The alarm plate assemblies in the front-arranged hoof belt alarm plate assembly and the rear-arranged hoof belt alarm plate assembly are identical in structure and installation.
The preposed hoof belt alarm plate assembly comprises a preposed hoof tendon, a preposed hoof plate and a preposed friction plate,
one end part of the bowl-shaped alarm sheet facing the front friction sheet is used as a head part, the head part of the bowl-shaped alarm sheet is embedded in a groove formed in the front friction sheet, and the tail part of the bowl-shaped alarm sheet is fixed on the front hoof sheet through a fixing rivet.
The bowl-shaped alarm plate is arranged in a groove of the front friction plate, and the fixing rivet penetrates through a front shoe plate of the front brake shoe and a mounting hole in the front friction plate and is fixed through riveting.
The bowl-shaped alarm sheet is made of metal materials.
The utility model has the advantages that:
the utility model discloses a timely feedback when the brake shoe friction disc wearing and tearing limit in the drum brake, the unable accurate, timely defect of changing of brake shoe in the use has been solved in the drum brake.
The utility model discloses use, change cycle for present drum brake shoe provide accurate signal feedback, avoided using the whole car of drum brake to sell the waste of a large amount of manpower and materials in the back.

In the figure: the brake comprises a front friction plate 1, a front shoe plate 2, a front shoe rib 3, an alarm plate 4, a bowl-shaped alarm plate 5, a fixing rivet 6, a front shoe belt alarm plate assembly 6, a brake bottom plate 7, a brake wheel cylinder assembly 8 and a rear shoe belt alarm plate assembly 9.
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2 and fig. 6-8, the drum brake of the present invention includes a brake base plate 7, and a brake wheel cylinder assembly 8, a front shoe belt alarm sheet assembly 6 and a rear shoe belt alarm sheet assembly 9 installed on the brake base plate 7, and is characterized in that: a plurality of alarm sheet assemblies are uniformly arranged on the peripheral surfaces of the front-arranged hoof belt alarm sheet assembly 6 and the rear-arranged hoof belt alarm sheet assembly 9.
The alarm sheet assemblies in the front-arranged hoof belt alarm sheet assembly 6 and the rear-arranged hoof belt alarm sheet assembly 9 are identical in structure and installation.
As shown in fig. 1, the implementation is described by taking a front hoof belt alarm plate assembly 6 as an example, the front hoof belt alarm plate assembly 6 includes a front tendon 3, a front hoof plate 2 and a front friction plate 1, each alarm plate assembly includes a bowl-shaped alarm plate 4 and a fixing rivet 5, the bowl-shaped alarm plate 4 is a bowl-shaped structure with a central through hole, as shown in fig. 4, a plurality of friction protrusions are arranged on a circumferential edge of an outward end surface of the bowl-shaped structure, each friction protrusion is uniformly distributed along a circumference at intervals to form a saw-toothed gear ring structure, as shown in fig. 3, the fixing rivet 5 is connected to the hoof plate through the through hole of the bowl-shaped structure, so that the bowl-shaped alarm plate 4 is fixed to the.
As shown in fig. 3, the bowl-shaped alarm plate 4 faces the end of the front friction plate 1 as the head, the head faces the working surface of the friction plate, the head of the bowl-shaped alarm plate 4 is embedded in a groove formed on the front friction plate 1, and the tail of the bowl-shaped alarm plate 4 is fixed on the front shoe plate 2 through a fixing rivet 5. In the abrasion process of a front friction plate 1 of the drum brake, the head X of the alarm plate 4 is contacted with a brake drum to generate mutual friction, so that the alarm plate and the brake drum generate noise through friction, and acoustic alarm is performed.
As shown in fig. 5, mounting holes are uniformly distributed on the front shoe plate 2 and the front friction plate 1, the bowl-shaped alarm plate 4 is arranged in a groove of the front friction plate 1, and the fixing rivet 5 penetrates through the mounting holes on the front shoe plate 2 and the front friction plate 1 of the front brake shoe and is fixed through riveting.
The utility model discloses a working process is:
when the piston of the brake wheel cylinder acts on the front-arranged tendon and the rear-arranged tendon in the using process, the front-arranged brake shoe assembly moves towards the front side, and the rear-arranged shoe assembly moves towards the rear side, and is respectively contacted with and abraded by the brake drum.
Under normal conditions, the gear ring structure X at the head of the bowl-shaped alarm piece 4 is contacted with the brake drum to generate mutual friction, so that the alarm piece and the brake drum generate harsh noise to give an alarm.
Therefore, when the friction plate of the hoof reaches the abrasion limit, the hoof alarm can be timely realized, a user can be accurately and effectively reminded of timely replacing the hoof assembly, damage to peripheral parts caused by excessive abrasion of the hoof is reduced, and replacement cost is reduced. Because the alarm sheet is directly riveted by the rivet, the cost of the alarm sheet is increased, and the alarm sheet is saved relatively.
The above examples are illustrative of the present invention and are not intended to be limiting, and any simple modification of the present invention is within the scope of the present invention.
