  • Patent number: 10935056
    Abstract: An electromagnetic valve for a hydraulic system for an automatic transmission of a vehicle. An armature chamber is filled with hydraulic medium and fluidically connected to hydraulic lines of the hydraulic system. An armature is mounted in the armature chamber such that its stroke is adjustable. The armature includes a shut-off body and divides the armature chamber into an opening-side chamber facing the flow opening and into an inner chamber facing away from the flow opening. During a stroke of the armature, an oil exchange occurs, and a displacement volume of the hydraulic medium overflows from the opening-side chamber into the inner chamber. A hydraulic line leading to the opening-side chamber or to the inner chamber of the armature chamber includes a dirt collecting element that is designed as a permanent magnet and that retains contaminations in the hydraulic medium that flows through the hydraulic line during an oil exchange.

  • Patent number: 10071624
    Abstract: A drive device for a motor vehicle includes a primary powertrain and a secondary powertrain, wherein the primary powertrain includes a combustion engine for generating a total torque; a torque distribution device coupled to the combustion engine and including a first and a second output, wherein the torque distribution device is designed to provide a first partial torque in mechanical form at its first output derived from the total torque, and to provide a second partial torque in electrical form at its second output derived from the total torque; and a transmission which is coupled to the first output of the torque distribution device; wherein the secondary powertrain includes an electric machine which is coupled to the second output of the torque distribution device; wherein the torque distribution device includes a torque limiting device which is designed to limit the first partial torque to a presettable threshold value.

  • Publication number: 20130279734
    Abstract: An acoustic transducer assembly with a basket for receiving and electrically contacting an acoustic transducer, the basket being configured to be mounted on, and electrically connected to, a platform, such as a printed circuit board, or a support or a housing. The basket may include electrical contact areas for electrically connecting the basket to the platform, and at least one mounting structure for cooperating with a platform-sided mounting structure to form a fixed mechanical connection with the platform. An electrical contact area of the basket may be integrally formed with the mounting structure of the basket.
