DETAILED DESCRIPTION
[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0018] like Figure 1 , 2 As shown in Figures 3 and 4, the drum brake comprises a brake body 2, on which a brake caliper 1 is symmetrically arranged, on which a brake pad 4 is arranged, and on which a plurality of mounting holes 5 are arranged. The mounting holes 5 are connected with a sound-generating component 6, on which a mounting shell 16 is arranged. A mounting cavity 8 is arranged in the mounting shell 16, on which a roller 10 is arranged, on which a plurality of elastic sheets 12 are evenly distributed, and in which a support member 7 is further arranged. A support spring 17 is arranged between the support member 7 and the mounting cavity 8, and the roller 10 is arranged in the brake pad 4. After the brake pad 4 is worn, the roller 10 will be exposed, and the rotating parts contacted by the roller 10 rotate passively, and the support member 7 is repeatedly moved by the elastic sheet 12. The support member 7 is repeatedly installed on the roller 10 to make a collision sound, and the wear condition of the brake pad 4 can be judged by the sound emitted.
[0019] Preferably, a guide block 15 is provided on the support member 7 , a striker 13 is provided on the guide block 15 , and a guide fillet 9 is provided on the top of the striker 13 .
[0020] Preferably, the brake caliper 1 is provided with a plurality of clamping blocks 14 , each of which is provided with a clamping groove 18 , and the mounting housing 16 is provided with a plurality of clamping portions 19 .
[0021] Preferably, a support spring 17 is provided between the brake caliper 1 and the mounting housing 16. When installing the sounding component 6, the sounding component 6 is pressed and the spring is compressed. The sounding component 6 is rotated to make the snap-fitting portion 19 embed into the snap-fitting groove 18 to complete the installation locking.
[0022] Preferably, a detachable rotating shaft 11 is provided on the mounting shell 16, and the roller 10 is snap-connected to the rotating shaft 11. The detachable rotating shaft 11 facilitates the disassembly and assembly of the sound-emitting component 6.
