F1 Seamless Gearbox Pt4 

Thanks! I just saw that episode and was like hey that looks like my gearbox 😂

​@IndeterminateDesign He referenced your channel verbally and said he would link it but seems he forgot to add the link. Im glad I spent the time to find your channel! What an awesome project!

Came here after driver61. Good work keep it up 👍💪

Maybe it was an oversight by him but I noticed that he didn't too. Not hard to find this channel because he did say and show this channel name.

We are sad human beings, and pretty well a drain on society :)

Thank you very much!

Thanks! I would like to try it in a car like my Mk1 Golf. The design could be simplified a lot since it's not an F1 car. But I always comeback to a dual clutch gearbox is probably cheaper and easier to implement, even if it is heavier.

Glad you liked it!

Dig deep my Man 🤣 something like this would be many hundreds of shekels

No. It would be awesome in metal. A lot of the design was optimized for 3D printing, so it would take some serious changes around the bearings and everything.

It could be machined from metal as a model. It lacks a lot of things like proper bearings, lubrication and the tolerances are far too large for use in a vehicle. You need some strong and fast actuators too. I thought about designing my own 6 speed sequential but for the money it’s not worth it. A good name brand sequential gearbox is $20-25k which is less than you can make a one off gearbox for. I had a lot of people want a gearbox for a shifter cart but I think it’s easier and more reliable to just buy the internals from a motorcycle gearbox and install them inside a case. 🤷

That’s would be cool, and you could get a lot tighter tolerances so it shifts better. For me it was just too much time and money to try that.

Since this is driven by an electric motor, I can accurately control the torque with the microcontroller. It would be much more difficult for real F1 gearboxes and they use a series of MagCanica torque sensors that can measure microscopic bending in the output shaft.

When I designed my previous F1 gearbox I met an F1 test engineer on Reddit. It’s done for durability. The gearboxes have different shift modes depending on how hard they want to abuse the gearbox with the shock loads. I don’t believe the wheels will see much of a cut in torque given the inertia of the drivetrain. It’s also a common feature in most electronically controlled sequential gearboxes like those used in rally racing.

@@IndeterminateDesign That makes sense; most normal sequential gearboxes use either a spark/fuel cut or timing retard. In F1, they could also use the MGUK to pull torque. I can see them having a conservative mode to preserve gearbox life and a full attack qualifying mode. I know some high end time attack cars with DCTs that shift at full torque; the gearbox and clutch just have to live with the shock load. Wear doesn't matter that much if you only need one lap at full send.

@@ZergZfTw Lo siento por responder en español (lo puedo hacer mucho más rápido) pero para mí esto no es una cambio "seamless". Es un cambio secuencial tradicional de los que llevan usando las motos desde más de 50 años. Una caja de cambio secuencial, gobernada por un desmodrómico que mueve las horquillas y los desplazables que bloquean o liberan los engranajes libres del eje secundario. Las motos pueden cambiar de marcha, solo cortando gas, gracias a la desmultiplicación que hay en la transmisión primaria (engranaje del cigüeñal con la campana del embrague). Al haber una reducción de rpm, no solo ganas longevidad del sistema, sino también mayor seguridad y efectividad en lo cambios ascendentes. De toda la vida en las carreras de motos se sube de marcha sin embrague, gracias a esta desmultiplicación inicial y a la distensión de la cadena en la trasmisión secundaria o final. Los ingenieros de F1 han copiado esto, al igual que los embragues multidisco por ser más compactos, eficientes y longevos... y luego dieron un paso más allá. Los coches de antiguamente, de forma habitual, no tenían o no tienen desmultiplicación, tomando normalmente el par el árbol de trasmisión, directamente del cigüeñal. Los cambios seamless utilizan otro sistema, que es muy parecido a los carretes de bicicleta, el piñón de la rueda trasera, con un sistema interno de cuñas y rampas que eliminan las horquillas y los desplazables, siendo más rápido aún que estos. Honda lo extrapoló de la F1 a MotoGP ¡ Que raro, Honda ! Les invito a ambos a investigar. Hay un vídeo de otro chico que ha realizado uno en impresora 3D y muestra su funcionamiento. El cambio convencional de un coche, con mando y varillas está por encima de 1 seg. El secuencial de una moto con desmodrómico en 0.5 seg y un seamless sobre 0.180 seg. Muchas gracias por la atención y buen trabajo y vídeo.

Just takes money, so much money $$$$

The F1 gearbox model is available on printables.com under indeterminate design. I don't know how well this would adapt to a motor cycle. It would be quite expensive to manufacture a custom gearbox like this and the control electronics would need to be much stronger. The disadvantage of this gearbox is that if anything goes wrong you will engage two gears and lock everything up. Check out this gearbox, it's based off the Honda MotoGP gearbox and is probably a lot better suited to a motor cycle. Unfortunately it will still be very expensive to reproduce in metal. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0GJrDS8-nbE.html

@@IndeterminateDesign I've got a lot of questions, I'm sorry. Would you be willing to answer them? Are the gears interchangable? As in, can I change the gearbox ratio? Thank you....

@@Brian-ks6kf Understood, thank youuu

Sorry, I had some weird audio issues. Video editing is something I'm still an amateur.

The Valkyrie AMR does have something like this, along with the price tag to match. 😂 These gearboxes shift extremely harshly, are expensive to build, and require expensive maintenance. For any road car or lower cost race car, heavier dual clutch gearbox’s , or a traditional sequential dog-box gearbox are a much better compromise.

@@IndeterminateDesign 👌

@@IndeterminateDesign Come to think of this, I've heard this seamless gearbox technology can make up shifting smoother and more continuous than the conventional type for the race bikes in MotoGP... It provides smooth and continuous torque while a rider is up shifting, so that it saves shifting time and tire wear. Many bike manufacturers even equip their super bikes with seamless gearboxes. But I'm not sure of these claims and advantages because I've not ridden a super bike equipped with this kind of gearbox before. Can you tell me about this?
