Definitions

  • the invention relates to an energy dissipating device suitable to be used as part of a connection device that connects a first car of a multi-car vehicle with a second car of the multi-car vehicle.
  • the invention also relates to a connection device suitable to connect a first car of a multi-car vehicle with a second car of the multi-car vehicle.
  • the invention also relates to a method for building such a connection device.
  • Multi-car vehicles are known in different designs and in different forms of adaptation for uses.
  • Multi-car vehicles for example, railway-bound trains (street cars and subway-trains also being considered as such trains) are known and are known for the purpose of transporting passengers as well as transporting goods.
  • Further types of multi-car vehicles can be magnetic railway trains or can be buses (road buses as well as buses travelling on fixed tracks).
  • a car of a multi-car vehicle can be a self-supporting cars, whereby the car has sufficient wheels that are placed at sufficient locations such that the car can stand by itself without being supported by other cars, for example a three-wheeled car, a four wheeled car or a car with even more wheels placed suitable locations.
  • a car of a multi-car vehicle can also be of the non-self-supporting type, whereby the car has no wheels or only wheels provided in such number or arranged at such a place that the car cannot stand by itself, but is vertically supported by at least one neighbouring car.
  • the individual cars of the vehicle are connected to one another by means of a connecting device.
  • the connecting devices can be provided for different types of purposes. In multi-car vehicles where only one or only several of the total of cars is driven, the connecting devices are provided so that a driven car can drive a non-driven car and thus ensure that the complete vehicle travels with the same speed.
  • Connecting devices are also distinguished between those connecting devices that allow for an easy decoupling of the cars, whereby easy decoupling is understood to be accomplished within a couple of minutes, or for what is called “semi-permanent" coupling of the cars, for which decoupling of the cars takes efforts and usually involves the vehicle to have been transported to a specific work shop. Trains, for example, can have coupler-heads as part of their connecting devices. These coupler-heads can, for example, be so called “automatic couplers" that allow decoupling within minutes.
  • connection devices that are suitable to connect a first car of a multi-car vehicle with a second car of a multi-car vehicle with energy dissipating devices.
  • an energy dissipating device suitable to be used as part of a connection device that connects a first car of a multi-car vehicle with a second car of the multi-car vehicle is known.
  • the connection device in this embodiment is designed as an articulated joint.
  • the energy dissipating device arranged as part of the connection device has an energy dissipating member in the form of a deformation tube that dissipates energy when it is deformed.
  • the deformation tube has a first end and a second end, the first end and the second end being spaced apart from each other in a compression stroke direction, which is in line with the longitudinal axis of the articulated joint when it is in the straightened-out mode of operation.
  • the energy dissipating device has a stopper in the form of a pressure plate.
  • the pressure plate has a stopping surface and the first end of the energy deformation tube is in contact with the stopping surface, the stopping surface preventing that the first end moves in the compression stroke direction, because the pressure plate is screwed to flange parts surrounding the deformation tube.
  • the energy dissipating device furthermore has a deformer, which is called guiding profile (Fckenungsprofil) in EP 1 312 527 A1 .
  • a mandrel is provided that is in contact with the second end of the deformation tube and that is held apart from the pressure plate by the deformation tube, whereby the guiding profile can be moved towards the pressure plate by application of a linear force pointing in the compression stroke direction that is larger than a predetermined threshold value and thereby the guiding profile deforms the deformation tube when moving towards the pressure plate.
  • the mandrel moves into the deformation tube and deforms it outwardly.
  • the guiding profile is guided on straight-line rails provided at either end of the deformation tube in the flange parts that surround the deformation tube and to which the pressure plate is fastened by screws.
  • an energy dissipating device of a connection device that connects a first car of a multi-car vehicle with a second car of the multi-car vehicle is known.
  • the energy dissipating device has an energy dissipating member in the form of a deformation tube that dissipates energy when it is deformed.
  • the deformation tube has a flange arranged at a first end of the deformation tube, which is intended to rest against a panel of the first car.
  • a deformer Arranged inside the deformation tube at the first end of the deformation tube is a deformer that has a mandrel arranged at its end that rests against a waist of the deformation tube whereby the diameter of the deformation tube is reduced at this waist.
  • An energy dissipating device suitable to be used as part of a connection device that connects a first car of a multi-car vehicle with a second car of the multi-car vehicle is also known from EP 2 949 539 A1 .
  • the deformation tubes used as energy dissipating members in EP 1 312 527 A1 , WO 2005/075272 A1 and EP 2 949 539 A1 are deformed fully with regard to their cross section.
  • the respective mandrel deforms the complete cross section of the respective deformation tube such that in the cases of WO 2005/075272 A1 and EP 1 312 527 A1 , where the mandrel is placed inside the deformation tube, the outer diameter of the deformation tube after deformation is larger than the outer diameter of the deformation tube before deformation, while at the same time the inner diameter of the deformation tube after deformation is larger than the inner diameter before the deformation.
