Here I am after a long long time but you have to excuse me. After all I do have a child and a lot to do besides doing lego models but I squeeze in some of my time for Lego. Anyways this is something I finished a month ago but I never got the chance to take a photo of it. So here it is.
I thought I might do an all terrain vehicle with steering on both front and back wheels and make the 4x4 drive. At that time I didn't have all the fancy parts that would've made it easy. By the time I finished it I got as a present a Lego 8880 model. Ah what the heck! I didn't want to destroy it and put it back together again with the parts from the 8880 so I stuck with my initial model. I will use what I got as a present on another model.
On with the important stuff. I named it like I did because of the way I designed it. You might agree with me or not but it looks like something Citroen might have done as a concept design and this is just the thing. A concept vehicle. So As I mentioned it was a tough thing to do because I am not a scientist and a lot of these technics stuff... I do not understand the way they work but I am trying. Like it was a total celebration when I managed to make the 4x4 wheel drive and steer all 4 wheels. Steering was the bigger problem since I wanted to steer front wheels with a normal turn and back wheels less by 50%. After 3 failed tries I finally did it. Everything else was a piece of cake...
About this creation
This collage shows some details like
1 shows the gears that drive the wheels. All four of them have the same formula.
2 shows suspension and the part of the pneumatic piston that opens the doors.
3 shows the front side and a part of the chain. Now the chain is used here to connect the steering mechanism of the wheels and a steering wheel in the cockpit. Yap, they are connected. I had to use the chain since the whole body is swaying on suspension so it had to be a mechanism that is mobile that way.
4. Front lights are LED. Yap, powered by battery box in the back.
more views including the top view
showing the bottom and the mechanism that drives this thing. " big RC driven motors and one medium sized in the back of the cockpit (not visible)
In order to open the doors you have to lift/turn the backside mask with the lights to reveal the pump. Lever that directs the closing or opening the doors is right at the end of them behind the seats.
some details of an interior. You can see the all the seats. There is also a lever that directs the opening or closing of the doors and in the middle there is a switch for the front lights
Finally, here is the matrix for the custom made glass for the cockpit. It is made out of transparent plastic sheets. Second pic is the detailed view of the steering mechanism. It can't be seen but between the two big cog wheels there is a worm gear connected to the electric motor at the end of it.
Thanx for the comments, guys. As for the wheels I don't think they are too small. I don't like wheels to be too big. This way they are elegant, yet a bit monstrous. Anyways at the time I didn't have any bigger even if I wanted to so there :))
Whoa. Technically this is a masterpiece; achiving true 4x4 control!
I dont own any power-functions or pneumatic systems, so can only guess about how it works.
I like the detail about using normal minifig windshield as headlights... ;-)
Only drawback (IMHO); wheels might be too small, -but that doesnt lower the 5/5 rating.
Happy to see you back on screen!
