Document Type and Number:
Japanese Patent JP2005511996
Kind Code:
A
Abstract:
A torque coupling connects the secondary driving wheels of an automotive vehicle indirectly to the power unit of the vehicle through a variable torque coupling, while the primary driving wheels on the vehicle are connected directly to the power unit. The coupling compensates for variations in the angular velocity of the primary and secondary wheels while still transferring torque to the secondary wheels. The coupling includes a magnetic particle clutch organized about an axis and a planetary gear set organized about the same axis. The coupling has two paths through which the torque is transferred, one a mechanical path and the other a clutch path. Most of the torque is transferred through the mechanical path, while the clutch path accommodates for slippage and controls the proportion of torque delivered to the secondary wheels, with the control being solely dependent on the magnitude of the current directed through the clutch.
