Liquid propshaft (part 2): we got it to work!

[@thomasheer825]

Have a simple suggestion since I worked with hydraulics, even though was a electronics/electrical specilist for several decades. Simply install a variable displacement pump on the engine. With a wobble plate pump in the neutral position no oil flows, with maximum deflection of the wobble plate you have maximum flow. Many industrial and aguriculture systems use this method and it works fine. What you are having happen is basically hydraulic lock situation. The only way your system will work is WFO. With a variable displacement pump you would set the engine to a set speed and swivel the pump to change the hydraulic flow. We had one machine that used a fix displacement pump and a preportion valve system to vary the rotational speed, it was a continual pain in the ass while the wobble plate units ran trouble free.

[@pflaffik]

Such a part could not be pulled off an old excavator but from a more modern agricultural tractor, and not a cheap one. Too expensive.

[@stefandr5252]

That would be a better solution indeed, a smaller pump also works out in this situation. 100cc is ridiculous

[@thomasheer825]

@@pflaffik Sorry it is a common item for motion controls in many industrial applications. Can dig around in several industrial/agraculture junk yards around her and get them at a reasonable price. If you want it to work you have to spend money. Practically EVERY compact tractor employs this method for drive system and another pump for the other systems, often these pumps however have a compound arrangement where the variable displacement pump is for drive and the other is for systems.

[@DaveWithMS]

If you put the pump directly on the engine, you should have had the drive motor connected to the input of the transmission. If you run the drive motor on the rear end, you should have the pump on the output of the transmission.

[@Chris_Garman]

The pump needs to be maintained at the correct RPM. The more direct the drive the better.

The pump should be on the transmission

The pump should definitely be powered off the rear of the transmission. It would only be removing the driveshaft from the equation but

[@otm646]

15:34 the point is that you have a near infinite range of ratios within each of those gears. The transmission simply allows you a broader range of road speeds because the pumps you've selected aren't infinitely variable in displacement.

A pressure relief valve for the system should let you keep it pressurized and just run with the hydraulic valve.

[@matthewperlman3356]

The control lever is basically working like a clutch. I would recommend hooking it up to a clutch pedal such that it engages with the pedal up and releases when the pedal is pressed down. that should make the coordination easier, as it would close to what you are use to. Also having the pump direct to the engine output would reduce losses.

What your ideas have common in this project. Turbo from semo dosen't work in Lada, engine dosen't have power torun it, so there is no pressure generating. Sorry. I think EVERYONE knows that but.. now you too know it.

[@blahorgaslisk7763]

Having had a boat with hydraulic drive I have some insight into what's possible. Now it was some years back, but I remember that the hydraulic pump and motor actually was the same models. Turns out they can work either way. Another thing was that the valve used had three circuits. In "neutral" is recirculated the oil from the hydraulic motor to the oil reservoir. In forward the oil circulated through from the pump to the motor and back to the oil reservoir. Finally in reverse it simply switched the input and the out put of the hydraulic motor. The valve had some overflow so it was possible to carefully moderate the prop speed without changing the throttle. Or you could brutally slam the hydraulics from full forward to full back and the boat would rattle and shake as the water churned into white froth behind the boat. This last was scary and put a lot of stress on the hull. It's something that's almost impossible to do with a mechanically coupled driveshaft, but the hydraulics was just so darned robust. The boats previous owner was a retired Navy Commander and he drove that boat as if it was one of his corvettes. Full forward and full back, nothing in between... I never used it anywhere near as hard, but it was good to know just what it was capable of if need be. What I'm getting at is that it shouldn't be that hard to hook it up so you have a reverse. Another thing is you need an oil cooler if you want to be able to drive it for any length of time. When the hydraulics heat up enough it will foam and you don't get anywhere. I also think you need to figure out the RPM of that pump. It really shouldn't be to high as that generates more friction in the hydraulics lines which heat up the oil even more. Get the RPM down somewhat and it shouldn't heat up to much. And then there's the speed of the hydraulic motor. If it's to high you either have to get some kind of gearbox in there, or perhaps you can do with a torque converter. That last might be a good option if you have one or can get one for cheap. When a hydraulic drive is used in a boat the prop and the sea acts as your torque converter...

[@MichaelThomas-wb2xu]

Try this on a front wheel drive car so you have both, types working together...and a rubber flex coupler at the diff would have turned smoother. On a lot of heavy equipment the throttle is run wide open and the speed is controlled by the lever, that way the system always has full power.

