[0033] The utility model relates to a kind of brake heat dissipation devices of mine trackless rubber-tyred vehicle, as shown in figure, comprising: Figures 1 to 5

[0037] Fixed piece 5 is installed on clamp body mechanism 1, and at least one extension piece 51 is provided on fixed piece 5, and assembling mechanism 6 is provided on each extension piece 51;

[0038] ​A transmission shaft 7 is rotatably installed on the assembling mechanism 6, and a transmission wheel 8 is coaxially installed on the transmission shaft 7, and the transmission wheel 8 is connected with the transmission disc 4 through friction force matching, when the transmission disc 4 rotates, the transmission wheel 8 rotates with it, thereby driving the transmission shaft 7 to rotate;

[0039] An installation piece 9 is coaxially installed on the transmission shaft 7, and the installation piece 9 is installed with a heat dissipation leaf 10, and the heat dissipation leaf 10 and the installation piece 9 rotate synchronously with the transmission shaft 7, and the design of the heat dissipation leaf 10 can generate airflow when the transmission shaft 7 rotates, thereby dissipating heat for the disc body mechanism 2;

[0040] The working principle of the device is as follows:

[0041] When the mine trackless rubber-tyred vehicle brakes, the caliper body mechanism 1 clamps the disc body mechanism 2 to generate braking force, and the disc body mechanism 2 rotates synchronously with the hub to drive the extension shaft 3 and the transmission disc 4 to rotate, and the transmission disc 4 drives the transmission wheel 8 to rotate through friction force, thereby driving the transmission shaft 7 to rotate, and the rotation of the transmission shaft 7 drives the installation piece 9 and the heat dissipation leaf 10 to rotate synchronously, generating airflow to dissipate heat for the disc body mechanism 2, preventing the accumulation of heat generated by braking from causing a decrease in braking performance;

[0042] The caliper body mechanism 1 is installed on the axle housing to realize the braking function, and the disc body mechanism 2 is installed on the hub to transmit the braking force, and the two cooperate to ensure reliable braking of the vehicle, the extension shaft 3 is coaxially installed with the disc body mechanism 2 and drives the transmission disc 4 to rotate synchronously, laying a foundation for subsequent heat dissipation power transmission, the fixing piece 5 is installed on the caliper body mechanism 1, the assembling mechanism 6 on the extension piece 51 thereof provides stable support for the transmission shaft 7, the transmission wheel 8 on the transmission shaft 7 matches with the transmission disc 4 through friction force, which can efficiently utilize the rotation of the disc body mechanism 2 to drive the transmission shaft 7 to rotate, and the installation piece 9 and the heat dissipation leaf 10 installed on the transmission shaft 7 rotate synchronously to generate airflow, which can dissipate heat for the disc body mechanism 2 in time, effectively preventing the accumulation of heat generated by braking from causing a decrease in braking performance, and improving the stability and reliability of the braking system.

[0043] As a preferred solution, as shown in Figures 1 to 5 The assembling mechanism 6 comprises:

[0044] A moving piece 61 is arranged in the inner groove of the extension piece 51, and the moving piece 61 is slidably installed along the length direction of the extension piece 51, and the transmission shaft 7 is rotatably installed on the moving piece 61;

[0045] A spring 62 is installed at one end of the moving piece 61 and at the other end of the inner groove wall of the extension piece 51;

[0046] A positioning column 63 is arranged in the length direction of the inner groove of the extension piece 51, and the moving piece 61 is slidably installed with the positioning column 63;

[0047] The moving part 61 is arranged in the groove of the extending part 51 and can slide along the length direction of the groove, and the transmission shaft 7 is rotatably arranged on the moving part, which can flexibly adjust the position of the transmission shaft 7 and better adapt to the matching requirement between the transmission disc 4 and the transmission wheel 8. The spring 62 is connected to one end of the moving part 61 and the other end of the groove wall of the extending part 51, which can provide elastic support for the moving part 61, ensure that the transmission wheel 8 and the transmission disc 4 always maintain appropriate friction, guarantee the stability and high efficiency of power transmission, and at the same time ensure that the transmission relationship between the transmission wheel 8 and the transmission disc 4 remains stable when the positions of the transmission wheel 8 and the transmission disc 4 vibrate, and at the same time will not cause damage to the structure.

