Abstract
The invention discloses a brake drum and relates to the technical field of automobile parts. The brake drum comprises a barrel-shaped drum body. A connecting flange is arranged at one end of the drum body, and the other end of the drum body is an opening end. A reinforcing part for preventing the opening end of the drum body from cracking is sleeved on the outer surface of the drum body. According to the brake drum, a reinforcing part is additionally arranged on a reinforcing belt, so that the deformation of the brake drum is reduced, the possibility of cracking of the opening end of the brake drum is lowered, and the service life of the wheel brake drum is prolonged.
Description
Technical field
The present invention relates to technical field of automobile parts, particularly a kind of brake drum.
Background technique
Brake drum is one of automobile brake parts, belongs to the part of brake system, and during brake, piston is exerted pressure to two pairs of half-moon-shaped brake shoes, makes it be adjacent to the tympanum inwall, thereby produces the rotation that friction stops wheel.The material of brake drum is generally HT200-300 (gray cast iron), and this kind material can play heat radiation, increase frictional behaviour, reduce the effect of brake noise.At present, the production technology of brake drum blank is casting because brake drum is through the down and outside spreading of the effect of the brake shoes friction of being everlasting, thereby brake drum can be from drum body port cracking, influence the using effect and the working life of brake drum.
Summary of the invention
The present invention seeks to provides a kind of and can not produce cracking phenomena, the brake drum of long service life in order to overcome above-mentioned deficiency.
For solving the problems of the technologies described above; Technological scheme of the present invention is: a kind of brake drum, comprise tubular drum body, and an end of said bulging body is provided with adpting flange; The other end of said bulging body is an opening end, and the outer surface of said bulging body is set with the girth member that is used to prevent said bulging body opening end cracking.
As a kind of improvement, the bulging body of said opening end is provided with reinforcing strip, and an end of said girth member relies on the end face of said reinforcing strip.
Beneficial effect of the present invention is: compare with existing brake drum; Because the reinforcing strip place of brake drum according to the invention has set up girth member; So reduced the distortion of brake drum, reduced the generation of brake drum opening end cracking phenomena, prolonged the working life of wheel brake drum.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is Fig. 1 left view;
Wherein: 1, rouse body, 2, reinforcing strip, 3, girth member, 4, flange.
Embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the present invention.
Shown in Fig. 1 and Fig. 2 were common, a kind of brake drum comprised tubular drum body 1; One end of said bulging body 1 is provided with adpting flange 4; The other end of said bulging body 1 is an opening end, and the bulging body 1 of said opening end is provided with reinforcing strip 2, and said reinforcing strip 2 is provided with annular groove; The gyration center of said annular groove is consistent with the gyration center of said bulging body 1, is provided with the girth member 3 that is used to prevent said bulging body 1 opening end cracking in the said groove.Reduce the distortion of brake drum, reduced the generation of brake drum opening end cracking phenomena, prolonged the working life of wheel brake drum.
Girth member 3 is a steel ring; After the processing of brake drum foundry goods; Process the groove of placing steel ring at the reinforcing strip place, the steel ring that will process separately again press-fits by interference fit and forms, thereby improves the intensity of brake drum drum body 1 opening end port; Prevent the generation of cracking phenomena, prolong the working life of brake drum.
The present invention is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within protection scope of the present invention.
