Abstract
The utility model relates to an automobile brake drum, and belongs to the technical field of automobile components. The automobile brake drum comprises a brake drum body, wherein meshed-net-shaped reinforcing ribs are arranged on the outer circumference surface of the brake drum body; at least one bar-shaped reinforcing rib parallel to the axial line of the brake drum body is arranged on the surface of the brake drum body, and is arranged on the cross-connection joints of the meshed-net-shaped reinforcing ribs; the height of each bar-shaped reinforcing rib is less than that of each meshed-net-shaped reinforcing rib; air valve grooves are formed at the intersection points of the bar-shaped reinforcing ribs and the meshed-net-shaped reinforcing ribs; and 2-6 bar-shaped reinforcing ribs are uniformly distributed on the outer circumference of the brake drum body. The automobile brake drum has the advantages that the structure is simple; the operation of mounting is convenient; the adding of the bar-shaped reinforcing ribs increases the mechanical strength of the air valve grooves, and enlarges the gap of a steel ring and the brake drum body, so that the heat radiating efficiency of the brake drum is improved, and therefore, the service life of the brake drum is prolonged, and the safety of a traveling crane is improved.
Description
Technical field
The utility model relates to a kind of automobile brake drum, and it belongs to technical field of automobile parts.
Background technique
The similar peviform of automobile brake drum drum body global shape, its surface is provided with the valve groove, and automobile brake drum is that pure foundry goods processes usually, in vehicle actual travel process, the frequency of utilization height of brake drum.Under the effect of heat and braking force, cracking or the be full of cracks easily of brake drum drum body, especially for the relative thinner valve groove of wall thickness, easier cracking often causes reduce the working life of automobile brake drum, travels thereby can influence vehicle; Certainly can make automobile brake drum by adopting alloy materials such as steel, though can avoid drum body opening shape one end can not to ftracture or chap, because of the feasible drum of its material therefor body cost height, generally all can not accept; In addition can be by increasing the thick problem of improving the existence of brake drum drum body of brake drum drum body wall, though can play certain anticracking effect, the brake drum overall dimensions can strengthen, influence is installed and used; In order to overcome above-mentioned deficiency, adopted the measure of establishing stiffening rib at the brake drum outer circumferential face, and the valve groove inevitably to pass stiffening rib, in the intersection of valve groove and stiffening rib, just formed a mechanical strength weak spot again, make easily brake drum herein stress concentrate and damage.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of automobile brake drum is provided, it can effectively solve the not enough problem of brake drum drum body local strength in valve groove and stiffening rib handing-over place generation, and guarantees that braking ability is good, improves the 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 comprises brake drum drum body, and the external circumferential surface of described brake drum drum is provided with latticed stiffening rib, is characterized in, at least also is provided with a strip stiffening rib parallel with described brake drum drum body axis on described brake drum drum surface.
Further, described strip stiffening rib is arranged on the crossbar contact of described latticed stiffening rib, and the height of described strip stiffening rib is less than the height of described latticed stiffening rib.The intersection point place of described strip stiffening rib and latticed stiffening rib has formed the valve groove.The degree of depth of described valve groove is the poor of described latticed stiffening rib and strip stiffening rib height.
Further, described strip stiffening rib is 2～6, is evenly distributed between the grid reinforcing rib of the external circumferential surface of described brake drum drum.Guarantee the balance of brake drum drum body, simultaneously easy for installation.
Further, described strip stiffening rib transverse section is approximate trapezoid.
Further, described brake drum drum body comprises opening end and flange end, and described opening end periphery is provided with the reference level outer rim, and described flange end periphery is provided with the arc outer rim, and described latticed stiffening rib is arranged between described reference level outer rim and the arc outer rim.
Further, described strip stiffening rib 2, latticed stiffening rib 3 are cast into integrative-structure with described brake drum drum body 1.
The beneficial effects of the utility model are: described strip stiffening rib is combined the valve groove that forms with latticed stiffening rib, because having adopted the strip stiffening rib in its bottom, strengthened the mechanical strength of brake drum drum body valve groove, reduced because heat and braking force effect make the probability of brake drum drum body cracking or distortion, a plurality of valve grooves are evenly distributed on brake drum drum surface, not only guarantee the balance of brake drum, and it is easy for installation, increased the gap of steel ring and brake drum drum body simultaneously, improved the radiating efficiency of brake drum, thereby prolonged the working life of brake drum, improved traveling security.
