<p>This cab suspension unit (100), for a vehicle having a chassis (51) supporting a cab (1), comprises a rotating part (151) and a static part (101), one of said rotating (151) and static parts (101) having means for connexion to the cab (1) and the other one having means for connexion to said chassis (51). The rotating part (151) is arranged to rotate around a generally horizontal axis (Y151) due to the vertical movements of said cab (1), but one element having elastic properties is arranged so as to cooperate with both parts to resist to a relative rotation between the two parts. One friction arrangement (660, 780) comprising a rotating sliding surface (662, 782) and a static sliding surface (661, 781), connected to the corresponding parts (601, 701), with at least one of the sliding surfaces connected to the corresponding part by an elastic element (663, 783). The sliding surfaces are arranged such that, when the rotating part rotates, the sliding surfaces slide one against the other and the elastic element is increasingly compressed, thereby increasing the contact forces between the two sliding surfaces.</p> |
