The sealing plug 503 is made of rubber, both ends of the top plate 1 are curled, and the inner cavities at both ends of the top plate 1 are movably connected with connecting sleeves 6.

[0023] The above scheme is adopted: the drainage grooves 502 are fitted together to form a pipeline to transport the lubricating oil, so that the lubricating oil penetrates into the interlayer of the top plate 1 and the thickened plate 2. By setting the connecting sleeve 6, the device can be installed, and the wear of the inner cavity at both ends of the top plate 1 can be reduced, thereby increasing its service life.

[0024] refer to Figures 1 to 5, both sides of the top plate 1 and the thickened plate 2 are provided with binding hoops 7, the inner cavity of the binding hoop 7 is fixedly sleeved on the surfaces at both ends of the top plate 1 and the thickened plate 2, the four corners of the connecting plate 401 are movably connected with connecting shafts 8, the bottom of the connecting shaft 8 is movably connected with a mounting plate 9, the bottom ends of the top plate 1 and the thickened plate 2 are fixedly connected with a limiting block 11, and the tops of the thickened plate 2 and the bottom plate 3 are provided with limiting grooves 10, and the surface of the limiting block 11 is movably connected to the inner cavity of the limiting groove 10.

[0026] Working principle:

[0027] When in use, the sealing plug 503 is pulled out, the lubricating oil is injected from the inner cavity of the sealing plug 503, and the lubricating oil is transported to the contact surface between the top plate 1, the thickened plate 2 and the bottom plate 3 through the pipeline formed by the drainage groove 502, and the bottom end of the bottom plate 3 is placed on the upper side of the outer end of the axle frame, and the connecting shaft 8 is used to pass through the four corners of the connecting plate 401, and then the four corners of the mounting plate 9 are passed from the bottom of the bottom plate 3 to the outside of the bottom of the connecting shaft 8, and the nut is screwed to the lower end of the connecting shaft 8 and tightened, so that the top of the mounting plate 9 and the bottom of the bottom plate 3 clamp and fix the axle frame, and the mounting bolts are used to penetrate the connecting sleeve 6 and the bottom of the vehicle body, and the nuts are tightened to complete the installation of the device, and vibration is generated during the driving of the vehicle, so that the top plate 1, the thickened plate 2 and the two sides of the bottom plate 3 move downward, and through the rebound characteristics of the top plate 1, the thickened plate 2 and the bottom plate 3, The two sides are reset to the upper side, thereby supporting the vehicle body and achieving the effect of buffering and shock absorption. In the process of the top plate 1, the thickened plate 2 and the bottom plate 3 shaking up and down, the contact surfaces between the top plate 1, the thickened plate 2 and the bottom plate 3 are lubricated by lubricating oil, thereby reducing their surface friction. When the two sides of the device move down to a certain extent, the bottom of the vehicle body contacts the bottom end of the buffer pad 403, and the buffer pad 403 is exerted with the downward movement of the frame. The downward movement of the buffer pad 403 drives the coil spring 404 to contract, and the rebound characteristics of the coil spring 404 push the buffer pad 403 and the vehicle body to move upward. When the coil spring 404 contracts to the lowest point, the top plane of the buffer pad 403 is higher than the top plane of the top plate 1, so that the two ends of the top plate 1 will not sink to a flat state, so that the top plate 1, the thickened plate 2 and the bottom plate 3 will not sink excessively during use.

[0028] In summary: this new type of automobile leaf spring assembly, through the coordinated work of the various components of the device, solves the problem of existing equipment in actual use that when the vehicle body is overloaded, the steel plate will be pressed down to a straight state during travel, which is not conducive to the rebound of the steel plate, and it is easy to change the properties of the steel plate, reducing the rebound characteristics of the steel plate. In the process of up and down shaking, the contact surfaces between the steel plates will cause wear due to friction, which will not only cause gaps between the steel plates to cause the steel plates to shake, but also reduce the service life of the steel plates.
