[0002] Rigid mining trucks are heavy-duty machinery used in industrial production fields such as coal mines and gold mines. Hybrid rigid mining trucks combine the advantages of traditional internal combustion engines and electric motors, generating electricity through a smaller engine and driving the entire vehicle with a power battery. They are characterized by high load capacity, high strength, and durability.

[0003] The braking system is a critical safety component of rigid mining trucks, directly affecting the vehicle's safety and reliability. Currently available rigid mining trucks require their rear axle braking system to be connected to the electric wheels to achieve safe braking of the entire vehicle.

[0004] Existing rear axle braking systems typically employ a single disc brake structure, which can result in insufficient braking force for fully loaded hybrid rigid mining trucks, creating safety hazards. Utility Model Content

[0005] In view of the defects or deficiencies in the existing technology, this utility model provides a hybrid rigid mining truck rear axle braking assembly, which can ensure the braking force of the hybrid rigid mining truck and avoid safety hazards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a hybrid rigid mining truck rear axle braking assembly, including a service brake, a brake disc, and a brake disc connecting support. The bottom end of the brake disc connecting support is fixedly connected to the flange surface of the electric wheel. There are two brake discs, namely an upper brake disc and a lower brake disc. The upper brake disc is fixed on the upper part of the brake disc connecting support, and the lower brake disc is fixedly connected to the flange surface of the electric wheel and sleeved on the lower outer side of the brake disc connecting support. There are two service brakes, namely an upper brake and a lower brake. The upper brake is correspondingly arranged with the upper brake disc, and the lower brake is correspondingly arranged with the lower brake disc.

[0007] Furthermore, the brake disc connecting support is cylindrical, and multiple bolt holes are provided on the circumference of the top surface of the brake disc connecting support. The brake disc connecting support is connected to the flange surface of the electric wheel by bolts.

[0008] Furthermore, a flange is fitted on the outer side of the upper part of the brake disc connecting support, the flange is integrally formed with the brake disc connecting support, and the upper brake disc is fixed to the flange by bolts.

[0009] Furthermore, the two brake blocks on the upper brake are located on the upper and lower sides of the upper brake disc, respectively, and the two brake blocks on the lower brake are located on the upper and lower sides of the lower brake disc, respectively.

[0010] Furthermore, the lower brake is fixed to the electric wheel housing by bolts, and a first adjusting shim is provided between the bottom surface of the lower brake and the motor housing.

[0011] Furthermore, a service brake support is provided below the upper brake, and the service brake support is fixedly connected to the bottom of the upper brake by bolts. The bottom of the service brake support is fixedly connected to the electric wheel housing by bolts.

[0012] Furthermore, a parking brake support and a second adjusting shim are provided between the upper brake and the service brake support, wherein the second adjusting shim is located between the parking brake support and the service brake support.

[0013] Furthermore, the parking brake support is a semi-circular ring, with one end wider than the other. The wider end is fixed to the lower part of the upper brake by bolts, and the other end is connected to the parking brake by bolts.

[0014] Furthermore, a clearance groove is provided at the bottom edge of the parking brake support.

[0015] Furthermore, the parking brake is configured correspondingly to the upper brake disc.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting a brake disc connecting support, this utility model can simultaneously install two brake discs on the electric wheel and install two brakes to brake the two brake discs, effectively ensuring the braking force of the rear axle braking system of the hybrid rigid mining truck, and avoiding the situation where the braking force is insufficient due to the full load of the hybrid rigid mining truck, thus avoiding safety hazards.

[0017] 2. This utility model provides a parking brake support between the service brake support and the upper brake, which can be used to fix the parking brake and realize the parking brake of the hybrid rigid mining truck.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] A typical embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, a hybrid rigid mining truck rear axle braking assembly includes a service brake, a brake disc, and a brake disc connecting support 1. The brake disc connecting support 1 is cylindrical, and multiple bolt holes are provided on the circumference of the top surface of the brake disc connecting support 1. The bottom end of the brake disc connecting support 1 is fixedly connected to the flange of the electric wheel 12 by bolts, so that the brake disc connecting support 1 can rotate with the electric wheel 12.

