Description

Technical Field

[0001] This utility model relates to the field of transportation technology, and more specifically, to the front wheel brake assembly of an electric tricycle. Background Technology

[0002] Electric tricycles, commonly known as "three-wheeled vehicles," are three-wheeled transportation tools powered by batteries and driven by electric motors for hauling goods or carrying passengers. Electric tricycles have advantages such as strong applicability, maneuverability, simple maintenance, convenient repair, and low price. They can flexibly navigate narrow roads and are widely used in short-distance transportation fields such as households, urban and rural areas, individual rentals, factories, mines, sanitation, and community cleaning.

[0003] In the braking system of electric tricycles, the front wheel brake assembly is a crucial component for ensuring driving safety. Traditional electric tricycle front wheel brake assemblies typically use a single-piece brake disc design, a structure with significant drawbacks over long-term use. When localized wear occurs on the brake disc, users are forced to replace the entire disc because the worn area cannot be replaced individually, resulting in resource waste and significantly increased operating costs. Furthermore, the disassembly and assembly of a single-piece brake disc is cumbersome, requiring specialized tools and a high level of technical skill from repair personnel, greatly reducing the convenience and efficiency of maintenance. Therefore, improvements are necessary. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a front wheel brake assembly for electric tricycles, which has the advantages of modular brake discs that can be independently replaced and convenient and efficient disassembly and assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a front wheel brake assembly for an electric tricycle, comprising:

[0006] A fixing ring, wherein a disc is attached to the inner surface of the outer surface of the fixing ring, and there are four discs, each of which has a groove and a circular slot on its outer surface.

[0007] A disassembly / assembly mechanism is disposed on the outer surface of the disc.

[0008] The disassembly and assembly mechanism includes an arc-shaped block, which is fixedly connected to the outer surface of the disc. The outer surface of the arc-shaped block fits against the inner surface of the outer surface of the fixing ring. Two clamps abut against the outer surface of the arc-shaped block. A fixing shaft is movably sleeved inside one end of each clamp. An arc-shaped strip is fixedly installed at the end of each clamp away from the fixing shaft. A screw is movably sleeved inside the arc-shaped strip. A nut is threaded onto the outer surface of the screw. The outer surface of the nut abuts against the outer surface of the arc-shaped strip.

[0009] As a preferred embodiment of this utility model, a braking module is provided around the disc, and a brake pad is provided inside the braking module.

[0010] As a preferred embodiment of this utility model, a connecting block is fixedly installed on one side of each of the four discs, and a short groove is provided on the side of each of the four discs away from the connecting block. The connecting block and the short groove are used in conjunction.

[0011] As a preferred embodiment of this utility model, a flow guide block is fixedly installed inside the disc, and a through hole is provided on the fixing ring.

[0012] As a preferred embodiment of this utility model, a connecting ring is fixedly installed inside the fixing ring, a fixing block is abutted against the outer surface of the connecting ring, and an assembly hole is provided inside the fixing block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This electric tricycle's front wheel brake assembly addresses the limitation of traditional integral brake discs, which cannot be partially replaced. It innovatively adopts a modular design, dividing the brake disc into four equal parts.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] like Figures 1 to 5 As shown, this utility model provides a front wheel brake assembly for an electric tricycle, comprising:

[0024] A fixing ring 1, with a disc 2 attached to the inner surface of the outer surface of the fixing ring 1, and four discs 2 in total. The outer surfaces of the four discs 2 are all provided with grooves 13 and circular grooves 14.

[0025] The disassembly and assembly mechanism is located on the outer surface of the disc 2;

[0026] The disassembly and assembly mechanism includes an arc-shaped block 5, which is fixedly connected to the outer surface of the disc 2. The outer surface of the arc-shaped block 5 fits against the inner surface of the outer surface of the fixing ring 1. The outer surface of the arc-shaped block 5 abuts against a clamp 6. There are two clamps 6. A fixing shaft 7 is movably sleeved inside one end of each clamp 6. An arc-shaped strip 8 is fixedly installed at the end of each clamp 6 away from the fixing shaft 7. A screw 9 is movably sleeved inside the arc-shaped strip 8. A nut 10 is threaded onto the outer surface of the screw 9. The outer surface of the nut 10 abuts against the outer surface of the arc-shaped strip 8.

[0027] The retaining ring 1 serves as the basic load-bearing component of the brake assembly, forming the installation space for the disc 2 and providing a stable installation reference for the entire braking system. The disc 2 adopts a modular design, with each disc being one-quarter of a complete brake disc. The grooves 13 and circular slots 14 on the outer surface increase the roughness of the friction contact surface to improve the braking effect. In the disassembly and assembly mechanism, the arc-shaped block 5 is fixed to the outer surface of the disc 2 and fits against the retaining ring 1 to form an initial positioning structure. The clamp 6 is hinged to the fixed shaft 7 and can rotate around the fixed shaft to clamp or loosen the arc-shaped block 5. The threaded connection of the screw 9 and the nut 10 enables quick locking and disassembly of the disc 2. The replacement of a single disc can be completed without tools, significantly reducing maintenance costs.

[0028] The disc 2 is surrounded by a braking module 11, and the braking module 11 contains a brake pad 12.

[0029] The brake module 11 contains brake fluid, transmits braking pressure through the hydraulic system, and pushes the brake pads 12 to move in opposite directions to fit against the outer surface of the disc 2. It is the core component for power transmission to realize the braking function. The brake pads 12, as direct friction braking elements, contact the outer surface of the disc 2 under the hydraulic drive of the brake module 11, and decelerate the vehicle through frictional resistance.

[0030] Among them, a connecting block 3 is fixedly installed on one side of each of the four discs 2, and a short groove 4 is opened on the side of each of the four discs 2 away from the connecting block 3. The connecting block 3 and the short groove 4 are used together.

