Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a brake disc structure. Background Art

[0002] During the braking process of the vehicle, the driver presses the brake pedal to push the caliper piston through the brake pipe, and the friction inner and outer plates clamp the brake disc, thereby achieving deceleration and stopping. With the improvement of people's living standards, people's demand for large SUVs and MPVs is getting higher and higher. In addition, the layout of hybrid models by major OEMs now leads to the increasing weight of the whole vehicle. According to the law of conservation of energy, the larger the mass, the more energy is lost in braking and stopping. The increase in the heat capacity and thermal deformation of the brake disc during deceleration will have a certain impact on the stability of braking performance. Most of the existing brake discs on the market are external discs, that is, the outer disc body facing the wheel is connected to the disc cap through a gooseneck, the force is unreasonable, and the ventilation ribs are hidden between the inner and outer discs, and the heat dissipation capacity is poor. Therefore, it is necessary to invent a new brake disc structure to increase the heat capacity of the brake disc, reduce thermal deformation, reduce the thermal decay of the brake system, and improve driving safety.

[0006] Furthermore, the ventilation ribs are arranged in a circular array with the disk cap as the center and are spaced apart between the outer disk body and the inner disk body.

[0007] Furthermore, the ventilation ribs extend from one side of the plate cap close to the gooseneck.

[0008] Furthermore, a slope is provided on one side of the ventilation rib close to the disk cap.

[0019] like Figures 1 to 5 A brake disc structure shown in the figure includes an outer disc body 1, an inner disc body 2, a gooseneck 3, and a disc cap 7. The outer disc body 1 faces the wheel side, and the inner disc body 2 faces the vehicle body side. A plurality of groups of ventilation ribs 4 are evenly and fixedly arranged between the outer disc body 1 and the inner disc body 2. Ventilation grooves 5 are formed between the ventilation ribs 4. The disc cap 7 is connected to the inner disc body 2 through the gooseneck 3. A ventilation ring groove 6 is formed between the inner side edge of the outer disc body 1 and the outer sides of the disc cap 7 and the gooseneck 3. The ventilation ring groove 6 serves as an air inlet facing the wheel side, and the ventilation ring groove 6 is communicated with the ventilation groove 5.

[0020] Preferably, in combination with the above solution, in order to ensure uniform stress and heat distribution, the ventilation ribs 4 are arranged in a ring array with the disk cap 7 as the center and are spaced between the outer disk body 1 and the inner disk body 2.

[0021] Preferably, in combination with the above solution, the ventilation rib 4 is extended to the gooseneck 3 on one side close to the disk cap 7. This structure increases the contact area between the ventilation rib and the air, and the heat dissipation is faster.

[0022] Preferably, in combination with the above solution, a slope is provided on one side of the ventilation rib 4 close to the disk cap 7. This structure plays a role in strengthening support and improving the problems of stress and thermal deformation.

[0023] Preferably, in combination with the above solution, in order to facilitate better ventilation and heat dissipation through airflow exchange, the connection between the gooseneck 3 and the disk cap 7 and the inner disk body 2 is an arc transition.

[0025] Preferably, in combination with the above solution, in order to facilitate positioning during installation, a plurality of positioning screw holes 9 are provided on the wheel mounting surface of the disc cap 7 .

[0026] The utility model changes the brake disc structure of the external disc to connect the disc cap 7 with the inner disc body 2, which can improve the force; a ventilation ring groove 6 is formed between the inner side edge of the outer disc body 1 and the outer side edge of the disc cap 7, and between the outer disc body 1 and the outer side edge of the gooseneck 3. The inlet of the ventilation ring groove 6 faces the wheel side and communicates with the ventilation groove 5, which is more conducive to air flow exchange, ventilation and heat dissipation, and faster heat dissipation. It can effectively improve the heat dissipation efficiency of the brake disc and reduce the influence of thermal decay on braking performance.
