M730A rail tyres for for locomotive and wagon metro 730mm outside diameter resilient wheels

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.

Method for measuring wear degree of mechanical elastic wheel, steps: establish a finite element model of mechanical elastic wheel; use the mechanical elastic wheel modal test analysis system to verify the correctness of the mechanical elastic wheel finite element model; use the verified mechanical elastic wheel finite element model to calculate The natural frequencies of each order of the mechanical elastic wheel under different wear degrees; the calculated natural frequency value of each order is used as the input of the BP neural network, and the wear amount of the mechanical elastic wheel is used as the output of the BP neural network to train the BP neural network model; The measured natural frequencies of each order of the mechanical elastic wheel are input into the trained BP neural network, and the wear amount of the mechanical elastic wheel is obtained by solving. The invention can accurately measure the thickness of the mechanical elastic wheel pattern under different wear degrees, ensure that the thickness of the tire pattern is within a safe range, and reduce the safety problem caused by excessive tire wear.

The tires of KINGRAIL are easy to transport, because they are a kind of pressure plate packaging of wheel tires, which includes a tire outer cylinder and at least three sets of fasteners. Outside the wheel rim, the outer cylinder of the rim includes several rim placement layers; each group of fasteners has the same structure and specification, and the fasteners include two spacers, two long double-ended screws and four nuts, The two spacers are respectively arranged on the upper end and the lower end of the outer cylinder of the tire. There are two through holes on the spacer block. The screw rod is set close to the inner circle of the outer cylinder of the tire, and the other double-headed screw is set close to the outer circle of the outer cylinder of the tire. The pressing plate type packaging of the wheel rim proposed by the utility model has the advantages of simple structure, convenient processing and manufacturing, and convenience for the transportation and storage of the wheel rim.

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.

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.
