A dual clutch transmission () includes a breather assembly () with a breather element (). The breather element () includes at least one entry opening () facing a transmission interior and an outwardly facing exit opening (). The breather assembly () also includes at least one oil collection element () arranged between the breather element () and an oil spray source ().

Transmission

A triple clutch arrangement and a powertrain for a motor vehicle with a dual clutch transmission for use between at least two drive devices and the dual clutch transmission. A first clutch and a second clutch of the triple clutch arrangement are connectable to the first drive device and in each instance to a transmission input shaft. The first drive device and the second drive device are both connected to, or connectable to, a primary side of the first clutch and/or the second clutch via the third clutch.

Triple clutch assembly, powertrain, and motor vehicle

The disclosure relates to a disk () for a disk clutch () comprising an annular base element () which has a toothing () with multiple teeth () for achieving a rotary driving engagement with a disk carrier (), wherein the base element () has at least one hardened region () in which the base element () is designed as harder than in the tooth flank regions () of the teeth (). In addition, the disclosure relates to a disk clutch () with such a disk (), a double clutch device () with such a disk clutch (), and a method for producing such a disk ().

Disk, disk clutch with such a disk, double clutch device with such a disk clutch, and method for producing a disk

An arrangement of a disk spring () at a piston () of a shifting element () in which the fingers of the disk spring () protrude through crests in the housing () and abut against a sheet metal sleeve () which is held in the housing () of the shifting element (). The disk spring () is configured as a closed ring and the outer diameter () of the disk spring () abuts against the piston () of the shifting element ().

Arrangement of a disk spring at a piston of a switching element

A disk clutch or brake, with inner and outer disk carriers that respectively carry inner and outer disks. The inner and outer disks are arranged axially in alternation next to one another. At least one of the inner and outer disk carriers have radial openings through which coolant flows toward the disks. The inner and/or outer disk carrier have a toothed component, which is fixed to and at least partially axially and radially encompasses a basic component. The inner or outer disks are fixed toothed component to prevent relative rotation while allowing axial displacement. Radial openings are formed in the basic and toothed components to enable a flow of coolant.

Disk clutch or multiple disk brake comprising a multi-part disk carrier

A differential piston (), designed as an annular piston, having pressure chambers () with at least one of the pressure chambers () being pressurized from radially inside the differential piston (), via a hollow shaft () or another radially inner element (), such as, part of a (cylinder) housing element () and a radial pressure medium-guiding channel () arranged directly within the differential piston (), such that only a single additional sealing element () is required.
