BB-8 Posted November 3, 2015 Posted November 3, 2015 (edited) Are these Ansmann tires? Do you have detailed pics of the planetary, or an lxf? Did you use these u-joints in the front axle (http://www.shapeways.com/product/BNMKB2M9A/u-joint-with-gear-8z?li=user-profile&optionId=57250990) Edited November 3, 2015 by BB-8 Quote
efferman Posted November 3, 2015 Author Posted November 3, 2015 The planetary gear is the same like in this axle. Yes thesse are the u joints i have used, And yes these are my ansmann tires. Quote
MaxSupercars Posted November 3, 2015 Posted November 3, 2015 I didn't mean it so that the plastic should be damaged in your model... I meant it so, that if we want to build realistic drivetrains then Lego would must use the metal gears because with plastic we have to do always compromises and make Lego suitable solutions... :) Max...

Zerobricks Posted November 3, 2015 Posted November 3, 2015 Can you show where the skipping ocours? Problem with having 1 driveshaft for 4 axles or 8 wheels is that when one wheel is stuck it has to whitstand the power of what is usualy transfered to 8 wheels... Thats why I prefer using 1/motor per wheel or axle and you also get rid of differentials and get more control. Quote
efferman Posted November 3, 2015 Author Posted November 3, 2015 The diff is in a 5x7 frame and is driven by a 20 tooth double bevel. And this 20 tooth is drven by a 12 tooth double bevel above. These two gears should normaly placed between two triangles, but this is not the case on these axles and under high load they jump over. My last setup was really rocksolid, but the frame was really high and the chassis was zero kat 1, and i want a kat 1 chassis. So i have to use one driveshaft. Quote

Thats why I prefer using 1/motor per wheel or axle and you also get rid of differentials and get more control. On the other side, when you climb on obstacle with 8x8 and first and last axles are in the air the power of 1st and 4th motor goes lost because they are not integrated in common drivetrain... the whole weight of the MOC lays then on 2 middle axles, so there is double load on middle axles and double load on 2 middle motors... So the power gets lost and load increases what causes stucking if you use 1 motor per axle configuration... The biggest advantage is of course minimizing/zeroing of friction losses in drivetrain... Everything got pros and cons... Hmm... Max... Edited November 3, 2015 by MaxSupercars Quote
efferman Posted November 19, 2015 Author Posted November 19, 2015 New parts have arrived the shock absorbers are a hop up set from tamiya for the cr-01 chassis. i expect a much better ground contact with these long travel shock absorbers Quote
2LegoOrNot2Lego... Posted November 20, 2015 Posted November 20, 2015 This is so amazing!!! This is the ultimate axle setup, really love this so much!!! :thumbup: Does this setup allow hub gear reduction? Really wonder what you will build with this, so many options!!! Crawler maybe? Quote
efferman Posted November 20, 2015 Author Posted November 20, 2015 A MAN Kat1 8x8. in meanwhile it is more or less a drivetrain test vehicle Quote
2LegoOrNot2Lego... Posted November 21, 2015 Posted November 21, 2015 A MAN Kat1 8x8. in meanwhile it is more or less a drivetrain test vehicle You know, this axle setup is so realistic!!! You did an excellent job on this one...again...!!! Quote
efferman Posted November 21, 2015 Author Posted November 21, 2015 (edited) Thanks, but with lego it is very experimental. And the planetary rims with the turntables have much friction now. So i have to clean after every run. Edited November 21, 2015 by efferman Quote

efferman Posted December 14, 2015 Author Posted December 14, 2015 a small modification on the lucio switch tractor unit. actuall standing Quote
Zerobricks Posted December 14, 2015 Posted December 14, 2015 Wow, the amount of springs in the front! Are you sure the suspension arms can surive such forces? How are the rear axles made? Pendular? Quote
efferman Posted December 14, 2015 Author Posted December 14, 2015 Like the truck from lucio switch it has a pneumatic suspension on the rear axles. And the frontaxle has 6 springs per wheel too. I have made it simply more solid. Lucios truck is on some points a little bit weak. Quote
efferman Posted December 15, 2015 Author Posted December 15, 2015 i cant decide where the third batterybox is placed. Lucio has placed it in the storage box behind the cab and i want to fit all, which was in this box, at the side of the frame. but at the left or at the right side? lxf Quote
BB-8 Posted December 15, 2015 Posted December 15, 2015 New parts have arrived What are these black discs at the outside of the turntable? Quote
MSc Shobaki Posted December 15, 2015 Posted December 15, 2015 i cant decide where the third batterybox is placed. Lucio has placed it in the storage box behind the cab and i want to fit all, which was in this box, at the side of the frame. but at the left or at the right side? lxf Michael, is this mod compatible with the rest of Lucio's truck? Quote
efferman Posted December 15, 2015 Author Posted December 15, 2015 The cab will fit, but the fifth wheel is one stud higher than lucios truck Quote
MSc Shobaki Posted December 15, 2015 Posted December 15, 2015 The cab will fit, but the fifth wheel is one stud higher than lucios truck What I meant was if for example the cylinders for the cab tilt have the same mounting points as in the original truck by Lucio. In other words, are all the featured functions in Lucio's truck still intact in your mod? :) I'm asking because I like what you have done so far in your mod Quote
efferman Posted December 15, 2015 Author Posted December 15, 2015 Every function will be included. And the cab tilters will have the same mounting points. Quote
