Description

Technical Field

[0001] This utility model relates to the field of brake cable technology, and in particular to a brake cable structure with a high safety factor. Background Technology

[0002] Currently, with the development of the automotive industry, vehicle safety performance has received widespread attention. Braking safety is one of the important factors in ensuring driving safety. Traditional brake cables mostly use steel wire ropes as the transmission medium. Although they have high strength and durability, they are prone to corrosion and wear during long-term use, leading to unstable braking force transmission or even failure. In recent years, some new materials and technologies have been introduced into the design of brake cables to improve their reliability and service life.

[0003] A search revealed Chinese Patent Publication No. CN220204349U, which discloses a brake cable belonging to the field of automotive brakes. The cable includes a protective cylinder and a mounting plate. A steel wire rope is slidably mounted inside the protective cylinder, and the steel wire rope passes through the protective cylinder. An oil injection hole is formed on the surface of the steel wire rope, and a sealing bolt is screwed into the inner side of the oil injection hole. Rubber sleeves are symmetrically fitted onto the surface of the protective cylinder, and a fixing sleeve is fitted onto the surface of the rubber sleeve. A notch is formed on the surface of the fixing sleeve, and extension plates are symmetrically arranged on both sides of the notch. Bolts are screwed onto the two extension plates. The extension plate described in section 1 has an installation groove at one end away from the fixed sleeve. One end of the installation plate is placed inside the installation groove. The two ends of one side of the installation plate are symmetrically provided with extension shafts to pass the brake wire rope through the protective cylinder, which facilitates installation and protects the wire rope. Then, a fixed sleeve is fitted on the surface of the protective cylinder. An adjustable mounting plate is provided on the outside of the fixed sleeve to adapt to different mounting surfaces. However, the above structure does not take into account that the brake cable will elongate and loosen to a certain extent after long-term use, which will affect the sensitivity of the brake and pose a great safety hazard. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a brake cable structure with a high safety factor, aiming to improve the problem that in the prior art, brake cables will elongate and loosen to a certain extent after long-term use, which will affect the sensitivity of braking and pose a great safety hazard.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a brake cable structure with a high safety factor, comprising a steel wire rope, a rubber layer slidably connected to the outer wall of the steel wire rope, a braided layer fixedly connected to the outer wall of the rubber layer, a fixing block fixedly connected to both ends of the braided layer, a tension block threadedly connected to the inner wall of the fixing block, a through hole opened in the middle of the tension block, a locking block threadedly connected to the outer wall of the fixing block, a locking surface fixedly connected to the top of the locking block, a fixing joint fixedly connected to the outer wall of the steel wire rope, and a lubrication mechanism provided on the outer wall of the steel wire rope for lubricating the steel wire rope.

[0006] The above technical solution involves: a rubber layer slidably connected to the outer wall of the wire rope, which provides additional protection and absorbs vibration, thereby improving the overall performance of the brake cable; a braided layer fixedly connected to the outer wall of the rubber layer, which further enhances the tensile strength and wear resistance of the brake cable; fixed blocks fixedly connected to both ends of the braided layer; a tension block threadedly connected to the inner wall of the fixed block; a through hole in the middle of the tension block, allowing the wire rope to pass through; a locking block threadedly connected to the outer wall of the fixed block; and a locking surface fixedly connected to the top of the locking block, which effectively locks the tension block and ensures stability; and a fixed joint fixedly connected to the outer wall of the wire rope, which secures the wire rope to the tension block.

[0007] As a further description of the above technical solution:

[0008] The lubrication mechanism includes a lubrication block, the bottom surface of which is rotatably connected to the top surface of the tension block. The lubrication block has an internal cavity, and an oil pipe is connected to the outer wall of the lubrication block. An oil inlet is provided on the inner wall of the oil pipe. A spring seat is fixedly connected to the inner wall of the oil inlet. A second spring is fixedly connected to the outer wall of the spring seat. A piston block is fixedly connected to the other end of the second spring. A pressure rod is fixedly connected to the outer wall of the piston block.

[0009] Through the above technical solution: the bottom surface of the lubricating block and the top surface of the tensioning block are connected by a rotating connection to ensure that the two can rotate flexibly relative to each other. The interior of the lubricating block is carefully designed with a cavity for storing lubricant so that it can effectively lubricate when needed. An oil pipe is connected to the outer wall of the lubricating block. The inner wall of the oil pipe is provided with multiple oil inlets. A spring seat is fixedly connected to the inner wall of the oil pipe. The spring seat keeps the oil inlets unobstructed and is connected to a second spring. The presence of the second spring is to provide a stable thrust during the lubrication process to reset the piston block. The function of the piston block is to push the piston block under the thrust of the pressure rod, so that the lubricating oil can enter the cavity through the oil inlet.

