JJ, that steering is confusing to me...are the rams not fighting one another??? A single ended ram travels faster one way than the other...correct? With them facing opposite directions, there is bind...???
Or has this been totally discussed in your build thread and I just missed that part... :dustin:
Dallas just brought up that you may be connecting the two rams by a jumper hose...
Wait, if this has been covered, just tell me so and I'll search for it.
It doesn't fight itself, but I dont know that I can expain why. But I'll try.
1) The two ports of each cylinder that correspond to their respective right and elft turn actions are tied together by a t. This means that they receive the same supply of fluid.
2) Since the cylinders counteract each other (ie to turn right, one extends, the other retracts), and the cylidners are the same size, all the fluid leaving one goes into the other in equal proportions. Basically, the two cylinders working otgether turn them into a single balanced cylinder as an entire unit. Therefore, for every CID one looses, the other gains. Since they are tied together by a tie-rod, one can't get ahead of the other.
Like someone said, lots of heavy equipment and tractors use this setup. Also, many monster trucks. I'm not sure why. I just did it because I changed my front ram from the single ag unit to a double-ended unit and had the extra ram left over. By moving it to the rear and mounting them high, I was able to get my entire rear-steer system up higher.
I don't know that I explained it clearly at all.

BUt none of this was ever covered in any of my build threads.
