  1. Hi. I was working on my car MOC (with a four-speed gearbox designed by Sariel) and had some unfortunate events happen. As stated in the title, the differential is somehow making the gear ratio higher than I need it. The gear moving the diff is moving at the same speed as the power input, but the wheel hub moves one rotation for every 3/4 rotation that I move the input shaft. Is this differential piece supposed to do this? I want the wheels to move at the same speed as the motor at 4th gear, which brings me to my next problem. I hear rapid-fire clicking noises every time my car is in 3rd and 4th gear. This happened to my other MOCs too, but I was able to solve it. Since the car is to be powered by two EV3 large motors, I actually believe there might be a clutch mechanism in the motors such as in the Technic linear actuators that also make a terrible clicking sound when they move all the way up or down. Whatever it is, I'm open to responses and hope the Eurobricks community could provide an explanation and solution about both of these issues. Here's some pictures, the orange and red pieces in the first pic were for testing the rotations. ' Thank you for your time.
  2. Hi I am working on gear pairs meshed directly together, in a 2 by 2 arrangement. Two gears on each of the two axles - However one gear is an idler gear which is driven by the other gears instead of with the same rotation speed as the motor. However I'm not sure if the ratio for the idler gear will be 1:1 since there is two 16 tooth gear gears in either example I don't think it is 1:1 though it should be what the other two gears are, so say 3:1 or 1.6:1 but I'm unsure as it's hard to tell. The yellow axle joiner goes to the motor, I'm using a differential to replicate a single 24 tooth idler in the first image. Obviously the dark grey gears are the idlers. Any ideas what it could be. More gears can be used with studed beams and plates such as 16 tooth +12 tooth or 20 + 20 or 16 + 20 etc. Regards, S
