Description

Technical Field

[0001] The invention relates to the technical field of cylinder sleeve structures, in particular to a dry type thin-wall high-strength deformation-resistant cylinder block and sleeve structure. Background Art

[0002] As the core component of the engine, the cylinder liner provides a moving track for the piston and withstands high temperature and high pressure, while also having the functions of heat dissipation and friction reduction. At present, the mainstream cylinder liners include dry, wet, coated, cast iron and aluminum alloy cylinder liners, each of which has obvious defects: dry cylinder liners are prone to deformation due to insufficient heat dissipation at high temperatures, and are prone to loosening with the cylinder body at low temperatures; wet cylinder liners are easily corroded in dusty environments and have stringent sealing requirements; coated cylinder liners are prone to peeling and cracking when the temperature changes drastically and are expensive; cast iron cylinder liners become brittle at low temperatures and soften at high temperatures; aluminum alloy cylinder liners have poor wear resistance and uneven thermal expansion and contraction.

[0003] The problem is more prominent under certain working conditions: high temperature causes material softening, low temperature causes cold start wear, sudden temperature changes cause thermal stress cracks, and dusty environments accelerate abrasive wear. These defects seriously restrict the reliability and life of the engine under extreme working conditions. When the cylinder liner is in use, the piston inside it works frequently for a long time, which will cause the temperature between the piston and the cylinder liner to increase. As the temperature increases, the lubricating oil will be consumed, further increasing the friction between the cylinder liner and the piston. Over time, the cylinder liner will be deformed and damaged, so it is necessary to manually maintain the engine and cylinder liner regularly.

[0004] In view of this, we propose a dry thin-wall high-strength deformation-resistant cylinder block and liner structure. Summary of the invention

[0018] 3. The present invention uses a guide groove design through the anti-deflection rod to accurately guide the movement of the fixed ring, so that the linkage groove is accurately aligned with the oil outlet.

The coordinated work ensures that the cylinder sleeve maintains structural stability and lasting lubrication performance under extreme working conditions such as high load and high temperature. At the same time, by optimizing the force transmission path and using special material processing, the overall structure's anti-deformation ability and service life are significantly improved.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] A dry-type thin-walled high-strength anti-deformation cylinder block and cylinder liner structure, as Figure 1 - Figure 8As shown in the figure, it includes a cylinder liner body 1, and a base 4 is fixedly connected to the bottom surface of the cylinder liner body 1; it also includes a control component 2 for automatically adding lubricating oil to the inside of the cylinder liner body 1 to prevent the cylinder liner body 1 from deforming due to excessive friction; a linkage component 3 for cooperating with the control component 2 to adjust the lubricating oil injection dose at any time; the control component 2 includes an outer protective sleeve 21, the outer protective sleeve 21 is sleeved on the outside of the cylinder liner body 1, and the outer protective sleeve 21 is fixedly connected to the cylinder liner body 1. A lubricating oil storage cavity 22 is provided inside the outer protective sleeve 21. A threaded plug 23 is threadedly connected to the top end of the lubricating oil storage cavity 22. A linkage column 24 is fixedly connected to the bottom surface of the outer protective sleeve 21. An activity cavity 25 is provided inside the linkage column 24. A limiting groove 26 is also provided inside the linkage column 24. A connecting pipe 27 penetrates and is fixedly connected to the bottom of the lubricating oil storage cavity 22. A U-shaped frame 222 is fixedly connected to the inside of the activity cavity 25. A connecting sleeve 28 is hinged inside the U-shaped frame 222. A torsion spring 29 is fixedly connected to the surface of the connecting sleeve 28. One end of the torsion spring 29 away from the connecting sleeve 28 is fixedly connected to the surface of the U-shaped frame 222. An L-shaped pipe 210 is fixedly connected to the inside of the connecting sleeve 28. One end of the L-shaped pipe 210 close to the cylinder liner body 1 is fixedly connected with an oil outlet head 211. After the lubricating oil is evenly applied inside the cylinder liner body 1, the friction inside the cylinder liner body 1 decreases, and the sliding ring 31 will not slide along with the piston due to the friction. Then the compressed spring one 217 will push the push rod 215 to reset, so that the trigger block 213 no longer toggles the L-shaped pipe 210. At the same time, the torsion spring 29 will push the connecting sleeve 28 to rotate and reset. Then the oil outlet head 211 no longer inserts into the linkage groove 36, and the sliding piece 218 will also reset along with the L-shaped pipe 210. A shaft rod 212 is fixedly connected to the inside of the activity cavity 25. The shaft rod 212 penetrates through the trigger block 213, and the trigger block 213 is rotatably connected to the shaft rod 212. The top of the trigger block 213 is an arc surface, and the arc surface of the trigger block 213 faces the L-shaped pipe 210. A telescopic rod 214 is slidably connected to the inside of the trigger block 213. The telescopic rod 214 is hinged with a push rod 215 inside, and the push rod 215 penetrates through the linkage column 24 and is slidably connected. One side of the push rod 215 close to the cylinder liner body 1 is an arc surface. A guide rod 216 is fixedly connected to the inside of the activity cavity 25. The guide rod 216 is inserted into the inside of the push rod 215 and is slidably connected. A spring one 217 is sleeved on the outside of the guide rod 216. When the sliding ring 31 moves downward, it will push the fixed ring 33 to move downward together. When the fixed ring 33 is pushed, the bottom edge of the fixed ring 33 will abut against the arc surface of the push rod 215, thereby forcing the push rod 215 to slide inward of the linkage column 24, and will rotate the trigger block 213 through the telescopic rod 214. When the push rod 215 is pushed, the spring one 217 will be compressed so that the push rod 215 can reset after no longer being abutted by the fixed ring 33. One end of the spring one 217 is fixedly connected to the inner wall of the activity cavity 25, and the other end of the spring one 217 is fixedly connected to the surface of the push rod 215.The top surface of the L-shaped pipe 210 is fixedly connected with a sliding piece 218. When the L-shaped pipe 210 rotates, it will drive the sliding piece 218 to slide in the limiting groove 26. When the sliding piece 218 slides, it will drive the sealing plug 220 to move together through the first support rod 219, so that the sealing plug 220 contacts the through hole of the lubricating oil storage cavity 22 and contracts downward. Then, the lubricating oil in the lubricating oil storage cavity 22 will pass through the sliding piece 218 and the L-shaped pipe 210, and finally enter the inner side of the fixed ring 33 through the oil outlet head 211 and the oil outlet 39. The sliding piece 218 is located inside the limiting groove 26 and is slidably connected with the limiting groove 26. The top surface of the sliding piece 218 is fixedly connected with the first support rod 219. The top surface of the first support rod 219 is slidably connected with the sealing plug 220. A second spring 221 is fixedly connected between the sealing plug 220 and the sliding piece 218.

