Description

Technical Field

[0001] This utility model relates to the technical field of shock absorber accessories, specifically to an aluminum shock absorber ring with an embedded self-lubricating bushing. Background Technology

[0002] As a key connecting component in the vehicle suspension system, the shock absorber eyelet's main function is to connect the shock absorber to the vehicle chassis and to withstand and transmit multi-directional impacts and vibrations during vehicle operation. Traditional eyelet structures often use direct metal connections or are equipped with simple rubber bushings. Direct metal connections can lead to noise and wear problems, while rubber bushings, although they can provide some cushioning, are prone to aging, plastic deformation, or even cracking under long-term high-frequency vibration, complex loads, and harsh environments. This results in increased connection gaps and reduced driving stability and comfort. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a shock absorber aluminum lifting ring with an embedded self-lubricating bushing, which solves the problems of abnormal noise and wear.

[0005] (II) Technical Solution

[0006] To solve the above problems, this utility model achieves the following technical solution: a shock absorber aluminum lifting ring with an embedded self-lubricating bushing, comprising: a lifting ring assembly, wherein a collar is provided inside the lifting ring assembly, a reinforcing rod is fixedly connected to the inner wall of the collar, a locking plate and an arc plate are rotatably connected to the outer wall of the collar via a hinge, an inner liner is slidably connected inside the collar, a fixing groove is formed on the outer wall of the inner liner, an annular groove is formed on the inner wall of the inner liner, a ball is rotatably connected to the inner wall of the groove, a bushing is rotatably connected to the outer wall of the ball, and an oil injection hole is formed on the outer wall of the bushing. The sliding connection between the inner liner and the collar allows for a certain degree of displacement adjustment, enhancing assembly adaptability. The oil injection hole facilitates maintenance and extends the lubrication cycle. The reinforcing rod improves the overall structural strength and deformation resistance of the lifting ring.

[0007] Preferably, a base is fixedly connected to the outer wall below the collar, a sleeve is fixedly connected to the outer wall of the locking plate, a tension spring is fixedly connected to the inner wall of the sleeve, a locking rod is slidably connected to the inner wall of the sleeve, and a buffer assembly is fixedly connected to the outer wall below the base. The elastic locking mechanism uses the restoring force of the elastic element to realize the automatic reset and locking of the locking rod, which is simple to operate. The buffer assembly isolates and reduces the vibration and noise transmitted from the suspension system, thereby improving the smoothness and comfort of the vehicle ride.

[0008] Preferably, the outer wall of the arc-shaped plate has a fixing hole, one end of the tension spring is fixedly connected to the inner wall of the sleeve, and the other end of the tension spring is fixedly connected to the outer wall of the locking rod located inside the sleeve. The locking rod is inserted into the fixing hole on the outer wall away from the sleeve. The outer wall of the reinforcing rod is slidably connected to the inner wall of the fixing groove. The outer wall of the ball has a groove, and the outer wall of the bushing is rotatably connected to the inner wall of the ball. The outer wall of the bushing has a groove for matching the ball. The elastic plug-in locking mechanism ensures the safety of the connection, while the operation is quick and convenient. The sliding fit between the reinforcing rod and the fixing groove enhances the guiding and limiting effect on the liner. The improved contact between the rolling element and the bushing reduces contact stress, reduces wear, and improves lubrication, further ensuring long-term performance.

[0009] Preferably, the buffer assembly includes a telescopic rod, and a buffer spring is sleeved on the outside of the telescopic rod. Both ends of the telescopic rod and the buffer spring are fixedly connected to the base. The buffer structure can buffer and attenuate impact loads from different directions. The telescopic rod ensures the linearity and stability of the movement, while the buffer spring provides good elastic buffering. The two work together to improve the shock absorption effect and the fatigue resistance of the components.

[0010] (III) Beneficial Effects

[0011] This invention provides an aluminum shock absorber ring with an embedded self-lubricating bushing. It has the following advantages:

[0012] (i) The shock absorber aluminum ring with embedded self-lubricating bushing converts the sliding friction of the traditional structure into rolling friction by setting a multi-stage rolling friction pair composed of balls and bushings in the inner liner. This reduces the frictional resistance and wear during operation. Combined with the oil injection hole, lubricant can be added to continuously form a lubricating film, achieving a self-lubricating effect. This ensures the smoothness of force and motion transmission, reduces the wear rate of key components, thereby extending the service life of the entire shock absorber ring and reducing maintenance needs and frequency.

[0013] (II) The shock absorber aluminum lifting ring with embedded self-lubricating bushing is composed of an arc plate, a locking plate, a tension spring and a locking rod, which allows the inner liner assembly that needs to be replaced to be opened for replacement or maintenance without tools. The operation is simple and maintainability is improved. At the same time, the spring-driven automatic locking mechanism ensures the reliability of the locking and prevents accidental loosening under severe vibration. In addition, the inner liner and the collar are connected by a sliding fit between a reinforcing rod and a fixing groove. Under the premise of ensuring the correct transmission of force flow, the inner liner can be finely adjusted axially, absorbing the centering error and thermal stress, avoiding assembly damage and improving adaptability and reliability.

