Definitions

  • This invention relates to a rail-mounted car that comprises two chassis, which are permanently connected via a link device, which comprises two link members connected to a chassis each, which members are turnably connected to each other via a hinge.
  • the invention relates to a link device as such intended for permanently connecting two car chassis.
  • Link devices or link couplings for permanently connecting two chassis or car bodies included in a rail-mounted car or railroad car are richly described in the patent literature. See, for instance, US-A-2 051 958 , US-A-3 667 820 , DE-A-1 094 289 , DE-AS-1 605 188 , DE-19638763A1 , DE-4121080A1 , DE-10153460A1 , FR-A-2 398 651 , EP-A-0279245 , EP-A-0343482 , EP0771710A1 and EP1312527B1 .
  • the hinge that connects the two link members in couplings of the kind in question has the purpose of, between the link members, transferring intermittent tensile, compressive and torsion stresses of the type that arise under all the conditions that occur in driving train units at low as well as high speeds, i.e., allowing all types of translations and rotations irrespective of these acting in the longitudinal, lateral or vertical direction, e.g., upon cornering and in driving in hilly topography, respectively.
  • the hinge has to be made with a vertical pin in order to enable horizontal turning laterally, as well as a more sophisticated, spherical bearing in which an elastic impact- and vibration-absorbing body (elastomer body) is included, and which can absorb the translations and rotations of the link members.
  • Such link couplings are permanent in the sense that they essentially have the purpose of permanently holding together two or more wheel-carried chassis or car bodies that together form an individual car, which in turn may be connected to and disconnected from other cars.
  • the chassis in one and the same car are permanently connected to each other.
  • EP 1 312 527 discloses a link device for a rail car comprising two chassis which are permanently connected via the link device.
  • a first link member connected to a first car chassis is hinged to a second link member connected to a second car chassis.
  • the hinge For disconnection of the car chassis, either the hinge must be opened, or any of the link members must be dismounted from its associated car chassis. Either of these operations involves the problems discussed above.
  • US 4,962,861 disclose an articulated connector for joining together two rail car platforms which are supported on a common truck bolster.
  • a hinged drawbar connection between connector portions requires dismounting.
  • the connector portions are rigidly secured to the rail car chassis such as by welding.
  • EP 1 151 905 discloses an articulated connection between links secured by bolts to the chassis of two interconnected rail cars which requires, in order for separation of the rail cars, that either the articulated connection be opened and dismounted, or the links be dismounted from the rail car chassis.
  • EP 1 312 527 discloses a link device for a rail car comprising two chassis which are permanently connected via the link device.
  • a first link member connected to a first car chassis is hinged to a second link member connected to a second car chassis.
  • the hinge For disconnection of the car chassis, either the hinge must be opened, or any of the link members must be dismounted from its associated car chassis. Either of these operations involves the problems discussed above.
  • US 4,962,861 disclose an articulated connector for joining together two rail car platforms which are supported on a common truck bolster.
  • a hinged drawbar connection between connector portions requires dismounting.
  • the connector portions are rigidly secured to the rail car chassis such as by welding.
  • EP 1 151 905 discloses an articulated connection between links secured by bolts to the chassis of two interconnected rail cars which requires, in order for separation of the rail cars, that either the articulated connection be opened and dismounted, or the links be dismounted from the rail car chassis.
  • a primary object of the invention is to provide a link coupling that enables disconnection and connection, respectively, of two chassis included in a car without having to dismount and remount, respectively, the hinge between the two link members of the coupling, or dismounting and remounting, respectively, anyone of the fixings of the link members against a chassis; all with the purpose of enabling a quick and simple disconnection and connection, respectively, of two car chassis, e.g., in connection with intermittently occurring repair and maintenance work.
  • the invention is based on the idea to make one of the two link members of the link coupling partable by constructing the same from two parts releasably connected to each other, namely a first part, which may be permanently connected to the hinge, and a second part, which is fastenable on one of the chassis, wherein the second link member can be allowed to be permanently fastened on the other chassis. Separation of the chassis may then be carried out by removing dismountable connecting elements, e.g., screws, which normally hold together the two parts of the partable link member.
  • one part of the partable link member may be of a male-like character and insertable in a female-like seating in the second part.
  • the two chassis of the car may be brought together without major demand on precision in connection with reconnection.
