Description

Technical Field

[0001] The utility model relates to the technical field of suspension spring steel wires, in particular to an automobile suspension spring steel wire with convenient installation. Background Technique

[0002] Automobile suspension springs are usually made of high-strength steel wires. Carbon steel spring wires are the most commonly used wire materials. They are specially treated and heat-treated to ensure that they can withstand repeated loads and impacts during vehicle operation and are suitable for general suspension systems.

[0003] After retrieval, an automobile suspension spring steel wire with convenient disassembly and assembly, with the publication number CN219692123U, includes a barrel sleeve. A fixed barrel is fixedly connected to the top of the barrel sleeve. A chute is arranged at the top of the fixed barrel. Vertical grooves are arranged on both the left and right sides of the inner wall of the chute. Fixed rods are arranged on the inner walls of the vertical grooves. In the utility model, through the fixed rods, grooves and vertical grooves, the trouble of workers during installation or disassembly is solved. The sound insulation cover outside the fixed barrel can not only reduce the sound of the buffer of the spring steel wire body, but also prevent dust and gravel from entering the device, improving the driving experience and the service life of the device. When the spring steel wire body is deformed or broken after being used for too long, the fixed bottom plate will move downward and contact the pressure plate, and then the device is supported by the buffer spring and the air spring, avoiding the device being too low, which may cause the vehicle chassis to rub against the ground and lead to vehicle rollover.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figures 1-3, An embodiment provided by the present utility model: An automobile suspension spring wire with convenient installation, including a barrel sleeve 1. In the middle of the top end of the barrel sleeve 1, a fixed barrel 2 is fixedly connected. At the left and right ends of the fixed barrel 2, clamping grooves 16 are opened. On the upper parts of the front and rear sides of the inner wall of the fixed barrel 2, arc-shaped rings 8 are fixedly connected. An acoustic insulation barrel 4 is sleeved on the outer wall of the fixed barrel 2. At the top end of the acoustic insulation barrel 4, a top plate 5 is fixedly connected, which is a component for bearing external forces. On the lower sides of the left and right ends of the inner wall of the acoustic insulation barrel 4, sliding rods 10 are slidably connected. At the outer ends of the sliding rods 10, pressing plates 13 are fixedly connected. At the inner ends of the sliding rods 10, they are respectively fixedly connected to the upper sides of the opposite ends of a connecting plate 11. At the lower sides of the opposite ends of the connecting plate 11, blocking blocks 12 are fixedly connected. Refer to Figure 4 , The distance between the front and rear ends of the blocking block 12 is greater than the distance between the opposite ends of the two arc-shaped rings 8. On the lower sides of the left and right ends of the inner wall of the acoustic insulation barrel 4 and below the connecting plate 11, limiting blocks 15 are fixedly connected. The distance between the front and rear ends of the limiting blocks 15 is the same as the distance between the front and rear ends of the inner wall of the clamping groove 16. On the outer sides of the opposite ends of the pressing plates 13 and located outside the sliding rods 10, tension springs 14 are fixedly connected. The other ends of the tension springs 14 are respectively fixedly connected to the left and right ends of the acoustic insulation barrel 4. At the bottom end of the top plate 5 and inside the inner wall of the acoustic insulation barrel 4, a spring wire body 9 is fixedly connected. On the left and right sides of the top end of the barrel sleeve 1, cavity barrels 3 are fixedly connected.

[0026] Specifically, install the two sides of the barrel sleeve 1 in the vehicle by welding. Then, align the acoustic insulation barrel 4 with the outside of the fixed barrel 2. After aligning the limiting blocks 15 with the clamping grooves 16, slip them on. At the same time, press the two pressing plates 13 on both sides, so that the sliding rods 10 push the connecting plate 11 to move towards each other and compress the tension springs 14, thereby making the distance between the opposite ends of the blocking blocks 12 smaller than the inner diameter of the arc-shaped ring 8. Then, after the blocking blocks 12 reach the lower side of the arc-shaped ring 8, release the pressing plates 13, and drive the pressing plates 13 to reset under the elastic force of the tension springs 14, causing the opposite ends of the blocking blocks 12 to fit against the inner wall of the fixed barrel 2, and its top is also restricted below the arc-shaped ring 8, preventing the acoustic insulation barrel 4 from falling off the outside of the fixed barrel 2 due to the elastic force of the spring wire body 9 during use. After installation, the bottom of the spring wire body 9 will contact the inner wall of the fixed barrel 2, thereby realizing the installation of the spring wire body 9.

[0027] Refer to Figure 5 , A sliding disk 17 is slidably connected to the inner wall of the cavity barrel 3. At the top end of the sliding disk 17, an extension rod 6 is fixedly connected. At the bottom end of the sliding disk 17, a buffer spring 18 is fixedly connected. The other end of the buffer spring 18 is fixedly connected to the inner wall of the cavity barrel 3. At the top end of the extension rod 6, a pressing plate 7 is fixedly connected. The distance between the opposite ends of the pressing plate 7 is smaller than the diameter of the outer wall of the top plate 5. The distance between the front and rear ends of the inner wall of the clamping groove 16 is greater than the diameter of the outer wall of the sliding rod 10. The front and rear ends of the inner wall of the clamping groove 16 and the opposite ends of the arc-shaped ring 8 are located on the same horizontal plane.

[0028] Specifically, when the spring wire body 9 is in use, it will be squeezed by force. At the same time, the top plate 5 at the top will press down the two side pressing plates 7, causing the extension rod 6 to move downward and push the sliding plate 17 to press down the buffer spring 18, so as to produce a buffering effect on both sides of the bottom of the top plate 5, and then buffer the external force received by the spring wire body 9, avoiding excessive force on the spring wire body 9 and causing damage or fracture, thereby improving its service life. Compared with the comparative patent, in this utility model, the buffer spring 18 is placed inside the cavity cylinder 3, which can improve the protection of the buffer spring 18, reduce the contact between the buffer spring 18 and external air moisture, reduce the corrosion effect on its surface, and improve its service life.

[0029] Working principle: First, install the two sides of the sleeve 1 in the car by welding, then align the sound insulation cylinder 4 with the outside of the fixed cylinder 2, and insert the limit block 15 into the card slot 16. At the same time, press the two side pressing plates 13, so that the sliding rod 10 pushes the connecting plate 11 to move towards each other and squeeze the tension spring 14, so that the distance between the opposite ends of the blocking block 12 is less than the inner wall diameter of the arc ring 8. Then, after the blocking block 12 reaches the lower side of the arc ring 8, release the pressing plate 13, and drive the pressing plate 13 to reset under the elastic force of the tension spring 14, causing the opposite ends of the blocking block 12 to fit with the inner wall of the fixed cylinder 2, and its top is also restricted under the arc ring 8, to prevent the sound insulation cylinder 4 from falling off the outside of the fixed cylinder 2 due to the elastic force of the spring wire body 9 during use. When the spring wire body 9 is in use, it will be squeezed by force. At the same time, the top plate 5 at the top will press down the two side pressing plates 7, causing the extension rod 6 to move downward and push the sliding plate 17 to press down the buffer spring 18, so as to produce a buffering effect on both sides of the bottom of the top plate 5, and then buffer the external force received by the spring wire body 9, avoiding excessive force on the spring wire body 9 and causing damage or fracture, thereby improving its service life.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
