Definitions
- the invention relates to an articulated coupling for rail vehicles, in which a coupling tab is mounted by means of a spherical bearing in a clutch fork.
- An articulated coupling of the type mentioned is known for example from US 5,172,819 A.
- This is a coupling for semi-permanent connection of wagons.
- units of ten cars are assembled, which are usually separated only for maintenance purposes.
- the semi-permanent connections between the wagons should help to reduce the impact of impact forces acting on a wagon under the impact conditions of train operation.
- the object of the invention is to specify a joint coupling which is suitable for rail vehicles and which is distinguished both by a design which is commensurate with the claim and by a particularly rational manufacturability.
- This joint coupling has an engaging in a coupling fork coupling tab with a spherical bearing, said coupling fork and coupling tab are also referred to as a mother part or father part.
- Parts of the spherical bearing are an inner ring having a convex surface and a co-operating, sliding bearing outer ring having a concave surface secured in an opening of the coupling tab.
- both the outer ring and the coupling tab each have a groove, wherein a clamping ring rests in the groove of the outer ring and at the same time in the groove of Kupplungsla- see.
- the clamping ring is slotted axially as a one-piece metal part; Alternatively, several individual clamping ring segments can be used.
- the attachment of the outer ring in the coupling tab by means of clamping ring on the one hand has the advantage of a simple installation, on the other hand, given no restrictions on the materials due to the elimination of welding.
- a blasted outer ring is usable.
- a small compared to the outer ring and the coupling tab width of the clamping ring allows large-scale investment of the outer ring in the opening of the coupling plate and thus a particularly uniform force application.
- the width of the clamping ring measured in the axial direction is less than 15%, in particular less than 10%, of the width of the outer ring measured in the same direction. The latter width is preferably consistent with the width of the coupling tab.
- the coupling tab has bores which extend from the circumference of the coupling tab to the groove of the coupling tab. These holes serve to receive screws with which the radial Positioning of the clamping ring can be changed at least in sections. In this case, both an increase and a reduction of the radius of the clamping ring come into consideration.
- the clamping ring forming part of the joint coupling is preferably located completely in the groove of the coupling lug.
- the clamping ring is elastically biased so that it rests completely in the groove of the coupling tab, as long as no further forces acting on him. In this positioning of the clamping ring a very simple insertion of the outer ring in the opening of the coupling tab is possible. In order subsequently to connect the clamping ring to the outer ring in a form-fitting manner, only the screws located in the bores have to be tightened, which in this case exert a force on the clamping ring radially inwards.
- an end-side screwing of the clamping ring can be provided.
- the advantage of such a screw with screws, which are arranged parallel to the axial direction of the clamping ring and the outer and inner ring can, depending on the geometric conditions in the individual case, in particular lie in a favorable stress distribution, the position of a neutral fiber is utilized.
- a combination of radial and axial arrangement of clamping screws acting directly or indirectly on the clamping ring is also possible.
- the screws which are provided for pressing the clamping ring in the groove of the outer ring can be secured for example by gluing against loosening.
- a clip made of steel is preferably placed around the openings in the coupling tab as a safeguard against unscrewing of the screws, wherein an attachment on one or symmetrically on both sides can be provided.
- the clamping ring has in an advantageous embodiment in cross-section on a radially inwardly directed, at least one-sided taper.
- the taper is bilaterally, symmetrically to a clamping ring and possibly the radial holes intersecting plane formed.
- the groove in the outer ring has a cross section of the clamping ring adapted, radially inwardly tapering cross section, so that the clamping ring is positionable in the outer ring without play.
- the game of the clamping ring in the groove of the coupling tab preferably remains in completely assembled joint coupling.
- two clamping rings arranged in parallel planes are positioned between the outer ring and the coupling lug.
- the outer surface of the outer ring and the surface of the opening of the coupling tab can be designed to be cylindrical throughout.
- the axial fixing of the outer ring relative to the coupling tab takes place exclusively via the clamping rings.
- the flange of the coupling tab or the outer ring preferably has a bevelled, abutting on the other component edge.
