Description

Technical Field

[0001] This utility model relates to the field of automotive brake caliper technology, specifically an automotive brake caliper with a friction pad dust collection device. Background Technology

[0002] The EU's new R90 regulation imposes strict restrictions on brake pad formulations, requiring a reduction in harmful metal components to lower dust pollution levels, thus driving the industry to develop efficient dust collection technologies. Chinese companies have already begun researching brake dust collection devices, achieving dust capture through graded filtration and intelligent control systems. The Chinese automotive friction pad market is projected to reach 6.574 billion yuan by 2025. Driven by remanufacturing policies, dust control technologies will develop towards higher efficiency, lower energy consumption, and greater intelligence. For example, patent CN112969864B discloses a system for extracting brake particles from a friction braking system. The extraction system includes a negative pressure source, a suction nozzle, a pneumatic circuit (3, 3', 30) connecting the suction nozzle and the negative pressure source, and a control unit. The extraction system also includes a shut-off member disposed on the pneumatic circuit, the shut-off member being capable of isolating at least a first portion of the pneumatic circuit. The control unit is configured to control the shut-off member according to predetermined logic to isolate the first portion of the pneumatic circuit during a specific phase between two actual uses of the negative pressure source. However, the invention has a relatively complex structure, requires a suction system, occupies a large space, and has high maintenance and production costs. Utility Model Content

[0012] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0013] Please see Figures 1-5 This utility model provides a technical solution: an automotive brake caliper with a friction pad dust collection device, comprising a bracket 1, a brake disc 3, and a brake caliper body 2 fixed on the bracket 1, and further comprising: The outer casing 4 is fixed on the bracket 1. With the rotation direction of the brake disc 3 as the reference, the outer casing 4 is located downstream of the brake caliper 2. An opening 4.1 is provided at the center of the outer casing 4, and the brake disc 3 is placed in the opening 4.1. Collection box 5, there is a pair of collection boxes 5, which are mirror images of each other inside the opening 4.1 and are fixedly connected to the outer shell 4. The collection box 5 collects the powder generated on both sides of the brake disc 3. The collection box 5 is volute-shaped and has a collection port 5.1. When the brake caliper generates powder, the powder can enter the outer shell 4 and enter the collection box 5 through the collection port 5.1. An airflow hole 6 is provided on one side wall of the collection box 5 to balance the air pressure inside the collection box 5.

[0014] As an embodiment of this utility model, a storage groove 5.2 is provided at the center of the collection box 5. After the friction plate dust rotates once inside the collection box 5, it can enter the storage groove 5.2, thus preventing the dust from easily flowing out of the collection box 5.

[0015] As an embodiment of this utility model, an ear plate 4.2 is fixedly provided on the outer shell 4. The ear plate 4.2 can be fixedly connected to the bracket 1 using screws. The outer shell 4 is composed of two half shells, which are fixedly connected by bolts to facilitate the disassembly of the outer shell 4.

[0016] As an embodiment of this utility model, the side surface of the collection box 5 and the brake disc 3 are fitted with a clearance to avoid friction between the collection box 5 and the brake disc 3.

[0017] The working principle and usage process of this utility model are as follows: Please refer to... Figure 5 When the brake caliper 2 generates friction pad dust, the dust enters the outer shell 4 under the action of inertia. Most of the dust can be collected through the collection port 5.1 inside the outer shell 4. After the dust enters the collection box 5, it rotates once and enters the storage tank 5.2 for storage. At the same time, the air pressure inside and outside the collection box 5 can be balanced through the airflow hole 6, which facilitates the dust to enter the collection box 5, thus realizing the collection of dust.

[0018] 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.
