Men nå er jo Quadradrive (WJ/WG) et helt mekanisk/hydraulisk system uten noe elektrisk/elektronikk.
Som består av 3 "gerotor"-pumper som pumper oljetrykk mot friksjonslameller når det oppstår hastighetsforskjell mellom for og bakaksling (dvs. når bakaksling roterer fortere enn foraksling), samt ved betydelig hastighetsforskjell mellom venstre og høyre hjul.
Så at ABS'en skal ha noen innvirkning der kan jeg ikke helt skjønne ?
I WK (fra 2005-) med Quadratrac I og Quadratrac II har de noe som heter Brake Traction Control System (BTCS) som kanskje er det du tenker på ?
http://www.wkjeeps.com/wk_4x4.htm#QDII"In 2005 Jeep added traction control and replaced the New Venture Gear NV247 transfer case with the NV245 transfer case."
http://en.wikipedia.org/wiki/Jeep_four-wheel-drive_systemsI WK med Quadradrive II derimot har de kjørt inn elektronisk styring på diffene også.
"The ELSD Eaton EGerodisct is a hydraulically-operated electronically controlled limited slip differential that is capable of providing variable torque up to full axle lock."
"The Quadra-Drive II Jeep 4 x 4 system offers owners the ultimate in off-road capability. It combines the NV245 full-time transfer case with Electronic Limited Slip Differentials (ELSD) for best-in-class tractive performance. The system instantly detects tire slip and smoothly distributes engine torque to the tires with traction. In some cases, the vehicle will even anticipate low traction and adjust to proactively limit or eliminate slip.
The heart of the system is the NV245 active transfer case. This transfer case includes a center differential coupled with an electronically controlled clutch pack, varying it from a completely open state to completely locked, and infinite possibilities in between. The 4-Low gear ratio is 2.72:1.
Quadra-Drive II features an electronic shift mechanism with a unique engagement lever. The lever is conveniently located on the shift console. Pulling the lever up engages 4-Low. The lever returns to a resting position after activation. The transfer case also includes a neutral position for trouble-free towing vehicles, such as behind a motor home.
A key component in the Quadra-Drive II system is the ELSD – an industry first application – and the new benchmark for automatic traction differentials. The ELSD use electronically controlled clutch packs to automatically and instantly vary from slip to lock at each axle. This maximizes traction when needed without any of the on-road drawbacks normally associated with such a robust 4 x 4 system.
All components of the system work together, continually monitoring needs, to provide smooth and automatic application of the components for best-in-class tractive performance while improving the day-to-day on-road driving experience. For example, the ELSD releases the clutch packs in the front axle during turns to allow differentiation and prevent crow hop."