- the end face of the flange integrally formed on one of the components, in particular the outer ring, is preferably aligned with the front-side surface of the other component, in particular the coupling lug.
- Figure 1 in cross section a first embodiment of a
- FIG. 2 in cross-section detail a second embodiment of a universal joint for rail vehicles
- FIG. 3 shows in a view analogous to FIG. 2 a third exemplary embodiment of an articulated coupling for rail vehicles.
- the universal joint 1 shows in simplified form an articulated coupling 1 for rail vehicles, whose principal function is known, for example, from DE 103 60 289 A1.
- the universal joint 1 for example, for couplings with tie rods, as described in DE 195 43 183 A1.
- Another application for the universal joint 1 is the coupling of ends of two articulated vehicle units supported on a common bogie, as basically described in EP 0 520 301 A1.
- the universal joint 1 has a spherical bearing 2, by means of which a coupling tab 3 is connected to a coupling fork 4.
- a game of the universal joint 1 in a first direction is denoted by x; Furthermore, a game exists in a direction orthogonal thereto. Depending on the installation position of the universal joint 1, the game x may be the vertical game or the horizontal game.
- the bearing 2 is designed as a sliding bearing, wherein an inner ring 5 is pivotally mounted with a spherical surface 6 in an outer ring 7 with a concave surface 8.
- the inner ring 5 is penetrated by a pin 9, which is held in holes 10 which are located in fork cheeks 11, 12 of the clutch fork 4.
- the holes 10 are to prevent displacement of the bolt 9, covered with flaps 13.
- the outer ring 7 Before assembly of the universal joint 1, the outer ring 7 is blown up by forces acting in the radial direction. This has the advantage that the outer ring 7 along a plane E, which forms a normal to the axis of symmetry A of the spherical bearing 2 arranged symmetry plane of this bearing 2 need not be divided.
- the constructed as a blasted outer ring outer ring 7 is inserted into a cylindrical opening 14 of the coupling plate 3. Details of the attachment of the outer ring 7 in the opening 14 of the coupling tab 3 will be apparent in particular with reference to Figures 2 and 3, the embodiments of articulated couplings 1 show, the basic structure corresponds to the embodiment of Figure 1.
- a groove 17 on the outer, substantially cylindrical surface 16 of the outer ring 7 is opposite to a groove 15 in the wall 18 of the opening 14.
- the matching, measured in the axial direction width b of the grooves 15, 17 is about 10% of the width B of the coupling plate 3 and the outer ring 7.
- the clamping ring 18 is slotted axially, so that the diameter of the clamping ring 18 can be varied by acting on these forces. If the outer ring 7 is in the final, illustrated position during the assembly of the universal joint 1 relative to the coupling lug 3, the diameter of the clamping ring 18 will be penetrated by means of individual screws 19 each penetrating a radially arranged bore 20 in the coupling lug 3, decreases, so that the clamping ring 18 partially engages in the groove 17 of the outer ring 7. The screws 19 are secured by a steel clamp 21 against unscrewing.
- the coupling tab 3 penetrating bore 20 is formed as a threaded bore 22 which has a diameter which falls slightly below the constant width b of the groove 15 of the coupling tab 3.
- the groove 17 of the outer ring 7 has a radially inwardly on one side ( Figure 3) or two-sided ( Figure 2) conically extending shape, which is adapted to a taper 23 of the clamping ring 18.
- Figure 3 a radially inwardly on one side
- Figure 2 two-sided
- a single clamping ring 18 is sufficient, while only one side Anschrä- supply of the clamping ring 18 according to FIG 3 preferably two clamping rings 18 between the coupling plate 3 and the outer ring 7 are stretched.
- a flange 24 is formed on the outer ring 7, as visible in Figure 3. This has a chamfered edge 25 which bears against the coupling tab 3.
- the outer ring 7 and the coupling plate 3 has a matching width B.
- a pivot angle of the bolt 9 relative to the outer ring 7 is indicated by ⁇ .
