  • Patent number: 10955049
    Abstract: Dual-mass flywheel concept for internal combustion engines, where the secondary flywheel can be disconnected and reconnected as required, by means of a clutch. The concept is characterized in that it comprises a primary flywheel fixedly mounted on the engine crankshaft, a secondary flywheel which is stored so that it can rotate freely, a clutch connecting the secondary flywheel to the drive shaft (input shaft on the gearbox), an elastic element (springs) which connects the primary flywheel to the drive shaft.
    Type: Grant

    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.

  • Patent number: 10024406
    Abstract: An actuator converting a rotary movement into a linear movement is disclosed. The actuator includes a drive means (11), a primary low friction screw mechanism (3, 6, 14) driven by the drive means, a secondary traditional screw mechanism (7, 13) which is connected to the primary screw mechanism and moved linearly by this. The secondary screw mechanism transfers the linear movement to a driven means, such as a clutch. The primary screw mechanism is performing the working stroke proper, while the secondary screw mechanism is arranged to compensate for changes in the engagement point of the driven means. One of the screw mechanisms is provided with a spring (4) making the actuator self-regulating.
