in my humble opinion.. .
you have two solutions, if "the rest of the machine" allows you
a - after the pump and its maximum valves, mount a regulating proportional flow valve (which makes you as an accelerator) and then an adjustable flow divider (which acts as a "steel")
b solution - after the pump and its maximum valves, mountains two proportional flow regulator valves, one for each motor. in practice controls the cart with controls like a bobcat or an old-generation tank. a lever on the side. commanding them both in the same way, go straight, opening one more than the other steering on the right or left
all this if the mechanics allow you to ....[/quote
my idea is pump, max valve, flow regulator, balance valve, distributor a, distributor b, motor and motor b

and the two free... the mountains on a steering wheel or do you leave them free? ? ? ?4 total wheels of which 2 are free and two wheels
well explains what you mean by the balancing valve. . .my idea is pump, max valve, flow regulator, balance valve, distributor a, distributor b, motor and motor b
because I know the flow dividers, who do their job well but send the flow to 50% for each branch, regardless of the load. So... good to go straight, not to dig

then, the free wheels do not have the steering but are free to turn like the shopping cart to mean us, they only serve as support, regarding the valve is that you say 50/50 and for this I put it before the distributors to have the same flow in both, example I need 10 liters for each motor, the pump is 20 liters, with this valve I divide the 20 in2 engines, then 10 in one and 10 to the other. Am I right?and the two free... the mountains on a steering wheel or do you leave them free? ? ? ?

You will go straight unless the valve split tolerance... gear dividers are more precisethen, the free wheels do not have the steering but are free to turn like the shopping cart to mean us, they only serve as support, regarding the valve is that you say 50/50 and for this I put it before the distributors to have the same flow in both, example I need 10 liters for each motor, the pump is 20 liters, with this valve I divide the 20 in2 engines, then 10 in one and 10 to the other. Am I right?
definitely add two overcenters or double-acting block in case you go up or down.my idea is pump, max valve, flow regulator, balance valve, distributor a, distributor b, motor and motor b
the only doubt I have are the losses (any generation of heat) in the flow regulator and in the balancing machine... attention to the temperature of the hour!

That's right! ! !You will go straight unless the valve split tolerance.. . !
and then it will go even more straight...gear dividers are more precise!
could be useful a cbea of the sun hydraulicsdefinitely add two overcenters or double-acting block in case you go up or down.

I'm going straight, okay, but if they start one engine, I'm not going? Don't stay still? Could I send him one forward and one back or not?That's right! ! !

Yeah.I'm going straight, okay, but if they start one engine, I'm not going? Don't stay still? Could I send him one forward and one back or not?
but how do you operate a single engine if you have a flow divider? and how do you convince him to go back?

the flow divider must go before the distributors, then 50% on to and 50% on b and reverse with double effect distributorsYeah.
but how do you operate a single engine if you have a flow divider? and how do you convince him to go back?

but then eliminates the flow dividers and uses two proportional, one per a and one per b
the operator, with the two levers, does as a "flow divider" and you can afford the luxury of gently steering, abruptly, reversing, turning on itself or piffering it seems...

what oil do you use and what is the required passage? or the nominal range of the single engine. . .What are they?

the oil is hydraulic 46, the motor is 200cc to 80 bar 10 l/m, I would not use electrical components because the motor I have is tear and I do not have battery and all the restwhat oil do you use and what is the required passage? or the nominal range of the single engine. . .

10 l/min is enough for your two engines? Did you do the calculations?the oil is hydraulic 46, the motor is 200cc to 80 bar 10 l/m, I would not use electrical components because the motor I have is tear and I do not have battery and all the rest
beyond what the pump says, how much do engines ask you?? ?
Anyway, if you don't have electricity on board... nothing proportional
Maybe you might be okay with this.

from some calculations made I need 150 nm motor and from the engine board I saw to make the turns that serve me and the couple that serves me, with 10 l/m and 80 bar motor I have a pair of 204 nm so I think it goes well10 l/min is enough for your two engines? Did you do the calculations?

So I'm moving? Shall we?
and above all... steering?? ? ?
