Description

Technical Field

[0001] This invention relates to the field of hydropneumatic suspension technology, specifically a high-load-bearing hydropneumatic suspension mechanism. Background Technology

[0002] Hydro-pneumatic suspension, also known as hydro-pneumatic spring suspension, is a suspension system that uses hydro-pneumatic springs. The fluid in hydro-pneumatic suspension is oil as the force transmission medium, and the gas is an inert gas, often nitrogen, as the elastic medium of the suspension system. The main components are accumulators and suspension cylinders. It combines the elastic components and shock absorbers of traditional suspensions and is specifically designed for vehicles operating in harsh environments, such as heavy-duty engineering vehicles like super-large sand and gravel trucks used in mining sites. It is designed to mitigate impacts and reduce bumps, thereby reducing the loss of loaded materials, improving driving comfort, and increasing vehicle speed, which substantially helps with engineering efficiency.

[0003] In practical use, during driving, when the suspension system is subjected to force, the liquid and gas within the hydropneumatic spring simultaneously compress and expand, generating elastic deformation resistance. At this point, the elastic and damping effects work together to provide better shock absorption for the vehicle. However, the compression and expansion of the liquid and gas generate heat energy during this process. This heat energy leads to increased oil temperature, decreased viscosity, reduced suspension damping, deviation from design values, and even cavitation, accelerating component wear and reducing lifespan. Therefore, this paper proposes a high-load-bearing hydropneumatic suspension mechanism with heat dissipation capabilities. Summary of the Invention

The rotating cylinder 403 is rotatably connected between the two fixed ring seats 402 and passes through the two fixed ring seats 402. The impeller blades 404 are formed on the outer wall of the rotating cylinder 403. The connecting pipe heads a408 and b409 are symmetrically distributed and fixed to the outer side of the drain cylinder 401, and are connected to the space of the two fixed ring seats 402. The coolant entering the drain cylinder 401 from head b409 is used to impact and drive the impeller blades 404; the spiral blades 405 are formed on the inner side of the rotating cylinder 403; the connecting pipe heads c406 and d407 are symmetrically distributed at both ends of the drain cylinder 401 and penetrate into the interior of the drain cylinder 401; the two ends of the rotating cylinder 403 are respectively sleeved with the outer walls of the connecting pipe heads c406 and d407 and are rotatably connected; the flow hole 411 is opened in a fixed ring seat 402 away from the connecting pipe heads a408 and b409 and penetrates both ends of the fixed ring seat 402; the connecting pipe head e410 penetrates from one end outside the drain cylinder 401 into the interior of the drain cylinder 401 and is close to the end of the flow hole 411; The oil delivery assembly 5 includes a first pipe 501, a second pipe 502, a third pipe 503, a fourth pipe 504, a fifth pipe 505, and a sixth pipe 506. A drain check valve a207 is connected to a connecting pipe head a408 via the first pipe 501, and a drain check valve b209 is connected to a connecting pipe head b409 via the second pipe 502, for delivering coolant from the fixed outer cylinder 202 to the drain cylinder 401. An outlet check valve c306 is connected to a connecting pipe head c406 via the third pipe 503, for delivering coolant from the piston rod 102 to the rotating cylinder 403. An inlet check valve a206 is connected to the condenser output via the fourth pipe 504, and an inlet check valve b208 is connected to the condenser output via the fifth pipe 505, for delivering coolant from the condenser to the fixed outer cylinder 202. The liquid inlet check valve C307 is connected to the output end of the condenser through the sixth pipe 506, which is used to deliver the coolant inside the condenser to the piston rod 102. The connecting pipe head D407 and the connecting pipe head E410 are connected to the input end of the condenser through the delivery pipe, which is used to allow the coolant after heat absorption to flow back to the condenser for secondary cooling.

