In that original quattro system, later found in road-going passenger cars, the engine and transmission are situated in a longitudinal position. Torque is sent through the transmission to a mechanical centre differential [3] (commonly abbreviated to "diff") which apportions (distributes) the torque between front and rear driven axles. 4WD was permanently active.
Torsen differential from an Audi quattro. Torsen Torque-Sensing (full name Torsen traction) is a type of limited-slip differential used in automobiles. It was invented by American Vernon Gleasman [1] and manufactured by the Gleason Corporation. Torsen is a portmanteau of Torque-Sensing.
Audi Quattro Torsen Differential. Geared, torque-sensitive mechanical limited-slip differentials use worm gears and spur gears to distribute and differentiate input power between two drive wheels or front and back axles. This is a completely separate design from the most common beveled spider gear designs seen in most automotive applications.
Differential operation while driving in a straight line: Input torque is applied to the ring gear (purple), which rotates the carrier (purple) at the same speed. When the resistance from both wheels is the same, the planet gear (green) doesn't rotate on its axis (although the gear and its pin are orbiting due to being attached to the carrier).
A torque vectoring differential requires an electronic monitoring system in addition to standard mechanical components. This electronic system tells the differential when and how to vary the torque. Due to the number of wheels that receive power, a front or rear wheel drive differential is less complex than an all-wheel drive differential.
SH-AWD differs in function from other popular all-wheel drive systems, like Audi’s popular Quattro. For example, when it comes to torque distribution, SH-AWD is front-biased (with the exception of the performance oriented UB5 TLX Type S) but Audi's Quattro is rear-biased. [30]
Another focus of the B7 RS 4 was on the introduction of the latest development of Audi's quattro permanent four-wheel drive system. [7] [8] This utilized the 'third generation' asymmetric/dynamic [8] Torsen [7] [8] 'automatic torque biasing' centre differential, featuring a 'default' 40:60 front-to-rear torque split under normal conditions ...
Output is transmitted via Audi's quattro generation IV all-wheel drive system, initially using the Torsen T-1 50:50 dynamic centre differential, and from 2007 for the 2008 model year, utilising the Torsen T-3 asymmetric dynamic centre differential, with a "default" torque distribution of 40 percent to the front axle and 60 percent to the rear ...
