UTILITY MODEL CONTENTS

[0004] The utility model aims at providing an electromechanical integrated caliper with bent oil passage, which reduces the number of oil passages, realizes the connection of the two brake oil cylinders on the same side of the caliper through the single oil passage, reduces the production difficulty of the caliper, retains more materials in the caliper, and is higher in strength and longer in service life.

[0005] In order to solve the above technical problems, the utility model adopts the following scheme:

[0006] An electromechanical integrated caliper with bent oil passage, comprising a caliper body, characterized by comprising:

[0007] The caliper body is provided with an oil inlet, the center of the caliper body has a space for arranging brake pads, and the brake pads are located on the both sides of the automobile brake disc.

[0010] In the scheme, the caliper body serves as the support frame of the entire brake system, which is designed to be firm and compact to meet the high-strength use requirements of the automobile. The oil inlet is ingeniously arranged on the caliper body, which is the entrance of the brake fluid in the hydraulic brake system and is used to provide the necessary pressure to the inside of the caliper body. The center of the caliper body is reserved with sufficient space for installing brake pads, which are located on both sides of the brake disc of the automobile and are the key components for actually generating friction and slowing down the rotation of the wheels. The brake pistons are designed to be installed on both sides of the inside of the caliper body in a telescopic manner. This design allows the pistons to move smoothly along the axial direction of the oil cylinder inside the caliper body under the pressure of the brake fluid. When the pistons are pushed by the brake fluid, they will extend towards the brake disc, thereby pressing the brake pads on both sides of the brake disc and achieving the brake function. The oil channels serve as the passage for the transmission of brake fluid and are closely connected with the oil inlet to ensure that the brake fluid can smoothly enter the inside of the caliper body. One end of the oil channels extends to one side of the inside of the caliper body for connecting the brake pistons on that side, and the other end of the oil channels extends to the other side of the caliper body for connecting the brake pistons on that side. This ensures that the brake fluid can simultaneously and uniformly act on the brake pistons on both sides. The brake pistons on the same side of the caliper body are connected only through one oil channel. Compared with the existing caliper with a double-oil-channel design, the present scheme reduces the number of oil channels, thereby reducing the production difficulty of the caliper. The reduction in the number of oil channels allows more material to be reserved inside the caliper, thereby improving the strength of the caliper and prolonging the service life of the caliper. Furthermore, the reduction in the number of oil channels allows the volume of air remaining in the caliper to be smaller during the air-bleeding operation of the caliper, thereby allowing the caliper to respond faster and achieve better braking effect.

[0030] EMBODIMENT

[0031] An electromechanical caliper with a curved oil passage, comprising a caliper body 1, characterized by comprising:

[0032] The caliper body 1 is provided with an oil inlet 4, and the center of the caliper body 1 has a space for setting brake pads, and the brake pads are located on both sides of the automobile brake disc;

[0033] The brake piston is installed on both sides of the caliper body 1 in a telescopic manner for pushing the brake pad to be pressed on the brake disc;

[0034] The oil channel is connected to the oil inlet 4, one end of the oil channel extends to the inside of the caliper body 1 for connecting to the brake piston on one side of the caliper body 1, and the other end extends to the other side of the caliper body 1 to connect to the brake piston on the other side of the caliper body 1. The brake pistons on the same side of the caliper body 1 are connected through only one oil channel.

