PRE-EMPTIVE ELECTROMAGNETIC CLUTCH APPLY SYSTEM

摘要

The present invention uses a solenoid to directly apply a wet clutch system for either a four-wheel drive or all-wheel drive coupling, or on-demand transfer case system. The present invention is a clutch assembly which includes an input member, an output member selectively connected to the input member, a clutch pack, an actuation plate having at least one arm which is disposed along the clutch pack with the arm having an extension for compressing the clutch pack, and a solenoid actuator operably associated with the actuation plate. When the solenoid actuator is activated, the actuation plate will be drawn toward the solenoid actuator, causing the extension of the arm to compress the clutch pack, forcing the input member and the output member to rotate together.
