Definitions

  • the invention relates to a sleeve buffer for movable or fixed support structures according to the preamble of claim 1.
  • a so-called absorber buffer in which a sleeve is provided in a recess in a fastening plate for fastening to the support structure.
  • cutting tools are provided which are attached to the fastening plate and act on the sleeve.
  • the prior art discloses the FR 2 789 358 A1 Sleeve buffers, which also have consumable elements and tools that machine them, for the purpose of dissipating energy when the normal operational forces are exceeded. These consumable elements and the tools that machine them if necessary are each arranged recessed in an immersion opening in the support structure, on which the sleeve buffer is mounted on the outside.
  • the FR 2 775 240 A1 discloses sleeve buffers, with guide and deformation structures that deform when the normal operational forces are exceeded, as well as penetration openings in the relevant support structures, into which the sleeve buffer can immerse in accordance with the length of the guide and deformation structures reduced by the deformation to compensate for the length.
  • the EP 1 740 435 A0 also discloses sleeve buffers, with structures that deform or break at predetermined breaking points when the normal operational forces are exceeded.
  • the object of the invention is to be able to provide a sleeve buffer that can be used as universally as possible for support structures of different types and with different requirements and still offers a high level of safety.
  • the task is, based on a sleeve buffer of the type mentioned, solved by the characterizing features of claim 1.
  • the invention relates to a sleeve buffer for movable or fixed support structures, in particular rail vehicles.
  • a fixed support structure is, for example, a buffer block that represents the end of a track and is intended to prevent a rail vehicle from rolling beyond this area and possibly derailing.
  • Movable support structures are usually rail vehicles such as locomotives, freight cars, passenger cars or the like.
  • the sleeve buffer according to the invention is telescopic and comprises a first and a second guide part in the form of a sleeve and a plunger, and optionally also several guide parts.
  • the sleeve and plunger have different diameters so that they can be pushed into one another in the event of an impact, i.e. they are telescopic.
  • the sleeve can be fixed in place on a support structure.
  • the relative displacement between sleeve and plunger during the telescoping movement occurs accordingly in the longitudinal direction of the vehicle.
  • the corresponding sleeve buffers are often referred to as side buffers due to their arrangement on the (vehicle) support structure.
  • a structure forming a mechanical resistance is provided in order to brake the telescoping movement during the telescoping movement of the guide parts and/or the elongated sections.
  • Such mechanical resistance to energy dissipation offers several advantages.
  • the mechanical resistance is used in a telescoping sleeve buffer, in such a way that the telescoping movement is also inhibited.
  • diving into the support structure can be avoided.
  • a mechanical resistance can be chosen so that it allows scalability, so that use on different rail vehicles or support structures of different sizes can be made possible.
  • a mechanical resistance can be provided which hinders telescoping movement between the first and second guide parts when the triggering force is exceeded.
  • the telescoping movement of the elongated sections of a guide part can also be braked once the triggering force has been reached.
  • cutting tools can be considered as structures forming mechanical resistance.
  • these tools When the triggering force is exceeded, these tools are brought into contact with a structure of the sleeve buffer, so that the structure of the sleeve buffer is damaged as a result of the impact effect. If the energy during the impact is sufficient, the cutting tool is pushed forward and its machining process consumes part of the energy.
  • This embodiment has in particular the The advantage is that very good scalability is possible.
  • the area over which the tool engages in the structure during machining can be selected.
  • the penetration depth can also be varied.
  • a plastically deformable barrier in particular a web or a bolt, which is arranged as an obstacle in the path of the guide part or elongated section to be deformed during the telescopic movement can also be considered as mechanical resistance.
  • the mechanical resistance may correlate with the thickness of the component to be deformed or with regard to the material selection for the barrier.
  • the bolt can also be made of a special material to adjust the resistance. Consequently, a certain scalability is enabled.
  • the scaling can also be adjusted by providing multiple bolts to increase resistance.
  • the structure forming a mechanical resistance can be arranged so that during telescoping movements of the elongated sections, the cutting tool or tools perform machining perform/carry out one of the elongated sections.
  • the elongated sections are generally only moved relative to one another when the triggering force is exceeded, in that the elongated sections are connected to one another via predetermined breaking connections, which only break when the triggering force is reached. The machining can then take place.
  • the cutting tool can also be arranged on one of the guide parts in such a way that it processes the other guide part when the triggering force is exceeded.
  • the tool is arranged on the ram and processes the sleeve.
  • This embodiment of the invention can have the advantage over the variant in which an elongated section is machined that no section is affected in its structure, which is constantly in the flow of force for support. For example, if the plunger is divided into several elongated sections, these can support each other until a certain force is reached.
  • a spring that is in the flow of force is often supported on one of the elongated sections. If the structure of an elongated section is impaired by machining, the flow of force can be impaired if the structure breaks, for example.
  • the structure forming a mechanical resistance can also be arranged in such a way that it engages with a guide part or one of the elongated sections, ie there is a mechanical coupling between the parts, which only leads to a plastic deformation when the triggering force is exceeded. It is also conceivable that the structure forming mechanical resistance is mounted in such a way that a certain freedom of movement is still possible (support with play is provided) and energy consumption can only take place from a certain trigger force or with a certain deflection / telescoping movement. This can advantageously support the fact that a certain degree of elasticity must be provided; As part of the normal buffer stroke, no machining takes place and the tool can move freely in the storage. The tool only engages with a structure once the triggering force has been reached.
  • the inner or outer casing of a guide part or elongated section When telescoping, it may be possible, for example, for the inner or outer casing of a guide part or elongated section to be machined. Machining the inner casing generally has the advantage that no chips fly away due to the high speed and may pose a danger to people in the area or damage objects in the area.
