  • the pivotable movement of the stopper relative to the end section (if the stopper is designed pivotably connected to the end section) must have a limit which does not allow the stopper to pivot further relative to the end section than this limit in order to allow for the transmittal of forces to create the rectifying momentum and to avoid the stopper from pivoting away from this limit at the time of creating the rectifying momentum.

  • This normal driving condition can be understood as the first driving condition.
  • the connection device is preferably used in the context of creating a rectifying momentum in driving condition where the end section has pivoted out of the normal driving condition with the aim to move the end section back into the normal driving position
  • the first driving condition is preferably understood to be a driving condition, where the end section has pivoted away from the normal driving condition about the pivot axis. Due to the elastic element the surface section of the stopper element and the surface section of the bearing bracket are preferably kept distanced from each other in driving conditions where only forces below a predetermined magnitude are applied along the longitudinal axis of the end section of the coupler rod or connection rod.
  • the elastic element will be deformed by such an extent that the surface section of the stopper comes into contact with a surface section of the bearing bracket. This contact will take place at a distance relative to the point of pivotable connection to the bearing bracket (for example the hole in the bearing bracket through which the end section passes) and thus at a distance from the point at which the longitudinal axis of the end section of the coupler rod or connection rod intersects the bearing bracket.
  • the same force that is applied from the surface section of the stopper element onto the surface section of the bearing bracket due to the force along the longitudinal axis being applied is applied from the surface section of the bearing bracket onto the surface section of the stopper.

  • a rectifying momentum tends to move the end section back into the normal driving condition.
  • the level of force that needs to be applied to bring the surface section of the stopper into contact with the surface section of the bearing bracket depends on the elasticity of the elastic element.
  • the bearing bracket and/or the stopper has a recess such that in a second driving condition that is different from the first driving condition in that the end section has a second position relative to the bearing bracket, the surface section of the stopper passes the surface section of the bearing bracket.
  • the surface section of the stopper and/or the surface section of the bearing bracket that come into contact in the first driving condition are of such limited extent that the second driving condition, which is preferably a driving condition where the end section has pivoted relative to the bearing bracket about an even larger angle, cannot come into contact with each other but move past each other.
  • the second driving condition which is preferably a driving condition where the end section has pivoted relative to the bearing bracket about an even larger angle
  • the size and shape of the recess as well as its positioning along the stopper (in the direction perpendicular to the longitudinal axis of the rod) are one factor that influence for which swivel angles a rectifying momentum if provided (contact between the surface section of the stopper and the surface section of the bearing bracket) and for which swivel angles the presence of the recess will prevent a rectifying moment to be created.
  • the stroke of deformation of the elastic element and the elasticity of the elastic element influence how close the stopper comes to the bearing bracket for one given level of force of a force acting along the longitudinal axis of the rod.
  • the stopper and bearing bracket are not to come into contact with each other and do not do so if the rod is in the straight line orientation, but would do so in a swivelled position because of the length of the stopper and the length of the bearing bracket, the recess according to the invention can easily be placed where the stopper would contact the bearing bracket in the swivelled position.
  • the surface section of the bearing bracket that comes into contact with the surface section of the stopper in this embodiment is provided at the bottom of the recess.

  • the force to be applied along the longitudinal axis of the end section of the coupler rod or connection rod necessary to move the surface section of the stopper past the surface section of the bearing bracket is determined by the choice of the elasticity of the elastic element.
  • connection device is designed in such a manner that for a first group of driving conditions, which group is defined by a first set of pivot angles between the longitudinal axis of the end section of the coupler rod or connection rod, the surface section of the stopper comes into contact with the surface section of the bearing bracket, if the application of force along the longitudinal axis of the end section of the connection rod or coupler rod deforms the elastic element.