[0022] like Figure 3 and Figure 5 As shown, there are two brake discs, namely an upper brake disc 2 and a lower brake disc 3. A flange is fitted on the outer side of the upper part of the brake disc connecting support 1. The flange is integrally formed with the brake disc connecting support 1. The upper brake disc 2 is fixed to the flange by bolts. The lower brake disc 3 is fixedly connected to the flange surface of the electric wheel 12 by bolts. The lower brake disc 3 is fitted on the outer side of the bottom of the brake disc connecting support 1. When the electric wheel 12 rotates, the upper brake disc 2 and the lower brake disc 3 rotate synchronously.

[0023] The vehicle has two service brakes: an upper brake 4 corresponding to the upper brake disc 2 and a lower brake 5 corresponding to the lower brake disc 3. The two brake blocks on the upper brake 4 are located on the upper and lower sides of the upper brake disc 2, respectively, and the upper brake 4 is used to brake the upper brake disc 2. The two brake blocks on the lower brake 5 are located on the upper and lower sides of the lower brake disc 3, respectively, and the lower brake 5 is used to brake the lower brake disc 3.

[0024] Furthermore, the brake block on the upper brake 4 located below the upper brake disc 2, and the brake block on the lower brake 5 located above the lower brake disc 3, are both located between the upper brake disc 2 and the lower brake disc 3.

[0025] The lower brake 5 is fixed to the housing of the electric wheel 12 by bolts. The lower brake 5 does not rotate with the electric wheel 12. A first adjusting shim 6 is provided between the bottom surface of the lower brake 5 and the housing of the motor. By replacing the first adjusting shim 6 with different thicknesses, the gap between the lower brake disc 3 and the two brake blocks of the lower brake 5 can be adjusted so that the lower brake disc 3 is located between the two brake blocks of the lower brake 5, thus avoiding uneven gap from affecting the braking force of the lower brake 5.

[0026] Since there is a certain distance between the bottom of the upper brake 4 and the electric wheel 12, in order to make the upper brake 4 correspond to the upper brake disc 2, a service brake support 7 is provided below the upper brake 4. The service brake support 7 is fixedly connected to the bottom of the upper brake 4 by bolts, and the bottom of the service brake support 7 is fixedly connected to the housing of the electric wheel 12 by bolts. The upper brake 4 does not rotate with the electric wheel 12. By setting the service brake support 7, the height of the upper brake 4 is consistent with that of the upper brake disc 2.

[0027] Furthermore, a parking brake support 8 and a second adjusting shim 9 are also provided between the upper brake 4 and the service brake support 7. The second adjusting shim 9 is located between the parking brake support 8 and the service brake support 7. By replacing the second adjusting shim 9 with different thicknesses, the gap between the upper brake disc 2 and the two brake blocks of the upper brake 4 can be adjusted so that the upper brake disc 2 is located between the two brake blocks of the upper brake 4, thus avoiding uneven gaps from affecting the braking force of the upper brake 4.

[0028] The parking brake support 8 is used to fix the parking brake 10. The parking brake 10 is correspondingly set with the upper brake disc 2 and is used to apply parking brake to the rigid mining truck. Specifically, as shown... Figure 4 As shown, the parking brake support 8 is a semi-circular ring, with one end wider than the other. The wider end is fixed to the bottom of the upper brake 4 by bolts, and the other end is connected to the parking brake 10 by bolts. A clearance groove 11 is provided at the bottom edge of the parking brake support 8. When the parking brake support 8 is fixed to the bottom of the upper brake 4, the clearance groove 11 is used to avoid the lower brake disc 3, preventing interference between the parking brake support 8 and the lower brake disc 3.

[0029] In this embodiment, both the service brake and the parking brake 10 are commercially available service brakes and parking brakes to ensure the universality of the braking assembly.

[0030] By setting up brake disc connecting supports, two brake discs can be installed on the electric wheel at the same time, and two brakes can be set up to brake the two brake discs. This effectively ensures the braking force of the rear axle braking system of the hybrid rigid mining truck and avoids the situation where the braking force is insufficient due to the full load of the hybrid rigid mining truck, thus avoiding safety hazards.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
