Abstract
An endless track for providing traction to a vehicle, such as a construction vehicle, an agricultural vehicle or other work vehicle. The endless track has: an inner side for facing a plurality of wheels of the vehicle; a ground-engaging outer side for engaging the ground; a first lateral edge; and a second lateral edge. The endless track comprises an elastomeric body and a plurality of cores at least partially embedded in the elastomeric body. Each core extends transversally to a longitudinal direction of the endless track to provide transverse rigidity to the endless track. The endless track comprises an impact absorber in a lateral edge part of the endless track, the lateral edge part being located between the cores and a given one of the first lateral edge and the second lateral edge. The impact absorber facilitates an elastic deformation of the lateral edge part when the lateral edge part impacts an obstacle on the ground. For example, in some embodiments, the impact absorber may comprise one or more holes which can deform when the lateral edge part impacts an obstacle on the ground.
