Technical Field

[0001] This utility model belongs to the field of disc brake assembly technology and relates to a disc brake assembly for electric motorcycles. Background Technology

[0002] Electric motorcycles, as an environmentally friendly and convenient means of transportation, have been widely used in modern society. The disc brake assembly is a crucial braking component of electric motorcycles, and its braking performance directly affects riding safety. However, existing electric motorcycle disc brake assemblies have some problems during use, resulting in less than ideal braking performance.

[0003] Existing disc brake assemblies for electric motorcycles generate significant heat between the brake disc and brake pads during braking. Due to poor heat dissipation, this can easily lead to overheating of the brake disc and pads, resulting in decreased braking performance, heat fade, and compromised braking effectiveness and riding safety. Furthermore, the uneven distribution of braking force and suboptimal structural design in existing disc brake assemblies also negatively impact braking performance. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned problems by providing an electric motorcycle disc brake assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electric motorcycle disc brake assembly includes a left upper pump assembly and a right upper pump assembly. One side of each assembly is connected to an oil pipe assembly, and the other end of the oil pipe assembly is connected to a lower pump assembly and a three-cylinder opposed cylinder assembly. The oil pipe assembly includes a first oil pipe and a second oil pipe. One end of the first oil pipe is connected to the right upper pump assembly, and the other end is connected to the three-cylinder opposed cylinder assembly. One end of the second oil pipe is connected to the left upper pump assembly, and the other end is connected to the lower pump assembly and the three-cylinder opposed cylinder assembly respectively via an oil circuit control assembly.

[0007] In the aforementioned disc brake assembly for electric motorcycles, both the left upper pump assembly and the right upper pump assembly include a mounting bracket, a brake lever, and a reservoir. The mounting bracket is fixedly mounted on the steering handle of the electric motorcycle. One side of the brake lever is movably hinged to the mounting bracket, and a pressure rod is fixedly provided on the other side of the brake lever. The reservoir is fixedly mounted above the mounting bracket.

[0008] In the aforementioned electric motorcycle disc brake assembly, an upper pump piston is installed inside the oil reservoir. The upper pump piston is sealed to the oil reservoir.

One side of the upper pump piston is in contact with the pressure rod, and a spring is provided on the other side of the upper pump piston. The spring is located inside the oil reservoir.

[0009] In the aforementioned electric motorcycle disc brake assembly, the oil reservoir has an internal cavity, and a sealing cap is fixed to the top of the oil reservoir by bolts. Switch wires are connected to the left upper pump assembly and the right upper pump assembly.

[0010] In the aforementioned electric motorcycle disc brake assembly, the hydraulic control component includes a transfer pipe, a third hydraulic pipe, and a fourth hydraulic pipe. One end of the third and fourth hydraulic pipes is connected to the transfer pipe, the other end of the third hydraulic pipe is connected to the lower pump assembly, and the other end of the fourth hydraulic pipe is connected to the three-cylinder opposed cylinder assembly.

[0011] In the aforementioned electric motorcycle disc brake assembly, the adapter pipe is provided with a first connection port, a second connection port, and a third connection port. The first connection port is connected to a second oil pipe, the second connection port is connected to a third oil pipe, and the third connection port is connected to a fourth oil pipe.

[0012] In the aforementioned electric motorcycle disc brake assembly, the three-cylinder opposed cylinder assembly is provided with a first connecting pipe and a second connecting pipe.

The surface of the brake disc has multiple evenly distributed heat dissipation holes that extend from the center of the brake disc to the edge.

[0014] In the aforementioned disc brake assembly for electric motorcycles, the brake pads are housed within the brake caliper body and symmetrically distributed on both sides of the brake disc.

