Firm in connection fast brake block that dispels heat

The utility model relates to a firm in connection fast brake block that dispels heat, include the steel backing and the friction material layer that bond by the binder, the steel backing is equipped with by violently indulging the net that crisscross muscle formed with one side that friction material layer is connected, friction material layer is equipped with the recess that corresponds with themuscle with one side that the steel backing is connected, muscle card on the steel backing is gone into in friction material layer's the recess. The beneficial effects of the utility model are that: utilize during muscle card on the steel backing goes into friction material layer's recess, can increase the area of contact between steel backing and friction material layer on the one hand, increasethe radiating effect, on the other hand, the mode of muscle and groove phase block can make friction material layer and steel interdorsal be connected more firm. 本实用新型涉及种连接牢固散热快的刹车片，包括由黏合剂粘结的钢背和摩擦材料层，所述钢背与摩擦材料层连接的侧设有由横纵交错的筋形成的
