Embodiment Construction

[0035] Preferred embodiments of the present invention will be described in detail below.

[0036]

[0037] The inventors of the present invention have found that, in a sliding member having a plurality of sliding parts, by arranging a lubricant that substantially does not contain conductive carbon or contains a small amount of conductive carbon on the sliding part that has a filling port, and that there is no filling The sliding part of the mouth is equipped with a lubricant containing a larger amount of conductive carbon than the aforementioned lubricant, so that the destaticization of the sliding member and the product (such as an automobile) on which the sliding member is mounted can be improved and / or the static electricity brought by the destaticization can be improved. Excellent handling stability and the ability to easily distinguish between old and new lubricants when refilling. One aspect of the invention therefore relates to a sliding member.

Abstract

One aspect of the invention 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.

Description

technical field [0001] The present invention relates to sliding members. [0002] technical background [0003] The body of the car is usually positively charged due to friction and bumps between the tires and the road surface generated by driving. Radio frequency noise generated when the charged static electricity is discharged may cause malfunctions in electronic equipment mounted in automobiles. For this reason, a technology has been developed in which conductive grease is sealed in the wheel bearings to eliminate static electricity through the wheel bearings. [0004] For example, Japanese Patent Application Laid-Open No. 2004-169862 describes a wheel bearing for automobiles, which is characterized in that it comprises: an outer track wheel having a hub track on the inner peripheral surface, an inner track wheel having an inner ring track on the outer peripheral surface, and an inner track wheel between the hub track and the inner track. A plurality of rolling elements ...
