Description

Technical Field

[0001] This utility model relates to the field of brake caliper technology, specifically a brake caliper for a mining truck. Background Technology

[0002] Brake calipers are a key component of the braking system of mining trucks. Their main function is to transmit the braking torque of the brakes to the wheels, thereby decelerating and stopping the vehicle. When the driver presses the brake pedal, brake fluid is forced into the brake caliper, pushing the piston outward and causing the brake pads to come into close contact with the brake disc, generating friction and converting the kinetic energy of the wheel into heat energy, thus achieving the braking effect.

[0003] The operating environment of brake calipers for mining trucks is often dusty. Dust can clog the heat dissipation channels of the brake calipers, thus affecting their heat dissipation performance. With prolonged use, a large amount of heat will accumulate inside the brake caliper and is difficult to dissipate. High temperature will reduce the coefficient of friction between the brake pads and the brake disc, resulting in a decrease in braking torque, an increase in braking distance, and a prolonged braking response time, which will seriously affect the braking performance of the vehicle. Therefore, a brake caliper for mining trucks is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a brake caliper for mining trucks to solve the problem of heat accumulation on the inside of the brake caliper of mining trucks, which is difficult to dissipate.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A brake caliper for a mining truck includes a mining truck wheel, a brake disc, a brake caliper body, and bolts. The brake disc is mounted on the inner side of the mining truck wheel, and the brake caliper body is mounted on the outer side of the brake disc. A heat-conducting block is fixedly connected to the outer side of the brake caliper body. A plurality of evenly arranged heat dissipation fins are fixedly connected to the outer side of the heat-conducting block. A mounting frame is sleeved on the outer side of the heat-conducting block, and a dustproof net is fixedly connected to the inner side of the mounting frame.

[0007] Preferably, the inner side of the heat dissipation fins has a plurality of evenly arranged heat dissipation holes, and the dustproof mesh is disposed on the outer side of the heat dissipation fins.

[0008] Preferably, a threaded sleeve is provided on the inner side of the heat-conducting block, and the bolt passes through the mounting frame and is helically connected to the threaded sleeve.

[0009] Preferably, a heat insulation sleeve is fixedly connected to the inner side of the heat-conducting block in a uniformly arranged manner, and the heat insulation sleeve is fixedly connected to the threaded sleeve.

[0010] Preferably, a fixing block is fixedly connected to the outer side of the mounting frame in a uniform arrangement, and a lightweight water storage tank is fixedly connected to the side of the fixing block away from the mounting frame. A plurality of atomizing nozzles are installed at the bottom of the lightweight water storage tank in a uniform arrangement, and a feed pipe with a spiral sealing cap on the top is connected to the top of the lightweight water storage tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the structure consisting of a heat-conducting block, heat dissipation fins, a mounting frame, and a dustproof net allows the heat-conducting block to conduct heat away from the inside of the brake caliper body. The conducted heat is then dissipated through the heat dissipation fins. A dustproof net is installed on the outside of the heat-conducting block and heat dissipation fins via the mounting frame, which effectively prevents dust from adhering to the heat-conducting block and heat dissipation fins, thus solving the problem of heat accumulation on the inside of the brake caliper of mining trucks being difficult to dissipate.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0026] Please see Figure 1-6 This utility model provides a technical solution:

[0027] A brake caliper for a mining truck includes a mining truck wheel 1, a brake disc 2, a brake caliper body 3, and bolts 11. The brake disc 2 is installed on the inner side of the mining truck wheel 1, and the brake caliper body 3 is installed on the outer side of the brake disc 2. A heat-conducting block 4 is fixedly connected to the outer side of the brake caliper body 3. Several uniformly arranged heat dissipation fins 5 are fixedly connected to the outer side of the heat-conducting block 4. A mounting frame 7 is sleeved on the outer side of the heat-conducting block 4, and a dustproof net 8 is fixedly connected to the inner side of the mounting frame 7. This arrangement allows the heat-conducting block 4 to conduct heat away from the inner side of the brake caliper body 3, and the conducted heat is dissipated through the heat dissipation fins 5.

