Saberwing40k Posted May 30, 2012 Posted May 30, 2012 Prepare to be amazed, by the Amazing MBMC137! I've been a fan of his work for a long time, and noticed that he had a lot of projects on Brickshelf. Since he's new, I decide to help him out. To get it all off the ground, we start with a Zil-136 Trial Truck. It has 3 Xl motors for propulsion, and 1m for steering. Something to note is that it actually does not have an onboard battery box, or receivers. This is somewhat odd, but not totally without precedent, as IR reception outdoors is terrible. In addition, the weight is fairly low, only 2050 grams. The underside, showing the stunningly simple drivetrain. Unlike most 6x6 trucks I've seen, this one links both the front and rear axles, so as the front left wheel rises, the rear left wheels go down. though this is not shown, this should allow for amazing suspension travel. That is why there are two old turntables on the rear axle. The original truck And a short vid. just look at all the snow on those tires. Anyway, We'll be tag teaming, with MBMC posting new stuff, and me posting old trial trucks. Oh, and I may be posting resized images later, if asked. Quote
Tamas Juhasz Posted May 30, 2012 Posted May 30, 2012 (edited) Thanks for the post! This was my first 6x6 TT in large size. Folder: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=459855 Was built in January 2011 for the first Malug winter TT race( http://www.brickshelf.com/cgi-bin/gallery.cgi?f=460504 ) The rules permitted the PP wheels(even recommended), I think that's the only usable wheel for snow. The Zil worked good, one accident was with the steering mechanism, but in the end became second: http://www.brickshelf.com/cgi-bin/gallery.cgi?i=4867779 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=4867829 The suspenson is a special one, the rear unit with the sideways pendular suspension is linked together with the front axle. The links and the linking method is normal, like in 4x4 trucks. This machine is very good to build because the wheelbases are the same, so the weight distribution is easy to build ideal. There is only one picture about the original, so I had to imagine the rear of the body. Someone asked in YT how are the motors insulated. With the 1x1 round plates(see above). The motors are also the snow remover from the rear wheels(and this generates cooling for them ). The wires are necessary of the following reason: the rules allowed one motor/850 g. So this truck should be at least 2550g to have 3 motors. This construction with the heavy PP wheels weights in this status 2670g. It's already more than the minimum(which is optimal in a competition), and the RC Unit(PF isn't good in outdoor use) would add more 300-400g. It's big, but there isn't much space inside. And the main reason as the colleague wrote: "IR reception outdoors is terrible" Main parameters: Weight: 2670g Pieces: 1431 Top speed: 0,68 km/h Length: 472 mm Width: 250 mm Height: 230 mm Edited May 30, 2012 by Mbmc Quote
timslegos Posted May 30, 2012 Posted May 30, 2012 A great looking MOC. The xl's could have been better placed though. tim Quote
Alasdair Ryan Posted May 31, 2012 Posted May 31, 2012 One thing I am amazed at is that some one else has forgotton the picture size limits here on Eurobrick's which are 600x800. But anyway nice moc's,I bet you can have some fun with them outside. Quote
Milan Posted May 31, 2012 Posted May 31, 2012 A great looking MOC. The xl's could have been better placed though. tim I think they are placed very well. Quote
timslegos Posted May 31, 2012 Posted May 31, 2012 I think they are placed very well. Hanging off the side of the rear axles? i am surprised that they didn't get water-logged... tim Quote
Alasdair Ryan Posted May 31, 2012 Posted May 31, 2012 Hanging off the side of the rear axles? i am surprised that they didn't get water-logged... I am such a big girl..........but i like it. tim That depends on how good the driver is. Quote
Tamas Juhasz Posted May 31, 2012 Posted May 31, 2012 Thanks! A great looking MOC. The xl's could have been better placed though. Hanging off the side of the rear axles? i am surprised that they didn't get water-logged... tim Watch the video, that shows there wasn't any problem with the position. A good TT uses the minimum gears what is possible. This placing allows to have only 3 gears in the rear axles. This way the efficiency can be higher. Not a good quality video, but this shows what it can do: Find an another TT which can do the same.. I wrote the reason, why the XLs didn't get water-logged: with the 1x1 round plates the motors were insulated. The whole machine was designed for snow. Quote
