The
above picture was tested with a normal TXT gearbox and rods.
Picture
A shows wheel travel of normal TXT. As you can see (B, C), more
wheel travel is possible by changing the position of rods.

Less space between upper rods and lower rods make more wheel
travel possible.
The orange box in the bottom picture shows A, which is an angle
of ball-end, and B, which is the width between the upper rods
and lower rods.
An angle of wheel travel increases as the width of B decreases.

Larger
wheel travel was possible with same position of rods.
The bottom picture shows a different position of the ball-end.
The gearbox has more wheel travel by switching position of the
rod from outside
to inside.It was a result of decreasing interference between
the rods.
But it doesn¡¯t mean the inner side of the supper rods always
increases an angle. The point is, to make less interference
between the rods.

Longer
rods make larger wheel travel possible.
|
The ball-end also plays an important
part in wheel travel.
Generally different types of ball bearing have a slightly different
limit of angle.
If the one side of the ball-end has a 3 degree difference,
the whole rods makes a 12 degree difference in wheel travel.

Above picture is movement of gearbox from
side view. The gearbox vertically moves up and down.

| The relationship between a rod and a
shock also plays a very important part of a truck. |
|
|
|
|
| |
|
|
|
A shock
is directly
connected to a rod.
|
The
safest and easiest form is directly connected to a shock and
a rods.
But the vertical position of a shock makes a small wheel travel.
|
| |
|
|
| Above picture show a relationship between
a shock and a wheel travel. |
| A, movement of a shock and a wheel
is the same. |
| B, the shock is placed in the middle
of the rod, a wheel moves twice as long as a shock. |
| Picture C, in this situation, the wheel
moves twice as large as in picture B, But the shock needs to be
strong to stand the body. |
| |
|
Beyond all of these, we¡¯ve got through the
formation of the wheel, rod, and shock.
I tested them individually so there is no absolute result for
it. But if I make a conclusion for it, the wheel travel should
be balanced.
The perfect formation is a balanced formation, not inclined
to one or the other side.