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] like Figure 1-8 As shown, an electric motorcycle disc brake assembly includes a left upper pump assembly 1 and a right upper pump assembly 2. One side of each assembly is connected to an oil pipe assembly, and the other end of the oil pipe assembly is connected to a lower pump assembly 3 and a three-cylinder opposed cylinder assembly 4. The oil pipe assembly includes a first oil pipe 5 and a second oil pipe 6. One end of the first oil pipe 5 is connected to the right upper pump assembly 2, and the other end is connected to the three-cylinder opposed cylinder assembly 4. One end of the second oil pipe 6 is connected to the left upper pump assembly 1, and the other end is connected to the lower pump assembly 3 and the three-cylinder opposed cylinder assembly 4 respectively via an oil circuit control assembly 7.

[0031] Furthermore, both the left upper pump assembly 1 and the right upper pump assembly 2 include a mounting bracket 8, a brake handle 9, and an oil reservoir 10. The mounting bracket 8 is fixedly mounted on the steering handle of the electric motorcycle. One side of the brake handle 9 is movably hinged to the mounting bracket 8, and a pressure rod 11 is fixedly provided on the other side of the brake handle 9. The oil reservoir 10 is fixedly mounted above the mounting bracket 8.

[0032] In this embodiment, when the operator grips the brake handle 9, the pressure rod 11 pushes the piston 30 to move within the hydraulic cylinder 27, thereby pressing the hydraulic oil out of the reservoir 10 and delivering it through the oil pipe assembly to the lower pump assembly 3 and the three-cylinder opposed cylinder assembly 4, pushing the brake pads 25 to press against the brake disc 24, thus achieving the braking effect.

[0033] Furthermore, an upper pump piston 12 is installed inside the oil reservoir 10. The upper pump piston 12 is sealed to the oil reservoir 10. One end of the upper pump piston 12 is located inside the oil reservoir 10, and the other end is located outside the oil reservoir 10. One side of the upper pump piston 12 is in contact with the pressure rod 11. A spring 13 is provided on the other side of the upper pump piston 12. The spring 13 is located inside the oil reservoir 10.

[0034] In this embodiment, when the operator releases the brake handle 9, the spring force of the spring 13 pushes the upper pump piston 12 to reset, thereby drawing back some of the hydraulic oil in the reservoir 10, reducing the pressure inside the reservoir 10, and decreasing the friction between the brake pads 25 and the brake disc 24, thus releasing the brakes. Simultaneously, the sealed connection between the upper pump piston 12 and the reservoir 10 ensures the hydraulic oil's tightness, preventing leakage and extending the service life of the braking system.

[0035] Furthermore, the oil reservoir 10 has an internal cavity, and a sealing cap 14 is fixedly installed on the top of the oil reservoir 10 by bolts. Switch wires 15 are connected to the left upper pump assembly 1 and the right upper pump assembly 2.

[0036] In this embodiment, the sealing cap 14 is fixedly installed on the top of the oil reservoir 10 by bolts, ensuring the airtightness of the inside of the oil reservoir 10, effectively preventing dust, moisture and other impurities from entering, and ensuring the cleanliness of the hydraulic oil and the stability of the system. The switch wires 15 connected to the left upper pump assembly 1 and the right upper pump assembly 2 provide convenience for the electrical control of the braking system.

[0037] Furthermore, the oil circuit control component 7 includes a transfer pipe 16, a third oil pipe 17, and a fourth oil pipe 18. One end of the third oil pipe 17 and the fourth oil pipe 18 are both connected to the transfer pipe 16. The other end of the third oil pipe 17 is connected to the lower pump assembly 3, and the other end of the fourth oil pipe 18 is connected to the three-cylinder opposed cylinder assembly 4.

[0038] In this embodiment, during braking, hydraulic oil can be quickly transmitted to the corresponding lower pump assembly and opposed cylinder assembly through the third oil pipe 17 and the fourth oil pipe 18, thereby achieving a fast and stable braking effect.

[0039] Furthermore, the adapter pipe 16 is provided with a first connection port 19, a second connection port 20 and a third connection port 21. The first connection port 19 is connected to the second oil pipe 6, the second connection port 20 is connected to the third oil pipe 17, and the third connection port 21 is connected to the fourth oil pipe 18.

