Hybrid transmission with regenerative braking - has electric motor-generator with flywheel driven via control clutch to serve as regenerative brake

摘要

The hybrid transmission has a motor generator as the drive unit, coupled to a large flywheel. The motor generator is driven from the engine via a control clutch and can serve as a regenerative brake on overun. A relatively small power unit is required, with any torque peak demands met from the battery. The flywheel allows large amounts of torque to be stored in a small braking distance, rather than rely on the charge rate of the accumulator. The system provides flexible control of torque with a low fuel consumption and minimum exhaust emission.
