    摘要: A method for operating a parallel hybrid powertrain (1) of a motor vehicle with multiple drive units (2, 3) and with a single output side (5) is described. At least one internal combustion engine (2) and one electric motor (3) are provided and the at least one electric motor (3) is arranged in the powertrain between the output (5) and the at least one internal combustion engine (2). A first friction-locking shifting element (7) is provided between the internal combustion engine (2) and the electric motor (3), while a coupling element (8A) with rotational speed dependent recognition and at least one second friction-locking shifting element (30) are arranged between the electric motor (3) and the output side (5). A target output torque to be applied at the output (5) is a function of the power transmission capacity of the second shifting element (30). The power transmission capacity of the second shifting element (30) is controlled as a function of the required target output torque (m_fahr_soll) so that the second shifting element (30) has the power transmission capacity required for achieving the target output torque (m_fahr_soll) at the output (5). A target slip specification (s_30_soll) of the second shifting element (30) is controlled at least as a function of the target-drive torque by means of the target drive torque (m_2_soll, m_3_soll) to be produced and are converted with a closed loop control as a function of a further operating state parameter of the parallel hybrid powertrain by the drive units (2, 3).

    摘要: A device (1) for transmitting torque from a first shaft (2) to a second shaft (3) of a transmission device, in particular a counter shaft transmission. The device (1) has a first gear (5) supported on the first shaft (2) by a bearing device (4) and which, in an assembled state, engages a second gear (6) arranged on the second shaft (3). The first gear (5) can be shifted into an activated state in which the first gear is connected in a rotationally fixed manner to the first shaft (2). A supporting mechanism (18) is associated with the first gear (5), next to the bearing device (4), via which tilting moments present and acting on the first gear (5), at least in a connected state, are transmitted to and supported by the first shaft (2).

    摘要: A transmission is described, in particular an automatic transmission for a vehicle, having at least one shift control element formed at least of a second shift control element half that can be brought into active frictional engagement with a first shift control element half. The shift control element halves can be connected to non-rotating and rotating transmission components, and a positive-locking coupling device is provided at least between the first shift control element half and the transmission components that can be connected thereto. The coupling device also comprises a synchromesh device. In addition, a method is described for controlling a transmission that has at least one shift control element and two shift control element halves which can be brought into active frictional engagement. When it is necessary to close the shift control element, the coupling device is synchronized by a synchromesh device, a positive-locking function of the coupling device is closed, and the halves of the shift control element are frictionally engaged.

    摘要: A process for controlling and regulating a clutch in a stepped load switchable automatic transmission for a motor vehicle where an electronic control device determines the behavior of the clutch during three operating conditions by way of a first or a second control circuit, and that a shift from a first into a second gear ratio stage takes place. In accordance with the invention, the first control circuit is used for controlling and regulating the clutch during the first operating condition, whose controlled variable is equivalent to the actual value of the engine speed (n_MOT_IST). During the second driving condition, a second control circuit is used, whose controlled variable is equivalent to the actual value of a differential rotational speed (dnK_IST) of the clutch, and during the third operating condition, the clutch is impinged with a controlled pressure value dependent upon various influence magnitudes.
