Beschreibung
Zusammenfassung:	The utility model discloses a drum brake which comprises a brake drum, a first brake shoe, a second brake shoe, a brake cylinder and a friction plate. Both the first brake shoe and the second brake shoe are hollow. The first brake shoe and the second brake shoe each contain cooling liquid. The friction plate is arranged on the inner circumferential face of the brake drum and is in friction fit with the circumferential direction of the first brake shoe and the second brake shoe. The drum brake further comprises a first cooling pipeline, a second cooling pipeline, a water outlet pipeline, a water inlet pipeline and a radiator. The two ends of the first cooling pipeline are communicated with the first end of the first brake shoe and the first end of the second brake shoe respectively. The two ends of the second cooling pipeline are communicated with the second end of the first brake shoe and the second end of the second brake shoe respectively. One end of the water outlet pipeline and one end of the water inlet pipeline are communicated with the first brake shoe and the second brake shoe respectively. The second end of the water outlet pipeline and the second end of the water inlet pipeline are communicated with a water inlet and a water outlet of the radiator respectively.
