Abstract
Dual-mass flywheel concept for internal combustion engines, where the secondary flywheel (3) can be disconnected and reconnected as required, by means of a clutch (6). The concept is characterized in that it comprises a primary flywheel (2) fixedly mounted on the engine (1) crankshaft, a secondary flywheel (3) which is stored so that it can rotate freely, a clutch (6) connecting the secondary flywheel to the drive shaft (5) (input shaft on the gearbox (9)), an elastic element (4) (springs) which connects the primary flywheel to the drive shaft.
Claims13
A system for automated gear shifting of a manual transmission comprising, an internal combustion engine, a primary flywheel mounted on a crankshaft, an elastic member that connects the primary flywheel to a drive shaft, a second flywheel, a clutch for connecting the secondary flywheel to the drive shaft, wherein a first electric motor/generator is connected to the primary flywheel and a second electric motor/generator is connected to the secondary flywheel, the secondary flywheel is disengaged from the drive shaft when the speed exceeds 1.5-4 times the combustion engine idling speed.

8-12. (canceled)
A method for automated gear shifting of a manual transmission having an internal combustion engine, a primary flywheel mounted on a crankshaft, an elastic member for connecting the primary flywheel to a drive shaft, a second flywheel, a clutch for connecting the secondary flywheel to the drive shaft, a first electric motor connected to the primary flywheel, and a second electric motor connected to the secondary flywheel, the method comprising:
- engaging the secondary flywheel to the driveshaft in response to a specified engine revolution speed, the specified engine revolution speed being in the range of 1.5 to 4.0 times an idle engine revolution speed;
- and
- in response to the engine revolution speed exceeding the specified engine revolution speed, disengaging the secondary flywheel from the driveshaft.
