This is a dual differential steered 6speed sequential RC transmission

Gear ratios:

1st - 60:1

2nd 48:1

3rd 36:1

4th 24:1

5th 12:1

6th 8:1

Images:

1-4 CAD renders of the gearbox from multiple angles ( TOP, Angled, RIGHT, HOME)

The large black horizontal cylinder is the main drive Motor for the drivetrain (3660 2700KV), and the smaller one is the steering motor responsible for creating a speed difference driving the large chunky planetary differentials on either side to subtract and add RPMs Thus allowing the veichle to steer.

5-6 note that the crossection images are a slightly older version where the shift drum is much smaller with different fork geometry, however this is one of my first posts so this is for just showing the transmissions internals.

5- crossection along the main two input and output shafts, in this section we can see in between the differentials in the center, is a motorbike inspired 6 speed sequential dog box controlled with a servo turning an indexing mechanism that rotates a drum and engages forks sliding gears with dog teeth that engage just like in a Honda motorcycle. Behind it there's the sift drum and forks.

6- this is a different angle from the bottom showing the shift drum, and across from it is the bevel gear set that the steering motor runs to the differentials.

7 these are the internals of the transmission exposed featuring the following systems such as:

- Driving

- Shifting

- Steering

Note, motors are not visible.

8 last time I posted this transmission it got misconcepted about it being AI generated and removed "low effort posts" . Image 8 and on prove that this is a 3D printed prototype, and this is all modeled by bare hands drawing sketches and extruding, lofting, generating gears and combining, a billion times into this unique machine.

Thank you for viewing 🔮.

If you have any questions about the prototype please leave a comment or check out my Instagram! Note: the video is a bit fast so feel free to pause and read the diy manual ( this is not advertising just want to show y'all a prototype I designed and now assembling!)

XV// This is a gearbox designed for a custom 1:16 scale RC T-80UW project we've been working on lately. First picture shows how the gearbox looks like fully assembled, Second image is the clearest angle we could get to show all internal systems like: Driving, shifting, steering. If you'd like to find out more details about it visit this insta reel that shows the manual, explainig the transmission and project in greater detail!at:
