Description
Technical field
The utility model relates to brake system of car component, particularly a kind of brake drum.
Background technique
Since 2010, complete more than 1800 of China's auto output, surmount the U.S. and leap to the first in the world, automobile pollution also reaches 1.2 hundred million, the extraordinary emergence of auto output brings prosperity and the confusion in auto parts machinery market, automobile brake drum is a strength member of automobile running system, it belongs to a part for car sedan-chair assembly, generally speaking, if brake drum genuine configures, working life can more than 100,000 kilometers, if and component market configures, often only have 50,000 kilometers, to truck, genuine configuration can reach 3.5 ten thousand kilometers even more, and the brake drum of component market is mostly below 30,000 kilometers, even less than 10,000 kilometers.
At present; the heat dispersion of brake drum is bad is the one of the main reasons causing the brake drum life-span short; if automobile is under the operating mode of long and steep downgrade; due to long skidding; cause brake drum seriously to generate heat, when not dispelling the heat in time, brake drum and associated components can produce distortion; cause brake failure, crisis traffic safety.For this reason, common way is directly brake drum cooling with cold water, and this way can cause each position of brake drum to occur phenomenon uneven in temperature, facilitates brake drum to occur crackle, accelerates the damage of brake part, reduces brake drum working life; Therefore the replacing of brake drum is very frequent, so not only wastes a large amount of financial resources, material resources, and more frighteningly in vehicle traveling process, brake drum lost efficacy the serious accident of the car crash that may cause.
In vehicle travel process, during brake, setting is opened with the brake shoe iron assembly of brake drum inside and is produced resistance with the surface friction of brake drum inner side surface and realizes braking, thus makes vehicle deceleration or the parking of traveling.Brake drum is due to severe friction, produce a large amount of heat energy, owing to expanding with heat and contract with cold, dispel the heat bad, brake drum very easily occurs losing round phenomenon, thus affect the working life of brake drum, therefore how to increase the heat dispersion of brake drum, the working life of raising brake drum and brake drum replacing have conveniently become an important technical barrier.
Model utility content
The purpose of this utility model is the shortcoming overcoming prior art, provides that a kind of thermal diffusivity is good, long service life and dead turn change brake drum easily.
The purpose of this utility model is achieved through the following technical solutions: a kind of brake drum, it comprises bulging shell and dead turn, described dead turn offers multiple tapped hole, dead turn is arranged on inside bulging shell by screw, described bulging shell surface is provided with interlaced rinforcement bar, described dead turn is two-layer up and down, every one deck dead turn is ring structure, the inner side surface of the every one deck of described dead turn is evenly equipped with for preventing dead turn from losing round wire casing because expanding with heat and contract with cold, and on, wire casing on lower two-layer dead turn staggers setting respectively, described bulging shell is also provided with the vent hole for ventilating, described vent hole is inclined hole.
Radial angle on described vent hole and its housing transverse section, place is 30 ° ~ 75 °.
Described wire casing offers the through hole communicated with vent hole, the gradient of this through hole and vent hole is consistent.
Described rinforcement bar is interconnected diamondwise.
The end face of described bulging shell is provided with fixed hole and center hole.
The utility model has the following advantages: bulging shell outer surface of the present utility model is provided with stiffening rib, add the heat diffusion area of brake drum, the existing bulging thickness of the shell of Thickness Ratio of the groove that simultaneously stiffening rib also can be made to surround reduces by 40 percent, thus add the heat dispersion of brake drum, improve the working life of brake drum; Arrange dead turn in drum shell, brake shoe iron assembly is not come in contact with drum shell, and drum shell is not easy to occur destroying, long service life, and is connected by screw between dead turn and drum shell, and dead turn is changed convenient, replacement cost greatly reduces; Dead turn is provided with wire casing, avoids the mistake circle phenomenon of expanding with heat and contract with cold produced, thus further improves the working life of brake drum; Drum shell is provided with the gradient vent hole of band, dead turn is provided with the through hole be communicated with vent hole, vent hole is in state against the wind all the time, adds the ventilation of vent hole, thus accelerates the radiating efficiency of brake drum, extends the working life of brake drum.

Embodiment
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As depicted in figs. 1 and 2, a kind of brake drum, it comprises bulging shell 1 and dead turn 2, in the present embodiment, described bulging shell 1 is made for ZG400 material, and the end face of described bulging shell 1 is provided with fixed hole 8 and center hole 9, described dead turn 2 offers multiple tapped hole 3, dead turn 2 is arranged on inside bulging shell 1 by screw, described bulging shell 1 surface is provided with interlaced rinforcement bar 4, in the present embodiment, described rinforcement bar 4 is interconnected diamondwise, be groove in the middle of rhombus, the wall thickness reduction 40 percent of the comparable existing bulging shell of wall thickness of groove part, reduce the quality of brake drum, be convenient to install, but also add the heat dispersion of brake drum, improve the usability of brake drum, described dead turn 2 is two-layer up and down, every one deck dead turn 2 is ring structure, the inner side surface of the every one deck of described dead turn 2 is evenly equipped with for preventing dead turn 2 from losing round wire casing 5 because expanding with heat and contract with cold, and on, wire casing 5 on lower two-layer dead turn 2 staggers setting respectively, the wire casing 5 arranged prevents the mistake circle of dead turn 2, thus substantially increase working life, as shown in Figures 2 and 3, described bulging shell 1 is also provided with the vent hole 6 for ventilating, described vent hole 6 is inclined hole, in the present embodiment, described vent hole 6 is 30 ° ~ 75 ° with the radial angle on its place housing 1 transverse section, further, described wire casing 5 offers the through hole 7 communicated with vent hole 6, this through hole 7 is consistent with the gradient of vent hole 6, vent hole 6 is all set to the inclined hole tilted towards automobile direction of advance, each vent hole 6 is made all to be in state against the wind, add the air quantity of vent hole 3, thus accelerate to distribute by the heat produced and the temperature reducing brake drum of braking, the air quantity part that vent hole 3 enters then enters brake drum inside by through hole 7, reduce the temperature of dead turn 2 internal surface, and through hole also can discharge friction waste residue while ventilation fan heat, extend the working life of brake drum.
