Abstract
The invention relates to a spiral ventilation radiating brake drum which comprises a brake drum body. A brake friction face is arranged in the middle of the brake drum body, 4-10 rows of radiating holes series evenly distributed spirally are formed in the brake friction face, each row of radiating hole series comprises 4-8 radiating holes, and each row of radiating hole series are arranged linearly in the cross section of the brake drum body. The brake drum is light in weight, reduces the steps in the radiating process aspect of the existing brake drum, reduces production cost and greatly improves the braking capability foremost.
Description
Technical field
The invention belongs to automobile brake part, be specifically related to the Novel brake drum of a kind of ventilation, rapid heat dissipation.
Background technique
In the drum brakes system of automobile, undertaken rubbing by the friction plate in break and brake drum and realize the braking of vehicle, in the brake process of automobile long-distance descending, the heat of brake drum not easily scatters and disappears, temperature can raise fast, and the too high meeting of temperature makes brake failure, causes major traffic accidents, therefore there is a lot of vehicle to be also furnished with for the water tank of lowering the temperature that drips to brake drum, but which again increases the weight of vehicle.The brake drum of prior art is generally ironcasting, and its deficiency is that inner and outer surface is level and smooth, causes braking force to be difficult to improve, brake sensitive not, and not easy heat radiation, during high temperature, the chance water capacity easily cracks.
Traditional brake drum external cylindrical surface is smooth surface or with reinforcing rib structure, a brake drum is had also on rubbing surface, to be provided with reinforcing rib structure, general this structure can only strengthen the thickness of brake drum or increase the quantity of stiffening rib, and cause brake drum overweight, manufacture cost increases.
In order to improve the radiating effect of brake drum, also have and stiffening rib is set to oblique line structure, as Chinese utility model patent CN2828433Y discloses a kind of radiation brake drum, the external cylindrical surface of brake drum is uniformly distributed by many protruding oblique ribs, this oblique rib is connected with brake drum external cylindrical surface.By this structure, increase the heat diffusion area of brake drum, cause air to flow, produce certain air cooling effect.But due to the employing of oblique stiffening rib, when brake drum rotates, will certainly produce certain windage, be unfavorable for entering and discharge of air, its radiating effect is poor.
Summary of the invention
Object of the present invention is exactly that a kind of spiral ventilates, heat radiating type brake drum in order to propose.This brake drum is lightweight, decreases the process step of existing brake drum at heat radiation process aspect, reduces cost of production, the most important thing is that stopping power improves greatly.
The technical solution used in the present invention: a kind of spiral ventilates, heat radiating type brake drum, it comprises brake drum, it is brake area in the middle part of described brake drum, described brake area is provided with equally distributed in the shape of a spiral radiation hole system, described radiation hole is 4-10 row, often arrange radiation hole system and have 4-8 radiation hole, often row's radiation hole ties up to and is arranged in a linear along on brake drum cross section.
Further, radiation hole casting together with brake drum of described radiation hole system, radiation hole diameter is 4-15mm.
The present invention compared with prior art its beneficial effect is: (1): invention increases braking force, makes brake sensitiveer; (2) the radiation hole system on brake drum can form airflow channel, improves heat dissipation rate, avoids temperature too high and the brake failure that causes, also can reduce high temperature and meet the quantity that water breaks, extend the working life of brake drum; (3) the present invention is owing to have employed the brake hole system of good braking effect, and brake drum weight is alleviated greatly, and casts to form together with brake drum due to the brake hole system on brake drum, cost of production is reduced, and meets the policy requirements of national energy-saving environmental protection.
