I got this idea a while ago, when I first got Sbricks. Why not make modular, expendable system of axles and chassis pieces in order to create a system for offroad truck construction. Here is what I sketched up in LDD. First we have a basic axle. It uses 2 XL motors for drive, independet suspension and steering with servo Because we need a minimum of 2 axles, I designed a double chassis holder with two battery boxes: If we combine 2 axles with the double battery holder, we get the most basic configuration, a 4x4x4: In order to expand on the system I designed a single battery chassis extension: Finally we can combine the three basic modules into a 6x6x6: Or even a 10x10x10: In theory there is no limit how far you can go, but I think anything over 12x12 might cause too much strain on the chassis. Important details: - Axles are designed for Claas wheels, which are not in LDD, hence the wheels above may look small - Each axle can use any kind of a combiantion of number of springs and hardnesses for best flexibility and weight support - Each axle is meant to also house and S brick, which allows you fine steering angle control in order to support any kind of configuration or steering mode (only front, only rear, all wheel steering, crab mode) - For now this is still a concept, so I will relase the LDD file once I build, test and polish the concept -
Presenting the 8258-B Crawler, Designed and built as an entry for the 'Crawlify your set' contest [AMS1] I'm a huge fan of b-models in general, but the 8258-B has always been one of my favourites due to great looks and an easy to modify. Or so I thought... In the end, I reckon about 85% of the chassis has been custom built. There are two L motors situated just below the cabin. One powers the front axle, one powers the rear. Both axles have differentials because, being independently powered, loss of traction is a lot less likely and it saves my poor pieces from becoming mangled. Because the 8258-B is rather small (read: narrow) I had a lot of trouble designing a front axle that could house a servo motor without limiting the range of suspension travel. Eventually I gave up and ended up modifying this axle to accommodate a differential (well deserved credit to the amazing @Madoca 1977). However with that said, I have made sure the bodywork stays almost 100% true to the original. The only alteration I had to made was to the rear wheelarches to make room for the balloon tyres: Original wheelarch Modified wheelarch: Also, the front winch kept scraping on obstacles I was trying to climb over so I switched this out for a bullbar, however the two are easily interchangeable. Anyways, here's a video of this thing in action. As always, please let me know what you think. Whether it's praise, criticism or telling me off for building ANOTHER red and black model (I have other colours, I swear!!), I'd love to hear it. More images can be found in this bricksafe folder. Enjoy =) -
Hi everybody! Today I present to you my first experience of construction Trial Truck! During this year I was looking for your ideal 4x4 chassis. And in the end I came to this building. In the final, which turned this freak on 4 wheels medium size range (80-82 mm). The main idea of this project was the task of the displacement of the center of gravity down and forward is not at the expense of detail, as well as the compulsory use of the portal gears on both axes for high permeability and stability of large CG. The power installation in the form of two twin L motors located in the rear axle, where through the reduction gear torque is distributed to the axle gears back and forth, and then the rotation of spreads on all wheels through a gantry gearboxes. This arrangement limits the transverse rear axle moves up one degree of freedom. Yes, the rear wheels are posted on the obstacles, but discomfort on the track it does not deliver. Servo motor for steering is mounted on the front axle, which also lowers the CG and the sprung mass model. Power - LiPo, management - Sbrick. Number of pieces - 875 pieces Weight - 950 grams More photos you can find on my flickr and blog -
