Patent number: 9702416Abstract: The present invention uses a sensor to determine when a pressure plate and a clutch plate of a dual clutch transmission system are in contact with one another. The assembly includes a housing having a plurality of pistons connected to both the clutch plate and pressure plate. The pistons contain either magnets or couplers and are positioned adjacent one another separated by either a Hall effect sensor or an inductive sensor. As the pressure plates and clutch plates come into contact with one another the pistons move within the housing and said movement is detected by the sensor. The sensor determines if the pressure plate is in contact with the clutch plate and if the clutch plate or the pressure plate has traveled any linear distance.Type: GrantFiled: November 10, 2014Date of Patent: July 11, 2017Assignee: KSR IP Holdings, LLCInventors: Lingmin Shao, Jim Hartford

Patent number: 9657783Abstract: A clutch module for a dual clutch transmission (DCT) is designed to improve circumferential fluid distribution to reduce or eliminate an unpleasant noise during engagement. In some embodiments, the reaction plate is restrained in a position offset 1-3 degrees from perpendicular to the housing axis. Consequently, 0.2-0.7 mm of clearance remains on one radial side of the clutch when all clearance has been removed on the other radial side of the clutch. Relative rotation between the hub and the housing pushes fluid from the tight side toward the loose side. In an alternative embodiment, the piston is designed to orient the pressure plate non-perpendicular to the housing axis.Type: GrantFiled: January 20, 2015Date of Patent: May 23, 2017Assignee: Ford Global Technologies, LLCInventors: Matthew Thomas Trent, George Frederick MacDonald, Bryant David Grytzelius
