[0027] In use, connecting rod 1 is connected to the mine car wheel frame. During the mine car's movement, when the wheels bounce, the vibration force is transmitted to connecting rod 1. Connecting rod 1, through rotating block 405, drives lifting block 304 to rise, exposing the oil inside the arc-shaped oil pipe 301 and oil pipe 2. The oil is then squeezed into connecting pipe 302 and then into the arc-shaped gas pipe 303 and the sealed space on the left side of separation plate 305. Due to the oil's high elastic modulus, it pushes itself against arc-shaped pressure block 306 to the inert gas inside arc-shaped gas pipe 303, compressing the inert gas. Shock absorption is applied to connecting rod 1 and the wheel. Simultaneously, because the arc-shaped oil pipe 301 and arc-shaped air pipe 303 are arc-shaped, the arc-shaped pressure block 306 inside the arc-shaped air pipe 303 slides along the arc-shaped surface of the arc-shaped air pipe 303 and the separating plate 305, thereby converting the originally vertical force. This significantly reduces the length of the arc-shaped oil pipe 301 and arc-shaped air pipe 303, concentrating them in one area. This avoids the problem of installation limitations due to the large outer wall surface area. Furthermore, when the mine car accelerates or brakes and experiences collisions and bumps causing vibrations, lateral vibration forces are generated in the left and right directions, thereby driving the connecting rod 1... The connecting rod 1 swings left and right, rotating on the outer wall of the rotating block 405 and causing the rotating block 405 to rotate. The rotating block 405 then drives the push rod 406 to push the sliding sleeves A407 on both sides. The sliding sleeves A407 push the internal sliding rod 408 to the sliding sleeve B409, pushing the lifting slider 410 to slide and rise on the inner wall of the lifting block 304, and pushing the oil pusher plate 411 to rise. This squeezes and pushes the oil at the top of the oil pusher plate 411. The oil at the top of the oil pusher plate 411 then enters the arc-shaped tube 402 through the fixed tube 401, and then enters the thin tube 403 through the arc-shaped tube 402 to the arc-shaped air tube 303 and the distribution tube. In the sealed cavity on the right side of the plate 305, the small arc-shaped pressure block 404 is pushed down to compress the air inside the arc-shaped air pipe 303, thereby buffering and damping the lateral force of the connecting rod 1. At the same time, the rotating block 405 drives the push rod 406 to rotate and push it to the sliding sleeve B409. When the sliding sleeve B409 pushes the lifting slider 410 to rise, the sliding sleeve B409 on the other side and the lifting slider 410 are rotated and pulled down. Thus, by rotating the connecting rod 1 in different directions, the lifting sliders 410 on the left and right sides can be driven to rise continuously and lift the push oil plate 411 to buffer and dampen the connecting rod 1.
