Resilient Rail Car Wheel 550mm Tread Diameter UIC AAR Standard

Resilient Rail Car Wheel 550mm Tread Diameter UIC AAR Standard

The high-strength light-weight rail vehicle tire includes an outer tire, and the middle part of the inner surface of the side wall of the outer tire is integrally connected and fixed with a clamping seat, and the clamping seat includes a clamping table coaxial with the outer The retaining ring on the outside of the bottom surface of the clamping table, the end surface of the clamping table is evenly distributed with a number of threaded through holes; the bottom end surface of the outer tire is integrally connected and fixed with a tread ring, and the surface of the tread ring is an annular surface that completely overlaps with the bottom surface of the outer tire. The inner side is bent vertically outward to form an arc-shaped tread extending downward and outward, and the outer side of the annular surface is vertically bent outward to form an outer arc surface whose bottom end coincides with the outer edge of the arc-shaped tread. The tread of the tire of the present invention is made into a 5-degree inclined surface, so that the quality of the wheelset can be reduced, it is convenient to pass through the curve, and the tread wear can be relatively uniform. By lowering the center of gravity of the vehicle and reducing the mass of the wheelset, the flexibility of the track wheel to enter the track is improved.
The tire production and processing device for rail cars includes a grinding tool for the inner surface of the side wall of the tire, the grinding tool includes a support base, and the support base includes a support plate and a first positioning shaft installed and fixed at the center of the surface of the support plate. A positioning power plate is installed and fixed on the positioning shaft, a limit stop ring is vertically fixed in the middle of the surface of the support plate, the first positioning shaft is located in the middle of the limit stop ring, and the side wall of the limit stop ring has several limit strip holes at equal angles. A tire locating seat is slidably clamped in the limit bar hole. The function between the tire locating seat and the locating power plate of the grinding tool of the utility model realizes the clamping and fixing of the tire, and then the grinding block and the inner surface of the side wall of the tire are pressed and contacted by the action of the pressing cylinder. Then it is rotated and polished without manual labor, which makes the polishing efficiency higher and the polishing more uniform. At the same time, the tire will not fall off and move during the polishing process.
