Abstract
A hybrid vehicle has a power system with a torsional coupling. The power system includes a battery system for receiving, storing and providing electrical power, an internal combustion engine configured to provide rotational power through a flywheel, a first motor-generator, a second motor-generator, a control system, and a torsional coupling. The torsional coupling may absorb rotational shock caused by angular or rotational speed differences between the engine and the first motor-generator. The torsional coupling includes a driven plate assembly, a cover assembly and an interconnecting plate assembly. The interconnecting plate assembly may include a plurality of shock absorbing elements that absorb shock and vibration between the engine and the motor-generator.
