Abstract
The utility model discloses a brake drum which comprises a drum shell (1), wherein the drum shell (1) is in the shape of a bell jar, a flange plate (2) is arranged at one end of the drum shell (1), a convex ring (3) is arranged on the outer side of the other end, and a threaded hole (4), a through hole (5) and a blind hole (6) are distributed on the circumference of the flange plate (2). The brake drum has the benefits that the blind hole is drilled during the casting process of the brake drum, thereby ensuring the dynamic balance performance of the brake drum, leading the service life to be longer, being good in heat radiation, leading the processing technology to be simple and saving cost.
Description
Technical field
The utility model relates to the automotive brake field, especially a kind of brake drum in the break.
Background technique
So-called brake drum is exactly the part of drum brake brake system, and during brake, piston is exerted pressure to two pairs of half-moon-shaped brake shoes, makes it be adjacent to the tympanum inwall, thereby produces the rotation that friction stops wheel.At present, the brake drum in the drum brake is the HT200 cast structure, and castability is difficult to control, often have casting defects such as sand holes, pore, shrinkage porosite, slag inclusion, crackle, the casting brake drum is because of casting defect, and dynamic balance performance certainly exists problem, occurs unusual vibrations when easily causing vehicle driving.
The model utility content
The purpose of this utility model promptly is to overcome the shortcoming of prior art, proposes a kind of simple in structure, manufacturing process is simple, processing cost is low brake drum.
The purpose of this utility model is achieved through the following technical solutions: a kind of brake drum, and it comprises bulging shell, and the drum shell is the bell jar shape, and an end of drum shell is provided with flange plate, and the other end outside is provided with protruding circle, is distributed with tapped hole, through hole and blind hole on the flange plate circumference.
Described tapped hole is a tapped hole facing each other.
Described blind hole is a blind hole facing each other.
The beneficial effects of the utility model show: brake drum is drilled with blind hole in casting processing, has guaranteed the brake drum dynamic balance performance, longer service life, and thermal diffusivity is good, and processing technology is simple, saves cost.
Description of drawings
Fig. 1, front elevation of the present utility model
Fig. 2, the A-A sectional view of the utility model Fig. 1
Among the figure, 1-drum shell, 2-flange plate, the protruding circle of 3-, 4-tapped hole, 5-through hole, 6-blind hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described, but that protection domain is not limited to is described.
As Fig. 1 and Fig. 2, a kind of brake drum, it comprises bulging shell 1, and drum shell 1 is the bell jar shape, and an end of drum shell 1 is provided with flange plate 2, and the other end outside is provided with protruding circle 3, is distributed with tapped hole 4, through hole 5 and blind hole 6 on flange plate 2 circumference.Described tapped hole 4 is a tapped hole facing each other, and described blind hole 6 is a blind hole facing each other.
During use, on brake drum, generally have only a wheel cylinder, after wheel cylinder was subjected to from master cylinder fluid power when braking, wheel cylinder two ends piston can push up the hoof end of brake shoe to the left and right simultaneously, makes its inwall that is adjacent to brake drum, thereby produced the purpose that friction reaches brake.
Claims (3)
1. brake drum, it is characterized in that: it comprises bulging shell (1), and drum shell (1) is the bell jar shape, and an end of drum shell (1) is provided with flange plate (2), the other end outside is provided with protruding circle (3), is distributed with tapped hole (4), through hole (5) and blind hole (6) on flange plate (2) circumference.
2. a kind of brake drum according to claim 1 is characterized in that: described tapped hole (4) is a tapped hole facing each other.
