Abstract
An articulated vehicle such as, a bus having a lead car and a trailer coupled to each other through the intermediary of a central ball joint in the central longitudinal plane of the vehicle. The central ball joint transmits only horizontal forces between the lead car and the trailer and can therefore be supported through comparatively lightweight elements which require little space. The transmission of vertical forces between the lead car and trailer is effected through arms located on both sides of the joint. A cardan shaft is extended along the longitudinal center plane of the articulated vehicle from the lead car to the trailer.
Claims6
In an articulated vehicle, such as a bus, including a lead car and a trailer;
- a central ball joint arranged in the central plane of the vehicle coupling said lead car to said trailer;
- the improvement comprising:
- a shackle pivotally mounted about a horizontal transverse axis at the trailer and connecting said trailer to the ball joint;
- a pair of arms being arranged respectively, on either side of the central ball joint on the lead car and on the trailer for rotation about a vertical axis and further ball joints on each side of the vehicle for interconnecting the arms of the lead car and of the trailer, said further ball joints being arranged at the same level.