[0031] Each disc 2 has a connecting block 3 on one side and a short groove 4 on the other side. During assembly, the connecting block 3 of adjacent discs is embedded in the short groove 4 to form a mortise and tenon joint structure. This design enhances the circumferential and radial stability between modules through mechanical interlocking when the discs 2 are assembled into a complete brake disc, avoids the risk of brake failure due to module loosening during high-speed rotation, and ensures the uniform transmission of force during braking.

[0032] The disc 2 has a flow guide block 15 fixedly installed inside, and the fixing ring 1 has a through hole 16.

[0033] The guide block 15 is fixed inside the disc 2 and its shape is designed as an air guide channel. When the vehicle is moving, it guides the external air into the disc 2 along a preset path. The through hole 16 is opened on the fixing ring 1 and communicates with the guide channel inside the disc 2, so that the air carries away the heat generated by friction of the disc 2 during the flow process, avoids the disc 2 from overheating and causing brake fade, and improves the continuous working reliability of the braking system.

[0034] The connecting ring 17 is fixedly installed inside the fixing ring 1, and the outer surface of the connecting ring 17 abuts against the fixing block 18. The fixing block 18 has an assembly hole 19 inside.

[0035] The connecting ring 17 is fixed inside the fixing ring 1 and serves as a connection medium between the brake assembly and the front wheel hub. Since the fixing block 18 has an assembly hole 19 inside, the assembly hole 19 is directly used to connect with the front wheel hub and is the key interface for fixing the brake assembly, ensuring the coaxiality and load-bearing strength of the brake system and the wheel hub.

[0036] The connecting ring 17 has a bolt 20 movably sleeved inside, the outer surface of the bolt 20 movably sleeved inside the fixing block 18, and a nut 21 threadedly sleeved at the bottom end of the bolt 20, with the top end of the nut 21 abutting against the outer surface of the connecting ring 17.

[0037] Bolt 20 passes through the inside of connecting ring 17 and is movably sleeved with fixing block 18. Its bottom end is threaded and engages with nut 21. When nut 21 is tightened, fixing block 18 can be tightly pressed against the outer surface of connecting ring 17 to form a rigid connection, preventing fixing block 18 from shifting or loosening during braking.

[0038] Working principle and usage process of this utility model:

[0039] When the operator needs to brake the electric tricycle, the hydraulic pressure inside the brake module 11 increases with the braking operation. Driven by the hydraulic pressure, the two brake pads 12 move in opposite directions until they come into close contact with the outer surface of the disc 2. Because the outer surface of the disc 2 is designed with grooves 13 and circular slots 14, these structures effectively increase the friction between the disc 2 and the brake pads 12, thereby enhancing the friction during braking. This allows the brake pads 12 to decelerate the vehicle until it comes to a complete stop by the resistance generated by rubbing against the disc 2. Simultaneously, the guide block 15 fixed inside the disc 2 guides the airflow during vehicle movement. Outside air enters the disc 2 under the guidance of the guide block and forms air convection inside the disc 2 through the through-holes 16 on the fixing ring 1. This dissipates the heat generated by friction during braking, preventing the disc 2 from overheating and reducing braking performance, thus ensuring the continuous and stable operation of the braking system.

[0040] During the maintenance and replacement of disc 2, given that the brake disc adopts a modular design, consisting of four independent discs 2 spliced ​​together to form a complete braking surface, the actual wear degree of each disc 2 may vary due to uneven force. Operators do not need to replace the entire brake disc; they only need to replace the severely worn individual disc 2. The specific disassembly steps are as follows: First, the operator unscrews nut 10. Since nut 10 and screw 9 are threaded, as nut 10 rotates along the outer surface of screw 9 and moves away from the arc-shaped strip 8, it eventually disengages from the outer surface of screw 9. After removing nut 10, screw 9 can be pulled out from inside the two arc-shaped strips 8. At this point, the two clamps 6, no longer restrained by screw 9, can rotate in the opposite direction around the fixed shaft 7. When the clamps 6 rotate outward until they no longer abut against the arc-shaped block 5, the locking state of disc 2 is released, and the operator can directly remove disc 2 from inside the fixing ring 1, completing the disassembly of the old disc 2.

[0041] When installing the new disc 2, first align the new disc 2 with the installation position on the outer surface of the fixing ring 1, so that the arc-shaped block 5 on the edge of the disc 2 fits against the inner wall of the fixing ring 1, ensuring the initial positioning of the disc 2; then rotate the two clamps 6 inward around the fixing shaft 7, so that the inner wall of the clamp 6 tightly abuts against the outer surface of the arc-shaped block 5, forming an initial clamping of the disc 2; next, pass the screw 9 through the reserved holes of the two arc-shaped strips 8, and then screw the nut 10 onto the outer surface of the screw 9. When the outer surface of the nut 10 contacts the arc-shaped strip 8, the screw 9 will cooperate with the nut 10 to lock the movement of the arc-shaped strip 8 and the clamp 6 as a whole, thus completing the fixing and locking of the disc 2; after all four discs 2 are installed in place, the connecting block 3 on one side of each disc 2 will be precisely embedded into the short groove 4 of the adjacent disc. Through the tenon and mortise cooperation between the connecting block 3 and the short groove 4, the overall structural integrity of the four discs 2 after splicing is effectively enhanced, ensuring that the brake disc remains stable when rotating at high speed and avoiding the impact of local loosening on the braking effect. The entire process achieves independent assembly and disassembly of a single disc 2 through modular design, which greatly reduces maintenance costs and operational difficulty. At the same time, the synergistic effect of heat dissipation and friction enhancement structure balances braking performance and service life.
