[0001] The utility model relates to the technical field of motorcycle brakes, in particular to a brake disc which is easy to assemble. Background Art

[0002] The brake disc, in simple terms, is a round disc that rotates when the car is moving. The brake caliper clamps the brake disc body to generate braking force. When the brake is applied, it clamps the brake disc to slow down or stop the car. The brake disc has a good braking effect and is easier to maintain than drum brakes. Most of the existing motorcycle brake discs are composed of an inner fixed disc and an outer brake disc. The brake disc with the publication number "CN210484463U" includes a fixed disc body and a brake disc body that are separately arranged. The fixed disc body and the brake disc body are detachably connected through a connecting assembly. The brake disc body includes an inner annular surface, an inner The annular surface is evenly distributed with a number of connecting blocks protruding toward the center of the inner annular surface, and a number of grooves are provided on the edge of the fixed disc body, the grooves correspond to the connecting blocks one by one, and the area of ​​the grooves is smaller than the area of ​​the connecting blocks; the fixed disc body is stacked on the brake disc body so that the axis line of the fixed disc body coincides with the axis line of the brake disc body, and each connecting block is aligned with the corresponding groove; the connecting assembly includes a spacer and a fastener, the spacer includes a sleeve body arranged in the groove, and a support plate extending outward from the top surface of the sleeve body, the support plate is pressed on the side of the fixed disc body away from the brake disc body, and the fastener is used to fasten the spacer sleeve and the brake disc body.

[0003] Although the brake disc body in the above document improves the shock absorption effect, it connects the fixed disc body and the brake disc body through a connecting assembly, and the connecting assembly is composed of multiple parts, which makes the assembly process more complicated and reduces the assembly efficiency. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a brake disc which is easy to assemble and has a simple structure in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a brake disc that is easy to assemble, comprising a fixed disc body and a brake disc body, wherein the fixed disc body and the brake disc body are detachably connected via a connecting assembly, and is characterized in that: the brake disc body comprises an inner annular surface, and a plurality of connecting blocks extending toward the center of the inner annular surface are evenly distributed on the inner annular surface, a plurality of mounting grooves for the installation of the connecting blocks are opened on the edge of the fixed disc body, a first step is provided on the inner wall of the mounting groove, an elastic retaining ring is provided on the first step, an annular groove is provided on the inner wall of the mounting groove above the first step, a retaining ring is provided in the annular groove, and the connecting block, the mounting groove, the elastic retaining ring and the retaining spring form a connecting assembly.

[0006] The above technical solution is adopted: through the setting of the elastic retaining ring, it is used to fix the brake disc body and the fixed disc body. During the assembly process, it is only necessary to insert the connecting blocks into the corresponding mounting grooves one by one, install the elastic retaining ring on the first step, make the elastic retaining ring abut against the first step, and then install the retaining ring into the annular groove to prevent the brake disc body from falling off. This connection method has a simple structure, is convenient for the staff to assemble, and improves the assembly efficiency.

[0007] A further configuration of the utility model is that a movable gap capable of allowing the brake disc to move is formed between the elastic retaining ring and the retaining spring.

[0008] The above technical solution is adopted: a movable gap is formed between the elastic retaining ring and the retaining spring, so that a movable gap is left in the axial position of the brake disc body and the fixed disc body, ensuring a larger effective contact area with the brake pad during the braking process, a shorter response time, and further improving the braking efficiency.

[0009] A further configuration of the utility model is that a plurality of weight-reducing grooves penetrating the fixed disc body are provided on the fixed disc body, the weight-reducing grooves are evenly distributed on the fixed disc body, and the weight-reducing grooves are in triangular shapes corresponding to each other.

[0010] The above technical solution is adopted: through the setting of the weight-reducing groove, the overall weight of the brake disc can be reduced and the cost can be reduced. At the same time, the shape of the weight-reducing grooves of the utility model adopts mutually corresponding triangles to achieve a lightweight design, which is lighter than the brake disc in the prior art.

[0011] A further configuration of the utility model is that the fixed disc body is provided with mutually staggered reinforcing ribs.

[0012] The above technical solution is adopted to further improve the structural strength of the fixed disc body, thereby preventing the fixed disc body from being easily bent and damaged.

[0013] A further configuration of the utility model is that the brake disc body also includes a first end face and a second end face, the first end face is provided with a plurality of first through holes spaced evenly apart along its circumferential direction, the first through holes are flared from the first end face to the second end face, the second end face is provided with a plurality of second through holes spaced evenly apart along its circumferential direction between the first through holes, the second through holes are flared from the second end face to the first end face.

[0014] The above technical solution is adopted: compared with the prior art in which the through holes on the brake disc body are vertical through holes on both end faces, the utility model arranges the first and second through holes in a flared shape to make the air circulation smoother, and air enters from the opening ends with larger diameters of the first and second through holes, and air exits from the opening ends with smaller diameters, which can quickly take away the heat generated by the brake disc body during the braking process, achieve better heat dissipation effect, improve cooling performance, and delay thermal attenuation of the brake pad.

[0015] A further configuration of the present invention is that the side walls of the first through hole and the second through hole are arranged in an inclined surface, and the opening axes of both ends of the first through hole and the second through hole are arranged parallel to each other.

[0016] The above technical solution is adopted: the first and second through holes are designed as oblique tapered holes, which increase friction and improve braking efficiency. At the same time, due to the inclined wall of the oblique tapered hole, it is difficult for particles to stay in the hole, thereby enhancing the self-cleaning ability. In addition, due to the enhanced self-cleaning ability, the braking noise is further reduced.
