Reversal transfer case Has anyone tried one of these? In theory, it should eliminate torque twist by counter rotating the drive shafts. https://uploads.tapatalk-cdn.com/201...76aae0bfe4.jpg Sent from my SM-N910P using Tapatalk |
Re: Reversal transfer case Maybe you could save yourself sixty bucks and flip it at the diffs? (I think that might have a different effect though.) Sent from my Nexus 5 using Tapatalk |
Re: Reversal transfer case Would it reduce torque twist if you used 2 different stiffness on the rear springs? Sent from my Nexus 6 using Tapatalk |
Re: Reversal transfer case That's interesting. Good find. Sent from my SM-N910V using Tapatalk |
Re: Reversal transfer case So instead of lifting the front wheel, it grinds it into the ground? I guess you can get the power to down that way. Still doesn't get rid of torque twist so to speak. Price doesn't seem bad for a complete aluminum piece if it actually works. 4 wheel indy= no twist. :mrgreen::mrgreen: It will be very, very interesting to see if the scale Trophy Truck crowd jumps on board with this product. |
Re: Reversal transfer case If you have a drive shaft connected to an independent drive line, you will have torque twist. If you spin it the other way it will twist the other way. Corvettes have a tube that connects the trans to the diffrential and makes it one solid piece. Take a rear axle from an rc car. Lock the tires from spinning to replicate load. Hook up the axle to a t-case with drive shaft. Now hold the t-case in one hand and turn the input shaft. No matter which way you spin it the same thing will always happen(you may need to put something on the input to get enough torque). When you have two disconnected bodies transmitting load they will always try to spin in the opposite direction. The motor only provides the torque but does not do any frame twisting as it is solidly mounted to the trans, and t-case. Always twisting against each other, however the case itself acts to hold. All the twisting force and thus transmits no forces to the chassis. Only two ways to combat twist. One is lower gearing. It takes less torque to move the vehicle. And two solid mount your driveline to itself. Ever see torque twist on an moa crawler? Sorry for the drawn out response. I spend way to much time thinking sometimes.

Re: Reversal transfer case Well I responded without actually reading the post, lesson learned. This is actually something new. My thought is though that all the above still applies. The only time this will make a difference is when front and back wheels are loaded the same. But instead of twisting it may just pop the chassis up to full droop. But in most circumstances you will only be loading up the rear end. Sent from my SM-N920P using Tapatalk |

BTW, why would you buy this T-case when you can accomplish exactly the same thing by reversing your motor leads? Sent from my Nexus 5 using Tapatalk |

Re: Reversal transfer case What shawns is saying is that the front rotates the opposite of the rear. Its probably got a planetary gear in the front output to reverse it. Sent from my SM-N920P using Tapatalk |

Re: Reversal transfer case The only way to eliminate torque twist is to have the motors output(transfer case/center diff/pinion spur)and rear diff solid mounted. Think independent rear suspension(buggy, truggy, monster truck, CHASSIS PLATE).. as soon as you have a solid rear axle you introduce twist. Twist is an effect of haveing suspension between 1 item twisting another. Only way to eliminate torque twist on a bomber is to message the DMG, and order a B2b |

Wouldn't a Bomber be awesome with some Berg axles? :mrgreen: |

Re: Reversal transfer case I'm just gonna leave these here. They helped me a lot and were pretty good reads. Basically what lanky said. Any time the diff isn't connected to the frame, you're gonna have twist. Same goes for front and rear. http://www.rccrawler.com/forum/axial-ax-10-scorpion/367502-what-torque-twist-tt-how-fix.html http://www.rccrawler.com/forum/general-crawlers/54791-anti-squat-suspension-tech.html |
