Detroit truetrac uses helical cut gears instead of clutches. It works really well, even off road it works almost like a locker unless you pull a tire. Only problem we had with one was the ring gear bolts backed out even after being torqued with red loc tite. I'm sure that wasn't caused by the diff.
When you come out and say to someone who has years of experience " I have more experience then you " you better be able to back it up. By the way did you read what "EATON" wrote about the "Detroit Locker" that they manufacture ? If you did, you would have read that they only recommend using it on vehicles that spend less then 25% on pavement. They go on to say about the extra load on driveline parts. As far as all the other manufacturers using "Lockers" they don't. They use "limited slip" differentials. A big difference ! I still see that you never supported your claim with any evidence, at least I presented the actual paper from the manufacturer. To Merunimog404, the Germans are not the "end all be all". After all we won the war !!! And if you would care to research, the Unimog is an "offroad" vehicle made for the German military . If you try and come back with "they drive them on pavement" I'll say " that's why they jack them up so high to be able to drive over VW's " Also I'm sure it is hard to drive in all that frozen slush you get in Reno !
The component your talking about is the "compensator" and yes it is a differential that splits the power between the front and rear differentials. The most famous that I know of is the Rockwell SQHD for 18 wheelers. At one shop I worked at, I was required to build up 4 (minimum) of them a day. Or 3 medium transmissions or 2 large transmissions or 2 large differentials or etc.
Well winning the war is not proof that we make better equipment
. I have a Unimog and I drive it on the road.
I decided to post again as I didn't know much about the "unimog". So after reading up on it I found out that they use a locking axle system that literally locks the axles to each other. I have worked on other systems like this and I assure you it is NOT a "Locker" style differential. And M-1028, no vehicle uses "Detroit Lockers" in there vehicles from the manufacturer ( if I'm wrong, someone show me who does use them and I will retract my statement) There is no such thing as an "electric locker". Lockers are mechanical .Well winning the war is not proof that we make better equipment
#1 it has selectable lockers.
#2 I have owned a truck that had lockers front and rear. It's still on the road 12 years later.
#3 what in the world are you talking about with jacking the Unimog up? It's that high from the factory and it has nothing to do with driving over a vw.
#4. What is it with your obsession with slush. Slush isn't hard to drive in. Ice is a lot more slippery than slush.
We get, with the exception of this winter lots of snow and ice here in northern Nevada.
Wait. So the axle shafts are locked together, but it's not a locker. Hhhmmmm. That's different. What they do is turn it into a spool. But it's non the less locked. I'm not even sure where limited slips even came from in the conversation. A limited slip is a differential as is a Detroit locker. They allow differential action in a turn. But that's where the similarities end. I'm very familiar with lockers. As I've said I had a ramcharger that had lockers front and rear. I couldn't turn them off and on. They were locked just like the Detroit in the 1008. My Unimog as lockers. Even in the site you posted sad they come with locking differentials.
OK one more time. In the "unimog" there is a sliding gear on the axle itself, that when engaged is locked into the carrier housing becoming at that point a "spool" differential. A true "locker" which by the way is a trade name like "Band-Aid" or "posi" (GM) locks and unlocks as the difference of the left and right wheel come and go out of synch, as in a turn. The GM built 1008 does not have a "Detroit Locker" it has a "limited slip" differential . I truly believe now that you guys who are arguing with me do not understand all the different types of differentials out there and are assuming that locker describes all types of torque equalizing differentials. I am not being sarcastic when I say do some reading on the many types of differentials that are made. Then you will understand what I have been trying to say to you all along.
Screen shot off of my phone of the 34TM. Sure looks like a "no-spin". The description of all the CUCV's except the 1009 list a no-spin. We all know who built them. Eaton. A locker by any other name is still a locker.
This is simply not true. So you're saying the ARB air locker, mechanically shifted lockers like the Ox-Locker, numerous electronically actuated eLockers, and all the new electronically actuated lockers from the light truck and Jeep OEMs are not actually lockers because they don't lock and unlock throughout a turn??????
Really? What trade name coined this phrase? I agree that 'posi' is a GM thing that gets infamously mis-applied, but what product was coined 'locker'?
Honestly, if the basis for any 'discussion' is to equate the decision of a defense contractor and the person in charge of signing the contract that day to that of a decision based on logical reason, good engineering practices, or purpose via experience is purely arbitrary.
The 1008 has a Detroit locker. It does not have a limited slip. I know what my Unimog has.
Phil2968 I was wrong, the 1008 I owned had a 14 bolt with a limited slip differential, So I assumed all the rest did too. Mia Culpa .
I found out the 1008 does come with a "Detroit Locker" but the "unimog does not and here is a picture from there site.
It's a **** locker man. There is zero difference in wheel speed between either wheel when it's locked. No drop it please.
You hit the nail on the head. I'm guessing the only differential that can be called a locker is a Detroit? I never said any vehicles came with DETROIT LOCKERS, I said LOCKERS, as in a LOCKING differential.
Mudguppy, what does differential mean ? It means to differentiate , that means it is responding to two or more things, understand ? A "Spool" does NOT differentiate since it cannot turn, it is mechanically fixed, it is unable to turn.
