Description

caliper-type dust collecting apparatus Embodiments of the present invention relate to a caliper-type particle dust collector. It is generally known that fine dust generated during vehicle operation is produced in large quantities by tire and brake pad wear in addition to exhaust gases; therefore, to reduce urban fine dust, it is required to reduce fine dust generated by automobiles, which is one of the primary causes of mobile pollution. Specifically, the vehicle's braking system generates braking force through the frictional force produced by pressing brake pads against brake discs that rotate together with the vehicle's wheels; however, during vehicle braking, the wear of the brake pads caused by friction between the brake disc and the brake pads generates various types of dust harmful to the human body. Fine dust generated by brake pad wear is known to have harmful effects on the human body, including respiratory, eye, and skin diseases, due to its very small size and toxic composition. Therefore, the development of technology to address this issue is required. While the impact of fine dust generation from exhaust gases is expected to gradually decrease due to the recent increase in hydrogen and electric vehicles, fine dust generation caused by tire and brake pad wear still occurs because these vehicles utilize braking systems similar to internal combustion engine vehicles. Devices installed around automobile wheels to capture fine dust generated by tire and brake pad wear have been developed, and most of them use a filter method. However, in the case of filter-type air purifiers, pressure loss caused by the filter makes it difficult for air containing particles to enter, resulting in practical difficulties in capturing fine dust after a certain period of time. Additionally, fiber filters have limitations in maintenance, such as the difficulty of cleaning and regenerating them, which necessitates frequent replacement.
