Through-connection clutch and method for the actuation thereof

摘要

A through-connection clutch, for transferring torque between a motor and transmission of a vehicle, which has a friction clutch and a form-locking clutch. The form-locking clutch is disposed radially within the friction clutch, and the clutches can be actuated independently of each other. To minimize the required installation space, the through-connection clutch can be activated flexibly, but is still inexpensive to produce and ensures low-wear yet safe and comfortable torque transfer in a drive train of a vehicle. A pressure plate of the friction clutch and a form-locking element of the form-locking clutch are concentric, rotationally fixed together, and movable toward one another, and can be actuated via an actuation unit, which is rotationally decoupled from the pressure plate and the form-locking element. Depending on the operating situation, the friction clutch and/or the form-locking clutch is selectively activated one or more times.
