Locking diffs and locking hubs for off road use, man what good times!! I remember jumping out of the truck to lock the hubs!

I design automotive training programs, and if it were my decision, the students would watch all your videos and we would have a few classes that are specific to the maker/model. Excellent job guys, 5/5 ⭐⭐⭐⭐⭐

reinforcing what others are saying below, differentials are fascinating, If you want to make an hour-long explanation you can depend on me watching every moment. You might want to throw in something on tracked vehicles (or maybe a separate video). You make me wish I had gone into engineering :)

I have had FWD and RWD cars fitted with Torsen differentials. In my experience you don't know they are there except for big improvements in traction. Maintenance free, light and small size fitting inside an open diff casing. Ideal.

From what ive come to understand, torsens seem like a great choice in performance applications, but in certain turning situations, it can cause a rwd car (that would usually oversteer) to understeer because of where the force is being applied

Torsen really works best on FWD and AWD cars. On FWD it helps with understeer and heavily counteracts torque steer- that feeling in FWD cars when under hard acceleration the car tries to rip the steering wheel out your hands. On AWD cars it's often used on all three differentials to send bulk of the torque to one wheel that has the most traction near instantly and without the need for complex electronics. It's a really effective, simple, relatively inexpensive and low maintanance option for LSD. It doesn't need special oil additives and doesn't ware down like the clutch based LSD. It is 100% mechanical so there are no sensors that can break like on torque vectoring differential, etc. All you need to do is change oil regularly like you would any other differential so the gears don't grind themselves to death. It isn't perfect- if one wheel has no traction (is in the air or on very slippery ice) it completely stops working, which is why TVD exist.

Thank you, I always found differentials hard to understand but you explained every compenent and its function very simply and informativley

Sure, I know that. But I meant the ratio and the reaction between front/rear. If one of front wheel slips, the torque immediately goes to rear (of course with better traction), so two wheels is rotating with ratio up to 70:30 (front left and rear right, or vice versa, left side, or right side depends on the situation)

Since I’m mainly focused on RWD sports cars, from what I understood, the torque vectoring differential is kinda the best one for those cars…

Stuck on the rear wheel locking rear axle. Old school gear head lol.

Enjoying all the way from South Africa. That very informative stuff

Thank you for a very informative video. Well done. I prefer the LockRight automatic differential locker. Its way more cost effective than any other on the market. The LockRight automatic locker locks when both wheels travels at the same speed, but unlocks itself automatically when cornering. LockRight is a simple design and an ‘install and forget’ diff-locker. I know from expert gay it works very well in an automatic transmission, I’m not that sure on how it works in a manual transmission. A more advanced design is the automatic locker from Kaiser in Brazil. I have ordered one for the rear axle of my 2022 Jimny. Will order a second one for the front in Dec. -But why a locker you may ask, as the Jimny has a electronic “locker” called AllGrip Pro. Meaning the computer in the car applies brakes on the spinning wheel transferring torque to the non-spinning wheel. The AllGrip is good but reacts too slow. Sometimes the computer needs 5 full turns of a spinning wheel before applying brakes to it. Meaning, when brakes finally are added the car has lost most, if not all, momentum. With one or two lockers installed the off-roading should be way more controlled at slower speeds.

@Hardballer1100

Жыл бұрын

I had an automatic locker in the rear axle of my Jimny. It's the best option for offroad use on a budget. But on road it didn't make me happy - especially in tight corners. For that reason I changed the automatic locker for a Quaife ATB and also put one in the front axle. Sure, it's more expensive but it's the better option for off- AND on road use. It's way easier to control the Jimny with the helical/worm gear LSD's now. With the rear diff locker the Jimny was oversteering when the locker engaged and it made the already underpowered Jimny more weak. AND: I can't say that the automatic locker is 'install and forget in a Jimny with manual transmission. It clicks in every corner when not engaged i.e. not locking and it clunks at every change from accelerate to decelerate. That clunk doesn't occur when you have automatic transmission, because the propeller shaft is under load.

I have a torque vectoring diff in my current vehicle and it's pretty rocking when taking fast turns!

I believe that Thorsen differential is better then ,,open" diff. in a cheap small car. From what I understand ,Thorsen diff. in a 4x2 traction car, do not spin a suspended in air wheel (with no point of contact with the ground) while the other wheel which is on the ground (have 100% grip on the ground), stay (and not spin at all).

@robair67

Жыл бұрын

That's true. The use of worm gear-worm wheel combination means that if one driven wheel encounters zero friction condition and "wants" to spin all the available torque away, it cannot because the worm gear can't drive the worm wheel, so the driveshaft that has traction (the one on the asphalt!) controls the rotation rate of BOTH worm gears, thus transmitting all the torque to the entire driven axle. Frankly, it's genius! Works on snow, ice, mud and round Druids Hill bend at Brands!

@@legotechnicworkshop3932 there was a jeep rubicon that had a better diff still. It had a torsen type 1 i thing which has a high trb ratio, with an air lock, so you had both. That would be the best diff to have as you get both. And by both i mean, bettet cornering traction on pavememt, decent traction off road and when shit gets badz you can activate the locker. However i dont know which company makes these diffs and i doupt they make it for any other vehicle. I also believe that the gen1 and gen2 cayenne had a similar diff but instead of an atb diff they use a clutch type torque vectoring diff, with and electronically controlled lock ring. But clutch type lsds while very effective when fresh, they worn out pretty fast and need a lot 9f expensive maintance to keep peeforming well. Especially the ones with high kock percentage. In addition they are noisy and make slow speed manuverabullity difficult. Thats why i prefer the one the rubicon. Taking all that into consideration, a wavetrack diff is still one of the best diffs for on road and offroad performance, that you can actually fit on your vehicle and have no mentance requirements. Its not noisy and doesnt affect your everyday driving. However if you dont care about improving on road handling and you just want a dedicated offroader then yes any type of true locker is the way to go. Thats the long answer that i was bored to write lol.

There are a few different kinds of manual & computer locking diffs 1) mechanical 2) electronic. 3) via an air compressor. as seen in the “2019 Jeep 5/4 ton concept”.

Neither, because the street is totally different, than the strip. So if you're trying to find what's the "best". You'd then talking in terms of what's the best in "compromise". With a spool, almost unusable on the street, and a limited slip being a comprimise for the strip. You could probably get away with using a limited slip. After having it "built-up" with stiffer springs, better clutch packs, and or at the very least, adding an extra clutch disc in. To make it tighter.

Torsen diff the best!

Nice video, but be careful about specific wording. An open diff is a constant torque device, changing wheel speed to enforce equal torque for both tires. No traction on one side means no torque will be applied to the other. A locked diff is a constant speed device, changing wheel torque to enforce equal speed. No traction on one side means all possible torque will be applied to the other. Possibility of overloading factory design is possible, but in low traction situations it's unlikely since max diverting torque is limited by traction.

Torsen diff doesn't cause a lifted wheel to spin up. The worm gear of the unloaded shaft can't drive the worm wheel into motion., so it can't revolve "backwards" about the loaded shaft's worm assembly. That's the genius of the design- the worm wheel always drives the worm gear, thanks to the mesh angle. Both worm wheels from either driveshaft are in direct mesh with each other by spur gears, so the side with torque drives both sides.
