Steering mechanism for three-wheeled vehicles

A three-wheeled vehicle comprising, in combination:

• an elongate frame member including a planar web normally carried in a substantially horizontal position for supporting a driver-passenger, said frame member having a longitudinal axis of rotation about which it may turn enabling said planar web to assume positions angled relative to the horizontal,
• a front wheel journalled in a pair of bearings adjacent to front end portion of said frame member,
• a rear axle assembly journalling a rear wheel at each end thereof, the diameter of the two wheels of said axle assembly being greater than the diameter of said front wheel,
• a pivot post fixed to and extending rearwardly and upwardly at an angle with respect to a rear end portion of said frame member,
• a sleeve bearing fixed with respect to a central portion of said axle assembly, said pivot post being journalled in said sleeve bearing,
• the position of said front wheel bearings in said vehicle being below the position of said sleeve bearing so said axis of rotation of said frame member is higher in the back of the vehicle than in the front whereby, upon the driver-passenger seated upon said frame member shifting his weight to either side, said axle assembly will be moved for turning of said vehicle in the direction of said weight shift,
• and a back rest located behind said rear end portion of said frame member rigidly fixed to said rear axle assembly to move in unison therewith and independently of said frame member enabling said driver-passenger to control movement of said axle assembly by pressure of his back upon said back rest.
