Strengthening U-Joints
Btotherad posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Okay, I had a quick idea that has not been completely thought out. So excuse the brevity and the stupidity if present. The dreaded CV joint. The haunted U joint. I had an off kilter idea I have yet to try out and didn't want to forget. I'm a loooooong time lurker here and almost forgot I had an account. Here's my solution. Has anyone here tried heat-shrinking the joints? If using a malleable type of shrink, it should still allow movement, no? And if this is not practical in theory, what about heat shrinking to the wheel hub? Maybe this is too quick of a thought but maybe would be valuable to others or possible spark investigation. -
So after 3 months of working in another town, away from my precious bricks, I am back! I had to return the 4 borrowed wheels from the fox, so I came up with an idea to make a smaller 4x4 off roader with the same amount of power. This is the crazy result: If you look from the side, you can see the model is quite short for its size, which is good for offroading. Also notice the 8 hard shock absorbers giving this beast a lot of suspension travel. There is even an interrior, which can be accessed via gullwing openable doors: I am very proud of the styling, there are no major gaps and almost no straight or perpendicular lines. Now for the performance... I found a way to harness the power of 2XL motors/wheel without breaking gears (too often that is). Each XL motor is placed on opposite sides of the swinging half axle so that their torques cancel each other out, therebye having minimal effect on suspension. The only gears capabale of withstanding such torque at perpendicular angle are of course knob gears. The hub assembly is simillar to the one used in the Fox, but with built CV joints capable of handling 2x the XL motor torque. But even so sometimes an 8 tooth gear may fail if a foreign object is jamed between gears and the wheel is blocked Even though the models tends to kill gears on occasion its still quite relaible for its massive weight of some 4 kilograms. Dimensions: Length: 47 cm Width: 25 cm Height: 21 cm Here's the video of the Jaguar in action: Oh and of course the most important picture of them all Though there's not much to see, but I like the arrangment of the components, its clean.
