Description

Caliper-type electric dust collector and vehicle braking device including the same

[0001] The present invention relates to a caliper-type electric dust collector and a vehicle braking device including the same.

[0002] It is generally known that fine dust generated during automobile driving is generated in large quantities not only by exhaust gases but also by wear and tear on tires and brake pads. In order to reduce fine dust in cities, it is necessary to reduce fine dust generated by automobiles, which are one of the main sources of mobile pollution.

[0003] Specifically, the braking system of a vehicle generates braking force through frictional force generated by pressing brake pads against a brake disc that rotates along with the vehicle's wheels. When the vehicle is braking, friction between the brake disc and the brake pad causes wear of the brake pad, generating various types of dust that are harmful to the human body.

[0004] The fine dust generated by brake pad wear is extremely small and contains harmful substances, which are known to have detrimental effects on the human body, including respiratory, eye, and skin diseases. Therefore, technological development to address these issues is urgently needed.

[0005] Due to the recent increase in hydrogen and electric vehicles, the impact of fine dust generated by exhaust gases is expected to gradually decrease. However, since hydrogen and electric vehicles use the same braking method as internal combustion vehicles, fine dust generated by tire and brake pad wear still occurs.

[0006] Previously, devices were developed to capture fine dust generated by tire and brake pad wear by installing them around automobile wheels, and most of them use a filter method.

[0007] However, filter-type air purifiers struggle to capture fine dust after a certain period of time due to pressure loss caused by the filter, making it difficult to effectively capture fine dust. Furthermore, fiber filters are difficult to clean and regenerate, requiring frequent replacement, making maintenance difficult.

[0008] The technical problem to be achieved by the present invention is to provide a caliper-type electric dust collector capable of efficiently collecting dust particles from a brake disc and pad by including a guide part movably arranged on a brake disc, and a vehicle braking device including the same.

[0009] The problems addressed by the present invention are not limited to those mentioned above. Other problems and advantages of the present invention not mentioned above can be understood through the following description and will be more clearly understood through the embodiments of the present invention.

[0048] FIG. 1 is a schematic drawing of a caliper-type electric precipitator according to one embodiment of the present invention, FIG. 2 is a drawing for illustrating a state of use of a caliper-type electric precipitator according to one embodiment of the present invention, and FIG. 3 is a drawing illustrating a state in which a guide part according to one embodiment of the present invention is arranged in a first position.

[0049] FIG. 4 is a drawing showing a state in which a guide part according to one embodiment of the present invention is placed at position 2, FIG. 5 is a drawing showing a dust collecting part according to one embodiment of the present invention, and FIG. 6 is a block diagram for explaining a control part according to one embodiment of the present invention.

[0050] A caliper-type electric dust collector (1) according to one embodiment of the present invention relates to a device that collects particles (P) generated by friction between a brake disc (BD) and a brake pad (not shown in the drawing) of a caliper (100) in a vehicle that performs braking, including a brake disc (BD) and a caliper (100), by the force of an electric field.

[0051] Referring to FIGS. 1 to 4, a caliper-type electric dust collector (1) (hereinafter referred to as “electric dust collector (1)”) according to one embodiment of the present invention may include a brake disc (BD), a caliper unit (100), a dust collector (200), a guide unit (300), a driving unit (400), and a control unit (500).

[0052] A brake disc (BD) is connected to rotate in conjunction with the vehicle's wheels. Specifically, when the wheels rotate, the brake disc (BD) also rotates integrally with the wheels, and when braking force is applied to the brake disc (BD), the rotational speed of the wheels operating integrally with the brake disc (BD) also decreases.

[0053] In this specification, 'wheel' may be interpreted as a wheel of a vehicle.

[0054] The brake disc (BD) together with the caliper unit (100) constitute the braking system of a vehicle. The caliper unit (100) includes brake pads that move according to the user's operation, and according to the user's operation, the brake pads selectively contact the brake disc (BD) to provide frictional force, thereby applying braking force to the brake disc (BD) or the wheel.

[0055] Referring to FIGS. 1 and 2, a caliper portion (100) according to one embodiment of the present invention is disposed on one side of the circumference of a brake disc (BD), and can apply braking force to the brake disc (BD) by bringing the brake pad into close contact with the brake disc (BD) according to a user's operation.

