  • Patent number: 11912956
    Abstract: One aspect of the disclosure relates to a sliding member. The sliding member includes: a first sliding portion having a first lubricant placed between first parts of a first friction sliding mechanism; and a second sliding portion having a second lubricant placed between second parts of a second friction sliding mechanism. The first sliding portion has a lubricant feed port from which the first lubricant is fed, and the second sliding portion has no lubricant feed port from which the second lubricant is fed. The first lubricant contains base oil and an additive. The second lubricant contains base oil and an additive containing conductive carbon. The second lubricant contains a relatively larger amount of conductive carbon than the first lubricant.

  • Publication number: 20230304632
    Abstract: In a vehicle having a microscopic dynamics friction mechanism formed of at least two parts and charged to a positive potential due to traveling, a lubricant in which first additive fine particles made of a resin that generates a negative potential are uniformly mixed with an electrically insulating base oil is disposed in a clearance between members of the friction mechanism. While the first additive fine particles are in frictional contact with the member, neutralization and elimination of the positive potential of the member are started. The first additive fine particles are attracted by a Coulomb force to the positive potential of the surface of the member other than a frictional contact part of the member when floating in the electrically insulating base oil and moving and circulating. The neutralization and elimination of the positive potential of the member are continued.
