Problems solved by technology

[0004] In short, the jacket of patent FR 2 881 990 is quite cumbersome to assemble and its use is very limited on pierced shafts, not to mention its cost price

Embodiment Construction

[0019] refer to figure 1 , in a railway vehicle, the shaft 1 is in the form of a cylindrical shaft mounted transversely under the body of the vehicle, passenger car, freight car or locomotive, which supports the wheels 2 located at both ends and fixed with 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] refer to figure 2 and 3 , the axle 1 here is protected by an overcoat 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 out...

Abstract

This is a protective jacket for railway vehicle axles (1). It includes an outer armor layer (61) and an inner layer (62) for damping deformation of the outer armor layer (61). The outer layer (61) is provided on one side of the inner layer (62), the other side where the inner layer is applied to the shaft (1) is bare, and the outer layer (61) has two closed edges (63, 64) , the two closed edges are designed to receive a closure strip of the jacket (6) designed to keep said edges (63, 64) connected to each other.

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...