[0056] In one embodiment, the caliper portion (100) may be positioned on the front side of the vehicle, but is not limited thereto.

[0057] The brake disc (BD) and caliper (100) are applied in various structures to conventional vehicle braking devices, and therefore, a detailed description of the internal structure and operating principle of the brake disc (BD) and caliper (100) is omitted.

[0058] Referring to FIGS. 1, 2, and 5, a dust collecting unit (200) according to one embodiment of the present invention is configured to electrostatically collect particles (P) generated by friction between a brake disc (BD) and a caliper unit (100), and may include a first dust collecting plate (210), a second dust collecting plate (220), a high voltage applying unit (230), and a cover unit (250).

[0059] Since the particles (P) generated from the brake pad are already charged by friction between the brake pad and the brake disc (BD), there is no need to provide a separate charging device for electric dust collection, and the particles (P) can be captured by the force of an electric field by placing a dust collection unit (200) at the rear of the caliper unit (100) from which the charged particles (P) are discharged.

[0060] Since particles (P) generated from the brake pad are discharged from the caliper part (100) in the direction of rotation of the brake disc (BD), the caliper-type electric dust collector (1) can easily collect particles (P) by arranging the dust collector (200) on one side of the caliper part (100) without a separate air flow device such as a fan.

[0061] The dust collector (200) can be spaced apart from the caliper (100), and specifically, the caliper (100) and the dust collector (200) can be spaced apart in the circumferential direction of the brake disc (BD).

[0062] In an optional embodiment, a plurality of dust collectors (200) may be provided, and the plurality of dust collectors (200) may be arranged adjacent to each end of the caliper unit (100).

[0063] Referring to Fig. 5, the first dust collecting plate (210) can receive a high voltage from a high voltage applying unit (230). In addition, the second dust collecting plate (220) can be grounded and spaced apart from the first dust collecting plate (210).

[0064] The first dust collecting plate (210) and the second dust collecting plate (220) can be spaced apart from each other in parallel along the thickness direction of the brake disc (BD).

[0065] Specifically, a plurality of first dust collector plates (210) and second dust collector plates (220) may be provided, and a plurality of first dust collector plates (210) and second dust collector plates (220) may be spaced apart from each other so as to be repeated along the thickness direction of the brake disc (BD).

[0066] For example, one second dust collecting plate (220) may be placed between two first dust collecting plates (210), and one first dust collecting plate (210) may be placed between two second dust collecting plates (220).

[0067] One side of the first dust collecting plate (210) and one side of the second dust collecting plate (220) can be parallel to one side of the brake disc (BD), and thus a wide contact area can be secured between the particles (P) discharged along one side of the brake disc (BD) and the first dust collecting plate (210) or the second dust collecting plate (220), so that electric dust collection of the particles (P) can be effectively performed.

[0068] The charged particles (P) generated between the brake disc (BD) and the caliper (100) move toward the dust collector (200) along the rotational direction of the brake disc (BD), and the charged particles (P) can move to the gap between the first dust collector (210) and the second dust collector (220).

[0069] Since the first dust collecting plate (210) is applied with high voltage and the second dust collecting plate (220) is grounded, an electric field is formed in the separation space due to the potential difference between the first dust collecting plate (210) and the second dust collecting plate (220), and charged particles (P) moving to the separation space can be collected in the dust collecting unit (200) by the electric field.

[0070] As an optional embodiment, a separately provided filter may be placed between the first dust collecting plate (210) and the second dust collecting plate (220), thereby effectively capturing particles (P) along with dust collection of particles (P) by an electric field.

[0071] Referring to FIG. 6, a high voltage application unit (230) according to one embodiment of the present invention can receive an electrical signal from a control unit (500) and adjust the magnitude of the voltage applied to the first dust collecting plate (210).

[0072] The control unit (500) can receive information about the speed of the vehicle or the rotational speed of the brake disc (BD) and control the magnitude of the voltage that the high voltage application unit (230) provides to the first dust collecting plate (210). Specifically, when the speed of the vehicle or the rotational speed of the brake disc (BD) is high, the high voltage application unit (230) can reduce the magnitude of the voltage that the high voltage application unit (230) provides to the first dust collecting plate (210).

[0073] Additionally, when the speed of the vehicle or the rotational speed of the brake disc (BD) is low, the magnitude of the voltage provided by the high voltage application unit (230) to the first dust collecting plate (210) can be increased.

