Test of Power Steering Pumps as Hydrostatic Drive

[thiago497150]

You can try one pump and 2 motors in parallel in each wheel. In parallel you have a mechanical advantage

Theres a patent on this drive for pedal bikes - I was working on something similar and found the patent recently. Remember to allow for coasting... you'll need some sort of bypass valve, etc.

Not pointless at all. Thats how inventions and new technology is developed. Good video

Hey man, just wondering... im interested in making a hydrostatic drive gokart. Will this system work in reverse? Id be running it with a 980cc 24hp twin Onan.

Cheers

Like the vid. I'm lookin at buildin a motorized hydrostatic skateboard and have been havin troulble findin some cheap pumps. Thanks for the idea. what are you lookin to build?

So, why will it not work the other way around, powering the small pump and using the other for drive?

[RCFLYER83]

I have been thinking of building a system like this to power somthing for awhile. I was thinking you could put a bypass pipe with a valve, connected between the two hoses with a couple of t's, and it would function just like a clutch. That would be pretty neat for a mini bike. Hydroclutch!!!!!

You have to size the pumps based on a combination of their input RPM, pressure rating, and GPM (Gallons Per minute). Then figure you're going to lose at least 10% of input power and RPM under high load. How do I know? I looked into this stuff about five years ago. Still am actually. You CAN mix and match various pieces for a custom application, but to be successful you'll have to do some basic calculations.

jfbrink- what if you use two identical pumps like the honda one? I have been interested in the same.... powered by a Honda GC160 5hp.

[jfbrink]

The problem with two identical pumps is that you gain no mechanical advantage. Hydraulic systems can be "geared up" or "geared down" by varying the size of the pump relative to the motor(s). So, two of the same Honda P/S pumps would be like a substitute for a 1:1 sprocket set.

pointless??

[jfbrink]

I would say *almost* pointless.

This is great. This is a good experiment. I like your thinking bro. I agree with this.

[ilgalane]

is cool bro! i `wondering what you trying to built?but is great idea! thanks for sharing
