Definitions
- the invention relates to an axle for a rail- ⁇ bundenes vehicle having as a stone impact protection sheathing lung. Furthermore, the invention relates to various methods for producing a sheathing as Steinschlag- contactor on such a wheelset shaft for rail vehicles.
- Wheelsets of rail vehicles are damaged by a rockfall from the ballast bed or damage can be limited in terms of their impact.
- the fluidized ballast stones hit namely with relative speeds of up to 100 m / s in the yield rotie- circumferential surface of the shaft and thereby cause a ⁇ impact crater in the steel with a depth in the single-digit millimeter range. Therefore, there is a desire to protect the exposed surface parts of the lateral surface of the shaft with a shield against the stone chipping.
- the object of the invention is to improve a rockfall ⁇ protection as a casing of a wheelset to the effect that an effective protection against falling rocks is achieved and at the same time a corrosion attack of the
- Wheel set shaft can be prevented. Furthermore, the object of the invention to provide method for producing a cladding as a stone impact protection on the initially mentioned axle, with which an outer shell, with the aforementioned property profile of a sufficient rockfall ⁇ protection and an effective corrosion protection herstel ⁇ len leaves.
- the Umman ⁇ tion has a metallic component that is at most as noble as the interface of the wheelset forming metallic material.
- metallic materials and metal ⁇ metallic components in the sense of this invention metals or metal alloys are to be understood. That the metallic component is at most as noble as the metallic material of the axle or drive ⁇ is less noble than this means in other words that the metallic component having a ge ⁇ ringeres standard hydrogen electrode potential should, as the metallic material of the axle.
- the Um ⁇ coat can be designed to 100% of this metallic component. However, it is also possible that the me ⁇ tallische component makes up only a part of the sheath, such. B.
- the metallic component forms a metalli ⁇ cal matrix in which a further structural phase is distributed.
- the coating should in the broadest sense any understood the upper surface of the axle assembly covering the ⁇ . This may be particularly one on the axle befind ⁇ Liche layer. However, it can also be a Ver ⁇ formwork, which is self-sustainable.
- the casing consists of a metallic component
- the sheathing can therefore ensure effective protection against falling rocks.
- the ductile behavior of the metallic component also ensures that, in the case of a rockfall, the casing does not fail due to brittle fracture.
- the stone impact can only lead to a local plastic deformation of the casing, wherein the protection of the casing is maintained until the plastic deformation leads to ei ⁇ nem breakdown of the same up to the surface of the axle.
- the sheath to-minimum is at most as noble at the interface of the axle as the metallic material of the axle legal ⁇ ensure that at the interface between the Ummante ⁇ development and the axle no electrochemical Lokalele ⁇ training, which leads to a dissolution and thus corrosion the wheelset shaft could lead.
- a standard hydrogen electrode potential of the metallic component which approximately corresponds to that of the metallic material of the wheelset shaft, no effective local elements will form. If the shell, with its metallic component even significantly less noble than the metallic material of the axle, the outer shell acts as a sacrificial anode and is accordingly set ⁇ dissolves upon occurrence of corrosion, while the axle is spared from corrosive attack.
- the second object mentioned above is also achieved by a method for producing a shell on the wheelset shaft, in which the shell is produced by cold gas spraying, by particles of a first type with a metallic component which is at most as noble as the interface of the Radsatzwelle forming metallic Werk ⁇ material, are applied to the wheelset.
- the object can also be achieved by a method in which the sheath is produced as an envelope, with which the wheelset shaft is wound.
- a coating method is provided OF INVENTION ⁇ dung according to, ie, the sheath forms a layer on the axle.
- the sheath is a self-supporting component, which is designed as a sheath. This will then be around
- This closure can preferably also be carried out by cold gas spraying.
- Cold gas spraying is a process known per se, in which particles intended for the coating are accelerated by means of a convergent-divergent nozzle, so that they adhere to the surface to be coated on account of their impressed kinetic energy.
