| 1. A tilting suspension system for a vehicle having three wheels and a frame, the system comprising:
two sets of control arms, each set of control arms being adapted to be pivotally connected to one side of the frame;
an upright pivotally connected to each set of control arms, each upright having a rotatable hub adapted to allow one of the
wheels to be mounted thereto;
two rocker arms adapted to be pivotally connected to the frame;
a control link pivotally connected to each of the rocker arms, such that pivoting of one rocker arm causes corresponding pivoting
of the other rocker arm;
a link member operably connecting each rocker arm to a corresponding upright, such that pivoting of each rocker arm causes
corresponding movement of the uprights; and
an actuator configured to selectively pivot the rocker arms;
wherein actuation of the actuator pivots the rocker arms, thereby causing the frame to rotate about a generally longitudinal
roll center and causing each upright to rotate about a generally longitudinal axis; and
wherein the actuator is connected to one of the rocker arms.