[0040] In this embodiment, by providing the first connection port 19, the second connection port 20, and the third connection port 21, the adapter pipe 16 can efficiently distribute hydraulic oil from the oil reservoir 10 to the various required components. This improves the transmission efficiency of the hydraulic oil and ensures the response speed and stability of the braking system.

[0041] Furthermore, the three-cylinder opposed cylinder assembly 4 is provided with a first connecting pipe 22 and a second connecting pipe 23. The first connecting pipe 22 is connected to the first oil pipe 5, and the second connecting pipe 23 is connected to the fourth oil pipe 18.

[0042] In this embodiment, the arrangement of the first connecting pipe 22 and the second connecting pipe 23 allows the three-cylinder opposed cylinder assembly 4 to simultaneously receive hydraulic oil from different oil circuits. Specifically, the first oil pipe 5 connected to the first connecting pipe 22 provides hydraulic oil to drive the main braking function of the three-cylinder opposed cylinder assembly 4. The fourth oil pipe 18 connected to the second connecting pipe 23 provides additional hydraulic oil during braking to enhance braking performance or serves as a backup oil circuit to ensure braking reliability.

[0043] Furthermore, both the lower pump assembly 3 and the three-cylinder opposed cylinder assembly 4 include a brake disc 24, a brake pad 25, a brake caliper 26, and a hydraulic cylinder 27. The brake disc 24 is circular and is mounted on the wheel hub of the electric motorcycle. The surface of the brake disc 24 is provided with a plurality of evenly distributed heat dissipation holes 28, which extend from the center of the brake disc 24 to the edge.

[0044] In this embodiment, the heat dissipation holes 28 significantly improve the heat dissipation efficiency of the brake disc 24, effectively preventing the brake disc from overheating and affecting braking performance due to prolonged braking. The brake pads 25 are tightly attached to one side of the brake disc 24. When the hydraulic cylinder 27 pushes the brake caliper 26, the brake pads 25 and brake disc 24 come into close contact, generating friction and achieving the braking function. The brake caliper 26 not only fixes the brake pads but also ensures uniform distribution of braking force through its internal structural design, improving braking stability and comfort. The hydraulic cylinder 27, as the power source of the braking system, provides powerful power support to the braking system through its precise oil pressure control and rapid response speed.

[0045] Furthermore, the brake pads 25 are disposed inside the brake caliper body 26 and symmetrically distributed on both sides of the brake disc 24. The brake caliper body 26 is fixedly installed on the frame of the electric motorcycle and has a hydraulic cylinder 27 inside.

[0046] In this embodiment, the symmetrical distribution design of the brake pads 25 ensures that the force is evenly distributed on both sides during braking, thereby enhancing the stability and balance of braking.

[0047] Furthermore, the hydraulic cylinder 27 includes a cylinder body 29 and a piston 30. The cylinder body 29 is fixed inside the brake caliper body 26, and the piston 30 is connected to the brake pad 25. The hydraulic cylinder 27 is connected to the left upper pump assembly 1 and the right upper pump assembly 2 through oil pipes.

[0048] In this embodiment, when the hydraulic cylinder receives the oil pressure signal from the upper pump assembly, the piston 30 will move quickly, pushing the brake pad 25 to press against the brake disc, thereby quickly realizing the braking action.

[0049] The working principle of this utility model is as follows:

[0050] This invention achieves precise distribution and control of hydraulic oil by incorporating an oil circuit control component 7. During braking, the operator grips the brake lever, causing the pressure rod 11 to push the upper pump piston 12 within the oil reservoir 10, thereby expelling hydraulic oil and delivering it through the oil pipe assembly 7 to the lower pump assembly 3 and the three-cylinder opposed cylinder assembly 4. The adapter pipe 16 in the oil circuit control component 7 efficiently distributes hydraulic oil to the required components through its first connection port 19, second connection port 20, and third connection port 21. This design not only improves the transmission efficiency of hydraulic oil but also ensures the response speed and stability of the braking system.
