DYNAMIC TRACTION CONTROL SYSTEM

摘要

A transfer case (20) for a motor vehicle having an input shaft (56), a fi rst output shaft (40), a second output shaft (30), a clutch (42), a transfer mechanism (88), a sensor portion (500) and a magnetoelastic torque sensor ( 506). The clutch (42) has a clutch pack (152) and a thrust mechanism (170) t hat is configured to exert an engagement force on the clutch pack. The clutc h pack has a first portion (154), which is rotatably driven by either or bot h of the input shaft (56) and the first output shaft (40), and a second port ion (78) that is supported for rotation relative to the first portion (154). The transfer mechanism (88) couples the second portion of the clutch pack t o the second output shaft (30). The sensor portion (500) is coupled to the f irst or second output shaft and is at least partially formed of a magnetoela stic material. The magnetoelastic torque sensor (506) is disposed about and radially in-line with the sensor portion (500).
