Patent number: 8556772Abstract: A manual transmission clutch protection apparatus includes a shift gate cylinder acted upon by the operator controlled shift lever having a first shift pattern that represents all possible shift positions and two or more additional but limited shift patterns corresponding to certain gears which limit the gears selectable and enagageable by the vehicle operator. Two or more actuators which may be solenoids or other electric, hydraulic or pneumatic actuators translate blocking pins or plungers into the additional or limited shift patterns to lockout or block motion of the shift lever and shift gate cylinder into certain gears. Engine speed and temperature sensors, a vehicle speed sensor and a current gear sensor provide data which is utilized to compute which gears, under current sensed operating conditions, should be locked out, that is, unavailable for selection by the vehicle operator.Type: GrantFiled: May 27, 2011Date of Patent: October 15, 2013Assignee: GM Global Technology Operations LLCInventor: Jeffrey J. Biallas

Patent number: 7543520Abstract: A transmission includes a transmission case, which defines a generally cylindrical bore that is sufficiently configured to pilot a fastening block member therein. A generally annular groove is defined by the transmission case and is sufficiently dimensioned to receive a snap ring. The snap ring operates to limit the axial movement of the fastening block member with respect to the generally cylindrical bore. An extension housing having a hub portion is also provided. A flange portion extends generally radially outward from the hub portion. The flange portion defines at least one bore that is sufficiently configured to receive a threaded fastener. Similarly, the fastening block defines at least one threaded bore sufficiently axially aligned and configured such that the fastener can threadingly engage the fastening block to secure the extension housing with respect to the case.Type: GrantFiled: January 27, 2006Date of Patent: June 9, 2009Assignee: GM Global Technology Operations, Inc.Inventors: Paul D. Stevenson, Edwin T. Grochowski, Jeffrey J. Biallas

Patent number: 7445079Abstract: A method for automatically calibrating a transmission of a vehicle using load sensing includes sensing a change in ride height of the vehicle and measuring a magnitude of the change in ride height of the vehicle. The method includes selecting a predefined set of parameters to calibrate the transmission depending on the magnitude of the change in ride height and calibrating the transmission using the selected predefined set of parameters.Type: GrantFiled: November 21, 2005Date of Patent: November 4, 2008Assignee: GM Global Technology Operations, Inc.Inventor: Jeffrey J.

Patent number: 7052430Abstract: A powertrain includes a power transmission having an input shaft continuously connected directly between an engine and a planetary gear member of a first planetary gearset. Another member of the planetary gearset is selectively grounded by a torque transmitting mechanism to establish a reaction member during the launch of a vehicle incorporating the powertrain. The reaction member is established during both the lowest forward drive ratio and the reverse drive ratio. A third member of the planetary gearset transmits the torque from the input shaft, as modified by the planetary gearset, to other planetary gearsets in down stream power flow arrangement with the first planetary gearset.Type: GrantFiled: June 7, 2004Date of Patent: May 30, 2006Assignee: General Motors CorporationInventors: Paul D Stevenson, Scott H Wittkopp, Richard A Winship, James B. Borgerson, Joel M. Maguire, Kent H. Kienzle, Donald L. Dusenberry, Jeffrey J. Biallas, Clinton E. Carey

Patent number: 7036644Abstract: A torque-transmitting mechanism having a latching apparatus includes a frictional drive connection between two components of a transmission mechanism. The torque-transmitting mechanism is controlled in engagement and disengagement through an apply piston to which an apply component is presented. The latching mechanism will prevent disengagement of the torque-transmitting mechanism even when the apply force is disestablished. The latching mechanism is provided with a controlled release to permit the apply force to be reestablished and thereafter control disengagement of the torque-transmitting mechanism.Type: GrantFiled: May 21, 2004Date of Patent: May 2, 2006Assignee: General Motors CorporationInventors: Paul D. Stevenson, Jeffrey J. Biallas, Clinton E. Carey

Publication number: 20040099491Abstract: A brake band and apply mechanism includes a brake drum and a brake band surrounding the drum. The brake band is enforced into engagement and disengagement with the drum through an apply mechanism which includes a rotary electric motor and a linear output member. The linear output member is operatively connected with the brake band. A rotary-to-linear transfer or torque to thrust mechanism is disposed between the motor rotary output and the brake band linear input to enforce engagement and disengagement of the brake band. The motor power is only required during apply and release of the band.Type: ApplicationFiled: November 25, 2002Publication date: May 27, 2004Inventors: Paul D. Stevenson, Jeffrey J. Biallas

Patent number: 6699153Abstract: A braking clutch is provided for a transmission which includes a transmission housing and a plurality of planetary gear members. The braking clutch includes a floating caliper movably supported on the transmission housing. An apply hub is actuated by an electric motor. A rotor is operatively connected to one of the planetary gear members and has a portion extending between the floating caliper and the apply hub to enable selective braking of rotation of the rotor by frictionally engaging the portion of the rotor between the floating caliper and apply hub, thereby braking rotation of the planetary gear member.Type: GrantFiled: April 19, 2002Date of Patent: March 2, 2004Assignee: General Motors CorporationInventor: Jeffrey J. Biallas
