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).

Abstract: The invention relates to a drive unit for a tracked vehicle such as a tracked forwarder. The drive unit comprises a track support beam, at least one drive wheel, a set of support wheels and an endless track, said at least one drive wheel being arranged to drive said endless track running over said at least one drive wheel and said set of support wheels. The drive wheel and the support wheels are rotatably attached in said track support beam. The drive unit further comprises an electric motor attached to said at least one drive wheel and integrated in said track support beam, and a track support beam integrated lubrication system comprising a pump unit arranged for pressurized supply of lubricant to parts of the drive unit in need of lubrication.
