According to the present invention, the surface coating has a roughness reduced to approximately 0.5 μm to 1 μm, thereby shortening the duration of intervention braking.

[0004] The brake disc products currently used in the market have a simple structure, are heavy, and have a fast temperature rise. During the use of the product, high temperatures are easily generated, which in turn affects the braking performance of the entire vehicle. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to reduce the weight of the existing brake disc, and at the same time to delete the larger connecting neck, so as to avoid the problem that the temperature of the brake disc rises too quickly during use, thereby affecting the service life, and to avoid a series of safety problems such as untimely braking due to brake disc failure.

[0006] The utility model describes a heavy truck axle brake disc with a novel structure, comprising a brake disc body, brake surfaces on both sides of the brake disc body, an annular gear ring mounting hole in the brake disc body, a wheel hub-brake disc connecting bolt mounting hole in the brake disc body, a wheel hub mounting stop in the brake disc body, and a bridge pipe mounting avoidance hole in the center of the brake disc body.

[0007] Furthermore, the braking surface includes braking surface I and braking surface II.

[0008] Furthermore, the brake disc body is annular.

[0009] Furthermore, the diameter of the hub mounting stop is the same as the diameter of the bridge tube mounting avoidance hole.

[0010] Furthermore, the brake disc body is solid.

[0011] Furthermore, the number of the annular gear ring mounting holes is at least 6.

[0012] Furthermore, the number of the wheel hub-brake disc connection bolt mounting holes is at least 10.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model discloses a heavy truck axle brake disc with a novel structure. The brake disc body is annular, and braking surfaces are provided on both sides of the brake disc body, which can cooperate with an external brake disc to perform braking operations. The gear ring mounting hole provided in the inner hole of the brake disc body cooperates with the gear ring to prevent the wheel rim from locking. The wheel hub mounting stop and mounting hole are provided in the middle of the brake disc body, and the brake disc and the wheel hub can be connected through a connecting piece. During braking, the solid brake disc is not easy to deform and crack, and has good wear resistance. The service life of the brake disc is increased, the weight of the vehicle is greatly reduced, energy is saved and consumption is reduced, carbon emissions are reduced, the weight of the existing brake disc is reduced, and a larger connecting neck is deleted at the same time, so as to avoid problems such as excessively rapid increase in the temperature of the brake disc during use, thereby affecting the service life, and avoiding a series of safety problems such as untimely braking due to brake disc failure.

[0019] Example 1

[0020] like Figure 1-2 As shown, the utility model describes a heavy truck axle brake disc of a new structure, comprising a brake disc body 1, brake surfaces 2 are arranged on both sides of the brake disc body 1, an annular gear ring mounting hole 3 is opened in the brake disc body 1, a wheel hub-brake disc connecting bolt mounting hole 4 is opened in the brake disc body 1, a wheel hub mounting stop 5 is opened in the brake disc body 1, and a bridge tube mounting avoidance hole 6 is opened in the center of the brake disc body 1.

[0021] The brake disc body 1 is the main structure, and the braking surface 2 is used to cooperate with the well brake pad to brake the vehicle; the annular gear ring mounting hole 3 is used to install the external annular gear ring, so that the annular gear ring is used to transmit torque; the wheel hub-brake disc connecting bolt mounting hole 4; through the wheel hub-brake disc connecting bolt mounting hole 4, a stable and tight connection between the brake disc and the wheel hub can be ensured; the wheel hub mounting stop 5 is used to pre-limit the installation of the machine wheel hub, so as to facilitate subsequent installation; the bridge tube installation avoidance hole 6 can avoid interference or collision between the bridge tube and other vehicle parts such as the brake disc when installing or maintaining the vehicle bridge tube.

[0022] like Figure 1-2 As shown, as an optimization, the braking surface 2 includes a braking surface I 201 and a braking surface II 202 .

[0023] Braking surface I 201 and braking surface II 202 are in direct contact with the brake pads. When the driver steps on the brake pedal, the brake pads will press the two braking surfaces 2, thereby generating friction to slow down or stop the wheels.

[0024] like Figure 1-2 As shown, as an optimization, the brake disc body 1 is annular.

[0025] The annular design increases the surface area of ​​the brake disc body 1, thereby improving the heat dissipation efficiency.

[0026] like Figure 1-2 As shown, as an optimization, the diameter of the hub mounting stop 5 and the bridge tube mounting avoidance hole 6 are the same.

[0027] The hub mounting stop 5 and the bridge tube mounting avoidance hole 6 have the same diameter, so the fit between them will be more standardized, and the same tools and equipment can be used for installation and disassembly, thereby improving work efficiency.

[0028] like Figure 1-2 As shown, as an optimization, the brake disc body is solid.

[0029] The solid brake disc is not easy to deform or crack, has good wear resistance, and increases the service life of the brake disc. The brake disc body is made of a solid high-strength, wear-resistant, and high-temperature resistant alloy material, which increases the service life of the brake disc.

[0030] like Figure 1-2 As shown, as an optimization, the number of the annular gear ring mounting holes 3 is at least 6.

[0031] As an optimization, the number of the annular gear ring mounting holes 3 is 6.

[0032] like Figure 1-2 As shown, as an optimization, the number of the wheel hub-brake disc connection bolt mounting holes 4 is at least 10.

[0033] As an optimization, the number of the wheel hub-brake disc connecting bolt mounting holes 4 is ten.

[0034] Working process or working principle:

[0035] The braking surface I 201 and the braking surface II 202 arranged on the brake disc body 1 serve as the main working planes, cooperating with the external brake caliper to drive the piston inward through the hydraulic oil, and the brake friction pad in the brake caliper contacts the braking surface 2, thereby playing a braking role. The standard parts penetrate the wheel hub-brake disc connecting bolt mounting hole 4 to connect the wheel hub.

[0036] The description of the direction and relative position relationship of the structure in the present invention, such as the description of front, back, left, right, up, and down, does not constitute a limitation of the present invention, but is only for the convenience of description.
