Need Help Making Heavy AWD SUV Move Better
StudRobotics posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I'm back with one last issue in my GX EV3 build. I just got done finishing the doors, side panels, rear trunk door, hood, and some part of the roof. But the vehicle was so heavy that when I drove it around, it kept on doing the same thing. The diffs were clicking and the car had very much difficulty moving. Here is a picture of the bottom of the vehicle. Most of the clicking seems to be coming from the rear diff when I move the wheels by hand. I can either do two things. 1. Reinforce the rear diff somehow. 2. Improve it's off-road performance and stop the clicking somewhat by replacing the diffs with knob gears. But this will come at the cost of independent moving between the wheels. What should I do? Please give me the best response you can so the clicking will stop and I could finally take this AWD machine through some rough terrain like a real SUV. I really appreciate any advice. -
4 Speed Differential gearbox

Hi Everyone! I just created this, and thought I would share, as it might give someone an idea for a us in a Moc or something. I'm thinking a car perhaps with seats on top. It could only be 3 studs high. It basically gears around the stationary motors and I'm guessing creates the following ratios. 1 motor equals 4:1 2 motors equals 2:1 3 motors equals 4:3 And 4 motors equal 1:1 output. Now if you could create a level on the remotes that engages 1 channel at a time, you would have silky smooth gear changes! Sorry if this has been done before!
