Abstract
The utility model discloses a reinforced type brake drum which comprises a brake drum body. One side circumferential face, close to the open end, of the brake drum body is provided with a first reinforcing strip, a second reinforcing strip is arranged on the part, at the left end of the first reinforcing strip, on the circumferential face of the brake drum body, the thickness of the second reinforcing strip is smaller than that of the first reinforcing strip, the two ends of the first reinforcing strip are in circular arc transition with the brake drum body and the second reinforcing strip respectively, and the left end of the second reinforcing strip is in circular arc transition with the brake drum body. The strength of the reinforced type brake drum is further enhanced, the deformation, caused by stress, of the brake drum is reduced, and meanwhile heat dissipation of the brake drum is facilitated; the pattern draft of the outer circumference of the brake drum body is increased, the strength of the brake drum is increased, the strength of the brake drum is improved, and the service life of the brake drum body is obviously prolonged.
Description
Technical field
The utility model relates to a kind of vapour vehicle component, particularly a kind of for heavily blocking the reinforced brake drum on brake system of car.
Background technique
Brake drum is the vital part that heavily blocks brake system of car, as shown in Figure 1, existing brake drum comprises brake drum body 1, for preventing the distortion of brake drum body 1 uncovered end, in the uncovered end of brake drum body 1, excircle is provided with a circle reinforcing strip 2, the thickness H1 of reinforcing strip 2 is 9.5mm, the axial length of reinforcing strip 2 is L1=41mm, reinforcing strip 2 edges apart from brake drum body 1 open-mouth end distance L 2=28mm, arc transition between reinforcing strip 2 both sides and brake drum body 1, the pattern draft A of brake drum body 1 is 0.5 °.The said structure of brake drum body 1 produces distortion because open-mouth end is stressed compared with great Yi when work, because brake drum material is high strength cast iron, compared with large distortion, easily causes the open-mouth end cracking of brake drum and loses efficacy.
Model utility content
The utility model is in order to solve deficiency of the prior art, provide a kind of pattern draft large, there is double-deck reinforcing strip, high, the on-deformable reinforced brake drum of intensity.
For achieving the above object, the utility model proposes following technological scheme: a kind of reinforced brake drum, comprise brake drum body, brake drum body is provided with the first reinforcing strip closing on a side circumferential surface of open-mouth end, the circumferential surface of described brake drum body is provided with the second reinforcing strip at the left end of the first reinforcing strip, the thickness of the second reinforcing strip is less than the thickness of the first reinforcing strip, the first reinforcing strip two ends arc transition respectively and between brake drum body and the second reinforcing strip, arc transition between the left end of the second reinforcing strip and brake drum body.
The pattern draft of the brake drum body circumferential surface in described the second reinforcing strip left side is 1.0 °-1.5 °.
The pattern draft of the brake drum body circumferential surface in described the second reinforcing strip left side is 1.5 °.
Described brake drum body, the first reinforcing strip and the second reinforcing strip integrally casting moulding, the right-hand member of the first reinforcing strip apart from brake drum body open-mouth end distance be 28mm, the axial length of the first reinforcing strip is 65mm, the thickness of the first reinforcing strip is 5.5mm, the axial length of the second reinforcing strip is 30mm, and the thickness of the second reinforcing strip is 5mm.
Adopt technique scheme, owing to having set up the second reinforcing strip on brake drum body, and lengthened the axial length of the first reinforcing strip, further strengthen the intensity of brake drum, reduce brake drum because of the stressed distortion producing, be conducive to the heat radiation of brake drum simultaneously, the pattern draft of the brake drum body excircle increasing in addition, improved the intensity of brake drum, be significantly improved the working life of brake drum body.The utility model is reasonable in design, simple in structure, designs in advance mould, brake drum body, the first reinforcing strip and the second reinforcing strip integrally casting moulding.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
Embodiment
Shown in Fig. 2, a kind of reinforced brake drum of the present utility model, comprise brake drum body 1, brake drum body 1 is provided with the first reinforcing strip 3 closing on a side circumferential surface of open-mouth end, the circumferential surface of brake drum body 1 is provided with the second reinforcing strip 4 at the left end of the first reinforcing strip 3, the thickness of the second reinforcing strip 4 is less than the thickness of the first reinforcing strip 3, the first reinforcing strip 3 two ends arc transition respectively and between brake drum body 1 and the second reinforcing strip 4, arc transition between the left end of the second reinforcing strip 4 and brake drum body 1.
The pattern draft A of brake drum body 1 circumferential surface in the second reinforcing strip 4 left sides is 1.0 °-1.5 °, preferably 1.5 °.
Brake drum body 1, the first reinforcing strip 3 and the second reinforcing strip 4 integrally casting moulding, the right-hand member of the first reinforcing strip 3 apart from brake drum body 1 open-mouth end distance L 2 be 28mm, the axial length L 1 of the first reinforcing strip 3 is 65mm, the thickness H1 of the first reinforcing strip 3 is 5.5mm, the axial length L 3 of the second reinforcing strip 4 is 30mm, and the thickness H2 of the second reinforcing strip 4 is 5mm.
The present embodiment is not done any pro forma restriction to shape of the present utility model, material, structure etc.; any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all belong to the protection domain of technical solutions of the utility model.
