Description

Technical Field

[0001] This application belongs to the technical field of motorcycle shock absorbers, and particularly relates to a motorcycle front fork shock absorber. Background Technology

[0002] Shock absorbers are widely used in vehicles such as cars and motorcycles to dampen vibrations during driving and improve ride smoothness. Motorcycle rear shock absorbers can quickly dampen impacts and vibrations caused by vehicle weight, load, and various road conditions, greatly improving the shock absorption performance of motorcycles and enhancing the stability and safety of motorcycle riding.

[0003] A Chinese patent with publication number CN115214832B discloses a shock-absorbing structure for a motorcycle and a motorcycle. The shock-absorbing structure includes a metal plate capable of elastic deformation, one end of which is disposed on one of the motorcycle body and a first wheel connecting rod. The motorcycle body and the first wheel connecting rod are pivotally connected about a first pivot axis. The first wheel connecting rod is pivotally connected to a front wheel or a rear wheel, and its pivot axis is parallel to the first pivot axis. The direction in which the metal plate extends is perpendicular to the first pivot axis. The other of the motorcycle body and the first wheel connecting rod is a limiting unit. The limiting unit has a first accommodating space that allows the opposite end of the metal plate to extend out and is adapted to the metal plate.

[0004] When the aforementioned invention passes over an obstacle or travels from an obstacle to a flat surface, it causes the first wheel connecting rod to rotate relative to the vehicle body around the first pivot axis, resulting in elastic deformation of the metal plate relative to the limiting unit, thus providing cushioning for the rotation of the first wheel connecting rod relative to the vehicle body. However, the invention has poor dustproof performance; dust entering the shock absorber will damage the oil seal, causing oil leakage and affecting the shock absorption effect. Utility Model Content

[0005] The purpose of this application is to address the aforementioned technical problems by providing a motorcycle front fork shock absorber that has excellent dustproof performance, preventing dust from affecting the shock absorber and ensuring the shock absorption effect.

[0006] This application provides a motorcycle front fork shock absorber, including a shock absorber body, the shock absorber body comprising:

[0007] The shock-absorbing oil cylinder includes a shock-absorbing spring, a damper, a piston rod, a dustproof screen, and a sealing assembly;

[0008] Front fork bracket;

[0009] Shock-absorbing metal plates are placed on both sides of the front fork bracket;

[0010] The shock-absorbing spring is connected to the damper, the piston rod is slidably connected to the shock-absorbing oil cylinder, and the dustproof net and sealing assembly are both placed inside the shock-absorbing oil cylinder.

[0011] In this technical solution, a shock absorber cylinder, a front fork bracket, and a shock absorber metal plate are installed in the shock absorber body. The shock absorber cylinder contains a shock absorber spring, a damper, a piston rod, a dustproof net, and a sealing assembly. The shock absorber spring and the damper are connected, and the piston rod and the shock absorber cylinder are slidably connected. The dustproof net and the sealing assembly are both placed inside the shock absorber cylinder. The shock absorber cylinder protects the internal oil seal through its internal dustproof net and sealing assembly, preventing the oil seal from being invaded by external dust and preventing oil leakage due to dust intrusion, which would affect the shock absorption effect. When the motorcycle rolls over obstacles, the piston rod, in conjunction with the shock absorber spring, can effectively reduce the impact of vibration. The damper can prevent the shock absorber spring from constantly rebounding, making the shock absorption effect of the shock absorber body more stable. The shock absorber metal plate is placed on both sides of the front fork bracket. When the motorcycle is affected by vibration, the shock absorber metal plate undergoes elastic deformation relative to the front fork bracket, which can effectively provide cushioning for the motorcycle body and further improve the shock absorption effect of the shock absorber body.

[0012] Furthermore, the shock absorber body is also equipped with a dustproof baffle;

[0013] The dust baffle is connected to the front fork bracket.

[0014] In this technical solution, by setting a dust baffle on the shock absorber body and connecting the dust baffle to the fork bracket, the dust baffle can effectively block dust, reduce the probability of dust and impurities entering the shock absorber body, ensure the working effect of the shock absorber body, and prevent the shock absorber from leaking oil due to dust intrusion.

