Description

Technical Field

[0001] This utility model relates to the field of shock absorbers, and in particular to an adjustable shock absorber for two-wheeled vehicles. Background Technology

[0002] Shock absorbers are the core components of a two-wheeled vehicle's suspension system. They absorb road impacts through springs and damping systems, reducing vibrations transmitted to the vehicle body and occupants.

[0003] Traditional shock absorbers have an adjustable structure in the connecting channel between the cylinder and the piston cylinder to adjust the diameter of the connecting channel. However, the oil flow between the cylinder and the piston cylinder is only through this single connecting channel. Adjusting the diameter of this connecting channel can adjust both the compression damping and the rebound damping of the shock absorber. This makes it impossible to adjust the compression damping and rebound damping separately, thus failing to meet different adjustment requirements. Utility Model Content

Detailed Implementation

[0027] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0028] like Figures 1-6 As shown, an adjustable shock absorber for a two-wheeled vehicle includes a piston cylinder 1 and a piston rod 2; a shock-absorbing spring 7 is disposed between the piston cylinder 1 and the piston rod 2; and further includes:

[0029] Side seat 9, the side seat 9 is fixedly installed to one side of the bottom of piston cylinder 1, and cylinder 8 is fixedly installed on the side seat 9 through connecting plate 16;

[0030] The first guide channel 11 and the second guide channel 13 are connected at both ends to one side of the cylinder 8 and the bottom of the piston cylinder 1, respectively; the two ends of the second guide channel 13 are also connected to one side of the cylinder 8 and the bottom of the piston cylinder 1, respectively.

[0031] A first check valve 12 and a second check valve 14 are respectively installed in the first flow channel 11 and the second flow channel 13.

[0032] The adjustment assembly 10 consists of two components, with the two adjustment assemblies 10 respectively located at one end of the first guide channel 11 near the piston cylinder 1 and the other end of the second guide channel 13 near the piston cylinder 1.

[0033] In the aforementioned shock absorber, the first one-way valve 12 and the second one-way valve 14 ensure that the first guide channel 11 and the second guide channel 13 can only flow in one direction. Specifically, when the top of the piston rod 2 is subjected to force and moves downward, it compresses the oil in the piston cylinder 1. The oil can only enter the cylinder 8 through the first guide channel 11 and cannot enter the cylinder 8 through the second guide channel 13. When the force on the top of the piston rod 2 decreases or is lost, the oil can only flow back to the piston cylinder 1 through the second guide channel 13 and cannot flow back through the first guide channel 11.

[0034] By limiting the unidirectional flow as described above, and in conjunction with the two adjustment components 10, the flow diameter of the first guide channel 11 and the second guide channel 13 can be adjusted to regulate the compression damping and rebound speed of the shock absorber.

[0035] Adjusting the flow diameter of the first guide channel 11 is used to adjust the oil inlet obstruction of the cylinder 8, thereby adjusting the compression damping. Decreasing the flow diameter of the first guide channel 11 increases the obstruction of oil entering the cylinder 8 through the first guide channel 11, thus increasing the damping of the shock absorber under compression. Conversely, increasing the flow diameter of the first guide channel 11 decreases the obstruction of oil entering the cylinder 8 through the first guide channel 11, thus decreasing the damping of the shock absorber under compression.

[0036] Adjusting the diameter of the second guide channel 13 regulates the obstruction of oil flow from cylinder 8, thereby adjusting the rebound speed of the shock absorber. Decreasing the diameter of the second guide channel 13 increases the resistance to oil flow back into piston cylinder 1, thus slowing down the shock absorber's rebound speed. Increasing the diameter of the second guide channel 13 reduces the resistance to oil flow back into piston cylinder 1, thus increasing the shock absorber's rebound speed.

[0037] like Figure 4 As shown, a floating piston 801 is installed inside the cylinder 8 to separate the oil from the gas. The floating piston 801 divides the cylinder, forming a gas chamber on the left and an oil chamber on the right. One end of the first guide channel 11 and one end of the second guide channel 13 are both connected to the oil chamber. After the oil is compressed in the piston cylinder 1, the hydraulic pressure acts on the floating piston 801 to compress the gas in the gas chamber. When the pressure load is removed, the floating piston 801 is reset by the gas pressure, and the oil is pushed back into the piston cylinder 1.

[0038] like Figures 1-2As shown, a top plate 3 is fixedly installed at the top of the piston rod 2, and a fixed plate 6 is fixedly sleeved on the outer wall of the piston cylinder 1. The two ends of the shock-absorbing spring 7 are respectively connected to the fixed plate 6 and the top plate 3. When the piston rod 2 is subjected to force, the shock-absorbing spring 7 is compressed to provide cushioning.

[0039] like Figures 1-2 As shown, a first connecting frame 4 is fixedly installed above the top plate 3; a second connecting frame 5 is fixedly installed at the bottom of the piston cylinder 1. The entire shock absorber is connected to an external structure at both ends through the first connecting frame 4 and the second connecting frame 5, such as when installed on a two-wheeled motorcycle.

[0040] like Figure 6 As shown, the side seat 9 has two sliding grooves 901 inside, and the two sliding grooves 901 are respectively connected and disposed below the end of the first guide channel 11 near the piston cylinder 1 and below the end of the second guide channel 13 near the piston cylinder 1. The sliding grooves 901 provide a mounting position for the movable gate seat 1005.

[0041] like Figure 6 As shown, the adjustment assembly 10 includes a movable gate seat 1005; the movable gate seat 1005 is slidably installed in the slide groove 901, and the movable gate seat 1005 is connected to a lifting part, and the lifting part is connected to a driving part.

[0042] The lifting unit includes a fixed seat 1003 fixedly installed in the slide groove 901. A stud 1004 is rotatably installed on the fixed seat 1003. The stud 1004 is threadedly connected to a nut seat 1006 fixedly installed on the movable gate seat 1005.

[0043] The drive unit includes two bevel gears 1007; the two bevel gears 1007 are meshed together, one of the bevel gears 1007 is fixed to one end of the stud 1004, and the other bevel gear 1007 is fixedly connected to a rotating shaft 1002, and the rotating shaft 1002 is rotatably mounted in the side seat 9.

[0044] A turning head 1001 is fixedly installed at one end of the rotating shaft 1002 away from the bevel gear 1007. The turning head 1001 is embedded in a hole opened on the side of the side seat 9, and a hexagonal hole 10011 is opened on the turning head 1001.

[0045] The adjustment component 10 operates as follows: an internal hex wrench is inserted into the hexagonal hole 10011, and the hex wrench rotates the turning head 1001, causing the rotating shaft 1002 to rotate. The meshing transmission of the two bevel gears 1007 causes the stud 1004 to rotate. Through the threaded rotation of the stud 1004 and the nut seat 1006, the movable gate seat 1005 is driven to slide in the slide groove 901 to adjust the length of the movable gate seat 1005 extending into the first guide channel 11 or the second guide channel 13, thereby adjusting the flow diameter of the first guide channel 11 and the second guide channel 13.

[0046] The bottom of the side seat 9 is provided with an outer groove 902, and the outer groove 902 is connected to the bottom of the slide groove 901. A sealing plate 15 is installed in the outer groove 902 by screws.

[0047] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
