It would be interesting having a clutch mechanism to separate the power output and isolated from the engine.

He can simply turn off the power being that this is run by an electric motor, the clutch simply disconnects the motor from the transmission.

That's pretty cool. This would be representative of a very compact transmission like might be found in a motorcycle or early FWD car. A typical rear drive manual transmission has the input and output shafts on the same axis, with the power being sent down to a countershaft to select the ratios. The lowest reduction is usually at the rear of the case, as it puts a huge load on the shafts trying to push apart rather than rotate. You'll have first, second, third, and sometimes fourth as reduction gears, with the next gear being a direct connection between the input and output shafts. After this, you have overdrive gears, where the output spins faster than the input. This is usually in a second section of the transmission, behind an intermediate bearing plate as now pushing forces are getting higher again.

That actually sound like a typical FWD gearbox, except for the 3 shaft design) - 4th gear is closest to the differential, moving away towards 1st, then behind a bearing plate is 5th and 6th (sometimes with additional bearing plate at the end of the shafts)

My favorite printed gearbox is the sequential 7 speed w reverse. Don't remember the designer but he did an excellent job. Its a good design as you can scale it with realitive ease depending on your application. When printed with nylon it is strong enough to stick into an rc car. All I have tried so far is an electric motor however I think it can handle nitro as long as it isnt too small.

Even in weaker plastics, gearboxes like these can be surprisingly durable. Someone tested printed worm drive gears with and without grease and as long as they had grease, they could 8,000 rpm for a while with no visible wear. The actual numbers might have been higher but I haven't seen it in a while

Amazing! If I had to suggest an improvement, the color coding could be improved. Everything perpetually connected to the driveshaft should stay blue, but everything connected to the output shaft should be red, so we can see better what's connected to what. The rings could be their own color like purple or something

Curious how many people watching this have ever actually driven a car with a *true* manual transmission, one with no computer involvement whatsoever. I learned on a '74 Toyota Corolla, with manual *everything*. Its clutch was incredibly unforgiving. If you were off in your timing by just a little tiny bit, the whole jalopy would start to seize, jerking the car forward and backward violently until the engine died. I have to say that learning on that beast made every other car, stick or not, I drove after that an utterly trivial undertaking!

Almost all cars (and every single van/truck) outside of North America have manual transmission. EVs are gearless. I think that the reason that the American drivers prefer automatic transmissions is ultimately due to cheaper energy costs in the US. All the best.

The red parts that slide are called a sleeves (there are 2) and the blue parts they engage with are called dog teeth (each gear has its own set of dog teeth). A synchro ring is attached to the front of the dog teeth, it can spin but if pushed towards the dog teeth it will grip. So when the sleeve is pushed, it initially hits the synchro ring and engages with it, at the same time the synchro ring grips and in turn spins the output shaft faster or slower to match the required speed. Once the speeds are matched (synchronised) then the sleeve can slide fully onto the dog teeth.

If you closely at the output gear, it is connected to the middle gear, I suppose that by moving the red bit, he is making it so that the gears get linked, by making the red bit touch two gears.

@Garanimal
@Garanimal 2 жыл бұрын
I agree, I see a lot of people saying this is a great explanation, I find it very lacking. What is happening which I think he really missed an opportunity to explain is that UNDER the red membranes are the portions of each shaft that are directly connected to their counterparts. I.E the first red membrane sits ontop of a gear that is directly connected to the motor and the second red membrane sits over a gear that is directly connected to the output shaft. By shifting the membranes it connects these gears which drive the shafts and causes the rotation. So when the membranes are in the middle they are in neutral because none of the pieces are connected. When he shifts into first, the red membrane that moves is connecting the output shaft gear (which you cant see because the red membrane covers it) with the spinning gear. If you look closely as the red membrane moves you can see the gear it is sitting ontop of. That is the critical gear which drives the output shaft.

This direct connection between the wheels (via the output shaft) and the engine is why you can start a car with a manual transmission by pushing it (or as it starts to roll down a hill) and then popping the clutch (esp. in 1st or Rev) and then quickly pushing the clutch back in before it stalls again. I used to do this just for the heck of it in my driveway because it wasn't completely flat - I'd pop the clutch in reverse... never wore out my clutch either.

That IS how a manual transmission works. Some will just have more gears but the concept is the same, more gears and red connectors will mean a bigger range of control, like 5 or 7 speed. Add a clutch and you can switch gears faster. The clutch also allows you to have the engine running while the car is not moving.

As yet i have not seen a good explanation of how it works. it's especially difficult to people to understand how locking of the gears works and thus "connect output shaft to this gear" does not help them to understand. Also mostly it is not explained, that there are multi levels on running the gears on the rod (one that drive loosely and one that is attached to rod). This is the most frequent part I have to explain using some other means. It's easy to understand that smaller gear vs bigger gear gives speed increase and driving gear one way makes the other go the other way and thus if you need to change direction you need to add another since this is replicatable easily with cups n glasses etc.

The clutch is between the motor and the input shaft (but it could just as easily be between the output shaft and the wheels). It is needed because otherwise you'd have to match the input and output speeds before those red rings would be able to interlock with those blue splines. (It's also needed to drive away from a standstill because engines can't go below a minimal rpm). Well, technically you can switch gears without a clutch if you know what you're doing but that will wear out the transmission a lot faster. And the clutch is still needed to go from a standstill anyways.

Correction: there is a speed reduction when you have a small gear and a large gear, yes, but it only happens when power is going FROM the small gear TO the large gear. In other words, if you had a small gear and a large gear like this, except it was the large gear that was connected to the input shaft (the car engine) and it was the small gear that was connected to the output shaft (the car wheels), then it would actually spin incredibly fast.
