Description

Technical Field

[0001] This invention relates to the field of shock absorber technology, specifically a lightweight, high-strength motorcycle shock absorber. Background Technology

[0002] Motorcycle shock absorbers typically employ a single-cylinder or double-cylinder hydraulic damping structure, consisting of an internally fluid-filled cylinder, a piston valve system, and an externally supported coil spring. Lightweight, high-strength motorcycle shock absorbers utilize advanced materials such as forged magnesium-aluminum alloys, high-strength stainless steel, and carbon fiber composites to manufacture the cylinder body, piston rod, and connecting components, incorporating topology optimization and a hollow, lightweight structural design.

[0003] When a motorcycle speeds over a high slope and hangs in the air, the shock absorber will be subjected to a huge impact force when it falls. The shock absorber is very likely to compress to its travel limit quickly, resulting in a hard bottoming-out impact, which aggravates the fatigue wear of related components such as the frame and rocker arm. To address the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a lightweight, high-strength motorcycle shock absorber, including a connecting cylinder, a nut plate threadedly connected to the outer wall of the connecting cylinder, a spring fixedly connected to the top of the nut plate, a slide rod slidably connected to the inner wall of the end through hole of the connecting cylinder, an adjuster fixedly connected to the end of the slide rod, and a nitrogen valve penetrating the side wall of the connecting cylinder, and further comprising:

[0005] A sliding mechanism is slidably disposed on the inner wall of the connecting cylinder;

[0006] The limiting mechanism is slidably mounted at the bottom of the sliding mechanism;

[0007] Auxiliary mechanism, the inner wall of the auxiliary mechanism sliding setting limit mechanism;

[0008] Before use, staff adjust the damping coefficient of the equipment by twisting the adjuster. Several grooves are opened at the bottom of the inner wall of the connecting cylinder.

[0009] Preferably, the sliding mechanism includes:

[0010] A flow component is slidably disposed on the inner wall of the connecting cylinder;

[0011] Damping component one is slidably disposed on the outer wall of the slide rod;

[0012] When the operator twists the regulator, the regulator will adjust the distance between the damping component and the flow component.

[0013] Preferably, the limiting mechanism includes:

[0014] Damping component two is threadedly connected to the bottom end of the slide rod;

[0015] The limiting component is located at the bottom of the flow component;

[0016] When the regulator rotates, it will cause the second damping component and the first damping component to move away from or towards the flow component, thereby changing the damping coefficient of the flow component's sliding motion.

[0017] Preferably, the auxiliary mechanism includes:

[0018] A shielding component is fixedly installed on the inner wall of the limiting component;

[0019] The push component slides and is positioned on the inner wall of the limiting component;

[0020] Under normal conditions, the through holes on the shielding component and the through holes on the pushing component overlap, and the oil inside the connecting cylinder flows through the flow component, the shielding component, and the pushing component.

[0021] Preferably, the flow assembly includes a piston slidably connected to the inner wall of the connecting cylinder, an inlet is provided on the inner wall of the piston, a discharge port is provided on the inner wall of the piston, and a shielding ring is fixedly connected to the top of the inlet.

[0022] When the piston moves upward, the oil on the inner wall of the connecting cylinder will flow from top to bottom through the discharge port one, while the damping component two will block the feed port one at this time.

[0023] As the piston moves downward, the oil inside the connecting cylinder flows from bottom to top through the feed port and passes through the baffle ring.

[0024] Preferably, the damping assembly includes a nut plate 2 slidably disposed on the outer wall of the slide bar, a spring 2 fixedly connected to the bottom of the nut plate 2, and a valve plate fixedly connected to the end of the spring 2 away from the nut plate 2;

[0025] Under normal conditions, spring two will force the valve plate to press tightly against the top of the shielding ring, restricting the flow of oil from top to bottom.

[0026] Preferably, the damping assembly two includes a screw rotatably disposed on the inner wall of the piston, a spring three fixedly connected to the top of the screw, and a valve plate two fixedly connected to the other end of the spring three.

