ABSTRACT:
Damping of the bounce in elastomeric tires is desirable to eliminate the tendency of a machine, such as a loader, to lope or bounce when carrying a load for a distance. The subject invention substantially reduces the lope or bounce by filling the cavity or closed chamber of a tire of a wheel assembly with a liquid, mounting an accumulator to a rim, and controllably interconnecting the closed chamber and the accumulator. By controlling the rate of fluid flow between the closed chamber and the accumulator, the elastomeric tire retains some resiliency while forcing the springs and shock absorbers of the machine to control the tendency for the machine to bounce or lope.
