Truck Axle Prognostic System

Then Google: Truck Axle Prognostic system.

Let us know what you find.

Rule 75 again...

Prognosis of what?

Imminent bearing failure?

Excess mass?

Sudden infant death syndrome?

Cardio Myopathy?

Colonic polyps?

Give us a clue, please.

Guys, thank you for the comments. Here is some more information: The system which sits on the heavy duty truck axle with necessary sensors and software, is expected to be smart enough to indicate on the driver's monitor, any abnormalities in a particular brand of axle, in comparison with an ideal one with the same specifications and brand. I hope this would help.

This sounds like a very expensive system. I could see the justification if truck axles were prone to sudden and unexpected failure.

As far as I know, heavy duty truck axles are...........well..."Heavy Duty". I can't come up with a viable reason to install an expensive, real time electronic monitoring system on an axle. Please enlighten me if I'm missing something.

Heavy commercial and mining trucks are expensive machinery, they must work 24/7 as down time for repair would cost fortunes so preventive maintenance is a must

yup, their is.Read your high school auto shop book again. if you still don't get your answer read it again,and so on. And make sure your wingnut is tight.

dude you have to give more info. sure you can check back lash,bearing ware,pinion depth,spider gears,clutch packs and the list Go,s on. is it for German,Asian,USA. a Rockwell 5 ton a 2-1/2 ton,ton and a 1/4,Dana 60,sterling 10.25,12 bolt,10 bolt,9 inch 8.8,8.5,8,7.5,slot car or what. look up an article on setting up a differential,you will get a lot of the answers you seek. good luck,love and lolly pops. O and use synthetic,trash the Dino oil.

That's worth a GA. Big difference between passenger trains and commercial trucks though..........not that this system couldn't be adapted, I just don't know how many would invest in it for trucks. I'm guessing not many. Unless of course, the OP could convince the government to make it a law.

Thanks for the reference link. I browsed it, very informative and useful. Regards, JB

Looks like a much simpler system could be implemented to monitor for vibration or overheating at wheel/hub assembly, rather than whole axle. A quick look around indicates that most failures happen here, as opposed to axle failure.

Thanks. I agree that temperature and vibration would catch most faults.

Didn't know axles were such a big failure item.

Thank you for the comment, very interesting suggestions.

If I remember correctly Lyndoor industries markets an excellent power steering tester that might be able to be modified to give the warnings you desire.

Thanks for the plug Bob. This unit is no longer available from LynDoor™ Industries. We sold that business unit some time ago. As I undertsand, there may be some residual stock in inventory with the new owners.

They can be contacted at "Big Billy Bob's Boat Anchor and Steel Supply". WWW.BBBBASS.com

I am in agreement with you. The HD ABS systems are already out there, and are assembeled by the axel manufacturers. It would not be that difficult to incorperate heat sensors and possibly vibration detectors into the mounting of the existing wheel speed sensors. And just as the ABS does not know what speed a wheel should be at unless it compares it to the other wheels, the heat-vibration sensors would need to be compared to each other to make a decision. Although there could be some predetermined temperature or vibration level above which the system would automaticly trip, causing a warning to the driver.

It seems that most of the system is already in place.

i can see a system being used in steady long haul applications. clogged vent tubes have been known to be the result of a short lived differential. usually happens to the people that like to play in the mud . I would think a good quality monitoring system that you could count on would cost more than rebuilding the diff. unless we are talking flux capacitor diffs.
