Description

Here are the road wheel and suspension parts that go along with my tank tracks and drive sprocket model. I am not going to post the entire tank build here. My intention is to give someone a head start if they want to design their own tank. The tapered plug is to be inserted into the end of each suspension arm to hold the ends of the spring in place. The springs that I am using are 304 stainless,1.6mm wire, 18mm O.D., 70MM free length, currently available from Amazon. If you need to use different sized springs, you can design your own plug to adapt your particular spring. This tank is a short track design using 48 track links per side and three road wheels. If you want to build a longer version with four road wheels per side, just skip the rear suspension and build two more front suspension sets.

That's great to hear. I would love to see more pictures sometime. Also, I love the motors.

Is there a support piece for the real wheel?

@bowser

Not currently but I would be glad to add one

@bowser

I just added them to the print profile, Plate#5

Replying to @bowser :

Thank you so much! These are fantastic models, btw. I've printed and assembled one of the tracks already, and all of the bogie wheels and suspension parts. I have about 24 hours of printing left to finish both tracks and parts are arriving like those m3x45 screws, springs, etc. Motors next week! :) I'm out of boost credits but will soon be boosting both of these models.

this looks great! me and my son will build a tank with these.can you share a picture of how the rear wheel is mounted? I don't understand the recessed screw holes...

The designer has replied

@bowser

I understand your confusion. The skid plate and the sides of this tank are cut from 1/16 inch 6061 aluminum sheet. I used rivet nuts as threaded inserts to mount all of the suspension bits to the chassis. THe recesses are actually clearances for the heads of the rivet nuts. Here are a few more pictures of the chassis showing the aluminum parts.

Replying to @bowser :

Ah, that makes sense now, thank you! One last question - I don't see an STL file for the rear wheel mount (rear wheel adjuster). Could you please also provide it? Thanks

@bowser

Replying to @user_2295158208 :

Sorry for the omission. I have updated to include the rear wheel adjuster as well as a mirror image for the other side.

hello bowser. could you please let me know the overall length of the tank tracks you have mounted to your tank body? the distance between the hubs would be nice to know. I am using the tracks for a small project at university, as this are by far the best modelled tracks i have found so far.

The designer has replied

@bowser

Hi, I am using 48 track links on each side. Here is a quick sketch of the center-to-center dimensions for the wheels. You will want to put the trailing wheel on an adjustable mount, so that you can tighten the tracks accordingly. I would be excited to see a picture of your project when you get it rolling. Also, if you are using my belt drive transmission, please be advised that I will be posting a modification soon that uses 3mm belts instead of the 2mm belts.

you sir are a genius and an engineer. i have been waiitng for this !!! I am just someone who prints other peoples ideas, i cannot 3d :( thanks for this!!!

@Sh4dow_33

Start with something simple, I am still learning but I am far better than I was a few months ago

@BEI_Tech

Is it correct in the description that it is M8 and not M6 that is used for the suspension? Because M8 seems abit overkill for this 😅 Just checking before printing and ordering screws
