Fig. 1 is a schematic view of a conventional brake shoe. The middle part of current brake hoof is provided with tendon 2, and tendon 2 is the structure of T type, and the both ends and the engaging lug 3 of tendon 2 are connected, and when current brake hoof adopted casting process production, only can carry out the parting from the middle part of brake hoof, and the engaging lug lies in the both sides of die joint promptly, for the shaping of engaging lug and the taking out of brake hoof, need set up the core alone at the groove at engaging lug middle part, increased brake hoof casting cost, and the casting process is more complicated.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a drum brake's brake shoe solves current brake shoe casting process problem complicated, with high costs.
In order to realize the above-mentioned purpose, the utility model provides a drum brake's brake shoe, including curved hoof board, the both ends of hoof board are provided with connecting block one and connecting block two, be connected through connecting plate one between the curb plate middle part of connecting block one and connecting block two, connect through connecting plate two between another curb plate middle part of connecting block one and connecting block two, the side of connecting plate one and connecting plate two and the internal surface connection of hoof board, be provided with a plurality of strengthening rib between connecting plate one and the connecting plate two, be provided with the pinhole of installation reset spring round pin axle on connecting plate one and the connecting plate two, be provided with the connecting hole of being connected with the bottom plate on connecting block one and the connecting block.
Preferably, the brake shoe is of a unitary construction.
Preferably, the first connecting plate and the second connecting plate are of arc-shaped flat plate structures, and a plurality of first stiffened plates are arranged between the first connecting plate and the inner surfaces of the shoe plates and between the second connecting plate and the inner surfaces of the shoe plates.
Preferably, the first stiffened plates are of an L-shaped structure, and connecting ribs perpendicular to the first stiffened plates are arranged between the adjacent first stiffened plates.
Preferably, a second stiffened plate is arranged between the two sides of the second connecting block and the shoe plate.
A drum brake's brake shoe, set up two connecting plates on the internal surface of hoof board, connecting block one is in same plane with the curb plate and the connecting plate of connecting block two to the thickness of connecting plate one and connecting plate two is less than the thickness of curb plate, the shaping of the brake shoe of being convenient for with get the piece, need not set up solitary core and carry out the shaping, reduced casting cost, simplified casting process.
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

Detailed Description
Examples
Fig. 2 is a schematic structural view of an embodiment of a brake shoe of a drum brake according to the present invention. As shown in the drawing, a brake shoe of drum brake, includes curved shoe plate 1, and the both ends of shoe plate 1 are provided with connecting block one 6 and connecting block two 7, all are provided with the connecting hole on connecting block one 6 and the connecting block two 7. The connecting hole on the first connecting block 6 is used for rotatably connecting the roller, and the connecting hole on the second connecting block 7 is used for rotatably connecting the base plate 13 through a pin shaft. The first connecting plate 4 and the second connecting plate 5 are both provided with two side faces. The middle parts of the side plates of the first connecting block 6 and the second connecting block 7 are connected through a first connecting plate 4, and the middle parts of the other side plates are connected through a second connecting plate 5. The first connecting plate 4 and the second connecting plate 5 are arranged in parallel, and the thickness of the first connecting plate 4 and the thickness of the second connecting plate 5 are smaller than that of the side plate.
The first connecting plate 4 and the second connecting plate 5 are both arc-shaped flat plate structures, and the side surfaces of the first connecting plate 4 and the second connecting plate 5 are connected with the inner surface of the shoe plate 1 in a seamless mode. A plurality of reinforcing ribs 8 are arranged between the first connecting plate 4 and the second connecting plate 5, and the strength of the first connecting plate 4 and the strength of the second connecting plate 5 are improved. A plurality of first stiffened plates 9 are arranged between the inner surfaces of the first connecting plate 4, the second connecting plate 5 and the shoe plate 1, the first stiffened plates 9 are of L-shaped structures, two right-angle surfaces of the first stiffened plates 9 are respectively in seamless connection with the shoe plate 1 and the first connecting plate 4 or the second connecting plate 5, and inclined surfaces of the first stiffened plates 9 are arc-shaped surfaces.
