    Abstract: The invention relates to a tracked vehicle comprising a vehicle body and a track assembly pair. Said track assembly pair is arranged to suspendedly support said vehicle body allowing relative movement between said vehicle body and each track assembly (21) of said track assembly pair. Each track assembly (21) comprises a track support beam (22) configured to support a plurality of road wheels (23, 23a), a drive wheel (24), and a motor (110) for operating said drive wheel (24), an endless track (25) being disposed around said road wheels (23, 23a) and drive wheel (24). Said motor (110) is fixedly arranged to said track support beam (22). Said motor (110) is arranged in connection to the drive wheel (24) such that a motor axle essentially coaxially coincides with a centre axis (Z) of the drive wheel (24).
