Talk:Torsen

Proper name
Torsen is actually a Quaife trademark, shouldn't the more generic term "Torque Biasing Differential" (TBD) be used? --BMF81 09:39, 27 March 2006 (UTC)
 * I challenge you to find someone on the street who refers to it by the name you propose. &mdash;Joseph/N328KF (Talk) 12:20, 27 March 2006 (UTC)


 * Torsen is a trademark of JTEKT Torsen North America Inc., not Quaife. Secondarily, the article is actually about the specific Torsen differentials originally created by the Gleason corporation. If you'd like to create an article more generally about Torque bias diffs, feel free.

I believe there are other options than the RaceMaster. For example the Wavetrac is an alternative to the Quaife for some applications. — Preceding unsigned comment added by 170.148.198.157 (talk) 15:38, 10 February 2012 (UTC)

Missing Models
Models which use Torsen include certain VW passats, touareg, Phaeton ... most vw models with 4motion and longitudinal placed motors.
 * Does it actually make a difference to the internal workings of the differential (as opposed to whatever gears and shafts bring torque to the differential) whether the engine is longitudinal or transverse?Andy Christ (talk) 22:30, 16 April 2008 (UTC)
 * No, it just happens that Audi uses Haldex in the transverse engine cars and Torsen in the longitudinal ones. I don't know if it was due to cost or packaging constraints of the Torsen, or possibly the Torsen platforms were designed by Audi & the Haldex platforms by its VW parent.204.95.48.184 (talk) 22:56, 4 January 2009 (UTC)

Torsen behavior during wheel lift
There is something confusing (contradictory) about the description of the Torsen when the inner wheel leaves the ground:

"... the slower-moving wheel always receives more torque than the faster-moving wheel. [...] If one wheel were raised in the air, the regular Torsen units would act like an open differential,"

If that is true then when the airborne wheel starts spinning faster than the wheel on the ground according to the first statement more torque will go to the wheel on the ground. This is the opposite conclusion to that in the text:

"... and no torque would be transferred to the other wheel" (the "other wheel" being the wheel on the ground).

Explain the statement that "the slower moving wheel *always* receives more torque" and why this can be true even when the Torsen acts as an open differential. Maybe the problem is the use of the word "always" instead of a description of the conditions under which the slower moving wheel gets more torque. —Preceding unsigned comment added by 71.146.21.163 (talk) 05:24, 10 December 2010 (UTC)

Applications
I believe the reference to Mazdaspeed3 as an application of this particular limited-slip design should be removed from the list. The Mazdaspeed3 article itself mentions a completely different type (clutch/cone based) and this is confirmed in various other articles such as the following Sport Compact Car - 2007 Mazdaspeed 3 — Preceding unsigned comment added by 76.11.114.4 (talk) 01:31, 12 October 2011 (UTC)

It seems that the new Chevrolet Camaro is also equipped with a Torsen differential. Referring to this: Camaro Z28 Returns in 2014: Shocking Debut in NYC "Power is distributed to the rear wheels via a limited-slip differential, which features a helical gear set rather than traditional clutch packs that continuously adjusts torque bias allowing drivers to confidently lay down more power to get through corners faster." ––Nikolas Ojala (talk) 21:51, 10 July 2014 (UTC)
