  • Patent number: 8869963
    Abstract: An arrangement for shifting a gearbox. The arrangement having first and second transmission components (14) and an axially movable shifting sleeve (17) such that the shifting sleeve (17) and the second transmission component (14) each have respective drive teeth (14a, 17a) that can be brought into engagement with one another. The drive teeth are in the form of beveloid teeth (14a, 17a).
    Type: Grant

  • Patent number: 5194056
    Abstract: In an automatic transmission (1) for motor vehicles with a reduced planetary linkage, whose planet gears (9 and 10) mesh with each other and share a common carrier (11), whose sun gear corotationally mounted on a hollow shaft (4) as well as whose sun gear (13) corotationally mounted on an intermediate shaft can be selectively connected via clutches (3 and 5) with an input shaft, whereby the intermediate shaft (6) can be selectively braked via a first friction brake (16) and a ring gear of the planetary linkage is connected with the driven gear (15) of the automatic transmission (1), a clearly structured design has to be created with simultaneous reduction of construction expeditures. For this purpose, the intermediate shaft (6) is built as a central solid shaft which protrudes beyond the driven gear (15) on the transmission-output side and the first friction brake (16) engages this segment.