[0027] Among them, spring three will force valve plate two to be tightly attached to the outer wall of the shielding assembly. In addition, the cross-sectional width of feed port one is greater than the edge of valve plate two.

[0028] Preferably, the limiting component includes a semi-circular groove one formed at the bottom of the piston, and a semi-circular groove two formed at the bottom of the piston;

[0029] The shielding component is fixed to the inner wall of the limiting component, and there is a gap between the two. A pushing component is slidably installed inside the gap.

[0030] Preferably, the shielding component includes an arc-shaped plate 1 fixedly connected to the inner wall of the semi-arc slide groove 2, the arc-shaped plate 2 being fixedly connected to the inner wall of the semi-arc slide groove 1, and a slide groove being provided at the bottom of the arc-shaped plate 1.

[0031] Among them, the outer wall of the arc plate one is provided with a discharge port two, and the outer wall of the arc plate two is provided with a feed port two. The feed port one and the feed port two are in an overlapping state, and the discharge port one and the discharge port two are in an overlapping state.

[0032] Preferably, the pushing component includes an arc-shaped plate three that is slidably disposed on the inner wall of the semi-arc slide groove two, a folding spring fixedly connected to the side wall of the arc-shaped plate three, the other end of the folding spring being fixedly connected to the inner wall of the semi-arc slide groove two, a fixing plate fixedly connected to the bottom of the arc-shaped plate three, a universal joint fixedly connected to the side wall of the fixing plate, and a support plate fixedly connected to the end of the universal joint away from the fixing plate.

[0033] Among them, a torsion spring is fixedly connected to the outer wall of the universal joint. Under normal conditions, the torsion spring will force the support plate to tilt downward. A sharp corner is fixedly connected to the end of the support plate away from the universal joint.

[0034] The inner wall of the arc plate 3 has a feed inlet 3 and a discharge outlet 3. Under normal conditions, feed inlets 1, 2 and 3 are in an overlapping state; discharge outlets 1, 2 and 3 are in an overlapping state.

[0035] The present invention has the following beneficial effects:

[0036] (1) This invention addresses the problem that a fixed damping force can cause a hard bottom impact when the equipment is subjected to a huge impact. A limiting mechanism and an auxiliary mechanism are set inside the equipment. When the slide bar is under pressure and drives the piston to move rapidly downward along the inner wall of the connecting cylinder, the pushing component will move downward synchronously. The bottom sharp corner of the support plate will first contact the groove at the bottom of the connecting cylinder. After the sharp corner is limited, the piston continues to move downward, which will force the support plate to push the fixed plate to slide along the slide groove through the universal joint. The fixed plate will drive the arc plate three to slide along the inner wall of the semi-arc slide groove two and the semi-arc slide groove one, so that the feed port three and discharge port three of the arc plate three are misaligned with the feed port one and discharge port one. As the feed port one and feed port three are misaligned, the overlapping area of ​​the two is reduced, which will reduce the cross-section of the flow orifice. Through the application of the above components, the resistance of piston sliding is increased before hard bottom impact, and the fatigue wear of related components is reduced.

[0037] (2) The present invention utilizes the above-mentioned characteristics of the sliding of the arc plate three and the misalignment of the feed port one and the feed port three. After the support plate tip comes into contact with the groove, as the piston continues to move down, the arc plate three will start to slide along the inner wall of the semi-arc slide groove two. As the arc plate three slides, the overlapping area of ​​the feed port one and the feed port three gradually decreases, and the flow aperture also continuously shrinks. This makes the flow aperture decrease as the pressure decreases before the hard bottoming. When the equipment is subjected to excessive impact force, the piston gradually increases the sliding resistance of the piston, providing a buffer area for the hard impact of the vehicle.

[0038] (3) The present invention utilizes the feature of the support plate to push the fixed plate to move. A torsion spring is provided on the outer wall of the universal joint. The support plate is hollow. When the piston moves up and down quickly, the oil will apply a flow resistance to the support plate and force the support plate to rotate at a small angle. When the vehicle passes through a bumpy area, the piston will slide back and forth quickly on the inner wall of the connecting cylinder. At this time, the resistance of the oil will force the support plate to swing quickly. At this time, the swing of the support plate will not be able to drive the fixed plate to slide along the inner wall of the groove. Through the above design, the high-frequency movement of the piston is avoided, which will cause the feed port one and feed port three to be misaligned and affect the normal damping force of the piston.

