Patent number: 9862374Abstract: A series hybrid transmission includes a first motor device for driving a first shaft, a second motor device for driving a second shaft. Drive gears on the first and second shafts can be simultaneously engaged in the same or different gears and torque from the two motor devices can he multiplied. When shifting up or down, the drive gear on one of the shafts can be disengaged while the drive gear on the other one of the shafts remains engaged to avoid interruption in application of torque.Type: GrantFiled: November 29, 2012Date of Patent: January 9, 2018Assignee: Mack Trucks, Inc.Inventor: John Jerwick

Patent number: 9188176Abstract: A transmission with a countershaft brake includes a countershaft, a positive displacement pump including a pump housing having a chamber with an inlet and an outlet, the pump being driven by the countershaft, and a flow restrictor disposed at or downstream of the chamber outlet, the flow restrictor being adjustable to increase and decrease an amount of flow restriction from, the outlet of the chamber. Torque needed to drive the pump increases with an increasing flow restriction by the flow restrictor. A method for braking a countershaft in a transmission is also provided.Type: GrantFiled: August 19, 2011Date of Patent: November 17, 2015Assignee: Mack Trucks, Inc.Inventors: John Jerwick, Michael E. Kahl

Patent number: 9157347Abstract: A method of operating an engine includes starting and stopping operation of an internal combustion engine that includes a crankshaft having a bearing journal and a bearing in which the bearing journal is rotatable. The crankshaft is constantly turned when the internal combustion engine is in the non-fueled mode. An oil pump can be driven to lubricate the bearing journal and the bearing while the internal combustion engine is in the non-fueled mode to provide hydrodynamic lubrication. An engine is also disclosed.Type: GrantFiled: October 20, 2010Date of Patent: October 13, 2015Assignee: Mack Trucks, Inc.Inventors: John Jerwick, John Bartel

Patent number: 8789433Abstract: A transmission capable of triple overdrive includes a main box section connected to a first input shaft. The main box section comprises clutch collars which are connected to the main shaft and axially movable by an operator to selectively couple one main shaft gear to a main shaft via a countershaft gear fixed on a countershaft. An auxiliary section is connected to the main box section and contains a splitter section and a range section. An output shaft is connected to the auxiliary section The transmission is selectively configured Io operate in a plurality of gear combinations. At least three of the gear combinations are configured for overdrive. The main box section is connected directly to the splitter section.Type: GrantFiled: October 18, 2010Date of Patent: July 29, 2014Assignee: Mack Trucks, Inc.Inventors: John Jerwick, Michael E. Kahl

Patent number: 8337357Abstract: A parallel hybrid vehicle launches from rest or near rest with its internal combustion engine and with its electric motor/generator in generator mode, accelerates to a maximum speed, and decelerates to rest with its internal combustion engine disengaged and its motor/generator in generator mode. Electrical energy generated is stored in an energy storage device and is only as much energy as needed for operation of the vehicle's electrically powered auxiliary equipment while the vehicle is at rest.Type: GrantFiled: February 22, 2007Date of Patent: December 25, 2012Assignee: Mack Trucks, Inc.Inventor: John Jerwick

Patent number: 8292780Abstract: A powertrain includes a prime mover, a transmission, an input shaft adapted to transmit torque between the prime mover and the transmission, an output shaft adapted to transmit torque between the transmission and a driveline, and a master clutch between the prime mover and the input shaft, the clutch being movable between a disengaged position and an engaged position in which the clutch is not and is adapted to transmit torque between the prime mover and the input shaft, respectively. An electric motor is arranged for torque transmission with at least one of the input shaft and the output shaft, and a controller is provided for controlling the electric motor to rotate the input shaft at a rotational speed within an operating range of the prime mover when the clutch is moved from the disengaged to the engaged position.Type: GrantFiled: April 28, 2008Date of Patent: October 23, 2012Assignee: Mack Trucks, Inc.Inventor: John Jerwick