[0074] Accordingly, when the vehicle speed is high, the charge amount of the particles (P) is high due to the strong friction between the brake disc (BD) and the caliper (100), so even if the high voltage application unit (230) applies a relatively weak high voltage to the first dust collecting plate (210) according to the control signal of the control unit (500), the particles (P) with a high charge amount can be easily collected with only the weak electric field generated in the dust collecting unit (200).

[0075] In addition, when the speed of the vehicle is low, even if the charge amount of the particles (P) is not high due to relatively little friction between the brake disc (BD) and the caliper (100), the high voltage application unit (230) can easily collect particles (P) with low charge amounts by applying a relatively strong high voltage to the first dust collecting plate (210) according to the control signal of the control unit (500).

[0076] Through this, it is possible to appropriately adjust the voltage applied to the first dust collecting plate (210) by the high voltage applying unit (230) according to the charge amount of the particle (P), thereby minimizing the power consumption of the dust collecting unit (200) while increasing the dust collecting performance of the dust collecting unit (200).

[0077] Referring to FIG. 5, a cover part (250) according to one embodiment of the present invention can accommodate a first dust collecting plate (210) and a second dust collecting plate (220) inside, and can be formed to extend along the circumferential direction of a brake disc (BD).

[0078] The length of the cover portion (250) extending along the circumferential direction of the brake disc (BD) can be formed to be relatively longer than the length of the first dust collecting plate (210) and the second dust collecting plate (220) extending along the circumferential direction of the brake disc (BD).

[0079] Accordingly, when particles (P) are introduced into the space where the first dust collecting plate (210) and the second dust collecting plate (220) are located, the cover part (250) separates the first dust collecting plate (210) and the second dust collecting plate (220) from the external space, thereby preventing the phenomenon of particles (P) being separated from the electric field formed by the first dust collecting plate (210) and the second dust collecting plate (220) due to external factors such as wind (W).

[0080] The cover part (250) according to one embodiment of the present invention may be spaced apart from the caliper part (100). Specifically, one end of the cover part (250) facing the caliper part (100) and one end of the caliper part (100) facing the cover part (250) may be spaced apart from each other by a preset distance.

[0081] As a result, the brake disc (BD) can be exposed to the outside through the separation space between the caliper part (100) and the cover part (250), so that the brake disc (BD) can be easily cooled by being exposed to the outside immediately after friction with the caliper part (100).

[0082] The position of the cover part (250) according to one embodiment of the present invention can be fixed. Specifically, the cover part (250) can be connected to at least one of the brake disc (BD), the caliper part (100), the first dust collecting plate (210), or the second dust collecting plate (220) in a fixed position.

[0083] As a result, the cover part (250) stably covers the first dust collecting plate (210) and the second dust collecting plate (220), thereby guiding the particles (P) flowing into the inside of the cover part (250) to stably flow into the space between the first dust collecting plate (210) and the second dust collecting plate (220).

[0084] Referring to FIGS. 1 to 4, a guide portion (300) according to one embodiment of the present invention provides a movement path for particles (P) and can selectively cover the space between the caliper portion (100) and the dust collection portion (200).

[0085] In the following specification, the 'first position' may be interpreted as the position of the guide portion (300) arranged to cover the caliper portion (100), and the 'second position' may be interpreted as the position of the guide portion (300) arranged spaced apart from the caliper portion (100).

[0086] However, it is not limited thereto, and the 'first position' can be interpreted as the position of the guide part (300) arranged to cover a preset area of ​​the caliper part (100), and the 'second position' can be interpreted as the position of the guide part (300) arranged to cover a relatively narrower area than the above-described area of ​​the caliper part (100).

[0087] For example, when the guide part (300) moves to the first position, the guide part (300) can cover more than half of the outer surface of the caliper part (100), and when the guide part (300) moves to the second position, the guide part (300) can cover less than half of the outer surface of the caliper part (100).

[0088] Referring to FIGS. 2 to 4, the guide portion (300) can move along the circumferential direction of the brake disc (BD).

[0089] In one embodiment, the guide unit (300) can receive an electric signal from the control unit (500) and move along the circumferential direction of the brake disc (BD).

[0090] Specifically, the guide part (300) can receive power from the driving part (400) and move along the circumference of the brake disc (BD), and the driving part (400) can receive an electric signal from the control part (500) and adjust the position of the guide part (300).

