Description

Technical Field

[0001] This utility model relates to the field of brake disc technology, and in particular to cast brake discs. Background Technology

[0002] Brake discs are an essential component of vehicles. They reduce vehicle speed by the friction between brake pads and brake discs. In order to obtain sufficient friction, a lot of pressure needs to be applied between the brake pads and brake discs. Therefore, brake discs generate a lot of heat due to friction during operation.

[0003] Traditional brake disc cooling methods typically involve creating cooling grooves on the surface of the brake disc. However, this single cooling method limits the effectiveness of the brake disc and is not conducive to its long-term use. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cast brake disc, including a disc hub and a disc body, the disc body being composed of an upper disc and a lower disc, a plurality of heat dissipation blocks being fixedly connected between the upper disc and the lower disc, heat dissipation channels being provided through the side walls of the heat dissipation blocks, mounting blocks being fixedly connected inside the heat dissipation channels, a plurality of mounting lugs being fixedly connected to the lower surface of the disc hub, steel columns being connected through the side walls of the mounting lugs, and the steel columns being connected to the corresponding mounting blocks.

[0006] As a further description of the above technical solution:

[0007] The hub has multiple first and second heat dissipation strips inside. One side of the first and second heat dissipation strips is fixedly connected to the lower surface of the upper plate, and the other side of the first and second heat dissipation strips is fixedly connected to the upper surface of the lower plate.

[0008] As a further description of the above technical solution:

[0011] An assembly opening is provided through the center of the upper surface of the hub. Multiple mounting holes are provided on the upper surface of the hub outside the assembly opening. A correction hole is provided on the upper surface of the hub between two mounting holes.

[0012] As a further description of the above technical solution:

[0013] The upper surface of the upper plate and the lower surface of the lower plate are provided with a plurality of first heat dissipation grooves and second heat dissipation grooves, which are spaced apart.

[0014] As a further description of the above technical solution:

[0015] The surface of the hub is provided with multiple weight-reducing holes, and a reinforcing strip is fixedly connected to the inner wall of each weight-reducing hole.

[0016] As a further description of the above technical solution:

[0017] The hub is made of aluminum, and the disc body is made of cast iron.

[0018] This utility model has the following beneficial effects:

[0019] 1. Compared with the prior art, this cast brake disc has a hub and disc body connected by a steel column, resulting in a small contact area between them, which avoids heat conduction between them. It is also equipped with multiple heat dissipation blocks, and the side walls of the heat dissipation blocks are provided with heat dissipation channels. The heat dissipation channels facilitate airflow, which is beneficial for the heat dissipation of the brake disc. The multiple first and second heat dissipation strips increase the contact area between the inside of the disc body and the air, which is beneficial for the heat dissipation of the disc body. The multiple first and second heat dissipation grooves increase the contact area between the outside of the disc body and the air, which is beneficial for the heat dissipation of the outside of the disc body.

[0020] 2. Compared with the existing technology, this cast brake disc, through the setting of multiple weight reduction holes, can not only reduce the weight of the disc hub, but also allow air to pass through the disc hub, which is conducive to the heat dissipation of the disc hub. The strength of the weight reduction hole positions can be increased by reinforcing strips. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1 to 5 The cast brake disc provided by this utility model includes a disc hub 1 and a disc body 2. The disc body 2 is composed of an upper disc 21 and a lower disc 22. Multiple heat dissipation blocks 5 are fixedly connected between the upper disc 21 and the lower disc 22. A heat dissipation channel 6 is provided through the side wall of the heat dissipation block 5. An installation block 7 is fixedly connected inside the heat dissipation channel 6. Multiple mounting ears 9 are fixedly connected to the lower surface of the disc hub 1. A steel column 10 is connected through the side wall of the mounting ear 9. The steel column 10 is connected to the corresponding mounting block 7. The setting of the heat dissipation channel 6 facilitates the passage of air through the heat dissipation channel 6, which is beneficial to the heat dissipation of the brake disc.

[0030] The hub 1 has multiple first heat dissipation strips 3 and second heat dissipation strips 4 inside. One side of the first heat dissipation strips 3 and second heat dissipation strips 4 is fixedly connected to the lower surface of the upper plate 21, and the other side of the first heat dissipation strips 3 and second heat dissipation strips 4 is fixedly connected to the upper surface of the lower plate 22. The side wall of the mounting block 7 has a through-hole 8, which is adapted to the steel column 10. The center of the upper surface of the hub 1 has a through-hole 11. Multiple mounting holes 12 are opened on the upper surface of the hub 1 outside the mounting hole 11. A correction hole 13 is opened on the upper surface of the hub 1 between two mounting holes 12, which brings convenience.

[0031] Multiple first heat dissipation grooves 16 and second heat dissipation grooves 17 are provided on the upper surface of the upper plate 21 and the lower surface of the lower plate 22. The multiple first heat dissipation grooves 16 and second heat dissipation grooves 17 are arranged at intervals. Multiple weight reduction holes 14 are provided on the surface of the plate hub 1. A reinforcing strip 15 is fixedly connected to the inner wall of each weight reduction hole 14. The multiple weight reduction holes 14 can not only reduce the weight of the plate hub 1, but also allow air to pass through the plate hub 1, which is conducive to the heat dissipation of the plate hub 1. The reinforcing strip 15 can increase the strength at the position of the weight reduction hole 14. The plate hub 1 is made of aluminum and the plate body 2 is made of cast iron. Both the plate hub 1 and the plate body 2 are cast.

[0032] Working principle:

[0033] The hub 1 and the disc body 2 are connected by a steel column 10. The contact area between the two is small, which avoids heat conduction between them. Multiple heat dissipation blocks 5 are provided. The side wall of the heat dissipation block 5 is provided with heat dissipation channels 6. The heat dissipation channels 6 facilitate air to pass through the heat dissipation channels 6, which is beneficial to the heat dissipation of the brake disc.

[0034] By setting multiple first heat dissipation bars 3 and second heat dissipation bars 4, the contact area between the inside of the disk body 2 and the air is increased, which is beneficial to the heat dissipation inside the disk body 2. By setting multiple first heat dissipation slots 16 and second heat dissipation slots 17, the contact area between the outside of the disk body 2 and the air is increased, which is beneficial to the heat dissipation outside the disk body 2.

[0035] The multiple weight-reducing holes 14 not only reduce the weight of the hub 1, but also allow air to pass through the hub 1, which is beneficial for heat dissipation. The reinforcing strip 15 can increase the strength of the weight-reducing hole 14.
