Vehicle with actively adjustable axle system
First Claim
1. A vehicle capable of traveling over uneven terrain with a load, said vehicle comprising:
- a frame having a front end, a rear end, and a fore-aft axis extending therebetween;
a body mounted to said frame;
an adjustable axle assembly mounted to said frame such that said adjustable axle assembly is aligned substantially orthogonal to said fore-aft axis;
a pair of wheels rotatably mounted on the ends of said adjustable axle assembly such that said wheels are aligned substantially in parallel and are thereby capable of facilitating moving interaction with the ground;
at least one supplemental ground-interacting apparatus mounted to said frame such that each said supplemental ground-interacting apparatus cooperates with said pair of wheels to thereby maintain clearance between both said frame and said body and said ground;
an actuation system capable of mechanically adjusting said adjustable axle assembly to thereby adjust the fore-aft position of said pair of wheels relative to both said frame and said body; and
an electronic controller mounted to said body and electrically connected to said actuation system;
wherein said electronic controller is capable of communicating electrical control signals to said actuation system to thereby adjust said fore-aft position of said pair of wheels as necessary to actively maintain the fore-aft stability of said vehicle.

Abstract
A vehicle with an actively adjustable axle system suitable for traveling over even or uneven terrain with a load is herein proposed. The vehicle includes a frame having a front end, a rear end, and a fore-aft axis extending therebetween; a body mounted to the frame; an adjustable axle assembly mounted to the frame such that the adjustable axle assembly is aligned substantially orthogonal to the fore-aft axis; a pair of wheels rotatably mounted on the ends of the adjustable axle assembly such that the wheels are aligned substantially in parallel and are thereby capable of facilitating moving interaction with the ground; at least one supplemental ground-interacting apparatus mounted to the frame such that each supplemental ground-interacting apparatus cooperates with the pair of wheels to thereby maintain clearance between both the frame and the body and the ground; an actuation system capable of mechanically adjusting the adjustable axle assembly to thereby adjust the fore-aft position of the pair of wheels relative to both the frame and the body; and an electronic controller mounted to the body and electrically connected to the actuation system. In such a configuration, the electronic controller is capable of communicating electrical control signals to the actuation system to thereby adjust the fore-aft position of the pair of wheels as necessary to actively maintain the fore-aft stability of the vehicle.

20. A vehicle capable of traveling over uneven terrain with a load, said vehicle comprising:
-
a frame having a front end, a rear end, and a fore-aft axis extending therebetween;
a power source mounted to said frame;
a body mounted to said frame;
an adjustable axle assembly mounted to said frame such that said adjustable axle assembly is aligned substantially orthogonal to said fore-aft axis;
a pair of wheels rotatably mounted on the ends of said adjustable axle assembly such that said wheels are aligned substantially in parallel and are in mechanical communication with said power source for thereby facilitating moving interaction with the ground;
at least one supplemental ground-interacting apparatus mounted to said frame such that each said supplemental ground-interacting apparatus cooperates with said pair of wheels to thereby maintain clearance between both said frame and said body and said ground;
an actuation system capable of mechanically adjusting said adjustable axle assembly to thereby adjust the fore-aft position of said pair of wheels relative to both said frame and said body;
at least one attitude sensor mounted to said frame and capable of sensing the attitude of said vehicle; and
an electronic controller mounted to said body and electrically connected between each said attitude sensor and said actuation system;
wherein each said attitude sensor is capable of communicating electrical vehicle attitude information signals to said electronic controller; and
wherein said electronic controller is capable of communicating electrical control signals to said actuation system to thereby adjust said fore-aft position of said pair of wheels as necessary to actively maintain the fore-aft stability of said vehicle.
