  • Publication number: 20170126159
    Abstract: An electrical power generation system for a vehicle includes a prime mover, an electrical generator to generate electrical power and a gear box operably connected to the prime mover and the electrical generator to transfer rotational energy from the prime mover to the electrical generator. A braking mechanism is located at the gear box to selectably transfer rotational energy from the prime mover to the electrical generator for selective generation of electrical power. A method of electrical power generation for a vehicle includes generating rotational energy at a prime mover, transferring the rotational energy to an electrical power generator, generating electrical power via the rotational energy transfer to the electrical power generator, and periodically stopping and/or starting the transfer of rotational energy from the prime mover to the electrical power generator via a braking mechanism in operable communication with the electrical power generator.

  • Patent number: 9574618
    Abstract: A thermal disconnect assembly for an integrated drive generator includes an input shaft, an output shaft, a eutectic solder, and a disconnect clutch. The input shaft is driven by an external mechanical source. The output shaft is coupled to the input shaft through a disconnect clutch in a coupled state, is driven by the input shaft and rotates with the input shaft in the coupled state. The eutectic solder is configured to hold the output shaft in the coupled state and melt upon reaching a threshold temperature. The disconnect clutch is configured to urge the output shaft toward a decoupled state upon melting of the eutectic solder such that the output shaft does not rotate with the input shaft in the decoupled state.

  • Publication number: 20160348788
    Abstract: An integrated APU-generator constants speed drive system having various features is disclosed. The system may have a gearbox having a differential with a constant speed gearbox output and a hydraulic output controller control shaft. The system may have a hydraulic output speed controller that adjusts the angular velocity of the hydraulic output controller control shaft of the differential. In response, the differential may adjust the angular velocity of the constant speed gearbox output. In this manner, the angular velocity of the constant speed gearbox output may be maintained at a substantially constant angular velocity. A generator may be driven by the constant speed gearbox output. By maintaining the constant speed gearbox output at a substantially constant angular velocity, an alternating current generated by the generator may be maintained at a substantially constant frequency.

  • Patent number: 9470302
    Abstract: Embodiments herein relate to piece-part, sub-assembly, assembly, and component levels of a differential composed of a sun gear configuration and utilized in an integrated drive generator. An integrated drive generator is a hydro-mechanical transmission that drives a synchronous salient pole generator. The integrated drive generator is a constant speed output, variable speed input transmission that includes the differential and a hydraulic unit. In general, the integrated drive generator utilizes the variable speed input from an accessory gear box of an engine to drive or control a hydraulic unit, which in turn drives or controls a churn leg member of the differential. As the differential is driven, speeds of each speed member of the differential are then summed to generate the constant speed output to drive the synchronous salient pole generator.
