[0037] Example
[0038] Such as Figure 1 to Figure 10 As shown, the wheel-mounted brake disc of a high-speed train includes an inner disc body 11 and an outer disc body 12. The inner disc body 11 and the outer disc body 12 are both circular rings with a heat dissipation rib structure; the inner disc body 11 and the outer disc body The body 12 is located on the inner side and the outer side of the wheel web 81, and the planes on both sides are the friction surface 13 and the heat dissipation rib surface 14 respectively; figure 2 with Picture 10 , 6 sliding grooves 15 are distributed on the center circle 19 of the disc body on the side of the heat dissipation rib, and 6 sleeve holes 16 are evenly distributed on the distribution circle smaller than the middle circle of the disc body. There are 6 sleeve holes 17 evenly distributed on the distribution circle of the disk outer circumference; reference image 3 On the wheel web 81 that is in contact with the disc body, corresponding t...