[0091] Referring to FIG. 3, the guide part (300) can selectively accommodate the caliper part (100) according to an electrical signal from the control part (500).

[0092] The width in the thickness direction of the brake disc (BD) of the guide portion (300) may be relatively larger than the width in the thickness direction of the brake disc (BD) of the caliper portion (100) and the width in the thickness direction of the brake disc (BD) of the dust collector portion (200).

[0093] The guide part (300) can move along the circumferential direction of the brake disc (BD), and when the guide part (300) moves to the first position, the outer surface of the caliper part (100) can be covered, and when the guide part (300) moves to the second position, the outer surface of the caliper part (100) can be exposed to the outside.

[0094] Referring to FIG. 3, the guide part (300) receives power from the driving part (400) and moves to the first position, thereby covering the outer surface of the caliper part (100).

[0095] As a result, the guide part (300) partitions the caliper part (100) from the external space, thereby restricting the wind (W) directed toward the caliper part (100) due to the vehicle driving, etc. from flowing into the caliper part (100), thereby guiding the movement path of the particles (P) generated inside the caliper part (100) so that they flow toward the dust collection part (200) without being affected by the wind (W), etc.

[0096] Referring to FIG. 4, the guide part (300) receives power from the driving part (400) and moves to the second position, thereby allowing the caliper part (100) to be exposed to the outside.

[0097] As a result, the wind (W) flows into the internal space of the caliper part (100) or the space between the caliper part (100) and the dust collector (200), thereby improving the contact area between the wind (W) and the brake disc (BD), thereby increasing the cooling efficiency of the brake disc (BD).

[0098] In an optional embodiment, a plurality of guide parts (300) may be provided, and each of the plurality of guide parts (300) may receive power from the driving part (400) and move independently along the circumferential direction of the brake disc (BD).

[0099] In one embodiment, the position of the guide part (300) can be adjusted according to the rotation speed of the brake disc (BD), the temperature of the brake disc (BD), the amount of particles (P) generated, or the amount of charge of the particles (P), and a detailed description thereof will be provided later.

[0100] The guide part (300) can be movably connected to one side of the cover part (250). As a result, the guide part (300) can move relative to the cover part (250) fixed to the brake disc (BD), thereby selectively covering or exposing the caliper part (100) to the outside.

[0101] In an optional embodiment, the guide portion (300) may be movably connected to one side of the caliper portion (100). As a result, the guide portion (300) may move relative to the caliper portion (100) fixed to the brake disc (BD), thereby selectively covering or exposing the caliper portion (100) to the outside.

[0102] In an optional embodiment, the guide portion (300) may be movably connected to one side of the brake disc (BD). This allows the guide portion (300) to move relative to the brake disc (BD), thereby selectively covering or exposing the caliper portion (100) fixed to the brake disc (BD) to the outside.

[0103] Referring to FIGS. 1 to 4, the guide portion (300) can be arranged to surround one end of the cover portion (250) facing the caliper portion (100).

[0104] Specifically, the guide part (300) can be arranged to surround one end of the cover part (250) facing the caliper part (100) and one end of the caliper part (100) facing the cover part (250).

[0105] Accordingly, since the guide part (300) covers the space between the one end of the cover part (250) and the one end of the caliper part (100), the particle (P) generated in the caliper part (100) is prevented from escaping to the outside from the space between the one end of the caliper part (100) and the one end of the cover part (250) in the process of moving toward the cover part (250), thereby improving the particle (P) collection performance.

[0106] In one embodiment, the length of the guide portion (300) extending along the circumferential direction of the brake disc (BD) may be equal to or relatively greater than the distance between the one end of the cover portion (250) and the one end of the caliper portion (100).

[0107] In one embodiment, the length of the guide portion (300) extending along the circumferential direction of the brake disc (BD) may be relatively smaller than the length of the caliper portion (100) extending along the circumferential direction of the brake disc.

[0108] In one embodiment, the length of the guide portion (300) extending along the circumferential direction of the brake disc (BD) may be greater than half the length of the caliper portion (100) extending along the circumferential direction of the brake disc.

