The invention provides a side bearing. The side bearing comprises a side bearing pedestal, a roller shaft, a roller and a rubber spring, wherein the side bearing pedestal comprises a bottom plate, a first supporting plate and a second supporting plate; the first supporting plate and the second supporting plate are arranged at intervals in the lengthwise direction of the bottom plate and are fixedly connected with the upper surface of the bottom plate; a first mounting hole is formed in the first supporting plate; a second mounting hole is formed in the second supporting plate; a first end of the roller shaft is fixed in the first mounting hole; a second end of the roller shaft is fixed in the second mounting hole; the roller is fixed on the roller shaft; and the rubber spring is fixed under the bottom plate. Through the contact between the rollers and the side bearings on a train, the friction between the side bearings is transformed into sliding friction, so that the friction force is reduced, and the stability of a friction coefficient is guaranteed; the rubber spring enables the side bearing pedestal to move in the vertical direction, so that the performance of the train passing through a curve is further enhanced, and the smoothness and the safety of the operation of the train can be guaranteed.

The invention discloses a skid of an embedded medium-low speed maglev train maintenance platform. The skid comprises a hollow shell crossing two sides of a rail and power supply rails arranged on theshell in parallel, wherein the shell is connected through a plurality of cross beams, a plurality of rail wheels and a plurality of radial positioning structures thereof are arranged in each shell, the radial positioning structure comprises a shaft and a key, the shaft horizontally penetrates through the rail wheel and stretches across two sides of the shell, keys are arranged in a key groove of the shaft and a key groove of the rail wheel, axial positioning structures used for ensuring that the rail wheels and the shafts are relatively static in the axial direction are arranged on the two sides of the rail wheels, and the axial positioning structure comprises a spacer sleeve, a bearing and a check ring. The skid is advantaged in that a technical problem of high driving energy consumptionin the maintenance process of a maglev train in the prior art is solved, and the skid has advantages of compactness, reliability, convenience in maintenance, simple structure and the like.

The invention discloses a longitudinal and cross beam type high-speed magnetic levitation steel structure track panel which comprises two longitudinal beams symmetrically arranged in the line direction and a plurality of cross beams arranged between the longitudinal beams in the direction perpendicular to the line direction. The longitudinal beams comprise sliding top plates (7) of rail functionalparts, track panel longitudinal beam webs (9) and pi-shaped steel (10), and the lower ends of the track panel longitudinal beam webs (9) and the transverse center of the pi-shaped steel (10) are aligned and welded; the cross beams comprise track panel cross beam top plates (4), track panel cross beam bottom plates (5) and track panel cross beam webs (6); the two transverse ends of the track panelcross beam top plates (4) are welded to the inner sides of the sliding top plates (7) of the rail functional parts; the two transverse ends of the track panel cross beam bottom plates (5) are weldedto the inner side face of the pi-shaped steel (10); and the two transverse ends of the track panel cross beam webs (6) are welded to the inner sides of the track panel longitudinal beam webs (9). According to the longitudinal and cross beam type high-speed magnetic levitation steel structure track panel, the stable suspension gap and lateral distance between a magnetic levitation train body and the track panel can be guaranteed, and contactless guidance in the horizontal direction is achieved.