Hello Community Today i started a BIG Project. I´ll try to build it as near as possible to the original. Thanks to IVECO they show the details of this truck on their Webpage. (I found it only in german) Functions planned: AWD Pendular Suspension It has leafsprings in real life. I know leafsprings are possible. But not in my scale i believe... But i´ll try When i can´t reaplicate them i will use springs instead 3. Because my last big project failed because of the weight (and broken universal Joints ) i will build in only 1 BB, 2XL, 1 Servo Tires: I think these tires look great and fit the tireprofile realy well. Wheelhubs: I made some heavyduty Wheelhubs for my truck. LXF Updates coming soon. Improvements, Suggestions and Critic are welcome! -
Hi all! Some days ago, there was a little talk about an international Truck Trial race in Zblj's topic. So, the competition happened, it was a great time, to meet each other again (most of us were in the first international TT meeting, in Keszthely, 2011). It was a bit of special event. The idea came from Mihai Dreve (Braker23 here), He planned a trip to Hungary, and asked us about a TT race. Then Zblj joined us, and became an international event with 3 countries: Romania, Slovenia, Hungary. I'll be advertise here, if there will be another international TT meeting, organized by us (Hungarian Lego Truck Trial Club / Malug). This was the third international Truck Trial themed meeting in Hungary, in 7th of May, 2016. The location was the edge of Budapest, the Harmashatarhegy. It's our usual and most used place for TT, has many advantage, like large area, large variety of terrain, hills, stones, logs, etc. Generally, our TT club is mostly private, it's a closed discussion (rules, location, day) usually, and we only publicize the advertisement (with final rules, etc.) of the race. We know about the possible participants, they are in the discussion. Luckily, Agrof, and Lipko could also join us, so this event became a little Eurobricks meeting, too. Special thanks to Agrof for the awesome first prize! Can be seen at 18:21 in the video below. Thank you, Peter! I put every important information, moments, good photos, shots, trucks, builders, results, and as many fun, as I found - in this video: Watch in 1080p, with fullscreen: Hope you will enjoy the video. More pictures, galleries will arrive soon, I'll put them here. I made another version of the video, with the original sounds, if someone needs, ask me in pm, and I'll send the dropbox link. Comments, questions always welcomed. -
Hi! A few weeks ago I started doing some prototypes on a tracked trial vehicle. It will probably have 2 long tracks with pins in them, skid steering using 2 L or XL motors and one BB. Goals: find a soft and smooth suspension, have a bodywork wich looks kinda like a ripsaw(not EV2), be able to climb some not really steep hills and descend them as well, float on/over the snow. Acheived goals: find a soft and smooth suspension, I will come back with some photos of a smaller prototype to get the idea. -
4 years since my last tatra and a few months since I don´t build for myself so I started with something simple, a 4x4 tatra. My goals are simple, fun, easy to build and robust. The steering in tatras is the funny part to do because is almost impossible to make it perfect, mine it was... but with inverted ackerman steering , I can do three things to solve it, leave it this way because it will work, turn the steering but the chassis will be less simple or use the steering I used in my old tatras. The suspension uses rubber bricks and I don´t know yet what motor I will use and neither the look, tatra dakar or t815?.

