Костя, а правда что

Правда что после набора определенной скорости муфта "жестко" блокируется с определенным соотношением момента?

То RopRun: Уточника про какой МК ты говоришь. На мк2 ставили муфту халдекс второго поколения.

2 вопроса

1. НА какой именно скорости блокируется ?
2. В чем различие между первым и вторым поколением Халдекса на ТТах ?

Спасибо.

МК2. Очень бы интересно этот вопрос узнать.
Я точно знаю, что на МК2 15% момента всегда сзади и то я не уверен, что такого же не было на МК1

Вот что пишут в Википедии:
Вообщем я запутался как на самом деле момент гуляет перед-зад.

Starting from 1998, the Swedish Haldex unit replaced the viscous coupling. Haldex is used on the Audi A3/S3, Audi TT, Mk4 and Mk5 generations of Golf, Jetta and R32, VW Sharan, 6th generation Passat (also based on the A-platform) and 5th generation Transporter (van). On the Audi's, the trademark holds true and is referred to as quattro, where the Volkswagens receive the 4motion name. The Škoda Octavia 4x4 and SEAT Léon 4 and Alhambra 4 also used Haldex, being based off of Volkswagen models. Curiously, the Bugatti Veyron also utilizes Haldex, though with separate transmission, PTU and front and rear axles.

What: Automatic all wheel drive (on demand).

Haldex multiplate clutch with electronic control acting as a center differential.

Open rear differential, EDL on some models (not proved).

Open front differential, EDL.

How: Normally front wheel drive vehicle. In normal driving conditions near 100% of torque transferred to front axle. When slipping occurs, Haldex multiplate clutch locks and up to near 100% of torque is automatically transferred to rear axle. Haldex clutch offers instant activation – it locks as soon as one driveshaft travels just 1/8 of a turn further than the other. Front wheels do just 1/4 of a turn before AWD is activated. Accompanied by EDL on front wheels, in on-road conditions the car will not move if both front and one rear wheels lose traction.

Again, due to limitations of Electronic Differential Lock (see quattro IV description above), in off-road conditions it is enough for one front and one rear wheel to lose traction and the car will not move.

The Haldex system is more reactive than preventative; the Torsen's even power split under non-slipping conditions makes slipping less likely to start, while the Haldex's greater torque split under slipping conditions is helpful for recovery.

Haldex Electronic Control Unit disengages the clutch as soon as brakes are applied to allow ABS work properly; it also disengages the clutch when handbrake is pulled to allow “handbrake turns”. When performing tight low-speed turns (e.g. parking) the clutch is disengaged by Electronic Control Unit to avoid wind-up in transmission.

Вообщем нужно что бы Костя все расставил по своим местам.
