Description
Technical field
The utility model relates to a kind of motor car accessories, is specifically related to a kind of split steel construction motor vehicle brake drum.
Background technology
Conventional motor vehicle brake drum adopts grey iron casting one-shaping technique, and when vehicle needs braking, driver steps on braking footrest, adopts oil or vapour to conduct to brake assembly, makes the brake assembly in brake drum and brake drum friction, reach the object of car brakeing.And braking can be used continuously when road conditions descending, brake drum heating, high temperature can be made, water for cooling must be watered to it, to ensure that vehicle can not produce the problem of brake failure by Yin Gaowen, when brake drum high temperature repeatedly, water in water for cooling use, ash iron construction is understood difference variation and breaks, the fritter gray iron casualty accident making motor vehicle brake malfunctioning or broken occurs, and therefore the traditional braking drum life-span is shorter, poor safety performance, and want integral replacing brake drum under brake drum loss to a certain extent under common situations, consumptive material is large, and production cost is high, causes the serious waste of resource.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art part, a kind of novel motor vehicle brake drum is provided, this brake drum adopts split Steel Structural Design, with electric welding and the fixed mode of rivet rivet clasp, rapid heat dissipation, intensity is high, good toughness, not easily broken, improve the service life of brake drum, and certain protective action can be played to tire.Technical scheme: a kind of split steel construction motor vehicle brake drum, comprise bulging shell and the gray iron inner sleeve double-layer structure of cast steel, described gray iron inner sleeve is installed on bulging shell inwall, and is fixed together by rivet with drum shell inwall.
Preferably, described bulging shell is Split type structure, comprises drum top and drum body, and described drum top is fixedly connected with through welding procedure with drum body, and gray iron inner sleeve is installed on bulging body annular inner wall through rivet.
Preferably, described gray iron inner sleeve is the compressing sleeve structure of overall cast iron, fixing docile and obedient on drum body annular inner wall through rivet entirety.
Preferably, described gray iron inner sleeve comprises some grey iron plates, and each grey iron plate is all fixedly connected with drum shell inwall through rivet.
Beneficial effect: 1, grey iron plate is effectively combined with steel construction by the utility model, outside employing steel design, intensity is high, good toughness, not easily fragmentation.Internal layer adopts gray iron inner sleeve, and effectively strengthen braking effect, relative to traditional grey iron casting one-shaping technique, production cost is lower, and braking effect is better, longer service life.
2, adopt split Steel Structural Design, accomplish that modularization is used, which part is bad, changes which part, and reduce use cost, the damaged location that in routine use, brake drum is common is top and inter deterioration.The utility model structure can be accomplished that top is bad and be changed top, and inner sleeve easy to wear is interchangeable, and needs integral replacing when need not break down as traditional brake drum, and consumptive material is few, and the secondary that can realize drum sub-assembly of parking brake uses, and makes resource obtain maximum using, energy-conserving and environment-protective.
3, brake drum skin adopts steel construction, and heat conduction is fast, protection tire, and brake assembly can prevent the brake failure problem because brake drum high temperature occurs.
4, brake drum internal layer adopts monoblock type ash iron plate, relative to the grey iron plate of separate assembling, can effectively prevent gap between split type grey iron plate to the additional wear of brake block, available protecting brake block.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
Embodiment 1: a kind of split steel construction motor vehicle brake drum, see Fig. 1, comprise bulging shell 1 and gray iron inner sleeve 4 double-layer structure of cast steel, described gray iron inner sleeve 4 comprises some grey iron plates, each grey iron plate is all fixedly connected with drum shell 1 inwall through rivet 5, and rivet is steel rivet.In the present embodiment, drum shell is formed in one structure, drum shell adopts double-decker pattern to combine the advantage of gray iron and cast steel, while not reducing brake drum braking quality, improves the intensity of brake drum, toughness and thermal conductivity, not easily broken during use, improve the bulk life time of brake drum.Due to traditional bolt nut type of attachment, when disassembled, along with the machinery of the instruments such as hammer beats, screw can be caused to expand, distortion, after cast steel shell is separated with gray iron inner sleeve, cast steel shell can not realize secondary and use, and the present embodiment adopts rivet form dexterously, rivet inserts in installing hole, after the extruding of rivet two ends, rivet both ends of the surface broaden, just fixing dead with installing hole, now cast steel shell and gray iron inner sleeve are closely fixed by rivet, when moving back rivet, blunderbuss can be utilized, one large one small, aim at rivets central firmly to pound, rivet is exited from installing hole, because installing hole is not threaded, rivet fills tighter with borehole jack when installing, after exiting, basic guarantee installing hole is indeformable, the secondary that can realize cast steel shell uses.The present embodiment is maximized make use of efficient resource, reduces maintenance cost, realizes recycling of shell, energy-conserving and environment-protective.
Embodiment 2: another kind of split steel construction motor vehicle brake drum, see Fig. 2 and Fig. 3, the present embodiment content is substantially identical with embodiment 1 content, same section content no longer repeats, as different from Example 1: the shell 1 of drum described in the present embodiment is Split type structure, comprise bulging top 2 and drum body 3, described bulging top 2 is fixedly connected with through welding procedure with drum body 3.Gray iron inner sleeve 4 is installed on bulging body 3 annular inner wall through rivet 5.This movable installation form, relative to traditional integrated formed structure, production cost reduces, and technique simplifies, and when breaking down in drum top or drum body, can realize local replacing, realize recycling of parts.Be specially: body, drum top cutting and separating will be roused along pad, and displace trouble unit, directly again weld after the parts more finished changing.Relative to traditional maintenance mode needing integral replacing, greatly reduce maintenance cost, maximizedly make use of efficient resource, environmental protection and economy, change the production technology of traditional braking drum, there is very high social value and economic worth.
Embodiment 3: another kind of split steel construction motor vehicle brake drum, see Fig. 4, the present embodiment content is substantially identical with embodiment 2 content, same section content no longer repeats, as different from Example 2: in the present embodiment, gray iron inner sleeve is the compressing sleeve structure of overall cast iron, fixing docile and obedient on drum body 3 annular inner wall through rivet entirety.The secondary that this version better can realize brake drum uses, and reduces the additional wear that brake block causes because of the butt seam between scattered grey iron plate, corner angle, can better protect brake block, improves braking ability.
