Tube insert hinge?

[swbooking]

Im building a rear tire carrier and need to know if anyone has ever seen or know where i can get a hinge that welds in like a bung for tubing.

Ive been searching around but cant find anything like it. I need it to be able to hold atleast 100lbs, would like more like 200-300lbs if possible. and i need it to open atleast open and close atleast 80*

Let me know if you guys know of any companies who make it. Thanks.

trailer spindle is typically used for what I think your discribing.

Nope not a trailer spindle, im making mine a little differently. I need something like this tube clamp except with a hinge instead of a locking mechanism....

Do you want it to swing mid tube length or at the end of some tube?

You say you are doing something different?
In my mind the difference between a hub/bearing and a hindge is only the angular motion that it allows. Is there any reason why you wouldn't want the 360deg of motion? Keep in mind you can limit your travel in other way's.

Also, Most hindges will have more drag and not allow as much weight because they are not supported as well as a hub/bearing.

Well without really getting in to what exactly your doing, still kinda lost here. I would say it sounds like you might beable to get some DOM in the same or close ID as the OD your looking to swing on, then cut that tube section in half long direction, weld on some strip/plate pieces to each half so they could be bolted back together around the supporting tube. Then do the same with another pice and weld it directly to the support tube below the slipt/bolted piece, setting your hieght with it for the slip piece to rotate on. It would not be smooth, but it would be very functional.

Or you might be able to just find a tube clamp that is pre fabed in the right ID?

Are you talking about something like this?

That's my question too. If this hinge is supposed to go at the end of one tube where it meets another tube perpendicularly... then maybe you could make your own hinge out of a couple different sizes of round tube with plastic or brass used as a bushing. :dunno:

A-Upper Tube
B-Center Slug/Od of tube matching ID of original tube
C- Tube Clamp
D-Lower Tube
E-Delrin/HDPE Bushing


Weld washers to the top of the clamps, cut in half so they will come apart again, to retain the delrin/secure position.

EDIT: add a zerk if you want to try and grease them.

cool thanks for the tips guys...

yeah its going to swing at the end of the tube at a perpendicular junction pretty much. Ill try to draw something up to better explain myself.

JR, no its not like the rockstomper hinge, it would be a little different...

I know i can make it with a rubber bussing and a couple tabs, but i just wanted to see if anyone made exactly what i was thinking about but i guess its kinda hard to explain.

Hear is how I did mine Allen, have beat'n the hell out of it for 2 years now & no issues..

Basic design, 1.75 Solid bar drilled to 7/8, taped for a zerk fitting & 2 tabs welded to the bumper. No tail light blockage either just food for thought..

 

[swbooking]

Nice Billy, I like that. I might just go to a design like that instead...

I drew up what i need, ill see if i cant get it into solid works and post up the pic of it. If i cant ill just post up my drawing in a bit.

 

[swbooking]

Here are some drawings. I didnt have time to do it on SolidWorks so you guys get MS Paint instead.

Here is the basic concept of the tire carrier. The hinge on the bumper will be made like Billy's pretty much except with a poly busshing instead. and the "tube insert hinge" i need will be located right above the tail light connected to a perpindicular piece of tube that will tie into my exocage. (which runs right behind the rear passanger window and down to the rear bumper.)

Here is my original drawing i did on a paper, you hopefully can get the basic idea of the part that i need. (by now, ill probably just have it machined at school if i go with this design)

and heres a litte better, but still crappy, "cleaned up version" of the drawing. Lets see if you guys can understand it a little better now.

 

[RWKHausSupply]

Nice tech drawing :laugh: J/K

Well I would rethink the poly bushing. You never see that design due to the deflection that it would be under consistantly. Failure of that bushing would be fast, and the whole assembly would be rocking and a rolling from day one.

So is the rear hatch not operable now?

I believe a Heim joint threaded into a bung welded into the tube would work for what you want to do...at least in the one tube. The double shear on the other tube would have to be welded up, but pretty easily doable. I must also agree that the poly bushing is a bad idea. I would use another heim or a tapered roller bearing on the lower hinge. Jeff

 

[swbooking]

Robert, Yeah i was thinking about how much strain the poly bushing would be under considering the acting downforce on it would probably be pretty high. No the rear hatch works fine.

Jeff, Your right that would work. Theres actually a couple different ways i could go about building it, i was just wondering if the "hinge" i need was actually in production somewhere. I think it would look the cleanest.

A Hiem is not designed to take a side load, and the wieght of a tire/wheel adn the tube mixed with the forces while on say washboard or even rock crawling, would be too much I would think for anything less then a 1-1/8 hiem. Just do solid mount.

 

[swbooking]

Solid mount it is for the bottom hinge then.

Here are some drawings. I didnt have time to do it on SolidWorks so you guys get MS Paint instead.

dimensions are off a bit, 1.5" x .120" wall tubing has an id of 1.25" + or -.

I see what you are looking for though. I used a trailer spindle, single shear and all that but it seems to be holding up fine so far, not much room to work with back there with the hatch/lights and all but hellbillies design looks pretty simple and functional. good luck with the rig!

 

[swbooking]

Yeah i think Billy's design is the best option in hindsight (probably cheapest in my case too) I have a rear tire carrier we made for a YJ that i can use the basic frame of, just have to modify the mount to fit the XJ.
