摘要:
A double clutch transmission with two clutches connected to a drive shaft and to one of two transmission input shafts. Fixed gears are coupled to the input shafts and engage idler gears. Several coupling devices connect the idler gears to a countershaft which have an output gear that couples to an output shaft such that forward and reverse gears can be shifted. Two dual gear planes each comprising two idler gears, each supported by a respective countershaft, and one fixed gear. In each dual gear plane, at least one idler gear wheel can be used for at least two gears. Two single gear planes each comprise an idler and a fixed gear such that a winding-path gear is shifted by disengaging an output gear wheel coupling device on the first countershaft. Another winding-path gear is shifted by disengaging an output gear wheel coupling device on the second countershaft.

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).

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:
Described is a method for controlling and regulating a drive train of a vehicle comprising one drive unit, one transmission and one output unit. The transmission has controllable free-wheel device corresponding with toothed wheel pairs for disconnecting or connecting an old or a new gear and located on the input side one clutch. In the presence of a shifting signal for carrying out a higher traction shift, an input torque of the drive unit is quickly reduced so that a first vibration is induced in the drive unit. During a subsequent shifting, an operative connection is abruptly created between a free-wheel device and a toothed wheel pair corresponding therewith in a manner such that a second vibration counteracting the first vibration is produced in the drive train. With the engagement of the new gear the operative connection of the old gear is canceled as a result of a torque reversal from a pull torque to a push torque.
