[0071] Embodiment two

[0072] The friction plate provided by the embodiment of the utility model has all the beneficial effects of the friction plate backboard in the embodiment one, and thus has all the beneficial effects of the embodiment one, which will not be repeated here.

If the heat is directly transmitted to the friction plate backboard, the brake chamber will be overheated, and the brake fluid may be blocked by air in severe cases. Therefore, a heat insulation layer is arranged between the friction material and the friction plate backboard. The heat insulation layer needs to have high-temperature resistance and high-pressure resistance, effectively insulate the high temperature of braking, and thus maintain a stable braking distance.
