GTD Posted November 23, 2006 Share Posted November 23, 2006 Differential, not drugs, please? Anyone got one for sale - they seem to be fairly rare! Am taking Phil at Road and Race's advice and not going for the Quaife one! Heading back to Blighty! Link to comment Share on other sites More sharing options...
7 wonders of the world Posted November 23, 2006 Share Posted November 23, 2006 Give Dan a call @ Tran X, he'll do you a plate version set up for a Caterham with around 15% discount. http://www.tran-x.com/DiffsHTML/Sierra.html Mine works a treat 😬 Link to comment Share on other sites More sharing options...
GTD Posted November 23, 2006 Author Share Posted November 23, 2006 Sorry to be thick - what's a plate version? Is that the alternative to the Quaife? Heading back to Blighty! Link to comment Share on other sites More sharing options...
7 wonders of the world Posted November 23, 2006 Share Posted November 23, 2006 Good question, The Quaife works on the principle of epicyclic gears and the resistance they produce in the reverse motion, the ZF and Tran X versions work in a similar way to a multiplate clutch pack with the drive shafts connected to the friction plates and the crown wheel bolted to the clutch plate (flywheel and cover in a conventional clutch arrangement) The pressure exerted on the friction disc is governed in 2 ways: firstly there is a static preload applied to the friction disc via the cover plates usually somewhere between 25-50 lbs ft, and secondly rollers and ramps are employed within the construction so that i operation the crown wheel turns rollers which act upon ramps effectively increasing the pressure on the friction disc in a 'squeezing' manor thus preventing slippage. By altering the angle of these ramps and the preload the characteristic of the LSD can be tuned to a particular application, one crit of the std ZF is that the preload is too high for a 7, hence on overrun the LSD preload resistance is too high for a lightweight car to overcmoe and this can induce understeer on turn in. I known Phil tweaks the ZF for 7 applications, the Tran X can be built to customer requiremtns in the same manor. Bit wordy but hope it helps Link to comment Share on other sites More sharing options...
