Are you looking at trying to transition two
shafts, or are you going to actually use this
as a steering box?
The shafts turn in the same direction, though
I'm not familiar with the internals.
Vega steering boxes have a 22:1 ratio.
I hate Chevy's.
Fess up time.....I am trying to do something that apparently no-one has else has tried to do....or at least are willing to admit to doing.
I am investigating the best and most suitable steering gear box on a vehicle to convert the steering in my A100 to power steering
The biggest problem with the A100 and other similar vehicles is they are Forward Control, and as such run a solid Beam axle. There is no K-Frame to mount anything to, which adds to the difficulty. I thought I had a winner with a Toyota 4WD steering box, but they traverse across the front end, and when they return, the rotation is opposite to what I need.
The Vega box pictured above in Post #1 is about as small as they get, and looks to be the easiest retro fit of any box I have seen.
Trust me, my friends have been looking for me, and I have been searching nearly 5 years on this project. Even the local experts on Steering here in NZ are not able (or willing) to offer a solution.
Now that I have recently discovered that the Vega box is being produced as a powered option, I am salivating again at the prospect. But I need that rotation to be correct.
The steering gear box in the A100 is very much like the Volkswagen Kombi steering box....and is commonly known as a "Bus Box".
Nearly every box I have found has the output shaft on the wrong side to what I need, and even allowing for rotating the mounting position, it works out to either consume too much space, or provide headaches for attachment to the chassis.
That's a basic view of underneath these machines. The steering box output moves a drag link to the arm attached to the driver's side backing plate assembly. From there the main rod traverses to the passenger side and operates that arm via the only tie rod end on the front end. It's very agricultural, but works.
When the input shaft is going clockwise (3), I need the output shaft going anti-clockwise (1) - turning right in the vehicle.
and visa-versa...
When the input shaft is going anti-clockwise (4), the output shaft should be turning clockwise (2) - turning left in the vehicle.
This sort of question is something that the supplier (Summit) will not answer for me.
