Description
Technical field
The utility model relates to a kind of automobile brake drum, belongs to technical field of automobile parts.
Background technique
The similar peviform of bulging shape of general automobile brake drum, one end is the brake drum drum end, the other end is opening-like, usual automobile brake drum is that gray iron material Mechanical processing of casting forms, for the brake drum that the bore of a vapour liberation dumping car adapted is φ 410, its bearing capacity is 165 tons, the wall thickness of brake drum opening end is up to 30mm, and the wall thickness of brake drum retarder location is about 19mm, this design is adopted to be mechanical strength in order to ensure brake drum and load-carrying properties, more in order to avoid the potential safety hazard in using process.But opening wall thickness and retarder location place Wall-Thickness Difference larger, easily form stress at transition position and concentrate step and casting defect, under the effect of heat and braking force, easily ftracture or chap in brake drum drum body opening shape one end, cause reduce the working life of automobile brake drum, thus vehicle traveling can be affected; Although simultaneously brake drum wall thickness is thicker ensure that bulk strength, brake drum poor radiation can be caused simultaneously, and grey ironware reach uniform temperature after mechanical property can obviously decline.In vehicle actual travel process, the frequency of utilization of brake drum is high, certainly can make automobile brake drum by adopting the alloy materials such as steel, although drum body opening shape one end can be avoided to ftracture or to chap, but because its material therefor makes drum body cost high, generally all can not accept; Can improve bulging body Problems existing by the mode of the wall thickness increasing brake drum drum body in addition, although can play certain anti-crack function, brake drum overall dimensions can strengthen, and impact is installed and used.
Summary of the invention
The deficiency that the utility model exists for above-mentioned prior art, provide a kind of structure simple, the automobile brake drum that tensile strength improves, it not only has good radiating effect, and braking ability is good, improves traffic safety performance.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of automobile brake drum, comprise brake drum drum body, the braking outer peripheral surface of described brake drum drum body is evenly placed with the stiffening rib of multiple projection, described stiffening rib is the straight line muscle of spiral bar or the axis being parallel with described brake drum drum body, the outer surface of described stiffening rib is provided with an annular strap, the axis of described annular strap is consistent with the axis of described brake drum drum body, described annular strap, multiple heat dissipation channel is formed between stiffening rib and brake drum drum body, described annular strap, stiffening rib and described brake drum drum body are integrated cast structure.
Further, the width of described annular strap is 1 ~ 300mm.
Further, the width numerical value of described annular strap is preferably 50 ~ 240mm.Both proof strength, again can and brake drum drum body between form interlayer heat dissipation channel and facilitate wind-guiding, improve the radiating efficiency of brake drum.
Further, the interior circular diameter of described annular strap is less than the external frame place diameter of a circle of described stiffening rib.Make annular strap be embedded in the outside of stiffening rib, and can interlayer be formed, convenient heat radiation.
Further, the transverse section of described annular strap is rectangle.Improve annular strap and brake drum bulk strength.
Further, described stiffening rib is 0 ~ 300mm from the distance of brake drum opening end.
Further, described stiffening rib is 5 ~ 70mm from the distance of brake drum opening end.Different braking drum installation requirements can be adapted to.
Further, the quantity of described stiffening rib is 1 ~ 50.Gain in strength and coordinate annular strap to form interlayer heat dissipation channel and be beneficial to heat radiation.
15 spiral bars are provided with brake drum external peripheral surface,, an annular strap, the width of annular strap is 200mm, the brake drum that stiffening rib is 10mm apart from the distance of brake drum opening end is example, the wall thickness of its brake drum drum body is 14mm, and the overall weight of brake drum is about 61kg, and institute's bearing capacity is about 210 tons, improve 27%, integral heat sink area 1.264m
2improve 31%.
Generally speaking, adopt the brake drum of technique scheme, the wall thickness of its brake drum drum body is 10 ~ 15mm, and the overall weight of brake drum is about 55 ~ 65kg, and institute's bearing capacity is about 205 ~ 220 tons, and integral heat sink area is 1.1 ~ 1.35m
2.
The beneficial effects of the utility model are: the braking external peripheral surface of automobile brake drum arranges multiple stiffening rib, can be helical also can be the straight line shape consistent with brake drum axis, the outer surface of stiffening rib is provided with annular strap, under the effect that stiffening rib supports, sandwich structure between annular strap and brake drum drum body forms heat dissipation channel, improve brake drum intensity simultaneously, increase thermal diffusivity.This brake drum decreases the probability because heat and Braking make brake drum ftracture, be out of shape, keep brake drum and the good laminating of brake shoe, the structure and the integral heat sink area that are beneficial to heat dissipation channel wind-guiding increase simultaneously, effectively can lower break drum temperature, reduce the heat effects to steel ring and tire, improve the working life of brake drum, friction plate and tire, effectively prevent from, due to brake drum be full of cracks, tyre explosion and the accident that causes, improve the Security of driving.
