Abstract
The utility model provides an automobile brake drum. The automobile brake drum comprises a brake drum body, wherein the brake drum body is cylindrical, a through-hole is arranged in the center of the brake drum body along the axis, at least two heat-dissipating ribs are evenly distributed on the circumference of the outer wall of the brake drum body, a flange plate is installed at one end of the brake drum body, and at least two positioning grooves are evenly distributed on the circumference of the surface of the flange plate. According to the automobile brake drum, positioning grooves are arranged, so that the positioning is facilitated, and the installation efficiency is improved; heat-dissipating ribs are arranged on the outer wall of the brake drum body, so that the heat-dissipating performance can be improved; and heat-dissipating ribs are in an arc strip-shaped structure, so that air streams can be produced during operation, heat produced by braking can be carried off, and the heat-dissipating performance can be improved.
Description
Technical field
The utility model relates to a kind of braking automobile parts, particularly a kind of automobile brake drum.
Background technique
Brake drum is exactly the some of drum brakes 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, therefore can produce a large amount of heat energy in brake process.Traditional brake drum does not have positioning device, and is therefore very inconvenient when mounted, affect installation efficiency, and present brake drum heat dispersion is poor.
The model utility content
The technical problem that (one) will solve
The technical problems to be solved in the utility model provides a kind of perfect heat-dissipating, automobile brake drum easy for installation.
(2) technological scheme
For solving the problems of the technologies described above, the utility model provides a kind of automobile brake drum, comprise brake drum body 5, described brake drum body 5 is cylindrical, described brake drum body 5 central authorities offer through hole along axis, described brake drum body 5 outer walls circumferentially are evenly equipped with at least two radiating fin 6, and described brake drum body 5 one end ends are equipped with flange plate 4, circumferentially are evenly equipped with at least two locating slots 3 on described flange plate 4 cards.
Further, described radiating fin 6 is for being the list structure of circular arc type.
Further, described radiating fin 6 and described brake drum body 5 are one-body molded.
(3) beneficial effect
The utility model automobile brake drum is provided with locating slot, and installation efficiency has been improved in convenient location; Be provided with radiating fin at brake drum body outer wall, improve heat dispersion; Radiating fin is the list structure of circular arc type, in running, can produce air-flow, takes away because the heat energy that brake produces has further improved heat dispersion.
Description of drawings
Fig. 1 is the structural representation of the utility model automobile brake drum.
Embodiment
Consult Fig. 1, the utility model provides a kind of automobile brake drum, comprise cylindrical brake drum body 5, these brake drum body 5 central authorities offer through hole along axis, brake drum body 5 outer walls circumferentially are evenly equipped with at least two radiating fin 6, this radiating fin 6 is for being the list structure of circular arc type, in rotation process, can produce air-flow, take away because the heat energy that brake produces has improved heat dispersion, brake drum body 5 one end ends are equipped with for the flange plate 4 that connects, this flange plate 4 is provided with some mounting holes 2, is used for bolt and connects, and circumferentially is evenly equipped with at least two locating slots 3 on flange plate 4 cards, play the role of positioning when mounted, the convenient installation, preferred, locating slot 3 has three; Radiating fin 6 and brake drum body 5 are one-body molded in the utility model.The utility model automobile brake drum is provided with locating slot, and installation efficiency has been improved in convenient location; Be provided with radiating fin at brake drum body outer wall, improve heat dispersion; Radiating fin is the list structure of circular arc type, in running, can produce air-flow, takes away because the heat energy that brake produces has further improved heat dispersion.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
