Definitions

  • the invention relates to a rail vehicle with a bogie linkage for a bogie with a trailing arm, wherein the trailing arm pivotally connects a car body and a bogie frame, wherein the bogie frame comprises two side members and wherein the trailing arm has a bearing at both ends.
  • connection of bogie and car body using a trailing arm is required in many rail vehicles, for example, to transfer traction and braking forces from the bogie to the car body.
  • Jakobs bogie is from the DE 196 38 763 C2 known.
  • the DE 196 38 763 C2 is considered in the context of the invention as the closest prior art, although the invention is not limited to the coupling of Jakobs bogies with a car body.
  • the axes of rotation of the bearings of the trailing arm can run in the vertical direction;
  • the space requirement in the vertical direction is relatively high despite this arrangement, because the bearing pin is held in a fork-shaped receptacle.
  • the claimed invention can also be used successfully in other types of bogies.
  • the invention has for its object a rail vehicle with, to provide a bogie connection, the space requirement is reduced, especially in the vertical direction.
  • This advantage is further increased when the head of the central screw is sunk in the journal of the bearing.
  • Another advantage of the arrangement according to the invention is given by the fact that the space requirement of a trailing arm for larger loads in the vertical direction does not increase or only to a very small extent.
  • a more resilient trailing arm requires more space in the first place in the horizontal direction and perpendicular to its longitudinal axis, since the bearings must have a larger diameter and of course the cross section of the trailing arm in the middle region between the two camps increases.
  • This means that the space requirement of the invention arranged trailing arm in the vertical direction is almost independent of its rigidity and strength.
  • the available space in the bogie can be further increased by the trailing arm at least partially protrudes vertically downwards over one or both side members of the bogie frame.
  • the bogie has at least two cross members, which are arranged between the longitudinal members, it has also proved to be advantageous if at least one bearing of the trailing arm between two cross members is arranged.
  • the trailing arm extends at least partially in the vertical direction down over one or both cross member.
  • the bearings of the invention trailing arms are designed so that they allow a rotational movement of the trailing arm in a plane passing through the vertical axis of rotation of the bearing and a - Is moved substantially horizontally extending - longitudinal axis of the trailing arm.
  • the inventive arrangement of the trailing arm has proven in connection with Jakobs bogies.
  • Jakobs bogies the ends of two car bodies rest on separate bogies on separate bogies and are hinged together via an articulated coupling.
  • the trailing arm according to the invention now serves to train and To transmit compressive forces between the bogie and one of the two lying on the bogie car bodies.
  • the secondary springs are relieved of the compressive and tensile forces, which are caused in particular by the drive motors in the bogies and the brakes of the bogies.
  • FIG. 1 shows a plan view of a Jakobs bogie 1.
  • the bogie 1 has an H-shaped frame, which consists of two longitudinal members 3 and two cross members 5. About the cross member 5, the side members 3 are firmly connected. At the ends of the longitudinal members 3 each have a wheel set 7 is present. The wheelsets 7 are a primary suspension (not visible in FIG. 1 ) connected to the bogie frame.
  • the drive motors of the wheelsets 7 are for reasons of clarity in FIG. 1 not shown.
  • a total of four secondary springs 9 are arranged on the side rails 3 .
  • the secondary spring 9 one or two car bodies (not shown in FIG. 1 ). Since it is a so-called Jakobs bogie in the present embodiment, one end of a first carbody, not shown, is placed on the secondary springs 9.1, while a second likewise not shown car body is placed on the secondary springs 9.2.
  • the car bodies are connected to each other via an articulated coupling, so that the car bodies can move relative to each other when cornering.
  • height differences in vertical Direction that result, for example, by different loadings of the car bodies or dynamic loads are compensated.
  • a trailing arm 13 is disposed on a cross member 5.1 of the bogie 1.
  • the trailing arm 13 is rotatably supported by means of a first bearing 15 on the cross member 5.1.
  • the main degree of freedom of the first bearing 15 is in FIG. 1 arranged by the double arrow 17.
  • the first bearing 15 remote from the end of the arm 13 is also rotatably mounted in a second bearing 19.
  • the second bearing 19 is arranged on a bracket 21 of the carbody, not shown.
  • the main degree of freedom of the second bearing 19 is indicated by a double arrow 23.
  • the trailing arm 13 allows the transmission of tensile and compressive forces between the car body, not shown, which rests on the secondary springs 9.2, and the bogie 1. At the same time allow the bearings 15 and 19, a rotational movement of the car body relative to the bogie.
