Spring Powered Toy Car
« on: September 28, 2018, 09:55:14 PM »
Hello,

I've found a nice Toy Car here.

https://www.pamono.de/limited-edition-toy-car-von-wouter-scheublin

https://www.scheublinlindeman.nl/toy-car.html

But the price isn't mine  :o so I've design my own toy car.
I used some other spur gears in Modul 1.
Original are some 9 teeth used, I've taken 10 teeth because I don't found any 9 teeht spur gears.

Regards Toby

Very clever mechanism, pull back to wind means no ratchet or key. Looking forward to seeing it built!

Wow, pricey little thing isn't it? Clever yes, could be built for far less than that asking price.

Very cool Toby! If you decide to share those plans, I'd be interested! :)

Hello,

I tried to print a prototype 3D.
Unfortunately, the model with Modul 1 gears has become very small.
At the moment I'm printing a model 1.5 times bigger, so with module 1.5 gears.
I think it will have such a bigger size.
Here's my quick and dirty drawings.
If dimensions are missing, just ask.

Since I created the model in 3D CAD, the 3D files and DXF files can be offered on request.

Now I'll see if I get the model 3D printed and mounted.

Greetings Toby

Hello,

Unfortunately I found a small mistake.
The chassis middle is too long at the back. It hits the small pinion.

Correction attached.

Greetings Toby

Toby:

If you're thinking about 3D printing the coil spring too, I wouldn't recommend it.  I found out while working on my rubber band gun that 3D springs aren't all that "springy".  If you make them thin enough to flex like you think they need to, then the spring is too soft.  If you make them thick enough to provide the required spring action, they won't flex too many times before they break.  Maybe if you were printing in nylon they might work, they definitely won't work with PLA and probably not with ABS either.

Hello,

I finished my first prototype.
It actually works pretty well.
The printed parts are not so accurate, I had to work a lot.


Here is a video of the function.

Hello Toby,

Your video does not show up.

Your prototype looks good in the photos.

Have a great day,
Thomas

Great little toy  :whoohoo:

The video shows in Chrome but not in IE - a problem seen before here, haven't got a clue, but seems to remember that they discovered that it is a question about how you add the video here.

Best wishes

Great little project Toby!  So are you going to make it in metal now?  BTW, the video worked for me....Windows10 and Edge.
