Adjustable tank suspension (Strv 103)

[Tomas TECHNIC]

It was a big challange to build adjustable suspension for this tank/destroyer.

My first idea was to use only one PF M motor for suspension tilting but it was not posibble (for me ) to make needed gear reductions in such a small place. So I used two PF M motors (one for first four wheels, one for second four wheels). Only one gear reduction for each motor was needed in this case. This solution brings nice advantages - you can also adjust tank height. For suspension I used torsion bars. It is the easiest way to make it.

 

For more details look at the video. (time: 1:10)

If you like this MOC you can look on outdoor video.

Very cool Model, I always liked the look of these TDs. What kindof mechanism are you using for the Lowring system?

Thank you. I joined gear wheel on the torsion bar and thanks to the worm gear you can adjust rotation of this torsion bar.

Oh wow, thats why you used bar suspension. I personally dont like twisting my axles, I cringe just thinking about it. I would probably have used small linear actuators. But if you are fine with it, its ok I guess

Don't worry, I had this tank on a stand to save axles.

i cringe when they twist, but then i remember they go through heck every time i use them in a drivetrain so i suddenly stop caring so much about their wellbeing... also theyre pretty inexpensive here in the us so if i do deform or break a few i can just buy more

I loved the videos when you posted them. You did a great job with the suspension and the overall look of the tank.

I really like the concept of Hydraulic Suspension, i am really curious about the mechanism used for that... for a week i tried to reproduce something similar but without any of the results, always something was too stiff or the axles from front/back moved both in a synchronous manner ( i am talking about wheel 1 with 2 and 3 with 4). its still drives me crazy

 By any chance you could share some details? I would much apreciate.
