Abstract
The utility model belongs to the technical field of car braking and provides a brake drum. A plurality of rhomboid protrusions are arranged on the outer circumference surface of a brake drum body. A longitudinal rib corresponding to two adjacent rhomboid protrusions is arranged between each two adjacent rhomboid protrusions. Each longitudinal rib is uniform to the brake drum body along the extending direction of an axis of the brake drum body. According to the brake drum, intensity and rigidity of the brake drum are improved, heat dissipation area is enlarged, heat dissipation efficiency is improved, braking failure caused by thermal fatigue clapping of the brake drum is avoided and meanwhile service life of a tire is improved.
Description
Technical field
The utility model belongs to the vehicle brake technology field, relates in particular to a kind of brake drum.
Background technique
At present, brake drum can produce amount of heat because of friction in the process of work, heat is enclosed in the annular space of brake drum and wheel tyre bead, causes brake drum temperature too high, causes that the brake drum material tissue changes, thereby cause the be full of cracks of brake drum thermal fatigue, cause braking failure.
In addition, because brake drum temperature is too high, can cause tube to be heated for a long time, thereby produce aging working life of having reduced tire.
The model utility content
The purpose of this utility model is to provide a kind of brake drum, to solve the technical problem that the brake drum heat radiation is bad, intensity is low, working life is short.
The utility model is to realize like this, brake drum, comprise brake drum drum body, the external circumferential surface of described brake drum drum is provided with several rhombus projections, be provided with a vertical muscle with respect to described brake drum drum surface projection between the two adjacent described rhombus projections, described vertical muscle is consistent with the bearing of trend of the bulging body axis of described brake drum.
As a kind of improvement, described vertical muscle has eight, and eight described vertical muscle are evenly distributed on the external peripheral surface of described brake drum drum body.
As further improvement, make progress in the footpath of described brake drum, the maximum radius of described vertical muscle is less than the maximum radius of described rhombus projection.
The brake drum that the utility model provides, because the external circumferential surface of described brake drum drum is provided with several rhombus projections, be provided with a vertical muscle with respect to described brake drum drum surface projection between the two adjacent described rhombus projections, described vertical muscle is consistent with the bearing of trend of described brake drum drum body axis, thereby intensity, the rigidity of brake drum have not only been improved, and increased heat diffusion area, improved radiating efficiency, the braking failure that causes owing to the be full of cracks of the thermal fatigue of brake drum, the working life of also having improved tire have simultaneously been avoided.
Because described vertical muscle has eight, article eight, described vertical muscle is evenly distributed on the external peripheral surface of described brake drum drum body, thereby the structure of brake drum is more reasonable, and brake drum drum body is stressed more even, further improve the intensity of brake drum drum body, prolonged the working life of brake drum.
Because the footpath at described brake drum makes progress, the maximum radius of described vertical muscle is less than the maximum radius of described rhombus projection, namely between two adjacent rhombus projections, formed a groove, thus brake drum when rotation the wind energy that drives enough discharge fast along vertical muscle, reduced noise.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure, 1, brake drum drum body, 2, the rhombus projection, 3, vertical muscle.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, brake drum, comprise brake drum drum body 1, brake drum drum body 1 external peripheral surface is provided with several rhombus projections 2, be provided with a vertical muscle 3 with respect to brake drum drum body 1 rat between the two adjacent rhombus projections 2, vertical muscle 3 is consistent with the bearing of trend of brake drum drum body 1 axis, and wherein vertical muscle 3 can arrange eight, and eight vertical muscle 3 are evenly distributed on the external peripheral surface of brake drum drum body 1.
Footpath at brake drum makes progress, and the maximum radius of vertical muscle 3 is less than the maximum radius of rhombus projection 2.
The brake drum that the utility model provides, because brake drum drum body 1 external peripheral surface is provided with several rhombus projections 2, be provided with a vertical muscle 3 with respect to brake drum drum body 1 rat between the two adjacent rhombus projections 2, vertical muscle 3 is consistent with the bearing of trend of brake drum drum body 1 axis, thereby intensity, the rigidity of brake drum have not only been improved, and increased heat diffusion area, improved radiating efficiency, the braking failure that causes owing to the be full of cracks of the thermal fatigue of brake drum, the working life of also having improved tire have simultaneously been avoided.
Because vertical muscle 3 has eight, article eight, vertical muscle 3 is evenly distributed on the external peripheral surface of brake drum drum body 1, thereby the structure of brake drum is more reasonable, and brake drum drum body 1 is stressed more even, further improve the intensity of brake drum drum body 1, prolonged the working life of brake drum.
Because the footpath at brake drum makes progress, the maximum radius of vertical muscle 3 is less than the maximum radius of rhombus projection 2, namely between two adjacent rhombus projections 2, formed a groove, thus brake drum when rotation the wind energy that drives enough discharge fast along vertical muscle 3, reduced noise.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1. brake drum, comprise brake drum drum body, the external circumferential surface of described brake drum drum is provided with several rhombus projections, it is characterized in that, be provided with a vertical muscle with respect to described brake drum drum surface projection between the two adjacent described rhombus projections, described vertical muscle is consistent with the bearing of trend of described brake drum drum body axis, makes progress in the footpath of described brake drum, and the maximum radius of described vertical muscle is less than the maximum radius of described rhombus projection.