[0028] The inner side of the heat dissipation fins 5 has several evenly arranged heat dissipation holes 6, and the dust filter 8 is set on the outer side of the heat dissipation fins 5. This arrangement allows the dust filter 8 to effectively prevent dust from adhering to the heat conduction block 4 and the heat dissipation fins 5. The inner side of the heat conduction block 4 is provided with a screw sleeve 10, and the bolt 11 passes through the mounting frame 7 and is screwed to the screw sleeve 10. This arrangement allows the mounting frame 7 and the dust filter 8 to be disassembled. The inner side of the heat conduction block 4 is fixedly connected with an evenly arranged heat insulation sleeve 9, which is fixedly connected to the screw sleeve 10. This arrangement allows the heat insulation sleeve 9 to be fixedly connected to the screw sleeve 10. This can prevent the heat conducted by the heat-conducting block 4 from accumulating in the threaded sleeve 10, thereby extending the service life of the threaded sleeve 10; the outer side of the mounting frame 7 is fixedly connected with a uniformly arranged fixing block 12, and the side of the fixing block 12 away from the mounting frame 7 is fixedly connected with a lightweight water tank 13. The bottom of the lightweight water tank 13 is equipped with several uniformly arranged atomizing nozzles 14, and the top of the lightweight water tank 13 is connected to a feed pipe 15 with a spiral sealing cap on the top. This arrangement allows the sprayed water mist to settle the dust around the brake caliper body 3 and the dustproof net 8.

[0029] Workflow: The brake caliper body 3 is mounted on the brake disc 2 of the mining truck wheel 1. When the driver depresses the brake pedal, brake fluid is forced into the brake caliper body 3, pushing the piston inside the brake caliper body 3 to move outward, causing the brake pads on the mining truck wheel 1 to come into close contact with the brake disc 2, generating friction. This converts the kinetic energy of the mining truck wheel 1 into heat energy, achieving the braking effect. The mining truck wheel 1, brake disc 2, and brake caliper body 3 are all existing publicly available technologies for mining truck brake calipers. The heat-conducting block 4 can conduct heat away from the inside of the brake caliper body 3. The conducted heat is dissipated through the heat dissipation fins 5. The heat dissipation holes 6 inside the heat dissipation fins 5 can increase the contact area between the heat dissipation fins 5 and the air, thereby enhancing the heat dissipation effect of the heat dissipation fins 5. A dustproof net 8 is installed on the outside of the heat-conducting block 4 and the heat dissipation fins 5 through the mounting frame 7, which can effectively prevent dust from adhering to the heat-conducting block 4 and the heat dissipation fins 5, solving the problem of the heat accumulated inside the mining truck brake caliper being difficult to dissipate. The lightweight water tank 13 has a dustproof net 8 on the inside of the heat-conducting block 4 and the heat dissipation fins 5. Water can be sprayed from the atomizing nozzle 14. The sprayed water mist can act on the dustproof net 8 and the brake caliper body 3, causing the dust around the brake caliper body 3 and the dustproof net 8 to settle. A suitable specification for the atomizing nozzle 14 is selected so that the amount of water mist sprayed from the atomizing nozzle 14 does not cause unnecessary moisture and corrosion to the dustproof net 8 and the brake caliper body 3. The lightweight water tank 13 is set on the outside of the mounting frame 7 by the fixing block 12, and water can be added to the lightweight water tank 13 from the feed pipe 15. When replacing the dust filter 8, rotate the bolt 11 so that the thread of the bolt 11 and the threaded sleeve 10 spiral together. The bolt 11 will gradually disengage from the threaded sleeve 10 and the mounting frame 7. When the bolt 11 is completely disengaged from the mounting frame 7, move the mounting frame 7 away from the heat-conducting block 4 to disassemble the mounting frame 7 and the dust filter 8. The dust filter 8 can be installed by reversing the operation. The heat insulation sleeve 9 can prevent the heat conducted by the heat-conducting block 4 from accumulating in the threaded sleeve 10, thereby extending the service life of the threaded sleeve 10.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
