Abstract
Description
Technical Field
[0001] This utility model relates to the field of shock absorber technology, specifically to a shock absorber for motorcycles with adjustable shock absorption intensity. Background Technology
[0002] Motorcycles, as a common means of transportation, play an important role in people's daily travel, leisure and entertainment, and logistics. During operation, motorcycles inevitably encounter various complex road conditions, such as potholes, bumps, and speed bumps. These conditions cause severe vibrations and impacts, which not only affect riding comfort, causing discomfort for the driver and passengers, but can also damage various components of the motorcycle over time, shortening its lifespan and even affecting driving safety.
[0003] According to announcement number CN 220060353 U, a damping shock absorber for motorcycles includes: a first connecting seat, a second connecting seat, and a shock-absorbing spring. The shock-absorbing spring is disposed between the first connecting seat and the second connecting seat. A damping cylinder is disposed in the inner cavity of the shock-absorbing spring. A threaded rod is fixed to the bottom end of the first connecting seat. The limiting mechanism includes a threaded ring, a rubber ring, multiple limiting grooves, and two limiting components. The rubber ring is fixed to the bottom of the threaded ring. The limiting components are used to limit the threaded ring and the limiting grooves. A pulling mechanism is provided between the two limiting components for sliding the two limiting components.
[0004] This device utilizes a combination of a threaded rod, a limiting mechanism, and a pulling mechanism: this prevents the threaded ring from slipping off the threaded rod due to long-term vibration, thus improving the stability of the shock absorber spring. The pulling mechanism enhances the stability of the limiting component's movement, ensuring it doesn't affect the spring's damping effect. However, the motorcycle shock absorber in this device is designed with a fixed damping strength; its damping performance parameters are determined during manufacturing and cannot be adjusted based on actual usage.

[0028] This utility model provides the following technical solution: Example
[0029] Please see Figure 1-4 This utility model provides a technical solution: a shock absorber for motorcycles with adjustable shock absorption strength, including an outer cylinder 1, an inner cylinder 2 fixedly connected to the inner wall of the outer cylinder 1, a sealing block 3 fixedly connected to the top of the outer cylinder 1, a piston rod 4 provided on the top of the sealing block 3, a piston 5 fixedly connected to the bottom end of the piston rod 4, an adjustment mechanism 6 provided on the surface of the piston rod 4, and a limit mechanism 7 provided on the surface of the piston rod 4 near the top.
[0030] The adjusting mechanism 6 includes a fixed plate 61, which is fixedly connected to the surface of the piston rod 4. Guide rods 62 are symmetrically arranged on the top of the fixed plate 61. Movable plates 63 are fixedly connected to the bottom of the two guide rods 62. Fixed rods 64 are fixedly connected to the bottom of the movable plates 63 in a circular array at equal intervals. First fixed rings 65 are fixedly connected to the bottom of the four fixed rods 64. Shock-absorbing springs 66 are fixedly connected to the bottom of the first fixed rings 65. Second fixed rings 67 are fixedly connected to the top of the outer cylinder 1.
[0031] The top of the sealing block 3 has a hole that matches the piston rod 4, and the surface of the piston rod 4 passes through and slides up and down in the hole, while the surface of the piston 5 slides up and down in connection with the inner wall of the inner cylinder 2.
[0032] The top left and right sides of the fixed plate 61 have holes that match the guide rod 62, and the guide rod 62 is slidably connected to the hole through the surface of the plate and slides up and down. The top of the guide rod 62 is arc-shaped.
[0033] The top of the movable plate 63 has a hole, and the diameter of the hole is larger than the diameter of the piston rod 4. The piston rod 4 is located in the hole on the top of the movable plate 63. The bottom end of the shock-absorbing spring 66 is fixedly connected to the top of the second fixed ring 67. Example
[0034] Please see Figure 5-7 Furthermore, based on Embodiment 1, a limiting mechanism 7 is obtained.
