Abstract
A method and apparatus relating to a driveline and suspension system for a vehicle and, more particularly, methods and systems for driveline-suspension coupling in a narrow multi-track leaning vehicle with three or more wheels and with at least two driving wheels. There are provided graphical and computational methods for determining driveline and suspension geometries for narrow multi-track vehicles, as well as apparatuses including the geometric configurations, and exhibiting improved driveline-suspension coupling behaviors.
Claims19
A method for improving performance of a driveline and suspension of a leaning vehicle having a first driveline, a first rear driven wheel on a first trailing arm suspension, a second driveline, and a second rear driven wheel on a second trailing arm suspension, the suspensions having a shared pivot axis wherein the driven wheels are movable independently of each other over a range of suspension travel, comprising:
- determining a driveline-suspension geometry which results in a substantially constant driveline-suspension coupling over the range of suspension travel, or in a progressively increasing driveline-suspension coupling during a suspension compression during vehicle acceleration, or in a progressively increasing driveline-suspension coupling during a suspension compression during vehicle braking;
- providing the drivelines and the suspensions with the determined suspension-driveline geometry;
- and
- supplying equal driving forces to the driven wheels.