Good day. This is a trial truck using 1 XL motor for drive, 1 M motor for steering and powered by BuWizz. The drive is powered through a worm gear to 8t gear, creating a powerful 1:8 reduction. It uses model team wheels , they don't have the best perfomance, but it is good enough. For the bodywork I was inspired by ГАЗ-66 (gaz-66), although it isn't an exact copy. Both doors can be opened, the seats and steering wheel are adjustable LDD model available here: download -
Howdy folks! Now this one has been a very fun build for me, as I never attempted to build a vehicle inspired by the Mad Max movie series, although I always wanted to. This was also a hell of an opportunity to use many of the odd parts that you simply cannot put on a normal vehicle, so I am thrilled to present to you, the frightening Gator Mayhem! As you can see, it's and odd blend between and alligator and a trial truck, thus it has 2 animal-specific functions (biting and hitting with the tail), 2 car-specific functions (driving and steering) and of course, 2 tank-specific functions (rotating and firing the turret). What I can tell you is that my two boys just love to play with it, shoot minifigures and eat them all, so I suppose my goal was reached. Functions-wise, I think it's pretty packed, as I managed to squeeze 6 motorized functions, a working V24 fake engine (two connected V12, placed diagonally), working steering wheel and fully openable doors, so you can exit the truck in a flash. This MOC took around 3 weeks to build, almost every day for 2-3 hours, so I can assure you that my dedication has grown a lot, but my wife's patience also reached a new level Technical specs & functions: - 4x4 Drive (XL motor) - Steering (L motor) - Open/close gator mouth (M motor) - Swipe gator tail left/right (M motor) - Rotating turret (M motor) - Firing the turret (M motor) - Turret capacity: 5 missiles - controlled by: 2 BuWizz bricks - a functional V24 fake engine - working steering wheel - openable doors - Length: 72 cm - Width: 30 cm - Height: 30 cm - Weight: 2.8 kg Official YouTube video, made for the [TC17] competition: First batch of photos I took in my kitchen/studio, enjoy the show! Second batch of photos were taken outside, in the most post-apocalyptic environment I could find nearby: As usual, for more detailed photos and many others, please check my Flickr album, below: https://www.flickr.com/photos/braker23/albums/72157713228122532/ Cheers and best of luck to all competitors! -
As suggested by Jorgeopesi in this thread use this thread to post all trial trucks together for new people coming into Technic. Please post the year of completion, and a reference url. I'll get us started. My Kenworth T55, built in 2012. And my Mack Marble 5T, also built in 2012. -
Hey everyone, I've been working on this trial truck for 2 and 1/2 weeks now, and I am nearing completion. At first I wasn't going to make a WIP topic, but I need some advice for the cab design. So this is what I've been modeling mine after. My problem is the V8 engine, because the engine is too far back I had to make the cab longer as well. This totally throws off the proportions and makes the wheels look to small and the chassis too short. I also thought I would be able to make the cab in the new green and I have enough of the panels, but not enough liftarms. So I am open to color scheme suggestions. Just to let you know though, I could probably do it in Black, Red, Yellow, and possibly White with Blue. Here's what I have so far: As you can see I also have to accommodate for a tilting cab. It has full live axle suspension and an XL motor for drive and a Servo motor for steering. -
Hey Guys, So I decided to go back to one of my first MOCs and wanted to rebuild the whole thing. Going with live axles, XL motor mounted directly to it, then geared down to 1:3 and have the knob gears to finally deliver the power to the wheels. I will probably do the front end tomorrow. So what do you guys think? Too overkill? :P And this is V1 -
Hey everyone! I have started tinkering in LDD on my next project. Here are some photos This is the first time I have built anything this large so we will see how it goes. I plan on using 2-4 xl motors for drive and will have an m on steering and another on a gearbox/winch. I think I will build a similar chassis to that of Sheepo's Defender as it is pretty sturdy. Anyway I will report back soon. (I have attached the .lxf if anyone wants it) 8X8.lxf -
Hi! This is a new chassis I have built, it features: 8 wheel drive by an XL motor 4 wheel steering by an M motor 4 live axles I willl put a winch on it still (any other ideas?). The performance of this thing impressed me a little, because I have only seen 8x8s with 2 XLs or more, so I wasn't sure if it would have enough power. The body will be of the russian Kamaz 6450 truck. I will make an LDD file of this too.

