Wheel pivot consists of support (8) for pivot unit (7) that can rotate about two articulated joints (9, 10), of which first (9) has at least one degree of freedom to rotate about main axis. Second joint (10) has bearing (33) that has degree of freedom to rotate about main axis and inner and outer rings that can rotate relative to one another and permit rotation about secondary axes perpendicular to main axis as well as movement along main axis. The support comprises a body (11) with first and second arms (12, 13) projecting more or less perpendicular to it and having the articulated joint on their ends. |
