摘要： The invention relates to a through-connection clutch, for transferring torque between a drive motor and a transmission of a motor vehicle, for example, having a friction clutch (2) which can be actuated and an engaging and disengaging form-fit clutch (3), wherein the form-fit clutch (3) is arranged radially within the friction clutch (2) and the friction clutch (2) and the form-fit clutch (3) can be actuated independently of each other. In order that the through-connection clutch requires as small an installation space as possible, can be flexibly actuated and is still cost-effective to produce and ensures low-wear yet safe and comfortable torque transmission in a drive train of a vehicle, according to the invention a pressure plate (10) of the friction clutch (2) and a form-fit element (12) of the form-fit clutch (3) are arranged concentrically, rotationally fixed among each other and movable against each other and can be actuated via an actuation unit (15) which is rotationally uncoupled from the pressure plate (10) and the form-fit element (12). Depending on the operating situation, the friction clutch (2) and/or the form-fit clutch (3) are selectively actuated one or more times to activate same.

摘要： The invention relates to a method for actuating a clutch (6) of a drivetrain of a motor vehicle, wherein, for a rolling movement of the motor vehicle on a downward slope when the throttle pedal is not actuated, and for a coasting movement of the motor vehicle on a flat surface when the throttle pedal is not actuated, a clutch position of the clutch (6) is determined as a function of a rotational speed difference between an input rotational speed of a transmission (2) of the drivetrain and an idle speed of a drive unit (1) of the drivetrain. According to the invention, the clutch position determined from the rotational speed difference between the transmission input rotational speed and the drive unit idle speed is corrected with at least one variable which is dependent on a vehicle acceleration.

摘要： The invention relates to a method for controlling an automated friction clutch (2), which is arranged in a drive train of a motor vehicle in the force flow between a drive motor (3) and a drive transmission (4), and which is designed so that it can be passively closed by means of spring pressure, disengaged and engaged by means of a controllable clutch actuator (14), and which comprises a travel sensor (24) for capturing the respective actuator travel (x_K) of the clutch actuator (14) or an associated transmission element (17), wherein during operation of the motor vehicle a current key point (x_K_Anl, x_K_Zu) of a torque characteristic (28) is determined for controlling the friction clutch (2) and used for the adaptation of said torque characteristic (28). In order to simplify an exact determination of key points for adaptation of the torque characteristic (28), it is provided that a plurality of values of the actuator travel (x_K) are captured with an engaged friction clutch (2) and disconnected clutch actuator (14) at predetermined intervals, and thus a current closed point (x_K_Zu) of the torque characteristic (28) that is close to the actual closed point is determined by calculation from said values, and the closed point is used to adapt the torque characteristic (28).

摘要： The invention concerns a device for actuating a diaphragm spring clutch (20) for vehicles by means of a pneumatic, hydraulic or electric actuator (24), comprising a controller connected upstream of the actuator (24), whose output control variable actuates the actuator (24). To compensate for the strong nonlinearity of the releasing force over the releasing stroke that is typical of diaphragm springs, a controller is used, whose characteristic curve is plotted in such a way that this nonlinear curve of the releasing force is at least approximately compensated via a correspondingly coordinated actuation of the actuator (24), so that it remains essentially identical over the releasing stroke.

摘要： The invention relates to a method for determining a torque characteristic of an automated friction clutch that is arranged in a drive train of a powered vehicle in the power stream between a drive engine (3) and a transmission (4) and engaged in the rest position, wherein at least two sampling points M_K1 (x_K1 ), M_K2(x_K2) of a grade-dependent torque characteristic M_K = f (x_K) are defined, of which at least one sampling point is determined at a slippage limit of the friction clutch (2). To simplify and speed up the determination of the torque characteristic M_K = f (x_K), a first sampling point M_K1 (x_K1) is determined with the clutch (2) engaged, transmission (4) in neutral and drive engine (3) running, by slowly releasing the clutch (2) further until a drop in the rotational speed of the incoming input shaft (10) of the transmission (4) relative to the rotational speed of the drive engine (3) is sensed, and then the corresponding variable pair M_K1, x_K1 of this sampling point is acquired with the known braking moment M_B of the input shaft (10) and the measured set position x_K(M_B), stored as a variable pair of the sampling point M_K1(x_K1) and subsequently used for adaptation of an existing characteristic M_K' = f (x_K).

摘要： The invention relates to a method for operating an automatic friction clutch. According to said method, a clutch load which corresponds to an energy input is determined and an operation mode of the clutch is controlled depending on the detected clutch load. According to the invention, to counteract glazing of the clutch linings due to an insufficient energy input, in relation to the slip operation time of the clutch, the clutch load is specifically increased, and to counteract premature wear, the clutch load is specifically reduced.

摘要： A method is proposed for controlling a through-connection clutch of a vehicle, in which an interlocking portion of the clutch is opened when the drive-train is virtually free from torque, a shifting operation is then carried out, and after the shifting operation the clutch is closed again. According to the invention, the torque transmitted by the interlocked connection in the clutch is influenced by controlling the motor in order to produce a torque-free condition at the interlocked connection in the clutch, in such manner that the interlocked connection is pre-stressed before the torque-free condition has been reached and separated immediately only when the torque-free condition is reached.
