  • Patent number: 11725158
    Abstract: A grease composition is intended primarily for use in constant velocity joints (CV joints), especially ball joints and/or tripod joints, which are used in the driveline of motor vehicles. The grease composition for use in constant velocity joints comprises at least one base oil, at least one thickener, zinc sulfide, as well as molybdenum disulfide and/or tungsten disulfide. Further, a constant velocity joint comprises the grease composition.
    Type: Grant
    Filed: September 18, 2019
    Date of Patent: August 15, 2023
    Assignee: GKN Driveline International GmbH
    Inventors: Jisheng E, Christoph Lindlahr, Mario Witzdam
  • Patent number: 11643613
    Abstract: A grease composition is intended primarily for use in constant velocity joins (CV joints), especially ball joints and/or tripod joints, which are used in the drivelines of motor vehicles. The grease composition for use in constant velocity joints comprises at least one base oil, and least one thickener, at least one copper sulfide in an amount of approximately 0.01 wt-% up to approximately 1.5 wt-% of the grease composition, molybdenum disulfide and/or at least one phosphorus-free organic molybdenum complex in an amount of approximately 0.1 wt-% up to approximately 5.0 wt-% of the grease composition. Further, a constant velocity joint comprises the grease composition.

  • Publication number: 20110021391
    Abstract: A grease composition which has a good compatibility with boots made of rubber or thermoplastic elastomer, and which also gives enhanced endurance, low wear and low friction in use in constant velocity joints is disclosed. A grease composition is suggested comprising a) at least one base oil; b) 5% by weight to 40% by weight of at least one calcium sulphonate soap and/or calcium sulphonate complex soap as a thickener; and c) at least one molybdenum containing additive.