- the kinetic energy of the particles is used, which leads to a plastic deformation of the same, wherein the coating particles are melted when hitting only on its surface. Therefore, this method is referred to as cold gas spraying in comparison to other thermal spraying methods, because it is carried out at comparatively low temperatures at which the coating particles remain substantially fixed.
- a cold gas spraying system which has a gas heater for heating a gas.
- a stagnation chamber is connected, which is connected on the output side with the convergent-divergent nozzle, preferably a Laval nozzle.
- Convergent ⁇ divergent nozzles have a converging section and a widening section, which are connected by a nozzle neck.
- the convergent-divergent nozzle generates a jet of powder in the form of a gas stream with particles in it at high speed.
- the cold gas spraying is for example from DE
- a structural phase that increases the stone chip resistance of the Ummante ⁇ ment can, for. B. be formed by hard particles, wherein the particles in the metallic component of
- Ballast bed of the track fill can also be activated another protective mechanism of the hard particles.
- these are in fact destroyed, and the will be lost energy applied to Zer ⁇ disorder, whereby the in- sert any metallic matrix is relieved.
- the hard material particle ver ⁇ says in this case, but remains for the metallic matrix and can continue to exercise their protective function. At least the plastic deformation of the metallic component of the cladding which forms the metallic matrix is reduced by the destruction of the hard material particle or of several hard material particles.
- pseudo-plastic or pseudo-elastic metallic particles or particles of a material whose modulus of elasticity is at most one tenth of that of the metal ⁇ metallic component of the sheath is formed.
- these particles are embedded in the manner already indicated in the metallic component which forms the metallic matrix.
- pseudo-elastic metallic particles which are preferably formed from shape memory alloys such as TiNi, also plastics into consideration.
- the higher elasticity of these particles means that shocks can be intercepted elastically in the context of a rockfall, and bounce the stones of the casing according to the invention, in which case a comparatively lesser lasting Scha ⁇ creates the shell. This means that a plastic deformation of the metallic matrix of the sheath less fails or even completely avoided.
- pseudo-plastic metallic particle In the use of pseudo-plastic metallic particle not behave this is similar to the metallic Comp ⁇ component, in which they are embedded. Both parts of the structure have similar moduli of elasticity in the order of magnitude. However, it is possible due to the pseudo-plastic behavior of the metal ⁇ metallic particles that these assume lung by a plantebehand- after deformation by a stone impact taking advantage of the so-called one-way effect of shape memory ⁇ alloys its original shape prior to deformation by the rockfall again ( Shape memory effect), where ⁇ can advantageously be healed again by injuries in the envelope by means of a heat treatment. The forces that arise during the recovery of the pseudo-plastic particles, also have a positive effect on the metallic matrix of the metallic component, which is thereby partly also re-deformed.
- the pseudo-plastic or pseudo-elastic behavior of the metallic particles which must be adjusted as a function of the alloy composition of the affected shape memory alloy, depends on the temperature of the wheelset shafts. It must be borne in mind that axles are operated ⁇ tur Scheme in a large temperature due to the atmo ⁇ spherical weather conditions. So it makes sense, for example, that the pseudo-plastic and / or pseudo-elastic behavior in a temperature range of Radsatzwellen from -20 to + 40 ° C is guaranteed (Central European Klimabe ⁇ conditions). It is possible that the phase transformation of the shape memory alloy is within this Temperaturbe ⁇ Reich, wherein the transition temperature is below a pseudo-plastic behavior and above this temperature is a pseudo-elastic behavior.
- the metallic component of the casing is coated with a pseudo-elastic or pseudo-plastic alloy. So on the one hand ensures that, as required by the invention, the metallic component forms the interface to the wheelset and thereby formed at most noble, as the metallic material of the wheelset, and on the other hand, a shape memory alloy can be used, which is above this metallic component and therefore does not come in di ⁇ direct contact with the material of the wheelset. This is important because shape memory alloys such as NiTi are generally nobler than the material of the wheelset shaft, and only in this way a risk of Radsatzwel ⁇ le by corrosion can be excluded.
