Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, and in particular to a novel shock absorber. Background Technology

[0002] Shock absorbers are important components of a car's suspension system, primarily used to buffer and reduce vehicle vibrations during driving, reduce road noise, protect the shock absorber suspension system, and extend its service life. When cornering or driving on bumpy roads, shock absorbers also improve vehicle stability and prevent damage to the shock absorber spring seals caused by excessive bumps. The car stabilizer bar is usually installed horizontally along the side of the vehicle body, parallel to the ground. Its main function is to suppress body roll and improve vehicle stability when cornering. The shock absorber is fitted onto the stabilizer bar and fixed to the car bracket with special clamps. This installation method ensures that the shock absorber remains stable during vehicle operation while effectively transmitting and distributing the load borne by the stabilizer bar.

[0003] In existing technologies, shock absorbers are usually made of a single rubber material. However, shock absorbers made of a single rubber material are easily affected by factors such as temperature changes and environmental pollution during long-term use, which leads to a decrease in their elasticity and a weakening of their shock absorption effect. Furthermore, shock absorbers are more prone to damage due to fatigue and stress concentration during long-term use, resulting in increased replacement frequency and higher maintenance costs. Therefore, a new type of shock absorber is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In order to address the technical problem that existing shock absorbers made of a single rubber material are easily affected by factors such as temperature changes and environmental pollution during long-term use, resulting in a decrease in their elasticity and increased frequency of replacement due to fatigue and stress concentration, this application provides a novel shock absorber.

[0005] The novel shock absorber proposed in this utility model includes a shock absorber body with a cutout, a through hole at the center of the shock absorber body, and the shock absorber body includes a coating, an inner layer, a middle layer and an outer layer.

[0006] The damping block body has an internal reinforcement mechanism, which includes reinforcing ribs. The reinforcing ribs are made of aluminum alloy to enhance the torsional stiffness and fatigue strength of the damping block body.

[0007] Preferably, the coating is applied to the inner wall of the arc-shaped groove of the inner layer, the coating material is polytetrafluoroethylene, and the inner layer material is EPDM rubber.

[0008] Through the above technical solution, the inner layer is a semi-circular arch-rectangular composite structure, consisting of an arc-shaped part and a square part. The arc grooves of both are semi-circular and concentrically arranged, forming the through hole of the damping block body. A coating is applied inside the arc groove, and the coating contacts the outer surface of the damping rod, reducing the friction coefficient between the inner layer and the stabilizer rod, reducing wear and abnormal noise. The material of the coating is polytetrafluoroethylene (PTFE). The chemical stability and wide temperature range adaptability of PTFE ensure its long-term reliability under complex working conditions. The inner layer, as the basic support layer of the damping block body, bears the main compressive and torsional forces. The material of the inner layer is EPDM rubber, which has excellent heat resistance, ozone resistance, and aging resistance.

[0009] Preferably, the intermediate layer is bonded to the outer surface of the inner layer, and the intermediate layer is made of natural rubber.

[0010] Through the above technical solution, the intermediate layer is also a semi-circular arch-rectangular composite structure. Its square part and arc part are completely bonded to the outer surface of the corresponding part of the inner layer through vulcanization bonding process to form a composite structure. The intermediate layer provides additional elasticity and cushioning. The material of the intermediate layer is natural rubber, which has high elasticity, low hysteresis loss and excellent mechanical properties. It mainly provides elastic support and energy dissipation function under dynamic load. Through the synergistic effect with the inner layer, the comprehensive cushioning performance and dynamic response capability of the damping block body are significantly improved.

[0011] Preferably, the outer layer is bonded to the outer surface of the intermediate layer, and the material of the outer layer is nitrile rubber.

[0012] Through the above technical solution, the outer layer is also a semi-circular arch-rectangular composite structure. Its square part and arc part are completely bonded to the outer surface of the corresponding part of the middle layer through a vulcanization bonding process to form a composite structure. The outer layer is the outermost protective layer. The material of the outer layer is nitrile rubber, which has excellent oil and solvent resistance, prevents external chemical corrosion, and provides good mechanical strength and wear resistance to protect the internal structure.

[0013] Preferably, the reinforcing mechanism further includes a placement groove, which is formed inside the intermediate layer, and a spring is disposed inside the placement groove.

