  • Patent number: 8550951
    Abstract: A differential comprising at least one drive wheel, at least two axle wheels, at least one compensating wheel and at least one connecting element, wherein the connecting element experiences at least a first torque at least from the drive wheel, and wherein the connecting element transmits at least a second torque to at least one of the at least two axle wheels. The drive wheel is constructed such that the drive wheel at least partially surrounds at least one inner chamber; the connecting element is arranged at least partially inside the inner chamber that is at least partially surrounded by the drive wheel, and the connecting element is constructed in one piece.
    Type: Grant

  • Patent number: 8360921
    Abstract: A differential, having at least one drive gear, at least two axle gears, at least one compensating gear, and at least one connector element, in which the connector element is subjected to at least one first torque from the drive gear and transmits at least one second torque to at least one of the at least two axle gears. The drive gear is constructed in such a manner that the drive gear at least partially encloses at least one interior space, and the connector element is arranged at least partially inside the interior space enclosed at least partially by the drive gear.

  • Patent number: 8342146
    Abstract: A camshaft assembly, particularly for use in an internal combustion engine, having a shaft base body and a plurality of cam parts. In order to be able to selectively shut down individual cylinders, cam parts are provided with cams which are arranged so as to be rotationally fixed and axially displaceable in relation to the shaft base body. Depending on a desired sequence of axially fixed and axially displaceable cam parts, it is proposed to arrange the axially displaceable cam parts on a longitudinally extending profile in an axially displaceable manner and to push the axially fixed cam parts—insofar as these are necesary—over or across the receiving area for the axially displaceable cam parts and to secure them to the shaft.

  • Patent number: 8267006
    Abstract: An axial piston intended for an axial piston machine and comprised of at least two components forming a driving part and a compressing part. To enable manufacture of the axial piston in an easy and inexpensive way while simultaneously reducing the weight, the components are manufactured by a solid forming process and joined together by a capacitor discharge welding process.