[0109] The guide portion (300) may be formed of a material with high heat dissipation performance and high thermal conductivity. Accordingly, even when the guide portion (300) is positioned at the first position and covers the caliper portion (100), the heat generated in the caliper portion (100) is allowed to be dissipated to the outside, thereby guiding the movement path of the particles (P) and ensuring cooling efficiency of the brake disc (BD).

[0110] Referring to FIGS. 1, 2, and 6, an electric dust collector (1) according to one embodiment of the present invention may include a control unit (500) capable of adjusting the position of a guide unit (300).

[0111] Specifically, the control unit (500) can adjust the position of the guide unit (300) on the brake disc (BD), and the control unit (500) can adjust the position of the guide unit (300) by controlling the operation of the driving unit (400) that provides power to the guide unit (300).

[0112] The control unit (500) can obtain at least one of the vehicle speed information, the rotation speed information of the brake disc (BD), the temperature information of the brake disc (BD), the information on the amount of particles (P) generated, or the information on the charge amount of the particles (P) from the sensor unit (600) to be described later, and can adjust the position of the guide unit (300) using the obtained information.

[0113] Referring to FIG. 2, FIG. 3, and FIG. 6, the control unit (500) can control the operation of the driving unit (400) to place the guide unit (300) at the first position so that the guide unit (300) covers the caliper unit (100).

[0114] When the vehicle speed is high or the brake disc (BD) rotates at high speed, the control unit (500) can control the operation of the driving unit (400) to place the guide unit (300) in the first position so that the guide unit (300) covers the caliper unit (100).

[0115] As a result, the wind (W) is restricted from flowing inside the caliper section (100), thereby preventing the wind (W) from flowing toward the dust collector (200) and being blown outward, thereby increasing the particle (P) collection efficiency.

[0116] When the amount of particles (P) generated between the brake disc (BD) and the caliper part (100) is large, the control part (500) can control the operation of the driving part (400) to place the guide part (300) in the first position so that the guide part (300) covers the caliper part (100).

[0117] When the charge of the particle (P) is low, the control unit (500) can control the operation of the driving unit (400) to place the guide unit (300) at the first position so that the guide unit (300) covers the caliper unit (100).

[0118] Due to this, even if the charge of the particles (P) is low, the guide part (300) guides a large amount of particles (P) to flow toward the dust collecting part (200), thereby increasing the amount of particles (P) captured in the dust collecting part (200).

[0119] Referring to FIG. 2, FIG. 4, and FIG. 6, the control unit (500) can control the operation of the driving unit (400) to place the guide unit (300) at the second position so that the caliper unit (100) is exposed to the outside.

[0120] When the temperature of the brake disc (BD) rises above a preset temperature, the control unit (500) controls the operation of the driving unit (400) to place the guide unit (300) at the second position, thereby exposing the caliper unit (100) to the outside.

[0121] This allows wind (W) to flow into the interior of the caliper part (100), so that the caliper part (100) or brake disc (BD) can be effectively cooled by the wind (W).

[0122] That is, the control unit (500) obtains vehicle information from the sensor unit (600) and moves the guide unit (300) to an appropriate position on the brake disc (BD), thereby having the effect of adjusting the particle (P) collection efficiency and the brake disc (BD) cooling efficiency according to the driving conditions of the vehicle.

[0123] Referring to FIG. 6, a sensor unit (600) according to one embodiment of the present invention can obtain vehicle speed information, brake disc (BD) rotation speed information, brake disc (BD) temperature information, information on the amount of generated particles (P), information on the charge amount of particles (P), etc. and transmit the information to the control unit (500).

[0124] This makes it possible for the control unit (500) to appropriately adjust the position of the guide unit (300) according to vehicle operation information, external environment information, etc.

[0125]

[0126] Hereinafter, an electric dust collector (1`) according to another embodiment of the present invention will be described.

[0127] An electric dust collector (1`) according to another embodiment of the present invention has the same configuration and operating principle as the electric dust collector (1) according to one embodiment of the present invention, except that the cover part (250`) of the dust collector (200`) can move along the circumferential direction of the brake disc (BD), so a detailed description is omitted to the extent that it overlaps therewith.

[0128] FIG. 7 is a schematic drawing of a caliper-type electric precipitator according to another embodiment of the present invention, and FIG. 8 is a drawing for illustrating a state of use of a caliper-type electric precipitator according to another embodiment of the present invention.

