Traction force open/closed loop control system for four-wheel drive (FWD) vehicle

A traction force open/closed loop control system in a FWD vehicle has a differential for the front and rear wheels driven by the engine. The differential has a drive bevel gear (26) and a follower bevel gear (25) which transmit the driving force from the input shaft (18) to a clutch drive shaft (23)...

Beschreibung
Zusammenfassung:	A traction force open/closed loop control system in a FWD vehicle has a differential for the front and rear wheels driven by the engine. The differential has a drive bevel gear (26) and a follower bevel gear (25) which transmit the driving force from the input shaft (18) to a clutch drive shaft (23) transverse to the vehicle body. There are clutches located between opposite ends of this shaft. There is something to determine the vehicle speed and something to control in open or closed loop fashion the lowering of the maximum torque transmitted through the clutches in proportion to the increasing vehicle speed.
