Abstract
The utility model relates to a synthetic brake drum, belonging to the brake device, comprising a drum body composed of a drum bottom and a drum tube, wherein the drum body is an integral drum body formed by spinning a steel plate and an abrasion resistance material layer is arranged on the inner tube of the drum tube. The tube wall of the drum tube is a wave-shaped structure and the abrasion resistance material layer is integrated with the inner wall of the drum tube by casting. The wall thickness is relative thin, so as to lighten the weight and increase the main body intensity and prevent heating to crack after long-time brake and also prevent casting defect and easy-deformation of the welding piece, its technology is relative simple, the appearance is relative beautiful, the abrasion resistant material is prevented from loosening and reutilizing and its use cost is relative low.
Description
Technical field
The utility model relates to a kind of braking device, particularly a kind of synthetic brake drum.
Background technique
Existing automobile brake drum all is grey cast iron material casting drum basically, wall thickness is big, pts wt is heavier, the difficult control of casting defect, easily generating heat under the long-time braking and cracking (particularly under dress dripping device situation), spoilage is higher, therefore some manufacturers adopt the method for welding to make brake drum, promptly be earlier steel plate to be made the bulging end and drum barrel respectively, and then will rouse the end and drum barrel is welded into an integral body, this brake drum has avoided pts wt heavily to reach casting defect shortcoming rambunctious preferably, but has also occurred complex process simultaneously, yielding deficiency.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of synthetic brake drum, with the Heavy Weight that solves brake drum, easy to crack, the difficult control of casting defect and problem yielding, complex process.
The technological scheme that solves the problems of the technologies described above is: a kind of synthetic brake drum, comprise the bulging body that constitutes by the drum end and drum barrel, and the integral type drum body of described bulging body for forming by steel plate spinning, and the inwall of drum barrel is provided with wear-resistant material layer.
Further technological scheme of the present utility model is: the barrel of described drum barrel is wavy structure.
Further again technological scheme of the present utility model is: the inwall of described wear-resistant material layer and drum barrel forms an integral body by casting.
Because adopt said structure, the synthetic brake drum of the utility model is compared with existing brake drum, has following beneficial effect.
Because the integral type drum body of bulging body of the present utility model for forming by steel plate spinning, its wall thickness is thinner, both alleviated weight, improved body intensity again, can avoid under long-time braking, generating heat and ftractureing, and avoid casting defect and the yielding defective of weldment, and because bulging body of the present utility model is that whole spinning forms, its technology is fairly simple, and profile is better appearance also.
In addition, because drum barrel barrel of the present utility model is wavy structure, this structure can prevent that wear-resistant material layer from getting loose, and because the inwall of wear-resistant material layer and drum barrel is to form an integral body by casting, therefore, after the utility model uses the long period, when braking surface is worn, recyclable brake drum wear-resistant material layer of casting again again can also utilize once more, thereby reduce user cost greatly.
Below, the technical characteristics to the synthetic brake drum of the utility model is further described in conjunction with the accompanying drawings and embodiments.
Description of drawings
Fig. 1: the structural representation of the synthetic brake drum of embodiment's one described the utility model,
Fig. 2: the structural representation of the synthetic brake drum of embodiment's two described the utility model,
Among the figure,
1-drum body, the 101-drum end, 102-drum barrel, 2-wear-resistant material layer.
Embodiment
Embodiment one:
Disclosed among Fig. 1 is a kind of synthetic brake drum, this brake drum comprises the bulging body 1 that is made of the drum end 101 and drum barrel 102, the integral type drum body of described bulging body 1 for forming by steel plate spinning, and the inwall of drum barrel 102 is provided with wear-resistant material layer 2, and described wear-resistant material layer 2 forms an integral body with the inwall of drum barrel 102 by casting.
Embodiment two:
Disclosed among Fig. 2 is another kind of synthetic brake drum, this brake drum comprises the bulging body 1 that is made of the drum end 101 and drum barrel 102, the integral type drum body of described bulging body 1 for forming by steel plate spinning, the barrel of described drum barrel 102 is wavy structure, and the inwall of drum barrel 102 is provided with wear-resistant material layer 2, and described wear-resistant material layer 2 forms an integral body with the inwall of drum barrel 102 by casting.
As a kind of conversion of embodiment one and embodiment two, described wear-resistant material layer 2 also can not be to form an integral body by casting with the inwall of drum barrel 102, but links together by other fit.
Claims (3)
1. synthetic brake drum, comprise the bulging body (1) that constitutes by the drum end (101) and drum barrel (102), it is characterized in that: the integral type drum body of described bulging body (1) for forming by steel plate spinning, and the inwall of drum barrel (102) is provided with wear-resistant material layer (2).
2. synthetic brake drum according to claim 1 is characterized in that: the barrel of described drum barrel (102) is wavy structure.
3. synthetic brake drum according to claim 1 and 2 is characterized in that: described wear-resistant material layer (2) forms an integral body with the inwall of drum barrel (102) by casting.
