Abstract

A dolly wheel assembly (10) for a vehicle (170) includes a dolly wheel (12) and a dolly wheel spindle (18) fixedly secured to the dolly wheel such that the dolly wheel and the dolly wheel spindle rotate together as a single unit. The dolly wheel spindle is in communication with a dampening device (30) so as to apply a resisting force to the dolly wheel spindle. Application of the resisting or braking force restricts or prevents free rotation of the dolly wheel about an axis defined by the dolly wheel spindle. The dampening device is in communication with a controller (46) which causes the dampening device to apply the resisting or braking force or to remove application of the resisting or braking force upon demand to satisfy a variety of different conditions encountered with the vehicle operation considering functional implication of the dolly wheel assembly.
