the differential used in its most common application is used because the wheels are allowed to turn at different speeds.

Hey guys, I was thinking today the different uses of the differential gear. I dont know why, i just thought of it. I can only think of it being used for a drive train, whether it is in a gearbox or used as a differential. Im wondering if anyone else has used in it a different application.

We actually discussed this but Efferman didnt join the conversation Maybe he will have some ideas Anyway here is where we were talking about it, starts at post #541 http://www.eurobricks.com/forum/index.php?showtopic=86913&st=525

Good idea

So I got the truck done today. Hooked it up the the load and the wheel slippage has been fixed... but the truck does not have power to pull it. So simple fix, I geared it down for my torque. Ok so now my problem is a high drop in voltage from the 4 XL motors and Servo all in one receiver. Any thoughts??

thanks for all the comments today, they are very helpful!!! I decided to rebuild the truck into an 8x8 anyway, even if it doesn't help me with wheel slippage. Here is the new truck, I didnt get the chance to do wiring an add some detail, but the truck runs very well. The front 2 axles are driven by 2 XL motors and the same goes for the rear 2 axles. Do you see the beams at the level of the axles They have little of a bend in them... haha Didnt break anything today though!!!

Lets say the jeep of the real trailer is the actual trailer and the red boxes are the load. I still have the same problem as if the real part of the trailer is attached to the jeep. I understand what you guys are saying about the distribution of weight to the rear axles, but adding more weight right on the king pin of the trailer still does not do anything to help with the wheel slippage.

Alright so I took some pictures, I was not really sure how to show the issue with a picture, but if a video is needed, i can try it. The two red boxes are about the weight of the load the truck would be carrying. Keep in the mine the jeep/dolly is in the first stages of building, very rough build. I think my first approach to fixing this will be to up the horsepower (add more XL motors) and drive each axle separately. And if that does not work, I will have a set of XL motors drive the front 2 axles and the other set of XL motors drive the rear axles giving me an 8x8 truck.

I dont know about you, but I dont dustmy basement But, yes their is a lot of dust of the floor, but not enough to coat the wheels in a layer of dust

If i video is needed, I can try and take one. I am using the 62.5 tires. I have not done any experimenting with different drive methods, it was late last night when i got a different part of the MOC done. I will be working on modding the truck later to fix this wheel slippage problem The truck im using this is one... http://www.eurobricks.com/forum/index.php?showtopic=120229 EXCEPT, the chassis is a bit shorter. But these pictures should give you guys a good idea of what the truck has to offer.

I'll post some pictures today

I tried just adding battery boxes on the king pin (centered over driven axles) but no difference. I'm driving it on my basement floor, concrete. Would those be wheel slippage if their wasn't enough power? Could the load just be too heavy?

Hey guys, I'm working on a small project just for something to do other than homework all the time. figure I would try and build it. I'll share it once it is completed :) but anyway, it is a semi truck with a heavy load, but the load is quite heavy and I get a lot of wheel slippage on the rear axles (truck is only RWD) I could make I a 8x8 truck but I'd rather fix the problem another way, but I'm not sure how. I will try to make the truck an 8x8 tomorrow, but I'm not sure that will fix my problem. Any thoughts??

You all did a great job!! Here are my votes; 14:10 3:6 7:4 1:3 16:2 5:1

thanks for putting all these box pictures all in one place Emmi. I guess you are looking forward to the Porsche, enough to change your profile pic

You have my vote, very nice build!!

Ya, you are right, I thought they were those form the beginning. More new parts!!! haha

Arent the buckets these?? http://alpha.brickli...page?P=2950#T=C

has anyone come up with LDD files for PTO mods yet

If you want everything in the same scale, I disagree, the Arocs is technically too big. 42035 is a perfect match, those trucks in real life are Giants, just goes to show you how large the BWE really is. IF the BWE was made in Arocs scale, the part count could be easily 4,000,000! EDIT: 4000 wasn't enough, it would have 4000 tread parts alone

I wanna know how much they make the product for and what the profit is from 1 set alone

Like other have been saying this model looks like a WIP, but it is an official set. I personally think the B model looks better. Although, I think it is dumb that the B model doesnt use the buckets as a bucket... just like 42043 b model...

Sorry I don't do pneumatics, what is the problem?

It almost looks like a wing nut style end to an axle. is instead of using a small bevel gear, you spin that to do the function

I know someone that helped me out with this a while ago. The concept works great, but you have more than one battery box to supply more voltage.
