Lean-induced steerable wheel assembly
First Claim
Patent Images
1. 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; 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.

Abstract
A lean-induced steerable wheel assembly has a pair of parallel wheel hub carriers arranged on either side of a leanable chassis spine. A linkage connects the wheel hub carriers to the chassis spine so that the wheels lean in unison with the chassis spine. A steering mechanism couples the wheel hub carriers to the chassis spine so that an induced lean on the chassis spine steers the wheel hub carriers through a steering angle dependent on the angle of induced lean.

13. 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. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. 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. - View Dependent Claims (32, 33)