[0129] A dust collecting unit (200`) of an electric dust collector (1`) according to another embodiment of the present invention may include a first dust collecting plate (210`) to which a high voltage is applied, a second dust collecting plate (220`) that is spaced apart from the first dust collecting plate (210`) and grounded, and a cover unit (250`) that accommodates the first dust collecting plate (210`) and the second dust collecting plate (220`) inside and is movable along the circumferential direction of a brake disc (BD).

[0130] Referring to FIG. 7 and FIG. 8, the cover part (250`) can accommodate a first dust collecting plate (210`) and a second dust collecting plate (220`) inside, and can be formed to extend along the circumferential direction of the brake disc (BD).

[0131] The length of the cover part (250`) extending along the circumferential direction of the brake disc (BD) can be formed to be relatively longer than the length of the first dust collecting plate (210`) and the second dust collecting plate (220`) extending along the circumferential direction of the brake disc (BD).

[0132] In addition, the length of the cover portion (250`) extending along the circumferential direction of the brake disc (BD) may be formed to be 60% or more and less than 100% of the sum of the lengths of the first dust collecting plate (210`) and the second dust collecting plate (220`) extending along the circumferential direction of the brake disc (BD) and the length of the caliper portion (100) extending along the circumferential direction of the brake disc (BD).

[0133] As a result, the cover part (250`) can cover the first dust collecting plate (210`) and the second dust collecting plate (220`) while simultaneously covering one side of the caliper part (100), so that the cover part (250`) can guide particles (P) generated on the caliper part (100) side to flow to the space between the first dust collecting plate (210`) and the second dust collecting plate (220`).

[0134] Referring to FIG. 7 and FIG. 8, the cover part (250`) can selectively cover the caliper part (100) as it moves toward the caliper part (100).

[0135] In the following specification, the 'third position' may be interpreted as the position of the cover portion (250`) arranged to cover the caliper portion (100), and the 'fourth position' may be interpreted as the position of the cover portion (250`) arranged to expose the caliper portion (100) to the outside.

[0136] However, it is not limited thereto, and the 'third position' can be interpreted as the position of the cover part (250`) arranged to cover a preset area of ​​the caliper part (100), and the 'fourth position' can be interpreted as the position of the cover part (250`) arranged to cover a relatively narrower area than the above-described area of ​​the caliper part (100).

[0137] For example, when the cover part (250`) moves to the third position, the cover part (250`) can cover more than half of the outer surface of the caliper part (100), and when the cover part (250`) moves to the fourth position, the cover part (250`) can cover less than half of the outer surface of the caliper part (100).

[0138] The cover part (250`) can be moved along the circumferential direction of the brake disc (BD).

[0139] The cover part (250`) can receive an electric signal from the control part (500`) and move along the circumferential direction of the brake disc (BD).

[0140] Specifically, the cover part (250`) can receive power from the driving part (400`) and move along the circumferential direction of the brake disc (BD), and the driving part (400`) can receive an electric signal from the control part (500`) and adjust the position of the cover part (250`).

[0141] Referring to FIG. 8, the cover part (250`) can selectively accommodate the caliper part (100) according to an electrical signal from the control part (500`).

[0142] The width in the thickness direction of the brake disc (BD) of the cover part (250`) may be relatively larger than the width in the thickness direction of the brake disc (BD) of the caliper part (100).

[0143] The cover part (250`) can move along the circumferential direction of the brake disc (BD), and the outer surface of the caliper part (100) can be covered by moving the cover part (250`) to the third position, and the outer surface of the caliper part (100) can be exposed to the outside by moving the cover part (250`) to the fourth position.

[0144] Referring to Fig. 8, the cover part (250`) receives power from the driving part (400`) and moves to the third position, thereby covering the outer surface of the caliper part (100).

[0145] As a result, the cover part (250`) partitions the caliper part (100) from the external space, thereby restricting the wind (W) directed toward the caliper part (100) due to the vehicle driving, etc. from flowing into the inside of the caliper part (100), thereby guiding the movement path of the particles (P) generated inside the caliper part (100) so that they flow toward the dust collection part (200`) without being affected by the wind (W), etc.

[0146] Referring to Fig. 7, the cover part (250`) receives power from the driving part (400`) and moves to the fourth position, so that the caliper part (100) can be exposed to the outside.

