Hybrid Vehicle Having Torsional Coupling Between Engine Assembly And Motor-Generator
First Claim
1. A hybrid vehicle having a shock-reducing clutch coupling, comprising:
- a battery system for receiving, storing and providing electrical power;
an internal combustion engine configured to provide rotational power to a flywheel;
a first motor/generator having a hollow rotor shaft rotatably operatively coupled to the flywheel, the first motor/generator configured to;
in a first mode, receive electrical power from the battery system and provide rotational force to the hollow rotor shaft to rotate and start the internal combustion engine;
in a second mode, receive rotational force through the hollow rotor shaft from the internal combustion engine to generate electrical power to charge the battery system;
in a third mode, receive electrical power from the battery system and provide rotational force to the hollow rotor shaft;
a gear transmission having a first port configured to receive or provide rotational power in a first rotational (RPM) range, and a second port configured to provide or receive rotational power in a second RPM range to/from at least one wheel of the vehicle;
a second motor/generator operatively coupled to the first port and configured provide rotational force to the first port when receiving electrical power from the battery system, and configured to generate electrical power to charge the battery system when receiving rotation force from the first port when the at least one wheel provides rotational force to the second port;
a control system configured to control the electrical power provided to and from the battery system; and
a torsional coupling configured to operatively couple the flywheel to the first motor-generator, and reduce shock and/or vibration transmitted between the engine and the first motor-generator.

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.
