  • Patent number: 9109638
    Abstract: A switchable coupling, in particular for vehicle auxiliary assemblies, is provided. The coupling includes an actuating system actuated electrically, mechanically, pneumatically or hydraulically between a driving element and an output element, and a switching element movable between switching start and end positions counter to the force of one or more resetting elements upon actuation of the actuating system. In the end position, the switching element connects the driving and output elements such that the output element and an auxiliary coupling connected thereto rotate with the driving element. After deactuation, locking bodies located on the auxiliary coupling produce an connection between the driving and output elements which continues to conduct torque between the driving and output elements. The connection is interrupted only when the rotational speed of the driving element falls below a limit value. The coupling does not require a permanent supply of power in the open or closed state.

  • Patent number: 9038797
    Abstract: A switchable coupling with a coupling system between a driving element and an output element is provided. The switchable coupling includes an actuator, an elastic actuating element and a switching element movable between starting, central and end positions. In the central position the switchable coupling has a different state (open or closed) than in the starting position. The switchable coupling further includes a bolt constrained between first and second bolt stops. Axial movement of the switching element causes operative surfaces connected to the switching element or the bolt to engage with elements on other of the switching element and the bolt, such that the bolt rotates relative to the switching element. The bolt alternately moves relative to the switching element into a first relative position blocking switching element movement in the central position, and into a second relative position permitting movement of the switching element toward the starting position.

  • Patent number: 8133144
    Abstract: A planetary transmission having a continuously variable transmission ratio. The transmission includes two sun wheels having sun wheel circumferential surfaces, and that are axially spaced and rotatable independently of each other around the same axis of rotation. A ring wheel is situated on the same axis as the sun wheels and has an internal circumferential surface. Planet wheels are provided having planet wheel circumferential surfaces that are in frictional contact with the internal circumferential surface of the ring wheel and the sun wheel circumferential surfaces. A web element is also provided, and the planet wheels are each rotatable about an associated planet wheel axle, which is guided in the web element so that it is movable in the radial direction relative to the transmission longitudinal axis.

  • Patent number: 7819772
    Abstract: A powershiftable multistage transmission (LMG) between an input shaft (an), which can be connected to a first transmission shaft (1), and an output shaft (ab=2) as a second transmission shaft, comprising two shaft-lines (WS1 and WS2) which are arranged in parallel in a transmission housing (0), three transfer gears (SG) between these shaft-lines, three planetary gears (PG) each with a sun gear (So), a ring gear (Ho) and a planet-carrier (Pt) with single planets, and a plurality, preferably five, shifting elements (SE). With only five shifting elements eight forward gears and one reverse gear can be switched. The six gear elements have ratios which can be designed easily even if the total ratio range is somewhere between 7<?ges<9. Due to the distribution of the gear elements on two shaft-lines, the transmission gearbox has a short length and is suitable for front-cross-applications as well as inline-applications. All shifting elements can be easily fed with oil to control them.
