Abstract
A tread pattern for a vehicle track, such as an endless track for earth-moving equipment, comprises a plurality of blocks. Each block includes two lateral traction portions extending in substantially opposite directions. The two lateral traction portions are longitudinally aligned and each define a pair of walls defining a plurality of steps. In some examples, each lateral traction portion may define an L-shape. For example, the lateral traction portions of each block may define a protrusion to define the “L” shape, and, in some examples, the protrusions may extend in opposite longitudinal directions. In some examples, the lateral traction portions of each block may be the same shape, where one lateral traction portion may be oriented at about 180 degrees relative to the other lateral traction portion.
