Kingrail applied A high-strength light-weight rail vehicle tire and a production process thereof are used, and relate to the technical field of alloy preparation.

An elastic wheel for a rail vehicle, an elastic wheel assembly and a rail vehicle belong to the technical field of rail vehicles. The elastic wheel for a rail vehicle of the present invention includes a rim, a wheel center, and a damping element located between the rim and the wheel center, wherein the wheel center is provided with an on-axis for accommodating and installing a wheel-mounted brake disc. An annular groove that is concave in the direction opposite to the side of the tire. The invention can realize the reasonable installation of the wheel-mounted brake disc on the elastic wheel, and the elastic wheel can withstand the thermal load generated by the wheel-mounted brake disc, has excellent vibration and noise reduction performance, long service life and good bearing performance .

A method for pressing an elastic wheelset of a rail vehicle, comprising the following steps: S1, selecting an installation tool that matches the axle, and the inner diameter of the installation tool is larger than the inner diameter of the wheel center of the elastic wheel and can be pressed onto the side of the wheel center; S2, Set the guide sleeve on the right end of the axle to keep the center line of the axle and the center line of the press piston collinear; S3, apply lubricating oil on the axle wheel seat, and pass the elastic wheel through the The guide sleeve is pre-installed on the axle, while keeping the elastic wheel perpendicular to the axle; S4, the installation tool is blocked on the side of the wheel center of the elastic wheel, and the thimble of the press presses against the axle The axle center of the axle is slowly pressurized, so that the axle slowly enters the center hole of the wheel center of the elastic wheel until the installation of the elastic wheel is completed. The invention can improve the success rate of pressing and can ensure the quality of pressing.

An online replacement tool for elastic wheels belongs to the technical field of online replacement of elastic wheels. , The anti-drop bolt installed on the outer side of the elastic wheel of the fixed bracket and the lifting ring bolt on the top of the fixed bracket; the pressure ring disassembly tool is composed of a pressure ring disassembly connecting block and two disassembly bolts passing through the pressure ring disassembly connecting block. One The second dismantling bolt is fixed on the process hole of the elastic wheel pressing ring, and the other dismantling bolt two is on the wheel screw; The brackets of the rack and the mobile rack and the top-tight handle through the mobile rack. The tooling is simple in operation, simple in structure, time-saving and labor-saving, and low in cost, and can be used for online replacement of most elastic wheels

The tire is used to assemble rubber elastic wheels. The tire is a rolled seamless steel ring, which is pressed on the wheel center by thermal effect. The wheel center is a cast steel wheel body, and there is a layer of rubber body between the tire and the wheel center. If bubbles or slag remain during the rolling of the tire, it may crack under the dynamic action of high pressure load, or it may be caused by "fatigue fracture" due to the aging of the tire material. KINGRAIL's tires ensure quality and safety.
