Modular trial truck chassis idea
Zerobricks posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
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
