[MOC] Formula 1 Chassis

[SimplyLegoTechnic]

 

Привет!

Более 30 лет назад я начал заниматься Формулой-1. Еще до этого я начал строить из деталей старых металлических конструкторов.

Сегодня я по-прежнему смотрю «Формулу-1» и имею возможность строить что-то из деталей LEGO, а также использовать некоторые электрические компоненты других брендов.

Здесь я демонстрирую шасси, которое, по моему мнению, отлично подходит для сборки радиоуправляемых моделей LEGO Formula 1.

Вот простой пример внешнего дизайна. Вы можете посмотреть короткое демонстрационное видео:

 

Я не ставил перед собой цели создать точную копию — элементы моего дизайна черпают вдохновение из разных лет, от начала 1980-х до 2010-х годов.

Шасси в этом масштабе (с задними колесами 68,8x36 мм и передними колесами 56x28 мм) оказалось довольно легким и надежным, весом около 650 г.

После добавления внешних элементов дизайна модель весит около 900–925 г.

 

Характеристики модели шасси Формулы 1:

- 3-ступенчатая коробка передач;

- независимая подвеска всех колес;

- рулевое управление с рабочим рулевым колесом.

 

Для электрических деталей я использовал:

- питание и управление от BuWizz 3.0 Pro;

- BuWizz-мотор/MouldKing-Baggy-мотор для движения;

- Серводвигатель LEGO PF для переключения передач;

- Двигатель LEGO PU L для рулевой системы.

Nice model!

Like the mixed up body design, nose looks like from a Formula Student, tire size combination reminds of F1 in the 70s, rear wing F1in 2000s.

Could you show a render of the drivetrain/gearbox, I'm interested to see how you did that.

 

edit: spelling

I like the electronics layout on this, especially the placement of the buggy motor, one of those rare cases where the weird form factor fits the model nicely! Is there are specific reason to use a PF servo for the gear switching? Couldn't that be done with another PU L motor (easier to get nowadays)?

Oh yeah, I was hoping someone else remembered what different parts of Formula 1 cars looked like in different eras))) Thank you!

Thank you!

This is one of the most compact and functional MOCs I've ever built. I finally managed to keep it under one kilogram and still have enough traction for a single buggy motor.

Why a PF-Servo? Because it's a BuWizz...

BuWizz 3.0 more or less controls the steering system using LEGO PU-motors. That is, if you can accurately calibrate the steering.

There's no fine-tuning option. And in RWD models, very precise zero-point adjustment is essential.

I managed to calibrate it after the 125th try...

 

However, BuWizz still doesn't have a proper fixed-angle switch (see here). For dynamic play in real conditions, the precise position of the shaft with the clutch switch in the gearbox is important.

Therefore, the only RELIABLE and truly functional option on the road is a PF servo with its precise 90-degree rotation.

It's worth mentioning that, when combined with a gamepad, the Buwizz app allowed for quite adequate control of a fairly fast model. Fast for LEGO of course.

To address the problem of growling at high speed, I rebuilt the front suspension, adding negative Caster. It looks more than decent, but I didn't bother redoing all the videos and renderings.

Great chassis! Actually it somehow reminds me of a formula student car (no offense)

Maybe-maybe))
It depends on what kind of exterior you put on this chassis)

Oh, I fully understand you :) Indeed, manual steering calibration is a really missing feature of the app..