[0048] As a preferred solution, as shown in Figures 1 to 5 The fixed part 5 is provided with an inner hole, and the inner hole of the fixed part 5 is coaxially arranged with the extending shaft 3. The diameter of the inner hole of the fixed part 5 is greater than the outer diameter of the extending shaft 3.

[0049] The inner hole with a larger diameter provides sufficient space for the rotation of the extending shaft 3, reduces the risk of interference between the two, and even if the vehicle bounces or the components are slightly displaced during driving, the extending shaft 3 can still rotate freely in the hole and will not be damaged due to contact and collision with the fixed part 5. At the same time, it is also convenient for installation and disassembly, and reduces the difficulty of maintenance.

[0050] As a preferred solution, as shown in Figures 1 to 3 The disc body mechanism 2 comprises:

[0051] Two brake discs 21 are coaxially arranged through the connecting column group 22 arranged in the middle, and the brake disc 21 is provided with a plurality of heat dissipation holes;

[0052] The mounting disc 23 is coaxially arranged on one brake disc 21, and the mounting disc 23 is provided with an assembly hole. The mounting disc 23 is used for mounting the brake disc 21 and the hub, and the extending shaft 3 is coaxially arranged on the mounting disc 23.

[0053] The heat dissipation hole of the brake disc 21 is an inclined hole arranged obliquely to the end surface of the brake disc 21.

[0054] The two brake discs 21 are coaxially arranged through the connecting column group 22, which enhances the overall stability and structural strength of the disc body mechanism, ensures reliable performance during transmission of braking force, and increases the heat dissipation area of the brake disc 21. A plurality of heat dissipation holes are arranged on the brake disc, which further increases the heat dissipation area of the brake disc, which is beneficial to the rapid dissipation of heat. In particular, the heat dissipation hole is an inclined hole arranged obliquely to the end surface of the brake disc 21. This design makes the airflow form a more complex flow path when passing through the hole, prolonging the contact time of the airflow with the brake disc.

[0055] As a preferred solution, as shown in Figures 1 to 3 The clamp body mechanism 1 comprises:

[0056] Two clamp body pieces 11 are fixedly installed by bolts 12, and the middle part of the two clamp body pieces 11 is provided with a slot for accommodating the disc body mechanism 2.

[0057] Two pistons 13 are symmetrically installed on the two clamp body pieces 11 respectively, and the output end of the piston 13 is provided with a friction block 14.

[0058] The slot in the middle part accurately accommodates the disc body mechanism 2, and the brake force can be effectively transmitted during braking. The two pistons 13 symmetrically installed on the clamp body pieces 11 control the output end of the friction block 14. When the vehicle brakes, the piston 13 pushes the friction block 14 to tightly adhere to the disc body mechanism 2, thereby providing strong and uniform brake force, ensuring the reliability and stability of the braking effect. The symmetric design makes the pressure generated during braking evenly distributed on the disc body mechanism 2, avoids the disc body mechanism 2 from being excessively worn due to uneven force, prolongs the service life of the disc body mechanism, and at the same time ensures the stability of the vehicle during braking.

[0059] As a preferred solution, as shown in Figure 3 The inside of the clamp body piece 11 is provided with a plurality of equidistantly distributed cooling fins 15.

[0060] During braking, a large amount of heat is generated by friction. The cooling fins 15 can effectively increase the heat dissipation area of the clamp body piece 11 and accelerate the heat dissipation speed. The equidistant distribution design can make the heat evenly conduct from the clamp body piece 11 to the cooling fins 15, avoid local overheating, and ensure the overall temperature stability of the clamp body piece.

[0061] The installation mode, connection mode or setting mode of the mine trackless rubber-tyred vehicle brake heat dissipation device are all common mechanical modes, and as long as the beneficial effects can be achieved, they can be implemented.

[0062] The above is only a preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, on the premise of not departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be regarded as the protection scope of the present application.