  • the invention in connection with such cars that include two independently wheel-carried chassis or car bodies, i.e., chassis that individually are carried by two pairs of wheel or wheel bogies, the same is particularly suitable for use in cars of the type that includes a so-called Jakobs bogie, i.e., a bogie that simultaneously carries ends of chassis facing each other, which chassis have own wheels or wheel bogies only at the opposite ends thereof.
  • numerals 1, 2 designate parts of two chassis or car bodies, which together form a rail-mounted car for railway traffic.
  • the two chassis are carried by a common Jakobs bogie generally designated 3, while the same chassis at the non-visible ends thereof are carried by own wheels or wheel bogies.
  • the schematically shown Jakobs bogie 3 includes a framework 4 and at least two pairs of wheels 5 and shock absorption means in the form of four elastic cushions 6 arranged in pairs and applied under assembling plates 7, which can be fixed underneath the individual chassis.
  • the joint between the assembling plates 7 and the individual car chassis is outlined by means of male elements or pins 8 on the top sides of the plates and downward open seatings or holes 9 on the bottom sides of the chassis.
  • This link coupling is generally designated 10 and includes two link members, which are interconnected via a hinge in its entirety designated 11, which in the previously described way includes a vertical pin 12, which enables turning of the link members in relation to each other in the horizontal direction, as well as a partly spherical bearing box 13 (so-called elastomer bearing), which enables rotary motions and oscillatory motions in the vertical direction between the link members.
  • the vertical, geometrical axis of the pivot pin 12 is designated C.
  • a first link member 14, which is connected to the chassis 2, is situated to the right of the hinge 11 in fig.
  • link members 14, 15 are permanently fixed at the respective chassis in so far that they after initial mounting on the chassis should not need to be removed even in connection with repairs and maintenance.
  • the link members are not welded to the chassis, but rather connected to the same via releasable connecting elements, which enable exchange of the link members, e.g., after emergence of serious damage on the same or the chassis.
  • one of the two link members 14, 15, namely. the first link member 14, is partable by being composed of two parts releasably connected to each other, namely a first part 16, which is permanently connected to the second link member 15 via the hinge 11 (see figs. 2 and 5 ), and a second part 17 (see figs. 3 and 6 ), which is permanently connected to the chassis 2.
  • the part 16 is denominated "bearing bracket", while the part 17 popularly is denominated "shelf". More concrete, the first link part 16 is of a male-like character and insertable in a female-like seating in the second link part 17.
  • the link part 17 is composed of a bottom plate 18, an upright transverse end plate 19, and two vertical side pieces or side plates 20, which are stiffly united to the end plate 19 as well as the bottom plate 18, preferably by being welded against the same.
  • an upward as well as forward open seating or space is defined in which the bearing bracket 16 can be received.
  • two fastening plates 21 extend to which two longitudinal, vertical guide plates 22 are stiffly united. Said last-mentioned plates may be inserted between two blocks 23 protruding downward from the bottom side of the chassis and being of a type that is standard on car chassis of the kind in question.
  • the blocks 23 are located in the area between the two support surfaces 24, which rest against the assembling plates 7 of the Jakobs bogie. Together, the plates 18-22 (see fig. 3 ) form a shelf-like frame that is form-stiff and capable of sustaining weight.
  • holes 25 are recessed for dismountable fastening or locking elements 26, e.g., screws, by means of which the fastening plates may be fixed against the bottom sides of the blocks 23.
  • holes 27 are formed in the end wall 19 for horizontal screws or fastening elements 28, which may be tightened in holes in the front surfaces of the blocks 23.
  • the first centring device 33 is in the form of a protruding male element having a rotationally symmetrical basic shape, while the device 34 consists of a downwardly opening, analogously shaped seating in which the male element 33 engages.
  • the seating 33 is formed in the bottom side of the bottom plate 18 the link part 17, the pivot pin 12 not having contact with the centring devices.
  • the link part 16 is stiffly united to the link part 17 (by means of the screws 31), the construction being so formed that the pivot pin 12 and the male element 33 automatically are centred in relation to the geometrical centre axis C when the link part 16 assumes correct position in relation to the link part 17.
  • the second link member 15 includes a front link head 35 and a rear carrier generally fixedly connectable to an appurtenant chassis and designated 36.
  • said carrier includes one or two bottom plates 37 and a vertical plate 38 in the form of a front plate from which two vertical side pieces 39 extend, which are stiffly united to the front plate as well as the bottom plate.
