FAQ

Question: How much power goes to each wheel if I am drivingstraight forward with a constant speed of 100km/h?

Answer: The Haldex coupling will constantly transfer some ofthe engine torque to the rear wheels. However, driving straight atabout 100km/h with no major wheel slip does not require much torquetransfer from a performance point of view. Instead the torquetransfer can be optimized for low fuel consumption. In such asituation, about 10-15% of the total propulsion torque istransferred to the rear axle. However this is very dependent on thecalibration of the particular vehicle model, which is customizedfor every customer.

То есть, при обычной езде это около 10-15% в зависимости отконфигурации. Хотя мне где-то попадалось что конкретно на Йетиоколо 4%.

Haldex gen5 Info

When starting the vehicle, the electrical pump in the Haldex Gen Vis started, swiftly providing the system with pressurized oil andthereby making the system ready for operation. The pump sets thepressure to the piston which in turn compresses the disc package.The level of pressure set depends on the torque level needed and onthe driving situation. In traction/high slip conditions, a highpressure is delivered. In tight curves (i.e. parking) or at highspeeds, a much lower pressure is provided.

Ключевой момент — давление есть всегда когда запущен двигатель. Тоесть задняя ось не может остаться "без присмотра" в принципе.
