Trip to Va Tech #2

[R.I.D.E.]

Here are pictures of the model I built. The outer rim rotates while everything inside the black shaded ring is stationary.

The three photos show 3 postions:

Lowest foreward gear
Neutral
Lowest Reverse (or highest regeneration)gear

Any position between these maximums creates an effectively higher gear. The movements of the adjustable journal are very subtle, but the consequences are dramatic.

If you apply 5000 PSI pressure to each piston as it and its corresponding cylinder pass over the high pressure supply port (in the adjustable journal-not shown in the model). You transfer that force to the outer locating point of each piston. If the cylinder has a surface area of 1 square inch then you would be creating about 800 foot pounds of rotational torque directly on the outermost portion of the rim, on EACH drive wheel.

As the wheel starts to spin and you want to go to a higher gear, you reduce the stroke position and that is all that is necessary to go to a higher gear. Highest gear would be the slightest amount of adjustment from the neutral position.

Sitting still you are in neutral. When you want to accelerate you move the journal to a position that matches the desired rate of acceleration. Regeneration is simply reversing the stroke position. In fact, if you continue to apply that same sroke position the vehicle would actually go backwards after coming to a complete stop.

As you regenerate braking energy and the pressure rises, you simply reduce the stroke position to compensate.

Look at the model and understand it is basically an axle with a hub rotating around that axle. The diameter of the axle is enlarged to about 4 inches to allow an offset hole to be drilled through the axle, which allows the journal and its shaft to pass through the axle for external adjustment as well as providing a rotary valve for supply and return fluid passageways.

Think of it as a "smart" axle, like smart bombs. The smart portion is the 4 rotary cylinders and their pistons and the adjustable journal. The clyinders are highlighted with red paint, while the pistons are silver. Notice the lack of connecting rods, because the pistons and cylinders can each pivot on their respective end locations.

I'll be back later to answer other questions.

Pictures in next post, sorry I chose quick reply.
