Problems solved by technology

[0002] With the continuous increase of urban population and the continuous expansion of urban scale, the original public transportation mode can no longer meet the needs of urban development, urban transportation is developing towards diversification, and new environmentally friendly tram systems are being promoted and used in major cities; The system adopts an embedded track design, which can realize the advantages of mixed traffic with ground vehicles and pedestrians; the key factor for the generation of noise during vehicle operation and the fatigue damage of steel wheels and rails is the interaction force between the wheels and rails; If the line is not smooth and disturbed, the force between the wheel and the rail increases with the increase of the unsprung mass during the operation of the vehicle. Therefore, the unsprung mass should be reduced as much as possible while ensuring the stable operation of the vehicle; An elastic element is embedded between the hoop and the wheel core, and the hoop and the wheel are elastically assembled together, which greatly reduces the unsprung mass; thereby reducing the force between the wheel and the rail during the running of the vehicle, and the non-elastic components on the wheel set. The vibration is also reduced, the wear is reduced, and the noise caused by the unevenness of the line is reduced; due to these advantages, elastic wheels have been widely used in foreign light rail low-floor trams, subway vehicles, and intercity trains; now Some elastic wheels are easy to wear and have poor noise reduction effect. In addition, there is no complete set of production testing standards

Embodiment 1

[0023] like figure 1 and figure 2 As shown, the elastic wheel of the present invention comprises a wheel bottom plate 1 and a wheel end plate 2; and a rubber 3 installed between the wheel bottom plate and the wheel end plate; the wheel bottom plate 1 and the wheel end plate 2 are all made of Q235 material Made; the rubber 3 is composed of natural rubber as the main material;

[0024] In yet another embodiment, the exposed metal of the wheel bottom plate 1 and the wheel end plate 2 is sprayed with a gray antirust paint layer.

[0025] In yet another embodiment, the wheel bottom plate 1 and the wheel end plate 2 are axially provided with arc-shaped concave-convex surfaces.

[0026] Wherein, the requirements of the rubber 3 are as follows: hardness 63±3°Sha, tensile strength ≥ 15Mpa, elongation at break ≥ 300%.

[0027] Wherein, its axial stiffness of described wheel is as follows:

[0028] Axially load 2.5mm at a loading speed of 1mm / min and then unload, preload twice in th...

Embodiment 2

[0034] Randomly select two finished wheels and load them into image 3 On the jig shown, the test is divided into two times, each time a wheel is loaded on the test jig, and the stiffness is 10.5±20% kN / mm when the axial load is 2.5mm; the test results are as follows Figure 5 and Image 6 As shown, the axial stiffness of sample 1 is 11.16 kN / mm, and the axial stiffness of sample 2 is 10.10 kN / mm.

Embodiment 3

[0036] Randomly select two finished wheels and load them into Figure 4 On the jig shown, two samples are tested at the same time. When the distance between the two stress surfaces of the product is compressed to 32mm, the lateral load is 6.875kN, and the shear stiffness value is 1.125±30%kN / mm; the test results are as follows Figure 7 As shown, the shear stiffness is 1.255kN / mm.

[0037] In the elastic wheel of the present invention, the wheel bottom plate and the wheel end plate are made of Q235 material, its chemical composition can meet the requirements, and the rubber is mainly made of natural rubber. Standard test and calculation of shear stiffness to ensure that it can meet the application requirements.
