Abstract
The invention discloses a car brake drum. The car brake drum comprises a cylindrical brake drum main body, wherein one end of the brake drum main body is a connecting part while the other end thereof is a brake part; more than three air door grooves are formed in the outer edge of the connecting part; a pressing steel ring is arranged on the outer edge of the brake part; multiple circular arc-shaped radiating ribs are uniformly arranged on the outer wall of the brake drum main body. The car brake drum is convenient to install as more than three air door grooves are formed in the outer edge of the connecting part of the brake drum and the number of the air door grooves is added, is good in heat radiation effect as the circular arc-shaped radiating ribs are uniformly arranged on the outer wall to generate an airflow during the work time, and is not easy to crack as the pressing steel ring is arranged on the outer edge of the brake part of the brake drum.
Description
Technical field
The present invention relates to a kind of brake drum, be specifically related to a kind of automobile brake drum.
Background technique
A part for brake system during brake drum, during brake, brake block is pressed close to tympanum inwall and is produced frictional force, makes vehicle stop, and this often produces very large heat, and existing brake drum not only radiating effect is bad; Because the valve position groove of brake drum only has two, install also cumbersome; General brake drum generally adopts gray cast iron manufacture, easily breaks.
Existing brake drum radiating effect is poor in sum, and inconvenience is installed, and easily breaks.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of automobile brake drum, solved existing brake drum radiating effect poor, inconvenience is installed, crackly problem.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of automobile brake drum, comprise brake drum body, described brake drum body is cylindrical, one end of described brake drum body is attachment portion, the other end is brake portion, and the outer rim of described attachment portion is provided with three above valve position grooves, and the outer rim of described brake portion is provided with compressing steel ring, on the outer wall of described brake drum body, be evenly provided with some radiating fin, described radiating fin is circular arc.
Described valve position groove evenly arranges.
Described radiating fin, valve position groove and the moulding of brake drum body integrally casting.
Beneficial effect of the present invention: 1, the present invention arranges more than three valve position grooves by the outer rim of the attachment portion at brake drum, has increased valve position groove number, easy for installation; 2, on outer wall of the present invention, be evenly provided with circular arc radiating fin, when work, can produce air-flow, good heat dissipation effect; 3, the present invention arranges compressing steel ring by the outer rim of the brake portion at brake drum, makes brake drum be difficult for cuing open and splits.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
A kind of automobile brake drum, comprise brake drum body, described brake drum body is cylindrical, one end of described brake drum body is attachment portion 4, the other end is brake portion 5, the outer rim of described attachment portion 4 is provided with three above valve position grooves 2, described valve position groove 2 evenly arranges, the outer rim of described brake portion 5 is provided with compressing steel ring 1, on the outer wall of described brake drum body, be evenly provided with some radiating fin 3, described radiating fin 3 is circular arc, described radiating fin 3, valve position groove 2 and the moulding of brake drum body integrally casting.
Above-described a kind of automobile brake drum arranges more than three valve position grooves by the outer rim of the attachment portion at brake drum, has increased valve position groove number, easy for installation; By circular arc radiating fin is evenly set on outer wall, when work, can produce air-flow, good heat dissipation effect; Outer rim by the brake portion at brake drum arranges compressing steel ring, makes brake drum be difficult for cuing open and splits.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
