Patent number: 8874337Abstract: A system according to the principles of the present disclosure includes a selected gear module and a shift indicator module. The selected gear module determines a selected gear of a manual transmission. The shift indicator module monitors vehicle speed and the selected gear and generates a shift indicator signal based on the vehicle speed and the selected gear, the shift indicator signal indicating when to shift to one of first gear and reverse gear.Type: GrantFiled: September 6, 2011Date of Patent: October 28, 2014Inventors: William L. Cousins, James M. Partyka

Patent number: 8798880Abstract: A system according to the principles of the present disclosure includes an engine speed module and a downshift indicator module. The engine speed module determines an engine speed when a clutch is engaged with a dual mass flywheel. The downshift indicator module generates a downshift indicator signal when the engine speed is less than a first speed, the downshift indicator signal indicating when to downshift a manual transmission.Type: GrantFiled: September 23, 2011Date of Patent: August 5, 2014Inventors: William L. Cousins, James M. Partyka

Patent number: 8636125Abstract: A dual clutch actuation device generates the axial compression force required to compress a first and second set of frictional elements of a dual clutch module. Dual clutch actuation device includes a first and second annular piston. The annular pistons are arranged in concentric annular piston slots. Together the piston and annular slots form annular piston chambers. The actuation device further includes a first set of wiper seals and a second set of wiper seals disposed in a first and a second annular channel in each of the annular pistons. Advantageously, contamination of the piston chambers is reduced or eliminated through the wiping or cleansing action of the first and second set of wiper seals against walls of the annular slots formed in the housing of the actuation device.Type: GrantFiled: August 13, 2010Date of Patent: January 28, 2014Assignee: GM Global Technology Operations LLCInventors: John A. Diemer, Edward J. Billings, Joakim Hogberg, James M. Partyka, Robert Neil Paciotti

Patent number: 8634996Abstract: A method of cooling a dual clutch transmission is provided. The transmission has first and second input clutches alternately engagable to transfer torque to an output member along first and second input shafts, respectively, at various speed ratios dependent upon engagement of synchronizers. The method includes determining a currently established speed ratio by determining which of the input clutches and synchronizers are currently engaged and which of the input clutches and synchronizers are currently open. One of the open synchronizers is then engaged during the currently established speed ratio to cause the open input clutch to rotate at a speed greater than the speed of rotation of the engaged input clutch, thereby creating a fan cooling effect.Type: GrantFiled: September 28, 2010Date of Patent: January 21, 2014Assignee: GM Global Technology Operations LLCInventors: Larry D. Diemer, Scott William Heitzenrater, James M. Partyka, Victor M. Roses

Patent number: 8485333Abstract: A dual clutch actuation device generates the axial compression force required to compress a first and second set of frictional elements of a dual clutch module. Dual clutch actuation device includes a first and second annular piston. The annular pistons include a first end that is in contact with annular bearing assemblies. The annular bearing assemblies are in contact with actuation levers that are in contact with the first set of frictional elements. The annular pistons are arranged in concentric annular piston slots. Together the piston and annular slots form annular piston chambers. The piston chambers are filled with hydraulic fluid. When the hydraulic fluid is pressurized the pistons slide out of the annular slots and apply a force on the actuation levers which in turn apply an axial compression force on the frictional elements.Type: GrantFiled: August 13, 2010Date of Patent: July 16, 2013Assignee: GM Global Technology Operations LLCInventors: Joakim Hogberg, Uwe Krist, James M. Partyka, Robert Neil Paciotti, Stefan Gebert, Jurgen Ryba

Patent number: 8413780Abstract: A device for transmitting torque between a flywheel rotatably connected to an engine and a dual clutch transmission. The device includes a first substantially u-shaped member fixed to a perimeter of a dual clutch of the dual clutch transmission. The first substantially u-shaped member defines a slot having an open end. The second substantially u-shaped member is attached to a perimeter of the flywheel. The second substantially u-shaped member includes a support member for supporting an engagement member. The first substantially u-shaped member fits at least partially within the second substantially u-shaped member. The pair of bushings disposed proximate the engagement member between the first and second coupling members.Type: GrantFiled: August 13, 2010Date of Patent: April 9, 2013Assignee: GM Global Technology Operations LLCInventors: Servet Yildiz, Markus Haehle, James M. Partyka, Robert Neil Paciotti
