The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model embodiment provides a shaft-mounted brake disc, such as Figure 1-4 As shown, it includes a disk body 1 and a mounting disk 2, the disk body 1 and the mounting disk 2 are connected by a connecting block 3 and a fixing bolt 4, the connecting block 3 is fixed to the side of the mounting disk 2, four groups of connecting blocks 3 are arranged and distributed in a circumferential array, the surface of the disk body 1 is provided with a connecting slot that matches the shape of the connecting block 3, the mounting disk 2 and the disk body 1 are rotatably clamped, two groups of fixing bolts 4 are arranged, and the two groups of fixing bolts 4 are symmetrically distributed in the disk body 1, the surface of the disk body 1 is provided with a threaded groove that matches the fixing bolt 4, the surface of the mounting disk 2 is provided with a screw hole that matches the fixing bolt 4, the fixing bolt 4 passes through the mounting disk 2 and is connected to the disk body 1, and the connecting block 3 and the fixing bolt 4 are arranged. The disc body 1 and the mounting disc 2 are connected by a rotating and clamping connecting block 3, and four groups of connecting blocks 3 are inserted into the connecting slots on the surface of the disc body 1 to achieve a tight connection between the disc body 1 and the mounting disc 2. After the connection between the disc body 1 and the mounting disc 2 is completed, two groups of fixing bolts 4 are inserted into the mounting disc 2 and connected to the disc body 1 in a threaded connection manner. The fixing bolts 4 limit the rotation of the mounting disc 2 and the disc body 1. The device connects the disc body 1 and the mounting disc 2 only by two groups of fixing bolts 4, simplifies the connecting parts between the two without affecting the stability of the connection, makes the disassembly and assembly between the disc body 1 and the mounting disc 2 more convenient, and also reduces its processing cost.

[0021] The surface of the mounting plate 2 is provided with strip heat dissipation grooves 5, and eight groups of the strip heat dissipation grooves 5 are arranged and distributed in an array around the center of the mounting plate 2. By providing the strip heat dissipation grooves 5, the strip heat dissipation grooves 5 increase the contact surface between the mounting plate 2 and the air, thereby accelerating its heat dissipation and achieving the purpose of rapid cooling.

[0022] The heat dissipation slot 5 is a transparent type, and the inner wall of the heat dissipation slot 5 is set as an inclined surface. A ventilation hole 6 is opened on the surface of the disk body 1 corresponding to the position where the heat dissipation slot 5 is located. By setting the inner wall of the heat dissipation slot 5 as an inclined surface, when the vehicle body is driving, the heat dissipation slot 5 set on the inclined surface guides the airflow to enter the mounting disk 2 and blow out from the ventilation hole 6 of the disk body 1, thereby further increasing the contact surface of the air, thereby further improving the heat dissipation effect of the mounting disk 2 and the disk body 1.

[0024] The upper surface of the connection block 3 is set as an inclined surface, and the upper surface of the connection slot of the disk body 1 is set as an inclined groove. By setting the upper surface of the connection block 3 as an inclined surface, its connection tension can be increased to avoid looseness between the disk body 1 and the mounting disk 2.

[0025] The inner wall of the screw head of the fixing bolt 4 is provided with a tooth-shaped convex surface which is opposite to the loosening direction thereof. The tooth-shaped convex surface provided on the inner wall of the fixing bolt 4 can play a role in preventing loosening.
