  • Patent number: 11339862
    Abstract: A method for operating a drive-train of a motor vehicle. The drive-train having a transmission connected between a drive aggregate and a drive output. A hydrodynamic starting element is connected between the drive aggregate and transmission. The starting element includes a converter and converter lock-up clutch. A Power Take-Off (PTO) can be coupled to the drive aggregate on the drive aggregate side to take up drive torque delivered by the drive aggregate. In order to determine the torque taken up by the PTO, the lock-up clutch is operated in a rotational-speed-regulated manner at least when the PTO is coupled to the drive aggregate in order to set a defined target slip at the lock-up clutch. As a function of the actuation pressure of the lock-up clutch required for setting the target slip when the PTO is coupled, the torque taken up by the PTO is determined.

  • Patent number: 10205293
    Abstract: The invention relates to a commutator, comprising an insulating base and a plurality of commutator segments arranged on the insulating base, wherein each commutator segment comprises a metal layer, a transition layer and a graphite layer arranged on the base in sequence. The transition layer contains a material identical to that of the graphite layer and a material identical to that of the metal layer. The invention further relates to a motor comprising the commutator and a method for manufacturing the commutator. As the transition layer contains the material identical to that of the graphite layer and the metal layer, the problem that the graphite layer and the metal layer are cracked during high temperature sintering is resolved. The service life of the commutator is prolonged. The method for manufacturing the commutator reduces chemical contamination and production cost caused by electroplating and brazing used in a traditional technology.
