  • Patent number: 10766350
    Abstract: A transmission for a motor vehicle having an input shaft, an output shaft, a plurality of planetary gear sets, a plurality of shift elements, and an electric machine arranged axially parallel to the input shaft and operatively connected to the input shaft with a constant transmission ratio via a spur gear drive or a flexible traction drive mechanism. Various gear steps are formable between the input shaft and the output shaft through the planetary gear sets by selectively engaging shift elements of the plurality of shift elements. An actuating element of one of the plurality of shift elements is arranged, at least partially, radially within an element of the spur gear drive or the flexible traction drive mechanism arranged coaxially to the input shaft, and together with the spur gear drive or the flexible traction drive mechanism in a plane orthogonal to an axis of rotation of the input shaft.

  • Publication number: 20200256774
    Abstract: The invention relates to a method for determining elastic properties of a test body (1) by means of tensile or compressive loading in a test stand, wherein a center of gravity line (2) is defined for a longitudinal axis for the test body, said center of gravity line miming through elastic centers of gravity of infinitesimally thick discs which lie orthogonally to the longitudinal axis and into which the test body can be divided. The test body is clamped at two clamping points by means of clamping devices (13, 13?), and a force is introduced at at least one of the two clamping points in the direction of the respective other clamping point such that a line of action of a force introduced at at least one of the clamping points is substantially parallel to a connection line between the two clamping points.

    Abstract: A countershaft-type dual clutch transmission for a vehicle has two clutches having input sides connected to a driveshaft (AN) and output sides connected respectively to one of two transmission input shafts arranged coaxial to a mainshaft axis. A sub-transmission is associated in each instance with the transmission input shafts, at least two countershafts, a plurality of gear planes to which are assigned gear ratio steps, and at least one output shaft which can be connected to the sub-transmissions via an output gear plane. Only six gear planes with at least nine assigned gear ratio steps can be realized via only four double shift elements and at least one single shift element. Each countershaft can be coupled with four gear ratio steps via double shift elements, and one of the transmission input shafts can be coupled with a gear ratio step via a single shift element.

    Abstract: A dual clutch transmission designed as a reduction gearing which has concentric central and hollow transmission shafts, exactly one layshaft, and two power shift elements. A hollow shaft is provided coaxially on the layshaft, which can be rotatably fixed to the layshaft, via one shift device, and to which at least two gears of the gear stages are rotatably fixed. A further hollow shaft is provided coaxially on either the central or the hollow transmission shaft, which can be connected, via one of the shift devices, with the central or the hollow transmission shaft and to which at least two further gears of the gear stages are rotatably fixed. At least three transmission ratios are obtainable as a result of engaging the shift element into the power flow in three of the gear stages, by which one transmission ratio results from engaging only one shift element into the power flow.