[0021] In this embodiment: when the piston rod 102 retracts into the outer cylinder 101, the piston rod 102 drives the linkage rod 204 to move upward synchronously through the fixing bolt 205. The linkage rod 204 pushes the extrusion plate 203 to move upward. At this time, the coolant above the extrusion plate 203 will be squeezed and discharged outward through the drain check valve a207. Then, it is transported to the input end of the condenser through the first pipe 501, the connecting pipe head a408, the inner cavity of the drain cylinder 401, the flow hole 411, the connecting pipe head e410, and the delivery pipe. At the same time, a negative pressure is generated in the space below the extrusion plate 203. This negative pressure causes the liquid inlet check valve b208 to open, and the coolant inside the condenser enters the space below the extrusion plate 203 through the fifth pipe 505 and the liquid inlet check valve b208. When the piston rod 102 moves to the outside of the outer cylinder 101, it will drive the extrusion plate 203 to move downward in sync through the linkage rod 204. At this time, the coolant in the space below the extrusion plate is squeezed and will be transported to the input end of the condenser through the drain check valve b209, the second pipe 502, the connecting pipe head b409, the inner cavity of the drain cylinder 401, the flow hole 411, the connecting pipe head e410, and the delivery pipe. Furthermore, a negative pressure is generated in the space above the extrusion plate 203, and the liquid inlet check valve a206 is opened, allowing the coolant inside the condenser to enter the space above the extrusion plate 203 through the fourth pipe 504 and the liquid inlet check valve a206. Thus, during the reciprocating movement of the piston rod 102, the coolant inside its fixed outer cylinder 202 achieves automatic circulation. The coolant entering the fixed outer cylinder 202 will come into contact with the heat sink 201 and the outer wall of the outer cylinder 101 for heat exchange, and the coolant that has absorbed heat will flow back to the condenser for secondary cooling. This reciprocating process can achieve efficient cooling of the outer cylinder 101. Additionally, when the coolant enters the inner cavity of the drain cylinder 401 through connecting pipe a408 and connecting pipe b409, the coolant impacts the impeller blades 404 on the outer wall of the rotating cylinder 403. This causes the impeller blades 104 to rotate under an eccentric force, which in turn drives the rotating cylinder 403 to rotate synchronously. The rotating cylinder 403 then drives the internal spiral blades 405 to rotate. The rotating spiral blades 405 exert a thrust on the coolant inside the rotating cylinder 403. This thrust causes the coolant inside the rotating cylinder 403 to flow from connecting pipe c406 to connecting pipe d407, thus causing the coolant inside the piston rod 102 to flow along the following trajectory: Liquid inlet tank 302 — Arc-shaped connecting tank 303 — Liquid outlet tank 301 — Through hole 304 — Docking hole 305 — Liquid outlet check valve c306 — Third pipe 503 — Connecting pipe head c406 — Rotating cylinder 403 — Connecting pipe head d407 — Delivery pipe — Condenser input end; The coolant inside the condenser will enter the inlet tank 302 through the sixth pipe 506 and the inlet check valve c307, thus realizing the circulation of coolant inside the piston rod 102. The flow of coolant can dissipate heat from the piston rod 102. By coordinating the above components, the oil-gas shock absorber 1 can achieve efficient heat dissipation, avoiding excessive oil temperature and piston rod 102 temperature that could lead to increased wear, and further improving the service life of the oil-gas shock absorber 1.

[0022] Please refer to this carefully. Figures 7 to 10 The connection positions of connecting pipe head a408 and connecting pipe head b409 to the drain cylinder 401 are offset from the center of the drain cylinder 401, so as to keep the direction of the impact force of the coolant sprayed from connecting pipe head a408 and connecting pipe head b409 on the impeller blade 404 unchanged.

[0023] In this embodiment: This structure ensures that when the coolant sprayed from the connecting pipe head a408 or the connecting pipe head b409 impacts the impeller blade 404, the rotation direction of the impeller blade 404 remains unchanged, thereby keeping the rotation direction of the spiral blade 405 inside the rotating cylinder 403 unchanged, thus ensuring stable coolant output inside the piston rod 102.

[0024] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
