GPL diff clutches & real life

This is kind of neat. Here's a tutorial with pictures of modifiying the number of clutches on a real differential. Good thing all we have to do is click a button in GPL :0) http://www.modernspeed.net/id79.htm Hmm... It's gotta be tough to adjust those ramp angles ;-) Todd Wasson --- Performance Simulations Drag Racing and Top Speed Prediction Software http://PerformanceSimulations.Com My little car sim screenshots: http://performancesimulations.com/scnshot4.htm

Interesting article, but I don't think it's quite the same thing. I don't see any ramps in that picture which would actuate the clutches, it appears to depend on the preload springs and perhaps the thrust loading of the spider gears. Unless maybe the author just didn't show those parts in the pics. Anyway here is a site which has pics of a diff which I think is more similar to what's being simulated in GPL: http://icpcitation.com/variloc_theory.htm As you can see, this diff has sleeves with ramps that actuate the clutches when torque is applied. The sleeves can be changed to get different ramp angles. "J. Todd Wasson" <[email hidden]> wrote in message news:[email hidden]... > This is kind of neat.

<rant> Stupid site, won't work with Netscape 4.7... </rant> Just in case anyone is wondering, this "Traction-Lok" isn't a Salisbury diff, the gear pressure angles and the preload spring control the force on the clutch. The Dana "Trac Loc" also works like this (but has a different spring). Clutches are under the same force for drive and coast (assuming equal input torques). The "Salisbury" design does have ramp angles, you change the ramps by machining, or by putting in different parts that are pre-machined. The Salisbury (as you know) can be set to act differently on drive and coast.

Working with Mozilla 0.9.9 as well. :-) Too much Spyware in 6.2. -- Fester "Beware the leader who bangs the drums of war in order to whip the citizenry into a patriotic fervor, for patriotism is indeed a double-edged sword. It both emboldens the blood, just as it narrows the mind.

dave henrie Beware the leader who is more concerned about fiddling about than minding the store. For some being a leader is merely finding ways to insure you are a leader tomorrow and the next day. Such leaders ignore the needs of the country to satisfy the needs of the self. While Rome was burning with Barbarians at the Gate, the leader was too pre-occupied to defend his people.. I know this to be true because I am William Jefferso....errr.....NERO yeah that's it...N-E-R-O! <wink!> >

Looks almost exactly like the diff whose internals are currently serving as paperweights on my desk at work ;-), except that the sleeves have external lugs cast in instead of the pins and grooves on the one illustrated. Jonny

This is an excellent website...but it's still beyond my ability to understand it 100%. I'm getting closer though. Tore "Haqsau" <[email hidden]> wrote in message news:a6m4ta$fm0ue$[email hidden]...
