Also could use the Christie suspension system on the top front track wheels as a idler to keep the tracks taught or tight limiting tracks coming of tank assembly.

On the original the pivot for the rear roller would be the sprocket axle and gears from the axle to run the rear roller and steering on the front bottom roller, so that it could drive on to it's tracks like a car. This is not needed as steering from the drive axle would suffice.

🆒!

Good model, could use pin bearings instead of ball but not needed as not heavy duty, rubber on track wheels and damper along with suspension. To give extra smooth drive.

Very true! The ball bearings can become oblate spheroids after all the vibration wears them down.

Would like to see the working model in action.

Too much movement at the front end of the motor would destroy the bearings in the back of the motor.

How many motors being used and what voltage?
@denismorgan97422 жыл бұрын
If using 12v motor rig up 12v battery per motor would take a very long time to burn out if kept on full throttle, alternatively rig up 18v for medium amount of burst speed. A variable switch helps to speed up or slow down also not all motor's can do reverse polarity for reverse, please check before buying.

2 motors at 12V each.
@denismorgan97422 жыл бұрын
If running 18v on 12v motor could use tiny fish tank fan to cool the motor to prevent burn out of motor and slightly lower voltage.

Probably 12v mosquito axial fan
@denismorgan97422 жыл бұрын
1 fan on each motor

I am going to work on a similar project... if you open-source i think i can help you

It is open source as far as the video is concerned. That being said, all STL models may be downloadable for a small fee in the future.

Or even go three roller assembly.
@AvivMakesRobots2 жыл бұрын
Three is good, but 4 is more balanced.
@roymorgan8282 жыл бұрын
If the three was spread out more, you could have more travel or movement on roller closest to drive sprocket.

Really good detailed model, especially with the motion links all done. I have some comments though: 1) 2:18 Why are the swing pins on bearings on the inside AND outside? I think you should fix them rigidly to the hull 2) Will you not have a hard time installing those motors there, or wiring them? Are you sure those drivers can handle such large motors? Why do you have 2 dual channel motor drivers? 3) The 18650 holder appears to interfere with the body, and I think using a LiPo would be easier anyway 4) Are you sure the drive sprocket can be cantilevered out that far? I think motors generally come with pretty small bearings, so you may need something chunkier there. It kinda looks a lot like the suspension I got on my tank, though I built mine a long time ago when I was a lot more ignorant.

1. Yes, it can be mounted rigidly. I decided to use bearings inside, but I could have just used brass inserts. 2. I switched to a different driver which will be shown in the next videos. It can handle these big motors. 3. I made a new custom holder to hold 4 of them in series and it fits in. 4. It seems to be alright thus far. There is a brass insert and set screw to hold it firmly onto the shaft of the motor.
