A wheel shock absorbing apparatus includes: a hub, one or more bearings
seated within the hub, and an axle. At least two outer end caps, each
with an axle mounting hole and an offset inwardly opening cavity, enclose
the ends of the hub. A springing element is positioned within each cavity
in the end caps, and an inner body unit is located between the outer end
caps. An actuation stud projects from the inner body unit into the
cavities to contact the springing element. Fastening elements secure the
outer end caps together on opposite side of the inner body unit. A pivot
stud allows the respective outer end caps and inner body unit to pivot
with respect to one another, which causes the actuation stud to contact
the spring element, which absorbs shocks as the wheel travels over a
surface during locomotion of a vehicle.
