Abstract
The invention relates to a tracked vehicle () comprising a vehicle body (), at least one track assembly () and a suspension device (S) for suspension of said track assembly () to said vehicle body () of said tracked vehicle (). Said track assembly () comprises a track support beam (), a plurality of road wheels (), at least one drive wheel (), and an endless track (). Said track support beam () is arranged to support said at least one drive wheel () and a plurality of road wheels (). Said endless track is disposed around said at least one drive wheel () and plurality of road wheels (). Said suspension device (S) comprises two pendulum arms () which in one end are rotatably attached to a respective fastening point (P, P) in said vehicle body () and in the other end are rotatably attached to a respective fastening point (P, P) in the track support beam () of said track assembly (). Said suspension device (S) comprises distance adjustment means () which is arranged to allow one or more of: a distance change between said two fastening points (P, P) in the track assembly (); a distance change between the two fastening points (P, P) in the vehicle body (); and a distance change between the fastening point (P, P) in the vehicle body () and the fastening point (P, P) in the track support beam () of said track assembly () of at least one of the pendulum arms (), so as to allow a tilting movement of the track assembly (), including said at least one drive wheel () and plurality of road wheels (), relative to the vehicle body in a plane extending in the longitudinal direction of said track assembly () essentially orthogonal to the transversal extension of said track assembly ().
