hehe nei en kompis oppi høgget her som kjøpte den. Jeg har en original eGT 4x4 på handen som jeg driver og vurderer litt omkring :)

 

Ikke vært å forakta å hatt en 4x4 gti-r primera med forsterket gti-r kasse og diff sperrer...

ATTESA - Advanced Total Traction Engineering System for All-terrain

 

Yep, that’s what ATTESA stands for and that’s what it does, except it is not so advanced. One thing to note about the ATTESA system in the GTi-R is that it is not electronically controlled. The R33 and R34 Nissan Skyline GTR have the electronically controlled version of this but that system has the actual name of ATTESA-ETS. The R32 and ["luxury"] GTi-R Nissans have a mechanical system based on so called clutches

 

GTi-R Rear Diff and front diff: It may not be called an LSD by most people but in fact it's design and function are very similar. The basic function of the limited slip diff is to distribute power to the wheel with the most traction. The GTi-R ATTESA set up is built to do this. The rear and front diffs have clutches in them (well almost), these look like a CDROM disc with the last 1-2cm of the CDROM bent out on an angle. These clutches work in a surprisingly easy way. When the person driving the car puts the foot to the floor so to speak there are a several events that happen.

 

1, The power to drive shaft increases.

2, The spider gears push the side gears away from the diff towards the wheels.

3, This increased load (push) causes the clutches to straighten and lock.

4, The lock increases the power to that wheel. (remember this happens to both sides of the car).

 

What happens when a wheel loses traction, the clutch on that side of the diff will lose its lock and therefore power will be forced onto the other wheel. simple?

 

The centre diff on the GTi-R:

There are 2 type systems used on GTi-Rs, If you own a rally version you should be able to see the centre diff underneath your car. If you own a road version the centre diff is actually incorporated inside the gearbox housing. The reasons for this are obvious as the rally cars may have needed to have the centre diff changed during a rally and the easiest way to do this is to have the centre diff on the outside of the gearbox. These 2 systems function in the exact same way though.

The ATTESA 4WD system is not a true all time 4WD. The rear diff has a viscous coupling permitting both wheels to drive under power, if one looses drive it is then transferred to the opposite wheel locking the rear drive shafts as one, the front is a conventional spider gear diff with no viscous coupling inside thus power is lost when one front wheel loses traction, the front viscous coupling sits between the transfer case and drive shaft to the rear diff, which would allow a certain amount of slip to the rear diff. Drive from the gearbox is always available to the rear wheels through the transfer case. If 4WD was to be maintained all the time ie. 4 wheels truly under power you would not suffer from oversteer as GTiR 's do because the car would be pushed and pulled through a corner not just pushed. If you look at the homologated GTiR its a totally different ball game, as it is a true all time 4WD dependant on what diff and transfer case combination you choose. It had additional electronic torque split and controlled slip diff with an automatic rear torque releasing system. In race or rally cars all time 4WD is feasible as with wheel spin or lifting off one or more wheels during hard cornering you dont suffer from diff bind as you would in a road car. Hope this helps without getting to technical, (all this is out of the w/shop manual & the original FIA GTiR Homologation Grp A Forms)

 

Dette fant Google om Pulsar/Sunny GTI-R's 4WD-system. Så... Har Primeraen GTI-R'ens clutch-LSD-bakdiff?
