Definitions

• the present invention relates to a friction pad for a disc brake, and more particularly to a friction pad that reduces heat transmitted from the friction pad to a carrier or the like during a brake operation.
• Fig. 1 shows an example of a general vehicle disk brake. That is, the carriage 1 is provided on a non-rotating part or a fixed member (not shown) attached to the non-rotating part of the vehicle so as to be movable in the directions of the arrows A and B.
• the brake oil 5 is introduced from the stationary cylinder, and the piston 4 moves in the direction of the arrow A according to the pressure of the brake oil 3.

• this type of disc brake has two major drawbacks.
• the first is that the pack plate is made of iron, so the pack plate itself becomes heavy, and the members supporting the smaller pack plate must also be rugged, which has the disadvantage of increasing the weight of the entire apparatus.

• the weight problem has not been solved, and if there is no suitable method to join the packing plates 5 and 10 to the heat insulating material, and the device has been used for a long time, the heat insulating material will not be used.
• the disadvantage is that it is separated from On the other hand, in the latter case, for example, when the pack plates 5, 10 are made of a lightweight resin plate having low thermal conductivity, the strength against bending and compressive forces is insufficient, and the pack plates 5, 10 are eventually broken, Even if it is changed to ceramic just to increase the strength of the pack shake 5 "and 10 ", the thermal conductivity of the ceramic is not much different from that of iron, so it has a sufficient heat insulating effect there 3 ⁇ 4 drawback force that it is possible to get a.