[0010] As a further description of the above technical solution:

[0011] A rotating block is fixedly connected to the outer wall of the tension block, and connecting blocks are fixedly connected to both ends of the wire rope. A connecting hole is opened on the outer wall of the connecting block.

[0012] The above technical solution involves a hexagonal rotating block to facilitate the rotation of the tension block, thereby adjusting the tension of the wire rope. The two ends of the wire rope are fixedly connected to connecting blocks, which can cooperate with other related components to ensure that the braking force transmitted by the wire rope can be accurately applied to the subsequent stages of the entire braking system.

[0013] As a further description of the above technical solution:

[0014] One end of the oil pipe is connected to an oil storage tank, and the inner wall of the oil storage tank is provided with spiral grooves.

[0015] The above technical solution involves connecting one end of the oil pipe to an oil storage tank, which serves as a container for lubricating oil. The inner wall of the oil storage tank has spiral grooves, which provide a way for the installation of other components.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the spiral groove is threaded with a connection port, and a cover is fixedly connected to the top of the connection port.

[0018] Through the above technical solution: the outer wall of the spiral groove is connected to the connection port by threads, and the top of the connection port is fixedly connected to the cover. The cover can prevent dust, impurities and foreign objects from entering the oil tank and affecting the quality of the lubricating oil. It can also ensure that the lubricating oil in the oil tank will not leak due to vibration or other factors during the operation of the braking system, thereby ensuring the stable operation and long service life of the entire braking system.

[0019] As a further description of the above technical solution:

[0020] A spring is fixedly connected to the bottom surface of the connector, and a compression block is fixedly connected to the other end of the spring.

[0021] The above technical solution involves connecting a spring to the bottom of the connector. The spring has a suitable elastic coefficient and can stably extend and retract within a specific pressure range. The other end of the spring is fixedly connected to the extrusion block. The components around the extrusion block cooperate with each other, and their surfaces are smooth to reduce friction.

[0022] As a further description of the above technical solution:

[0023] A handle is fixedly connected to the top surface of the cover, and the outer wall of the extrusion block is slidably connected to the inner wall of the oil storage tank.

[0024] The above technical solution provides that the top surface of the cover is securely connected to the handle, which allows the cover to be easily operated by gripping the handle. The outer wall of the extrusion block is slidably connected to the inner wall of the oil storage tank, ensuring that the extrusion block can move smoothly up and down inside the oil storage tank and allowing for pressure adjustment of the lubricating oil inside the oil storage tank.

[0025] As a further description of the above technical solution:

[0026] One end of the pressure rod is fixedly connected to a contact ball, and multiple brushes are fixedly connected to the inner wall of the lubrication block.

[0027] Through the above technical solution: one end of the pressure rod is fixedly connected to the contact ball. The surface of the contact ball is smooth and round, which can make good contact and interaction with other components. When the contact ball is pushed by an external force, the pressure rod can accurately transmit the force to the corresponding position. The brush can effectively and evenly apply lubricating oil to the surface of the wire rope, thereby reducing friction and improving the performance and service life of the wire rope.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the wire rope is made of multiple strands of wire, which can effectively disperse stress and increase flexibility. The fixed section locks the wire rope, the tension block drives the wire rope to stretch, and the top surface of the locking surface contacts the bottom surface of the rotating block to complete the locking. This realizes the tension adjustment of the wire rope. The brake line will elongate and loosen to a certain extent after long-term use. This can compensate for these changes and ensure the sensitivity of the brake.

[0030] 2. In this utility model, the lubricating oil in the oil storage tank has a certain pressure under the action of the spring. The lubricating oil is blocked by the piston block in the oil pipe. Due to the multi-strand spiral structure of the wire rope, when the wire rope moves, it will continuously push the pressure rod. The pressure rod pushes the piston block, so that the lubricating oil can reach the cavity of the lubrication block from the oil inlet and then be absorbed by the brush. The tail of the brush is in direct contact with the wire rope, thereby lubricating the wire rope, realizing the lubrication of the wire rope, reducing the friction of the wire rope, and thus reducing the wear of the wire rope.

[0042] Specifically, the bottom surface of the lubricating block 201 is connected to the top surface of the tension block 6 by a rotatable connection, ensuring that the two can rotate flexibly relative to each other.

The presence of the second spring 204 is to provide a stable thrust during the lubrication process to reset the piston block 205. The function of the piston block 205 is to push the piston block 205 under the thrust of the pressure rod 207, so that the lubricating oil can enter the cavity 208 from the oil inlets 206.