  • gas hydraulic dampers In many embodiments, gas hydraulic dampers are implemented in the coupler rod of a connection device. These gas hydraulic dampers take up some of the small forces that occur during normal travel of the vehicle and smoothen the ride. Gas hydraulic dampers often have a piston that moves inside a tubular member. These parts can be used to implement the energy dissipating device according to the invention, for example by using the piston as plug according to the invention and implement the mandrel on the tubular member that surrounds the piston. The advantages of the invention can be taken so far as to implement the energy dissipation solely on elements already present in a coupling device without the need to implement an additional energy dissipating device like a deformation tube in the connection device. This will save built-length of the complete connection device and will save weight.
  • the problem to be solved by the invention is to provide an energy dissipating device suitable to be used as part of a connection device that connects a first car of a multi-car vehicle with a second car of the multi-car vehicle that can be built in a more lightweight manner. It is also an object of the invention to suggest a connection device having such an energy dissipating device and a method for building such a connection device.
  • the general concept of the invention is to provide a rib (preferably a plurality of protruding ribs) on at least one of two objects that are moved relative to each other, if a force is applied to one of the two objects, and to have the protruding rib being at least partially deformed when the one object is moved relative to the other object.
  • a rib preferably a plurality of protruding ribs
  • the effect of smearing the material of the object to be deformed is used.
  • Providing protruding ribs leaves space next to the ribs, into which the material can be smeared. To achieve the energy dissipating effect, it is therefore also not necessary, to cut into material, i.e. to sever material from the object.
  • the energy dissipating device has a plug that has a longitudinal axis as will be described further below.
  • the plug can be a tubular object, preferably a deformation tube. Since the invention is based, however, on the cooperation of two objects and only necessitates one of the two objects to be an energy dissipating object, the plug also can be a rigid object, if it is made to cooperate with a second object, namely the mandrel, if the mandrel is designed to be energy dissipating.
  • the plug is described to have a longitudinal axis in order to allow a relative movement between the plug and the mandrel to be described.
  • the term "longitudinal axis" does, however, not mean that the maximum extent of the plug is in direction of the longitudinal axis. Embodiments of the invention can be thought of, where the plug has a larger extent in a direction perpendicular to the longitudinal axis than in the direction of the longitudinal axis. However, in a preferred embodiment, the maximum extent of the plug is in the direction of the longitudinal axis.
  • the plug is an object with rotational symmetry with respect to the longitudinal axis. That is in a preferred embodiment there is at least one sectional plane perpendicular to the longitudinal axis in which plane the section of the plug is an object with rotational symmetry about the longitudinal axis.
  • the respective section of the plug in that respective sectional plane is an object with rotational symmetry about the longitudinal axis.
  • the longitudinal axis of the plug points in the direction of or parallel to the direction of the maximum extend of the plug.
  • the longitudinal axis is co-axial or parallel to the central axis of the hole in the mandrel.
  • the energy dissipating device has a mandrel that has an opening, whereby the plug is arranged to be moved at least partially through the opening if a force pointing in the direction of or parallel to the direction of the longitudinal axis is applied to the plug and whereby at least a part of the plug and/or at least a part of the mandrel is deformed, when the plug is at least partially moved through the opening.
  • the plug is already partially, even if it is minimally, inserted into the opening of the mandrel in the normal mode of operation of the energy dissipating device, i.e. the mode of operation where the energy dissipation has not taken place yet.
  • Arranging the plug to be partially inserted into the opening of the mandrel allows for the relative movement of the plug relative to the mandrel to be coordinated in a better manner.
  • designs can be thought of, where the plug is held distanced from the opening and whereby the plug first needs to be moved to engage into the opening of the mandrel, if a force pointing in the longitudinal axis is applied to the plug, before deformation can begin.
  • the invention can be achieved by two alternatives, which can also be combined.
  • the outer surface of the plug has at least one protruding rib that extends in the direction of or parallel to the direction of the longitudinal direction, said rib being at least partially deformed, when the plug is at least partially moved through the opening.
  • the surface of the mandrel that surrounds the opening has at least one protruding rib that extends in the direction of or parallel to the direction of the longitudinal direction, said rib being at least partially deformed when the plug is at least partially moved through the opening.
  • the maximum diameter of the plug in a plane perpendicular to the longitudinal axis is larger than the minimum diameter of the opening of the mandrel.
  • the outer surface of the plug is described to have at least one protruding rib and given that the outer surface of the plug therefore need not be an object with constant diameter in a plane perpendicular to the longitudinal axis
  • the term "maximum diameter" is understood to be the length of that line of all lines that in a plane perpendicular to the longitudinal axis connects one point on the outer surface of the plug with a second point on the outer surface of the plug, while crossing the longitudinal axis which has the maximum length.
