The truck so far, from front. Also seen is my NZG model, from the
same angle. |
 |
Underneath... |
 |
Close up of rear axles mounted in the chassis. |
 |
Front axles straight ahead. Also shown is my NZG mode from the same
angle. |
 |
Full left lock - 80 degrees of turn possible, lock to lock. |
 |
The superstructure base and turntable in-situ. |
 |
From my Solidworks CAD program, showing the overlay of chassis
structure and truck details. Also shown is the front stabilizer ram (not
put into the 'real' Meccano model let, but I had to design enough room
for it!). |
 |
Where the gearbox sits. Visible from this angle are the leaf springs
and some of the steering rams. The steering rams will be shown in more
detail once the full servo assist feature is built into the model.... |
 |
The torque arm for the rearmost rear axle in place, showing how it
fits to the chassis. |
 |
The front axle knuckles in view, showing the 4 bolts that hold the
wheel rims in place. The front most knuckle has the brake drum and
holding bolts in place. |
 |
The interesting part - each steering knuckle has drum breaks,
activated by bowden cables. (Yet to be fully hooked up). The return
spring is visible. |
 |
Taking apart the front axle. Exacto large diameter shafting is used
to support the wheel rims. |
 |
Wheels set for straight ahead, showing linkage arms that control
steering angles between the 2 front axles. All basically per the real
machine. |
 |
Wheels set for a left turn - full left lock. |
 |
The link to the steering box. |
 |
Getting from the steering wheel to the link arm to the axles. View
from top. |
 |
And view from underneath. You can see the dual contrate based
differential arrangement, that will be used to control the
servo/switches to operate the servo assist. |