[0014] Through the above technical solution, the placement grooves are respectively opened inside the square and arc-shaped parts of the intermediate layer, dividing the intermediate layer into four independent structural units, as shown in the attached drawings of the instruction manual. Each part and the placement groove thereon are injection molded. After the two ends of the spring are coated with epoxy resin adhesive, they are embedded in the placement groove and cured and bonded. Finally, the four structural units are spliced ​​and fixed with adhesive to form a complete intermediate layer. The spring in the intermediate layer provides additional elastic support and further buffers high-frequency vibration. Its material can be silicon manganese spring steel, which has excellent fatigue strength and anti-relaxation performance.

[0015] Preferably, the bottom outer surface of the reinforcing rib is fixedly bonded to the outer surface groove of the inner layer, and the top outer surface of the reinforcing rib is fixedly bonded to the inner sidewall groove of the intermediate layer.

Its bottom outer surface is embedded in the groove of the inner layer's outer surface, and its top outer surface is embedded in the groove of the inner sidewall of the middle layer. The groove is pre-coated with epoxy resin adhesive. The reinforcing rib is fixedly bonded to the inner layer and the middle layer through the embedding process. The isosceles trapezoidal design ensures a tight fit between the reinforcing rib and the groove, avoiding loosening and displacement. The reinforcing rib can achieve uniform force transmission, avoid stress concentration, and extend service life. Its material is aluminum alloy, which has high strength and lightweight characteristics.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. By setting a coating, inner layer, intermediate layer, and outer layer, the coating contacts the outer surface of the shock absorber rod, reducing the friction coefficient between the inner layer and the stabilizer rod, thus reducing wear and abnormal noise. The inner layer, as the basic support layer of the shock absorber body, bears the main compressive and torsional forces. The intermediate layer provides additional elasticity and cushioning. Together with the inner layer, they significantly improve the overall cushioning performance and dynamic response capability of the shock absorber body. The outer layer, as the outermost protective layer, is made of nitrile rubber, which has excellent oil and solvent resistance, preventing external chemical corrosion, and providing good mechanical strength and wear resistance, protecting the internal structure. This solves the technical problem in the existing technology where shock absorbers usually use a single rubber material, but shock absorbers made of a single rubber material are easily affected by factors such as temperature changes and environmental pollution during long-term use, leading to a decrease in their elasticity and a weakening of the shock absorption effect.

[0019] 2. By setting up a reinforcement mechanism, the torsional stiffness and fatigue strength of the damping block body are enhanced. The spring in the middle layer provides additional elastic support, further buffering high-frequency vibrations. The material can be silicon manganese spring steel, which has excellent fatigue strength and anti-relaxation performance. The isosceles trapezoidal design ensures a tight fit between the reinforcing rib and the groove, avoiding loosening and displacement. The reinforcing rib can achieve uniform force transmission, avoid stress concentration, and extend service life. The material is aluminum alloy, which has high strength and lightweight characteristics. This solves the technical problem in the existing technology that the damping block is more likely to be damaged due to fatigue and stress concentration during long-term use, resulting in increased replacement frequency and maintenance costs.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1 - Figure 6, a new type of shock absorber block, including a shock absorber block body 1 with a cutout, a through hole 11 at the center of the shock absorber block body 1, and the shock absorber block body 1 including a coating 2, an inner layer 21, a middle layer 3 and an outer layer 4.

[0029] To reduce the coefficient of friction between the inner layer 21 and the stabilizer bar, coating 2 is applied to the inner wall of the arc-shaped groove of the inner layer 21. The material of coating 2 is polytetrafluoroethylene (PTFE), and the material of the inner layer 21 is EPDM rubber. The inner layer 21 has a semi-circular arch-rectangular composite structure, consisting of an arc-shaped part and a square part. The arc-shaped grooves of both are semi-circular and concentrically arranged, forming the through hole 11 of the damper body 1. Coating 2 is applied inside the arc-shaped groove. Coating 2 contacts the outer surface of the damper bar, reducing the coefficient of friction between the inner layer 21 and the stabilizer bar, reducing wear and abnormal noise. The material of coating 2 is PTFE. The chemical stability and wide temperature range adaptability of PTFE ensure its long-term reliability under complex working conditions. The inner layer 21 serves as the basic support layer of the damper body 1, bearing the main compressive and torsional forces. The material of the inner layer 21 is EPDM rubber, which has excellent heat resistance, ozone resistance, and aging resistance.