  • the term "minimum diameter" is understood to be the length of that line of all lines that in a plane perpendicular to the longitudinal axis connects one point on the surface of the mandrel that surrounds the opening with a second point on the surface of the mandrel that surrounds the opening, while crossing the longitudinal axis, which has the minimum length.
  • the rib is claimed to extend in the direction of or parallel to the direction of the longitudinal axis. This leads to the effect that as the plug is moved into the opening in the direction of its longitudinal axis, further parts of the rib are made to engage with parts of the mandrel and are thus being deformed. This enhances the total amount of energy being dissipated as the plug is moved into the opening of the mandrel.
  • the term "one protruding rib that extends along the longitudinal axis” also includes “one protruding rib that extends along a direction parallel to the longitudinal axis”. This depends on what is considered to be the longitudinal axis of the plug.
  • the one protruding rib arranged at the outer surface of the plug extends along a direction parallel to the longitudinal axis of a such defined longitudinal axis of the plug.
  • the term "one protruding rib that extends along the longitudinal axis” also includes the term “one protruding rib that extends in a direction, which direction can be fragmented into two vectors that are perpendicular to one another, whereby one of the two vectors points in the direction of the longitudinal axis or in a direction parallel to the direction of the longitudinal axis".
  • At least one protruding rib in a plane perpendicular to the longitudinal axis of the plug has a square cross section or a triangular cross section or a trapezoid cross section or the cross section of a segment of a circle.
  • the geometric shape of the cross section of the protruding rib stays the same along its extent along the longitudinal axis.
  • the surface area that the section of the protruding rib in a section perpendicular to the longitudinal axis takes up, stays the same along the extent of the protruding rib along the longitudinal axis.
  • Embodiments can, however, be thought of, where the surface area that a section of a protruding rib takes up in a plane perpendicular to the longitudinal axis decreases when compared to the surface area that a section of a protruding rib takes up in a plane perpendicular to the longitudinal axis when take at a different position along the longitudinal axis of the plug. This can either be achieved by reducing the height of the rib over the basic body of the plug or the height that the rib extends into the opening of the mandrel, if the rib is arranged at the mandrel.
  • This increased merger of the rib with the basic body of the plug makes it more difficult to deform the plug the more the plug enters into the opening and hence increases the energy necessary to perform this deformation.
  • Such a design can be used to stop the amount of travel of the plug into the opening of the mandrel.
  • the protruding rib terminates at its radially most outward end in an end surface that has a circumferential extent and an extent in a direction perpendicular to the longitudinal axis of the plug.
  • this end surface has the shape of a section of an outer surface of a cylinder.
  • the outer surface of the plug has a plurality of protruding ribs that extend in the direction of or parallel to the direction of the longitudinal axis, said ribs being at least partially deformed, when the plug is at least partially moved through the opening, and/or the surface of the mandrel that surrounds the opening has a plurality of protruding ribs that extends in the direction of or parallel to the direction of the longitudinal axis, said ribs being at least partially deformed, when the plug is at least partially moved through the opening.
  • Providing a plurality of protruding ribs increases the material that is deformed during energy dissipation and hence allows the amount of energy dissipated during energy dissipation to be increased.
  • the protruding ribs are equally spaced over the outer surface of the plug.
  • the plug has a tubular shape, especially preferred the shape of a hollow cylinder, whereby the plurality of protruding ribs is arranged on the outer surface of this tubular body.
  • all of the plurality of protruding ribs extend in the same direction and keep the same distance to their neighbouring ribs as they extend along the longitudinal direction.
  • the plug has a basic body with the protruding ribs arranged on the outer surface of this basis body, whereby the basic body - if the protruding ribs are imagined not to be there - has a specific geometric shape of its outer circumference, whereby in the preferred embodiment, the shape of the opening of the mandrel has the same shape.
  • the opening has a circular or elliptical cross section, whereby in the embodiments of the second alternative, where the mandrel has at least one protruding rib, this one protruding rib of the mandrel protrudes inwards into such a circular or elliptical opening.
  • the envelope that connects the most protruding point of each rib in a plane perpendicular to the longitudinal axis has a circular or elliptical shape.
  • the maximum diameter of the envelope is larger than the minimum diameter of the opening at the mandrel.
  • valleys are provided between the protruding ribs.
  • the outer surface of the plug has the plurality of protruding ribs that extend in the direction of or parallel to the direction of along the longitudinal axis and in that the mandrel has an inclined surface facing the ribs wherein said inclined surface inclines towards the longitudinal axis and/or the ribs each have an inclined front surface facing the mandrel wherein said inclined front inclines away from the longitudinal axis. Providing for such inclined fronts or such an inclined surface enhances the way that the ribs are deformed as the plug is moved further into the opening of the mandrel.
