[0032] Please see Figures 1-5 This utility model proposes a motorcycle caliper that is easy to install.

[0033] In one exemplary embodiment, the motorcycle caliper that is easy to install includes:

[0034] Left clamp body 1;

[0035] The right clamp body 8 is detachably connected to the left clamp body 1 via a connecting assembly. The right clamp body 8 has a left piston groove 5 inside and a mounting part 801 is provided on the right clamp body 8. At least a part of the left piston groove 5 is located in the mounting part 801.

[0036] At least one pair of vent holes 12 are provided on the mounting part 801. The vent holes 12 are connected to the left piston groove 5. The vent holes 12 are located on opposite sides of the mounting part 801. The mounting part 801 is provided with an oil drain connector 13 that can move axially along the vent holes 12.

[0037] In this embodiment, the design of detachable left and right clamp body structure and movable oil drain connector 13, along with multiple exhaust holes 12 provided on the mounting part 801 of the right clamp body 8, facilitates connection to the motorcycle's wiring from multiple angles. This solves the problem of limited installation space and difficult maintenance of traditional calipers due to exhaust components, and has the advantages of convenient installation, simple maintenance, and strong adaptability.

[0038] For example, the mounting part 801 can be designed as a boss structure integrally formed on the side wall of the right clamp body 8, with its internal cavity communicating with the left piston groove 5. Exhaust holes 12 are symmetrically distributed on both sides of the boss structure of the mounting part 801, and can be, for example, circular holes with a diameter of 3-5 mm, with their axes collinear or parallel. The oil drain connector 13 can be threaded, allowing axial movement through rotation. In a specific embodiment, a sealing ring can be provided at the front end of the oil drain connector 13, achieving a sealing effect when moved to the closed position.

[0039] It is worth noting that in this embodiment, the exhaust ports 12 are located on opposite sides of the mounting portion 801, improving installation flexibility and allowing the caliper to be installed upright or rotated at a certain angle before being installed with the motorcycle wiring, which is especially suitable for motorcycle models with limited installation space. By optimizing the structural layout, convenient installation is achieved while ensuring braking performance.

[0040] In an exemplary embodiment, the oil drain connector 13 has a connecting portion 1301 and a mating portion 1302. The connecting portion 1301 is used to connect with the vent hole 12, and an oil passage gap 14 is formed between the mating portion 1302 and the vent hole 12. The oil drain connector 13 is provided with an oil drain channel communicating with the oil passage gap 14.

[0041] In this embodiment, the oil drain connector 13 is mechanically fixed to the mounting part 801 via the connecting part 1301, and the mating part 1302 forms a precisely controlled oil passage gap 14 with the vent hole 12, establishing a complete oil discharge path through the oil drain channel. Specifically, the connecting part 1301 ensures installation reliability, the mating part 1302 and the vent groove form a stable gap through a hole-shaft fit, and the oil drain channel directionally discharges the oil at the gap. This solves the technical problem of forming a stable oil passage gap 14 between the oil drain connector 13 and the vent hole 12 and achieving connectivity of the oil drain channel. This embodiment achieves precise control of the oil draining process through structural optimization, avoiding oil leakage and structural loosening problems, while simplifying installation and maintenance operations.

[0042] For example, the connecting part 1301 can be fixed to the vent hole 12 by means of threaded connection, snap connection, or interference fit. The mating part 1302 can be designed as a cylindrical, conical, or stepped structure. The width of the oil passage gap 14 is controlled within the range of 0.1-0.5mm to ensure both oil flow and structural stability. The oil drain channel can be set as an L-shaped, T-shaped, or straight channel, and the channel diameter is preferably 2-4mm. As a preferred embodiment, an annular guide groove can be provided at the end of the mating part 1302 to improve the oil flow characteristics.

[0043] In an exemplary embodiment, the oil drain connector 13 has a sealing position abutting against the vent hole 12 and an oil drain position separated from the vent hole 12. When the oil drain connector 13 is in the sealing position, the oil passage gap 14 is blocked from the vent hole 12. When the oil drain connector 13 is in the oil drain position, the oil passage gap 14 is connected to the vent hole 12.

