Reference pictures for suspension and trailers!

[cavejohnson]

For all the scratch builders and custom builders out there...

I found my truck/trailer suspension, braking, steering, and axle repair book today, and it has some great pictures of tractor and trailer suspensions including dimensions, as well as Freuhauf and Trailmobile trailer schematics of sorts with dimensions. I tried scanning them earlier today but my scanner had a fit and screwed the images up, but tomorrow I'll rescan them.

It has a whole mess of Reyco and Hendrickson suspensions with Ford/GM specific configurations as well as Neway, Peterbilt, and other various air ride suspensions. It also has some Reyco trailer suspension setups in it.

If anyone has any requests for suspensions/trailers/steering axles/lift axles/drive axle hubs, let me know and I'll make sure to scan them!

You got any thing with a air ride spread on a reefer trailer??

The new Great Dane from Moebius has that Vantraax suspension, right?

any pics of the 1947 Fruehauf trailer suspension/frame? Or pics of a walking beam suspension with leaf springs that has pretty clear details of it?

I have a technical question regarding the Hendrickson tandem suspension pictured above. The rear driveshaft appears to be a perfect 90* to the face of both axle housings (or 0* to both pinion gears), so that both axle housings appear "tipped back" a few degrees-- is that correct, or at least accurate as far as what would typically be seen with the full weight of the tractor resting on the tires?

Or should they be positioned more like the image below, with the axle housings plumb and the cardan joints accounting for the angle differences between the two pinions?:

Ive seen it both ways Casey.  I imagine trying to keep a straighter line between the axles was a selling point ploy by manufacturers. "We degree our axles to save your U joints", in reality axles are constantly changing angles even just cruising down the highway.

Great thread.
