  • Patent number: 8573376
    Abstract: A motor vehicle gearbox having a hydrodynamic retarder (12) and at least one connection (23) for a power take-off drive. The retarder (12) can be driven by an output shaft (5) of the gearbox (1) via a spur gear stage (11) having a drive gear (9) and an output gear (10). The drive gear (9) engages with at least one further output gear (13) by which at least one further power take-off drive (17, 21) can be driven.
    Type: Grant

  • Patent number: 7249810
    Abstract: A stepped braking system is used as a function of the required braking torque in this method for maintaining a desired braking torque in a vehicle equipped with stepped and infinitely-variable permanent braking systems whereby simultaneous activation of the stepped and infinitely-variable braking systems occurs in such manner that the sum of the participations of the different systems provides the required braking torque at any time.

  • Patent number: 4807489
    Abstract: A gear shift device e.g. for a six-speed automotive speed change transmission with a gear shift lever for selection and shifting of all gears and with shift rails for the shifting of gears in one shift path has an H-shaped shift pattern similar to a four-speed transmission and has means for fixing or returning of a central selection and shift shaft or rotating shaft and/or the gear-shift lever into predetermined shift paths, e.g. the gears 3/4, where for the shift path of the gears 5/6 a retention device is provided additionally, which upon completed or nearly completed shift into the next higher, that is sixth gear, retains the central selection and shift shaft or the rotating shaft and/or the gear-shift lever in this shift path and upon completed or nearly completed shift into the next lower, that is fifth gear, permits the return of the central selector and shift shaft or the rotating shaft and/or the gear-shift lever into a lower shift path, e.g.

  • Patent number: 4336683
    Abstract: A mechanism for the production of wrapped yarn which consists of a bundle of spun fibers wrapped around a binding thread. A hollow spindle 5 is supported between a pair of delivery rolls 1, 2 and a pair of draw-off rolls 3, 4. A rotating binding thread bobbin 7 is arranged coaxially with the hollow spindle 5 and is enclosed by a housing 8. An air flow which can be generated in the housing and/or introduced into the housing causes the pressure within the housing to be built up so as to prevent fibers and the like from entering an exit hole carried in a cover 80 provided on the housing.

  • Patent number: 4254615
    Abstract: A device for controlling the bobbin drive of a flyer roving frame which has a bobbin, a flyer and drive roll thereon that are utilized for building a bobbin with yarn. A drive for the frame incorporating a differential gear and controls are provided for adjusting the driving speed of the flyer and drive roll stepwise to different rotational speed stages during the building of the bobbin. An additional speed adjusting device is provided for automatically varying the driving speed of the bobbin within each rotational speed stage. A switching device is provided for automatically switching the rotational speed stages.
