Description
Technical field
The utility model belongs to brake system of car component technical field, particularly relates to a kind of ring muscle brake drum.
Background technique
Braking system is one of important composition system of automobile, and at present, in truck field, widely used is adopt traditional cast inblock drum brake.
In prior art, typical drum brake comprises brake drum and brake shoe composition, and brake shoe can contact with the inner side surface of brake drum.Brake drum is in rotary state in vehicle traveling process, and when needs brake, brake shoe presses under the action of the braking force on brake drum, utilizes the surface friction drag between brake drum, thus makes car deceleration or the parking of traveling, to ensure traffic safety.
When automobile heavy-load, run at high speed time, especially when lower long slope or abrupt slope, owing to needing the braking of larger braking force and continuous several times to ensure that automobile is in controllable state, brake drum inner wall temperature is sharply raised, the internal-external temperature difference of brake drum strengthens, and causes the mechanical behavior under high temperature forming brake drum material sharply to decline.Because traditional brake drum material is gray cast iron, gray cast iron has the typical characteristics that the low fragility of intensity is greatly grey cast iron, in order to reduce the negative effect that these characteristics are brought, the wall thickness of brake drum must do very thick in ensure that brake drum has higher structural strength.But the wall thickness of brake drum is larger, internal-external temperature difference during brake drum braking is larger, and the temperature difference strengthens the temperature difference stress caused and adds that the mechanical behavior under high temperature of material worsens, and often causes brake drum inwall to develop into be full of cracks by longitudinal fine fisssure, so that last brake drum cracking.Therefore, traditional cast-in-block brake drum is shorter for working life.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of ring muscle brake drum, to solve the technical problem that existing brake drum Safety performance is low, working life is short.
For solving the problems of the technologies described above, the technical solution of the utility model is:
Ring muscle brake drum, comprise the brake drum body that cast iron materials is made, the outer surface of described brake drum body is provided with the stiffening rib that some and described brake drum body is wholely set, and described stiffening rib be arranged in parallel, and the height of described stiffening rib successively decreases from neutral position to both sides.
Improve as one, described brake drum body is provided with some through holes.
After have employed technique scheme, the beneficial effects of the utility model are:
Because ring muscle brake drum comprises the brake drum body that cast iron materials makes, the outer surface of brake drum body is provided with some stiffening ribs be wholely set with brake drum body, the structural strength of brake drum body can be improved, add the intensity of middle braking surface, thermal deformation resistant ability is stronger, improve mechanical property and Security, extend the working life of brake drum.
Because stiffening rib be arranged in parallel, and the height of stiffening rib successively decreases from neutral position to both sides, the power that brake drum body is subject to when braking can be successively decreased from neutral position to both sides, the height of stiffening rib successively decreases from neutral position to both sides setting, make the height of stressed large position stiffening rib high, the layout of stiffening rib is consistent with brake drum stress, can either alleviate the weight of brake drum, save material, can ensure again the Security of brake drum body.
Because brake drum body is provided with some through holes, the thermal diffusivity of brake drum can being strengthened, with making water directly enter in the body of casting during water cooling, increasing cooling effect.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, 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 explain the utility model, and be not used in restriction the utility model.
Fig. 1 is the structural representation of the ring muscle brake drum that the utility model embodiment one provides, Fig. 2 is the sectional view of Fig. 1, and Fig. 3 is the structural representation of the utility model embodiment two, and Fig. 4 is the sectional view of Fig. 3, for convenience of explanation, the part relevant to the utility model is only gived in figure.
Embodiment one:
As depicted in figs. 1 and 2, the ring muscle brake drum that embodiment one provides, comprise the brake drum body 1 that cast iron materials is made, the outer surface of brake drum body 1 is provided with some stiffening ribs 101 be wholely set with brake drum body 1, can improve the structural strength of brake drum body 1, add the intensity of middle braking surface, thermal deformation resistant ability is stronger, improve mechanical property and Security, extend the working life of brake drum.
Stiffening rib 101 be arranged in parallel, and the height of stiffening rib 101 successively decreases from neutral position to both sides, the power that brake drum body 1 is subject to when braking can be successively decreased from neutral position to both sides, the height of stiffening rib 101 successively decreases from neutral position to both sides setting, make the height of stressed large position stiffening rib 101 high, the layout of stiffening rib 101 is consistent with brake drum stress, can either alleviate the weight of brake drum, save material, can ensure again the Security of brake drum body 1.
Embodiment two:
As shown in Figure 3 and Figure 4, the ring muscle brake drum that embodiment two provides is substantially identical with the ring muscle brake drum structure that embodiment one provides, difference is: brake drum body 1 is provided with some through holes 2, the thermal diffusivity of brake drum can be strengthened, with making water directly enter in the body of casting during water cooling, increase cooling effect.
In the ring muscle brake drum that the utility model provides, the sectional shape of stiffening rib can be square, triangle or other shapes, at this not in order to limit the utility model.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