[0044] In this embodiment, the control problem of switching between sealing and draining functions is solved by establishing a direct correspondence between mechanical position and oil circuit state. When the connector is in the sealing position, the conical surface mating generates a large contact pressure, ensuring complete blockage of the oil circuit; when switching to the draining position, the formed annular oil passage gap 14 controls the oil flow rate within a reasonable range of 0.2-0.5 m / s. Compared with the existing technology that separately controls sealing and draining, this embodiment integrates the two functions into the displacement change of a single component, reducing the operation steps by more than 50% and avoiding the risk of seal failure caused by multi-component coordination. The axial displacement control method reduces the operating torque to below 0.5 N·m, significantly improving maintenance convenience.

[0045] For example, in this embodiment, the sealing position achieves physical sealing through axial contact, wherein the contact surface can adopt a tapered fit structure with a cone angle ranging from 30° to 60°; the drain position forms a separation gap of 0.5-2mm through axial displacement, and this gap size must ensure oil flow and prevent excessive leakage. As a preferred embodiment, the sealing position can be automatically reset by an elastic element, such as a compression spring providing an axial preload of 3-5N; the drain position can be locked in position by a threaded adjustment mechanism. Furthermore, the position switching can be equipped with a mechanical limiting structure, including but not limited to a slot, a retaining ring, or a limiting screw, to ensure that the working position accuracy is within ±0.1mm and to prevent hydraulic oil leakage caused by excessive unscrewing of the drain connector 13.

[0046] For example, the end of the exhaust port 12 away from the left piston groove 5 is a first tapered opening with an inwardly narrowed diameter. The mating part 1302 is provided with a second tapered opening that mates with the first tapered opening. The taper of the first tapered opening is greater than that of the second tapered opening, so a portion of the second tapered opening can enter the interior of the exhaust port 12. The sidewall of the second tapered opening abuts against the first tapered opening to achieve a seal of the exhaust port 12. In a specific embodiment, the first tapered opening is formed into an inwardly converging conical surface structure by machining or casting, and its taper range is preferably 15°-30°; the second tapered opening is made of elastically deformable metal or composite material, and its taper range is preferably 5°-10°.

[0047] It is worth noting that in this embodiment, the second conical opening can be configured as a continuous conical surface or a segmented conical surface, and its inner wall can be provided with an annular sealing groove to accommodate the sealing ring. In a specific embodiment, the taper difference between the first and second conical openings is controlled within the range of 5°-15° to ensure the formation of effective radial sealing pressure.

[0048] It should also be noted that, in this embodiment, due to the multiple venting slots and the oil drain connector 13, when the motorcycle needs to drain or change oil, the two oil drain connectors 13 can be opened to allow the hydraulic oil inside the caliper to be discharged from the two venting holes 12, thereby improving the oil draining efficiency.

[0049] In an exemplary embodiment, the oil drain channel includes a first oil hole 1303 arranged radially along the oil drain connector 13 and a second oil hole 1304 arranged axially along the oil drain connector 13, wherein the first oil hole 1303 and the second oil hole 1304 are in communication.

[0050] In this embodiment, a three-dimensional intersecting oil passage is formed by providing a radially connected first oil hole 1303 and an axially connected second oil hole 1304. The radially arranged first oil hole 1303 can quickly connect with the vent hole 12, while the axially arranged second oil hole 1304 provides a smooth oil flow path. The interconnected design of the two oil holes effectively expands the oil discharge cross-sectional area and reduces oil flow resistance. Specifically, when the oil discharge connector 13 is in the oil discharge position, hydraulic oil can enter the first oil hole 1303 through the vent hole 12 via the oil passage gap 14, and then smoothly discharge through the second oil hole 1304.

[0051] For example, the first oil hole 1303 is arranged radially along the oil drain connector 13, and its axis is perpendicular to the axis of the oil drain connector 13. The second oil hole 1304 is arranged axially along the oil drain connector 13, and its axis coincides with the axis of the oil drain connector 13. The two oil holes intersect and communicate inside the oil drain connector 13, forming a three-dimensional intersecting oil passage. As a preferred embodiment, the first oil hole 1303 can be located at the bottom of the oil drain connector 13, and mate with the oil passage gap 14. The second oil hole 1304 can penetrate the entire axial length of the oil drain connector 13, forming a smooth oil flow path. In a specific embodiment, the diameters of the first oil hole 1303 and the second oil hole 1304 can be adjusted according to actual oil draining requirements to optimize oil draining efficiency.

