I feel like the friction design is pretty flawed since designs using friction will need replacement for those parts frequently in comparison to other types of design due to the friction wearing out after certain amount of use, are there any limited slip differential designs that can bypass this issue?

Videos like these is the reason why current EVs should be best understood with respect to FWD/RWD and AWD. It's not always a good idea to just jump straight to AWD (e.g. buying M3LR), knowing the drive motor, albeit computer controlled, should not be a substitute for tried-true mechanical understanding.

Very good explanation. Limited slip or positraction diffs are good but can get you into trouble. Ask me how I know! Air or electrical locking differentials are much better and give you the option to run an open diff or a "locked" diff. There's also another way which is using the ABS to intermittently apply and release the brake at the slipping wheel and allow the diff to apply more power to the non slipping wheel. You still have an open diff but when needed the ABS system gives you that "limited slip" feature. I have the ARB Air Locker in my Nissan Frontier 4X4's rear diff. Works great!

The clutch pack operates by pure friction? Then how are the textured surfaces not ground smooth by the forces involved? Or is the spring precise enough in compressing the plates for that? If so, that is some very clever engineering. Very impressive
@jamescole68462 жыл бұрын
No they wear out. It just takes a while. There are two major classes of limited slip differential, clutch based and gear based. Clutches wear out by their very nature, friction surfaces that slide against each other. With proper friction modified lubricant it should last quite a while, but it does wear. Gear based differentials (Torsen) use gears to create the torque splitting function. There is some surface to surface sliding but it is of hardened steel. While there is a little wear it is minimal and this type will last a very long time. There are really four types. Open: and you deal with the one wheel spin every time you get stuck but very little maintenance. LSD clutch and LSD Torsen: Tries to give power to both wheels at all times but will still slip if enough force is applied. One wears out and needs to be serviced the other is more expensive upfront and the 4th is Lockers: There are 3-4 different kinds of lockers. Some Air, Some electronic actuated, some manual. Either of these have a mechanism in place to 'fuse' the spider gears thus making a solid straight axle when activated. A lot of 4x4's (real 4x4's not the All Wheel Drive cars or the trucks and suv's that pretend to be 4x4's). Lockers should only be used in snow, mud, off road etc... with front and rear lockers all 4 tires are locked to the same gear ratio and all 4 have equal force applied regardless of road condition. Using these on hard or dry surface will put extreme force on tires and drive train components when turning (especially the front wheels) and they must be manually activated and deactivated when needed. But you will never get stuck :)

One thing that was not mentioned is that when the wheel with less traction begins to spin, an outward force on the spur gears is generated due to attempting to spin the low traction wheel, this force will further lock the clutches, the spring alone won’t create enough force on its own. All bevel gears create an outward force when load is applied.

Thank you very much for the video you made, which gave me a new understanding of the principle of differentials, a problem that has troubled me for a long time. I would like to discuss the following issues with the author and fellow fans: Suppose I install motors with sufficient power on the left and right wheels respectively, so that they can mesh with the star gear and rotate in opposite directions when the differential housing and ring gear are stationary (that is, the transmission shaft does not rotate), Is this possible? If possible, does that mean assuming the differential housing and ring gear are rotating at 100RPM clockwise, when the left wheel (left side gear) is rotating at 200RPM counterclockwise, the right wheel (right side gear) Will it rotate clockwise at 300RPM? Modified (2024.2.9) After thinking about it for a long time today, I have a new understanding of this problem. Now I think that assuming that the left wheel (left side gear) rotates forward at 200RPM, when the differential housing and ring gear rotate forward at 100RPM, the right wheel (right side gear) should be at 0RPM Because when the left quadrant point of the star gear (i.e., the point of mesh with the side gear) rotates forward, the right quadrant point of the star gear (i.e., the point of mesh with the other side gear) will rotate backward, so the connecting star The speed of the differential housing and ring gear of the gear should be half of the speed difference between the left wheel (left side gear) and the right wheel (right side gear). For example, the left wheel rotates forward at 500RPM and the right wheel rotates forward at 100RPM. The differential speed The speed of the motor housing and ring gear should be 300RPM forward. Do you think my understanding is correct?

I have been thinking of a 3d printed wind fence design, where lots of small (100 - 150cm high) vertical wind turbines applies torque to a common drive shaft, that then later goes into an electric motor to generate electricity. The idea is to make it easy to 3d print at home, and reduce amount of expensive components. Since you only need etc 1 motor for lets say 10 small vertical wind turbines connected in serial. One question comes to mind is how to make each turbine apply their share of torque to the drive shaft, considering some might catch more wind and spin faster than on the other end on the fence. I need some sort of gear that turns horizontal torque into vertical torque, but not the other way around. (so busy turbines dont spin up the lazy turbines).

Fun fact the ratio of pinion to ring is 11:43, just 1 tooth short on the ring gear to make it a perfect ratio. Why? Because it's a hunting gear set, so named as the pinion hunts for it's original starting tooth engagement as it rotates. This is done on purpose to maximise wear life of the gears and is achieved by making the tooth count a prime number.

You've explained how the clutch pack allows the axles to rotate at different speeds in a turn: The mere force of the different turning speeds from the wheels causes the disks to slip past the plates (I suppose by overcoming the amount of friction at the plates created by the spring). But you haven't explained the clutch pack causes the power, when one wheel encounters ice, to transfer to the other axle. Like most lsd videos, you've simply declared at the end that it does without explaining how. How does one side's clutch plates slipping prevent power from still being transferred to that side's side gear? If the open diff allows the side gears at any and all different rates, what prevents the gripping side from stopping while the slipping side takes all the power? In other words, what you've explained is how the point of slippage moves from the tire-ice contact point to the disk-plate contact point, but you haven't shown how that changes anything on the diff/opposite axle of the slipping side's clutch pack. Why would the diff act any differently on (i.e., transfer more power to) side gear B when side A is slipping? The ice situation is opposite the turning situation force-wise-- turning (assuming traction) resists axle rotation on the inside wheel relative to the outside wheel, but ice does the opposite, allowing freer rotation to the slipping side. You've explained the operation of the clutch pack in turning (where it isn't needed anyway since an open diff does that job), but you haven't explained how the clutch pack operates in the opposite condition-- ice allowing a wheel to spin freely. In other words, the difference a clutch pack makes is allowing an axle to be free (somewhat at least) of the side gear, whereas in an open diff it never is. But in an ice situation, so what? Friction is already freed, just farther out (where tire meets road). What removes power from the slipping side's side gear?
