ABSTRACT:
A suspension unit for vehicles comprises a support fastened to a framework of the vehicle and a longitudinal arm, with a rolling member coupled to the arm, rotating relative to it about a transverse first axis. The arm is coupled to the support and rotates relative to it about a transverse second axis which is parallel to the first axis and offset relative to it in the longitudinal direction. Within the arm is a longitudinal cylinder within which slides a piston. A rod is coupled to the piston and to the support. The rod rotates relative to the support about a third axis parallel to the second axis and offset relative to it transversely. The rod rotates relative to the piston about a transverse fourth axis parallel to the third axis. It is pivoted to the piston by a mechanism comprising a slide member that slides longitudinally within the cylinder and is juxtaposed longitudinally to the piston on the same side as the rod. The rod is pivoted to the slide member for rotation about the fourth axis.