  • the surface of the mandrel that surrounds the opening has the plurality of protruding ribs that extends in the direction of or parallel to the direction of the longitudinal axis and in that the plug has an inclined surface facing the ribs wherein said inclined surface inclines away from the longitudinal axis and/or the ribs each have an inclined front surface facing the plug said inclined front inclines towards the longitudinal axis.
  • the outside angle between the inclined surface on the mandrel and the longitudinal axis of the plug is less than 90°, preferably less than 80°, even more preferred less than 70°, and even more preferred less than 60°, and even more preferred less than 50°, and even more preferred less than 45°, and even more preferred less than 40°.
  • the inside angle between the inclined front and the longitudinal axis of the plug is less than 90°, preferably less than 80°, even more preferred less than 70°, and even more preferred less than 60°, and even more preferred less than 50°, and even more preferred less than 45°, and even more preferred less than 40°.
  • the plug is a deformation tube. Designs can be thought of, where a first energy dissipation takes place as ribs are deformed as the plug is moved further into the opening of a mandrel and where a further opening is provided behind the opening of the mandrel, which forces the deformation tube to be further deformed, namely in a manner similar to the deformation of the deformation tubes in the prior art. This leads to a staggered dissipation of energy.
  • the plug is made of a medium/high strength steel with good elongation properties.
  • the mandrel is made of a ultra-high strength steel with high yield stress and hardness.
  • connection device suitable to connect a first car of a multi-car vehicle with a second car of the multi-car vehicle according to the invention comprises an energy dissipating device according to any one of claims 1 to 7.
  • the method for building a connection device provides for the plug to be arranged in front of the mandrel so as to allow the plug to be moved at least partially through the opening, if a force pointing in the longitudinal axis is applied to the plug.
  • the Fig. 1 to 6 only show one quarter 1, 101 of a plug and one quarter 2, 102 of a mandrel of embodiments of the invention.
  • the plug and the mandrel each are completed by further three quarters (not shown in the Fig 1 to 6 ) that look identical to the quarters shown and are arranged around the longitudinal axis A of the plug to complete the plug and the mandrel.
  • the plug and the mandrel are part of an energy dissipating device suitable to be used as part of a connection device that connects a first car of a multi-car vehicle with a second car of the multi-car vehicle.
  • the Devices comprises the plug that has a longitudinal axis A and the mandrel that has an opening 3, 103.
  • the plug is arranged to be moved at least partially through the opening 3, 103, if a force pointing in the direction of or parallel to the direction of the longitudinal axis A is applied to the plug.
  • the outer surface of the plug has a plurality of protruding ribs 4 that extend in the direction of or parallel to the direction of the longitudinal axis A.
  • the mandrel has an inclined surface 5 facing the ribs 4 wherein said inclined surface 5 inclines towards the longitudinal axis A.
  • the outside angle between the inclined surface 5 on the mandrel and the longitudinal axis A is less than 90° and about 25-30°.
  • the maximum diameter of the plug in a plane perpendicular to the longitudinal axis is larger than the minimum diameter of the opening of the mandrel. Therefore the ribs 4 will be partially deformed, when the plug is at least partially moved through the opening 3. Because valleys 6 are arranged between the ribs 4, the deformation of the ribs 4 will lead to material from the ribs 4 to be smeared into these valleys 6.
  • the embodiment shown in Fig. 4 to 6 differs from the one shown in Fig. 1 to 3 in that the ribs 104 are arranged to surround the opening 105 of the mandrel.
  • the surface of the mandrel that surrounds the opening has a plurality of protruding ribs 104 that extend parallel to the direction of the longitudinal axis A, said ribs 104 being at least partially deformed, when the plug is at least partially moved through the opening as can best be seen when comparing Fig. 5 (deformed ribs 104) to Fig. 6 (ribs 104 just before deformation).
  • Fig. 5 deformed ribs 104
  • Fig. 6 ribs 104 just before deformation
  • the plug has an inclined surface 107 facing the ribs 104 wherein said inclined surface inclines away from the longitudinal axis A and the ribs 104 each have an inclined front surface108 facing the plug said inclined front 108 inclines towards the longitudinal axis A.
  • Valleys 106 are provided between the ribs 104.
  • Fig. 7 shows schematic front view onto a protruding rib 204 arranged to surround the opening 205 of the mandrel just before it comes into contact with the inclined surface 207 of the plug.
  • Fig. 8 shows the view of Fig. 7 , but how the rib 204 smears away the material of the plug. A bulk 210 of material is made during this smearing, which enters into the gap between adjacent ribs 204.
  • Fig. 9 shows a schematic front view onto rib 304 protruding from a plug just before it comes into contact with the inclined surface 305 of the mandrel.
