Abstract
The utility model discloses a heat dissipation brake disc, wherein a heat dissipation groove and dust exhaust channels are further formed in a brake disc body to further improve heat dissipation efficiency. The heat dissipation brake disc comprises the brake disc body. A center shaft hole and a round assembling groove are formed in the brake disc body. An internal heat dissipation hole is formed in the round assembling groove. An external heat dissipation hole is further formed in the brake disc body. An arc-shaped groove is formed in the round assembling groove. The dust exhaust channels are further formed in the brake disc body in a radial mode. The arc-shaped groove can accommodate more air and dust generated in a brake friction process so as to enhance the heat dissipation effect. The dust exhaust channels are formed in the radial mode, the dust generated on the heat dissipation brake disc can be further discharged conveniently, therefore, the surface of the heat dissipation brake disc is kept clean, and the heat dissipation brake disc is good in durability.
Description
Technical field
The utility model belongs to the vehicle body fittings technical field, especially relates to a kind of brake disc with great heat radiation effect.
Background technique
Brake disc is important components very in the braking system because the heat radiation that dish is stopped drum stop, under the high speed braking state, be not easy to produce heat fade, its high speed good braking effect is stopped totally so a lot of intermediate car adopts.Brake disc is discoid, and brake disc also rotated when car was advanced, and clamps brake disc by brake caliper and produces braking force, is exactly that the interlock brake caliper is clamped the effect that brake disc plays deceleration or stops when touching on the brake.In brake process, because rubbing action, brake disc will generate heat rapidly and can produce a little powder, can accelerate the ageing process of brake disc, and therefore, the heat radiation of brake disc is the problem of necessary consideration in the optimization of vehicle design.Present heat dissipation plate is many to be distributed with some radiation holes at dish, has heat radiation and dust discharge function concurrently, have certain effect, but radiating efficiency is not high, poor durability.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of brake disc, by increasing heat radiation groove and dust discharge passage at dish, further improve radiating efficiency.
In order to reach above purpose, the utility model provides following technological scheme:
A kind of heat radiation brake disc, comprise the brake disc body, have central shaft hole and circular fitting recess on the described brake disc body, described circular fitting recess is provided with the internal heat dissipating hole, also be provided with outside radiation hole on the brake disc body, be provided with arc groove in the described circular fitting recess, also have radial dust discharge passage on the brake disc body.
As a kind of improvement project of the present utility model, the positive aperture of described outside radiation hole is greater than aperture, the back side.
As a kind of preferred version of the present utility model, described outside radiation hole radially distributes.
As a kind of preferred version of the present utility model, the quantity of described dust discharge passage is 4 to 6.
Compared with prior art, the utlity model has following advantage and beneficial effect:
1. arc groove can hold more air, and can be contained in the dust that produces in the drag friction process, increases radiating effect.The dust discharge passage is radial, is beneficial to the dust that produces on the brake disc and further discharges, and the brake disc surface is kept clean, and serviceability is good.
2. when the positive aperture of outside radiation hole is greater than aperture, the back side, make air-flow flow to the back side of small aperture fast from wide-aperture front, accelerate speed air flow, good heat dissipation effect.
3. produce centrifugal force during owing to the brake disc rotation, therefore the radiation hole that radially distributes and the air-flow direction of disc surfaces are consistent, and are beneficial to hot air and discharge.
4. the utility model is reasonable in design, and heat radiation and dust discharge are effective, thereby can improve the serviceability of brake disc, is easy to be extended and applied.
Description of drawings
The structural representation of the heat radiation brake disc that Fig. 1 provides for embodiment one.
The structural representation of the heat radiation brake disc that Fig. 2 provides for embodiment two.
Reference numerals list:
1-brake disc body, 2-central shaft hole, the circular fitting recess of 3-, 4-internal heat dissipating hole, the outside radiation hole of 5-, 6-arc groove, 7-dust discharge passage.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand following embodiment and only be used for explanation the utility model and be not used in restriction scope of the present utility model.Need to prove, word " preceding ", " back ", " left side ", " right side ", the "up" and "down" used are described below refer to the direction in the accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of specific features geometrical center.
Embodiment one:
Heat radiation brake disc as shown in Figure 1, comprise brake disc body 1, have central shaft hole 2 and circular fitting recess 3 on the described brake disc body 1, described circular fitting recess 3 is provided with internal heat dissipating hole 4, also be provided with outside radiation hole 5 on the brake disc body 1, be provided with arc groove 6 in the described circular fitting recess, also have radial dust discharge passage 7 on the brake disc body.Internal heat dissipating hole 4 is preferred rounded evenly distributed, good heat dissipation effect.Arc groove 6 can hold more air, and can be contained in the dust that produces in the drag friction process, increases radiating effect.Dust discharge passage 7 is radial, is beneficial to the dust that produces on the brake disc and further discharges, and the brake disc surface is kept clean, and serviceability is good.Provided a kind of example of shape of dust discharge passage among Fig. 1, i.e. straight line type, the dust discharge passage also can be designed to camber line shape, adapts to air and the dust flow direction on brake disc surface more.Arc groove 6 is preferably 4 among the figure, is issued to best radiating effect in the situation that does not influence brake disc normal braking effect.
As a kind of preferred version of the present utility model, described outside radiation hole 5 radially distributes.Because produce centrifugal force during the brake disc rotation, therefore the radiation hole that radially distributes and the air-flow direction of disc surfaces are consistent, are beneficial to hot air and discharge.
As a kind of preferred version of the present utility model, the quantity of described dust discharge passage 7 is 4 to 6, and quantity too much can cause the brake disc rigidity to descend for good, distortion when stressed easily, and quantity is crossed the dust discharge effect that does not reach at least.
Embodiment two:
We are the front with the brake disc surface of seeing among Fig. 1, are the front with the face opposite with it, and as embodiment one improvement project, as shown in Figure 2, described outside radiation hole 5 positive apertures are greater than aperture, the back side, and namely outside radiation hole is truncated cone.Outside radiation hole 5 positive apertures make air-flow flow to the back side of small aperture fast from wide-aperture front during greater than aperture, the back side, accelerate speed air flow, good heat dissipation effect.All the other technical characteristicss are identical with embodiment one in this example.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned mode of execution, also comprises the technological scheme of being made up of above technical characteristics combination in any.
