What actualy transfers the load on our frame: bearings, the bolts or the hole?

[spookum]

So i know all AATVs have axels that pass through the frames. When loaded, does the weight transfer through the bolts that hold the flange on, or does the load transfer through the flange hole in the frame? I only ask because it seems like the hole that the bearing flange fits into seems kind of tight, but sloppy enough that i dont think any weight or load is transferred, due to the tolerance being so loose.

Please correct me if im wrong

Spookum, I would think that all of the load or force would be transfered evenly throughout the three provided that everything is torqued downed to specs. Some members reinforce there chassis to stop flex or twist because some of the load is felt there. But in doing this more of the load goes to the bearings and everything initially connected to it, and the use of triple sealed bearings and so on is used to compensate for that, etc,,. The load or power has to go somewhere, it all cant go to the wheels, or can it? Im not a professional at this matter but more like "Jack", you know of all trades,,, master of none. These are my thoughts, what do you think?

I would guess bearing flange bolts.

What little riding i've done (bought a machine then tore it down to referb) it seems like all the load was transferred to my a$$ and back..... sorry had to be said.

I second that.......lol

Now that is the cheap way out... both take a load. But, your probbably correct. I will go see if there is any play in the flange with out the bolts in it. IF there is, then since the flange isnt touching the frame, it cant transfer the load from the flange to the frame... has anyone ever sheared the bearing flange bolts???

And yes, that shock you feel in your hiney is the oppertunity to build a springer

The force should be transfered through the flange to the frame. This is when the bolts are tight, the clamping force of the bolt acts like gravity does on your tire on pavement, the contact patch causes friction fit between the two parts. If the bolts are loose they will wear out the holes quickly and shear off and fail, the way loose lugnuts will snap your studs off. Even if the frame and flange have the body sandwiched between them, with the proper clamping force they all act as one solid body to a load that is greater than the shear strength of the bolt by itself.
Hope my ramblings dont make a simple question more confusing

Not at all, I understand exactly what you are saying,,,,, and I couldn't have said it better!!
