In the first gear, you can feel more resistance when you push the car. When you go to the 8th gear there’s less resistance and the car can go a bit further with the same push with the first gear

Question: I don't think the numbers and ratio calculations mattered to me as much as the actual mechanism. I think the way it was presented was a bit confusing with the arrows and all, and the concept at some point was just left behind in favor of talking about the numbers. My point is, I want to learn how to design a gearbox mechanism, rather than learn the Technic Sian model's gear ratios. Do you have a good source for technic gearbox function? The problem I ran into occurs at 4:37. Until this point, it was clear where the power is going. But the arrows in this section are extremely confusing, because not all of the gears are properly visible, and your voice is just saying "here to here to here" without referencing anything visual. It's unclear whether the torque leaves the confines of the "box", the bluish gray frame, into the external gears, or if there is an additional gear inside the box that transfers the power. Beyond this point, you stop talking about the mechanism of the actual gearbox, and only talk about the multiplier and the ratios. The complexity I was trying to understand is in the 4-transmission gearbox.

Thank goodness for your detailed video. From this, I realized I had the stud on the green stepper mechanism reversed, such that the R side would not rotate through speeds 1-4, and would not engage the left side every 1 revolution. Pulled the chassis in half, flipped the stud on the green stepper around, and voila...works as you advertise!

My gearbox has a problem. Shifting gears from 8th to 1st works fine, but the next set of shifting from 8th to 1st doesnt move the engine, it alternates between this. Does this happen because I built it wrong, or is it really supposed to do that? Thanks

That's so weird that it has essentially double the multiplier gears. Essentially the whole gearbox is more like a truck gearbox than a car one but very interesting to see how they did it.

Very cool video! I'm making the Sian at the moment. While building it I could kinda see what was going on in terms of the two sliding pieces that engage with the otherwise free red wheels... But trying to actually manipulate everything and see the ratios is pretty tricky. But once you get the front axle assembly on it all comes in to place and you can manipulate the sequential shifter: so yeah don't be discouraged if you're thinking "hmm I must've done something wrong" or it won't turn or anything... it all comes together :D

great video ! maybe someone has an answer for me: i have a problem while switching from 4th to 5th gear (or frfom 8th back into the 1st) the mechanism as itself is working, but with the shifter behind the wheel i cant skip into the 5th gear. the black part that turns the yellow wheel always slips over it during the attempt. with my fingers i can turn the part, but i recognize a significant bigger effort. I thint thats the reason why it doesnt work with the pedal shifter. the question is: do you also feel a needed bigger effort? from where it results?

@jltworks3167 4 жыл бұрын
8:00 definitely fixable. Replace it with a solid 24T gear. I also fixed the issue where you had to push the chiron quite a distance for the engine to work, by replacing the 24/8 gear connection with a 1:1, greatly reducing timing. Does the Sián work in the same way? Do you have to push the model quite far for the engine to work? If so apply that same fix I just mentioned on the chiron, behind the rear axle. Great explanation!
@Unbrickme
@Unbrickme 4 жыл бұрын
Yeah I understand its fixable, but it would take too much time to dissasseble and reassemble, Yeah the Sian works the same way. Thanks for the tips! However, replacing the 24/8 with 1/1 will severely mess up the gear ratios, and the resulting speeds won't even be sequential

Can you keep upshifting that gearbox indefinitely (use same side of the lever to shift)? the gearbox will still go from 1st to 8th and then repeat, but there is nothing stopping you to use same lever to shift again at 8th?

Great video. I do have 2 questions about this gear box. (1) it seems moving the gear lever towards the front is actually the forward gear which is opposite of real cars. Is this expected on this set or I made a mistake in my build. (2) if I manually turn the black gear in the cockpit, I am basically only able to turn the wheels in 1st and 2nd gear. In higher gears there's great resistance that i feel like the axle is very stressed. Is this correct?

I've just done step 250 where you put on the second axle assembly. I wanted to play with the engine and transmission a bit, so I put the four wheels on and tried rolling it on the ground, but now I have encountered a problem where sometimes the gear shifting doesn't change the rate of the fake V12 firing. Also, in some gears I can move the wheels one way but the other way is locked up and strips the gears if I try to move them. It also sometimes locks up in both directions. I have undone step 250 and taken the second axle back off to try and isolate the problem but it did not change anything. I hope I explained my problem clearly enough. Any suggestions are appreciated!

Great explanation! However I found that in my car the switching system does not function as shown in the video, and I am not able to find the reason for this error. The paddle can only move once which changes speed once but it cannot go again in the same direction, it can only be pushed from the other side. So pretty much it only switches between 2 speeds. I'm trying to figure out where the cause of this error is and how I can fix it, but it seems impossible to reach anything without having to tear down the car to get to the mechanism.

I love this! It all makes sense now! I have a question: is 1st gear supposed to be harder to turn? I had to build the gearbox a second time, because it was kinda rough turning it after I connected it to the rear differential, because it had A LOT of friction. Is that normal? I don’t remember 1st gear being that hard to turn on the Bugatti.

Mine in the 2nd and the 6th has a big frictions somewhere. I couldn't figure it out and I didn't want to disassemble the whole car. (No insta.) Any idea? I have only one idea: in 2nd (and mulltiplied 2nd) 10 more gears move actively than in 1st or 3rd, and the 4th is already slow enough and engine brake does't effect so much.

I could carry out 2 kinds of solutions. 1) disassemble, (change a part), assemble. 2) WD40 (Or water because dust may increase the problem.)

@Preston Varner I believe that you should get the Bugatti, but please be very careful when assembling the gearbox of the bugatti. Also replace the clutch gear in the bugatti with a normal gear. The gearbox in the lamborghini has more refined pieces for some mechanisms and it gets stuck way less. Although if you prefer the bugatti aesthetically more, then get the bugatti

I don't think I can make a video explaining that set but I can give you the gist of it. Essentially there's 7 different axles all connected to each different function. The axles have driving rings which can connect to either the clockwise direction or counterclockwise direction. When you engage the driving ring into the different gears, each independent function activates with the gearbox and just one motor

Hi. I found 2 problems, the first was a “green” part with a little part in wrong way. Problem with changing gear. That problem is fixet now(I fount a video to this problem). but I have another problem with the tires. The tires rotate approximately only 2 centimeters in any direction and slow down, all four tires rotate in the same direction. but I do not understand why they stop and it is as they are a spring when they stop in any of the 2 directions. it returns to the opposite direction. My Sian can’t run more than 2 centimeters ☹

could be a variety of different causes. Here are some probable ones. 1) differentials are placed the wrong way, simply flip one of the differentials. 2) another lego piece fell into the gearbox and got stuck, causing the gearbox to jam, 3) gears in the gearbox are placed incorrectly

​@@Unbrickme I had only one gear left. Yesterday I removed everything I can to see the gearbox, and compared with the instruction book, every gear was in place. So I guessed the remaining gear was an extra piece. If switched to reverse, everything works. but only if I switch to forward, it looks like every second speed not moves the pistons. Edit: figured out, the missing gear was really missing but not from the inside, but rather the outside of the gearbox. IThe missing gear was not seen in the bottom view, the right axle near the output, there is a gray gear after a long red connector, and next to it, outside of the frame there should be another gray one, that was missing.

@Unbrickme
@Unbrickme 4 жыл бұрын
I believe the gearbox in the bugatti didn't work because of the improper model design. There's a clutch gear, and there shouldn't be one. Clutch gears slip very easily, too easily. I reccomend the lamborghini because the gearbox is more refined, the model is newer, no clutch gears, and it looks cooler and has scissor doors.
