摘要:
An endless track for providing traction to an off-road work vehicle (e.g., a construction vehicle, agricultural vehicle, or forestry vehicle). The endless track has a longitudinal axis and comprises an inner side for engaging a drive wheel of the off-road work vehicle to move the endless track and a ground-engaging outer side for engaging the ground. The ground-engaging outer side comprises a tread pattern characterized in that, when the off-road work vehicle moves on the ground, the tread pattern produces lateral traction force components acting laterally on the endless track such that a resultant of the lateral traction force components is a net non-null lateral force acting on the endless track in a lateral direction generally perpendicular to the longitudinal axis. For example, the net non-null lateral force can be used to oppose undesirable side loads and/or tendencies for lateral movements that may be experienced by the endless track due to intrinsic mechanical imbalances which may arise in the vehicle (e.g., “toe-in”, negative camber, etc.), motion of the vehicle on the ground (e.g., if the vehicle turns almost exclusively or significantly more often on one side), and/or use of a working implement with which the vehicle may be equipped.
