Euclid R-62 dump truck

Kerst, it's an amazing concept and build, as usual for you. Maybe the glitch is that you don't have enough machinery moving in this driveline!!! LOL!!! All the shafts, gears, joints, clutch packs, etc. - just a marvel to watch. Are you using servos to engage the clutch packs?
Your design would make a great 2-speed for highway trucks - much less gear slop (free play) than the Tamiya mechanism.
Reminds me of Clark transmissions in the real trucks, with clutch packs on the outside at the end of the shafts.
Anyway, keep up the awesome work!

Duh!!! Guess I should have reread your initial posts - Yes, you are using servos and Yes it is patterned after a Clark transmission.

Still, an awesome effort!

Thanks,

I hope to fix the problem by increasing the reduction between the motor and the gearbox by 20 to 30% and i will create space for another motor. If the reduction doesn't do it, an extra motor will! just like the real ones, they also have two engines.

Yes, I know about that rework stuff. My Payhauler had a 2:1 motor reduction so top speed matched the prototype. I have three speeds, real one had 7 speeds. I was short on power when bed was full of dirt, so changed to 3:1 - made a huge difference in low end power and seldom need the top end speed anyway, so all is good.

Do you have any in-process pictures of the u-joints you fabricated? Great job with them.
