Tracked vehicle comprising a tiltable suspended track assembly

A tracked vehicle comprising

• a vehicle body,
• at least one track assembly and
• a suspension device for suspension of said track assembly to said vehicle body of said tracked vehicle,
• said track assembly comprising
• a track support beam comprising a first element comprising a first fastening point and a second element comprising a second fastening point, wherein the first element and second element project from an upper portion of the track support beam,
• a plurality of road wheels,
• at least one drive wheel, and
• an endless track,
• said track support beam being arranged to support said at least one drive wheel and the plurality of road wheels, said endless track being disposed around said at least one drive wheel and the plurality of road wheels, said suspension device comprising
• two pendulum arms which at one end are rotatably attached to a respective fastening point in said vehicle body and at the other end are rotatably attached to one of the first or second fastening points of the track support beam of said track assembly, wherein said suspension device comprises
• a crank throw configuration for a first pendulum arm of the two pendulum arms for allowing a distance change between the respective fastening point in the vehicle body and the first or second fastening point of the track support beam in the track assembly of the first pendulum arm, and
• a suspension configuration for damping the movement of the track assembly relative to the vehicle body and/or for controlling the position of the track assembly relative to the vehicle body, wherein the suspension configuration comprises
• a first hydraulic cylinder rotatably attached to the crank throw configuration about a first axis of rotation at the first or second fastening point of the track support beam in the track assembly of the first pendulum arm, and
• a second hydraulic cylinder rotatably attached to the track assembly about a second axis of rotation at the first or second fastening point of the track support beam in the track assembly of a second pendulum arm of the two pendulum arms, wherein the first axis of rotation and the second axis of rotation are perpendicular to a plane extending in a longitudinal direction of said track assembly,
• so as to allow a tilting movement of the track assembly, including said at least one drive wheel and the plurality of road wheels, relative to the vehicle body in the plane extending in the longitudinal direction of said track assembly essentially orthogonal to the transversal extension of said track assembly.
