Tumbler Buggy
Small, fully suspended buggy. Very good power-to-weight ratio.
Datasheet:
Completion date: 09/05/2007
Power: electric (wire-controlled)
Dimensions: unknown
Weight: 0.65 kg
Suspension: dragged axles on shock absorbers
Motors: 1 x RC, 1 x 2838
Briefly inspired by the vehicle from Batman Begins the movie, called Tumbler. The only real reference is the rear axle actually, with two wheels on each side.
The drivetrain, consisting of a single RC motor, few bevel gears and a chain, turned out to be surprisingly effective. It’s been most likely thanks to the lightweight body, low center of gravity and the advantage of bevel gears and chain over the traditional gears, as they generate much smaller backlash and thus much less energy is lost. The buggy is very manouverable too, with a very good steering lock and a well-calibrated speed of steering. I have been testing a version with kinda ‘off-road’ wheels, but the wheels with the flat tires offered a considerably better performance on the floor. Simple as it was, this car turned out to provide lots of fun while driving around.
@tristan
the bottom view should be sufficient to work out your own version. 🙂
@tristan
Sorry then. You have Google and Wikipedia – help yourself.
i dont understand the most of the things
@tristan
I gave you the motor’s name and displayed it on the photos, what more do you expect?
i dont know what is this RC motor .
@tristan
Isn’t most of it explained in the text above or shown on the photos? The motors types clearly are.
what are the motors you used ?
can you explain those things (HOWITWORKS) : the remote the steering the suspensions . what for motors did you used ? how the rear wheels are they powered ?
@tristan
Sorry, I can’t.
without the bodywork just the interior
can you send me instructions of the tumbler ?
because i wanna take the design to build a car for the outdoors
that deems geared down really low
@Jeffrey D
There is a whole post on compressors in the Ideas category.
So I need to build a serious beast of an air compressor, like 6 cylinder +. I have been using Pf XL motors geared up to drive it and I’m not getting the airflow I want. Do you have any experience using the 5292 buggy motors with compressors?
@Sariel
You’ve come a long way since then!
It’s not independent. I think back when this buggy was built I did not even have the parts needed for a steered independent suspension.
Is the front suspension independent (like the Tumbler), or does the front swing arm go all the way across? It looks like it is solid.
