Maverick II nelivedu
Postitatud: L Mär 10, 2018 11:18 pm
Potentsiaalselt väga loll küsimus aga...
Auto on Ford Maverick II 91kw. Paras linnamaastur, aeglustit ega midagi pole. Praegu lülitab esiveo ja neliveo vahel ise, siis kui tunneb, et vaja on. Võimalik ka pidevaks neliveoks lihtsalt lülitada.
Kas sellisel oleks võimalik mööda minna sellest isetegevusest ja teha see manuaalselt lülitatavaks olukorras kus juht tunneb, et nelivedu vaja - nagu Fronteral nt?

Ameeriaks on seemasin tuntud nimega Ford Escape.
Kuini 2005 olis seel üks süsteem ja sealt edasi tuli juba uus AWD lahendus.
Ford Escape kohta kirjutatakse
Although not meant for serious off-roading, a full-time all-wheel-drive (AWD) system supplied by Dana was optional, which included a locking center differential activated by a switch on the dashboard. The AWD system normally sends most of the power from the engine to the front wheels. If slipping is detected at the front, more power will be sent to the rear wheels in a fraction of a second. The four wheel drive system was a newer version of Ford's "Control Trac" 4x4 system, dubbed the Control Trac II 4WD in the Escape. This system allowed the front wheels to receive 100% of the torque until a slip was detected. Using a Rotary Blade Coupling, the rear wheels could be sent up to 100% of the power in fractions of a second. When switching the system from "Auto" to "On," the front and rear axles are locked at a 50/50 split; the reaction time necessary to engage the rear wheels is reduced via an integrated bypass clutch. The Control Trac II system allows for a four-wheel drive vehicle without the use of a center differential. The entire braking system was built by Continental Teves, including the ABS and various related suspension components
ControlTrac II was a Ford four-wheel drive system based on a viscous coupling unit. The viscous coupling replaced the typical center differential used in four-wheel drive applications. The system worked normally in front wheel drive but in addition to the front wheels being driven, a shaft is powered that runs to the viscous coupling in the rear. If the front wheels slip, the viscous coupling progressively releases torque to the rear wheels. Additionally, the ControlTrac II system provided a mechanical lock of four-wheel drive though there was no low range provided by the system.
ControlTrac II has since been replaced by the automatic Intelligent four-wheel drive system, a similar system with the viscous coupling replaced by a computer controlled clutch. The Intelligent 4WD system functionally acts similar to the ControlTrac II system, with the front wheels being driven predominately with torque being sent to the rear wheels only as conditions dictate. The Intelligent 4WD system also lacks the mechanical lock provided by ControlTrac II.
