Under load, the gears cannot rotate freely. This means the wheel with grip will not receive any torque and the LSD acts as an open differential. Please note here that, in this condition the worm wheels do not spin on its own axis. In simple terms a differential transmits the power generated from an automobile engine to the wheels while at the same time allowing the wheels to spin at different speeds. While the other technologies allow the drive wheel to slip for a limited amount of time before it gets locked, in Torsen the locking action is instantaneous. There are two types of differentials available--an open and a limited slip. The Torsen differential is suitable for rear, center, and all-wheel drive applications. This worm gear is connected via the spur gears with the worm gear of the other axle and makes it turn in the opposite direction, therefore making it possible to have both wheels spin at a different speed in corners. This fact is clear from the Fig.6. To know more about the author check this link. It allows for a ratio of torque split between the drive wheels, and it allows for differing speeds of the drive shafts, much like a typical LSD. In a Torsen differential with a 4:1 bias ratio, the other wheel will receive 200 Nm or torque. Ford’s limited-slip differential is called traction-loc (though the spelling has changed over the years). The Torsen differential has many patented components and, is the most unique and ingenious method of providing differential action while overcoming the traction difference problem. Following are the some disadvantages of the Toresn type (T1) explained here. Each type of differential has its own pros and cons, including the lockers causing premature tire and drivetrain wear, LSDs wearing out, and TVDs being unpredictable. So both the drive wheels will rotate at the same speed. Pros. In this blog, we would like to explain how a Torsen limited slip differential works and how it differs from a plated LSD, like the Drexler LSD. A Torsen works on the simple principle of worm gear- worm wheel; that is a spinning worm gear can rotate the wheel, but the rotating wheel cannot spin the worm gear. C368/88 © IMechE. Please note that the wheel with grip receives 4 times the grip the other wheel can transfer to the road. At the heart of the system lies a specially shaped gear pair assembly. This means the wheel with more grip can receive 4 times the torque of the other wheel (so 80% vs 20%). The last thing we need to talk about is the differential, also known as the rear-end. The Torsen works the same as an open differential when the torque applied to both wheels is equal. In simple terms a differential transmits the power generated from an automobile engine to the wheels while at the same time allowing the wheels to spin at different speeds. As can be seen, one gear is a spur gear, and the other one is a worm gear. Then send it to yourself, or a friend, with a link to retrieve it at any time. a Torsen style differential will result in a smaller radius and a cleaner drift due to its consistent power to the rears, and the ability to send up to 75% of that power there. In our previous blog, we explained the working principles of the plated limited slip differential. When locked, it provides 100 percent of the torque to both wheels. While the TBD's torque splitting capability is fairly limited --typically about 80/20 to the clutch-type's hypothetical 50/50 -- its inherent progressiveness often pays dividends on the road course and in the real world. It can also be used in front wheel drive applications where some torque bias ratio is desirable. The inside wheel turns slower by the exact amount the other wheel turns faster. If you are familiar with the other common technologies used to overcome the traction difference problem, you might have noticed a great advantage of the Torsen. Sabin is passionate about understanding the physics behind complex technologies and explaining them in simple words. This friction is created by design and is why the differential works as an LSD. This article is written by Sabin Mathew, an IIT Delhi postgraduate in mechanical engineering. While an open differential would still power any wheels that are losing traction, a limited slip differential (aka: limited slip diff) would provide additional torque to the wheel that has traction and reduce the torque of the wheel that is slipping.
