Yet, it still can differentiate freely and smoothly at low torque levels, so the car is docile and easy to drive and maneuver. While it is ideal for street use, autocrossing, and road racing, the Torsen differential is not recommended for drag strip use. The differential’s ability to bias more torque to the tire with better traction is characterized as the Torque Bias Ratio or “TBR” for short. The internal components application/pdf The higher the TBR setting, the more aggressive the traction performance is.The friction itself comes from our unique helical gearing. The owner's manual for the Hummer proposes a novel solution to the problem of one wheel coming off the ground: Apply the brakes. Plus I ordered new differential side bearings and races from Mazda. So, I guess I wait and see how 2012 owners rave about their new Torsen Differential and then try to go out and compare them back to back before I step up to the plate and install … Differentials Passenger Car Differential Application Guide EATON PERFORMANCE PRODUCTS 7 Drag Racing Vehicles that run on the quarter mile have unique demands. Patented Invex™, Equvex™ and Equvex II gearing give Torsen® the ability to deliver torque as needed to whichever tires can best use it, improving traction, stability, and vehicle dynamics. Torsen toque biasing differentials use cross-axis helical gears that limit the difference in speed between the two axles. The Type C is available as single or twin version; the Torsen twin C differential has front and centre differential in the same unit. The Honda S2000 comes equipped with a Torsen Type B differential. When input torque is applied to a helical gear, it creates a series of thrust forces that push that gearing into the differential casing. endstream endobj 15 0 obj <>stream Installed Torsen Diff if pictured below: Once new diff is emplaced, remove Differential Thrust Plate by unscrewing Thrust Plate screw. Use of these names, logos, and brands does not imply endorsement. The Torsen front differential’s 'bias ratio’ (the measure of how much torque it distributes to the opposing wheel), chosen during the Raptor’s development is 2.5:1 under power and 2.1:1 while coasting. Torsen differential eliminates chattering and pulling on steering wheel common to clutch pack LSD's & lockers Torsen Type design relies on worm gears that don't wear out like clutch packs CA Residents: Cancer and Reproductive Harm WARNING www.p65warnings.ca.gov . Torsens feature a clever arrangement of gears that react mechanically to the constantly changing torque forces from the engine driveshaft and axles.

Trac-Loc Limited Slip. Ford Performance doesn’t back the differential with a warranty. As the torque load increases, so do the forces, and so friction increases in proportion to the amount of torque applied. You need simple hand tools to complete installation. By tuning and managing that friction level across the performance range, the differential has the ability to support imbalances in traction, allowing the tire with better traction to receive more torque while preventing unwanted wheel spin. From the military AM General HMMWV to Audi Quattro sedans and SUVs, Torsen differentials provide the traction and handling that you need. When input torque is applied to a helical gear, it creates a series of thrust forces that push that gearing into the differential casing. This essentially represents the ratio of high traction to low traction that the differential can allow while remaining locked. The Quaife differential powers both drive wheels under nearly all conditions, instead of just one. Much of this information is applicable to differentials in general, but most is specific to the installation of the Zexel-Torsen limited slip carrier into GM 7.5” or 7.625” rear differentials with 3.23 or numerically higher gears and 28 spline axles.