- the pseudoelastic or pseudo-plastic alloy which thus forms the surface of the shell to the environment, according to the mechanisms already described can have a positive effect on the stone chip resistance of the shell and advantageously leads to a longer service life of the same.
- a separating layer of a less noble material is provided as the metallic material forming the interface of the wheelset or an electrochemically inert material.
- the separating layer can be applied to the shaft or in the interior of the casing, or separating layer and Um ⁇ sheathing are applied as a multi-layer on the wheelset. In any case, however, the separating layer is to be understood as part of the sheathing.
- the release layer be ⁇ works to improve the corrosion behavior between the Casing and the axle, wherein this difference can ⁇ Liche mechanisms are used.
- the separating layer consists of a metal that is less noble than the rest of the casing and the wheelset shaft, then this is, so to speak, to be understood as a sacrificial anode.
- a gap between the axle and the jacket produced in the region of the separating layer, however, the axle and the Ummante ⁇ development, at least not at first attacked by corrosion.
- This has the advantage that the function of both the wheelset shaft and the sheathing is completely retained. Only with advancing ⁇ tender corrosion can also be a corrosive attack of the shell done, which then still, if this is less noble than the material of the wheelset, a corrosion protection for the wheelset represents.
- an electrochemically inert material is, for example, plastic or an electrically non-conductive ceramic.
- an indicator layer of colored material is provided between the boundary surface of the wheel set shaft and the casing, which is permeable to moisture. Due to the moisture permeability causes the indicator layer does not galvanically separate the wheelset shaft from the rest of the shroud formed by the less noble material.
- the less noble material can serve in the manner already described as a sacrificial material in a corrosive attack in the gap, provided that the indicator layer itself is not less noble than the base material of me ⁇ metallic component.
- the indicator layer has a different function, namely the possibility to open by a simple visual inspection of the shroud, to ⁇ showing a breakdown of the sheath by rockfall in that the color of the indicator layer is considerate ⁇ bar from the outside. Therefore, the indicator layer should be at any corrosion processes in the gap between the sheathing and
- Wheelset not be involved so that it is still preserved after consumption of the sheath, and can indicate the color change.
- the already mentioned separating layer for the purpose of an indication of a breakdown of the sheath, if this has a characteristic color (advantage of functional integration).
- Wheelset be applied. Further particles can na ⁇ Moslich even after the application of the particles of the first type, that is, after production of the metallic component of the sheathing lung are applied.
- the method can be Kaltgassprit- zen also used to fill by rockfallassigeru ⁇ fene injuries in the casing again with the material of the sheathing.
- the cold gas spraying is particularly suitable, since this can also be carried out with portable devices that are equipped with so-called cold gas spray guns.
- the metallic component of the shell as the Grenzflä ⁇ surface of the axle is less noble forming metallic material and connected directly to the interface of the axle in elektrochemi ⁇ schem contact is, so are, for example as metal- lic component metals such as Al, Mg, Ti, Zn, Mn, V, Nb and their alloys, as far as these are also less noble than the Ma ⁇ TERIAL of the axle.
- the metallic component of the sheathing contains a light metal.
- This may be the main alloy component of an alloy, or this material may also be used purely as a metallic component.
- the use of a light metal has the advantage that by the sheathing, the total weight of the axle comparatively little increases.
- light metals in particular ⁇ special AI, Ti and their alloys come into question.
- FIG 1 shows an embodiment of the invention
- a wheel set shaft 11 is shown, which is connected to egg NEM wheel 12.
- a sheath 13 which may be of different construction, as will be described in the following figures.
- the sheath 13 is formed of a metallic component 14, are distributed in the pseudo-elastic particles 15 of NiTi. If a stone 16 strikes a region of the casing 13 which is protected by such a superelastic particle 15, this bounces off the casing 13 in the manner indicated by an arrow, without causing lasting damage.
