I remember that I wanted to torque it to spec and wasnt comfortable, since the torque was still not reached, but it felt a bit soft, so I stopped. The thread on my U bolts is very fine, with low pitch. presumably thats the reason for the high clamping force with less torque.
Hey guys,
I disasembled my 8 3/4" (741) rear axle and noticed that I must have obertightened the U bolts. They dug into the axle about 1/8". Can it be that the axle is distorted now?
I diasassembled it because at first drive after resto, the rear end was extremely loud and leaking. I think it...
Yeah, i noticed the original buckles are form fitting. No chance to release them with tension without destroying them. And it would take unbelievable force to achieve that.
They have just 0421 stamped on the inside of the buckle. So, "FMVSS" should be stamped in too, right?
This is very...
you are right, I will do the same. Im just a guy wants to know how things work and why they fail if they do. obviously there are a lot of people who just believe what they are told and ignore the most obvious.
Your picture shows that your buckle is the same design as mine. It will release under enough tension. Its not about deburring or buffing. Its by design. If my drawing doesnt make that clear, nothing will. But its your choice.
If your buckles hold only under laboratory conditions, they suck. And dude, i pull them apart with my hands! And you need a force measurement now?? :D :D
Just design the buckle form fitting like the original ones are. There is no need to release for a seatbelt buckle under any circumstances...
Ok, I will do other tests at the weekend. What do you mean with direct pull on the latch? As i understand, you want the buckle to remain stationary when i pull the belt, right?
But as already mentioned, the buckle has to release under some amount of tension because its designed like that. Its...
I cant tell 100% from this perspective, but Im pretty sure its the same design as mine. You have to pull really hard. Try it with a jerk. If you pm me your email adress, i can send you the video how i pull them apart.
The reason why they release under tension is the design of the buckle. Please take a closer look at my second picture. I marked the spot on the buckle, that engages with the anchor, with a red circle. It is a ramp that is spring loaded. If you pull anchor and buckle apart, the pressure on this...
Thank you for your answer. Im in car development myself and I honestly thought "if I only knew a guy who was involved in testing seatbelts, because maybe there is a situation where the buckle should open". But yeah, I cant think of any such situation.
Im no native english speaker. I didnt really get your point.
Are you working for seatbelt solutions and were watching tests at TRW? What did you mean with get paid vs sued?
