Default Mix & Match Steering

I am thinking about my next build. I have a 40 Ford front axle that I will likely use. It uses cross-steer. I also have an early Econoline steering column with the built in gearbox. My question for the day is, has anyone seen or done a setup where they use these (or similar) with a drag link and bell-crank to marry the two? I like the look of a drag-link style steering setup, and I understand the cross-steer works better, so I would like to make this work.

I have other options, if this idea is not workable.

The thing about a '39 Ford pick-up is that that ugly grille kinda' grows on ya' after a while.

Not taking anything too seriously.

Studebaker used a setup like that on some vehicles.

Well, if Studebaker can do it, so can I. Just need to design the bell crank part. Nothing to it. Right?

Thanks, smalfoot. Hope your world is getting closer to normal.

I think it would work the same as adding the top steering arm for the front-back steering to work from.
just a different mechanism doing the same thing but in a more complicated way.
i can see though where a bellcrank would reduce bump steer but if a drag link is set up properly theoretically it shouldn' t have bump steer

The Econoline gearbox arm swings front to back. That is why I am thinking about the bell crank. It also sat in from of the axle, with the drag link going back. I imaging that will add an extra point of complication to the project. May have to point the pitman arm in a different direction. Up instead of down. Haven't played with all the pieces yet.

I was wondering about something like this myself recently, to use cowl steering with an underslung frame, quarter ellipticals, and a straight axle (mounted above the spring eyes, instead of below). I very much a learner, and got the idea that unless the axle is mounted to the springs via shackles, it would cause a lot of bumpsteer, because of the unequal lengths of the steering connecting rod & the springs. So I wondered if a person could use a 90* outfit to switch the forward & back motion to a side to side motion, with another steering rod going to a center mounted bell-crank (I hope that is the right term), to which the two tie rods would be connected. I was also wondering if this wouldn't give a closer to 100% Ackerman configuration, because in a tight turn, the two separate tie rods become shorter in their over-all length, that is, the distance between the idler arm holes gets less, where as a single tie rod obviously cannot. (The shorter over-all length turns the inside wheel at a bit tighter angle than otherwise, which seemingly gives a higher Ackerman reading.) Like I said, I'm very much a learner, so now please correct me.

Neto: How can tie-rods become shorter in length???

I can't imagine how any combination of links and pivots could increase or decrease Ackermann. The attachment points are fixed. The steering arms and/or spindles are fixed. You could increase steering ratio with a bell-crank or two, but the Ackermann geometry will remain fixed.
