Patent number: 10608497Abstract: An electric power system includes an engine, a generator, a drivetrain including a driveshaft, and an energy storage system having a flywheel. In an implementation, a parallel-path continuously variable transmission is structured to transfer energy between the flywheel and the driveshaft, and in another implementation a parallel-path continuously variable transmission transfers energy between the engine and the generator. The transmission includes a variator and a differential geartrain. An electric motor is coupled to the flywheel and charges the flywheel such that stored flywheel energy is available for bringing up engine speed from a standby state and/or to accommodate generator load changes with limited generator speed changes.Type: GrantFiled: December 18, 2017Date of Patent: March 31, 2020Assignee: Caterpillar Inc.Inventors: Evan Jacobson, John Seipold

Publication number: 20060021455Abstract: A power takeoff assembly having a brake assembly operable to prevent undesirable rotation of a power takeoff shaft when the power takeoff shaft is in a disengaged state. A clutch assembly is placed in an engaged state when pressurized fluid from a pressure source causes a first clutch element to engage a second clutch element such that the input shaft drives the power takeoff shaft. The clutch assembly is placed in a disengaged state when pressurized fluid from the pressure source is removed from the clutch assembly. The brake engages an output of the input shaft when the clutch assembly is in the disengaged state to prevent fluid forces within the clutch assembly from driving the power takeoff shaft.Type: ApplicationFiled: September 27, 2005Publication date: February 2, 2006Inventor: John Seipold