  • the side pieces are oriented perpendicularly to the front plate and mutually spaced-apart, at the same time as they separately are located at a certain distance inside the opposite side edges of the bottom plate 37.
  • the frame 36 (as well as the frame 17) is made from a strong steel plate, e.g., having a thickness within the range of 25-50 mm.
  • a back piece 40 included in the carrier is even stronger, which piece advantageously can be made in the form of a solid cast iron body, which is connected to the side pieces 39 of the frame 36 via one or more strong connecting elements 41, e.g., thick bolts or pins.
  • the frame 36 may be connected to the appurtenant chassis by means of bolts that are tightened in the block 23 of the chassis via holes 25, 27.
  • an axially oriented guide bar 48 is arranged, which engages a co-operating groove 43 in the cross piece 42 of the link head. Upon translational move of the link head in relation to the frame, accordingly the link head is guided by the bars 48.
  • a collision protection is integrated in the link member 15, which in the example is in the form of three tubes or sleeves 49, 50, namely a central tube 49 of a first type, and two co-lateral tubes 50 of another type. All tubes are deformable and co-operate with through bores 51, 52 formed in the back piece 40, which bores have a smaller diameter than the appurtenant tube.
  • the intermediate deformation tube 49 together with the appurtenant bore 51 has a larger diameter than the two co-lateral tubes 50 and the bores 52 thereof.
  • the bores 50, 51 have different diameters, the same are formed in principally the same way. See in this respect fig.
  • FIG. 10 which shows a thin deformation tube 50 together with the appurtenant bore 52.
  • a funnel-like, conical mouth 53 is formed, which widens in the forward direction.
  • the deformation tube 50 is of a cylindrical basic shape, but has at the rear end thereof a conical tapering portion 54, which is inserted into the conical mouth 53. In this position, the tube is kept in place by means of a holder in its entirety designated 55.
  • the mouth 53 and the conical portion 54 of the tube has one and the same conicity or cone angle. Said cone angle should amount to at least 5° and at most 20°, and suitably be within the range of 10-16°. Tests that form the basis of the invention have been most successful when the cone angles have varied within the range of 11-15°.
  • the deformation tube 50 is distanced from the cross piece 42 of the link head via a gap 57.
  • the tube end 56 may advantageously consist of a planar, ring-shaped surface, which extends perpendicularly to the geometrical longitudinal axis of the tube.
  • the axial extension of the gap 57 may be within the range of 10-20 mm.
  • the corresponding gap of the intermediate deformation tube 49 may have another, for instance smaller, axial extension than the gap 57 of each thin deformation tube 50.
  • the corresponding gap length of the tube 49 may be within the range of 5-15 mm.
  • the cross piece 42 impinges on the deformation tubes 49, 50, which will be pressed into the appurtenant bore 51, 52 in the back piece up to a point where the cross piece is stopped against the back piece.
  • the individual tube is pressed into the appurtenant bore, the same will be deformed successively by being compressed or pressed together in the radial direction, while the outer diameter of the tube is reduced to the same inner diameter as the smallest diameter of the cone mouth 53.
  • the kinetic energy in the detached link head is converted into heat in the deformation tubes as well as the back piece. This means that a substantial part of the kinetic energy is extincted before it has time to be transferred from one of the car chassis to the other.
  • the link part 17 is mounted on one of the chassis 2 and the link member 15, with the ensuing link part 16, on the other chassis 1. Fixation of the shelf and box-like frames 36, 17, respectively, is carried out in the above described way by means of screws or bolts 26, 28, which are tightened in threaded holes in the blocks 23 of the chassis.
  • the end of the chassis 2 not equipped with wheels is lifted in above the Jakobs bogie 3 and is located in a position in which the male elements 8 can be brought to engagement with the seatings 9 at the same time as the centring devices 33, 34 engage each other.
  • a fundamental advantage of the invention is that two chassis included in a car can be connected and disconnected without any need for manipulating the hinge between the link members of the link coupling. Neither the more or less theoretical possibility of removing a link member from the appurtenant chassis needs to be resorted to.
  • the invention is not limited only to the embodiment described above and shown in the drawings.
  • the invention is applicable also to such link devices or link couplings that lack collision protection. It is also feasible to apply the invention to such link couplings that do not co-operate with any Jakobs bogie.
  • the link coupling can also be used for such cars the chassis of which are separately wheel-carried at the two ends thereof.
