Posted March 21, 201311 yr Hello! In January 2013 I built this ~ 1:16 Peterbilt 379. The truck is 540 mm long, weights 2185 g (with trailer: 3413 g). The trailer is 690 mm long. http://www.brickshelf.com/cgi-bin/gallery.cgi?f=524252 Functions: remote controlled driving, steering, gear change(1 - 4), turn signals. The truck has a classic ladder chassis, rigid enough to pick it up by holding in the middle with one hand. It was very important to me to be realistic, every axle has leaf springs - a single axle is used as spring: In the rear axles, the suspension is rigid and strong enough to hold and drive with a 2 kg weight. Besides the leaf springs, the rear axles have links, they can equalize in light terrain. There is two XL motor at the front of the drivetrain, with separate IR receiver for more power(I don't have V2 yet). On Xl motor is under the hood, another one in is in the sleeping cabin. Then we can see the four speed gearbox: http://www.eurobricks.com/forum/index.php?showtopic=77000#entry1458898 . With this you can change gear fully comfortable. After the gearbox there is a spline shaft: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=505117 . Inside there isn't a lot of space, and it's full with PF components. One AA battery box, 2 XL motor, 5M motor, 4 IR receiver, 3 PF switch, 3 PF led, an some converter cable are built in. I put a black sticker near to the windscreen to cover them(the Peterbilt logo is my own "painting"): The turn signals also work, with two leds on each side(in the rear bumper and on the cabin door). In the video below you can see it. The working method is simple: one M motor turns a white 24z gear, which enables the led to light with the PF switch. You can adjust very precisely the limit state with the 3L bley axle: It took me for a while to find out, because I need a small turning light operator which fits in the sleeping cabin, where was a very limited space after the gearbox and other parts. The front lights are also working. Everything can be opened(video: from 2:58). Ok, the mudguards aren't together with the bonnet, but I can't do it other. I built in some engine imitation(I know, the real one has different - L6 -, but this can be ~ a V8): It's a trailer truck with this trailer: This one also has an Ir receiver, so the coupling can be full remotely. The support legs can lower/rise the trailer: The suspnesion is adjustable on both axles. The video shows it well from 4:20. You can put even 5 kg of load over the axles. The truck's rear axles also can hol 2 kg, so the total load can be maximum 7 kg. With this, the camion's total wight is more than 10 kg. With this load, it can go in every gear, but it's in 4th of course very weak. In second gear it performs quite well, 0,27 km/h(with 7kg load). Of course, with the full load it can go only on relatively flat surface. The adjustment of suspension can be done with these racks: http://www.brickshelf.com/gallery/mbmc137/92--Peterbilt379/049.jpg Without load and trailer, maximum speed is 1,1 km/h, with trailer and 2 kg load is 0,5 km/h in fourth gear. The video: Hope you like it.
March 21, 201311 yr An awesome model! I think it was on thelegocarblog earlier too (Brickshelf?) Edited March 21, 201311 yr by Ape Fight
March 21, 201311 yr That is a nice looking truck, good functionality as well. The only thing I would change is the yellow color . tim
March 22, 201311 yr Love it, super!!!! can you show us how gearbox works? Edited March 22, 201311 yr by rm8
March 22, 201311 yr Author Thanks guys. Please explain the leaf spring suspension. Thanks. It works with technic axles. One 12L axle is enough long to be good for leaf spring. The front axle is connected to the leaf spring axles, and it's stabilized longitudinal with the 9L black links: http://www.brickshel...y.cgi?i=5792393 - the front leaf springs aren't 12L axles, but made with 10 and 8L axles, connected together with an axle connector. The axles can work as leaf springs, because they can deform, if you want a stronger "spring", you should use shorter axles(rear suspension). Love it, super!!!!can you show us how gearbox works? It's in the description. This topic is about the gearbox: http://www.eurobrick...00#entry1458898 BUT: the controller became more comfortable, you need only two IR remote controller for the 4 speed: http://www.brickshel...y.cgi?i=5742902 Two gearbox are combined, here can be seen the second with the synchronous ring: http://www.brickshel...y.cgi?i=5792390 In the video of this truck you can see the controller and the truck together during gear changes.

March 22, 201311 yr Author Can you make a picture that shows the way rear axles are attached? http://www.brickshelf.com/gallery/mbmc137/pictures-videos/peterbilt-rear-axle.jpg I think it clears the attachment, under the two 7L thin liftarms there is also this piece: The 4 more of this piece in the leaf springs are built in for stabilizing in lateral direction. The rear axles with the central attachment can behave like this: http://www.brickshelf.com/cgi-bin/gallery.cgi?i=4725034
March 22, 201311 yr Good work, love the functionality. This being a Peterbilt my only vice is the frontfenders not going with the hood.
March 22, 201311 yr Beautifull! I was just watching Ice Road Truckers and thought about one of those trucks. I hope to make one some day. Keep on trucking. H
March 23, 201311 yr Very very nice! All these functions and still the looks! Also quite some new techniques, which is always good :) Great work! :thumbup:
