Description

Technical Field

[0001] This utility model relates to the field of brake caliper technology, specifically to a high-sealing integrated brake caliper assembly. Background Technology

[0002] Brake calipers are automotive components used to brake the wheels. They are hydraulically controlled and mainly consist of brake discs, calipers, brake pads, and brake lines. The brake discs are made of alloy steel and are fixed to the wheel. As the wheel rotates, braking force is generated by the brake pads on the brake calipers clamping the brake discs. An integrated brake caliper assembly is a component of an automotive braking system, typically used in disc brake systems. It integrates the brake caliper with other related components (such as brake pads and pistons) into a single structure.

[0003] During use, insufficient sealing of brake calipers may lead to hydraulic oil leakage, thereby reducing the pressure of the braking system, affecting braking performance, increasing braking distance, and even causing brake failure. External contaminants (such as moisture and dust) entering the brake caliper will accelerate the wear of pistons and seals, shortening their service life. If the seal is poor, gas or liquid in the braking system may not be able to escape effectively, causing the heat generated during braking to not be dissipated in time, which will lead to brake fade and affect braking stability. Hydraulic oil leakage or the entry of external moisture may cause rust or corrosion inside the brake caliper, further damaging the structural integrity of the braking system.

[0004] To address this, a high-sealing integrated brake caliper assembly is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a high-sealing integrated brake caliper assembly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing integrated brake caliper assembly, comprising two brake caliper bodies, with hydraulic cylinders fixedly connected to the middle of both sides of each brake caliper body, a first spring sleeved on the middle of the outer wall of each hydraulic cylinder, friction pads slidably connected to both ends of the outer wall of each hydraulic cylinder, the two ends of the first springs being fixedly connected to the friction pads on both sides respectively, a first guide rod provided at the middle of both sides of each brake caliper body, a pair of second guide rods provided at the middle of the upper part of each brake caliper body, a branch pipe fixedly connected to the top of each brake caliper body, and an oil pipe fixedly connected to the top of the branch pipes on both sides.

[0007] Preferably, the inner walls of the friction pads on both sides are provided with brake discs.

[0008] Preferably, pistons are provided on both sides of the inner wall of the brake caliper.

[0009] Preferably, a sealing ring is fixedly connected to the inner wall of the brake caliper body located on the outer wall of the piston, and a plurality of second springs are fixedly connected to the inner wall of the sealing ring.

[0010] Preferably, an outer ring is fixedly connected to one end of the second spring, and the inner wall of the outer ring is attached to the outer wall of the piston.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting a sealing ring structure in the middle of the brake caliper body to protect the piston, the sealing ring can effectively prevent hydraulic oil from leaking from the contact surface between the piston and the cylinder, ensuring stable pressure in the braking system, thereby improving braking performance. It can also prevent dust, moisture and other contaminants from entering the brake caliper, reducing wear on the piston and other internal components and extending their service life. Good sealing performance can ensure that the piston moves quickly and accurately during braking, improving the response speed and sensitivity of the braking system. By preventing hydraulic oil leakage and the intrusion of external contaminants, it can reduce wear on the braking system, reduce the failure rate, thereby reducing the frequency of maintenance and replacement of parts and reducing long-term operating costs.

[0013] 2. By setting guide rods at the middle of both ends of the brake caliper body for limiting movement, the guide rods can effectively guide the movement of the piston, ensuring that the piston maintains the correct position and direction during operation, thereby improving the overall accuracy of the braking system and providing stable guidance. The guide rods can reduce friction and wear between the piston and other internal components of the brake caliper, extending the service life of the components. They also restrict the free movement of the piston, preventing it from deviating or wobbling during braking, thus improving the stability and consistency of braking. The design of the guide rods can also help disperse the heat generated during braking, reducing the risk of local overheating and maintaining stable braking performance. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 The present invention provides an embodiment of a high-sealing integrated brake caliper assembly, comprising two brake caliper bodies 1, with hydraulic cylinders 2 fixedly connected to the middle of both sides of the brake caliper bodies 1, a first spring 3 sleeved on the middle of the outer wall of both sides of the hydraulic cylinders 2, friction plates 4 slidably connected to both ends of the outer wall of both sides of the hydraulic cylinders 2, the two ends of the first spring 3 being fixedly connected to the friction plates 4 on both sides respectively, a first guide rod 5 provided on the middle of both sides of the brake caliper bodies 1, a pair of second guide rods 6 provided on the middle of the upper part of both sides of the brake caliper bodies 1, a branch pipe 8 fixedly connected to the top of both sides of the brake caliper bodies 1, and an oil pipe 7 fixedly connected to the top of the branch pipe 8 on both sides.

