Charbel Posted October 27, 2020 Posted October 27, 2020 (edited) Hello, I am sharing here an idea I got over a year ago: fix the paddles to the steering wheel in order to make up space and therefore make the supercars' interiors much cleaner. The idea might seem a bit complicated but thanks to the use of a mini LA, it somehow becomes much easier. Putting the LA through a mini turntable allows to transmit a translating movement while still allowing the mini turntable and therefore the steering wheel to rotate. The design I am showing uses @Didumos69 stepper. I am quite happy with how it it performs and how it looks even though it may not look like that inside a car. The process behind this took about 200 different designs and iterations and I was helped by @T Lego who will use this idea in his car...

amorti Posted October 27, 2020 Posted October 27, 2020 Looks great! It looks almost like you could have a height adjustable steering wheel here? Does the use of a LA cause the steering wheel to telescope towards the driver at all? Quote

Like astyanax said, the LA input will rotate the same amount as the LA's head so no extension of the LA. If the Axle were to be fixed, the steering wheel would remain in place - it's not connected to the head of the LA. In stead the paddles would go out of allignment with the stepper slighly if you'd turn the wheel. Quote
Bartybum Posted October 28, 2020 Posted October 28, 2020 Really promising solution. Can the MLA be replaced with some other assembly? Quote
Jurss Posted October 28, 2020 Posted October 28, 2020 Great idea! Steering needs to be downgeared somewhere later. This ratio could be too fast even for some sports car. Quote
howitzer Posted October 28, 2020 Posted October 28, 2020 Wow, this is genius! I love the novel part use. Quote
steph77 Posted October 28, 2020 Posted October 28, 2020 (edited) One thing is still to do…. Spoiler Build the moc that comes together with this great idea Edited October 28, 2020 by steph77 Quote
Woodpecker Posted October 28, 2020 Posted October 28, 2020 Cool design! What car are you going to use it in? Quote
2GodBDGlory Posted October 29, 2020 Posted October 29, 2020 Neat! Cool to see the linear actuator being used in such an unusual way! I don't suppose it is possible to make the steering column any shorter? Quote
Nazgarot Posted October 29, 2020 Posted October 29, 2020 Very nice construction, and genius use of parts! Would be perfect for a koenigsegg... _ED_ Quote
Gray Gear Posted October 30, 2020 Posted October 30, 2020 (edited) Wow, ingenious solution! I dont use sequential transmissions in my cars, but I would try to use this if I would build a modern supercar Edited October 30, 2020 by Gray Gear Quote

Timewhatistime Posted October 30, 2020 Posted October 30, 2020 Very great solution! There seems to be a small mistake/inconsistency in the pictures: The hole of the connector No. 2 in front of the device sometimes is orientated vertically (and holds a pin) and sometimes is orientated horizontally. The former orientation seems to be correct, imho. Quote
SNIPE Posted November 11, 2020 Posted November 11, 2020 Is there a way to have the paddles return to centre when pulled? Quote
T Lego Posted November 11, 2020 Posted November 11, 2020 3 hours ago, SNIPE said: Is there a way to have the paddles return to centre when pulled? Yes, however adding such application requires a lot of extra input force on the paddles, especially with this stepper design, which would make playing not very satisfying. Charbel and I have expirimented with many different stepper mechanisms that returned to the centre but those were either too bulky or weren't reliable enough. Quote
Aleh Posted December 14, 2020 Posted December 14, 2020 I built this mechanism abnout a month ago, it looked and worked fantastic, but when I installed it into the car, I discovered two issues: - I can swith only in one direction, forward, I wasn't able to return previous position. - When connected to the gearbox it has not enouth power to swith gears, I have to pull it too hard. If the second problem may be resilved, I wonder about the first one most of all. Could anybody please explain?

UPD: I saw the video once again - it switches in both side, but I/m able to switch only when the left paddle is pushed and the right is pulled (5L white beam is on the bottom). Quote
