Definitions

  • the invention relates to a road vehicle with two vehicle parts, which are connected to each other via a joint, which is provided with damping and / or blocking devices, each comprising a pair of support arms on both sides of the joint, the ends of which when the joint is bent in one direction are clamped against each other with stop surfaces.
  • the invention is therefore based on the object of providing a vehicle of the type mentioned at the beginning, the damping device of which operates smoothly.
  • the solution according to the invention is that the cooperating stop surfaces of the support arms are provided with interlocking elevations and depressions which prevent a lateral relative movement.
  • Coupling elements with elevations and depressions preventing lateral relative movement are known (CH-PS 336 862), but they are intended to prevent a relative movement in the transverse direction between the two coupled rail vehicles. This problem does not occur in the road vehicle according to the invention, since both vehicles are connected by a common swivel joint, so that such a lateral relative movement of the two vehicle parts cannot occur at the connection point.
  • the invention also does not consist of providing special additional parts provided with elevations and depressions, but rather to provide parts already provided with such elevations and depressions.
  • the elevations and depressions are expediently designed as teeth on the convexly formed abutment surfaces.
  • the abovementioned stops are provided, which ensure that the support arms with the stop surfaces located thereon assume a defined position in the released state.
  • stop plates are not kept in constant contact with one another, but detach from one another when the joint is bent in the other direction, it is advantageous to keep the support arms detached from one another ready for engagement by means of stops.
  • the front and rear vehicle parts are arranged. Their chassis extend towards each other extensions 3, 4, which are connected by the hinge 5 to the vertical axis, so that they can be adjusted, for example, as shown in FIG. 2 on a left turn.
  • a pair of support arms 6, 7 are provided on each side of the joint and are tensioned against one another by hydraulic devices 10, 11. Of course, other devices than hydraulic could also be provided in order to generate a force on the support arms 6, 7 which supports the joint against excessive or rapid buckling.
  • the support arms 6, 7 are hinged at 19, 20 to the extensions 3, 4.
  • the articulation points are eccentric to the joint 5.
  • the articulation axes 19 and 20 and the articulation axis 5 are parallel to one another and essentially vertical in the operating position.
  • the support arms 6, 7 carry at their ends rigidly connected to the arms pressure plates which form the stop surfaces 12, 13 which are provided with corrugated, interlocking teeth 16, 17.
  • the tooth engagement ensures a uniform and constant engagement even if the supporting forces caused by the hydraulic devices 10, 11 or the friction occurring at the articulation points 19, 20 should be different.
  • the support arms are constantly acted upon by a resilient return force which changes the angle between the Support arms and the longitudinal axis of the vehicle is aimed to reduce. This restoring force can also be generated hydraulically in the cylinders of the devices 10, 11.
  • the abutment surfaces 12, 13 abut one another (FIG. 1).
  • the angle between the support arms lying on the inside of the curve and the longitudinal direction of the vehicle increases while they separate from one another on the other side (FIG. 2 on the right).
  • the position of the support arms is determined by stops 14, 15, against which the support arms are placed under the return force. They then take the same angle to the vehicle's longitudinal axis if they are of the same length. In any case, their stop surfaces are then at an equal distance from the articulation axis 5.
  • the stops 14, 15 are thus positioned such that the teeth of the stop surfaces 12, 13 find the correct engagement again when the vehicle parts return to the straight-ahead position.
  • the toothing can optionally be reduced to one tooth in one pressure plate and to 2 teeth in the counterpressure plate interacting with it.
