Definitions
- the invention relates to a mounting for a vehicle driven through by a wheel load.
- an upper part receiving a rail section and indirectly or directly connected to a support, such as a rail fastening or ribbed plate, the upper part being mounted on the support side on a first elastic element and on the rail side having an at least one second elastic element which directly or indirectly prestressing the upper part with respect to the support
- Preloading device is arranged, and wherein the first and the second spring element each have a (first and second) characteristic curve, which form a spring system with an overall characteristic curve with a working range which is in the range of force application of conventional wheel loads.
- DE 30 33 607 C2 discloses a sound-absorbing rail support consisting of a base plate, a rail support plate and an element arranged between the base plate and the rail support plate.
- the rail support plate is provided between the base plate and the rail support plate at a lateral distance from the first insulating elements and is prestressed against the gamd plate and consists of abutments held by threaded bolts which and the base plate an elastically deformable biasing element is arranged.
- the design of the insulation elements and their arrangement result in a spring characteristic for the overall system formed from the insulation elements, which has an essentially constant slope. This means that there is a linear relationship between the spring travel and the application of force.
- the measures envisaged cannot always prevent the vibrations caused by a rail vehicle from being transmitted to the sleepers and the bedding in such a way that the latter can flow, in particular, if appropriate rail supports are used in high-speed lines.
- the entire superstructure is always the same "hard” or “soft” depending on the spring characteristics of the insulation elements used.
- the latter is particularly disadvantageous if construction work on the upper or lower structure is required.
- the problem underlying the present invention is to develop a mounting of the type described above in such a way that, depending on the forces introduced, optimal conditions arise as a function of the elasticity, so that e.g. when straightening and tamping a track, the superstructure represents a rigid unit, whereas when driving through rail vehicles there is an elasticity that enables strong damping.
- the problem is solved according to the invention in that the overall characteristic of the spring system has a kinked course such that when the force applied to the spring system is less than the forces acting in the working area, the characteristic curve rises steeply and runs flat in the work area.
- a spring system is proposed that is hard at low loads and is dynamically soft in a selectable area (working area).
- the former means that the superstructure presents itself as a rigid unit if e.g. Work such as straightening and plugging the rails are required.
- the overall characteristic line of the spring system according to the invention can be designed such that the total spring travel of the spring system at a force application between 0 and 50 kN is less than 0.5 mm, with a linear relationship between force and spring travel in this steep area of the characteristic curve.
- the characteristic shows a flat course, through which the desired damping takes place.
- this flat area too, there should be a linear relationship between force and travel.
- the spring travel covered can be approximately 2.5 mm when the applied force changes from 50 kN to 100 kN.
- the overall characteristic curve according to the invention consequently shows a low spring stiffness in the working area, that is to say in the area in which the usual wheel loads are introduced, so it can dampen strongly, whereas a statically hard system is present in front of the working area.
- This so-called kinked overall characteristic results in particular from the fact that the pretensioning device receives the second spring element in such a way that it is compressed on all sides with a force, namely with a force that is in front of the Work area.
- the second spring element has a low spring stiffness, which essentially determine the dynamically soft properties of the overall system.
- the first spring element itself has a characteristic which is steeper with respect to the elastic region of the second spring element.
- the second, ie upper, spring element in the non-working area of the overall system is to be regarded as tightened to a block, and is therefore located in the hard area.
- the second spring element goes directly into its elastic range when the overall system is in the work area, since the wheel load relaxes in such a way that the second spring element is no longer compressed on all sides. can exert its spring properties.
- the overall characteristic curve results from the subtraction of the individual forces acting as a function of the respective force application and the resulting spring travel.
- the second spring element can be designed as at least one projection directed away from the superstructure, which extends within a receptacle of the pretensioning device, the volume of the receptacle being equal to or slightly smaller than that of the projection.
- a further proposal of the invention provides that the projection of a flat, parallel to the upper Surface of the upper component, preferably extends along from this extending third spring element.
- the second and third spring elements accordingly form a unit of their own, from which a characteristic curve results, in which the section of the characteristic curve that normally runs parallel to the ordinate in the compression region of the second spring element is slightly inclined.
- the second spring element can have a plurality of projections which are covered by a cover having receptacles associated with the Voi jumps, which in turn is connected to the support via connecting means and can be tightened relative to the latter in order to achieve the necessary pretension.
- the upper component is a rail fastening plate such as a rib plate
- this can extend at least in sections within the first spring element in the form of an elastic intermediate layer.
- the first spring element can thus be vulcanized onto the rail fastening plate.
- the projections of the second spring element can be dome-shaped and have the shape of a cylinder or truncated cone.
- Fig. 1 shows a schematic diagram of individual characteristics to form a
- Fig. 2 shows a section through a recorded by a spring system
- FIG. 3 is an exploded view of the right part of FIG.
- Fig. 4 is a plan view of an arrangement corresponding to FIG. 2.
- the figures show a bearing and its characteristic curve for an upper component in the form of a ribbed plate (10) on which a rail (not shown) can be fastened in the usual way.
