【０００４】しかし、摩擦材を冷却水によって冷却する
といっても、冷却水への放熱は急激ではない為、ある程
度の熱は摩擦材に溜まることとなる。However, even if the friction material is cooled with cooling water, the heat radiation to the cooling water is not rapid, so that some heat is accumulated in the friction material.

Due to the increased thickness, heat transfer from the friction surface, which is pressed by the disc rotor of the friction material and generates a frictional force, to the pressing member is delayed. For this reason, the heat dissipation is deteriorated, and the temperature drop of the friction surface of the friction material is reduced.

The high thermal conductive material 3 and the pressing member 2 are conducted. The heat reaching the pressing member 2 is not rapidly dissipated by the cooling water, and the heat is accumulated in the friction material. However, the heat capacity between the friction surface 17 and the pressing member 2 is the same as the heat capacity of the high thermal conductive material 3. It is higher than the disc brake device without the conductive material 3. Therefore, the temperature rise of the friction material is low.

The heat capacity goes up. In addition, since the high thermal conductive material having higher thermal conductivity than the friction material and the pressing member is used, delay of heat conduction from the friction surface of the friction material to the pressing member is suppressed. It is possible to increase the heat capacity between the friction surface of the friction material and the pressing member while suppressing clogging and reduction in heat dissipation. Therefore, since the temperature drop of the friction surface of the friction material is large, partial melting or softening of the friction surface of the friction material is reduced, and the wear resistance of the friction material in the water-cooled disc brake device is improved.