[0043] Please see the appendix Figure 1 - Appendix Figure 3 A rotating block 10 is fixedly connected to the outer wall of the tension block 6. Both ends of the wire rope 1 are fixedly connected to a connecting block 12. A connecting hole 13 is opened on the outer wall of the connecting block 12. One end of the oil pipe 202 is connected to an oil storage tank 14. A spiral groove 21 is opened on the inner wall of the oil storage tank 14. A connecting port 17 is threaded on the outer wall of the spiral groove 21. A cover 18 is fixedly connected to the top of the connecting port 17.

[0044] Specifically, the rotating block 10 is hexagonal in shape, which facilitates the rotation of the tension block 6, thereby adjusting the tension of the wire rope 1. The two ends of the wire rope 1 are fixedly connected to the connecting block 12. The connecting block 12 can cooperate with other related components to ensure that the braking force transmitted by the wire rope 1 can accurately act on the subsequent links of the entire braking system. One end of the oil pipe 202 is connected to the oil storage tank 14. The oil storage tank 14 serves as a container for lubricating oil. The inner wall of the oil storage tank 14 is provided with a spiral groove 21, which provides a way for the installation of other components. The outer wall of the spiral groove 21 is connected to the connecting port 17 by threads. The top of the connecting port 17 is fixedly connected to the cover 18. The cover 18 can prevent dust, impurities and foreign objects from entering the oil storage tank 14 and affecting the quality of the lubricating oil. It can also ensure that the lubricating oil in the oil storage tank 14 will not leak due to vibration or other factors during the operation of the braking system, thereby ensuring the stable operation and long service life of the entire braking system.

[0045] Please see the appendix Figure 3 - Appendix Figure 5 A spring 16 is fixedly connected to the bottom surface of the connection port 17, and a pressing block 15 is fixedly connected to the other end of the spring 16. A handle 19 is fixedly connected to the top surface of the cover 18. The outer wall of the pressing block 15 is slidably connected to the inner wall of the oil storage tank 14. A contact ball 22 is fixedly connected to one end of the pressure rod 207. Multiple brushes 20 are fixedly connected to the inner wall of the lubrication block 201.

[0046] Specifically, spring 16 is connected to the bottom of connector 17. Spring 16 has a suitable elastic coefficient and can stably expand and contract within a specific pressure range. The other end of spring 16 is fixedly connected to compression block 15. The components around compression block 15 cooperate with each other, and their surfaces are smooth to reduce friction. Handle 19 is firmly connected to the top surface of cover 18. Handle 19 can be easily used to operate cover 18. The outer wall of compression block 15 is slidably connected to the inner wall of oil tank 14, ensuring that compression block 15 can move smoothly up and down in oil tank 14 and can regulate the pressure of lubricating oil in oil tank 14. One end of pressure rod 207 is fixedly connected to contact ball 22. The surface of contact ball 22 is smooth and round, allowing for good contact and interaction with other components. When contact ball 22 is pushed by external force, pressure rod 207 can accurately transmit force to the corresponding position. Brush 20 can effectively and evenly apply lubricating oil to the surface of wire rope 1, thereby reducing friction and improving the performance and service life of wire rope 1.

[0047] Working principle: The wire rope 1 is made of multi-strand steel wires, which can effectively disperse stress and increase flexibility. The rubber layer 3 enables the wire rope 1 to move smoothly. The braided layer 4 can prevent the wire rope 1 from being damaged by external impact. Since the fixed section 9 locks the wire rope 1, when the tension block 6 rotates in the fixed block 5, the fixed section 9 drives the wire rope 1 to stretch. Then, the locking block 7 is rotated so that the top surface of the locking surface 8 contacts the bottom surface of the rotating block 10, thus completing the locking. This prevents the tension block 6 from moving due to vibration during use, thereby changing the tension. The tension of the wire rope 1 can be adjusted. The brake line will elongate and loosen to a certain extent after long-term use. Tension adjustment can compensate for these changes and ensure the sensitivity of the brake.

[0048] The lubricating oil in the oil storage tank 14 has a certain pressure under the action of the spring 16. The lubricating oil is blocked by the piston block 205 in the oil pipe 202. Due to the multi-strand spiral structure of the wire rope 1, when the wire rope 1 moves, it will continuously push the pressure rod 207. The pressure rod 207 pushes the piston block 205, so that the lubricating oil can reach the cavity 208 of the lubrication block 201 from the oil outlet 206, and then be absorbed by the brush 20. The tail of the brush 20 is in direct contact with the wire rope 1, thereby lubricating the wire rope 1, realizing the lubrication of the wire rope 1, reducing the friction of the wire rope 1, and thus reducing the wear of the wire rope 1.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
