AI Technical Summary
The shock absorbing pads of existing articulated bogies cannot connect parts, and when they withstand tensile and squeeze forces in various directions, the lack of constraints leads to excessive or too small deformation, resulting in product failure and shortened service life.
A rubber shock absorbing pad for articulated bogies is designed. By adding upper and lower metal plates and setting connection holes and avoidance holes on them, the fixed connection and shock absorbing effect between the articulated plate and the windshield device is realized. The rubber is vulcanized between metal plates, with metal exposed bread glue on the sides, and the rubber arc is designed for added stability and service life.
By constraining the elastic deformation of the rubber pad, preventing excessive or excessively small deformation, the service life of the product is extended, and the shock absorption effect and product stability are improved.

[0031] Preferably, the rubber 2 and the inner side of the upper metal plate 1 , and the rubber 2 and the outer side of the lower metal plate 3 are integrally vulcanized and formed.
[0032] like Figure 2 As shown, the surface of the upper metal plate 1 is designed with a threaded connection port 6 and an avoidance hole 7 for the mounting hole 8 of the lower metal plate 3 , and the surface of the lower metal plate 2 is designed with a mounting hole 8 and an avoidance hole 10 for the above-mentioned threaded connection port 6 of the upper metal plate 1 .
