Title: Tracked Vehicle Control Arm angle?
Post by: Avadon77 on November 08, 2016, 11:01:41 PM

I'm building a tracked robot and trying to figure out what angle the axle arms/control arms should be set at? I measured the M1 Abrams tank and the road wheels are all set to 15dgs except for the leading wheel which is set at 40dgs.

But then I looked at other robotic tracked vehicles and they look to be around 40-60dgs. Is there some special angle? Of course this dictates how the suspension will work as well.

any clue what angle these axle supports should be placed at?

These road wheel arms on these two robots (Green is FIRST robotics team robot and the other is a Darpa Suspension robot) have a much higher angle.

So I'm wondering should the arms be much lower like 15dgs on the Abrams and other military tanks or should I be much higher like many other robotics chasis? and what is the difference?

Thanks,
