Welded dif ?

[cloughy]

Nah I read it perfectly clear thanks, I'm saying there is a massive difference between a direct driven 1 wheel only compared to a standard open differential Maybe you should re-read my post






Although it may not make sense

But if its welded, and have only one hub locked in, at the first sign of any rolling resistance wont all the drive go to the easier side?? In which case, it would get sent to the unlocked side So if its welded front with one hub unlocked = same as open front... untill you lock the hub in

[bucketofbolts]

na, coz it will send the power to the locked axle,

Your mechanically inebt, aren't you

Maybe, but at least i can spell INEPT

No, it will send half the drive to each shaft.. although one shaft is not locked in at the hub end. Hence one wheel will drive, yet it will recieve half the power coming to the front diff.

The diff centre will be fully locked when welded, and the hub being locked in makes no difference to how the shafts will turn. The shafts rotate at a 1:1 ratio at all times.
Its just that unlocking one hub allows you to turn.

No, it will be 100% positive to that wheel

Ok, I have a beer now, and thought about it summore

You will get equal drive to both SHAFTS. So a 50/50 split of the engines power down each axle shaft, but if one hubs unlocked, then only one wheel (the one that is locked in) will get drive to it, hence it only gets 50% of the engines power. But since there's no resistance on the other side since its not locked in, the 'power' sorta goes to the wheel thats locked in anyway. So its 50% but its 100% aswell

Nah its just 100%, theres no differential action to split it

[RockyF75]

But how can you have 100% to each axle (becomes 200% in total )? Cause the unlocked axle would still be spinning, just not have much load on it, so it would be a 99-1 split

I give up

[azzad]

Does it really matter what percentage of power?

Welded diff with one hub locked will only drive the wheel with the locked hub. The axles will still be turning at the same speed but the freewheeling hub will have no drive to the wheel.

Ok, i sorta get it now... I did some reading

I automatically thought as there is no differential action ocurring, the torque coming in could not be split up.. hence they get equal amounts.
Now i can see that the wheel on the ground will get all the drive... I think

Found this which sums it up...

This is great when you have no traction on one side, because no matter what, both sides turn at the same speed, and if one side offers lots of resistance, and the other none, then effectively all the "usable" or "useful" torque goes to the side where there is resistance. It's getting 100% of the available torque. The side with no traction doesn't need torque to spin helplessly, so it's not really getting 50% of the torque as you might think.

[HotFourOk]

This throws a spanner in the works for my thinking also...

A rule first: The unlocked differential always distributes torque equally left and right. It allows for unequal velocity - but torque distribution is always equal.
