Abstract
The utility model discloses a kind of novel drum brakes, at the bottom of comprising hub body, hub, hub wall, central siphon, brake block, it is characterized in that: hub body is round structure; Hub body surrounding is provided with 4 screw fixed holes, and brake block is provided with oblique fluting; At the bottom of hub, be circular; Gu Di center is provided with central siphon, in hub body, is provided with through hole; Described through hole can be also the oblique through hole between being arranged at the bottom of hub wall and hub for being arranged on radial direction through hole on hub wall.The beneficial effects of the utility model are as follows: during tyre rotation, wheel hub is inner can produce negative pressure, is provided with through hole in wheel hub, the hot air in wheel hub can be separated out outside wheel hub, thereby unavoidably long-time apply the brakes cause the situation of overheating wheel.
Description
Technical field
The utility model relates to braking device, particularly a kind of novel drum brakes.
Background technique
The main traffic instrument that people use at present be take automobile, motorcycle as main, and the brake system of these traffic tool mainly be take butterfly brake, drum brakes and disk type brake as main.
Existing drum brakes, owing to being the system of sealing, causes the dust producing after brake disc friction cannot get rid of brake system, uses for a long time, can cause drum brakes inside temperature too high, affects braking effect.
Prior art, referring to shown in Fig. 1-2, is enclosed construction at the bottom of hub, is plane structure on brake block.
Model utility content
In order to solve deficiency of the prior art, the utility model proposes a kind of novel drum brakes.The technological scheme adopting is as follows:
A novel drum brakes, at the bottom of comprising hub body, hub, hub wall, central siphon, brake block, is characterized in that: hub body is round structure; Hub body surrounding is provided with 4 screw fixed holes, and brake block is provided with oblique fluting; At the bottom of hub, be circular; Gu Di center is provided with central siphon, in hub body, is provided with through hole.
Further, described through hole can be for being arranged on the radial direction through hole on hub wall.
Further, described through hole can be the oblique through hole between being arranged at the bottom of hub wall and hub.
The beneficial effects of the utility model are as follows:
During tyre rotation, wheel hub is inner can produce negative pressure, is provided with through hole in wheel hub, the hot air in wheel hub can be separated out outside wheel hub, thereby unavoidably long-time apply the brakes causes the situation of overheating wheel.
Accompanying drawing explanation
Fig. 1 is the hub body structure figure of prior art;
Fig. 2 is the brake block structure figure of prior art;
Fig. 3 is hub body structure figure of the present utility model;
Fig. 4 is brake block structure figure of the present utility model;
Fig. 5 is the sectional drawing of the utility model radial direction through hole;
Fig. 6 is the sectional drawing of the oblique through hole of the utility model;
Reference character:
At the bottom of hub body 1, hub 11, hub wall 12, central siphon 13, brake block 14, radial direction through hole 15, oblique through hole 16, oblique fluting 17.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.
Embodiment one
A kind of novel drum brakes as shown in Fig. 3,4,5, comprises at the bottom of hub body 1, hub 11, hub wall 12, central siphon 13, brake block 14, it is characterized in that: hub body 1 is round structure; Hub body 1 surrounding is provided with 4 screw fixed holes, and brake block 14 is provided with oblique fluting 17; At the bottom of hub, 11 is circular; At Gu Di 11 centers, be provided with central siphon 13, in hub body 1, be provided with through hole; Described through hole can be for being arranged on the radial direction through hole 15 on hub wall.
During tyre rotation, wheel hub is inner can produce negative pressure, is provided with through hole in wheel hub, the hot air in wheel hub can be separated out outside wheel hub, thereby unavoidably long-time apply the brakes causes the situation of overheating wheel.
Further, described through hole can be the oblique through hole between being arranged at the bottom of hub wall and hub.
Embodiment two
A kind of novel drum brakes as shown in Fig. 3,4,6, comprises at the bottom of hub body 1, hub 11, hub wall 12, central siphon 13, brake block 14, it is characterized in that: hub body 1 is round structure; Hub body 1 surrounding is provided with 4 screw fixed holes, and brake block 14 is provided with oblique fluting 17; At the bottom of hub, 11 is circular; At Gu Di 11 centers, be provided with central siphon 13, in hub body 1, be provided with through hole; Described through hole can be the oblique through hole 16 between being arranged at the bottom of hub wall and hub.
During tyre rotation, wheel hub is inner can produce negative pressure, is provided with through hole in wheel hub, the hot air in wheel hub can be separated out outside wheel hub, thereby unavoidably long-time apply the brakes causes the situation of overheating wheel.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
