  • Methods for the additive manufacture of components in layers, and corresponding computer program products
    Patent number: 11986995
    Abstract: The disclosure provides methods of additive manufacture of components in layers in a powder bed by at least two laser beams that can be deflected two-dimensionally over the same powder bed region. Each laser focal spot is projected onto the power bed and is or is set to a diameter of less than or equal to 300 ?m. Components to be produced in the powder bed region are manufactured by each of the laser beams, and each individual surface contour of the component is manufactured solely by one of the laser beams.

  • Actuation device for a dual clutch transmission
    Patent number: 8485333
    Abstract: A dual clutch actuation device generates the axial compression force required to compress a first and second set of frictional elements of a dual clutch module. Dual clutch actuation device includes a first and second annular piston. The annular pistons include a first end that is in contact with annular bearing assemblies. The annular bearing assemblies are in contact with actuation levers that are in contact with the first set of frictional elements. The annular pistons are arranged in concentric annular piston slots. Together the piston and annular slots form annular piston chambers. The piston chambers are filled with hydraulic fluid. When the hydraulic fluid is pressurized the pistons slide out of the annular slots and apply a force on the actuation levers which in turn apply an axial compression force on the frictional elements.
