Description

Technical Field

[0001] The invention relates to the technical field of brake discs, in particular to a high thermal conductivity vermicular ink brake disc. Background Art

[0002] High thermal conductivity vermicular graphite brake disc is a new type of brake disc. Its main feature is that it uses high thermal conductivity vermicular graphite material (usually creep cast iron). This material not only has high thermal conductivity, but also has excellent friction performance and wear resistance. The brake disc is an important part of the vehicle braking system.

[0003] In the prior art, a Chinese patent application with publication number CN110966326A discloses a fast cooling brake disc, which utilizes the brake disc to rotate with the shaft sleeve, and through the vortex principle, natural wind is sucked in from the cyclone inlet, and then enters the cyclone cavity, and enters the honeycomb patch through the cyclone channel. The honeycomb patch effectively conducts and dissipates heat, and takes away the heat through the air outlet on the air outlet cover, thereby realizing the cooling of the brake disc under normal use, without other power, natural heat dissipation, good heat dissipation effect, low operating cost, and solving the problem of poor cooling effect of the existing brake disc.

[0004] The existing brake discs are divided into single-sided brake discs and double-sided brake discs. When the double-sided brake disc is working, both sides of the double-sided brake disc will contact the brake pads at the same time, thereby realizing the function of braking the car. After the double-sided brake disc works for a long time, the disc surface of the double-sided brake disc will be greatly worn due to the long-term contact with the brake pads.

There are multiple air ducts 30 and heat dissipating fins 33, and they are all arranged in an annular manner. The exhaust head 31 on the air duct 30 and the heat dissipating fins 33 are in the same direction, wherein one end of the air duct 30 away from the annular tube 19 extends to between the front brake disc 102 and the rear brake disc 103, and the exhaust head 31 is positioned between the front brake disc 102 and the rear brake disc 103, to ensure that the gas discharged from the exhaust head 31 can be blown toward the heat dissipating fins 33.

[0029] Working principle: When in use, the motor 6 drives the worm 8 on the driving shaft 7 to rotate, and the worm 8 cooperates with the worm gear 10 on the rotating ring 9, and the rotating ring 9 drives the helical gear ring 11 to rotate, and then the helical gear ring 11 cooperates with the helical gear 13 on the auxiliary shaft 12, and the auxiliary shaft 12 rotates the spare brake disc 2 180 degrees, so that the back of the spare brake disc 2 is on the front of the brake disc body 1, and the back of the spare brake disc 2 is in contact with the brake pad, so as to achieve the effect of automobile braking; The gas is introduced into the shunt pipe 18 through the air outlet pipe 17 by the air pump 16, and the gas in the shunt pipe 18 is introduced into the annular pipe 19. The gas in the annular pipe 19 is divided into three parts, and one part of the gas enters the extrusion airbag 25 through the exhaust pipe 20. The extrusion airbag 25 expands due to the filling of gas, and the circular block 23 is pushed to slide in the installation cavity 22 by the extrusion airbag 25. The positioning rod 24 on the circular block 23 is inserted into the positioning groove 26 of the spare brake disc 2 to ensure that the spare brake disc 2 will not change position in the replacement groove 3 after the front and back sides are replaced; The heat on the brake disc body 1 can be absorbed by the heat-conducting ring 32, and the absorbed heat will be quickly dissipated through the heat dissipation fins 33. At the same time, one portion of the gas in the annular tube 19 enters the air duct 30, and the gas in the air duct 30 is discharged through the exhaust head 31. The exhausted gas will blow to the position of the heat dissipation fins 33, and the last portion of the gas in the annular tube 19 is passed into the shaping airbag 35 through the connecting tube 36. The deformation pressure on the brake disc body 1 is shared by the expansion of the shaping airbag 35, thereby effectively reducing the deformation degree of the brake disc body 1.

[0030] In the present invention, the extruded airbag 25 and the shaped airbag 35 are both made of high-temperature materials, and the heat dissipation of the brake disc body 1 is accelerated by using the heat dissipation fins 33, so that the service life of the extruded airbag 25 and the shaped airbag 35 can be improved. The contact surface between the brake pad and the brake disc body 1 in the automobile is above the bevel gear 13, ensuring that the bevel gear 13 will not affect the rotation of the brake disc body 1, and the contact between the brake disc body 1 and the brake pad. The spare brake disc 2 will not contact the brake pad when the angle is rotated.

[0031] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
