Estimating the term…
A force transmission device having a hydrodynamic component, disposed between an input and an output, comprising at least a pump shell and a turbine shell, forming an operating cavity in combination, with an actuatable clutch device for at least partially bridging the hydrodynamic component, comprising a clutch component for at least partially bridging the hydrodynamic component, comprising a first clutch component connected with the input and a second clutch component at least indirectly connected to the output, which can be brought into operative engagement with one another through an actuation device, with a vibration absorber disposed in the force flow at least subsequent to the actuatable clutch device, with a housing coupled with the input or with an element coupled non-rotatably to the input and coupled with the pump shell.
A combined power transmission and drive unit (1) for an application in hybrid systems (2) between at least a first engine (3) and an element to be driven, with a power transmission device (7) featuring or forming a start-up element (30) and an upstream-disposed, selectable clutch device (11) for selective disconnection/connection of the power flow between the first engine (3) and the power transmission device (7), comprising a first clutch part (11E) connectable with the first engine (3) and a second clutch part (11A) connected with an input (E) of the power transmission device (7), which can be actuated at least partially by a servo unit (12) activated hydraulic medium with at least a piston element (13) and a piston chamber (15) associated with the piston element (13) and that can be pressurized with hydraulic medium, wherein the piston chamber (15) pressurized with the hydraulic medium is disposed and executed such that the latter rotates with the rotation speed of the first clutch part (11E) or of an element connected non-rotatably with the latter.
A combined power transmission and drive unit (1) for an application in hybrid systems (2) between at least a first engine (3) and an element to be driven, with a power transmission device (7) featuring or forming a start-up element (30) and an upstream-disposed, selectable clutch device (11) for selective disconnection/connection of the power flow between the first engine (3) and the power transmission device (7), comprising a first clutch part (11E) connectable with the first engine (3) and a second clutch part (11A) connected with an input (E) of the power transmission device (7), which can be actuated at least partially by a servo unit (12) actuated with hydraulic-medium with at least a piston element (13), wherein, a means (34) for transmission of predefined torque between the first engine (3) and the power transmission unit (7) are provided, which are executed and disposed such that they are suitable to transmit full torque that can be developed by the first engine (3).
