Abstract: Described is a track assembly for a tracked vehicle that comprises a track support beam configured to support road wheels, a drive wheel member, and a drive arrangement for drive wheel member operation and an endless track disposed around said road wheels and drive wheel member. Said drive arrangement comprises a motor device for driving said drive wheel member, a transmission device for transferring torque from said motor device to said drive wheel member and a brake arrangement for braking the drive wheel member. Said drive arrangement is configured to be coaxially arranged relative to a centre axis of said drive wheel member. A bearing configuration is arranged in said track support beam, said drive arrangement configured to be journaled in bearings to said bearing configuration for allowing rotation of said drive wheel member relative to said track support beam and for supporting said drive arrangement.

Abstract: The present invention relates to a ground engaging device (G) for an endless track (E) of a tracked vehicle. The ground engaging device is attachable to the outer side of said endless track (E). The ground engaging device (G) comprises an engagement member (10) configured to be arranged in connection to the outer side (Ea) of the endless track (E). The ground engaging device (G) further comprises a fastening arrangement (A) for attaching the ground engaging device (G) to the endless track (E) so that the engagement member (10) is positioned in connection the outer side (Ea) of the endless track (E). The fastening arrangement (A) comprises a adjustment device (D) configured to allow self adjustment of the position of said engagement member relative to the endless track (E) based on pressure against the engagement member (10) towards the endless track (E). The present invention also relates to a tracked vehicle.
