Abstract
The invention provides a high heat-dissipation brake disc which is used for vehicle disc brake mechanisms. The high heat-dissipation brake disc comprises a disc body and heat-dissipation holes, wherein the middle of the disc body is provided with an axle hole; the heat-dissipation holes are evenly distributed along the periphery of the surface of the disc body; the heat-dissipation holes at one side of the disc body are concave arc-shaped face holes; and the heat-dissipation holes on the other side of the disc body are the cylindrical holes. When the brake disc is braked, a great quantity of air flows in the heat-dissipation holes so as to greatly improve the heat-dissipation efficiency to a large extent.
Description
Affiliated technical field
The present invention relates to a kind of vehicle brake parts, especially, is a kind of brake disc that is used for disc brake mechanism, comprises disk body and radiation hole.
Background technique
In vehicle devices such as automobile, braking mechanism generally adopts disc brake mechanism, it mainly is constructed as follows: fixed brake disc on the rotation shaft of wheel, brake disc edge is provided with hydraulic compressing device, when brake, only need to hold the friction plate in the hold down gag tightly brake disc by hydraulic system, then brake disc slows down under rubbing action fast.Because the huge kinetic energy of automobile needs to dissipate at short notice, and this kind dissipation all is embodied on the frictional heat of brake disc basically, therefore, in brake process, brake disc will generate heat rapidly.Therefore, the heat radiation of brake disc is the problem of necessary consideration in the optimization of vehicle design.For present brake disc, its main heat dissipation design is, on disk body, offer the cylindrical heat radiation through hole that runs through disk body, thereby increase the heat dispersing surface of disk body, yet, in fact in the brake disc rotary course, the pressure on both sides is suitable, therefore, the air flows in the heat radiation through hole is less, and its radiating efficiency can not brought into play efficiently.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of high heat radiation brake disc, this brake disc can make to have a large amount of air flows in the radiation hole in the disc brake braking process, thereby has improved the radiating efficiency of brake disc largely.
The technical solution adopted for the present invention to solve the technical problems is: this height heat radiation brake disc comprises disk body, radiation hole, described disk body central authorities have axis hole, and disc surfaces is along circumferentially even distribution radiation hole, described radiation hole is the arc face of indent in a side of described disk body, is cylindrical hole at the opposite side of described disk body.
As preferably, the degree of depth of described arc face and the deep equality of described cylindrical hole.
As preferably, described arc face is a hemispherical-shaped aperture.
Beneficial effect of the present invention is: this height heat radiation brake disc when rotated, when air-flow skims over the both sides on described radiation hole surface, the distance difference that is experienced, promptly be greater than distance through the cylindrical hole of opposite side through the distance of the arc face of a side, therefore, according to fluid mechanics principle, the air pressure of cylindrical hole side is greater than the air pressure of arc face side, thereby make air-flow fast from the cylindrical hole effluent to arc face side, promptly, cause a large amount of air flows in the radiation hole, thereby improved the radiating efficiency of brake disc largely.

Fig. 2 is the schematic representation of another side of this height heat radiation brake disc.
Fig. 3 is the half sectional view at this height heat radiation brake disc radiation hole place.
Embodiment
The present invention is further described below in conjunction with drawings and Examples:
In Fig. 1-embodiment illustrated in fig. 2, this height heat radiation brake disc comprises disk body 1, radiation hole, described disk body 1 central authorities have axis hole 11, and disk body 1 surface is along circumferentially even distribution radiation hole, described radiation hole is the arc face 12 of indent in a side of described disk body 1, is cylindrical hole 13 at the opposite side of described disk body.
Above-mentioned height heat radiation brake disc, the deep equality of the degree of depth of described arc face 12 and described cylindrical hole 13, and described arc face 12 is a hemispherical-shaped aperture.
Above-mentioned high heat radiation brake disc when rotated, when air-flow skims over the both sides on described radiation hole surface, the distance difference that is experienced, promptly be greater than distance through the cylindrical hole 13 of opposite side through the distance of the arc face 12 of a side, as shown in Figure 3, skim over the curved path that is of arc face 12, shown in curve arrow, and skim over cylindrical hole 13 for straight line path, shown in straight arrows, obviously, the airspeed of skimming over arc face 12 places is greater than the airspeed of skimming over cylindrical hole 13 places, according to fluid mechanics principle, the air pressure of cylindrical hole 13 sides is greater than the air pressure of arc face 12 sides, thus make air-flow fast from cylindrical hole 13 effluents to arc face 12 sides, promptly, cause a large amount of air flows in the radiation hole, thereby improved the radiating efficiency of brake disc largely.