[0030] To enhance the overall buffering performance and dynamic response capability of the damping block body 1, the intermediate layer 3 is bonded to the outer surface of the inner layer 21. The intermediate layer 3 is made of natural rubber and also has a semi-circular arch-rectangular composite structure. Its square and arc-shaped parts are completely bonded to the corresponding outer surfaces of the inner layer 21 through a vulcanization bonding process to form a composite structure. The intermediate layer 3 provides additional elasticity and buffering. Because the intermediate layer 3 is made of natural rubber, it has high elasticity, low hysteresis loss and excellent mechanical properties. It mainly provides elastic support and energy dissipation under dynamic loads. Through its synergistic effect with the inner layer 21, it significantly enhances the overall buffering performance and dynamic response capability of the damping block body 1.

[0031] To prevent corrosion from external chemicals, the outer layer 4 is bonded to the outer surface of the middle layer 3. The outer layer 4 is made of nitrile rubber and also has a semi-circular arch-rectangular composite structure. Its square and arc-shaped parts are completely bonded to the corresponding parts of the outer surface of the middle layer 3 through a vulcanization bonding process to form a composite structure. As the outermost protective layer, the outer layer 4 is made of nitrile rubber, which has excellent oil and solvent resistance, prevents corrosion from external chemicals, and provides good mechanical strength and wear resistance to protect the internal structure.

[0032] By setting a coating 2, an inner layer 21, a middle layer 3, and an outer layer 4, the coating 2 contacts the outer surface of the damping rod, reducing the friction coefficient between the inner layer 21 and the stabilizer bar, thus reducing wear and abnormal noise. The inner layer 21 serves as the basic support layer of the damping block body 1, bearing the main compressive and torsional forces. The middle layer 3 provides additional elasticity and cushioning, and works synergistically with the inner layer 21 to significantly improve the comprehensive cushioning performance and dynamic response capability of the damping block body 1. The outer layer 4 serves as the outermost protective layer. The material of the outer layer 4 is nitrile rubber, which has excellent oil and solvent resistance, preventing external chemical corrosion, and providing good mechanical strength and wear resistance, protecting the internal structure. This solves the technical problem in the prior art that damping blocks usually use a single rubber material, but damping blocks made of a single rubber material are easily affected by factors such as temperature changes and environmental pollution during long-term use, leading to a decrease in their elasticity and a weakening of the damping effect.

[0033] In order to enhance the torsional stiffness and fatigue strength of the damping block body 1, a reinforcement mechanism is provided inside the damping block body 1. The reinforcement mechanism includes a reinforcing rib 6, which is made of aluminum alloy to enhance the torsional stiffness and fatigue strength of the damping block body 1.

[0034] To further buffer high-frequency vibrations, the reinforcement mechanism also includes placement grooves 5, which are formed inside the intermediate layer 3. Springs 51 are installed in the placement grooves 5. The placement grooves 5 are respectively formed inside the square and arc-shaped parts of the intermediate layer 3, dividing the intermediate layer 3 into four independent structural units, as shown in the attached drawings of the instruction manual. Each part and the placement grooves 5 thereon are injection molded. After the two ends of the springs 51 are coated with epoxy resin adhesive, they are embedded in the placement grooves 5 and cured and bonded. Finally, the four structural units are spliced ​​and fixed with adhesive to form a complete intermediate layer 3. The springs 51 in the intermediate layer 3 provide additional elastic support to further buffer high-frequency vibrations. The material can be silicon manganese spring steel 51, which has excellent fatigue strength and anti-relaxation performance.

[0035] To achieve uniform force transmission and avoid stress concentration, the bottom outer surface of the reinforcing rib 6 is fixedly bonded to the groove on the outer surface of the inner layer 21, and the top outer surface of the reinforcing rib 6 is fixedly bonded to the groove on the inner sidewall of the intermediate layer 3. The cross-section of the reinforcing rib 6 is an isosceles trapezoid, with its bottom outer surface embedded in the groove on the outer surface of the inner layer 21 and its top outer surface embedded in the groove on the inner sidewall of the intermediate layer 3. The grooves are pre-coated with epoxy resin adhesive. The reinforcing rib 6 is fixedly bonded to the inner layer 21 and the intermediate layer 3 respectively through the embedding process. The isosceles trapezoidal design ensures a tight fit between the reinforcing rib 6 and the groove, avoiding loosening and displacement. The reinforcing rib 6 can achieve uniform force transmission, avoid stress concentration, and extend service life. Its material is aluminum alloy, which has high strength and lightweight characteristics.

