Abstract
The utility model relates to an embedded brake drum, which relates to a brake drum structure. The embedded brake drum is formed by that when the brake drum is cast, a cylinder annular ring formed by processing a steel plate is embedded on a long cylinder of a pure casting of the brake drum, thereby, the appearance of the brake drum is caused to be smooth, clean and beautiful; the dynamic balance is good when the brake drum is rotated, and the strength and the comprehensive mechanical property of the position of the long cylinder are effectively improved, which causes the casting not to easy to burst, the service life to be prolonged and the use safety to be enhanced.
Description
Technical field
The utility model relates to a kind of brake drum structure.
Background technique
At present, existing motor vehicle brake drum processes with pure foundry goods.The brake drum that this structure constitutes is subjected to factor affecting such as material property, casting technique, technical merit, casting surface is uneven in addition sand holes arranged, scab, defective such as caking, and easily cause brake drum dynamic balancing when rotated poor; In the motor vehicle running process, brake drum frequency of utilization height, foundry goods bursts because of the attenuation gradually that rubs easily causes, and working life is short, security incident is many.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned defective, a kind of edge formula brake drum being provided.
Scheme of the present utility model is: in the casting brake drum, the cylindrical body annular ring that steel plate is processed is set in the elongated cylinder external layer of the pure foundry goods of brake drum, becomes edge formula brake drum.
The utility model has the advantages that: the cylindrical body annular ring that steel plate processes is set in the pure foundry goods elongated cylinder of brake drum external layer, and profile is bright and clean attractive in appearance, and when rotation good dynamic balance; Foundry goods has been reinforced the cylindrical body annular ring, has improved the intensity and the comprehensive mechanical property at the elongated cylinder position of brake drum, makes foundry goods be difficult for bursting, and has prolonged working life, has strengthened safety in utilization.
Description of drawings
Fig. 1 is a front section view of the present utility model
Fig. 2 is the plan view of Fig. 1
Among the figure: the 1st, the pure foundry goods of brake drum, the 2nd, cylindrical body annular ring.
Embodiment
The utility model is to implement like this, and it is made up of the pure foundry goods of brake drum and two parts of cylindrical body annular ring:
Embodiment 1: steel plate becomes the cylindrical body annular ring (2) that internal diameter equates with brake drum foundry goods cylindrical body external diameter through cutting, volume circle, butt welding; Cylindrical body annular ring (2) is put in the casting moulding box of brake drum, in casting brake drum foundry goods, cylindrical body annular ring (2) is set on the pure foundry goods elongated cylinder of brake drum, promptly become edge formula brake drum.
Embodiment 2: steel plate becomes cylindrical body annular ring (2) through cutting, volume circle, butt welding behind through hole; Cylindrical body annular ring (2) is put in the casting moulding box of brake drum, in casting brake drum foundry goods, cylindrical body annular ring (2) is set on the pure foundry goods elongated cylinder of brake drum, promptly become edge formula brake drum.
Shape of through holes can be set at square, or rectangular, or oval, or circular.
Upper installing is decided to be even distribution to through hole in same cross section.
Cylindrical body annular ring height setting is the height that is less than or equal to the brake drum elongated cylinder.
Embodiment 3: steel plate utilizes the die stamping cylindrical body annular ring outside through cutting, volume circle, to postwelding, at the inboard boss that forms of ring, becomes the cylindrical body annular ring (2) of band boss.To put in the casting moulding box of brake drum with boss cylindrical body annular ring (2), in casting brake drum foundry goods, cylindrical body annular ring (2) will be set on the pure foundry goods elongated cylinder of brake drum, promptly become edge formula brake drum.
The boss shape is set at various stero shapes.
Boss is evenly to distribute in same horizontal section set positions.
Claims (4)
1, edge formula brake drum is made up of the pure foundry goods of brake drum and two parts of cylindrical body annular ring, and it is characterized in that: the cylindrical body annular ring is set in the elongated cylinder external layer of the pure foundry goods of brake drum.
2, edge formula brake drum according to claim 1 is characterized in that: the height setting of cylindrical body annular ring is not for being higher than the height of brake drum elongated cylinder.
3, edge formula brake drum according to claim 1, it is characterized in that: the shape of through holes of cylindrical body annular ring can be set at square, or rectangular, or oval, or circular.
4, edge formula brake drum according to claim 1 is characterized in that: the through hole of cylindrical body annular ring is upper in same cross section to be changed to even distribution.
