1.where : Australia
2.when : October
3.budget : Don't care
4.total load : 190 Kg
5 wheelbase / wheeltrack : 1700/1000 (mm)

We must consider weight and accuracy
( plz choose rack pinion steering or kart steering)

1. Cost
2. Weight
3. Effectiveness; R&P steering requires many turns of the steering wheel to achieve what direct steering achieves in half a turn of the steering wheel...

Affected by hand tremors is more large kart steering than R&P steering. isn't it?

I also have to consider about Energy efficient ( beacause of we make solarcar ) (Unnecessary Movement of the wheel causes energy loss

#Thank you Fabroman

simple: you don't!

but if you really need to fix a complete awkward steering ratio,
you'll elongate or shorten the pitman arm to increase or decrease the wheel angle per steering wheel angle.

Or if you have a rack and pinion system you swap that to one with a different ratio
( or if possible swap the pinion to change that)

if you need more details, please take a pic of your steering setup;
make sure we see as much as possible.
(from the linkage on the spindles , over the tie rods to the pitman arm)
sometimes the spindles have too long/short linkages or just the wrong ones for your application;
sometimes your steering feels "ineffective" not because of it'S ratio but because you geometry is far off etc.

So the more we know/see the more we can help.

Depends on your definition.

Modulate: to change or adjust (something) so that it exists in a balanced or proper amount OR to pass gradually from one state to another.

From the loss of energy perspective, you may be better off with R&P. Your kart style steering is going to be more sensitive to input from the steering wheel, and you would definitely want to make sure to use very high quality components if you go kart style to make sure there is absolutely no slack in the joints.

Brother, has anyone tried a hydraulic steering for a gokart??? Talking about advantages, we can adjust steering ratio over a regular fluid control valve right??
Please correct me if Im wrong, it was a idea of mine.

Another dumb idea, do you have a relative in Texas named Free Runner? Why would you want to put a power sucking hydraulic pump on a small engine? You would have no power to move the kart then MR. Engineer.

weight of gear

:2guns:
To Brothers....
Do you know the weight of the rack and pinion gear? In Approximately

I want to know weight difference between R&P and Kart steering

Sure, it's difference is about this big:

No really.. can you please be even LESS exact with asking questions?
have you seen rack and pinion setups ?

I've seen pinions as small to fit on the tip of your thumb
and big enough to barely fit the palm of your hand.

FORGET rack and pinion! (really.. forget about it...)
you want to have it as light as possible: use the fewest parts possible, then reduce their weight

ANd really.. I understnad your intention, but keep all your solarcar related questions to ONE thread maybe,
that way it's much easier to get the context of your questions.

[and with that I'll merge a few]
