  • Wheel hub drive
    Patent number: 11220174
    Abstract: A wheel hub drive as a direct drive of a wheel of a vehicle having an electric motor preferably designed as a permanent-magnet synchronous motor (PMSM)—external rotor motor—which is substantially arranged in the region within the wheel, wherein a rotating part of a friction brake is frictionally, interlockingly, and/or integrally connected to the motor for braking. The rotating part is operatively connected to the rotor of the motor, directly or indirectly, from outside of the motor.
    Type: Grant
    Filed: July 7, 2017
    Date of Patent: January 11, 2022

  • Silicon-carbide sintered abrasive grain and process for its production
    Patent number: 5756409
    Abstract: Abrasive grain with significantly improved toughness is obtained by pressureless sintering of .alpha.-silicon carbide powder with oxidic sinter additives, especially aluminum oxide/yttrium oxide, which is also suitable for those applications where an ordinary silicon carbide abrasive grain is too brittle.
