+ Quaife vs Wavetec by Hank » Thu May 30, 2013 9:34 pm They are adjustable with different shims, just like they are in Quattro Torsen apps. This enhances deceleration, delaying the intrusion of electronic ABS systems and allowing drivers to brake later and deeper with the Quaife ATB limited slip differential than is possible with a standard ‘open’ differential unit. Rodney Quaife produced the first 5 speed gear cluster for a Triumph motorcycle. It appears that under throttle they do. Example: when the biasing is so strong the. The latest Torsen T-3 (Type C) is a planetary type differential, in that the nominal torque split is not 50:50. The engineers only have access to the engeneering prints for the product they are working on, and sometimes only the part they are working on. So, even if a wheel is airborne, torque is applied to the other side. 3. The difference between the gripper and the quaife is the gripper is a clutch type diff and the quaife is a gear type "or torsen" The Clutch type diffs work based on wheel speed, after one wheel spins x% faster then the other it starts locking up to slow down the fast wheel and speed up the slow wheel. Quaife Engineering has been in the forefront of high performance transmission technology since 1965. hmm that is very interesting, but no offense to your source, i'd like a confirmation from a second source or even torsen/quaife. For everyday driving the Torsen is fine, it's 'better' than an open center and will mimic the locked center up to front wheel spin in a straight line. To lockers vs torsen center. Re: Quaife, pros and cons. First of all we don’t like the people at that ‘other LSD company’ they’re d***. The name comes from the term Torque-Sensing, and is gear driven, unlike other types of LSD's which are viscous or clutch type. The only reason to choose a clutch type differential over a torsen (Quaife) type differential is if you frequently get a drive wheel up in the air, such as in rally racing or when bouncing over large curb sections on road courses. () The Quaife ATB (Automatic Torque Biasing) differential is a unique type of limited-slip diff that substantially improves traction for powerful vehicles using only gear mechanisms. So if I waded through the jargon well enough, what you're saying is that the Torsen is a better unit for Road courses/autocross and the Quaife is better for Drag. I think your only difference will be 2.5:1 bias v. 4.5:1 bias. SJulian10mm Well-Known Member. This is where the parking brake "trick" can help out. in the focus world, simply because there are no serious plate-type difs on the market as an option, everyone just defaults between the quaife and the torsen. The purpose is to allow for different speeds between the two wheels, while torque split is held constant at 50/50. Torque biasing does not necessarily limit slip. Is the standard LSD or torsen better for drag racing? A forum community dedicated to Ford Focus owners and enthusiasts. ok , i knida understand what an lsd is , but exactly how does it help you , on the launch , what is its exact function ? That way, the torque required to break the tire free would be greater, and hopefully greater than the torque required for the differential to operate differently than an open diff. Its technicly designed better and for more harsh driving. The Quaife almost guarantees traction during split traction events due to the amount of gears that are required to rotate in so many different axis. ford doesn't have one, and I'd definitely like to get one if I ever need to rebuild my trans in the future. Kaaz vs Torsen Differentials. The internal gearing creates thrust forces rather than relying on spring or hydro mechanisms. If one wheel were raised in the air, the regular Torsen units would act like an open differential, and no torque would be transferred to the other wheel. A Torsen differential, which is a type of helical differential, does not use clutches as a traditional LSD does. The best of both worlds seems to be the Wavetrac, manteinance free, Torsen type but with just a pair of clutches to work (a bit) also with a lifted wheel. Then based on hexial cut gears meshing with eachother and additional gears, and the fluid in the diff the friction in those gears causes a ratio of the torque to go to the wheel that is rotating slower than the other.
