hej

ciekaw jestem czy ktos przerabiał temat szpery do tylnego dyfra w audi 80 /S2 ?

ja znalazłem Wavetrac

http://www.wavetrac.net/application.htm

niby life time warranty, zdaje sie 600NM

ktoś kojarzy cos lepszego ?

niestety torsen do jazdy torowej nie bardzo...

peloquin, Quaife, OBX zdaje sie mają tylko na przód... ?

wavetrac to trochę więcej niż torsen - poczytaj dokładnie.
trochę ich się sprzedaje i wg. mnie jest to chyba najlepsza szpera "zębata"

pewnie dlatego że jak jedno koło oderwie się od asfaltu to torsen nie działa.

jakie to ma spięcie wstepne, mozna to regulować ?
gdziec wyczytałem ze 600NM jest gwarantowane , no i jak z tą dozywotnią gwarancją wyglada w praktyce ?

udało sie komus tego wavetraca rozwalic ?

no i wytrzymałość i jakośc Gripper vs Wavetrac ?

o torsenie pisałem w kontekscie mechanizmu z tylnego dyfra audi V8, ze nie bardzo na track daye i slicki bo po pierwsze szybko klęka a po drugie jak sie koło wewnetrzne w zakrecie uniesie to nie ma dystrybucji momentu na drugie koło

jakby było jeszcze ze 2 chetnych to pewnie mozna byłoby zejsc do 1200 USD za sztuke






Wavetrac Differential Audi A4 Quattro REAR LSD
Application:Audi A4 Quattro

PART #: 40.309.170WK

Innovative:
Patent pending Wavetrac® design automatically improves grip in low traction conditions. This feature is truly innovative and unlike any other torque biasing diff design.

Superior Materials:
9310 steel gears run in case-hardened billet steel bodies. ARP® fasteners used throughout.

Maintenance Free:
As supplied new, the Wavetrac® differential will perform a lifetime of service without maintenance or rebuilds.

Customizable:
If desired, you can alter the diff’s behavior to suit your needs using optional components.

Limited LIFETIME Warranty:
All Wavetrac® differentials include a transferable, Limited Lifetime Warranty.

To best understand how the Wavetrac® is truly different from the other gear differentials on the market, you first have to understand the primary problem that the Wavetrac® solves.

The problem: Loss of drive during zero or near-zero axle-load conditions.

Zero axle-load is a condition that occurs during normal driving, but creates the most noticeable problems when driving in extreme conditions. Zero or near-zero axle-load is the condition that exists when there is ‘no-load’ applied through the drivetrain, when one drive wheel is nearly or completely lifted (often in aggressive cornering). It also occurs during the transition from engine driving a vehicle to engine braking and back, even with both drive wheels firmly on the ground.

Here’s how that loss of drive hurts you:
1) If you lift a wheel, all gear diffs except Wavetrac®, will NOT power the other wheel.
2) During the transition from accel to decel, all gear diffs except Wavetrac®, do nothing.

Why does this happen?

All gear LSDs (including Torsen®, Truetrac®, Quaife®, Peloquin, OBX, etc.) work in basically the same manner: they divide the drive torque between the two axles, applying drive to each side, up to the available grip of each tire. The amount of drive torque one wheel can get over the other is described as the bias ratio, a measure of the torque split across the axle.

Standard, open differentials have a bias ratio of 1:1. They can only apply as much drive torque as there is available traction at one wheel. When one wheel loses grip, the total available drive is lost as well (at a 1:1 ratio). All your power goes out the slipping wheel - along the path of least resistance.

Torque biasing differentials offer increased bias ratios over open differentials. For example, if a diff has a bias ratio of 2.5:1, then it can apply drive torque to the wheel with the most traction (gripping wheel) at 2.5 times the traction limit of the wheel with the least traction (slipping wheel). This is a significant improvement over an open diff… most of the time.

The problem is that when one tire has LITTLE or NO grip (zero axle-load), the other wheel gets ZERO DRIVE, because (basic math here): 2.5 x 0 = 0.

Lift a wheel (or substantially unload a wheel) and you get zero axle-load on that side - that means that during the time the wheel is unloaded, the typical diff will NOT power the wheel that’s still on the ground. No matter how high the bias ratio, you get no power to the ground.

During the transition from accel to decel, where you have near zero torque on the axle, even if the wheels are on the ground, the typical diff is unable to begin applying drive torque until AFTER the zero torque condition is over. While this condition is generally short-lived, the fact that most diffs can do nothing during that time means that there will be a delay once the zero torque condition stops - creating a reaction time in the driveline.

