The design of train wheels is genius. If we have a train track with a slight curve, and we try to roll some basic wheels across it, we'll simply derail. Okay, you might say, it's an easy fix. You could just add a flange so it doesn't derail. And while the flange does keep it from derailing, it can't really navigate a turn. So how exactly can we solve the issue of a train negotiating a turn?

There is a wear condition called hallow tread where the tread becomes inverse causing the wheel to straddle the railhead. This condition causes the wheel to hunt because it wants to go straight only.

@twobrotherskayaking4736 24 күн бұрын

7.9.3 Hollow tread A visual examination of the wheel will be necessary to determine if a hollow tread is evident. Note: Class 1 hollow tread, class 2 hollow tread, class 4 hollow tread and class 5 hollow tread classifications are not relevant. 7.9.3.1 Class 3 hollow tread The maximum permissible tread hollowing is 3 mm nominal, as determined using the wheel gauge as shown in Figure 11. Refer to Figure 20 for wheel hollow tread gauge. Action Required: Locomotives and passenger vehicles must have inspection details recorded by the operator and be scheduled for wheel turning within 14 days of detection. Freight vehicles must be worked out of service for repairs. Speed Restrictions: No speed restriction for any vehicle with a hollow tread. I have read the Engineering Standard Rolling Stock ESR 0330 WHEEL DEFECT MANUAL Version 1.2 and there are multiple ways a train wheel can become defective along with 5 classes of severity. It looks to me like this type of wheel would require a completely different track profile and one that is not currently available. Also, as this is not currently in use. Good luck getting the FRA and AAR approval! It's like pulling teeth to get a new technology online with the current outdated, antiquated railroad systems that operate our nation's railroads.

But the small contact area of the wheels and rails also affects the strength of the brakes, it also placing the center of weight right in the middle of the rail so it can damage the rails more quickly, the limited area of surface contact is also can cause serious problems just because the rail sections are not smooth, so the rails inner side require more maintenance for the train operations.

@Kris-fd9xs he kinda butchered the explanation. What he means is since the flange is on the inside of the rails if the car tips in a turn and sit on only outer wheels it stays in the rails. If we put the flange on the outside of the rail it will just slide off in the same situation. But in reality the purpose of putting the flange on the inside was mainly just that it's easier to make switches. Just think how the hell you'd make a switch otherwise.

@Ollitopay 10 ай бұрын

I meant the geometry of the wheels as a whole. The load being centered is more of a function of the taper of the wheels than the position of the flange. The reaction force of the wheels is upward and inward toward the center. If the wheels were flipped inside out, the same forces would be upward and outward. The train would always be pulled to one side of the tracks or the other instead of the reaction forces of each side pushing toward each other in the middle.

@Mr._Bellic 4 ай бұрын

Not only that, but the wheels would turn at exactly the wrong speed. The outer wheels would turn too slow and the inner wheels would turn too fast. The opposite should be true; outer wheels would rotate faster (larger surface area, same time to rotate, larger circumference/second, more linear momentum/second) and the inner wheels would rotate slower (smaller surface area, opposite explanation.)

To give some more context, we were in a day care situation with many kids who loved to talk about our travel that day while sitting in a train. That one kid however was suddenly frightened of the trains movement and thought it was super unsafe. I explained that even if the wind partly caused the shaking it is perfectly safe to use the train. It is much safer than us driving by car and so on. I think a more exact and informed explanation would have calmed her down more. It was important that she felt a little more ok with the situation since a few younger kids became anxious after she said that taking the train is unsafe, it might just derail like that. After making sure everyone knew that wouldn't happen right now, I just went on asking them about how excited they were for the trip. So their lil heads would be occupied with something else other than everyone dying.

Ever since I learned about differential steering, I've always wondered how it worked on trains. Now I know, thank you.

@willbroshears5015 11 ай бұрын

It’s similar to a differential gearbox that is used in automobiles. When wheels on an axle turn, the wheels have different RPM. The larger diameter wheel takes longer to make a full rotation than the small wheel on trains, allowing the turn. Cars accomplish this with a complex gearbox that rotates the wheels at different rates, since the wheels are the same size. Technically trains don’t have a differential, but the concept is very similar to that seen in cars.

@rougezeus2154 11 ай бұрын

Hate to be that guy but trains don't have differentials. The wheels are on a fixed axle but the shape is designed in a way it acts as a differential does. Allowing wheels to spin at different speeds. Cars on the other hand do have differentials because the wheels are the same size it just needs the same effect for turning and the differential does that

@DearLilBunBun 10 ай бұрын

Pretty sure it's NOT a differential. I get what you're saying, but cleverly designed wheels /= differential. As the other person stated, the differential is the mechanism that makes the wheels spin at different speeds to turn, trains do not do this, and don't have differentials. For anyone else reading this. Your car has a differential, and if it's a 4x4, it has two differentials. The differentials change how fast each wheel spins, so you can turn smoothly. If you turn left, the left wheels on your vehicle have to travel much less ground, than the wheels on the right, so the wheels on the right rotate FASTER than the left wheels. If your wheels rotated at the same speed while you turned, it would be hard to control, your axle would be under immense stress, and could snap, and you could skid off of the road. You'd have to slow down SIGNIFICANTLY to make any turns at all.

Train conductor from Sweden here. I know this is only about the wheel itself, but there is more to it. The bogie of a tracked vehicle is rotatable in the horizontal plane so that it can turn in the passage of curves. In addition to dividing the load on several wheels, a bogie is important for the running characteristics of the rail vehicle. The rolling paths of the wheels are conical, which makes them self-centering. If the wheel axle rolls to the left on the track, the left wheel will travel a little further than the right because the diameter increases on the left and decreases on the right. The bogie then gets a slight turn to the right and the axle steers towards the center again, etc. Under the running characteristics of rail vehicles, this is described in more detail and how passive and active radial steering in a bogie improves comfort. At the same time, this conicity causes the diameter of the outside wheel to increase and the inside diameter to decrease, which compensates for the fact that the outside rail is longer than the inside.

This is the same reason why a spherical ball follows the tracks. A balls axis of rotation can tilt dynamically relative to the radius of the track's curvature. The only reason why our train wheels are cone-segment-shaped rather than spherical is that spheres have a punctual point of contact with any flat surface and cones a linear one, we need the latter because it gives more surface area between tracks and wheels to spread the weight of the train on.

@krumbleme2 10 ай бұрын

Would there be any benefit or advantage if our cars had these cone-shaped wheels?

@qazmatron 10 ай бұрын

@@krumbleme2 A spherical rim surface should not confer an advantage. (First, a portion of the surface of a sphere with the diameter of the rim would have too much convex curvature; to have a larger second diameter, the shape must be a portion of a toroid; that allows a slightly convex or slightly concave curvature.) The difference in shape would be too small to see or easily measure. The top of the rail is crowned, not flat, so the initial contact is a point, whether the wheel surface is perfectly conical or slightly toroidal. Under load, the wheel and rail deform slightly, increasing the area of contact. The absolute optimal wheel probably is neither exactly conical nor exactly toroidal; the optimal shape probably depends on multiple factors including the profile (shape) of the rail, the length of the axle, and the length of the bogey; it can be developed by modeling the system and refined by measuring forces and movements on working railcars.