[0147] As a result, the wind (W) flows into the internal space of the caliper part (100) or the space between the caliper part (100) and the dust collector (200`), thereby improving the contact area between the wind (W) and the brake disc (BD), thereby increasing the cooling efficiency of the brake disc (BD).

[0148] In an optional embodiment, a plurality of cover parts (250`) may be provided, and the plurality of cover parts (250`) may each receive power from the driving part (400`) and move independently along the circumferential direction of the brake disc (BD).

[0149] The position of the cover part (250`) can be adjusted depending on the rotation speed of the brake disc (BD), the temperature of the brake disc (BD), the amount of particles (P) generated, or the amount of charge of the particles (P), and a detailed description thereof will be provided later.

[0150] In an optional embodiment, the cover part (250`) may be movably connected to one side of the caliper part (100). As a result, the cover part (250`) may move relative to the caliper part (100) fixed to the brake disc (BD), thereby selectively covering or exposing the caliper part (100) to the outside.

[0151] In an optional embodiment, the cover portion (250`) may be movably connected to one side of the brake disc (BD). As a result, the cover portion (250`) may move relative to the brake disc (BD), thereby selectively covering or exposing to the outside the caliper portion (100) fixed to the brake disc (BD).

[0152] The cover part (250`) may be formed of a material with high heat dissipation performance and high thermal conductivity. Accordingly, even if the cover part (250`) is positioned at the third position to cover the caliper part (100), the heat generated in the caliper part (100) is allowed to be dissipated to the outside, so that the cover part (250`) can guide the movement path of the particles (P) while ensuring cooling efficiency of the brake disc (BD).

[0153] The control unit (500`) can adjust the position of the cover unit (250`) on the brake disc (BD), and the control unit (500`) can adjust the position of the cover unit (250`) by controlling the operation of the driving unit (400`) that provides power to the cover unit (250`).

[0154] The control unit (500`) can obtain at least one of the vehicle speed information, the rotation speed information of the brake disc (BD), the temperature information of the brake disc (BD), the information on the amount of particles (P) generated, or the information on the charge amount of the particles (P) from the sensor unit (600) to be described later, and can adjust the position of the cover unit (250`) using the obtained information.

[0155] Referring to FIG. 8, the control unit (500`) can control the operation of the driving unit (400`) to place the cover unit (250`) at the third position so that the cover unit (250`) covers the caliper unit (100).

[0156] When the vehicle speed is high or the brake disc (BD) rotates at high speed, the control unit (500`) can control the operation of the driving unit (400`) to place the cover unit (250`) in the third position so that the cover unit (250`) covers the caliper unit (100).

[0157] As a result, the wind (W) is restricted from flowing inside the caliper section (100), thereby preventing the wind (W) from flowing toward the dust collecting section (200`) and being blown outward, thereby increasing the particle (P) collection efficiency.

[0158] When the amount of particles (P) generated between the brake disc (BD) and the caliper part (100) is large, the control part (500`) can control the operation of the driving part (400`) to place the cover part (250`) in the third position so that the cover part (250`) covers the caliper part (100).

[0159] When the charge of the particle (P) is low, the control unit (500`) can control the operation of the driving unit (400`) to place the cover unit (250`) at the third position so that the cover unit (250`) covers the caliper unit (100).

[0160] Due to this, even if the charge of the particles (P) is low, the cover part (250`) guides a large amount of particles (P) to flow toward the dust collecting part (200`), thereby increasing the amount of particles (P) captured in the dust collecting part (200`).

[0161] Referring to FIG. 7, the control unit (500`) can control the operation of the driving unit (400`) to place the cover unit (250`) at the fourth position so that the caliper unit (100) is exposed to the outside.

[0162] When the temperature of the brake disc (BD) rises above a preset temperature, the control unit (500`) controls the operation of the driving unit (400`) to place the cover unit (250`) at the fourth position, thereby exposing the caliper unit (100) to the outside.

[0163] This allows wind (W) to flow into the interior of the caliper part (100), so that the caliper part (100) or brake disc (BD) can be effectively cooled by the wind (W).

[0164] That is, the control unit (500`) obtains vehicle information from the sensor unit (600) and moves the cover unit (250`) to an appropriate position on the brake disc (BD), thereby having the effect of adjusting the particle (P) collection efficiency and the brake disc (BD) cooling efficiency according to the driving conditions of the vehicle.