[0036] By setting up a reinforcement mechanism to enhance the torsional stiffness and fatigue strength of the damping block body 1, the spring 51 in the intermediate layer 3 provides additional elastic support to further buffer high-frequency vibrations. Its material can be silicon manganese spring steel 51, which has excellent fatigue strength and anti-relaxation performance. The isosceles trapezoidal design ensures a tight fit between the reinforcing rib 6 and the groove, avoiding loosening and displacement. The reinforcing rib 6 can achieve uniform force transmission, avoid stress concentration, and extend service life. Its material is aluminum alloy, which has high strength and lightweight characteristics. This solves the technical problem in the prior art that the damping block is more likely to be damaged due to fatigue and stress concentration during long-term use, resulting in increased replacement frequency and maintenance costs.

[0037] Working principle: When making the damping block body 1, EPDM rubber granules are heated to a plasticized state and injected into molds with semi-circular arch and rectangular structure cavities respectively. After cooling and solidification, they are demolded to form the arc-shaped part and square part of the inner layer 21. Polytetrafluoroethylene coating 2 is sprayed on the inner wall of the arc groove of the arc-shaped part and the square part. The coating 2 has a uniform thickness and is then heated and cured to ensure that the coating 2 is firmly bonded to the inner layer 21 substrate. The arc-shaped part and the square part are spliced ​​and fixed by adhesive to form a complete inner layer 21-coating 2 composite structure, ensuring that the arc grooves are concentrically aligned to form the through hole 11 of the damping block body 1.

[0038] The middle layer 3 is designed as four independent structural units; please refer to the instruction manual for details. Figure 6 The unit consists of two arc-shaped and two square parts, which are injection molded using an injection mold. Each unit has a placement groove 5 inside for the subsequent embedding of the spring 51. The two ends of the spring 51 are coated with epoxy resin adhesive, embedded in the placement groove 5 and cured to ensure a firm bond between the spring 51 and the intermediate layer 3 structural unit. Epoxy resin adhesive is applied to the grooves on the outer surface of the inner layer 21 and the inner sidewall of the intermediate layer 3. The aluminum alloy reinforcing rib 6 is embedded in the groove and fixed by the embedding process. The isosceles trapezoidal cross-section design of the reinforcing rib 6 ensures a tight fit with the groove and prevents loosening. The square and arc-shaped parts are completely bonded to the outer surface of the corresponding parts of the inner layer 21 by a vulcanization bonding process to form a composite structure of intermediate layer 3 and inner layer 21.

[0039] The outer layer 4 is also injection molded by injection molding. Its square part and arc part are completely bonded to the outer surface of the corresponding part of the middle layer 3 by vulcanization bonding process, and finally form a complete shock absorber body 1.

[0040] A cut is made in the square part of the damping block body 1. The cut depth extends through the outer layer 4, the middle layer 3 and the inner layer 21. The cut width is designed according to the diameter of the stabilizer bar and the installation requirements. The cut edges are chamfered to avoid scratching the stabilizer bar during installation. Check whether the cut and through hole 11 of the damping block body 1 meet the design requirements and ensure that the cut width matches the diameter of the stabilizer bar.

[0041] Clean the surface of the stabilizer bar to ensure it is free of oil and impurities to avoid affecting the contact performance between the coating 2 and the stabilizer bar. Use a special tool to open the cut of the shock absorber body 1 so that the diameter of the through hole 11 is slightly larger than the diameter of the stabilizer bar. Insert the stabilizer bar into the through hole 11 of the shock absorber body 1 through the cut, ensuring that the stabilizer bar is in contact with the polytetrafluoroethylene surface of the inner layer 21 coating 2. Remove the special tool and allow the cut to return to its original position naturally. Clamp the stabilizer bar and fix the shock absorber body 1 to the bracket of the car suspension system with bolts or clamps, ensuring that the outer layer 4 of the shock absorber body 1 is completely in contact with the bracket to prevent loosening.

[0042] Check the fit clearance between the damping block body 1 and the stabilizer bar to ensure there is no abnormal friction. Conduct dynamic tests to verify whether the damping performance and torsional stiffness of the damping block meet the design requirements.

[0043] The electronic devices, their power supply methods, and control methods described in this article are all existing technologies with mature applications. Therefore, they will only be briefly explained here without further elaboration.