[0039] (4) The present invention utilizes the above-mentioned arc plate three-sliding design, sets the torsion spring as a rigid material, and requires a great pressure to drive the support plate to rotate. After the feed port one and feed port three complete the movement, the feed port one and feed port three still have overlapping surfaces. The oil can flow along the overlapping surface. After the equipment has a hard bottoming out, because the feed port one and feed port three are still in a misaligned state, the flow orifice is small, the piston reset speed is slow, and the vehicle rebound speed is slower than normal. Through the above design, it is prevented that after the vehicle falls, the equipment rebounds too fast under the push of spring one, causing the vehicle body and the rider's torso to impact each other, and additionally increasing the load on the rider's torso.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Example 1, please refer to Figures 1-3This invention relates to a lightweight, high-strength motorcycle shock absorber, comprising a connecting cylinder 13, a nut plate 14 threadedly connected to the outer wall of the connecting cylinder 13, a spring 15 fixedly connected to the top of the nut plate 14, a sliding rod 16 slidably connected to the inner wall of the end through hole of the connecting cylinder 13, an adjuster 17 fixedly connected to the end of the sliding rod 16, and a nitrogen valve 18 penetratingly connected to the side wall of the connecting cylinder 13, and further comprising:

[0056] Sliding mechanism 1 is slidably disposed on the inner wall of connecting cylinder 13;

[0057] Limiting mechanism 2 is slidably disposed at the bottom of sliding mechanism 1;

[0058] Auxiliary mechanism 3, the auxiliary mechanism 3 slides on the inner wall of the limiting mechanism 2;

[0059] Before use, the staff first adjusts the damping coefficient of the equipment by twisting the adjuster 17. Several grooves are opened at the bottom of the inner wall of the connecting cylinder 13.

[0060] Sliding mechanism 1 includes:

[0061] Flow component 11 is slidably disposed on the inner wall of connecting cylinder 13;

[0062] Damping component 12 is slidably disposed on the outer wall of slide rod 16;

[0063] When the operator twists the regulator 17, the regulator 17 will adjust the distance between the damping component 12 and the flow component 11.

[0064] Limiting mechanism 2 includes:

[0065] Damping component 21 is threadedly connected to the bottom end of the slide rod 16;

[0066] Restriction component 22 is located at the bottom of flow component 11;

[0067] When the regulator 17 rotates, it will drive the second damping component 21 and the first damping component 12 away from or closer to the flow component 11, thereby changing the damping coefficient of the flow component 11 sliding.

[0068] Auxiliary mechanism 3 includes:

[0069] The shielding component 31 is fixedly disposed on the inner wall of the limiting component 22;

[0070] Push component 32, push component 32 is slidably disposed on the inner wall of restricting component 22;

[0071] Under normal conditions, the through holes on the shielding component 31 and the through holes on the pushing component 32 are in an overlapping state, and the oil inside the connecting cylinder 13 will flow through the flow component 11, the shielding component 31 and the pushing component 32.

[0072] Example 2, please refer to Figures 4-8 The present invention is a lightweight high-strength motorcycle shock absorber. Based on the first embodiment, the flow component 11 includes a piston 111 slidably connected to the inner wall of the connecting cylinder 13. The inner wall of the piston 111 is provided with a feed inlet 112 and a discharge outlet 113. A shielding ring 114 is fixedly connected to the top of the feed inlet 112.

[0073] When the piston 111 moves upward, the oil on the inner wall of the connecting cylinder 13 will flow from top to bottom through the discharge port 113, while the damping component 21 will block the feed port 112.

[0074] As the piston 111 moves downward, the oil inside the connecting cylinder 13 flows from bottom to top through the feed port 112 and passes through the shielding ring 114.

