Patent ID: 7967096

Claim:
A lean steering truck comprising: an attachment plate; a torsion assembly including a torsion hanger housing rotatably coupled with the attachment plate and providing resistive force against rotation in a first plane from a defined neutral position; a first swing arm rotatably coupled to the torsion assembly such that the first swing arm is rotatable in a plane other than the first plane of rotation of the torsion assembly; a first control arm coupled to the first swing arm assembly at a location on the first swing arm distal to a point at which the first swing arm is coupled to the torsion assembly; a second swing arm rotatably coupled to the torsion assembly such that the second swing arm is rotatable in a plane other than the first plane of rotation of the torsion spring assembly; and a second control arm coupled to the second swing arm assembly at a location on the second swing arm distal to a point at which the second swing arm is coupled to the torsion assembly.
