Description

The brake disc

Technical field

The utility model is relevant for a kind of brake disc, and the design of especially a kind of tool groove and perforation can increase the brake 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 a 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 notion of disc brakes that Here it is.

As shown in Figure 1, by the both side surface of generally commonly using brake disc 1 is smooth flat, and when the user steps on brake, the lining of this brake just immediately the action clamp this commonly use the brake disc 1, commonly use under brake 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 brake disc 1 is a smooth flat, so the powder that this lining ground can't be given 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 brake disc 1, this brake disc 1 has a rounded spider 11, from the outward extending friction of these spider 11 peripheries portion 12, and plural number is formed at a lip-deep friction indentation 13 of this friction portion 12.The effect of brake is relevant with frictional force, if the big braking effect of frictional force is good naturally.Frictional force is very big with the relation of the material between rubbing surface again, and is also relevant with the thermal efficiency, when the good surface of contact of material contacts with each other, can produce very big frictional force, and the heat that produces because of friction also can increase the temperature rising.

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

Yet, known brake disc 1 still has some shortcomings in the use, be attached to mud, dust and water on the friction part 12 that does not have friction indentation 13, can't be by discharging in the raceway groove that produced of brake indentation 13, and then influence braking effect, and the friction power difference that the friction portion on simultaneously opposite both sides 12 is suffered, the uneven result of abrasion more makes the reduction in working life of this brake 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.

Wherein, this two rubbing surface is provided with the shape long groove of symmetry each other.

This two rubbing surface is provided with the asymmetric each other long groove of shape.

Each long groove with the center of circle as being equally spaced.

This long groove forms with the same depth extension.

This long groove forms with the different depth extension.

This perforation number is more than or equal to 3.

The aperture of those perforation is at 1mm; 1.5mm; 2.0mm; 2.5mm; 3.0mm between arbitrary aperture.

Be formed with some radiation holes on this two rubbing surface.

The beneficial effects of the utility model are: for the brake disc of the present utility model that achieves the above object is provided with a center axial region and is located at the friction portion of this axial region periphery, center, this center axial region is in order to be fitted to each other mutually with wheel shaft, the opposite sides of this friction portion respectively forms a rubbing surface, then is provided with long groove at least one rubbing surface; Wherein, be provided with plurality of through holes in this long groove, the design of this long groove can increase the stress of brake weight with brake disc itself effectively, this brake disc can not produce side direction or stress distortion longitudinally because of excessive frictional force yet, also can effectively get rid of attached to mud, dust and water on this brake disc, to increase the effect of frictional force and heat radiation simultaneously by each perforation.