[@jwalster9412]

Most cars arnt designed to maintain high revs for a long time, and will overheat, or become shrapnel.

What do you mean can't backup is inconvenient. When I bought a VW Bug in high school the transmission had lots of problems in Reverse so I tried not to use it.

On a different Bang! no third gear so we drove ~200 miles in 2nd down I5 in California from Humboldt county to Silicon Valley area. Once driving a van in Santa Cruz the shift linkage broke so I was stuck in 3rd. Starting up on a hill in 3rd gear is interesting. I remember air powered power tools used to be very popular although more are battery electric now. What about four wheel drive are power? Stupid idea. In swampy area in USA people have Fan Boats with the engine driving a big FAN to push the boat because propeller gets tangled up and hits too much stuff.

No Reverse? Can’t you simply move the lever forward, to reverse the hydraulic motor? Here’s an idea: now that you have a working hydraulic system, try removing the rear axle and mounting two hydro motors, one for each rear wheel. Then you could experiment with hydrodynamic thrust vectoring - steering with the rear wheels.

I was expecting him to push the lever forward to go backwards and was surprised when he didn't even try it. I'm not a hydraulic expert, but I've worked on several different hydraulic systems on tow trucks and construction equipment, and every one I've touched reversed when the handle was moved the opposite way.

@@dadigitechman You're right, I have no idea. I only know about the systems I have personally worked on.

At least in the USA. I'm sure other countries have similar organizations.

[@gabiold]

There are adjustable flow pumps, for example an axial piston pump where the stroke is controlled by a swashplate. Those can be adjusted from zero-max. You could control the pump with the lever or gas pedal, while keeping the engine at some efficient RPM by other means, a governor for example. An interesing concept would be how to control this thing for maximum efficiency while having some decent final speed too.

[@Bot.number.69420]

Using variable volume pump instead of valves would be like hydrostatic transmission. They just pump more per revolution to go faster. Also could using a governor like on lawnmowers to keep revs stable could help. One could make massive project out of this.

@Karl with a K it would be very interesting to see the difference in efficiency compared to a driveline with gearbox, the only trouble is that you would need a variable displacement pump as to not 'destroy' the unused energy with a valve (engine will have insufficient torque on low rpm to get the car moving). Could be a closed loop system as well, contrary to what is shown in the video.

Place that system with front wheel drive. Connect the pump to flywheel from motor and set a connection to throttle and it would be less stress to shorter pressure lines and have the hydroloic oil tank in trunk that would be hooked up to a oil cooler that would be more efficient to the car.....and shorten the lever where your throttle controls the speed

Along with all the great suggestions I have to add, try using a bigger engine. I know Ladas are tough cars to kill but those little 4cyl just dont have any torque even without the experiments. Love you guys, long time viewer here.

[@bobpowers9862]

Maybe put the pump in place of the transmission, but leave the clutch in. You start with the clutch depressed, so the hydraulic pump is not spinning. Then release the clutch to run the pump. A reversible hydraulic motor takes care of reverse. You just pull the lever the other way. You might be able to salvage one from a mini excavator machine-- the one that spins the whole cab would do; it's not high RPM, it's reversible, and it's got plenty of torque. Nice build, regardless.

[@giggiddy]

Would love to see what a properly matched pump/ lines would do. I've always wondered.

Please try again with a little better (more robust? setup as you are definitely on to something!!! Please!!!!!

[@1one3_Racing]

Because of the nature of hydraulic pumps and the thermal properties of the oil you can only set a very limited speed range. Either you can do 0 to around 40kmh or 30-100kmh. Unless you ran the drive motor on the transmission and ran it like a regular car. Then it would be no different from a regular car except that it would run a hell of a lot hotter.

[@nickoloes]

Liquid driveshaft would be an appropriate title

[@nuttyDesignAndFab]

the problem is your valve block; its not meant to run stuff like this, its meant to run reversible cylinders. This means that in the transitional region (from off to forward, or off to rev) it creates a ton of extra restriction, but doesn't help "slip" the engine with relation to the wheels. When you fully open it then the restriction goes away but now you're fully in gear so again its hard on the engine. This is why this system only works when you rev it then slam it into forward, but struggles so much when you try to ease into it. its hard to say what the gear ratio is but it may or may not be correct. I think you would have better luck with a clutch between the engine and the pump, and then running the hydraulics from the pump to the motor without any valve.