[0023] The linkage assembly 3 includes a sliding ring 31. The top surface of the sliding ring 31 is fixedly connected with the bottom surface of the cylinder liner body 1. An anti-drop ring 32 is sleeved outside the sliding ring 31. A second support rod 34 is fixedly connected to the inner side of the cylinder liner body 1. The second support rod 34 penetrates through the anti-drop ring 32 and is slidably connected. The bottom surface of the sliding ring 31 is fixedly connected with a fixed ring 33. A linkage groove 36 is formed inside the fixed ring 33. A third spring 35 is sleeved outside the second support rod 34. When the lubricating oil inside the cylinder liner body 1 is consumed and the frictional force increases, the piston inside the cylinder liner body 1 will drive the sliding ring 31 to move downward together due to the increased frictional force when sliding. When the sliding ring 31 moves downward, it will drive the anti-drop ring 32 to slide downward inside the cylinder liner body 1 together. The second support rod 34 will prevent the anti-drop ring 32 and the sliding ring 31 from falling off the cylinder liner body 1, and the anti-drop ring 32 will compress the third spring 35. The top surface of the third spring 35 is fixedly connected with the bottom surface of the anti-drop ring 32, and the other end of the third spring 35 is fixedly connected with the inner wall of the cylinder liner body 1. A partition block 37 is slidably connected inside the linkage groove 36. After the trigger block 213 rotates, the arc surface at its top will push the L-shaped pipe 210. The L-shaped pipe 210 will drive the connecting sleeve 28 to rotate together and will compress the torsion spring 29, thereby realizing the angle adjustment of the L-shaped pipe 210. And when the fixed ring 33 moves downward, with the angle adjustment of the L-shaped pipe 210, it will drive the oil outlet head 211 to contact the arc surface of the partition block 37 and force the partition block 37 to rise, so that the oil outlet head 211 is communicated with the oil outlet 39. A fourth spring 38 is fixedly connected between the partition block 37 and the inside of the linkage groove 36. The top surface of the base 4 is fixedly connected with an anti-deviation rod 310. The anti-deviation rod 310 penetrates through the fixed ring 33 and is slidably connected. An oil outlet 39 is formed inside the fixed ring 33. The oil outlet 39 is communicated with the linkage groove 36.

