Abstract
A mechanical assembly which enables multi-track vehicles to lean into turns and return to a neutral position thereafter.
Claims5
A lean steering truck comprising:
- an attachment plate;
- a torsion assembly 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 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 point at which the second swing arm is coupled to the torsion assembly.