[0015] Furthermore, the sealing assembly includes:

[0016] Cap;

[0017] A sealing rubber ring is fitted between the sealing cap and the sealing ring.

[0018] The sealing rubber ring is in close contact with the inner wall of the shock-absorbing oil cylinder.

[0019] In this technical solution, by setting a cover and a sealing rubber ring in the sealing assembly, and the sealing rubber ring and the cover are sleeved together, and the sealing rubber ring is in close contact with the inner wall of the shock-absorbing oil cylinder, after some fine dust enters into the shock-absorbing oil cylinder, the cover and the sealing rubber ring can effectively increase the sealing performance of the shock-absorbing oil cylinder, prevent fine dust and impurities from entering the shock-absorbing oil cylinder, effectively protect the oil seal, and enable the shock-absorbing oil cylinder to work stably.

[0020] Furthermore, a dustproof cloth is attached to the surface of the shock-absorbing oil cylinder.

[0021] In this technical solution, a dustproof cloth is attached to the surface of the shock-absorbing oil cylinder. The dustproof cloth has excellent dustproof effect and can prevent dust from adhering to the surface of the shock-absorbing oil cylinder, further reducing the probability of dust entering the interior of the shock-absorbing oil cylinder, thereby ensuring the shock absorption effect of the shock absorber body.

[0022] Furthermore, the shock-absorbing metal plate is made of spring steel plate.

[0023] In this technical solution, by setting the material of the metal plate to spring steel plate, which has excellent elasticity, the elastic deformation degree of the shock-absorbing metal plate is improved. The shock-absorbing metal plate can provide a greater degree of buffering for the vehicle body and further reduce the impact of vibration on the front fork bracket.

[0024] Furthermore, the inner wall of the shock-absorbing oil cylinder is covered with a wear-resistant layer.

[0025] In this technical solution, by covering the inner wall of the shock-absorbing cylinder with a wear-resistant layer, the wear-resistant layer has excellent wear resistance. When the piston rod slides inside the shock-absorbing cylinder, it can prevent the wear-resistant layer from being worn quickly by the piston rod, thereby extending the service life of the shock-absorbing cylinder.

[0026] The beneficial effects of this application are:

[0027] 1. The shock absorber cylinder protects the internal oil seal with its internal dustproof mesh and sealing components, preventing external dust from entering the oil seal and preventing oil leakage due to dust intrusion, which would affect the shock absorption effect. When the motorcycle rolls over obstacles, the piston rod, together with the shock absorber spring, can effectively reduce the impact of vibration, while the damper can prevent the shock absorber spring from constantly rebounding, making the shock absorption effect of the shock absorber body more stable.

[0028] 2. The shock-absorbing metal plates are placed on both sides of the front fork bracket. The shock-absorbing metal plates are made of spring steel plates. When the motorcycle is affected by vibration, the shock-absorbing metal plates undergo elastic deformation relative to the front fork bracket, which can effectively provide cushioning for the motorcycle body and further improve the shock absorption effect of the shock absorber body.

[0029] 3. The cap and sealing rubber ring can effectively increase the sealing performance of the shock-absorbing oil cylinder, prevent fine dust and impurities from entering the shock-absorbing oil cylinder, effectively protect the oil seal, and enable the shock-absorbing oil cylinder to work stably.

[0035] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0036] Example 1:

[0037] like Figure 1 and Figure 2 As shown, this application embodiment provides a motorcycle front fork shock absorber, including a shock absorber body 100, the shock absorber body 100 comprising:

[0039] Front fork bracket 110;

[0040] Shock-absorbing metal plates 120 are placed on both sides of the front fork bracket 110;

[0041] The shock-absorbing spring 210 is connected to the damper 220, the piston rod 230 is slidably connected to the shock-absorbing oil cylinder 200, and the dustproof net 240 and the sealing assembly 250 are both placed inside the shock-absorbing oil cylinder 200.

