Quick heat dissipation motor vehicle brake disc

Technical Field

The utility model relates to a brake disc field specifically is a motor vehicle brake disc fast dispels heat.

Background

In the braking system of the automobile, the disc braking system is more sensitive in braking, has better heat dissipation effect than a drum brake, does not need to adjust the braking clearance and is easy to maintain. At present, in order to improve the heat dissipation performance of the brake disc, an air duct is usually formed in the outer wall of the brake disc, heat dissipation holes communicated with the air duct are formed in the disc surface of the brake disc, and the heat dissipation performance of the brake disc is improved through rapid circulation of air in the air duct. However, with the long-term use of the brake disc, the phenomenon of thermal attenuation of the brake disc still exists, so that the research on the heat dissipation performance of the brake disc is still an important subject at present.

SUMMERY OF THE UTILITY MODEL

For solving prior art's not enough, the utility model provides a motor vehicle brake disc fast dispels heat, it can further improve the heat-sinking capability of brake disc, slows down the thermal attenuation effect of brake disc, improves the brake performance and the life of brake disc.

The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:

the utility model provides a motor vehicle brake disc fast dispels heat, includes the brake disc body, this external circle department of brake disc sets up annular wind channel, the wind channel is outer narrow wide "wine bottle form" in along the cross-section of brake disc body diameter, the wind channel both sides set up first heat dissipation strip and second heat dissipation strip respectively, first heat dissipation strip is the even setting in wind channel both sides of circumference with the second heat dissipation strip respectively, brake disc body both sides all set up a plurality of louvres that are linked together with the wind channel, the wind channel bottom is the circumference and sets up a plurality of ventilation holes.

The radiating holes are formed between the adjacent first radiating strips/second radiating strips.

The radiating holes are regularly and alternately arranged on two sides of the brake disc body.

The first heat dissipation strips and the second heat dissipation strips are arranged in a staggered mode.

The first radiating strip and the second radiating strip are arranged at a certain angle with the radius of the brake disc body.

Contrast prior art, the beneficial effects of the utility model are that:

the utility model discloses set the wind channel to outer narrow interior wide shape, when the brake disc used, the cavity of inside broad can collect the heat better, and outside narrower passageway air flow rate is faster, can promote thermal quick outflow, plays better radiating effect. The first radiating strips and the second radiating strips are further arranged on the two sides of the air duct of the device, and the radiating areas of the brake disc body in the air duct can be increased through the radiating strips on the two sides, so that a better radiating effect is achieved.

The first heat dissipation strips and the second heat dissipation strips which are arranged in a staggered mode can guarantee the air flow circulation space of the air duct on the premise that the heat dissipation area is not lost, and the heat dissipation effect of the air duct is better.

The ventilation hole of wind channel bottom can improve the circulation effect of air in the wind channel equally, makes the heat circulate in a plurality of directions, plays better radiating effect.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

As shown in fig. 1-3, a motor vehicle brake disc fast dispels heat, including brake disc body 1, annular wind channel 2 is processed out to 1 excircle department of brake disc body, and the brake disc body rotates along with the wheel, therefore the wind channel is carrying out the air current exchange with the air incessantly, can be quick distribute away the braking heat with the brake disc. The section of wind channel 2 along 1 diameter of brake disc body is "wine bottle form" of outer narrow internal width, and the width of wind channel excircle is less than the width of interior circle promptly, can make the cavity of inside broad collect the heat better through this kind of design, and outside narrower passageway air flow rate is faster, promotes thermal quick outflow. 2 both sides in wind channel are first heat dissipation strip 3 of integrated into one piece and second heat dissipation strip 4 respectively, first heat dissipation strip 3 is the circumference respectively with second heat dissipation strip 4 and evenly sets up in 2 both sides in wind channel, first heat dissipation strip has increased the heat radiating area of brake disc body in the wind channel with the second heat dissipation strip, can play better radiating effect. A plurality of heat dissipation holes 5 communicated with the air duct 2 are formed in the two sides of the brake disc body 1, communication between the brake pad body and the air duct is increased through the heat dissipation holes, convergence and dispersion of hot air flow are accelerated, and heat dissipation capacity of the brake pad is improved. The bottom of the air duct 2 is circumferentially provided with a plurality of vent holes 6. The ventilation hole communicates the outside with the air duct in the other direction, so that the heat dissipation is accelerated.

Specifically, the heat dissipation holes 5 are formed between the adjacent first heat dissipation strips 3/second heat dissipation strips 4. The first radiating strip 3 and the second radiating strip 4 can not be damaged in the position of seting up of louvre, guarantees the intensity of brake disc body.

Specifically, the heat dissipation holes 5 are regularly and alternately arranged on two sides of the brake disc body 1. The staggered arrangement of the heat dissipation holes can increase the space between two adjacent heat dissipation holes, thereby ensuring the strength of the brake disc body.

Specifically, the first heat dissipation strips 3 and the second heat dissipation strips 4 are arranged in a staggered manner. The first heat dissipation strips and the second heat dissipation strips which are arranged in a staggered mode can guarantee the air flow circulation space of the air duct on the premise that the heat dissipation area is not lost, and the heat dissipation effect of the air duct is better.

Specifically, the first heat dissipation strip 3 and the second heat dissipation strip 4 are arranged at a certain angle, preferably 15 degrees, with the radius of the brake disc body 1. The radiating strip with the angle can have better airflow disturbance effect, thereby accelerating the heat exchange and playing a better cooling effect.