[0035] The limiting mechanism 7 includes a fixed cylinder 71, which is fixedly connected to the surface of the piston rod 4 near the top. An annular groove 72 is provided on the surface of the fixed cylinder 71 near the top. A rotating ring 73 is rotatably connected in the annular groove 72. A rotating cylinder 74 is fixedly connected to the outer ring of the rotating ring 73. A limiting hole 75 is provided at the bottom of the rotating cylinder 74.
[0036] There are three sets of limiting holes 75, which are equally spaced in a circular array at the bottom of the rotating cylinder 74, and the depth of the three limiting holes 75 gradually increases.
[0037] The top end of the guide rod 62 is inserted into the limiting hole 75, and the limiting hole 75 is the corresponding arc shape of the top end of the guide rod 62.
[0038] In actual operation, when this device is in use, the inner cylinder 2 is fixedly connected to the inner wall of the outer cylinder 1, and a sealing block 3 is fixed to the top of the outer cylinder 1. A piston rod 4 is provided on the top of the sealing block 3, and a piston is fixed to the bottom of the piston rod 4. The surface of the piston rod 4 passes through the matching hole opened on the top of the sealing block 3 and can slide up and down, while the surface of the piston slides up and down on the inner wall of the inner cylinder 2. When the motorcycle encounters bumps while riding, the piston rod 4 will be subjected to an upward force and move upward, driving the piston to slide upward in the inner cylinder 2, compressing the gas or liquid in the inner cylinder 2, generating a damping force, and playing a preliminary shock absorption role. The adjusting mechanism 6 is used to adjust the shock absorption intensity. The fixing plate 61 is fixed to the surface of the piston rod 4, and guide rods 62 are symmetrically arranged on the left and right sides of its top. The bottom of the guide rods 62 is fixedly connected to the moving plate 63. The bottom of the movable plate 63 is fixed with four fixed rods 64 in a circular array at equal intervals. The bottom ends of the four fixed rods 64 are fixed with a first fixed ring 65. The bottom of the first fixed ring 65 is fixed with a shock-absorbing spring 66. The bottom end of the shock-absorbing spring 66 is fixed to a second fixed ring 67 on the top of the outer cylinder 1. During the shock absorption process, when the piston rod 4 moves upward, it will drive the fixed plate 61 to move upward together. Since the guide rod 62 passes through the matching hole opened at the top of the fixed plate 61 and can slide up and down, when the fixed plate 61 moves upward, the guide rod 62 moves downward relative to the fixed plate 61, thereby driving the movable plate 63, the fixed rods 64, the first fixed ring 65 and the shock-absorbing spring 66 to move downward, so that the shock-absorbing spring 66 is compressed and generates elastic force, further enhancing the shock absorption effect.
[0039] The limiting mechanism 7 is used to restrict the movement of the guide rod 62, thereby adjusting the compression degree of the damping spring 66 and realizing the adjustment of the damping intensity. The fixed cylinder 71 is fixed to the surface of the piston rod 4 near the top. An annular groove 72 is opened on its surface near the top. A rotating ring 73 is rotatably connected in the annular groove 72. The outer ring of the rotating ring 73 is fixedly connected to the rotating cylinder 74. Three sets of limiting holes 75 are equidistantly distributed in a circular array at the bottom of the rotating cylinder 74, and the depth of the three limiting holes 75 gradually increases. The inner part of the limiting hole 75 is an arc corresponding to the top of the guide rod 62. When it is necessary to adjust the damping intensity, the rotating cylinder 74 is rotated. Since the rotating ring 73 rotates in the annular groove 72, the rotating cylinder 74 can rotate relative to the fixed cylinder 71. The guide rod 62 is inserted into the limiting holes 75 at different depths. When the guide rod 62 is inserted into a shallower limiting hole 75, during the damping process, the guide rod 62 moves downward a greater distance relative to the fixed plate 61, the damping spring 66 is compressed to a greater degree, the generated elastic force is greater, and the damping strength is stronger. When the guide rod 62 is inserted into a deeper limiting hole 75, the guide rod 62 moves downward a smaller distance relative to the fixed plate 61, the damping spring 66 is compressed to a smaller degree, the generated elastic force is smaller, and the damping strength is weaker. In this way, the damping strength can be adjusted.
