From what I understand, differential gears were not created by any one person. It was independently created multiple times in multiple regions across Eurasia at multiple points in history (eg. the ancient Greeks, ancient Chinese kingdoms, etc independently developed it as early as 2000 years ago). So it was already an old and well known concept by the premodern era.

@@Intranetusa Oh wow, that's interesting

To my mind, this is more beautiful and profound than any work of art.

@@Intranetusa I guess I'm not well versed in history that far back, but, as I understand it, it was also used as a multiplier gear in mechanical adding machines before it was in cars.

Repent to Jesus Christ! “In the past God spoke to our ancestors through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom also he made the universe. The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven. So he became as much superior to the angels as the name he has inherited is superior to theirs. For to which of the angels did God ever say, “You are my Son; today I have become your Father”? Or again, “I will be his Father, and he will be my Son”? And again, when God brings his firstborn into the world, he says, “Let all God’s angels worship him.” In speaking of the angels he says, “He makes his angels spirits, and his servants flames of fire.” But about the Son he says, “Your throne, O God, will last for ever and ever; a scepter of justice will be the scepter of your kingdom. You have loved righteousness and hated wickedness; therefore God, your God, has set you above your companions by anointing you with the oil of joy.” He also says, “In the beginning, Lord, you laid the foundations of the earth, and the heavens are the work of your hands. They will perish, but you remain; they will all wear out like a garment. You will roll them up like a robe; like a garment they will be changed. But you remain the same, and your years will never end.” To which of the angels did God ever say, “Sit at my right hand until I make your enemies a footstool for your feet”? Are not all angels ministering spirits sent to serve those who will inherit salvation?” ‭‭Hebrews‬ ‭1:1-14‬ ‭NIV‬‬ N

@@cameronrichardson3108 I was able to keep up until he started explaining how the spider gear works. I still can't understand how one axle can turn slower than the other when both are meshed to one piece.

how old are u?

@@RichardFStripeRendezvous Maybe this one explains better: kzfaq.info/get/bejne/r79xqppqmJ6ah30.html

@@RichardFStripeRendezvous so when its going straight, both wheels want to slow down so they both exert a force backwards on the spider wheel but they cancel out. Image just the left wheel trying to slow down, it would push back on the spider wheel and rotate it counter clockwise. If the two wheels are doing this theyll try to rotate it opposite ways and it cancels out. (This is about why they dont rotate when going straight) Now for turning, the spider wheel is pushing both wheels forwards still because of the larger gear it is mounted on, but the wheel on the right needs to spin less and if it didnt it would have to slip and drag along the ground. This is friction. Instead of this friction happening to the rubber of the wheel it carries through the axle to the spider gear. Remember what we learned about both wheels equally pushing back on it? Well now this added friction causes the spider wheel to rotate. If you look at just the sides of it where it connects to the wheel axles, on the right side the larger ring gear rotation will be rotating the right wheel, but the spider wheel’s side that we are looking at is moving the opposite way. For the left side its the same, but since the friction is rotating the spider wheel on the right this rotation is added to the left axle. You really just have to think about the gears colliding and pushing.

yea u wont ever notice it but when you think about it you might have doubts

No.

TBH, they probably just threw it together and figured out how it worked after they learnt that it worked :-P

@@Dalorian1 still there's effort

@@masterplayer5982 can't appreciate them but still using their ideas and tech on your vehicles... no surprise people like you exist..

@@HELLO7657 Modern yes. I'm talking about The original industrial revolution, we are currently in the third industrial revolution where in everything is in depth and calculated.. Originally it wasn't this way :-D

There's a rear end called a "Detroit Locker" that locks the gears so they turn at the same speed. I don't know it's origins but's used for drag racing so power goes to both wheels evenly at all times. If the racing car turns a corner the inside wheel typically chirps as it rounds the corner because the weight is on the outer wheel and the inner wheel has to spin freely by doing short little wheel hops.

I think most inventor and or engineers simply wanted more efficient ways so they come up with rough ideas until we finally get what we have now. They're goal is to solve problems first. Then they can improve on that I suspect.

There's another one in the video: "The spider gear plays a pivotal role here."

They got big brain

if a differential is part of an integral, it would came back to its original value, plus the c i gues :))

And later, "the spider gear plays a pivotal role here"

Can you please explain to me that how and when the spider gear "Knows" which direction the vehicle is turning?

I don't think that makes it easier to understand. The unit contains only gears, and gears don't freely slip.

@@jesusislord6545 Jesus was a Prophet. Period

Why is it called a spider gear?

You are both correct. He says all the POWER goes to the right wheel. In the situation shown, torque is the same, but rpm of the right wheel is significantly higher than that of the left wheel. So both wheels receive the same torque, but the right wheel expends way more of the horsepower (torque x rpm) in doing so

power stays the same but torque doesnt. Power is based on rpm as well and since 1 half shaft is goinng faster itll have more power at higher rpm but less torque

also not sure why they call it a pinion on the drive shaft, typically pinions are the driven gear(s), and the drive gear is the bull

The force vectors on two sides of the spider gear decide the turning of spider gear. If the forces are same, the probability of rotation becomes 0. Sounds esoteric but thats how its embedded in our physics.
