Abstract
In some aspects, an endless track for traction of an off-road vehicle (e.g., an agricultural vehicle, an industrial vehicle, a construction vehicle, or a military vehicle) includes an elastomeric belt-shaped body having an inner surface for facing wheels of the vehicle and a ground-engaging outer surface. The endless track also includes elastomeric lugs, such as drive/guide lugs projecting from the inner surface and/or traction lugs projecting from the ground-engaging outer surface. The elastomeric lug may have a material defining an arrangement of zones of different materials (e.g., different elastomeric materials) to exhibit a desired variation of a material property (e.g., a modulus of elasticity) across the arrangement of zones of different materials. A zone of the elastomeric lug may have a dedicated function, such as a wear indicator zone. An elastomeric drive lug can include an uneven drive surface for engaging a drive member of a drive wheel.
