Abstract
A sprocket wheel of an endless track-type vehicle has a hub and a plurality of sprocket teeth segments fixedly secured to the outermost of the hub to engage a plurality of bushings of an endless track for driving the same. The hub comprises a substantially annular-shaped radially inner part, a substantially annular-shaped radially outer part arranged movably with respect to the inner part by the interposition of a plurality of deformable resilient block segments tightly inserted into an annular space defined by and between the inner and outer parts, and a stopper mechanism for preventing the deformable resilient block segments from an excessive deformation thereof.
