The rocker arm (8) comprises a first pivot axis (12), which extends transversely to the longitudinal extent of the vehicle (1), wherein a first torsion element (14) is rotationally fixed to the first pivot axis (12) and which first torsion element (14) is arranged to be fixedly fastened in the side of the vehicle body (10). A support device (11; 111) is arranged to cooperate with the rocker arm (8) to relieve the first torsion element (14). The invention also relates to a tracked vehicle (1) for such a suspension system (2, 102).