[0042] By incorporating a shock absorber cylinder 200, a fork bracket 110, and a shock absorber metal plate 120 within the shock absorber body 100, and by installing a shock absorber spring 210, a damper 220, a piston rod 230, a dustproof net 240, and a sealing assembly 250 within the shock absorber cylinder 200, the shock absorber spring 210 and the damper 220 are connected, and the piston rod 230 and the shock absorber cylinder 200 are slidably connected. The dustproof net 240 and the sealing assembly 250 are both located inside the shock absorber cylinder 200. The shock absorber cylinder 200 protects the internal oil seal through its internal dustproof net 240 and sealing assembly 250, preventing the oil seal from being damaged by external contamination. To prevent dust from entering and causing oil leakage in the shock absorber cylinder 200, thus affecting the shock absorption effect, when the motorcycle rolls over obstacles, the piston rod 230, together with the shock absorber spring 210, can effectively reduce the impact of vibration. The damper 220 can prevent the shock absorber spring 210 from constantly rebounding, making the shock absorption effect of the shock absorber body 100 more stable. The shock absorber metal plate 120 is placed on both sides of the front fork bracket 110. When the motorcycle is affected by vibration, the shock absorber metal plate 120 undergoes elastic deformation relative to the front fork bracket 110, which can effectively provide cushioning for the body and further improve the shock absorption effect of the shock absorber body 100.

[0043] Furthermore, the shock absorber body 100 is also provided with a dustproof baffle 130;

[0044] The dust baffle 130 is connected to the front fork bracket 110.

[0045] By setting a dust baffle 130 on the shock absorber body 100 and connecting the dust baffle 130 with the fork bracket 110, the dust baffle 130 can effectively block dust, reduce the probability of dust and impurities entering the shock absorber body 100, ensure the working effect of the shock absorber body 100, and prevent the shock absorber from leaking oil due to dust intrusion.

[0046] Furthermore, the sealing assembly 250 includes:

[0047] 251 caps;

[0048] A sealing rubber ring 252 is fitted between the sealing cap 251;

[0049] The sealing rubber ring 252 is in close contact with the inner wall of the shock-absorbing oil cylinder 200.

[0050] By setting a cover 251 and a sealing rubber ring 252 in the sealing assembly 250, and fitting the sealing rubber ring 252 and the cover 251 together, and the sealing rubber ring 252 being in close contact with the inner wall of the shock-absorbing oil cylinder 200, after some fine dust enters the shock-absorbing oil cylinder 200, the cover 251 and the sealing rubber ring 252 can effectively increase the sealing performance of the shock-absorbing oil cylinder 200, preventing fine dust and impurities from entering the shock-absorbing oil cylinder 200, effectively protecting the oil seal, and enabling the shock-absorbing oil cylinder 200 to work stably.

[0051] Example 2:

[0052] like Figure 1 and Figure 2 As shown, this application embodiment provides a motorcycle front fork shock absorber, which, in addition to the technical solutions of the above embodiments, also has the following technical features. A dustproof cloth is attached to the surface of the shock-absorbing oil cylinder 200.

[0053] By attaching a dustproof cloth to the surface of the shock absorber cylinder 200, the dustproof cloth has an excellent dustproof effect and can prevent dust from adhering to the surface of the shock absorber cylinder 200, further reducing the probability of dust entering the interior of the shock absorber cylinder 200, thereby ensuring the shock absorption effect of the shock absorber body 100.

[0054] Furthermore, the shock-absorbing metal plate 120 is made of spring steel plate.

[0055] By setting the material of the metal plate to spring steel, which has excellent elasticity, the elastic deformation of the shock-absorbing metal plate 120 is improved. The shock-absorbing metal plate 120 can provide a greater degree of cushioning for the vehicle body, further reducing the impact of vibration on the front fork bracket 110.

[0056] Furthermore, the inner wall of the shock-absorbing oil cylinder 200 is covered with a wear-resistant layer.

[0057] By covering the inner wall of the shock-absorbing cylinder 200 with a wear-resistant layer, which has excellent wear resistance, the piston rod 230 can slide inside the shock-absorbing cylinder 200, thus preventing the wear-resistant layer from being worn quickly by the piston rod 230, thereby extending the service life of the shock-absorbing cylinder 200.
