Page 3: Building the Suspension

   

Here is the formed aluminum sheet metal chassis which forms the backbone of the tank assembly.  The picture on the right shows a pair of brackets which support adjusting screws.  These screws will be used to push the front axle forward which will serve to tension the tracks using the front sprockets.


   

These cast parts are the suspension trailing arms.  The slot on the inner end connects to the rectangular torsion bar (a simple steel plate) shown which supports the weight of the vehicle and allows articulation over obstacles and terrain features.  The serrations you see on the spindles are all that holds the road wheels on.  A flexible rubber bushing will be pushed over these serrations and act both as a wheel bearing and a retainer.  The picture on the right shows the seven arms installed on one side of the chassis.  Each has a bump stop which limits the maximum possible travel.


   

These pictures show how the torsion bars work.  The picture on the left shows the brackets bolted to the chassis which serve as end locks for the torsion bars.  The torsion bars insert into the X-shaped recesses.  The reason they are X-shaped is so the same part can be used on both sides.  The right hand picture shows all of the torsion bars installed.  Note that the left and right side are offset slightly in the longitudinal direction.


   

Here we see the parts that make up the faux shock absorbers.  These are just for show since the piston just slides freely within the cylinder.  On the real tank these would be filled with fluid and act as dampers.  On the right you can see the installed dampers as well as the 4 return rollers.


   

Here are the parts to build a road wheel.  Each of the seven road wheels per side is actually made up of dual wheels with a gap between for the track guide.  Each is comprised of two wheels and two rubber tires as shown.  The picture on the right shows the completed suspension.  The chassis can now roll freely.
