Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and in particular relates to an automobile brake disc and an automobile. Background Art

[0002] With the development of the automobile industry, people's requirements for automobile braking performance (distance) are getting higher and higher, and the thermal performance of the brake disc is an important factor affecting the stability of automobile braking performance. The ventilated brake disc includes two concentric annular discs, which are connected by reinforcing ribs. The reinforcing ribs and the annular discs on both sides define the path of the brake disc ventilation duct. The cooling air flows through the ventilation duct between the annular discs on both sides and takes away the heat generated by friction braking, thereby reducing the temperature of the brake disc and avoiding overheating of the brake disc and causing a decrease in braking performance. In order to ensure stable braking performance of the brake, it is key to optimize the ventilation duct structure and achieve efficient heat transfer. Traditional ventilated brake discs generally use strip reinforcement ribs, which are evenly distributed between the annular discs on both sides in the circumferential direction (such as Figure 6 As shown in the figure, the contact and heat dissipation area between the strip reinforcement ribs and the air is small, and it is not easy for air to enter between the annular discs on both sides, resulting in less air intake. As a result, the heat generated by emergency braking during high-speed rotation of the brake disc is not easily dissipated. The brake disc takes a long time to dissipate heat and cool down, and the temperature will rise sharply. The disc surface is prone to absorbing heat energy and turning red, thereby reducing the service life of the brake disc and friction pad. Summary of the Invention

[0003] The utility model aims to provide an automobile brake disc and an automobile, so as to overcome the defect of poor heat dissipation effect of automobile brake discs in the prior art.

[0004] The utility model is realized by adopting the following technical scheme: an automobile brake disc, comprising an annular disc on two sides, a plurality of reinforcing ribs are arranged between the annular discs on both sides, the reinforcing ribs between the annular discs on both sides are arranged obliquely in a clockwise direction or in a counterclockwise direction, and the width of the outer opening between two adjacent reinforcing ribs is greater than the width of the inner opening.

[0005] Furthermore, the reinforcing rib is S-shaped.

[0006] Furthermore, the reinforcing ribs are divided into long reinforcing ribs and short reinforcing ribs, and the long reinforcing ribs and short reinforcing ribs are arranged alternately along the circumferential direction. The long reinforcing ribs and short reinforcing ribs both include an outer section, a middle section and an inner section connected in sequence, and the outer end of the outer section of the long reinforcing rib is outside the outer end of the outer section of the short reinforcing rib.

[0007] Furthermore, the length of the outer section of the long reinforcing rib is greater than the length of the outer section of the short reinforcing rib.

[0008] A car comprises the above-mentioned car brake disc.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The utility model arranges the reinforcing ribs between the annular disks on both sides to be tilted in the clockwise direction or the counterclockwise direction. When in use, the reinforcing ribs between the annular disks on both sides of the left wheel can be tilted in the counterclockwise direction, while the reinforcing ribs between the annular disks on both sides of the right wheel can be tilted in the clockwise direction. In this way, the air inlet between two adjacent reinforcing ribs can be oriented towards the direction of wheel rotation, which is more conducive to wind entering the air inlet between the two adjacent reinforcing ribs.

[0011] The utility model can greatly increase the heat dissipation area of ​​the reinforcement rib by designing the reinforcement rib into an S-shaped structure including an outer section, a middle section and an inner section, thereby improving the heat dissipation performance of the brake disc.

[0019] In order to help those skilled in the art better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0020] A vehicle brake disc comprises two annular discs 1, with a plurality of reinforcing ribs 2 arranged between the annular discs 1 on both sides. The reinforcing ribs 2 between the annular discs 1 on both sides are arranged obliquely in the clockwise direction or in the counterclockwise direction.

[0021] In the present invention, the reinforcing ribs 2 between the annular disks 1 on both sides can be arranged in a clockwise or counterclockwise direction. Figure 4 As shown, the reinforcing ribs 2 between the annular disks 1 on both sides are arranged in a clockwise tilted manner, as shown in FIG. Figure 5 As shown, the reinforcing ribs 2 between the annular discs 1 on both sides are arranged obliquely in the counterclockwise direction. When in use, the reinforcing ribs 2 on the brake disc installed on the left wheel are arranged obliquely in the counterclockwise direction, and the reinforcing ribs 2 on the brake disc installed on the right wheel are arranged obliquely in the clockwise direction. In this way, the air inlet between the two adjacent reinforcing ribs 2 can face the direction of wheel rotation, which is more conducive to the wind entering the air inlet between the two adjacent reinforcing ribs 2, thereby improving the heat dissipation performance of the brake disc. The annular discs 1 on both sides are concentrically arranged and are both annular.

[0022] The width of the outer opening 3 between two adjacent reinforcing ribs 2 is greater than the width of the inner opening 4 .

[0023] In the present invention, the width of the outer opening 3 between two adjacent reinforcing ribs 2 is greater than the width of the inner opening 4. The outer opening 3 between two adjacent reinforcing ribs 2 is the air inlet, and the inner opening 4 between two adjacent reinforcing ribs 2 is the air outlet. The width of the air inlet is greater than the width of the air outlet. By making the width of the air inlet greater than the width of the air outlet, it is more conducive to wind entering the air inlet during the rotation of the brake disc.

[0024] The reinforcing rib 2 is S-shaped.

[0025] The present invention can effectively increase the heat dissipation area of ​​the reinforcing rib 2 by designing the reinforcing rib 2 into an S-shaped structure, thereby improving the heat dissipation performance of the brake disc.

[0026] The reinforcing ribs 2 are divided into long reinforcing ribs 8 and short reinforcing ribs 9. The long reinforcing ribs 8 and the short reinforcing ribs 9 both include an outer section 5, a middle section 6 and an inner section 7 connected in sequence. The outer end of the outer section 5 of the long reinforcing rib 8 is outside the outer end of the outer section 5 of the short reinforcing rib 9. The long reinforcing ribs 8 and the short reinforcing ribs 9 are staggered in the circumferential direction.

[0027] The utility model arranges the long reinforcing ribs 8 and the short reinforcing ribs 9 in a staggered manner along the circumferential direction, and the outer ends of the outer sections 5 of the long reinforcing ribs 8 are outside the outer ends of the outer sections 5 of the short reinforcing ribs 9. During the rotation of the brake disc, the staggered structure of the outermost ends of the long reinforcing ribs 8 and the outermost ends of the short reinforcing ribs 9 in the circumferential direction makes it easier for wind to enter the air inlet between the annular discs 1 on both sides.

[0028] The length of the outer section 5 of the long reinforcing rib 8 is greater than the length of the outer section 5 of the short reinforcing rib 9 .

[0029] A car comprises the above-mentioned car brake disc.