  • the sleeve buffer according to the invention comprises at least two guide parts, a plunger and a sleeve. So that they can be telescoped into one another, the inside diameter of one of the guide parts is larger than the outside diameter of the other guide part. In particular, the inside diameter of the sleeve is larger than the outside diameter of the plunger, so that it can be inserted into the sleeve.
  • the internal guide part with a smaller diameter can also be constructed from elongated sections arranged one behind the other.
  • the outer guide part consists of elongated parts arranged one behind the other sections. If the triggering force is now exceeded, various scenarios are conceivable.
  • the selected geometries can be dimensioned such that in the course of the displacement movement of the plunger, the predetermined breaking connections are torn off first. Following this, for example, deformations of other structures such as a deformation of the sleeve, a bolt, a deformation by a tool or the like can be provided for additional energy consumption.
  • individual elongated sections are pushed telescopically into one another, they preferably have a cylindrical shape, which is also advantageous for absorbing transverse forces and has a comparatively high bending moment.
  • Telescopically movable elongated sections which are connected via predetermined breaking connections, can be viewed as a one-piece component or guide part.
  • the inside diameter of the space into which the section is pushed is, from a certain point, smaller than the outside diameter of the section to be moved.
  • Deformation is also necessary here during the telescopic movement in order to completely push the components into one another. This results in energy consumption.
  • such an embodiment can be manufactured comparatively simply by strengthening the wall or simply making it thicker.
  • a comparatively high energy consumption is made possible.
  • one of the elongated sections is provided with recesses or slots so that controlled deformation can take place more easily and in a more targeted manner.
  • the force transmission member is always in the flow of force during the telescopic movement, even if the triggering force is exceeded.
  • the force transmission member which can be designed in particular as a spring, can always absorb and store a certain amount of energy (elastic pushing together of the buffer during normal buffer stroke). In a (partially) inelastic collision, energy is consumed, for example as a result of deformation or as thermal energy.
  • the force transmission member ensures a certain level of support between the buffer plate, to which a force is transmitted during an impact, and the support structure.
  • a mechanical coupling in the longitudinal direction between elongated sections or a coupling to one of the guide parts can continue to exist even after the predetermined breaking connections have been torn off.
  • the elongated sections can slide past each other, but the guide points are in mechanical contact with one another in such a way that there is increased friction, which results in further energy consumption.
  • the sections can, for example, have projections that come into contact with the inner walls.
  • the cutting tool can be designed as a ring which includes at least one cutting edge, the ring in particular being not connected insert is stored or floating.
  • the ring can therefore be manufactured as a separate component and it is not necessary to integrate the cutting tools in one of the sections or one of the guide parts.
  • the guide part can be designed in such a way that after the triggering force has been exceeded, it is shortened by controlled deformation under a high, essentially constant force. This means that energy consumption can take place in a comparatively controlled form. In principle, the course of events in the event of a collision is difficult to predict; Nevertheless, the framework conditions can be created in order to at least achieve energy consumption that is as consistent as possible.
  • Figure 1 shows a sleeve buffer 1 with a plunger 2 and a sleeve 3, the plunger 2 being mounted as the first guide part in the sleeve 3 as the second guide part.
  • the plunger 2 is partially accommodated in the sleeve 3, with both guide parts 2, 3 overlapping over a certain coverage length 4.
  • This overlap 4 means, among other things, that any transverse forces that may occur in the event of an impact can be absorbed.
  • the sleeve 3 in turn is firmly connected to the support structure 5.
  • the plunger 2 ends with a ring 6, which is provided with cutting tools 7.
  • the tools 7 are arranged on the circumference of the ring 6.
  • the floating ring is in contact with an elongated section 8 in which a spring 9 is mounted.
  • This spring 9 is permanently in the flow of force: If a force acts on the buffer plate 10 as a result of a shock, the plunger 2 connected to the buffer plate 10 presses on the ring 6 and in turn transmits a force to the section 8 and thus also to the spring 9 , which in turn is supported on the support structure 5. As long as the tools 7 do not reach the bolts 11 when the sleeve buffer 1 is compressed, which does not occur in the area of the normal buffer stroke, the shock can be absorbed essentially elastically via the spring 9 alone. After the force is lifted, the plunger 2 is pushed away from the support structure 5 again and reaches its original position.
  • the sleeve 3 is provided with a recess 12 in the area of the tools 7, so that the tools 7 are mounted with play in this area and can be moved in the direction of the longitudinal axis without machining.
  • the sleeve 3 is in the area 3a are also thicker, so that the tools 7 cut into the material of the sleeve 3 in the area 3a after the bolt 11 has been separated or shielded. From this point onwards, the intended energy consumption takes place.
  • the section 8 is provided with projections 13 so that these can guide the section in the areas 3a since they rest on the inner wall.
  • the ring 6 can also be designed in such a way that a certain force is sufficient to cause the section 8 to break through the ring 6. This measure also results in further energy consumption.
  • the plunger 2 is designed in the area 2a so that its inner diameter tapers. If section 8 hits this area, it experiences further mechanical resistance, which contributes to energy dissipation.
  • the sleeve buffers 21, 31 according to Figures 2 , 3 are equipped with predetermined breaking connections S.
  • a sleeve buffer 31 is sketched, which differs from the variant according to Figure 2 the extension sleeve 38 is processed as an elongated section and thus, in addition to a breakage of the predetermined breaking connections S when the triggering force is exceeded, leads to energy consumption.
  • the tools 37 are also attached to the plunger 32, but on its inner surface so that they can hit the extension sleeve 38.
  • the sleeve 33 which is firmly connected to the support structure 35, is not machined.
  • the spring 39 is practically permanently in the flow of force when the sleeve buffer 31 is subjected to a force via the buffer plate T.
