Patent ID: 8469377

Claim:
A method of stabilizing a vehicle during turns, the method comprising the steps of: attaching a truck assembly to an aft portion of a foot support of the vehicle; rolling the foot support about a longitudinal axis of the foot support; yawing an axle of a hanger of the truck assembly having two wheels mounted to opposed end portions of the axle about a pivot axis which is skewed with respect to the longitudinal axis, the axle being oriented traverse to the longitudinal when the vehicle is moving straight forward; during the yawing step, traversing a bearing up away from a low middle portion of a camming surface toward a raised outer portion of the camming surface wherein the bearing is disposed between a base of the truck and the hanger, the camming surface is formed in either the base of the truck or the hanger, and the camming surface has a curved groove defined by a recession between an inner curve and an outer curve with respect to the pivot axis and defines a curved travel path of the bearing equidistant to the pivot axis; and biasing the hanger and the base toward each other such that the bearing is biased toward the low middle portion to stabilize the vehicle.
