Posted July 9, 201113 yr On his website, Nico71 recently posted his Lego Technic Pneumatic Vehicle, complete with photo-sequence Building Instructions. He wrote that it "Features drive by a single cylinder engine, clutch, steering and front suspension. This MOC was designed to be shown at Fana’briques 2011, the most important Lego exhibition in France. The aim was to built a “kinematic” MOC in order to have parts in motion. The other aim was to have visible gears to get a more attractive vehicle. Consequently, the MOC is powered by a single pneumatic cylinder engine which provides 1 watt of power (at 3 bars of pressure). The basic principle is based on old steam vehicles or tractors. Then, a remoted clutch by a small cylinder provides the power on the rear wheel (with the main chain). The steering is operated by the steering wheel in the cab with a 8t/screw and lever system (through the chassis). The front suspension is made with a flex part on a live axle. Finally I have had details like the centrifugal governor or the tank (which hides the Air-tank). "Concerning the driving, a hand pump with 4 pumps gives power to the engine. The engine runs smoothly thanks to the inertia wheel. The engine is quite reliable, during 3 days of exhibition, the engine have run without problem. Through this MOC, I think the LPE [Lego Pneumatic Engine] MOC is a good example for a demonstration of what it is possible to do in Lego (such as in an exhibition). Also, I have created the building instructions as a photo sequence included a picture to see the whole parts." [scroll to the bottom of his webpage to see them.]
July 9, 201113 yr Oh man, this is awesome! I love all the moving mechanical bits. The governor is a nice touch as well. Great job!
July 10, 201113 yr Very nicely done, i like the handpump. i guess you placed the Pneumatic Airtank in the front ? [EDIT] After checking out the building instructions i guessed right [/EDIT] Edited July 10, 201113 yr by P4trickvH
July 11, 201113 yr I am happy that you like. The main aim of this moc was to have a nice and moved displayed moc at Fana'briques. People like when something moves on the table during the exhibition (better than static moc). :) In this way, I have also displayed my cuckoo clock and centrifugal tachometer.
