Kuvaus

This gearbox has 815 forward gears and 815 backwards gears, giving a ratio range from 1:1 to 1:81. The largest incremental gear step is 1.25% (1:1.0125) making this a close representation of a continuously variable transmission.

How do I use it?

Select the gear number by using the number input on the microcontroller. It accepts a number from -815 to +815. If you input 0 (zero), the clutch will be disengaged. The gearbox is not automatic, it does not change gear for you -- that's up to you.

How did I create this?

I used a Python script which first builds a list of ratios that can be created from N gearboxes (up to N=5). The smallest gear ratio with N=5 is 1:1.0125.

There are a set of M ratios, which, when turned on/off in a roughly binary fashion, will produce an almost-continuous gear range from 1:1 to 1:3. I wrote an algorithm which searches for a target incremental gear ratio with minimal M.

Here is the output of my algorithm for the gearbox shown here. It uses M=8 ratios (the final ratio being duplicated), for a total cost of 24 gearboxes.

New best found with cost 24: 0 -- Ratio 1.8 -- Repeat x 1 -- Costs x 1.0 (1) 1 -- Ratio 1.3889 -- Repeat x 1 -- Costs x 2.0 (2) 2 -- Ratio 1.2 -- Repeat x 1 -- Costs x 1.0 (1) 3 -- Ratio 1.1111 -- Repeat x 1 -- Costs x 2.0 (2) 4 -- Ratio 1.0667 -- Repeat x 1 -- Costs x 4.0 (4) 5 -- Ratio 1.0368 -- Repeat x 1 -- Costs x 4.0 (4) 6 -- Ratio 1.0125 -- Repeat x 2 -- Costs x 5.0 (10)

Turning off each of these ratios in a binary fashion reveals the full range of the gearbox. It goes a bit beyond 1:3 and has duplicates, if you trim everything above 1:3 and remove the duplicates, you are left with 163 gears. Encoding the 8-bit binary gives into an integer gives a convenient way to paste all the gears into Lua.

[0, 2, 3, 4, 6, 7, 8, 10, 11, 12, 16, 14, 18, 15, 19, 20, 22, 23, 24, 32, 26, 34, 27, 28, 35, 36, 30, 38, 31, 39, 40, 42, 43, 44, 48, 46, 50, 47, 51, 52, 64, 54, 66, 55, 56, 67, 68, 58, 70, 59, 60, 71, 72, 62, 74, 63, 75, 76, 80, 78, 82, 79, 83, 84, 86, 87, 88, 96, 90, 98, 91, 92, 99, 100, 94, 102, 95, 103, 104, 128, 106, 130, 107, 108, 131, 112, 132, 110, 114, 134, 111, 115, 135, 116, 136, 118, 138, 119, 139, 120, 140, 144, 122, 142, 146, 123, 143, 124, 147, 148, 126, 150, 127, 151, 152, 160, 154, 162, 155, 156, 163, 164, 158, 166, 159, 167, 168, 170, 171, 172, 176, 174, 178, 175, 179, 180, 192, 182, 194, 183, 184, 195, 196, 186, 198, 187, 188, 199, 200, 190, 202, 191, 203, 204, 208, 206, 210, 207, 211, 212, 214, 215, 216]

For example, the 10th gear (=12) is decoded to 8 bits in Lua (00001100), which tells it to turn on the 5th and 6th ratios. The 5th ratio corresponds to 4 gearboxes that are toggled on. The 6th ratio corresponds to another 4 gearboxes.

These 163 "little gears" are simply multiplied by 4x 1:3 gear ratios ("big gears") and a reverse gearbox, giving 1630 speeds in total using 29 gearboxes.

wtf is this monstrosity

Kindmanathome 6.11.2023 klo 20.07

please make this automatic please

buder28 5.7.2023 klo 19.41

id argue with you for power lost by more gearbox
by my experience i had a boat with 3 gearbox even if it was 1:1 it was worse than removing the 1:1 gearbox in torque
i'll look at it i wish it was a 18 speed though

Illy [tekijä] 3.6.2021 klo 20.42

You don't really lose power across a gearbox. It is an oft-repeated myth. If anything you probably gain power, which I think is because of the non-conservative torque model in the game.

Having power loss on every single gear, this thing must be incredibly inefficient. Very likely having more loss on the gears than the loss you would have by accelerating a vehicle using wrong gears.

Captain blaue Wolke 2.6.2021 klo 10.22

Finally a gearbox worthy for a fast and furious quater mile race.

Illy [tekijä] 31.5.2021 klo 3.44

Nope, you have to choose the gear yourself.

ACE 31.5.2021 klo 2.46

is it automatic?

Illy [tekijä] 30.5.2021 klo 16.15

Yes, but it's not really needed for ships.

jwking52004 30.5.2021 klo 16.13

does thus work for large ships
