LDD: Mercedes Actros 8*8 truck trial "polar version"
I seriously like the recent Lego city polar series: well now, it became even more serious
About this creation




On seriously cool series of the last years, in my opinion, is the Lego City polar series. I really enjoy set 60035, as an example.
Well, now, here is a little larger example, in full trial truck livery. I present you a 2016 Mercedes Actros 8*8 polar version.



God I love those chunky wheels. Designed, as allways in scale, but with full trial truck capabilities, the vehicle became much to high. Solution indeed : BIGGER tires.

I already had a quite good trial truck drive train design, and I knew it would become an Actros, but then Lego came with 42043... sigh... About one year later:
No sweat, this is my interpretation...




Technical details : 5 motors, of wich 2 XL:
The XL are for moving, one for the front, one for the rear, indepently.
Front and rear drivetrain don't have a differential between first and second axle, but do have them between left and right.
One motor for operating a simple high-low gearing. Well, as front and rear move independently, actually two gearboxes...
One motor for the steering, of course with ackermann. Motor is mounted on the front drivetrain.
One motor to lock the rear differentials (front allways stays open).
Axles are pendular, but drivetrain itself have a up-down capability. It should operate like all wheels are indepently sprung. (+ - 2 brick travel)
Suspension is like "leave spring", and actually 2 flex rods operate them. Proven succes...




Cabin : my interpretation of an 2016 Actros. kept it as generic as possible, as is the interior.
Doors do open...



Engine. V8, off course, but mounted way too high, chassis and suspension were priority.

Ziet er weer mooi uit! Cabine is goed herkenbaar en de aandrijflijn en wielophanging zijn indrukwekkend. Erg leuk!

This is really awesome. The construction and design of the chassis is excellent. The Mercedes emblem takes the cake! Nicely done!

If you want me to be rude: YOUR TRUCK IS A BIG PIECE OF engineering. Well done. I really like the way the suspension works. 4/5

Extremely well done. Thank you for sharing. Great use of the tumbler tires.... they are exactly what I would have thought would be on an arctic-explorer type of vehicle

I love the last pic - dancing truck! Great work here, it seems like it'd work well and it's better looking than most TTs. Orange ftw!
