Abstract
The utility model provides a brake drum of an automobile. The brake drum comprises a mounting disc and a barrel which are integrally formed. Mounting bolt holes and a shaft hole are arranged on the mounting disc, the inner surface of the barrel is a brake friction surface, an annular boss is arranged on the side, which is close to an opening of the barrel, of the outer surface of the barrel, an annular first groove is arranged on one side of the annular boss, and an annular second groove is arranged at the opening of the barrel. The brake drum has the advantages that the brake drum is symmetrical in structural design and favorable for manufacturing and installation, and is stressed uniformly after being installed, a wheel can be effectively braked by the brake drum, and the service life of the brake drum can be prolonged.
Description
Technical field
The utility model belongs to the automobile brake field, particularly a kind of brake drum of automobile.
Background technique
Vehicle deceleration even parking in the automobile running must be installed braking device on vehicle, so that the driver can apply control to vehicle according to situations such as road and traffic, brake, thereby make the vehicle deceleration or the parking of travelling, to guarantee traffic safety.The used break overwhelming majority of known braking device utilizes the friction of fixed element rotatable member working surface and produces braking moment, is called friction brake, can be divided into drum-type and disc type two big classes.The critical piece brake drum manufacturing process of drum brake is a casting, and machining is installed and reached installation requirement then.Because casting technique, technical merit and effect of material performance, the brake drum surface irregularity, and defectives such as sand holes, loose, shrinkage cavity are arranged, cause brake drum can not form dynamic balancing preferably when rotated.When vehicle heavy duty or run at high speed, especially braking device is frequent when descending uses and stressed excessive, and the phenomenon that can take place to burst suddenly makes brake failure and causes the accident.
The model utility content
At defective that exists in the prior art and deficiency, it is a kind of simple in structure, easy for installation that the utility model embodiment provides, and the brake drum of the automobile of good braking effect.
In order to achieve the above object, the utility model proposes a kind of brake drum of automobile, comprise integrated installation disk body and cylindrical shell, described installation disk body is provided with construction bolt hole and axis hole, described cylinder inner surface is a brake area, close cylindrical shell oral area one side of described barrel outer surface is provided with the projection of an annular, and projection one side of described annular is provided with first groove of annular, and described cylindrical shell oral area is provided with second groove of annular.
Preferential as technique scheme, described construction bolt hole is more than one and around being arranged at the axis hole circumference.
The utility model proposes a kind of brake drum of automobile, comprise integrated installation disk body and cylindrical shell, described installation disk body is provided with construction bolt hole and axis hole, described cylinder inner surface is a brake area, described barrel outer surface is provided with the projection of an annular near cylindrical shell oral area one side, projection one side of described annular is provided with first groove of annular, and described cylindrical shell oral area is provided with second groove of annular.。Its structural design is well-balanced, is beneficial to make and install, and is stressed even after installing, and can be good at realizing the braking of wheel, and can prolong the working life of brake drum.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.For the person of ordinary skill in the field, to the detailed description of the present utility model, described and other purposes of the present utility model, feature and advantage will be apparent.
Description of drawings
Fig. 1 dissects structural representation for preferred embodiment of the present utility model.
Fig. 2 is the side view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The brake drum of a kind of automobile that the utility model proposes, as shown in Figure 1 and Figure 2, comprise integrated installation disk body 1 and cylindrical shell 2, described installation disk body 1 is provided with construction bolt hole 4 and axis hole 3, described cylindrical shell 2 internal surfaces are brake area, close cylindrical shell oral area one side of described cylindrical shell 2 outer surfaces is provided with protruding 5 an of annular, and projection 5 one sides of described annular are provided with first groove 6 of annular, and described cylindrical shell oral area is provided with second groove 7 of annular.
Described construction bolt hole 4 is more than one and around being arranged at axis hole 3 circumference.
Certainly; the utility model also can have other embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; the person of ordinary skill in the field works as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of claim of the present utility model.