  • the longitudinal axis of the end section of the coupler rod or connection rod is at 90° to bearing bracket.
  • the above mentioned first set of pivot angles is the set of pivot angles between a minimum pivot angle and a maximum pivot angle.
  • the minimum pivot angle preferably is 0° which means that the first set of pivot angles also includes the normal driving condition. This means nothing else than that the surface sections on the stopper and on the bearing bracket are such arranged and of such extend that also in the normal driving condition the surface section of the stopper and the surface section of the bearing bracket come into contact, if a force is applied along the longitudinal axis of the end section that suitably compresses the elastic element.
  • the maximum angle of the first set of pivot angles is 20°, preferably 15°, even more preferred 10°.
  • the pivot angle between the longitudinal axis and the end section of the coupler rod or connection rod is larger than any of the pivot angles of the first set.
  • connection device according to the invention upon the application of force along the longitudinal axis leads to the surface section of the stopper coming into contact with the surface section of the bearing bracket and thus a rectifying momentum being created, while the connection device according to the invention in this preferred embodiment for larger angles either provides no rectifying momentum at all, because the surface section of the stopper moves past the surface section of the bearing bracket, or creates a rectifying momentum by providing other surfaces of the stopper and the bearing bracket that can interact in that second driving condition (whereby one of the surface sections can the one of those surface sections that interact in the first driving condition and is simply paired to another surface section compared to the surface section used for contact in the first driving condition on its counterpart).

Due to the extent of the surface section 10 and the surface section 11 provided by their straight line cross-section, parts of a surface section 10 come into contact with parts of a surface section 11 even for driving conditions where the end section 3 has pivoted about the pivot axis C-C for predetermined angles, preferably small angles (see Fig. 7, 8 ).
  • a first group of driving conditions which group is defined by a first set of pivot angles between the longitudinal axis B-B of the end section and the bearing bracket 2 that deviate from the 90° condition (normal driving condition shown in Fig.1 ) the surface section 10 of the stopper 5 comes into contact with the surface section 11 of the bearing bracket 2, if the application of force along the longitudinal axis of the end section of the connection rod or coupler rod deforms the elastic element. If the end section 3 pivots counterclockwise in the view shown in Fig. 2 , the surface sections 10 arranged towards the right of the longitudinal axis B-B in Fig. 2 will come into contact with the surface sections 11 arranged on the right of the longitudinal axis B-B (see Fig. 7, 8 ).
  • the stopper 5 has recesses 12.
  • the recesses 12 are arranged such that in a second driving condition (see Fig. 9, 10 ) that is different from the first driving conditions ( Fig. 1 to 8 ) in that the end section 3 has a second position relative to the bearing bracket 2, the surface section 10 of the stopper 5 moves past the surface section 11 of the bearing bracket 2, if a force along the longitudinal axis B-B of the end section 2 and the elastic element is deformed.
  • the pivot angles between the longitudinal axis B-B of the end section and the bearing bracket 2 that deviate from the 90° condition are larger than the pivot angles of the first driving conditions ( Fig. 1 to 8 ). If the end section 3 pivots about the pivot axis B-B about a larger degree such that (when seen in direction of the longitudinal axis B-B) the recess 12 comes into alignment with the surface section 11 of the bearing bracket 2 and if in this driving condition a longitudinal force is applied along the longitudinal axis B-B, the surface section 11 will be taken up by the recess 12 and the surface section 10 of the stopper 5 will pass the surface section 11 (compare Fig. 9 to Fig. 10 ).
  • a neighbouring surface section 13 of the bearing bracket 2 that neighbours the surface section 11 of the bearing bracket 2 in a cross section perpendicular to the pivot axis C-C has a curved contour. This facilitates the movement of the surface section 10 past the surface section 11. The neighbouring surface section 13 will come into contact with one of the walls 14 that delimit the recess 12.
  • the shortest distance C between a line parallel to the longitudinal axis B-B of the end section 3 and offset relative to the longitudinal axis B-B in the direction of the pivot axis C-C and the point 15 of transition from the surface section 11 of the bearing bracket 2 to the neighbouring surface section 13 of the bearing bracket 2 is larger than 110mm, namely 150mm.
  • At least one of the surface sections 10 of the stopper 5 comes into contact with at least one of the surface sections 11 of the bearing bracket 2, if the application of force along the longitudinal axis B-B of the end section 3 deforms the elastic element ( Fig. 4 , 6 , 8 ). If upon contact the force is continued to be applied, a rectifying momentum is generated that is directed to move the end section 3 back towards the normal driving condition.
  • the rectifying momentum can be about the pivot axis C-C, if the end section 3 has only pivoted about the pivot axis C-C.
  • connection device prevents a rectifying momentum to be created by the interaction of the surface section 10 and the surface section 11 in driving conditions with larger pivot angles and thus allows the multi-car vehicle to move around bends with small radius of curvature while at the same time providing for a substantial distance C that will lead to a rectifying momentum of a substantial size being created for the driving conditions with smaller pivot angles.
