I have been working on the power-shift transmission. This is an experiment and needed some proper preparation, including calculating ratios, making accurate drawings, etc. Quite the challenge!
The Clark series 6000 is the example.
I omitted the forward/reverse clutches. An electric switch can take care of that and it saves space.
I use leather as clutch material.
The middle shaft on the left is the input shaft and I still need to figure out how to connect that to the motor, an 540 CRAWLER BRUSHED MOTOR 80T.
I am still making all the components and I am not sure if it all will work.
Making the frame demanded a lot of accuracy. My Southbend was up to it! I did a lot of measuring at every stage to make sure things will fit OK.
So far so good. I plan to control the clutches with 2 servos. W'll see how that works out!
