Abstract
The utility model discloses brake drum before a kind of commercial car, comprise hollow cylindrical drum body, described bulging body is along the circumferential direction braking surface, one end of described bulging body arranges the attachment face with Flange joint, the other end is opening, the braking surface of described opening offers installation step, and the braking surface arranged outside girth member of described opening, the braking surface below described girth member arranges oblique rib.The utility model is by arranging oblique rib, increase the area of contact of braking surface and air, improve radiating effect, by arranging installation step, making easy for installation, by installing girth member on braking surface, reducing the distortion of brake drum, reduce the generation of the opening cracking phenomena of brake drum, extend the working life of brake drum.
Description
Technical field
The utility model belongs to field of automobile, is specifically related to brake drum before a kind of commercial car.
Background technique
Front brake drum is the important component part of drum brakes system, and when braking, piston applies pressure to two brake blocks, makes it to be close to tympanum inwall, by between the frictional force that produces stop the rotation of wheel, reach the object of braking.Before commercial car, brake drum is than brake drum before all the other dillies, intensity and heat dispersion there is higher requirement, before car of the prior art, brake drum adopts hollow cylindrical to design mostly, the defect of this kind of structure is: heat dissipation potential is poor, comparatively large to the heat effects of steel ring and tire, there will be the brake drum be full of cracks produced because heat is high, or even the accident such as tyre explosion, intensity is also comparatively general in addition, have impact on the Security of driving.
Model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of good heat dissipation effect, brake drum before the commercial car that intensity is high.
Brake drum before a kind of commercial car, hollow cylindrical drum body, described bulging body is along the circumferential direction braking surface, one end of described bulging body arranges the attachment face with Flange joint, the other end is opening, the braking surface of described opening offers installation step, and the braking surface arranged outside girth member of described opening, the braking surface below described girth member arranges oblique rib.
Further, described oblique rib is evenly distributed on braking surface, and the tip height of described oblique rib is lower than the axial top of braking surface, and the rib thickness towards attachment face reduces gradually.
Further, the thickness of described installation step is all lower than a dot thickness of oblique rib.
The beneficial effects of the utility model: brake drum before a kind of commercial car that the utility model provides, by arranging oblique rib, increase the area of contact of braking surface and air, improving radiating effect, by arranging installation step, making easy for installation, by installing girth member on braking surface, reduce the distortion of brake drum, reduce the generation of the opening cracking phenomena of brake drum, extend the working life of brake drum
Accompanying drawing explanation
Brake drum structure schematic diagram before a kind of commercial car that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples only for illustration of the utility model but not for limiting scope of the present utility model.
See Fig. 1, it is brake drum structure schematic diagram before a kind of commercial car that the utility model provides.
As shown in Figure 1, brake drum before a kind of commercial car, comprise hollow cylindrical drum body 1, described bulging body 1 is along the circumferential direction braking surface 2, one end of described bulging body 1 arranges the attachment face 3 with Flange joint, and the other end is opening, and the braking surface 2 of described opening offers installation step 5, the braking surface 2 arranged outside girth member 6 of described opening, the braking surface below described girth member 6 arranges oblique rib 4.
In the utility model embodiment, by installing girth member on braking surface, reducing the distortion of brake drum, reducing the generation of the opening cracking phenomena of brake drum, extend the working life of brake drum.
Described oblique rib 4 is evenly distributed on braking surface 2, and the tip height of described oblique rib 4 is lower than the axial top of braking surface 2, and the rib thickness towards attachment face 3 reduces gradually.
The thickness of the step of described installation step 5 is all lower than a dot thickness of oblique rib.
Brake drum before a kind of commercial car that the utility model provides, comprise hollow cylindrical radiation brake drum drum body 1, radiation brake drum drum body 1 comprises the attachment face 3 of braking surface 2 along the circumferential direction and end, at braking surface 2 along short transverse being uniformly distributed oblique rib 4, the tip height of oblique rib 4 is lower than the axial top of braking surface 2, rib thickness towards attachment face 3 reduces gradually, object is the heat diffusion area increasing brake drum, air is caused to flow, produce certain air cooling effect, the utility model is made to have certain automatic cooling function, also can not have influence on assembling of the present utility model simultaneously.
The utility model offers installation step 5 on the braking surface 2 of drum body opening, and in installation step 5, the thickness of all steps is all lower than a dot thickness of oblique rib 4.The setting of installation step 5 improves comfort level during assembling, because the thickness of steps all in installation step 5 plays dot thickness, so can not affect the radiating effect brought by oblique rib 4 all lower than oblique rib 4.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
