Definitions

• the invention relates to an arrangement for fastening a component for energy absorption on a rail or road vehicle, the component being fixable on the vehicle via an intermediate element connected thereto for receiving impact energy acting on the vehicle in the longitudinal axis of the vehicle.
• the passenger cells When a moving train composition collides with one another, the passenger cells should not be subjected to high accelerations and should be deformed as little as possible. At average impact speeds in the order of up to about 60 km / h, a substantial part of the energy released in a collision can be absorbed by a special construction of an intermediate element connecting the coupling to the car. To this end, it is known to support the clutch via crash tubes or interposed honeycomb packets on a cross member to absorb the impact energy acting on the vehicle in the longitudinal axis of the clutch or vehicle. In addition to a clutch, there are other components that are used for energy absorption in the vehicle's longitudinal axis, e.g. Buffer or anti-climber.
• the invention is therefore based on the object of providing an arrangement for fastening a component of the type mentioned at the outset, which is simply set and, after a collision, is repaired with little effort, i.e. can be restored with few replacement parts.
• the arrangement should have a reduced space requirement compared to conventional solutions according to the prior art.
• the intermediate element consists of at least two frictionally connected and after overcoming the the forces causing frictional engagement with energy absorption in the longitudinal axis of the vehicle are displaceable partial elements.
• the solution according to the invention namely to absorb the impact energy by means of a slidable component attachment with high friction resistance, leads to a construction which is subject to wear only in the area of friction in the event of an impact and in particular does not lead to deformations which make it necessary to replace the entire intermediate element .
• bores are provided in a first sub-element and undercut grooves running in the longitudinal axis of the vehicle in a second sub-element, screws penetrating the bores and forming a clamp connection by screwing with counter-members mounted in the grooves.
• the bores are preferably arranged in at least one row, and the counterparts are designed as threaded strips guided in the undercut grooves.
• the intermediate element comprises a receiving tube fastened to the vehicle with a component support for holding the component which is held in a frictionally locking manner and can be displaced in the longitudinal axis of the vehicle after the frictional forces have been overcome.
• the receiving tube is preferably integrated into the vehicle floor via profile connections and welded to it.
• a head plate can be provided on the component support for releasably fastening the component. For manufacturing reasons, it can also be advantageous to To provide component support in the longitudinal axis of the vehicle and to connect the two support parts via the head plate.
• the sub-elements of the arrangement according to the invention are preferably made of extruded profiles made of an aluminum alloy, insofar as this is technically feasible and useful.
• Figure 1 is a side view of a coupling receptacle integrated in a vehicle floor with a guide tube.
• Fig. 2 is a bottom view of the arrangement of Fig. 1;
• Fig. 3 is an oblique view of the underside of the coupling receptacle of Fig. 1;
• Fig. 5 is a top view of the coupling support of Fig. 4;
• Fig. 6 is an oblique view of the clutch support of Fig. 4;
• FIGS. 7-9 show the views corresponding to FIGS. 4 to 6 for the right-hand part of a split clutch support
• FIG. 10 shows a cross section through a coupling receptacle with a guide tube
• FIG. 11 shows a cross section through a guide tube with inserted coupling support looking in the direction of the inside of the head plate.
• a coupling receptacle 10 shown in FIGS. 1 to 3 is integrated in a car floor 12 of a rail vehicle, not shown in the drawing, which is only hinted at in the drawing.
• the coupling receptacle 10 comprises longitudinal profiles 16, 18 which are welded at one end to a cross member 20.
• the coupling receptacle 10 is installed in the vehicle floor 12 as an integrating element via profile connections 21 which face the corresponding profile parts of the vehicle floor and are welded to them.
• a guide tube 14 projecting downward from the vehicle floor level, is inserted in the coupling or vehicle longitudinal axis x.
• the guide tube 14 has an essentially rectangular opening cross section and is composed of individual extruded profiles P which are connected to one another via weld seams S to form side walls 22, base 24 and top wall 25.
• the closed cross-section of the guide tube 14 is limited to the area of the coupling-side end 26.
• the side walls 22 run obliquely upwards against the coupling end 28, and the bottom 24 is largely open through a recess 30 towards the coupling end 28. Due to the special design of the side walls 22 and the recess 30 in the bottom 24, the inside of the guide tube 14 is largely freely accessible from the end 28 remote from the coupling.
• Coupling longitudinal axis x extending undercut grooves 32, 34, 36 are formed.
• the guide tube 14 serves to accommodate a coupling support, which is designed in two parts in the present example and on which the car coupling is later fixed.
• a left support part 38 shown in FIGS. 4 to 6 has a side wall
• the side wall 42 of the coupling support also runs obliquely upwards against the end 54 remote from the coupling and the bottom 46 has a recess 48 which is approximately the recess 30 in the bottom 24 of the guide tube 14 corresponds.
• a reinforcing web 50 running in the longitudinal axis x of the coupling is provided to reinforce the side wall 42.
• a head plate 56 is welded onto the coupling-side end 52 of the left support part 38, on the back of which threaded inserts 58 are fixed by means of screws 60. These threaded inserts 58 provide threads 62 for screwing on a car coupling, not shown in the drawing.
• Bores 64 are arranged in the side wall 42 and in the top wall 44; these form rows 66, 68, 70 extending in the longitudinal axis x of the coupling.
• a right support part 40 is shown in FIGS. 7 to 9.
• the support parts 38 and 40 are mirror images of each other and complement each other to form the actual clutch support. To simplify matters, the same details of the two support parts 38, 40 are provided with the same reference numbers.
• the coupling support consisting of the support parts 38, 40 is built into the guide tube 14.
• the rows 66, 68, 70 of bores 64 arranged in the side wall 42 and the top wall 44 of the two support parts 38, 40 are each one of the undercut grooves 32, 34, 36 formed on the side walls 22 and on the top wall 25 across from.
• Screws 74 inserted into the bores 64 are screwed together with threaded strips 72 inserted into the grooves 32, 34, 36. It goes without saying that the threads arranged in the threaded strips 72 have the same spacing as the bores 64 within the rows 66, 68, 70.
• individual sliding blocks can also be used as clamping plates.
• the screwing of the support parts 38, 40 to the guide tube 14 can be carried out without problems due to the special design of the side walls 22, 42 and the recesses 30, 48 in the base 24 or 46 due to the free access from the end 28 or 54 remote from the coupling.
