Lego Mini Trial Unimog 406/427 MOC

[dpi2000]

Pan Dong presents. 

New mini truck, they are based on Unimog trucks. 4 wheel steering, this function is the focus of the building. Short wheelbase, portal axles, lightweight body. Two chassis models, like a RC car, one has server motor for steering, the other linear actuator and M motor . But , Both have the problem of turning to the imaginary position. L motor x2 for drive.

I hope you'll like it.thankyou for watching.

 

 

 

 

樂高科技迷你卡車,Unimog 406/427，董攀設計，謝謝觀看！

 

這次拼裝的重點，在相對較短的軸距，實現四輪轉向，然後輕量化車身結構，模擬RC車的懸架扭動姿態。有兩種底盤模式，一個採用伺服馬達轉向，另一個是小推桿加M馬達。兩個L馬達驅動，RC輪胎。四輪轉向真是靈活很多，攀爬時候的優勢明顯，不過因為前後各採用兩組萬向節傳動，導致有明顯的虛位問題。伺服馬達轉向，效率直接，但是轉向有類似軸效應現象，車頭會左右擺動。小推桿加M馬達的組合，姿態很棒，不過向上攀爬時後橋壓力大，還是建議採用不轉向的後橋，會更加結實可靠。

Interesting portal axle solution, but unfortunately I do not understand Chinese (under Movie URL)

Very advanced model, congratulations for it!  

I really would love to see Building Instructions, or at least detail photos about the axles, and the chassis, please?

The little turntable portal axles has been modified in these two days,more reliable. And, thanks,tractor tires from Russia! Perfect；）

Fantastic! I like the portal axles, but I wonder whether 20t bewel gears holds up without skipping since it is only supported on one side. I guess it is really capable as it should be quite light. Can we expect a video?

Best regards,

Miha

Haha,Thank you!

Occasionally there will be a tooth beating,especially  these two gears on the rear axle ,12t/20t(brick yellow),not happy about that.Video takes some time,you can look at this first.

Looks pretty cool. Considering the size of the obstacles, the performance is still great.