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.

[0020] Please see Figure 1-4 This utility model provides a technical solution for a shock absorber aluminum lifting ring with an embedded self-lubricating bushing, including: a lifting ring assembly 2, a collar 21 is provided inside the lifting ring assembly 2, a reinforcing rod 25 is fixedly connected to the inner wall of the collar 21, a locking plate 27 and an arc plate 26 are rotatably connected to the outer wall of the collar 21 via a hinge, an inner liner 22 is slidably connected inside the collar 21, a fixing groove 28 is opened on the outer wall of the inner liner 22, an annular groove is opened on the inner wall of the inner liner 22, a ball bearing 24 is rotatably connected to the inner wall of the groove, a bushing 23 is rotatably connected to the outer wall of the ball bearing 24, and an oil injection hole 29 is opened on the outer wall of the bushing 23.

[0021] A base 210 is fixedly connected to the outer wall below the collar 21, a sleeve 211 is fixedly connected to the outer wall of the locking plate 27, a tension spring 212 is fixedly connected to the inner wall of the sleeve 211, a locking rod 213 is slidably connected to the inner wall of the sleeve 211, and a buffer assembly 1 is fixedly connected to the outer wall below the base 210.

[0022] The outer wall of the arc plate 26 has a fixing hole. One end of the tension spring 212 is fixedly connected to the inner wall of the sleeve 211. The other end of the tension spring 212 is fixedly connected to the outer wall of the locking rod 213 located inside the sleeve 211. The locking rod 213 is inserted into the fixing hole away from the outer wall of the sleeve 211. The outer wall of the reinforcing rod 25 is slidably connected to the inner wall of the fixing groove 28. The outer wall of the ball 24 has a groove. The outer wall of the bushing 23 is rotatably connected to the inner wall of the ball 24. The outer wall of the bushing 23 has a groove that matches the ball 24.

[0023] The buffer assembly 1 includes a telescopic rod 12, and a buffer spring 11 is sleeved on the outside of the telescopic rod 12. Both ends of the telescopic rod 12 and the buffer spring 11 are fixedly connected to the base 210.

[0024] When in use, connect this device to the external equipment. When the shock absorber aluminum ring is working, its main function is to connect and transmit the force and motion between the shock absorber and the vehicle body, while realizing buffering, shock absorption and self-lubrication.

[0025] When the shock absorber shaft passes through and connects to the bushing 23 inside the eyelet assembly 2, force and motion are transmitted. When the vehicle vibrates and rotates relative to each other during driving, the inner hole of the bushing 23 interacts with the shock absorber shaft. The outer wall of the bushing 23 and the ball 24, as well as the ball 24 and the annular groove of the inner liner 22, form a multi-stage rolling friction pair, which converts traditional sliding friction into rolling friction, reducing frictional resistance and wear. The grease stored in the contact area between the bushing 23 and the ball 24, as well as the lubricant replenished through the oil injection hole 29, can continuously form a lubricating film, achieving long-term self-lubrication, ensuring smooth movement and extending the service life of the components.

[0026] During installation and maintenance, the arc plate 26 and locking plate 27 can be rotated and opened around the hinge point, facilitating the insertion or removal of the inner liner 22 and its internal bushings 23 and balls 24 into or from the collar 21. After closing, the locking rod 213 automatically engages in the fixing hole on the arc plate 26 under the preload of the tension spring 212, achieving quick release and locking, preventing accidental opening during vibration. The sliding fit between the reinforcing rod 25 and the fixing groove 28 on the inner liner 22 not only restricts the circumferential rotation of the inner liner 22, ensuring the correct force transmission path, but also allows for necessary axial fine-tuning or floating to accommodate installation errors and thermal expansion and contraction, avoiding assembly stress. The sleeve 211 provides installation and sliding for the locking rod 213.

[0027] After the shock absorber initially absorbs the impact and vibration from the road surface, the residual force is transmitted to the vehicle body through the aluminum collar. The buffer assembly 1 is a key component for suppressing these residual vibrations and impacts. When the buffer spring 11 is compressed or stretched, it absorbs and stores energy through its elastic deformation and then slowly releases it, thereby dissipating and buffering the impact force. The telescopic rod 12 provides guidance for the buffer spring 11, ensuring that it deforms stably along the axis, preventing instability, and bearing the main tensile and compressive loads. This buffer system can effectively filter out high-frequency fine vibrations and improve ride comfort. The collar 21 can be fixedly connected to the buffer assembly 1 through the base 210.
