The speed differential is seen as the greatest invention in the history of cars, and it can be said that it is not the engine, nor the gearbox, that hinders their rapid development after their birth. What does it do? How does it work? In short, the power of the speed differential is to move the wheels at different speeds. This is due to the fact that the wheel on the inner side of the vehicle turns a little slower because of the small radius. The outer wheel needs to turn faster because of the large turn radius。
If the two wheels continue to move at the same speed, there may be drift or a side flip. The problem was solved by the invention of the speed differential. It would have been an axle linking two wheels, so that the wheel on both sides would have the same speed。
• first, the axis is to be cut off from the middle, then one umbrella gear at each end. Put another gear in the middle of the two umbrella gears so that they can come together。
• then connect to the axis of the side through the axis. If the middle gear turns, it drives the gear on both axes, and the wheel turns. Then we found a gear in the middle, which was smoother。
That's how it works. It's interesting. When you turn, if the wheels on either side are blocked, they won't be affected by each other, which means you turn yours and me. In fact, this step has achieved a different rate of turn on both sides。
The power transfer is to replace the axis with a large umbrella gear and then connect it to two gears in the middle, which is basically the complete structure of the differential。
• a slightly smaller gear is used to bind the large gear, which is used to drive the large umbrella gear, which also solves the power transmission problem。
Both sides travel at the same speed, with different grips on both sides of the wheel, with small resistance in the outer circle and slow in the inner circle, so that each turns without prejudice. Here's a visual look at this model, and you see it all the same on both sides, and if you hold the wheel on one side, the other side doesn't care how it turns。
Speaking of which, we have learned before that the effect of the speed differential is to make the wheels turn at different speeds on either side, so that when the car falls into a pit or crosses the field, the wheel turns fast and does not go anywhere, so it will not pass。
The difference lock is to push through the internal structure, like a plug-in, and fix all the gears inside, and, of course, there are many ways of locking them up, so that both sides are a whole, the wheel turns at the same speed, and it's more appropriate to cross the pit with force。
Finally, to sum up, the effect of the speed differential is to make the wheel turn at a different speed on both sides, so that the turn is more stable. The differential lock is to lock the differential, render it useless and turn the wheel on both sides again。
