して考えられている。 The so-called linear motor, which has been developed in recent years as a method of entrusting the drive of the traveling body to the magnetic action between the traveling body and the ground side track equipment, or the method of entrusting the support and guidance of the traveling body to the magnetic action, has recently been developed. Induction-repulsion type magnetic levitation and attraction type magnetic levitation have been significantly developed, but the linear motor system called the on-vehicle primary type, and attraction type magnetic levitation require power feeding equipment from the ground along the track, and In magnetic levitation, whether by induced repulsion or attraction, the source of the magnetic field must be on the traveling body side, and a sliding device must be provided as an auxiliary means when supporting force and guiding force cannot be obtained magnetically. is considered to be an advantage in terms of its structure as a means of transportation.

いつた悪影響を生じる。 The present applicant has already filed an application for a structure that can be used as both a sliding track and electric ground equipment as Japanese Patent Application No. 1983-27426, entitled "Traveling Machine for Both Running and Feeding." The sliding track sheet material used for these purposes is molybdenum (Mo) or tungsten (W) provided on the traveling body side.
Copper-based sliding bearing materials or similar materials are used in combination with sliding shoes whose main components are
However, as is well known, because these have good conductivity, as mentioned above, the source of the magnetic field is on the traveling body side, and due to the structure of the transportation vehicle, it is difficult to be affected by this magnetic field. In a situation where it is not possible to lay a sliding track sheet on the ground, eddy currents are generated in the track sheet made of the above-mentioned materials due to the influence of the movement of the magnetic field due to running, and as a result, the interaction with the above-mentioned moving magnetic field is generated. This causes negative effects such as the generation of so-called magnetic drag, that is, an increase in the power consumption for running due to an increase in running resistance, and an increase in the temperature of the track sheet.