[0035] In this embodiment, Figure 1 and Figure 2 As shown, the caliper body 1 serves as the support framework for the entire brake system. Its design is sturdy and compact to accommodate the intensive use demands of a vehicle. The caliper body 1 consists of an inner caliper and an outer caliper, which are located on either side of the brake disc. An oil inlet 4 is strategically positioned on the caliper body 1. This is the entrance for the brake fluid in the hydraulic brake system, providing the necessary pressure to the caliper. Sufficient space is reserved in the center of the caliper body 1 for the brake pads, which are located on either side of the vehicle's brake disc and are the key components that actually generate friction and slow the wheel's rotation. The brake pistons are designed to be retractably mounted on either side of the caliper body 1. This design allows the pistons to move smoothly along the caliper's internal track under the pressure of the brake fluid. The brake disc and brake pads are not shown in the figure. When the pistons are pushed by the brake fluid, they extend toward the brake disc, thereby compressing the brake pads on either side of the disc and achieving the braking function. The oil channel, which serves as a channel for the brake fluid, is closely connected to the oil inlet 4, ensuring smooth entry of the brake fluid into the caliper. One end of the oil channel extends to one side of the inside of the caliper body 1, and is used to connect to the brake piston on this side; the other end extends to the other side of the caliper body 1, and is connected to the brake piston on the other side. This ensures that the brake fluid can act on the brake pistons on both sides simultaneously and evenly. The brake pistons on the same side of the caliper body 1 are connected through only one oil channel. Compared with the dual oil channel design used in existing calipers, this method reduces the number of oil channels, and the difficulty of producing the caliper is also reduced. The reduction in the number of oil channels allows more material to be retained inside the caliper, thereby increasing the strength of the caliper and extending the service life of the caliper. Furthermore, the reduction in the number of oil channels reduces the volume of air remaining in the caliper during the air exhaust operation when the caliper is loaded on the vehicle, resulting in a faster response to the caliper and a better braking effect.

[0036] Furthermore, two brake pistons are provided on the same side of the caliper body 1, and the brake piston is the first piston 3. A first oil cylinder 11 for installing the first piston 3 is formed in the caliper body 1, and a second oil cylinder 12 is provided between the two first oil cylinders 11 on the same side. A retractable second piston 6 is installed in the second oil cylinder 12, and the second piston 6 is a parking piston. A transition oil channel 13 formed by the caliper body 1 is provided below the parking piston. The transition oil channel 13 is part of the oil channel and simultaneously connects the two first pistons 3 on the same side of the caliper body 1.

[0037] Specifically, such as Figure 1 andFigure 2 As shown, the caliper body 1 is provided with two brake pistons (first pistons 3) on the same side, the two pistons are respectively installed in two independent first oil cylinders 11, the first pistons 3 are key components telescopically installed in the first oil cylinders 11, used to push the brake pads to compress the brake disc under the action of brake fluid, the first oil cylinders 11 are sealed spaces provided in the caliper body 1 for the first pistons 3, to ensure that the brake fluid can exert stable pressure. The second piston 6 (parking piston) is installed in the second oil cylinder 12, used to realize the parking (hand brake) function. When the parking piston is extended, it will lock the brake system by mechanical or hydraulic way, to prevent the vehicle from moving, the second oil cylinder 12 is a sealed space provided in the caliper body 1 for the parking piston, to ensure the reliability and stability of the parking function, the brake pistons, the first oil cylinders 11, the parking piston, and the second oil cylinder 12 all belong to the prior art.

[0038] The transition oil passage 13 is a part of the oil passage, composed of the caliper body 1, which simultaneously connects the two first pistons 3 on the same side of the caliper body 1, so that the brake fluid can flow between the two first oil cylinders 11, without the need to open another flow passage, i.e. the long flow passage of the existing product, more material is reserved in the caliper, the strength of the caliper is higher, and the production difficulty of the caliper is also reduced.

[0039] Further, the oil passage includes a first oil passage 8 and a second oil passage 10, the first oil passage 8 is distributed on both sides of the caliper body 1, the first oil passage 8 simultaneously communicates the two first oil cylinders 11 on the same side of the caliper body 1, the second oil passage 10 is distributed at one end of the caliper body 1, the two ends of the second oil passage 10 are respectively connected with the first oil passage 8 on both sides of the caliper body 1, the transition oil passage 13 is arranged at the middle position of the first oil passage 8, and the end of the first oil passage 8 is formed with a sealable opening.

[0040] Further, the caliper body 1 is provided with a semicircular groove located directly below the parking piston, and the semicircular groove and the outer wall of the parking piston form the transition oil passage 13.

