Description

Technical Field

[0001] This utility model relates to the field of motorcycle parts technology, and in particular to an adjustable damper. Background Technology

[0002] A titanium ruler is a steering damper on a motorcycle, also known as a "steering stabilizer." Its structure includes a needle, a sleeve, and a pushrod. The function of the titanium ruler is to reduce the frequency and amplitude of handlebar swing during high-speed riding, full-throttle starts, and when going over ditches and bumps, thereby improving the stability of the vehicle when cornering.

[0003] Titanium dampers are a double-edged sword, much like shock absorbers. Prioritizing handling means sacrificing comfort, and vice versa. Better damping from titanium dampers reduces vehicle agility, while increased agility increases the risk of nose-swaying at high speeds. Furthermore, existing dampers lack adjustable damping effects and cannot adapt to road conditions, thus limiting their effectiveness. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable damper.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An adjustable damper includes cylinder body one, cylinder body two, and cylinder body three. Cylinder body one and cylinder body two are threaded together, and cylinder body two and cylinder body three are an integral structure. Cylinder body one has a sleeve inside, which divides cylinder body one into an inner cavity and an outer cavity. A sealing structure and an end cap are respectively installed at the ends of cylinder body one and cylinder body two. A rod sleeve is installed between the sealing structure and the end cap connected to cylinder body one. A valve stem is inserted into the rod sleeve, and the valve stem passes through the sleeve and the end cap. A piston one is installed on the valve stem. Cylinder body two has oil hole one and oil hole two, and the sleeve has oil hole three. A flow regulating mechanism is installed in oil hole one. The inner cavity and the outer cavity are connected through oil hole one, oil hole two, and oil hole three. An auxiliary pressure relief structure is provided on the side wall of cylinder body two.

[0007] Preferably, the flow regulating mechanism includes a threaded seat that is threaded to the cylinder body, a connecting rod that is rotatably connected to the threaded seat, a cap that is connected to the upper end of the connecting rod, a damping structure that is provided between the cap and the threaded seat, a tapered plug that is slidably connected to the lower end of the connecting rod, the tapered plug being threaded to the threaded seat, and the tapered plug being located in an oil hole.

[0008] Preferably, the auxiliary pressure relief structure includes a cylinder body three, which is connected to a cylinder body two through a stepped hole. A movable ball is provided in the stepped hole. A sealing cover is installed at the end of the cylinder body three. An air hole is provided on the sealing cover. A screw is threaded to the air hole. A piston two is connected to the sealing cover through an elastic element.

[0009] Preferably, both sides of the piston are provided with retaining rings, which engage with the retaining rings on the valve stem, and a buffer ring is installed on the valve stem.

[0010] Preferably, both the valve stem and the stem sleeve are threaded with ball heads at their ends.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model installs the valve stem and sleeve on the motorcycle body and handlebars through a ball joint. When the handlebars wobble due to loss of control, the valve stem is pulled and moves to the left, causing the piston to move. The oil on the left side of the inner cavity of the piston is compressed and enters the outer cavity through oil holes one and two, and flows back to the right side of the inner cavity of the piston through oil hole three, thereby reducing the wobble of the handlebars. At the same time, the effective area of ​​the oil hole one can be changed by rotating the cap, thereby adjusting the flow rate per unit time and changing the speed of the valve stem movement.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-3An adjustable damper includes a cylinder body 1, a cylinder body 2, and a cylinder body 3 5. Cylinder body 1 and cylinder body 2 are threaded together and are an integral structure. A sleeve 13 is provided inside cylinder body 1, which divides cylinder body 1 into an inner cavity and an outer cavity. A sealing structure 8 and an end cap 3 are respectively installed at the ends of cylinder body 1 and cylinder body 2. A rod sleeve 9 is installed between the sealing structure 8 and the end cap 3 connected to cylinder body 1. A valve stem 7 is inserted into the rod sleeve 9, which passes through the sleeve 13 and the end cap 3. A piston 10 is installed on the valve stem 7. Oil holes 1 and 2 are provided on cylinder body 2, and oil hole 3 is provided on sleeve 13. A flow regulating mechanism is provided in oil hole 1. The inner cavity and the outer cavity are connected through oil holes 1, 2, and 3. An auxiliary pressure relief structure is provided on the side wall of cylinder body 2.

[0019] The valve stem 7 and the sleeve 9 are mounted on the motorcycle body and the handlebars via the ball joint 4. When the handlebars wobble due to loss of control, the valve stem 7 is pulled and moves to the left, causing the piston 10 to move. The oil on the left side of the inner cavity of the piston 10 is compressed and enters the outer cavity through oil holes 1 and 2, and then flows back to the right side of the inner cavity of the piston 10 through oil hole 3, thereby reducing the wobble of the handlebars. At the same time, the cone plug 15 can be driven up and down by rotating the cap 6, changing the effective area of ​​oil hole 1, adjusting the flow rate per unit time, and changing the speed of the valve stem 7.

[0020] In this embodiment, the flow regulating mechanism includes a threaded seat 14 that is threadedly connected to the cylinder body 2. A connecting rod 17 is rotatably connected to the threaded seat 14. A cap 6 is connected to the upper end of the connecting rod 17. A damping structure 16 is provided between the cap 6 and the threaded seat 14. A conical plug 15 is slidably connected to the lower end of the connecting rod 17. The conical plug 15 is threadedly connected to the threaded seat 14 and is located in an oil hole.

[0021] In this embodiment, the auxiliary pressure relief structure includes a third cylinder 5, which is connected to a second cylinder 2 through a stepped hole 22. A movable ball 23 is provided in the stepped hole 22. A sealing cover 18 is installed at the end of the third cylinder 5. The sealing cover 18 is provided with an air hole, and a screw 19 is threadedly connected to the air hole. The sealing cover 18 is connected to a second piston 21 through an elastic element 20. When the external cavity pressure is too high, oil enters the third cylinder 5 through the gap between the movable ball 23 and the stepped hole 22, and pushes the second piston 21 to move, preventing the cylinder from bursting or being damaged due to excessive pressure.

[0022] In this embodiment, both sides of the piston 10 are provided with retaining rings 11, which are engaged with the retaining slots on the valve stem 7, and a buffer ring 12 is installed on the valve stem 7.

[0023] In this embodiment, both the valve stem 7 and the stem sleeve 9 are threaded with ball heads 4.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
