Lean-induced steerable wheel assembly

A vehicle comprising:

• a leanable chassis platform for supporting a rider and having front and rear wheel assemblies;
• and
• at least one of said wheel assemblies comprising a pair of parallel wheel hub carriers arranged on either side of a longitudinal frame member;
• a linkage connecting said wheel hub carriers to said frame member so that said wheel hub carriers lean in unison with said frame member;
• and
• a steering mechanism coupling said wheel hub carriers to said frame member so that an induced lean on said frame member steers said wheel hub carriers through a steering angle dependent on the angle of induced lean.

A lean-induced steerable wheel assembly, comprising:

• a pair of parallel wheel hub carriers arranged on either side of a leanable longitudinal frame member;
• 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 comprising a pair of upper and lower suspension beams pivotally coupled at their ends to said respective wheel hub carriers and in the vicinity of a mid point thereof to said frame member;
• and
• an elbow member pivotally connected to said frame member at a mid-point thereof and coupled at respective end portions thereof to said wheel hub carriers by universal joints such that as said frame member adopts a lean attitude, said elbow member pulls said wheel hub carriers around a steering axis and thereby steers said wheel hub carriers through a steering angle dependent on the angle of induced lean.