[0023] Wherein: the interior of the brake caliper 1 is hollow, and both ends of the branch pipe 8 penetrate into the interior of the brake caliper 1, so that the lubricating oil can flow from the inside;

[0024] Even better: Through the operation of the hydraulic cylinders 2 on both sides, and with the buffer and limiting cooperation of the first springs 3 on both sides, the friction pads 4 on both sides can make more stable clamping contact with the brake disc 9 during the movement and adjustment process. The setting of the first guide rod 5 and the second guide rod 6 can provide limiting and guiding assistance for the brake caliper 1, making the operation of the brake caliper 1 more stable and preventing directional deviation. A certain amount of lubricating oil is injected through the oil pipe 7, and with the cooperation of the branch pipes 8 on both sides, the oil is transported to the interior of the brake caliper 1 on both sides, and finally flows into the inner wall of the pistons 10 on both sides.

[0025] Brake discs 9 are provided on the inner walls of the friction pads 4 on both sides. Pistons 10 are provided on both sides of the inner walls of the brake calipers 1 on both sides. A sealing ring 11 is fixedly connected to the inner wall of the brake caliper 1 on the outer wall of the piston 10. Several second springs 12 are fixedly connected around the inner wall of the sealing ring 11. An outer ring 13 is fixedly connected to one end of the second spring 12 that is close to each other. The inner wall of the outer ring 13 is attached to the outer wall of the piston 10.

[0026] Among them, the sealing ring 11 is made of soft rubber;

[0027] Even better: With the installation and use of the piston 10, the sealing ring 11 can be attached to and squeezed by the second spring 12 according to its outer diameter size, so that the sealing ring 11 can be tightly fitted on the outer wall of the piston 10, ensuring the sealing performance of the piston 10 during use.

[0028] The working principle of the above implementation is as follows:

[0029] The operation steps are as follows:

[0030] First, through the operation of the hydraulic cylinders 2 on both sides, and with the buffering and limiting cooperation of the first springs 3 on both sides, the friction pads 4 on both sides can make more stable clamping contact with the brake disc 9 during the movement and adjustment process. The setting of the first guide rod 5 and the second guide rod 6 can provide limiting and guiding assistance for the brake caliper body 1, making the operation of the brake caliper body 1 more stable and preventing directional deviation. A certain amount of lubricating oil is injected through the oil pipe 7, and with the cooperation of the branch pipes 8 on both sides, the oil is delivered to the interior of the brake caliper body 1 on both sides, and finally flows into the inner wall of the pistons 10 on both sides, effectively preventing hydraulic oil from leaking from the contact surface between the piston 10 and the cylinder body, ensuring the pressure stability of the braking system, thereby improving braking performance. It can also prevent dust, moisture and other contaminants from entering the interior of the brake caliper, reduce the wear of the piston 10 and other internal components, and extend their service life.

[0031] Good sealing performance ensures that the piston 10 moves quickly and accurately during braking, improving the response speed and sensitivity of the braking system. By preventing hydraulic oil leakage and the intrusion of external contaminants, wear on the braking system can be reduced, the failure rate can be lowered, thereby reducing the frequency of maintenance and replacement of parts and reducing long-term operating costs. With the installation and use of the piston 10, the sealing ring 11 can be attached to the second spring 12 according to its outer diameter size, so that the sealing ring 11 can be tightly fitted on the outer wall of the piston 10, ensuring the sealing performance of the piston 10 during use.
