  • Publication number: 20180231067
    Abstract: A clutch device includes a first and a second input side as well as a first and a second output side. The input sides and the output sides can be rotated about a common axis of rotation. The clutch device furthermore includes a first clutch between the first input side and the first output side and a second clutch between the first input side and the second output side. A third clutch may be provided between the first input side and the second input side. A first hydraulic actuating device is associated with the first clutch, a second hydraulic actuating device is associated with the second clutch, and a third hydraulic actuating device is associated with the third clutch. A radial flange, which receives an axial actuating force of one of the actuating devices, includes a radially extending feed for hydraulic fluid to one of the actuating devices.

  • Patent number: 8388483
    Abstract: A differential gearbox including a disk on the input side, a first drive part that is non-rotatably connected to a first driven axle, and a second drive part that is non-rotatably connected to a second driven axle. A planetary gear arrangement is provided between the first drive part and the second drive part for transmitting torque from the disk on the input side to the first drive part and the second drive part. The first drive part is a first drive disk and includes a concavity radially outwardly of the first driven axle. The second drive part is a second drive disk extending radially outwardly of the second driven axle. The concavity is directed away from the second drive disk. The planetary gear arrangement is disposed in a space that is formed by the concavity of the first drive disk and the opposing region of the second drive disk.

  • Patent number: 7131921
    Abstract: A continuously variable transmission having two pairs of conical disks operatively connected by an endless torque-transmitting belt. One of each of the disk pairs is axially movable relative to the other along a supporting shaft. The movable disk includes an inner tooth system that engages with an outer tooth system formed on the supporting shaft. The internal tooth system can be produced by a broaching process. The inner tooth system extends outwardly of the conical disk.

  • Publication number: 20050288136
    Abstract: A fixed pulley assembly for a belt-driven conical-pulley transmission contains a fixed pulley rigidly connected to an input shaft, a drive shaft, a friction clutch having an input element connected in a rotationally fixed manner to the drive shaft, an output element that can be brought into frictional engagement with the input element, and a torque sensing device operating between the output element and the fixed pulley, having a spreading surface that is rigidly connected to the fixed pulley and a sensing element that moves axially relative to the fixed pulley. The output element of the friction clutch is positioned on the side of the fixed pulley facing away from the conical surface and rotatably mounted coaxially to the input shaft. The sensing element is guided on an outer circumferential surface of the output element so that it is axially movable and is immovable in the circumferential direction.
