Abstract: A structure for enabling independently suspended wheels to lean with vehicle hull, which comprises a linkage mechanism and two suspending mechanisms.

Abstract: A frame and suspension for a vehicle provides automatic lean and alignment. The lean is determined by force sensors, the speed and/or the angle of turn and is provided by actuators in the suspension in accordance with a predetermined protocol in an electronic control unit (ECU). The protocol also provides shock absorption by rapidly tracking a contour of a surface on which the vehicle rides. The suspension is provided by a plurality of arm assemblies each including a lower arm, an upper control arm, and an actuator motively connected to the lower arm and to the upper control arm. The arm assemblies are pivotally connected to the frame on a common axis. The arm assemblies generally form parallelograms and are actuated in concert to remain generally parallel to each other through a range of angles to adjust the lean of the vehicle. The arm assemblies are also actuated independently of each other to accommodate variations in the contour.

Abstract: A suspension system for a vehicle is provided that allows for the vehicle body to be tilted wherein the tilt is controlled by the operator's legs in a manner that greatly enhances the stability of the vehicle while producing a fun vehicle to operate. Further, the bottom member of the suspension system is structured in a manner that provides storage capacity for installation of heavy items such as battery banks in order to preserve a lowered center of gravity for the vehicle. The tilting suspension may be used in the context of three-wheeled vehicle having a single rear drive tire and two forward wheels, but apply equally to a four wheeled vehicle as well as to water craft operating on pontoons or snow vehicles operating on skis.

Abstract: A “super fuel efficient”, safe, low-cost and yet high performance 4-wheeled vehicle is configured with motorcycle wheels and tires having continuous radius tires and of outside diameter (20-26 inches). A special configuration of the invention permits a 4-wheeled vehicle to naturally camber while engaging a corner, or while maneuvering on a slope. Integration of a “short-cycling”, low storage mass hybrid drivetrain into the vehicle, and further, an exhaust heat energy recovery system, secures the efficiency opportunity.

Abstract: Enhanced vehicle handling is achieved by the improved suspension systems constructed in accordance with aspects of the present invention, in which not only do the roll couple and jacking couple oppose each other, thereby causing the body roll to counteract the jacking effect, but also the pitch couple and the pitching couple oppose each other, thereby causing the body pitch to counteract the pitching effect. This results in the improvement of the cornering traction of the vehicle, the braking traction of the vehicle, the acceleration traction of the vehicle (especially in a front-wheel-drive vehicle), the simultaneous cornering and braking traction of the vehicle, and the simultaneous cornering and acceleration traction of the vehicle.

Abstract: The invention is a suspension system for a three (3) or more wheeled vehicle, which vehicle tilts from the vertical plane during operation in a manner like that of a motorcycle. The suspension system divides the vehicle into two parts.
