Steer Clear Steering System

I was reading an article on this puppy.........

When I came across this note "This Steer Clear transfer box avoids having to use a bunch of U-joints in the steering shaft."

So I went looking to see what this Steer Clear thing is.......

First they look like this





Second this is where you may want to use one

Here is a bit about them:

Q.    What's Inside Steer Clear? How Is It Made?

A.      Steer Clear is made using 3/4" 36 splined input & output shafts. Each shaft is machine welded to a
21- tooth laser cut steel sprocket. Each shaft has two radial ball bearings on it which are held with metal
retaining rings. We use R12-2RS bearings - single row radial conrad-type steel bearings w/double seals.
These bearings are pre-lubricated and never require additional lubrication.

Next we use a #35 ANSI approved single strand, continuous (no master link), preloaded, riveted steel roller
chain. Preloading aligns the various chain components which helps to eliminate initial elongation and increase
the usable service life of the chain. The chain we use has an average tensile strength of 2,134 lbf.

There are four preset chain tensioning guides cut from a sheet of 1" thick Ultra High Molecular Weight
(UHMW) Polyethylene. UHMW is a linear high density polyethylene averaging 3.1 - 6 million molecular weight
which has high abrasion resistance as well as high impact strength. UHMW is also chemical resistant and has a
low coefficient of friction which makes it highly effective in a variety of applications, including it's use in Steer
Clear. UHMW is 6 times more abrasion resistant than steel and virtually unbreakable.

UHMW Characteristics:
       The highest abrasion resistance of any thermoplastic polymer
       Easily machined / fabricated and requires no maintenance
       An excellent sliding material due to low coefficient of friction
       Self-lubricating (non-caking and sticking)
       Outstanding impact strength even at very low temperatures
       No cold embrittlement, works from -155F to + 200F.      
       Absorbs no water and is impervious to most chemicals
       Doesn't chip, peel, crack or rot.
       Non conductive, nonmagnetic, and non-fibrous.
       FDA and USDA approved

For Steer Clear's housing we had a custom die made which was then used to make our extruded tube. The
housing is 6060 T5 mill finish aluminum that is cut, formed, welded, and machined to our specifications. The
two bearing caps are C & C machined from 6061 T6 aluminum.


Q.    What About Backlash In The Chain? How Much Is There?

A.       We only allow a maximum of  1  1/2 degrees backlash which is not very much at all. We set the tensioning
guides during assembly which allows us to carefully control the amount of backlash, and every unit is checked
before being shipped.  Then it goes on and on how they test them.......

My only comment, that chain and the gears/sprokets better be damm good.  Apart from that, a neat idea.

bonnevista:
A reasonably new application for a pretty old technology.  RHD converters in Australia have used that idea for yonks, except they used it horizontally instead of vertically.

Going back even further than that, think back to the 'old days', when formula 1 cars (and other race cars) had the engine in the front, but were still very low to the ground.  If you drew a straight line from the rear of the engine to the diff, you'd see that the tailshaft would go through the driver's tummy.  Drivers found this a little distracting, so at the diff they had a thing called a 'drop box'.  It didn't use a chain but gears to lower the mounting point of the tailshaft to the diff, but leave the diff in it's original location    

69DirtyRat:
you probably wouldnt get road feel, which takes out some of the fun, but not a bad idea!

LeighP:
Try getting it registered in NSW......

roadhound:
Very Nice Ride
