Samolot Posted February 18, 2015 Posted February 18, 2015 (edited) Hello this is my first MOC on this forum. This is only my second fully self MOC, so I treated it for training purposes. The assumption is, to put all the mechanisms as tight as possible and connect pneumatic with electrical systems. Another task that I set for myself is a removable body. Body is connected to the chassis on seven accessible pins, also have to disconnect the power to the lighting and pneumatic for lifting door. For some time, i was thinking to create a progressive suspension of lego. Which has two operating ranges. Is sensitive and precise on a level surface. But it works fine even on rough terrain. The combination of spring and pneumatics gave such an effect and it works very good. Most difficulties caused me to prevail over the steering and drive moving at such a high pitch, and quite a bit of weight of the vehicle. I am aware that it is far from perfect, but it works. Description Weight 2 kg 2 x battery PF Drive 4 x PFL 2 compressor pump 6l and motor PFM The steering servo PF Pneumatically adjustable suspension two large cylinders of the engine controlled PFM Airtank The door opened up two small pneumatic actuators (manual) PF 2x LED Lights Automatic low pressure valve actuator and electric switch of the old type. The trunk opened manually. Movie Full Gallery http://www.brickshel...ry.cgi?f=549113 Edited February 23, 2015 by Samolot Quote
Zerobricks Posted February 18, 2015 Posted February 18, 2015 (edited) Amazimg first MOC! I love the fact suspension uses normal springs AND pneumatics. Edited February 18, 2015 by Zblj Quote
Jeroen Ottens Posted February 18, 2015 Posted February 18, 2015 Great Moc You could use bigger photos though, max width is 800 pixels Quote
5imon Posted February 18, 2015 Posted February 18, 2015 Great and unique body design! The front reminds me quite a lot of the Lamborghini LM002 which impressed little me very much, back in the day. Quote
LegoMathijs Posted February 18, 2015 Posted February 18, 2015 Great design! The red/black colour sceme looks very good! Quote
Graydingo Posted February 18, 2015 Posted February 18, 2015 Awesome! having just built air ride suspension I'm very impressed! Quote
Paul Boratko Posted February 18, 2015 Posted February 18, 2015 Smooth looking model you got there.. :thumbup: Quote
z3_2drive Posted February 18, 2015 Posted February 18, 2015 Great MOC, especially as a first. When I first saw this it reminded me of the Dejong MXR buggy: Quote

VKTechnic Posted February 19, 2015 Posted February 19, 2015 Man, that bodywork is top notch. Captured that Dakar stance very well Quote
darsedz Posted February 19, 2015 Posted February 19, 2015 great design, nice suspension... body in blue will be closer to Renault Schlesser Quote
KirTech LAB Posted February 19, 2015 Posted February 19, 2015 (edited) Very nice car!!! Can you add movie with extended test-drive? :) Edited February 19, 2015 by desert752 Quote
nicjasno Posted February 19, 2015 Posted February 19, 2015 (edited) Your steering rods need to be paralel to the suspension arms, not straight like they are now. The amount of bump steer this generates must be enormous. edit: i see that is the rer of the car i was looking at, but i still don't get why you have the 9L steering links there, since it doesn't look to be a multilink setup.

Samolot Posted February 19, 2015 Author Posted February 19, 2015 Links at the back of the car are to stiffen the rear suspension. The car has 4 PFL motors to drive and there is no central diverential .Suspension also has a long operating range and those links have solved the problem Quote

What do you mean? How does this change bump steer? Quote
Samolot Posted February 23, 2015 Author Posted February 23, 2015 Video showing the performance of the air suspension Quote
Rockbrick Posted February 23, 2015 Posted February 23, 2015 (edited) Technically its not airsuspension - its pneumatic height control - the suspension is still springs.... IMHO the only model to have a proper implementation of airsuspension (with automatic height control and air brakes to boot...) is sheepo's legendary Peterbilt truck: http://www.sheepo.es...79-cat-c15.html Excellent model though sorry didnt meant to sound too negative!

MacKaiwer Posted February 23, 2015 Posted February 23, 2015 Nice, nice, nice Like it very much. Cool looks and cool ride height adjust system! Unique looks but maybe little bit like this: Quote
