Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to a high-strength spring steel wire with a limiting structure. Background Art

[0002] Spring steel wire plays a key role in many application scenarios due to its unique mechanical properties and processing adaptability. For example, automobile suspension springs (coil springs, torsion bar springs, coil springs inside air springs, etc.) are made of spring steel wire to absorb vibrations caused by uneven road surfaces and ensure vehicle driving stability and ride comfort.

[0003] When a spring is subjected to a large impact, an overtravel phenomenon may occur during its reset process, that is, when the spring tries to return to its original position, it briefly passes the initial position and hits the equipment due to excessive energy release or insufficient system damping. This phenomenon may not only cause damage to the spring itself, but also cause impact, wear or damage to related equipment, seriously affecting the service life and normal operation of the equipment. For example, during vehicle driving, the spring, as an important part of the suspension system, bears high-frequency impact caused by uneven road conditions. If the spring design is unreasonable or encounters extreme road conditions, it may cause the spring to overtravel and hit other parts of the suspension system (such as shock absorbers, control arms, etc.). Long-term use will cause premature wear or failure of the suspension components, affecting the driving stability and safety of the vehicle. Therefore, a high-strength spring steel wire with a limiting structure is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] See also Figure 1-Figure 4 , a high-strength spring steel wire with a limiting structure, comprising a spring steel wire body 1, on which a limiting mechanism 2 is arranged;

[0022] The limiting mechanism 2 includes a limiting belt 220 and a connecting ring 210. The connecting ring 210 is sleeved on the spring steel wire body 1 and slidably connected thereto. The limiting belt 220 is detachably mounted on the connecting ring 210. The outer end surface of the spring steel wire body 1 is sprayed with a wear-resistant coating 101. A safety belt 223 is arranged inside the limiting belt 220.

[0023] When assembling the spring steel wire, insert the limiting belt 220 into the expansion joint 211, and install it on the reinforcement ring 222 through the fixing hole 221, ensuring that the fixing hole 221 and the reinforcement ring 222 are tightly matched without looseness, rotate the locking bolt 212 clockwise, pass through the expansion joint 211 and the reinforcement ring 222, and screw into the first screw hole 213, and gradually tighten the locking bolt 212 to make the connecting ring 210 squeeze the expansion joint 211 until the limiting belt 220 is firmly clamped and fixed, and slide the connecting ring 210 to the required limiting position according to actual use requirements. Position, use a wrench or other tool to tighten the fixing bolt 214 to squeeze the spring wire body 1, ensure that the connecting ring 210 is tightly fixed to the spring wire body 1, and prevent the connecting ring 210 from shifting during use. When the spring is in use, when the spring wire body 1 is impacted, it undergoes elastic deformation. When the external force is removed, the spring returns to its original position. When the spring wire body 1 rebounds to the maximum length of the limiting belt 220, the limiting belt 220 limits the rebound of the spring, thereby preventing it from hitting the equipment or causing overtravel damage to the spring.

[0024] Furthermore, an expansion joint 211 is opened on the side of the connecting ring 210, a locking bolt 212 is arranged at the upper end of the expansion joint 211, a first screw hole 213 corresponding to the expansion joint 211 is arranged at the bottom, and a limiting belt 220 is inserted into the expansion joint 211 and slidably connected with the connecting ring 210.

[0025] By tightening the locking bolt 212, the connecting ring 210 squeezes the expansion joint 211, thereby fixing the limiting belt 220. The clamping installation method facilitates the replacement of the limiting belt 220, thereby improving the convenience of spring repair and maintenance.

[0026] Furthermore, a fixing hole 221 is provided on the limiting belt 220 , a reinforcement ring 222 is fixedly installed in the fixing hole 221 , and the locking bolt 212 is inserted into the reinforcement ring 222 and is slidably connected to the limiting belt 220 .

[0027] By opening a fixing hole 221 on the limiting belt 220, the installation stability of the limiting belt 220 is improved to prevent the limiting belt 220 from falling off. By setting a reinforcement ring 222 on the inner end surface of the fixing hole 221, the reinforcement ring 222 can be effectively prevented from being broken.

[0028] Furthermore, the safety belt 223 is made of nylon.

[0029] Nylon has strong resistance to stretching and weathering, and has a long service life, thus reducing the maintenance cycle of the spring.

[0030] Furthermore, a threaded fixing bolt 214 is disposed on the side of the connecting ring 210 .

[0031] The sliding connection structure of the connecting ring 210 facilitates adjustment of the position of the connecting ring 210, thereby adjusting the limit stroke of the spring. The spring steel wire body 1 is squeezed by the fixing bolt 214 to fix the connecting ring 210 and the spring steel wire body 1, thereby preventing the connecting ring 210 from shifting during repeated dragging of the spring steel wire body 1.

[0032] Further, the safety belt 223 is located at the center of the safety belt 223 .

[0033] After aging, the limiting belt 220 is most likely to break in the center when subjected to force. When the limiting belt 220 breaks, the safety belt 223 acts as a safety device to connect the two broken parts, thereby further limiting the reset stroke of the spring and preventing the limiting belt 220 from being entangled on the equipment.

[0034] Furthermore, the wear-resistant coating 101 is made of polytetrafluoroethylene.

[0035] Polytetrafluoroethylene has good wear resistance, which can reduce the wear of the connecting ring 210 on the spring, and has a small friction coefficient, which facilitates the adjustment and installation of the connecting ring 210.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