The Wavetrac®, however, is different:



The innovative, patent-pending, Wavetrac® device in the center of the diff responds during these exact conditions when zero or near-zero axle-load occurs. At or near zero axle-load, the axles (and therefore each side gear in the diff) start to turn at different speeds.

This speed differential causes the Wavetrac® device to step into action:



Precisely engineered wave profiles are placed on one side gear and its mating preload hub. As the two side gears rotate relative to each other, each wave surface climbs the other, causing them to move apart.

Very quickly, this creates enough internal load within the Wavetrac® to STOP the zero axle-load condition.

The zero axle-load condition is halted, and the drive torque is applied to the wheel on the ground (the gripping wheel)… keeping the power down.

Some gear differentials rely solely on preload springs to combat loss of drive. The drawback is that you can’t add enough preload to prevent loss of drive without creating tremendous handling and wear problems at the same time. So, to avoid these problems, the preload from ordinary spring packs must be reduced to a level that renders them ineffective at preventing loss of drive. The Wavetrac® is the only differential that can automatically add more load internally when it’s required.

In the case where both wheels are on the ground during zero axle load, such as during a transition to deceleration, the Wavetrac® device is able to prepare the drivetrain for when the zero torque condition stops, eliminating the delay seen with ordinary gear diffs.

What this means for you as a driver is that power is delivered to the gripping wheels for more time and in a more constant manner – making you faster and improving stability.

The Wavetrac® truly is different - and its innovative features can make a real difference in your car’s performance.

Here’s something else you won’t find in any other design:



The Wavetrac® diff’s behavior can be altered in the field to suit your needs. It comes standard with carbon-fiber bias plates for the best all around performance and lifetime durability. Changeable plates using materials with different friction coefficients to fine-tune the bias ratio are sold separately.

These bias plates provide a mechanism to tune the response of the differential as a function of applied torque load. The applied torque load manifests itself as an axial load from the differential pinions into the housing. This axial force is then considered a normal force into the bias plate, and as a function of the effective coefficient of friction, provide a resistive torque to the rotational motion of the differential pinions. The resistive torque will add to the resistance of relative rotation of all components within the differential. The resistive force, however, is non-uniform since it is a function of the axial load from the differential pinions. The unbalance of the resistive torque will manifest as non-uniform energy absorption within the differential causing a bias ratio.

Here are more features that make Wavetrac® even better:

The new Wavetrac® Differential brings current gear technology to the market.
Internally, its gear tooth forms are optimized for strength and improved oil film retention over competitive designs.
Our gear package is smaller, reducing overall mass, yet is more durable since particular attention was paid to the tooth strength - optimized for high torque conditions.
Attention was also paid to the side gear/axle interface, putting as much material thickness as possible in this critical area - most important when power levels get high.

Each Wavetrac® Differential is crafted from the highest quality materials available.
The internal gears are made from high strength 9310 alloy steel.
The diff bodies are machined from case-hardened steel billet.
To complete the package, every Wavetrac® differential is built exclusively using high quality, high strength fasteners from ARP®, the world leader in fastener technology.

no a Wavetrac działa.
wykonanie Wavetrac'a jest też na prawdę dobre - wszystko skręcone na ARP, zęby z dobrej stali- aż przyjemnie pooglądać.

można trochę "spięcie" regulować jakimiś opcjonalnymi podkładkami, ale nigdytgo nie robiłem bo nie było potrzeby.
co do gwarancji nie nie ma z nią problemu tylko dochodzą koszty przesyłki do USA - może będzie można serwisować w EU ale jeszcze nie ma potwierdzonej informacji.

co do trwałości grippera to koła są w miarę wytrzymałe, tylko w mocnych autach płytki się szybko kończą.

nie zamówiłem bo teraz po pierwsze nie jest mi to potrzebne jeszcze, a kasa idzie na biezace rzeczy

mam nadzieje ze bede w wakacje testował to porównam torsena do zaspawanego dyfra

Ja zamontował bym na początku szperę z przodu i wywalił torsena ze srodka, tyl otwarty. Jeżeli auto ma być na tor i ma mieć dużo mocy.

Wavetrac jak weźmiesz w rękę to czuć co to mechanizm różnicowy a nie inne popierdółki - co do wykonania zero uwag jednak jeżeli nie ma szpery ktoś na magazynie to czas oczekiwania na fabrykę 4 m-c...
Jak kidzio napisał - wszystko skręcone na ARP ale bez żadnej regulacji - zakładasz i masz jeździć.