[0052] For example, in this embodiment, the number of first oil holes 1303 can be multiple, so as to improve the efficiency of hydraulic oil entering the second oil hole 1304.

[0053] It is worth noting that the left caliper body 1 is provided with an oil inlet hole 2, and a right piston groove 9 communicating with the oil inlet hole 2 is also provided on the left caliper body 1. Simultaneously, the right caliper body 8 is provided with a first oil passage communicating with the left piston groove 5, and a second oil passage is provided on the left caliper body 1, one end of which communicates with the right piston groove 9, and the other end of which communicates with the first oil passage. Through the oil inlet hole 2, the first oil passage, and the second oil passage, hydraulic oil can enter the left piston groove 5 and the right piston groove 9 to drive the first piston 6 and the second piston 10 closer to the brake disc, thereby driving the first brake pad 7 and the second brake pad 11 closer together and into contact with the brake disc, thus achieving braking.

[0054] In an exemplary embodiment, a first piston 6 is provided in the left piston groove 5, and a first brake pad 7 is provided at the end of the left piston groove 5. A second piston 10 is provided in the right piston groove 9, and a second brake pad 11 is provided at the end of the right piston groove 9. The connecting assembly includes a connecting rod 3 and a positioning rod 4 disposed on the left caliper 1. The connecting rod 3 passes through the left caliper 1 and is threadedly connected to the right caliper 8. The positioning rod 4 passes through the first brake pad 7 and the second brake pad 11 and is connected to the right caliper 8.

[0055] In this embodiment, the positioning rod 4 ensures a stable positioning relationship between the left caliper body 1, the right caliper body 8, the first brake pad 7, and the second brake pad 11. The left caliper body 1 and the right caliper body 8 are then connected via the connecting rod 3. The threaded connection of the connecting rod 3 enables quick assembly and disassembly of the caliper bodies. The positioning rod 4 passes through both brake pads and connects to the right caliper body 8, effectively limiting the axial displacement of the brake pads. The addition of the retaining spring 15 further enhances the connection reliability and prevents loosening during use. Compared with existing technologies, this design simplifies the installation process and ensures the working stability of the brake pads through multiple positioning mechanisms.

[0056] For example, the motorcycle caliper also includes a retaining spring 15. One end of the retaining spring 15 is engaged with the outer wall of the left caliper body 1 and the right caliper body 8, and the other end of the retaining spring 15 passes around the positioning rod 4 and is located between the left caliper body 1 and the right caliper body 8. In this embodiment, the retaining spring 15, the left and right calipers, and the positioning rod 4 form a firm positioning relationship. The retaining spring 15 has an arc-shaped portion that cooperates with the positioning rod 4. When installing the retaining spring 15, it is only necessary to engage one end of the retaining spring 15 with the side wall of the left and right calipers, and let the other end pass around the positioning rod 4. The other end is in contact with the first brake pad 7 and the second brake pad 11, thereby realizing the function of the retaining spring 15.

[0057] It is worth noting that the retaining ring 15 can be made of spring steel or stainless steel, and its cross-sectional shape includes, but is not limited to, circular, rectangular, or irregular shapes. The retaining ring 15 can engage with the outer wall of the clamp body using a hook-shaped end, a U-shaped groove, or an elastic clamping structure. The positioning rod 4 and the retaining ring 15 can be coupled in the following ways: the retaining ring 15 forms a ring-shaped clamping structure in the middle, a spiral winding structure, or a segmented elastic clamping structure. The retaining ring 15 can be installed on the side wall of the clamp body near the connecting rod 3, or symmetrically distributed in the area of ​​concentrated force on the clamp body.

[0058] This utility model also proposes a motorcycle that includes the aforementioned easy-to-install motorcycle caliper.

[0059] In summary, this utility model solves the problem of limited installation space and difficult maintenance of traditional calipers due to exhaust components by providing multiple exhaust holes 12 on the mounting part 801 of the right caliper body 8, so as to facilitate connection with the motorcycle's wiring from multiple angles.

[0060] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
