifically an aluminum layer coated with a vinyl or acrylic adhesive compound. [0003] Although the adhesive-coated aluminum layer is relatively...