[0024] When the dry type thin-wall high-strength anti-deformation cylinder block and cylinder liner structure of the present invention is in use, when the lubricating oil inside the cylinder liner body 1 is lost and the friction force increases, the piston inside the cylinder liner body 1 will drive the sliding ring 31 to move downward due to the increased friction force when sliding, and as the sliding ring 31 moves downward, it will drive the anti-slip ring 32 located inside the cylinder liner body 1 to slide downward together, and the support rod 2 34 will prevent the anti-slip ring 32 and the sliding ring 31 from falling off the cylinder liner body 1, and the anti-slip ring 32 will compress the spring 35 to facilitate subsequent sliding When the sliding ring 31 moves downward, it pushes the fixed ring 33 to move downward together. When the fixed ring 33 is pushed, the bottom edge of the fixed ring 33 will contact the arc surface of the push rod 215, thereby forcing the push rod 215 to slide to the inside of the linkage column 24, and the trigger block 213 will be turned through the telescopic rod 214. When the push rod 215 is pushed, the spring 217 will be compressed so that the push rod 215 is no longer resisted by the fixed ring 33 and resets. After the trigger block 213 rotates, the arc surface on the top of the L-shaped The L-shaped tube 210 drives the connecting sleeve 28 to rotate together and compresses the torsion spring 29, thereby realizing the angle adjustment of the L-shaped tube 210. When the fixing ring 33 moves downward, the oil outlet head 211 is driven to contact the arc surface of the isolation block 37 as the angle of the L-shaped tube 210 is adjusted, forcing the isolation block 37 to rise, so that the oil outlet head 211 is connected to the oil outlet 39. At the same time, when the L-shaped tube 210 rotates, the sliding piece 218 is driven to slide in the limiting groove 26. When the sliding piece 218 slides, it drives the sealing ring 219 to move upward. The sealing plug 220 moves together, so that the sealing plug 220 contacts the through hole of the lubricating oil storage chamber 22 and shrinks downward. At this time, the lubricating oil in the lubricating oil storage chamber 22 will pass through the slide 218 and the L-shaped tube 210, and finally enter the inner side of the fixing ring 33 through the oil outlet head 211 and the oil outlet 39. As the piston in the cylinder liner body 1 reciprocates up and down, the lubricating oil will be evenly spread, so that the friction on the inner side of the cylinder liner body 1 is reduced, thereby preventing the cylinder liner body 1 from deforming due to increased friction caused by lubricating oil loss.

[0025] After the lubricating oil is evenly applied on the inner side of the cylinder liner body 1, the friction force on the inner side of the cylinder liner body 1 is reduced, and the sliding ring 31 will not slide with the piston due to the friction force, then the compressed spring 1 217 will push the push rod 215 to reset, so that the trigger block 213 no longer moves the L-shaped tube 210, and at the same time the torsion spring 29 pushes back the connecting sleeve 28 to rotate and reset, then the oil outlet head 211 is no longer inserted into the linkage groove 36, and the sliding piece 218 will also reset with the L-shaped tube 210, when the sealing plug 220 slides to the through hole of the lubricating oil storage chamber 22, the spring 221 will lift the sealing plug 220 to seal the through hole of the lubricating oil storage chamber 22, thereby stopping the lubricating oil from entering the L-shaped tube 210, realizing adaptive lubricating oil application, and it is only necessary to unscrew the threaded plug 23 to add lubricating oil, which is more convenient.

[0026] Moreover, the anti-offset rod 310 adopts a guide groove design to precisely guide the movement of the fixing ring 33, aligning the linkage groove 36 with the oil outlet 39 precisely. The oil outlet 39 adopts a tapered design to optimize the lubricating oil flow. The lubricating oil enters the inner wall of the cylinder liner through the oil outlet 39 to form a dynamic pressure lubricating film. This structure realizes the real-time monitoring of friction force and the automatic adjustment of lubricating oil dosage through mechanical linkage. Each component adopts a modular design for easy maintenance and replacement. They work together to ensure the structural stability and lasting lubricating performance of the cylinder liner under extreme working conditions such as high load and high temperature. At the same time, by optimizing the force transmission path and using special material treatment, the anti-deformation ability and service life of the overall structure are significantly improved.