  • the axes of rotation (without reference numeral) of the bearings 15 and 19 Run substantially in the vertical direction and thus in FIG. 1 perpendicular to the plane of the drawing.
  • the load capacity of the trailing arm 13 is decisively determined by a width B and a diameter (without reference numeral) of the bearings 15 and 19. This means that with an increase in the bearing dimensions or a reinforcement of the trailing arm 13, the space requirement increases especially in the lateral direction, that is in the plane of the drawing.
  • FIG. 2 a section along the line AA is shown.
  • the same components have the same reference numerals and it applies the respect FIG. 1 Said accordingly.
  • FIG. 2 is greatly simplified a car body 25, which rests on the secondary springs 9.2, indicated. About a connecting element 27, which is also shown only schematically, the console 21 is rigidly connected to the car body 25.
  • the axes of rotation of the bearings 15 and 19 are indicated by dashed lines 29. From the FIG. 2 It is clear that the axes of rotation extend substantially in the vertical direction and for this reason the space requirement of the trailing arm 13 according to the invention in the vertical direction is relatively low.
  • FIG. 2 the secondary spring 9.2 is shown with the car body 25 empty.
  • the secondary spring 9.2 springs in either by unevenness of the route or a loading of the car body 25, the car body 25 moves in the direction of the bogie 1, because the secondary spring 9.2 springs.
  • the console 21 with the second bearing 19 drops slightly.
  • the trailing arm 13 according to the invention is attached to the first bearing 15 and the second bearing 19 so that it is substantially horizontal when fully spring-loaded secondary spring 9.2.
  • a longitudinal axis of the trailing arm 13 is in FIG. 2 provided with the reference numeral 30. The above is still in connection with the FIGS. 4a) and 4b ) explained in more detail.
  • FIG. 2 It can be seen that the trailing arm 13 arranged according to the invention, in particular in the region of the first bearing 15, protrudes downward in a vertical direction over both the cross member 5.1 and the longitudinal members 3. As a result, space between the longitudinal members 3 on the one hand and the cross members 5.1 and 5.2 on the other hand won.
  • FIG. 3 is a section of the bogie 1 with the cross member 5 and shown with the invention arranged trailing arm 13 in an isometric view. In this isometry, the inventive arrangement of the trailing arm 13 is clearly visible.
  • FIG. 4 the cross members 5.1 and 5.2, the trailing arm 13 and the bracket 21 are shown in section. Among other things, the connection of the first bearing 15 to the cross member 5.1 is clearly visible from these figures.
  • FIG. 4a is the secondary spring 9.2 (see FIG. 2 ) shown in an empty car body 25.
  • a lower edge of the second bearing 19 is arranged by the dimension D higher than a lower edge of the first bearing 15.
  • the dimension D corresponds to a first approximation of the deflection of the secondary spring 9.2.
  • a mounting hole 31 is provided in the cross member 5.1.
  • a bearing cap 33 is inserted from above.
  • the bearing cap 33 has a centrally arranged internal thread 35.
  • a bearing pin 37 is inserted from below and connected by means of a central screw 39 to the bearing cap 33. It is about a cone 41 a non-positive connection between pin 37 and bearing cap 33 made.
  • the pin 37 is crowned in the region of the trailing arm. This convex portion (without reference numeral) of the pin 37 is surrounded by a correspondingly shaped rubber element 43.
  • the rubber element 43 is connected either directly to the trailing arm 13 or via a metal sleeve 45 with the trailing arm 13. The rubber element 43 is vulcanized directly onto the pin 37.
  • the head of the central screw 39 is recessed in the pin 37, so that the space requirement of the first bearing 15 in the vertical direction is further reduced.
  • the bearing 15 allows both rotations about the vertically arranged axis of rotation 29 (main degree of freedom) and deflections of the trailing arm 13 in a plane which is spanned by the axis of rotation of the first bearing 15 and the longitudinal axis 30 of the trailing arm 13. As a result, relative movements of bogie and car body in the vertical direction can be compensated by the bearing 15.
  • the inventive arrangement of the trailing arm 13 is a very space-saving arrangement in the vertical direction, which directly in a gain in available space in the bogie and / or a lowering of the car floor of the car body 25 allows. Both Of course, advantages can also be combined with one another as required.
  • FIGS. 6 and 7 show in a second embodiment of the invention, the bogie linkage with trailing arm, installed in a conventional bogie in plan view and longitudinal view.
  • the same reference numerals are used and the same applies with regard to the first exemplary embodiment.
