Description

Technical Field

[0001] The invention relates to the technical field of open-pit coal mine dump trucks, in particular to a dust blocking and noise reduction device for an anti-lock braking system of a tire of an open-pit coal mine dump truck. Background Art

[0002] The tire anti-lock braking system of large dump trucks in open-pit coal mines generally refers to ABS. Its main function is to prevent the four wheels from being locked during braking and reduce the occurrence of accidents. When the car suddenly encounters a situation and brakes, more than 90% of drivers tend to step on the brake pedal to the bottom to brake suddenly. At this time, the car is very likely to slip and slide sideways, which is commonly known as "tail swinging", which is a phenomenon that is very likely to cause a car accident.

[0003] The current open-pit coal mine large dump truck tire anti-lock braking device has the following disadvantages when in use: the device is prone to adhere to a thick layer of dust when in use, and if the accumulated dust cannot be cleaned off in time, it will affect the operation. Summary of the invention

[0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To achieve the above-mentioned purpose, the present invention proposes a dust and noise reduction device for an anti-lock braking system of an open-pit coal mine dump truck tire, comprising a brake disc, a brake caliper is arranged on the top of the brake disc, a dust and noise reduction cover is arranged on the surface of the brake caliper, the dust and noise reduction cover comprises a dust and noise reduction net arranged above the brake caliper and a fixed side wall arranged in the direction of the side wall of the brake caliper, the dust and noise reduction net is integrally connected with the fixed side wall, and a mesh structure for dissipating heat for the brake caliper is arranged on the dust and noise reduction net, and a fixed structure is arranged between the fixed side wall and the brake caliper.

[0006] The present invention arranges a dust-blocking and noise-reducing cover on the brake disc, which can prevent dust from falling on the brake caliper. At the same time, because the sound passes through the dust-blocking and noise-reducing net during the transmission process, the mesh structure makes the sound transmission path tortuous without affecting the heat dissipation of the brake caliper, thereby absorbing the vibration energy in the sound transmission process and reducing the noise generated by the brake caliper during the braking process.

[0007] Optionally, the dust-blocking and noise-reducing net is configured as a louver-like structure consisting of a plurality of parallel iron sheets at equal intervals, and a heat dissipation gap is provided between two adjacent iron sheets.

[0008] Furthermore, each of the iron sheets is tilted, and a cross section of each iron sheet is tilted at an angle of 45° to the horizontal direction.

[0009] Furthermore, the dust-blocking and noise-reducing net is configured as a double-layer net structure including an upper net and a lower net, and both the upper net and the lower net are formed into a louver-like structure by a plurality of parallel and equally spaced iron sheets.

[0010] Furthermore, the cross section of the iron sheet of the upper mesh is inclined at an angle of 45° to the horizontal direction, and the cross section of the iron sheet of the lower mesh is inclined at an angle of 135° to the horizontal direction.

[0011] Furthermore, the horizontal projection width of each iron sheet is 0.5-1.5 cm, and the width of each heat dissipation gap is set to 2-3 cm.

[0012] Furthermore, the distance between the fixed side wall and the brake caliper is set to 1.5-3 cm.

[0013] Furthermore, the fixing structure includes a fixing plate arranged at the bottom end of the fixing side wall corresponding to the bottom surface of the brake caliper, the fixing plate is arranged parallel to the bottom surface of the caliper, and the bottom surface of the brake caliper and the fixing plate are detachably fixed by bolts.

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The present invention provides a dust and noise reduction device for an anti-lock braking system of a tire of an open-pit coal mine dump truck. Figures 1 to 4 Elaborate in detail.

[0024] A dust and noise reduction device for an anti-lock braking system of an open-pit coal mine dump truck tire comprises a brake disc 1, a brake caliper 2 is arranged on the top of the brake disc 1, a dust and noise reduction cover 3 is arranged on the surface of the brake caliper 2, the dust and noise reduction cover 3 comprises a dust and noise reduction net 31 arranged above the brake caliper 2 and a fixed side wall 32 arranged in the side wall direction of the brake caliper 2, the dust and noise reduction net 31 is integrally connected with the fixed side wall 32, and a mesh structure for dissipating heat for the brake caliper 2 is arranged on the dust and noise reduction net 31, and a fixed structure 4 is arranged between the fixed side wall 32 and the brake caliper 2.

[0025] The present invention arranges a dust-blocking and noise-reducing cover 3 on the brake disc 1, which can prevent dust from falling on the brake caliper 2. At the same time, since the sound passes through the dust-blocking and noise-reducing net 31 during the transmission process, the mesh structure makes the sound transmission path tortuous without affecting the heat dissipation of the brake caliper 2, thereby absorbing the vibration energy during the sound transmission process, thereby reducing the noise generated by the brake caliper 2 during the braking process.

[0026] In some embodiments, the dust-blocking and noise-reducing net 31 is configured as a louver-like structure composed of a plurality of parallel and equally spaced iron sheets 311, and a heat dissipation gap 312 is provided between two adjacent iron sheets 311. The louver-like structure can shield dust above the brake caliper 2, and at the same time, the louver-like structure can form a reflection surface between adjacent iron sheets 311. During the transmission process, the sound will be transmitted multiple times between the reflection surfaces, thereby absorbing the energy carried in the sound transmission process, thereby further reducing the noise.

[0027] In one embodiment, each iron sheet 311 is tilted, and a cross section of each iron sheet 311 is tilted at an angle of 45° to the horizontal direction.

[0028] In some embodiments, the dust-blocking and noise-reducing net 31 is configured as a double-layer net structure including an upper net 313 and a lower net 314, and both the upper net 313 and the lower net 314 are formed of a plurality of parallel iron sheets 311 at equal intervals to form a louver-like structure. On the one hand, the double-layer structure can play a secondary shielding role for the dust generated by the heat dissipation gap 312 between the single-layer iron sheets 311, thereby enhancing the dust-blocking effect; on the other hand, during use, the double-layer louver-like structure can further cause the sound to be reflected multiple times during the transmission process, further absorbing the energy carried during the sound transmission process, thereby enhancing the noise reduction effect.

[0029] In some embodiments, the cross section of the iron sheet 311 of the upper mesh 313 is inclined at an angle of 45° to the horizontal direction, and the cross section of the iron sheet 311 of the lower mesh 314 is inclined at an angle of 135° to the horizontal direction.

[0030] In some embodiments, the horizontal projection width of each iron sheet 311 is 0.5-1.5 cm, and the width of each heat dissipation gap 312 is set to 2-3 cm. The heat dissipation gap 312 is set slightly wider than the horizontal projection of the iron sheet 311 to ensure that the air flow is sufficient to dissipate heat for the brake caliper 2.

[0031] In some embodiments, the distance between the fixed side wall 32 and the brake caliper 2 is set to 1.5-3 cm. Leaving enough space around the brake caliper 2 can leave enough flow space for air, thereby taking away the heat on the surface of the brake caliper 2.

[0032] In some embodiments, the fixing structure 4 includes a fixing plate 41 disposed at the bottom end of the fixing side wall 32 corresponding to the bottom surface of the brake caliper 2, the fixing plate 41 is disposed parallel to the bottom surface of the caliper, and the bottom surface of the brake caliper 2 and the fixing plate 41 are detachably fixed by bolts 42. The use of bolts 42 for detachable fixing can facilitate disassembly and installation.
