Abstract
The utility model discloses a drum brake for automobiles, which comprises a drum body, a mounting part is arranged at one end of the drum body, a mounting hole used for being connected with an automobile hub is arranged on the mounting part, a circular bulge is arranged on the side wall of the outer periphery of the other end of the drum body, and a friction strengthening device is arranged on the surface of the inner periphery of the drum body. The friction strengthening device increases the friction force between the drum brake and brake shoes when in braking, so as to have better the braking effect.
Description
Technical field
The utility model relates to automobile technical field, relates in particular to a kind of brake drum.
Background technique
At present, brake drum is generally used in braking automobile braking, but after brake drum used of a specified duration, the frictional force between brake drum and the brake shoes reduced, and so just needs replacing brake drum in time, has reduced the working life of brake drum.
The model utility content
Technical problem to be solved in the utility model provides the brake drum for automobile that a kind of frictional force is bigger, braking effect is better, longer service life is of a specified duration.
For solving the problems of the technologies described above, the technical solution of the utility model is: brake drum for automobile, comprise bulging body, described bulging body one end is provided with assembly department, described assembly department is provided with and is used for the mounting hole that is connected with automotive hub, described bulging body the other end outer peripheral sidewall is provided with annular projection, and perimeter surface is provided with the friction enhanced device in the described bulging body.
As optimized technical scheme, described friction enhanced device is netted striped.
As the improvement to above-mentioned technology, described bulging body is gray iron cast iron drum body.
Owing to adopted technique scheme, brake drum for automobile, comprise bulging body, described bulging body one end is provided with assembly department, described assembly department is provided with and is used for the mounting hole that is connected with automotive hub, described bulging body the other end outer peripheral sidewall is provided with annular projection, and perimeter surface is provided with the friction enhanced device in the described bulging body; Frictional force when the friction enhanced device that perimeter surface is provided with in the described bulging body has been strengthened brake between brake drum and the brake shoes makes braking effect better.
Description of drawings
Accompanying drawing is the utility model embodiment's a sectional drawing;
Among the figure: 1-drum body; The 2-mounting hole; The netted striped of 3-; The 4-annular projection.
Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment:
As shown in drawings, brake drum for automobile comprises bulging body 1, described bulging body 1 one ends are provided with assembly department, described assembly department is provided with and is used for the mounting hole 2 that is connected with automotive hub, and described bulging body 1 the other end outer peripheral sidewall is provided with annular projection 4, and perimeter surface is provided with the friction enhanced device in the described bulging body 1.
Described friction enhanced device is netted striped 3, and the frictional force during strong like this brake between brake drum and the brake shoes makes braking effect better.
Described bulging body 1 is gray iron cast iron drum body.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
All are from design of the present utility model, and the structure conversion of having done without creative work all drops within the protection domain of the present utility model.
