Patent ID: 6938907

Claim:
A vehicle comprising: a leanable platform for supporting a rider and having front and rear wheel assemblies; and said wheel assemblies comprising a pair of parallel wheel hub carriers arranged on either side of a longitudinal frame member supporting said platform; a linkage connecting said wheel hub carriers to said frame member so that said wheel hub carriers lean in unison with said frame member, said linkage including a first suspension beam extending between said wheel hub carriers and pivotally coupled to said frame; and a steering mechanism coupling said wheel hub carriers to said frame member; said steering mechanism comprising a cranked steering arm pivotally coupled to said frame member at a mid portion of said steering arm and to said wheel hub carriers at respective ends of said steering arm; and each hub carrier being coupled to one end of said first suspension beam and one end of said steering arm through respective universal couplings mounted on said hub carriers on a common shaft in a fixed fore and aft relationship so that as said frame member leans said steering arm pivots about said frame member and pulls said wheel hub carriers through a steering angle dependent on the angle of induced lean.
