Embodiment 1
[0107] In the lubricant of Example 1, the content of the thickener was changed to 3% by mass, the content of carbon black was changed to 5% by mass, the content of PTFE was changed to 10% by mass, the content of other additives was changed to 1.8% by mass, The lubricant of Example 2 was prepared under the same conditions as above except that the content of the base oil was changed to the balance. Using the lubricant of Example 2, a test vehicle was prepared under the same conditions as above.
[0108] The test vehicles of Example 2 and Comparative Example 1 were driven at a speed of about 100 km / h from the start. During driving, use a non-contact surface potential measuring device (which can measure the surface potential of the positive and negative electrodes in the range of 0.1 to 5kV) to measure the potential of the tire tread in the rear of the left rear wheel and the fender inner liner (with the tire tread). The potential of the facing part). The change over time of the...

Abstract
Disclosed is an automotive slide member including a first slide portion having a first lubricant applied between first portions of a first friction slide mechanism, and a second slide portion having a second lubricant applied between second portions of a second friction slide mechanism. The first slide portion is arranged at a part to be touched by an operator who attaches the automotive slide member to an automobile or a user of the automobile. The second slide portion is arranged at a part that is not touched by the operator who attaches the automotive slide member to the automobile or the user of the automobile. The second lubricant contains a relatively larger amount of conductive carbon than that of the first lubricant.
Description
technical field [0001] The present invention relates to a sliding member for automobiles. [0002] technical background [0003] The body of the car is usually positively charged due to the friction and noise 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...
