Title:
ELECTRICALLY ACTIVATED MULTIPLE DISC CLUTCH FOR A TORQUE TRANSFER MODULE USED IN ALL-WHEEL DRIVE
Document Type and Number:
WIPO Patent Application WO2002068838
Kind Code:
A3
Abstract:
A front or rear torque transfer module system (A) for an all-wheel drive vehicle (V) includes a housing (5) containing two rotating shaft members (10 & 15) connected by a clutch (113). The clutch (113) is activated when a braking mechanism such as an electromagnetic, hysteresis or eddy current brake (260) modulates the relative rotation between a clutch pressure plate (175) and the second rotating shaft member (15). The difference in relative rotation forces two opposing ramped surfaces (65) into opposition to induce the clutch pressure plate (175) to compress a set of interleaved clutch discs (160 & 165) thereby transferring rotational motion between the first rotating shaft member (10) and the second rotating shaft member (15).
