Based on a truck called the Albatross from the game Mudrunner Expeditions, I made this MOC: The truck in the game: It has the following functions: - 6WD powered by 2 PU XL-motors - Front and rear axle steering powered by a PU L-motor. - V8 fake engine. - Winch at the front and rear of the truck, powered by a L-motor and through a little gearbox you can select if you want to power the rear or the front one. - Independant suspension. A video of the model: A few more photo's: The "fuelcap" (the black ball) on top of the "fueltank" turns on the hub. The bionicle tooth you see below the bed at the rear is the gearbox switch for the winch. Technic fig compatible I am really pleased with how the suspension works. The first 2 axle have 1 hard spring per wheel, the rear axle has 2 hard springs per wheel, because of the hub in front of that axle and the overhang at the rear that houses the motor for the winch (and with this setup it can actually carry a load of cargo too ) To remove the batteries I have to remove 2 liftarms and a part of the drive axle, which I build so it can be easily removed by me. A few things I didn't manage to do, but wanted to are stuff like a 2-speed gearbox and diff locks. but I simply could not make them fit while keeping the functions that did make it into the model. I wanted to keep the central column of the chassis slim (like the truck in the game) and keep the bed clean for actual cargo, so that put a limit on the space I had available. Diff locks either meant a higher drivetrain (at the cost of the V8 and bed probably) or a wider model (I can't think of a diff lock mechanism that takes less than 7 studs in width). A greater desire to use these parts for the independant suspension combined with the planetary hubs meant it would get 2 studs wider, which felt too wide for this tiresize. I also feel like the front of the cabine should be 1 stud longer forward at the expense of the hood, but I loved this Technic panel on the hood too much to let that go (and the tiles on the sides would be very hard to attach if I put it 1 stud forward, so hard for me that in the current build I stole a stud from the door instead to secure the A-pillars ). Sorry for no video yet, I might make one in a few weeks. The problem is at the moment that I have to use the one thing that could make a video to control the model through the Brickcontroller app Thanks for watching and reading! -
Hi, after finishing my luffing crane I worked on a very compact 6WD truck with skid steering. The digital model was almost finished about two weeks ago. I prepared to order the needed parts - but then I noticed the "BuWizz fast car competition". And I decided to upset the applecart. The original concept did not have any suspension and would not fit the conditions of the contest. So I widened the chassis and integrated independent suspension to all 6 wheels. There are two separate drivetrains for left and right side, each using an L-motor. But the clue is: they are connected by a subtractor powered by an M-motor. You might know this strategy from my previous MOC "Woody and the Woodpicker" https://www.eurobricks.com/forum/index.php?/forums/topic/156214-moc-mini-skidder-woody-and-the-woodpicker/&tab=comments#comment-2880712 But there are little differences to "Woody". The drivetrains are geared up to make the vehicle much faster (as it is a fast car contest ...). On the other hand the subtractor is geared down to make steering smooth at high speed. Enough words, here it is: About 1 week to the deadline ... I hope the weather will be fine next week to make some outdoor videos Regards Leonard Goldstein
