Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and relates to a brake caliper, particularly a ball-expanding plug-type brake caliper with tight impact resistance. Background Technology

[0002] The brake caliper is the core component of a disc brake, which achieves braking by hydraulically pushing a piston to clamp the brake disc. It is mainly divided into two types: floating caliper (single / double piston, low cost) and fixed caliper (multiple pistons, uniform braking force). Materials include aluminum alloy and titanium alloy. Its functions include deceleration braking, heat dissipation, and supporting safety functions such as ABS. Currently, most modern vehicles use floating caliper disc brakes.

[0003] Existing brake calipers use aluminum plugs for the small holes on the outside of the vent, which are prone to cracking and leaking air during high-pressure testing due to excessive pressure, preventing normal vehicle installation. To solve this technical problem, we have designed a ball-expansion plug-type brake caliper that is airtight and impact-resistant. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a ball-expanding plug-type brake caliper that is tight and impact-resistant.

[0005] The purpose of this utility model can be achieved through the following technical solution: a ball-expanding plug-type tight impact-resistant brake caliper, including a caliper body, wherein air vents are provided on the top of both the front and rear sides of the caliper body, a flow hole is provided at the bottom of the inner wall of the air vent, and a ball-expanding plug is installed on one side of the inner wall of the flow hole.

[0006] This ball-expansion plug is a tightly sealed and impact-resistant brake caliper. The ball-expansion plug offers high strength and is made of stainless steel with a one-piece structure, effectively ensuring a tight seal. It also has strong impact resistance, preventing material rupture and air leakage during high-pressure testing, thus improving its pass rate for normal vehicle installation.

[0007] In the aforementioned ball-expansion plug-type tight-fitting impact-resistant brake caliper, mounting brackets are connected to the top of both the left and right sides of the caliper body. The top of each mounting bracket has a through-hole, and the mounting bracket is integrally formed with the caliper body. The mounting bracket and the mounting hole facilitate the positioning and installation of the caliper body.

[0008] In the aforementioned ball-expansion plug-type tight-fitting impact-resistant brake caliper, the vent hole is a threaded hole, one side of the inner wall of the flow hole penetrates the caliper body, and the ball-expansion plug is made of stainless steel. The stainless steel material of the ball-expansion plug provides it with strong impact resistance.

[0009] In the aforementioned ball-expansion plug-type tight-fitting impact-resistant brake caliper, a filter component is installed inside the vent hole. This filter component includes a threaded ring, the outer side of which is threadedly connected to the inner wall of the vent hole. Insertion holes are provided on both the left and right sides of the top of the threaded ring. These insertion holes facilitate the insertion of external rods into the threaded ring, enabling subsequent rotation of the threaded ring and thus completing its disassembly and installation.

[0010] In the aforementioned ball-expansion plug-type tight-fitting impact-resistant brake caliper, a support ring is connected to the bottom of the inner wall of the threaded ring. Several connecting screw holes are formed through the top of the support ring. A filter ring is placed on the top of the support ring, and several positioning bolts are provided on the top of the filter ring. The bottom of each positioning bolt passes through the filter ring and is threadedly connected to the connecting screw holes. The positioning bolts facilitate the positioning and installation of the filter ring on the support ring.

[0011] Compared with existing technologies, this ball-expansion plug provides a tight and impact-resistant brake caliper. The use of the ball-expansion plug offers advantages such as high strength. The ball-expansion plug is made of stainless steel and has an integrated structure that effectively ensures sealing. The ball-expansion plug has strong impact resistance and will not cause material rupture due to excessive pressure during high-pressure testing, thus improving the pass rate of normal vehicle assembly.
