AXIS wheelset for rail vehicles equipped with shock protection STONES AND ITS MANUFACTURING METHOD

摘要

1. The axis (11) of the wheelset for rail vehicle, which has a shell (13) serving as protection against being hit by stones, characterized in that the shell (13) has a metallic component (14), which is the maximum of the same quality as forming the boundary surface (17) of the wheelset axis material.2 metal. The axis (11) of the wheelset according to claim 1, characterized in that the metal component (14) membrane (13) consists of the same metal material, particularly steel, which itself axis (11) of the wheel pary.3. The axis (11) of the wheelset according to claim 1 or 2, characterized in that the metal component (14) contains a structural shell phase (15, 18), which increases the strength of the casing against shocks kamney.4. The axis (11) of the wheelset according to claim 3, characterized in that the structure phase is formed by particles (18) of a solid, wherein the particles (18) embedded in a solid metallic component (14) membrane (13) .5. The axis (11) of the wheelset according to claim 3, characterized in that the phase structure is formed pseudoplastic or pseudoelastic metal particles (15) or particles of material whose modulus is at most 1/10 the modulus of elasticity of the metal component (14) membrane (13), wherein the particles (15) embedded in the metallic component (14) membrane (13) .6. The axis (11) of the wheelset according to claim 1, characterized in that the metal component (14) membrane (13) is covered pseudoelastic or pseudoplastic splavom.7. The axis (11) of the wheelset according to claim 1 or 2, characterized in that between the boundary surface (17) of the shaft (11) of the wheelset and the sheath (13) includes a separating layer of electrochemically less high quality material than forming c