- the metallic component 14 of the sheath 13 is formed from the ⁇ same steel as the axle 11. Therefore, intermediate of the axle 11 and the shell 13 see a direct contact possible since corrosion of the plane defined by the axle interface 17 for sheathing at least due to the formation of electrochemical local elements can be excluded.
- the sheath 13 consists of the metallic component 14 into which hard-material particles 18 are bound. These hard particles are capable of triggering two protective mechanisms upon the impact of a stone 16.
- the one (not shown) protection mechanism is that the less elastic hard material particles do not deform by the rockfall and thus the impressed by the stone ⁇ impacted load on a phase boundary 19 between the hard ⁇ material particles 18 and the metallic component 14, the metallic Matrix forms around the hard material particles 18, ver ⁇ shares.
- the second mechanism is ⁇ provides Darge also in FIG. 3 If the stone 16 has sufficient kinetic energy, the distribution of the joint does not extend beyond the hard material particles from ⁇ 18th
- the metallic component 14 is attacked, 20 hard material particles 18 are destroyed in the resulting crater. The destruction of the hard material particles into smaller ⁇ splitter 21 coming through a fraction of the particles reached, however, absorbs energy so that the Bela ⁇ tung the metallic component 14 is reduced by the destruction of the hard particles 18th
- the metallic component 14 is formed from a Aluminiumlegie ⁇ tion. This has the advantage that it is relatively easy.
- aluminum forms a passivation layer 23, which protects the surface 24 of the casing 13 from a weather-related corrosive attack. Since the passivation of aluminum occurs spontaneously, the formation of the passivation layer 23 after a rockfall is ensured, so that a corrosive attack in the formed crater can be avoided. This is of particular importance since the metallic component at Be ⁇ rich of the crater is already weakened.
- the metallic component 14, the highe ⁇ least is as noble as the material of the axle 11, designed as a relatively thin separating layer, which carries a further layer 25 made of NiTi.
- the sheath 13 is therefore designed as a multilayer layer.
- the layer 25 can, as one left Fault line 26 shown to be executed pseudo-elastic. This results in the event of falling rocks according to the attached ⁇ indicated arrow to a rebounding of the block 16. Is the La ⁇ ge 25 executed pseudo-plastic, so the stone 16 causes the formation of a crater 20. However, this injury can be the location 25 by subsequent Heat Treatment ⁇ lung heal, as the shape memory alloy "remembers" the original shape of the situation and so the old structure due to a phase transformation is restored.
- the cold gas spraying method illustrated in FIGS. 5 to 7 involves various applications of how this method for producing or repairing the sheaths 13 can be applied to the wheelset shafts 11.
- the sheath 13 consists of a sheath, which is bent around the wheelset shaft 11 (see dash-dotted contour of the sheath 13, which indicates a shape as it is present during the bending process). This results in a butt edge 27 of the envelope, come to rest on the opposite edges of the envelope together. To seal this edge or the resulting gap, the cold gas spraying is used.
- FIG. 6 shows how, by means of the cold gas spraying, the casing 13 itself is produced on the wheel set shaft 11.
- the wheel set shaft 11 is rotated slowly ge ⁇ , so that a relative movement between the cold gas jet 29 and the interface 17 of the wheelset 11 stands, at the same time an axial movement of the wheelset shaft can take place (not shown), which is dimensioned such that the coating of a helical line on the
- Interface 17 is generated. As a result, a closed casing 13 is formed, an intermediate stage of the coating process being illustrated in FIG.
- the cold gas spraying is used to heal injuries caused by rockfall 30 (in Figures 3 and 4 referred to as crater 20).
- the injuries caused by the particles of the metalli ⁇ rule component and possibly other particles are filled with Ausbil ⁇ dung of repair locations 31 single ⁇ Lich locally.
