Abstract: A self-loading tricycle transporter directed to 10-50 ton load ranges having a three-point tricycle type configuration providing superior suspension in terms of natural load contact on any type of surface condition. The tricycle transporter includes a fluid lifting suspension at each of three points. One point utilizes an on-center rotation fluid suspension axle assembly working in conjunction with solid elastomer tires at each end axle beam at the rear that attaches to the underside of the tricycle transporter platform with heavy fluid cylinder at each end. Accordingly, the three suspension points have the capability of being able to lift and lower to accommodate self-loading.

Abstract: A three-wheeled motorized vehicle with a reverse trike or tadpole configuration is described. The vehicle includes a rear frame coupled to a single rear wheel and a front frame that is operatively coupled to a pair of front wheels mounted on opposite sides of the front frame. The rear frame is pivotably coupled to the front frame by a first coupling located along a top portion of the front frame and a second coupling located along a bottom portion of the front frame. The first coupling is located forward of the second coupling to provide a negative rake angle. Handlebars affixed to the front frame pivot the front frame, an engine mounted therein, and the front wheels about the first and second couplings. The location of the first and second couplings also causes the rear frame to lean out of a vertical plane when the front frame is pivoted.

Abstract: A wheel assembly for a small-scale machine includes a pair of opposing, individually-driven wheels, associated motors and possibly one or more gear assemblies. The motors receive separate drive signals from a control electronics subsystem of the wheel assembly. The motors can be connected to the wheels via the gear assemblies. Because the wheels are separately driven, driving the two wheel assemblies at similar or different speeds drives the wheel assembly over straight or curved paths. An orientation assembly allows the orientation of the wheels to the machine to be controllably altered. A height adjusting assembly allows the distance between the wheels and a point on the machine where the wheel assembly is attached to be adjusted. The rotational axis that the wheel assembly rotates about when re-oriented need not pass through either wheel of the wheel assembly. The wheels can be driven by control signals generated by on-board control electronics.

Abstract: A wheel base or mobile platform providing omnidirectional motion and control. At least two offset wheel assemblies are coupled to a platform that supports a load. Each offset wheel assembly has two wheels that share a common axis and a mechanical link that is pivotally coupled to a pivot point on the rigid platform and supports the two wheels in such a manner that the common axis is displaced from the pivot point. The common axis of the wheels is free to rotate about an axis parallel to the planes of rotation of the wheels. The platform may be turned in any direction specified by a user from any instantaneous configuration or velocity in accordance with a method uniquely specifying a torque to be applied to each of the wheels while each of the wheels is in rolling motion.

Abstract: A utility vehicle is provided with a bogey beam on which are mounted the steering axle at the forward end of the bogey beam and the middle axle on the rearward end of the bogey beam. A rear drive axle is supported by the frame of the utility vehicle. The bogey beam is connected to the frame by a pivot assembly defining a transverse pivot axis about which the bogey beam can oscillate. The weight transferred to the bogey beam is proportionately distributed between the front steering axle and middle axle. As a result, the steering characteristics of the steering axle are not impaired by the imposition of a load in the load bed of the utility vehicle, as the middle axle cannot be loaded sufficiently to overpower the front steering axle. The middle axle is rotatably driven by the rear drive axle.
