Description

The radiating structure of braking disc

Technical field

The utility model is relevant for a kind of radiating structure of braking disc, and especially a kind of design of tool radiation hole can increase the braking disc of the effect of frictional force and heat radiation.

Background technique

The brake system of automobile generally can be divided into disc brakes, drum brakes, and is used in the pneumatic brake on the large-scale means of transportation.Wherein, disc brakes is the principle of utilizing oil pressure, with the brake pumping brake oil is thrown in the brake oil pipe, utilize connecting pipe principle to produce powerful pressure, lining is inwardly strutted the contact disc, to produce the strength of brake, the simplest concept of disc brakes that Here it is.

As shown in Figure 1, be smooth flat by the both side surface of generally commonly using braking disc 1, in order to do step on when brake as the user, the lining of this brake just immediately action is clamped this and is commonly used braking disc 1, commonly use under braking disc 1 friction at a high speed through this because of this lining, must grind many powder, but this both side surface of commonly using braking disc 1 is smooth flat, therefore the powder that this lining can't be ground gives off smoothly, and the friction between each smooth flat and lining is also limited.

Moreover as shown in Figure 2, for other plants commercially available common braking disc 1, this braking disc 1 has a rounded spider 11, from the outward extending friction of these spider 11 peripheries section 12, and plural number is formed at a lip-deep friction indentation 13 of this friction section 12.The effect of brake is relevant with frictional force, if the large braking effect of frictional force is naturally good.Frictional force is very large with the relation of the material between the rubbing surface again, and is also relevant with radiating efficiency, when the good surface of contact of material contacts with each other, can produce very large frictional force, and the heat that produces because of friction also can increase the temperature rising.

Consult shown in Figure 3ly, for the braking disc 1 of Fig. 2 is installed in aspect on the brake 2, this brake 2 has the brake callipers 22 that a brake oil pipe 21, connects this brake oil pipe, and two linings 23 that can closely seize respectively this braking disc 1 on both sides by the arms.In the brake oil on the vehicle is thrown brake oil pipe 21 into, can flow into this brake callipers 22 along this brake oil pipe 21.At this moment, this brake callipers 22 accumulate pressure and push this two lining 23 against and clamp this braking disc 1, very end vehicle to produce brake control power.Wherein, the design of this friction indentation 13 can increase brake weight effectively with the stress of braking disc 1 itself, adaptation is better when allowing lining 23 with this braking disc 1 friction, and this braking disc 1 can not produce side direction or longitudinally stress distortion because of excessive frictional force yet.

Yet, known braking disc 1 still has some shortcomings in the use, be attached to without mud, dust and water on the friction part 12 of friction indentation 13, can't be by discharging in the raceway groove that produces of brake indentation 13, and then affect braking effect, and the suffered friction power of the friction section on simultaneously opposite both sides 12 is different, and the uneven result of abrasion more makes reduce the working life of this braking disc 1, even can cause the phenomenon that the steering wheel generation is shaken when braking, and the driver is exposed under the dangerous state.