Hello! I recently ordered some new tires from bricklink and wanted to make a truck to test them. I originally wanted to do a Man Kat1, but decided to do something smaller, so I tried to replicate a MAZ 535: The real one has independent suspension (mine has live axles), so it is not very accurate, also the wheelbase is about 1 stud too long between the 1st and 2nd axles. This truck features: 4 live axles with "leaf springs" 8wd with an L motor 4 wheel steering with an M motor The steering is a little sloppy (2nd axle) but it's still very enjoyable to drive. I love these tires, they are super grippy and have a deep tread, much better for offroad than the newer ones: -
-4x4 -Live axles with panhard rods -M motor for steering -L motor for drive (geared 1/5) I wanted to build a truck, that would be as light as possible, but a full pickup body would have weighed it down (I have tried it). So I built half of a pickup without doors, which works very well. I originally wanted to use the smaller tires, but now in winter it performs much better in the snow with the balloon tires. What do you think that looks better? Inspiration:

Hello! I have built yet another mini trial truck, this time I tried to replicate the Russian Gaz 66 off road truck: To use the model team tires I had to make it very compact, and as a result I had to use a chain to transfer power to the driveshaft, which I do not like. I used leaf springs (flex axles) in my live axles, which both makes it very compact and gives it tons of suspension flex. 4x4 - M motor Steering - M motor Leaf spring live axles Video:

After building the Gaz 66 truck, I went for a slightly longer truck, an 8x8. I tried to replicate the Finnish military truck Sisu E11T just because the wheelbase is long enough, the bodywork is definitely not very accurate though. The length of the u-joints would make it very hard to make it shorter with this design. Axles 1 and 2 are pretty much the same as the front axle of the Gaz, but this one uses 4 19L flex axles for leaf springs, because 8 shorter flex axles would not fit. Features 8wd with 1 L motor 4 wheel steering with an M motor 4 leaf sprung live axles Video: Suspension test: LDD file: https://drive.google.com/file/d/0B3uQRNR6UbBWeU5tc0lDU2ZGQTQ/view?usp=sharing

Hi guys! I am new here so I wanted to show you my trial truck! http://nxt45.files.wordpress.com/2013/11/img_0705.jpg Full description & YouTube video on my blog: http://nxt45.wordpre...go-trial-truck/ (how do you post YouTube videos?) As always Happy building! NXT45 -
Hello! This moc was made a while ago (last year), but I realized, there is no topic about it yet. I wanted to make a heavy and fast trial truck from Zis e134. Original model: My version: folder: http://www.brickshel...ry.cgi?f=496827 Basically, it was built for truck trial race, so it has a "propulsion motor/weight" ratio, each RC buggy motor carries ~ 1 kg. There are 4 buggy motor built in, each axle has one. Only two gearings (40:8 and after that a 24:8 reduction) are in the drivetrain in each axle, so I hadn't problems with efficiency. Total wieght became 4190 g. I used 1957 parts to build it. It's my longest and heaviest trial truck yet, total length is 610 mm (width: 283 mm). The 4 motors give enough power to reach 1,7 km/h top speed (flat surface), I used two RC units to power them. I think the most important part in these 8x8 trucks is the suspension. I tried to make a long travel one, which allows the wheels to make contact with the ground in extreme terrain also. The rear axles are built in a unit, which has a linkage (see pictures). This unit can bend also, but not sideways. The two front axles can bend sideways, and lenghtwise also. So without springs, the suspension does it's job: The second and third axle are connected together with these bars. They seems weak to here, but I can say, there weren't problems with those during the tests and races. They don't hold the axles, only make positioning, but of course, some force can be appear: Bottom: I made some details, like net in the driver's door, flags, grilles to the front: This truck was able to drive in heavy snow.

Hi! Since I started to play Spintires I have wanted to build the Ural 4320 truck. I just added an extra axle to my mini rock crawler (http://www.eurobricks.com/forum/index.php?showtopic=107051&hl=), to make it fit the proportions almost perfectly. I haven't started building the body yet, which I may need some help with

Hi all! In June 2014 we made a little trip to test an off road RC track, thanks for it to the Home-Road R/C Team. It wasn't a race, just a test. Pictures can be found here: https://www.dropbox....palya-teszt.rar Video: download link: https://www.dropbox....t-kis-meret.mp4 I recommend the end part from 28:00 to 29:00, some interesting and funny moments can be seen. We used two crawlers, a 6x6 test chassis, and two trial trucks. I hope we can use the track in the future, a cooperation with the RC team is in process. If we had more time, the video would be better, but because it was together with the RC team, we had limited time before their race. The main test vehicle was a crawler, has also topic here: http://www.eurobrick...showtopic=97878 Hope you like it. Feel free to ask or comment.

I have a small question to ask yourself: do you know sites that sell lego technic metal gears? I've had enough need since my Tatra truck has already broken two in half .. the problem is that I do not notice when they break because it happens suddenly. I realize after several minutes that lacks a gear since my truck is powerful enough to continue to advance with little difficulty. I hope that has not already been made any discussion of this topic.