[0041] Specifically, the first oil channel 8 is distributed on both sides of the caliper body 1, ensuring that the brake fluid can be uniformly transmitted to the two first oil cylinders 11 on the same side. The first oil channel 8 simultaneously communicates the two first oil cylinders 11 on the same side of the caliper body 1, which means that when the brake fluid enters the first oil channel 8, it can simultaneously act on the first pistons 3 in the two oil cylinders, achieving more uniform brake force distribution. The end of the first oil channel 8 forms an opening that can be sealed. The second oil channel 10 is distributed at one end of the caliper body 1 and serves to connect the first oil channels 8 located on both sides of the brake disc. The two ends of the second oil channel 10 are connected to the first oil channels 8 on both sides of the caliper body 1, forming a complete brake fluid transmission loop. This design allows the brake fluid to circulate within the caliper body 1, ensuring the response speed and consistency of the brake system. The transition oil channel 13 is provided at the middle position of the first oil channel 8 and is formed between the semicircular groove on the caliper body 1 directly below the parking piston and the outer wall of the parking piston. It is semicircular in shape and can also be referred to as a curved oil channel. This design cleverly utilizes the structural space of the caliper body 1. The first flow channel is divided into multiple sections and is distributed on the same horizontal plane. There is a first flow channel on the left and right sides of the brake piston. The transition oil channel 13 connects the first flow channels on both sides of the parking piston. The transition oil channel 13 and the multiple first oil channels 8 together form an oil channel. Thus, the two brake pistons are connected through only one oil channel, thereby reducing the number of oil channels and the difficulty of caliper production. The reduction in the number of oil channels allows more material to be retained within the caliper, improving the strength of the caliper and extending its service life.

[0042] Further, oil channel sealing rings 5 are provided on both sides of the semicircular groove, and the oil channel sealing rings 5 are distributed along the axial direction of the second piston 6.

[0043] Specifically, the oil channel sealing rings 5 are installed on both sides of the semicircular groove, which is a key part of the transition oil channel 13. The oil channel sealing rings 5 are distributed along the axial direction of the second piston 6 to prevent brake fluid from leaking from the transition oil channel 13. In addition to preventing leakage, the oil channel sealing rings 5 can effectively prevent external impurities and moisture from entering the brake system, thereby protecting the system from contamination and damage.

[0044] Further, a gas release valve 9 is connected to the opening at the end of the first oil channel 8. Specifically, the gas release valve 9 can be used to discharge air from the oil channel. The reduction in the number of oil channels results in a smaller volume of air remaining in the caliper during the air discharge operation after the caliper is installed on the vehicle. The caliper responds faster and provides better braking effect.

[0045] Further, the oil inlet 4 corresponds to the first oil cylinder 11, and a plug screw 7 can be connected to the oil inlet 4.

[0046] Further, the oil inlet 4 is provided with two, two oil inlets 4 are distributed on both sides of the second oil cylinder 12, one of which is connected with the plug screw one 7, and the other is used for brake fluid into the first oil channel 8.

[0047] Specifically, the oil inlet 4 is provided on the first oil channel 8, and the oil inlet 4 is provided with two, two oil inlets 4 correspond to the first oil cylinder 8 on both sides of the second oil cylinder 12, wherein the left oil inlet 4 is connected with the plug screw one 7, and the right oil inlet 4 is connected with the oil pipe, which is used for conveying brake fluid into the first oil channel 8. According to the installation position of the motor, any one of the oil inlets 4 on both sides of the second oil cylinder 12 can be selected as the inlet of the brake fluid, and the other one can be plugged with the plug screw one 7, which is convenient for the installation and selection of the motor position.

[0048] Further, the first oil channel 8 and the second oil channel 10 are connected at the position provided with the extension oil channel 19, and the extension oil channel 19 is connected with the plug screw two 2.

[0049] Further, the second oil channel 10 is inclined upward, which is a inclined oil channel.

The inclined oil channel replaces the external oil pipe 16 connected with the first oil channel 8, and the external oil pipe 16 is easy to be damaged.

[0050] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. According to the technical essence of the present application, any simple modification, equivalent replacement and improvement of the above embodiment within the spirit and principles of the present application are still within the protection scope of the present application.
