The invention discloses a drum brake with a cooling device in the technical field of automobile part equipment, an air inlet hole is formed in the rear side wall of a drum brake body and connected with a cooling fan through an air guide pipe, a first water delivery pump is connected with a quantitative cylinder, a first electromagnetic water valve is arranged at a water outlet of the quantitative cylinder. The output end of the liquid level sensor is electrically connected with the single-chip microcomputer, a water inlet of the quantitative cylinder is connected with a second water delivery pump through a water delivery pipe, the second water delivery pump is connected with the water tank, a temperature detection element is arranged on the outer wall of a friction plate of the drum brake body, and the output end of the temperature detection element is electrically connected with the single-chip microcomputer. The drum brake is simple in structure and reasonable in design, on the premise that cooling of the brake is guaranteed, the spraying water amount is controlled, the problem that the heat dissipation effect is poor due to the fact that the added water amount is too large or too small is solved, water resources are saved, and the using effect is good.

    本发明公开了汽车部件设备技术领域的一种带有冷却装置的鼓式刹车,所述鼓式刹主体后侧壁开设有进风孔,所述进风孔通过导风管与散热风扇连接,所述第一输水泵与定量筒连接,所述定量筒的出水口处设置有第一电磁水阀,所述液位传感器的输出端与单片机电性连接,所述定量筒的进水口通过输水管连接第二输水泵,所述第二输水泵与水箱连接,所述鼓式刹主体的摩擦片外壁设置有温度检测元件,所述温度检测元件的输出端与单片机电性连接,本发明结构简单,设计合理,保证刹车器降温的前提下,控制喷洒的水量,避免加入水量过多或过少导致散热效果不佳的问题,也节约了水资源,使用效果好。
