ABSTRACT:
The specification discloses a three-wheeled vehicle with a steering mechanism configured and arranged to provide driver-controlled wheel and body lean as the vehicle is making a turn. A cradle is rotatably mounted at the front of the vehicle for rotation about an axis generally longitudinal relative to the body. An axle connected to the cradle is perpendicular to the axis of rotation of the cradle and a spindle is pivotally connected to each end of the axle. A wheel is rotatably mounted on each spindle. A tie rod pivotally connected at its ends to the spindles is held in a selected position about the axis of the axle by a tie rod linkage. A coupler rotatably connects the linkage to the body. The linkage is also rotatably connected to the axle for rotation about an axis perpendicular to the axle to move the tie rod laterally. When the linkage is disposed to hold the tie rod forward of the axle, a force causing rotation of the movement of the tie rod laterally produces a conventional turning effect. When the linkage is disposed to hold the tie rod vertically above the axle, movement of the tie rod laterally causes the body to rotate about its connection to the cradle by virtue of the coupler, and causes the wheels to lean, producing simultaneous wheel and body lean. Locating the linkage to hold the tie rod in an intermediate position produces a combined leaning and turning effect.
