    Whoever created the differential is a genius. I didn't think that differentials were this simple and compact.

      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.

      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?”

      @@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.

    • @scottheywood6502
      @scottheywood6502 Před 2 lety +1

      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.

      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.

      @gunshipproduct2 Před 3 lety +11

      When travelling in a straight line:
      The rolling resistance of each wheel is near equal, and the spider gear will not rotate about its own axis. There is no net force that will cause the spider gear to rotate on its axis.
      When negotiating a turn:
      The rolling resistance of the inside wheel increases. The outside wheel begins to move a higher speed. The spider gear will begin to move on its own axis as the two axle shaft gears rotate at different speeds.
      The spider gears are not powered to move on their own axis. They move on their own axis only when the rolling resistance of one wheel increases vs the other wheel. Think of the spider gear as: a way to apply constant power to the wheels as they slip. Instead of the false notion that: the spider gear rotating on its own axis then causes the output axles to move at different speeds.
      If this is still insufficient or does not answer your question, watch US Auto Industry's How a differential works. Its a 7 minute commercial from General Motors corporation that explains a differential beautifully through real examples.

    I feel for those who are still not getting it that a different wording is needed. The differential allows the wheels to freely slip relative to the main drive shaft and relative to eachother. The differential has no direct control of the individual wheels apart from when both of the wheels are rotating at the same speed (equal forces)

    @JustAPersonWhoComments Před 2 lety +10

    A differential is a gear train with three shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average.
    The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears (these are not strictly necessary - see spur-gear differential):
    Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears (which drive the axle half-shafts) will rotate at different speeds relative to the ring gear (one faster, one slower) by, say, 2 full turns each (4 full turns relative to each other), resulting in the left wheel making 12 rotations, and the right wheel making 8 rotations.
    The rotation of the ring gear is always the average of the rotations of the side sun gears. This is why if the driven roadwheels are lifted clear of the ground with the engine off, and the drive shaft is held (say, leaving the transmission in gear preventing the ring gear from turning inside the differential), manually rotating one driven roadwheel causes the opposite roadwheel to rotate in the opposite direction by the same amount.
    When the vehicle is traveling in a straight line there will be no differential movement of the planetary system of gears other than the minute movements necessary to compensate for slight differences in wheel diameter, undulations in the road which make for a longer or shorter wheel path, etc.

      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?”

    Great animation! Just the one correction towards the end of the video: an open differential, by design, *always* sends equal torque to the left and right sides. There are inherent manufacturing imperfections and other issues that contribute to 'torque steer' and 'torque wander', which is why in practice any road load data will not show a perfect 50:50 split.
    When one wheel is on ice, for example, the loading on the engine drops, so the overall torque being sent through the driveshaft drops, but is still split nearly equally across the halfshafts.
    Another way to understand the torque path is through classical mechanics: the pinion gear applies a force (N) on the ring gear, which gets multiplied by the length from the center/pivot (m). This gets applied to the side gears via the spider gear. When the car is moving in a straight line, the force is equally applied in the same direction to the left and right side gears. When a wheel begins to slip, the force is still equally split left to right, but the direction changes (one sees the force in the opposite direction). This video has a great representation of that around the 3:00 minute mark. However, since the same force is being applied on both sides and at the same distance to the pivot point (but in reversed directions), the torque applied to both halfshafts is the same.

    • @dsdy1205
      @dsdy1205 Před 3 lety +2

      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
