gave up on multi gear "gear motor". to much space being taken up by the gears.

before giving up, drew up one manifold plate. to hold "check valves" to deal with "suction" (negative psi), and max PSI. only drew one of the 2 up. and inserted 12 of them. if i did not give up. would of went back and redone the neg and max PSI check valves. to make everything into a smaller package. also would of finished the "valve" manifold. 6 gear ratios built into it. just needed something to physically turn it. was running out of space of were i wanted to place wet discs. and partial reason of giving up multi gear "gear motor" setup.
i did setup some were plates. (orange in color) that fitted up against the valve. but was not really happy in how the groves were made for were the wear plates fitted.
================
================
quickly built a generic hyd axial motor. and added total of 3 rings. that could allow any were from 1.5 cubic inches up to 30 to 42 cubic inches of displacement per full single rotation. and allowed up to 7 gear ratios. pending on which of the 3 rings of cylinders/pistons/rods were fed hyd oil. able to reach about 70mph at 50 GPM,
tempted to press upwards of 100gpm, but internal diameter of hoses that would run from main frame of SSTT down to hyd motor and all the passage ways. would cut 3000PSI coming from main hyd pump on SSTT down to about 1500PSI. using 0.5" inch hose. 1" might allow upwards of 100GPM but still friction loss of hyd oil. running through pipes be nailing things.
i bounced back and forth way to many times between excel and autodesk. trying to figure out how to maximize amount of cylinders, to reach smallest diameter, and largest cubic inches displaced per full revolution. and just never came up with anything meaningful. a good portion was limitation. of physical length a piston/rod could be made, and diameter of it. my thoughts are diameter of piston/rod need to be smaller than the length of the piston rod. or i would end up with piston wanting to flip upside down on me. i was already reaching enough inches. that i reasonably assumed i would quickly go over 12" width tire. forcing me to go up with smaller diameter cylinders / pistons / rods. ended up massing way to many pieces.

nothing special. was hoping to get 3 swash plates or rather 3 rings, that each had a single hump. but never got that far.

gave up on above fairly quickly. when idea of some locking gears. came to mind, that might prove more promising. and operate much like "disc brakes" you find on your regular car / truck. 12" outside diameter 11" inside diameter. teeth 1" tall, with max separation of 1.75" inches. gives approx 26 cubic inches per full revolution. and applying brakes if you will, will decrease down to 0 cubic inches per revolution.

the "lite blue" and "dark blue" for outside the 2 gears. i'am still debating about. at moment it resembles a generic "gear motor" or "gear pump" casing around the gears. but that may change fairly quickly.
hhmmsss squirrel cage fan, i suppose kinda of a turbine setup.
why not. off set the teeth angle. from center, to a different angle. it would reduce amount of teeth possibly. hhmmss more internal leakage *big frown* but. would it provide better overall torque in low end RPMs as in creeper gears, and higher top MPH? hhmmsss. what about dead stop, and moving.
still need to figure out, how to apply forward / reverse. and how to deal with inlets/outlets. let alone figure out were to place springs, and how to get everything to work
