Differental Thrust

[tuckertrucker]

Hi guys, I've heard about some trucks with dual live axles, further more having a 60/40 split of torque between the two axles. Meaning one axle gets 60% of the engines torque, while the other axles recieves 40%. How does this work? How is this achieved?
Cheers, Dylan.

Very common these days in virtually any All Wheel Drive.

Vehicle just requires a centre differential which in Off Road application will also have a locker

Torque division from front to rear controlled by onboard 'poota and/or viscous coupling or variable clutching or mechanical torque splitting.
There are almost as many methods as there are manufacturers

Oh wow, I didn't realise its that easy to do.

I wouldn't say easy.. just heaps of options lol..
Imo if your looking at a 6x6 so both rears are driven at all times..
Twin open diffs with lockers fitted..
Be a lot easier.. but still a lot of work..

Slightly off the original topic now, but can torsen diffs be fitted into patrols? Wouldn't they be ideal, as they lock as soon as a wheel breaks loose, and when on paved surfaces they allow differential action. No need for a diff locker or LSD.

Anything can be done.. it's just how deep are your pockets and how nice is your engineer..
