In many ways, a torsen is often referred to as a fancy open diff. A clutch based limited slip, which is the most common LSD, is capable of locking the left and right axles together. The Torsen LSD is often referred to as a "torque multiplier" because it uses the spur gears to multiply the amount of torque one wheel gets, when the other wheel starts slipping. You can see the torque multiplication effect in the video when one wheel spins faster because the other wheel is stopped. In certain conditions, the Torsen diff won't work when the spinning wheel has zero traction, because it can't multiply zero torque. Because of that, and other reasons such as driver preference, more traditional LSD setups are preferred in racing or off-road applications.

If you want to get technical, it is a limited slip. While it can't solve the zero traction problem, it does try to ensure that 100% of the power is being used between both wheels (barring things like friction in its own operation) while an open diff is always just 50/50 split regardless.

@@unprofessionalanzhelia297 except that the Torsen diff is not just a torque splitter, it's a torque multiplier. Going back to the open diff, it's commonly said that it always have a 50/50 split. What that means is that if the spinning wheel only can handle 25 ft-lbs of torque before spinning, then the stationary wheel would receive 25 ft-lbs of torque. Now take the Torsen with the same example. If the diff is rated for 3x torque bias ratio, then the stationary wheel would receive 75 ft-lb of torque if the spinning wheel can only handle 25 ft-lbs. This would be a variable 25/75 torque split, depending on the situation. This variability is a major reason why Torsens aren't always used in racing or off-road applications. In comparison, a clutch LSD would be sending up to 100% of the input torque to a single wheel if needed, or a max of a 0/100 torque split.

This is also referred to as an automatic torque biasing (ATB) differential (Or Torsen, as others have already mentioned), and are a really nice upgrade over an open diff on (fast)road applications, especially on FWD cars! However, in RWD rally/drifting setups, a traditional plate LSD simply can not be beaten in terms of controllability, since you actually want both wheels locked together in those conditions when you're right foot steering so to speak...

Torsion diff take advantage of worm gear effect. You can turn the screw to rotate a gear but turning the gear doesn't want to turn the worm.

He did mention the principal of operation, though breifly. It relies on the helical angle of the "worms" being steep enough that they can only pass motion in one direction i.e. the pinion can not drive the worm gear, but the worm gear can drive the pinion.

Great model and explanation. I've always been fascinated by any type of differential, and my 1995 NA8 Miata has this exact type of Torsen (short for TORque SENsitive) differential, which is a superb diff.

I love the attempt at cinematic camera pans at the end, just a note though. for speed matching a rotation at 3:09 it's better to place the camera so the center of the image is perpendicular to the axis of rotation and you can then handle the rotation in editing later on. Place the camera further back to account for the zoom out and the fact that the image is rectangular. as for the rest, good work!

i would have liked to see more on piece by piece how one wheel slipping creates torque to the wheel thats not. but ive spent over a grand installing one of these on my truck so my interest of further explanation might just be above my head of understanding. if that makes sense.... still a well made video.

These Torsen/helical LSDs are pretty good, but when one wheel has essentially zero grip, it gets essentially all the torque. Very noticeable off-road, or negotiating driveways with a weird gutter that allows one wheel to come off the ground. The HMMWV (humvee) has Torsens diffs; the instruction manual explains to apply brakes in slippery conditions - the brakes add artificial grip to the wheel with zero grip - which forces the differential to direct torque that way.

It works extremely well with traction control because even if you get a wheel in the air will transfer more torque than an open differential would have. So basically the torque bias effect will multiply the torque coming from Spinning Wheel win the brake grabs then it would have from the spinning wheel of an open diff. So let's say open diff with 1:1 ratio bias spins and the brake grabs and it sends 50 lb over to the gripping wheel well with this 3:1 ratio it will grab with 50 lb and send 150 over. When you press the brake pedal it's not as effective because you're also adding brake Force to the wheel with grip. That's why ABS traction control works super well with these do you know what the wheel in the air. Especially if you put it on something that has a really strong traction control even with open diffs like Land Rover Disco or Range Rover from the 90s and 2000s

Not saying I know everything but I wish I wasn't a car guy so when I watched these vids it was something new... doesn't mean it's a bad vid, great vid, thumbs up here

Torsen diffs can potentially make traction control systems work much better by multiplying the torque sent to the non slipping wheel. If setup correctly, they can provide even more traction than locked differentials in certaim scenarios.

For a video titled "how it works", there's absolutely no explanation of how it works. It basically boils down to "This is a limited slip differential. Cool, right?" Yeah, but how does it work? How does it help?

I finally learnt how an lsd works. Very cool.

Correct me if I'm wrong, but aren't they supposed to be worm gears, instead of helical gears? I thought the entire point of this type of differential was that no wheel is allowed to 'lose' torque, due to the worm wheel's one-way drive property. As in: one wheel is only allowed to spin slower if the other wheel is being spun faster by the turn, instead of being driven by the differential. And if that is true: holding one wheel in place actually locks the differential, since the worm wheel won't be turned by the axle. While if one wheel is being forced to spin faster (due to turn), THEN the differential starts spinning.

Yes imagine if the blue gears were made with tiny rollers like a steering rack then it would just be a very complicated diff. But similar to worm gears they lock against each other when the torque is unequal Like having rubbish gear box that keeps locking up. But if they were more aggressively pitched like worm gears then they would be locked all the time and have no differential action under normal loads. but in the mud the vehicle is still loaded a little on the wheel that wants to slip. If you had a hanging wheel (rock crawling) then it would also fail as there would be no resistance to activate locking. The solution there is to touch the brakes a little and then you would get moving again.

So neither the Torson, or the Trutrac, are actual Lockers. They need some kind of resistance from the spinning wheel to bind up the gears to make them work

The helical gear interface creates axial thrust which resists movement proportional to torque. So when the opposite wheel has no grip and can generate no torque the gears operate as an open diff. When the opposite wheel gets a little torque then the system creates resistance and forces more torque to the wheel That’s how they bias torque on a ratio which is based on the gear profile. The more torque generated through the helical gear interface the more torque the wheel with the most grip will get.

Yes and no. Electronics can be used as a crutch and often are, but mechanical parts have their properties set in steel when they're made so to speak. If you need the diff to behave differently to account for different road conditions or driving style, you'll have to build and install a new one (the relative sizes of the blue and red gears change the exact minimum torque required to initiate the locking behavior, for instance). An electronic diff can be re-mapped for track/off-road/regular use with the flip of a switch. Also lets you account for steering wheel angle and suspension state along with lateral loads and a bunch of other things. If it's an all-wheel-drive car, this includes the gearbox changing how much power is going front to back as well.