[0075] The damping assembly 12 includes a nut plate 121 that is slidably disposed on the outer wall of the slide bar 16. A spring 2 is fixedly connected to the bottom of the nut plate 121, and a valve plate 122 is fixedly connected to the end of the spring 2 away from the nut plate 121.

[0076] Under normal conditions, spring 2 will force valve plate 122 to press tightly against the top of shielding ring 114, restricting the flow of oil from top to bottom.

[0077] Damping assembly 21 includes a screw 211 rotatably disposed on the inner wall of piston 111, a spring 3 fixedly connected to the top of screw 211, and a valve plate 212 fixedly connected to the other end of spring 3.

[0078] After the equipment hits the bottom once, because the feed inlet 112 and feed inlet 3 are still misaligned, the flow orifice is small, the piston 111 resets slowly, and the vehicle rebounds slower than normal. Through the above design, it is prevented that after the vehicle crashes down, the equipment will rebound too quickly under the push of spring 15, causing the vehicle body and the rider's torso to impact each other, and additionally increasing the load on the rider's torso.

[0079] The limiting component 22 includes a semi-circular groove 221 formed at the bottom of the piston 111, and a semi-circular groove 222 formed at the bottom of the piston 111.

[0080] When the vehicle passes through a bumpy area, the piston 111 will slide back and forth quickly on the inner wall of the connecting cylinder 13. At this time, the resistance of the oil will force the support plate 325 to swing rapidly. At this time, the swing of the support plate 325 will not be able to drive the fixed plate 323 to slide along the inner wall of the groove 313. Through the above design, the high-frequency movement of the piston 111 is avoided, which will cause misalignment between the feed inlet 112 and the feed inlet 3, affecting the normal damping force of the piston 111.

[0081] The shielding component 31 includes an arc plate 311 fixedly connected to the inner wall of the semi-arc slide groove 222, an arc plate 312 fixedly connected to the inner wall of the semi-arc slide groove 221, and a slide groove 313 opened at the bottom of the arc plate 311.

[0082] As piston 111 continues to move downward, arc plate 321 will begin to slide along the inner wall of semi-arc groove 222. As arc plate 321 slides, the overlapping area of ​​feed inlet 112 and feed inlet 3 gradually decreases, and the flow orifice also shrinks. This causes the flow orifice to decrease as the downward pressure decreases before hard contact with the bottom. When the equipment is subjected to excessive impact force, piston 111 gradually increases its sliding resistance, providing a buffer zone for the hard impact of the vehicle.

[0083] The pushing component 32 includes an arc-shaped plate 321 slidably disposed on the inner wall of the semi-arc slide groove 222. A folding spring 322 is fixedly connected to the side wall of the arc-shaped plate 321. The other end of the folding spring 322 is fixedly connected to the inner wall of the semi-arc slide groove 222. A fixing plate 323 is fixedly connected to the bottom of the arc-shaped plate 321. A universal joint 324 is fixedly connected to the side wall of the fixing plate 323. A support plate 325 is fixedly connected to the end of the universal joint 324 away from the fixing plate 323.

[0084] To address the issue of a fixed damping force causing the equipment to hard-bottom-out impact when subjected to a large impact, a limit mechanism 2 and an auxiliary mechanism 3 are installed inside the equipment. Specifically, when the slide rod 16 bears pressure and drives the piston 111 to move rapidly downwards along the inner wall of the connecting cylinder 13, the pushing assembly 32 will move downwards simultaneously. The pointed bottom corner of the support plate 325 will first contact the groove at the bottom of the connecting cylinder 13. Figure 3 The B position moves down rapidly and is inserted. Figure 2At position G, after the sharp corner is limited, the piston 111 continues to move downward, which will force the support plate 325 to push the fixed plate 323 to slide along the slide groove 313 via the universal joint 324. The fixed plate 323 will drive the arc plate 321 to slide along the inner wall of the semi-arc slide groove 222 and the semi-arc slide groove 121, so that the feed port 3 and discharge port 3 of the arc plate 321 are misaligned with the feed port 112 and discharge port 113. As the feed port 112 and feed port 3 are misaligned, the overlapping area of ​​the two is reduced, which will reduce the cross-section of the flow orifice. Through the application of the above components, the resistance of the piston 111 sliding is increased before hard contact with the bottom, and the fatigue wear of the related components is reduced.

