Abstract
The utility model relates to an automobile brake drum with annular grooves and belongs to the technical field of automobile parts. The automobile brake drum comprises a brake drum body; and the external circumference of the opening end of the brake drum body is provided with at least one annular groove which is perpendicular to the axis of the brake drum body. The cross section of each annular groove is circular arc, rectangular or trapezoid. The annular grooves and the brake drum body are integrated. The intensity and the rigidity of the brake drum are improved, and the possibility of the cracking and deformation the brake drum, which are caused under the action of heat and braking force, can be reduced, the temperature of the brake drum can be reduced effectively, the heat influence to a steel ring and a tire can be reduced, the service life of the brake drum, a friction plate and the tire is prolonged, the accidents which are caused by the cracking of the brake drum and the blowout of the tire can effectively prevented, and the running safety can be improved.
Description
Technical field
The utility model relates to automobile brake drum, is specifically related to a kind of automobile brake drum with circular groove, and it belongs to technical field of automobile parts.
Background technique
At present, the similar peviform of automobile brake drum drum shape, an end is the brake drum drum end; The other end is opening-like, and automobile brake drum is that pure foundry goods processes usually, in vehicle actual travel process; The frequency of utilization of brake drum is high, because under the effect of heat and braking force, one end easy of crack or the be full of cracks of brake drum drum body opening shape; Cause reduce the working life of automobile brake drum, thereby can influence vehicle driving; Certainly,,, generally all can not accept because of its material therefor makes that drum body cost is high though can avoid drum body opening shape one end can not to ftracture or chap through adopting alloy materials such as steel to make automobile brake drum; The mode of wall thickness that in addition can be through increasing brake drum drum body is improved the problem that bulging body exists, though can play certain anticracking effect, the brake drum overall dimensions can strengthen, and influence is installed and used.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology, and a kind of automobile brake drum with circular groove is provided, and it is simple in structure, realizes lightweight, not only has better radiating effect, and guarantees that braking ability is good, improves the traffic safety performance.
The technological scheme that the utility model solves the problems of the technologies described above is following:
A kind of automobile brake drum with circular groove comprises brake drum drum body, is characterized in, on the excircle of said brake drum drum body opening end, be provided with at least 1 with the vertical circular groove of the bulging body axis of said brake drum.
Further, described circular groove transverse section is circular arc, rectangle or trapezoidal.
Further, said circular groove and said brake drum drum body are structure as a whole, and the quantity of said circular groove is 2.
The beneficial effect of the utility model is: owing to be provided with circular groove at automobile brake drum drum body opening end external peripheral surface, reduced because heat and braking force effect make the probability of brake drum cracking, distortion, kept brake drum and the good applying of brake shoe.Also increased simultaneously the heat diffusion area of brake drum; Thereby can effectively lower the brake drum temperature; Reduced heat effects to steel ring and tire; Improved the working life of brake drum, friction plate and tire, effectively prevented the accident that causes owing to brake drum be full of cracks, tyre explosion to have improved traveling security.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the transverse section sectional view of three kinds of shapes of the utility model circular groove.
Among Fig. 1～Fig. 2,1, brake drum drum body; 2, circular groove.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1; A kind of automobile brake drum with circular groove comprises brake drum drum body 1, is characterized in; On the excircle of said brake drum drum body 1 opening end, be provided with 2 circular grooves 2 with said brake drum drum body 1 axis normal, said circular groove 2 is cast into integrative-structure with said brake drum drum body 1.
As shown in Figure 2, be three kinds of shapes of circular groove 2 transverse section, these three kinds of shapes are respectively circular arc, rectangle or trapezoidal.
Only represent three kinds of shapes commonly used among Fig. 2, be not limited to the utility model, all within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
