Technyk32231's MOCs, WIPs, and ideas

[Technyk32231]

Ok, here is a gearbox I made. It was made to be realistic, so it only has two shafts, one for input, the other for output. I had to make two types of gears myself, a 20 tooth clutch gear and a 24 tooth clutch gear. The 24 tooth clutch gear was cut off of an old type differential, and the 20 tooth clutch gear was made by hollowing out the center of a regular 20 tooth double bevel gear, cutting the teeth off of a regular 16 tooth clutch gear, and putting the 16 tooth inside the 20 tooth. The gearbox is a 6 speed + 2 reverse gearbox, so 8 gears total. Really though, it's a 3+R gearbox hooked up to a 2 speed transfer case.

The picture is too large to embed, and sorry for horrible quality, it was taken on my mobile, and gearbox is long disassembled. Maybe sometime I'll rebuild it and take better photos.

Here is a car I made a while ago to teat steering and suspension. I lost the shot where it isn't upside down, sorry. These photos were also taken on my mobile. I'll take more pics of the front axle later, the model has already been disassembled, but I kept the front axle for future projects. These photos are also too large, so I'm putting links.

This is a good WIP photo, taken of the first version of the front axle. Later, this axle would lose the shock absorbers and gain improved steering geometry and suspension travel.

This is the new front axle. The vertical 6L link is for suspension. This model has all-round floating solid axle suspension with transverse torsion bars. As you can see, this new front axle has caster angle. I couldn't get the shock absorbers to work correctly, and I wasn't satisfied with the suspension travel, so that's why I switched to torsion bars. It works very nicely. The caster angle is achieved by simply moving the upper links backwards. The front suspension is a triangulated 4 link type, and the rear suspension is a 3 link with a bionicle ball joint. This model has no fake engine, as the main focus of this model was steering and suspension. Plus, the front suspension took up too much room for a fake engine.

Here is the underside shot. The center of the model is held together by the floor and "doors" entirely, forming part of the central body, almost like a unibody construction.

Oh, and here is just a strange mechanism I made. As the input rotates, the output "punches" in and out.

The other day, I made a coupling that transmits rotary motion, and also handles lateral, longitudinal, or angular displacement between the input and output shaft, and can handle any of these at the same time. I will post more pics and maybe the .lxf later, once I get to the computer.

Sounds interesting, can you post an LDD screenshot once you get your computer?

[Technyk32231]

Yeah.

Ok, so here's that coupling I was talking about.

Could you post a screenshot? I don't have LDD.

[Technyk32231]

The screenshot is right there.

OK. The screenshot was tiny when I posted.

Might have to try this, it looks very cool!

The only problem is that it's big. However, it can be made much smaller, and can handle a reasonable amount of torque.