[0085] One specific application of this embodiment is as follows: Before use, the operator first controls the distance between the nut plate 2121, the screw 211 and the piston 111 by the torque adjuster 17, so that the nut plate 2121 and the screw 211 drive the valve plate 212 and the valve plate 122 to stick tightly to the outer wall of the piston 111 through the spring 2 and the spring 3. The sticking force is proportional to the damping force of the equipment.

[0086] To address the issue of a fixed damping force causing the equipment to hard-bottom-out impact when subjected to a large impact, a limit mechanism 2 and an auxiliary mechanism 3 are installed inside the equipment. Specifically, when the slide rod 16 bears pressure and drives the piston 111 to move rapidly downwards along the inner wall of the connecting cylinder 13, the pushing assembly 32 will move downwards simultaneously. The pointed bottom corner of the support plate 325 will first contact the groove at the bottom of the connecting cylinder 13. Figure 3 The B position moves down rapidly and is inserted. Figure 2 At position G, after the sharp corner is limited, the piston 111 continues to move downward, which will force the support plate 325 to push the fixed plate 323 to slide along the slide groove 313 via the universal joint 324. The fixed plate 323 will drive the arc plate 321 to slide along the inner wall of the semi-arc slide groove 222 and the semi-arc slide groove 121, so that the feed port 3 and discharge port 3 of the arc plate 321 are misaligned with the feed port 112 and discharge port 113. As the feed port 112 and feed port 3 are misaligned, the overlapping area of ​​the two is reduced, which will reduce the cross-section of the flow orifice. Through the application of the above components, the resistance of the piston 111 sliding is increased before hard contact with the bottom, and the fatigue wear of the related components is reduced.

[0087] Utilizing the sliding of the arc-shaped plate 321 and the misalignment of the feed inlet 112 with the feed inlet 3, after the sharp corner of the support plate 325 contacts the groove, as the piston 111 continues to move downward, the arc-shaped plate 321 will begin to slide along the inner wall of the semi-arc groove 222. As the arc-shaped plate 321 slides, the overlapping area of ​​the feed inlet 112 and the feed inlet 3 gradually decreases, and the flow orifice also continuously shrinks. This results in the flow orifice decreasing with the degree of downward pressure before hard contact with the bottom. When the equipment is subjected to excessive impact force, the piston 111 gradually increases the sliding resistance of the piston 111, providing a buffer area for the hard impact of the vehicle.

[0088] Taking advantage of the characteristic that the support plate 325 pushes the fixed plate 323 to move, a torsion spring is provided on the outer wall of the universal joint 324. The support plate 325 is hollow. When the piston 111 moves up and down quickly, the oil will apply a flow resistance to the support plate 325 and force the support plate 325 to rotate at a small angle. When the vehicle passes through a bumpy area, the piston 111 will slide back and forth quickly on the inner wall of the connecting cylinder 13. At this time, the resistance of the oil will force the support plate 325 to swing quickly. At this time, the swing of the support plate 325 will not be able to drive the fixed plate 323 to slide along the inner wall of the slide groove 313. Through the above design, the high-frequency movement of the piston 111 is avoided, which would cause misalignment between the feed inlet 112 and the feed inlet 3, affecting the normal damping force of the piston 111.

[0089] By utilizing the aforementioned design of the sliding of the arc-shaped plate 321, the torsion spring is made of a rigid material, requiring extremely high pressure to drive the support plate 325 to rotate. After the feed inlet 112 and feed inlet 3 have completed their full movement, there is still an overlapping surface between them, allowing the oil to flow along this surface. After the equipment experiences a hard bottoming out, because feed inlet 112 and feed inlet 3 are still misaligned, the flow orifice is small, the piston 111 resets slowly, and the vehicle rebounds slower than normal. This design prevents the equipment from rebounding too quickly under the push of spring 15 after the vehicle crashes down, thus avoiding a collision between the vehicle body and the rider's torso and increasing the load on the rider's torso.