- the ribbed plate can be supported in relation to a support such as a threshold in such a way that, on the one hand, a statically hard unit of the superstructure results when force is applied, which is lower than usual wheel loads, and on the other hand a dynamically soft unit results when normal wheel loads act sufficiently to vibrate to be able to dampen, the ribbed plate (10) is received by a spring system below and supported against the support, resulting in a characteristic curve which is shown in FIG. 1 at the bottom right.
- the characteristic curve provided with the reference symbol (12) has a steep rise (14) which merges into a plateau-like section (16) which rises gently and corresponds to conventional wheel loads in relation to the forces P introduced.
- the working range (16) extends from this value to approximately 100 kN. Above the working range, the characteristic curve of the overall spring system is essentially of no interest, so that it is also not shown.
- the invention provides that a first spring element in the form of an elastic intermediate or underlay (18) is arranged between the eyelet plate and the support (not shown) such as a threshold.
- the intermediate layer (18) can be vulcanized onto the ribbed plate (10) and cover it at least in sections along its longitudinal edges.
- the first spring element or the intermediate layer (18) has a characteristic curve which is shown at the top right in FIG. 1 and is provided with the reference symbol (20). It can be seen that the intermediate or underlay (18) has a linear characteristic curve, i.e. that the introduction of force and spring travel are proportional to one another.
- a second spring element is arranged above the rib plate (10) and, in the exemplary embodiment, is composed of two dome-like projections (22), (24) in the shape of a truncated cone.
- the second spring elements (22) and (24) have a characteristic curve, which is shown at the top left in FIG. 1, to the extent that it concerns the gently rising region (26), which is further drawn with dashed lines.
- the second spring element (22) or (24) and thus the system including the ribbed plate (10) and the base (18) is pretensioned relative to the threshold in such a way that an overall course (28) consisting of the flat section (26) and a steeply rising section (30).
- This section (30) is achieved by prestressing the spring element (22) or (24) in such a way that it is compressed on all sides.
- the spring element (22) can no longer have spring properties in the actual sense, so that the steep section (30) results, which should ideally be parallel to the ordinate (force P).
- the clamping plate (36) is tightened by means of a fastening element (not shown) such as a bolt in relation to the support and thus in the direction of the rib plate (10), the spring element (22) is deformed in such a way that the receptacle or the cavity (32) is completely filled, so that further compression is no longer possible.
- a fastening element such as a bolt
- the spring element (22) is deformed in such a way that the receptacle or the cavity (32) is completely filled, so that further compression is no longer possible.
- the prerequisite for this is that the volume of the receptacle (32), (34) is equal to or slightly less than the volume of the dome-like voi jumps (22), (24).
- This preload results in an overall spring system consisting of the first spring element (18), ie the base, and the second spring element (22), (24), ie the projections, which now has the characteristic curve (12) according to FIG. 1 owns.
- the characteristic curve of the prestressed second spring elements (22) and (24) is selected such that the steeply rising area (14) of the overall characteristic curve lies in front of the actual working area in which the rail fastened to the ribbed plate is passed, that is to say usual wheel loads act.
- the overall characteristic can be obtained as follows:
- the projection (24) is shown in the relaxed state.
- the receptacle (34) can be seen in section to make it clear that the volumes of the projection (24) and the receptacle (34) are coordinated with one another in such a way that all-round compression can take place, as a result of which the projection (24) no longer exhibits spring properties is as stiff as a stop.
- the base (18) and the rib plate (10) are penetrated by a bushing (38) which can form a unit with the base (18) and the rib plate (10).
- the bushing (38) continues in a sleeve-like stiffened section (40) in the clamping plate (36).
- the dimensions of the sleeve and the bushing (38) are coordinated with one another in such a way that the clamping plate (36) is tightened in such a way that the desired characteristic curve (12) is obtained, that is to say the pretensioning does not result in a force which impermissibly influences the effect of the overall Fecler system ⁇ leads.
- the tensioning plate (36) In order to prevent the tensioning plate (36) from striking when the above-mentioned relief occurs when a rail vehicle is being driven through, the tensioning plate is supported on a plate (42) which can be referred to as a third spring element and which has a high degree of spring stiffness.
- the third spring element (42) also has the effect that the section (30) of the characteristic (28) does not run parallel to the ordinate, but inclined to it.
- the materials for the spring elements (18), (22), (24) and optionally (42) can be customary rubber mixtures, polyurethane or others which are suitable for elastomer springs.
- the materials of the first spring element (18) and of the second spring element (22), (24) can be the same, so that the desired spring characteristic is determined solely by the shape or material hardness.
- rib plate (10) is shown again purely schematically with the spring system according to the invention which supports it in relation to the threshold (not shown).
- the clamping plates (36) and (44) running in the respective edge area can be seen. which can be connected with bolts (46) or (48) to the support of the sleeper and tightened against it.
- the projections (22), (24) and (50), (52) which are outside the Work area over the clamping plates (36) and (44) are biased so that they are in their compression area, so have the effect of a stop.
