[0023] According to an embodiment of the present invention, a high-load-bearing and lightweight universal joint head is provided.

[0024] Example 1;

[0025] like Figure 1-5 As shown, the high-load-bearing lightweight universal joint head according to an embodiment of the present invention includes a universal joint fork 1 and a universal joint fork 2. A cross shaft 3 is provided between the universal joint fork 1 and the universal joint fork 2. The cross shaft 3 is connected to the universal joint fork 1 and the universal joint fork 2 respectively through a connecting block 4. A lubrication assembly is provided on one side of the connecting block 4. The lubrication assembly includes an oil tank 5 provided on one side of the connecting block 4. A lubrication groove 6 is formed in the connecting block 4. One end of the cross shaft 3 extends into the lubrication groove 6 and is connected to a cam 7. The fuel tank 5 has an oil storage tank 8. A flow channel 9, which communicates with the lubrication tank 6, is provided at the bottom of the oil storage tank 8. The fuel tank 5 has a flow port 10 that communicates with the oil storage tank 8 and the flow channel 9. A piston 11 is provided in the flow channel 9. A spring 12 is provided on one side of the piston 11 and connected to the fuel tank 5. A pressure rod 13 is provided on the side of the piston 11 away from the spring 12. One side of the pressure rod 13 extends into the lubrication tank 6 and is connected to the fan-shaped pressure block 14.

[0026] Example 2;

[0027] like Figure 1-5As shown, the system includes a universal joint fork 1 and a universal joint fork 2. A cross shaft 3 is provided between the universal joint fork 1 and the universal joint fork 2. The cross shaft 3 is connected to the universal joint fork 1 and the universal joint fork 2 respectively via a connecting block 4. A lubrication assembly is provided on one side of the connecting block 4. The lubrication assembly includes an oil tank 5 provided on one side of the connecting block 4. A lubrication groove 6 is formed in the connecting block 4. One end of the cross shaft 3 extends into the lubrication groove 6 and is connected to a cam 7. A storage tank 5 is provided. The oil tank 8 has a flow channel 9 at its bottom, connected to the lubrication tank 6. The oil tank 5 has flow ports 10 connected to both the oil tank 8 and the flow channel 9. A piston 11 is fitted into the flow channel 9, with a spring 12 on one side connected to the oil tank 5. A pressure rod 13 is located on the side of the piston 11 away from the spring 12, extending into the lubrication tank 6 and connecting to a sector-shaped pressure block 14. A mounting slot 15 is provided on one side of the connecting block 4, matching the universal joint fork 1 and universal joint fork 2. The connecting block 4 is connected to the universal joint fork 1 and universal joint fork 2 respectively by bolts 16. A refueling pipe 17, connected to the oil tank 8, is located at the top of the oil tank 5, with a pipe cap 18 at the top. A filter screen is fitted into the refueling pipe 17. The fan-shaped pressure block 14 has guide blocks 19 at both ends, and the lubrication groove 6 has guide rods 20 symmetrically arranged and passing through the two sets of guide blocks 19 respectively. The guide blocks 19 have sliding holes that match the guide rods 20.

[0028] In practical application, lubricating oil is poured into the oil reservoir 8 through the filling pipe 17, and then the pipe cap 18 is closed. When the universal joint fork 1 or universal joint fork 2 rotates, it will drive the connecting block 4 to rotate. The connecting block 4 drives the sector-shaped pressure block 14 to squeeze the cam 7. At this time, the sector-shaped pressure block 14 will squeeze the piston 11 through the pressure rod 13. The piston 11 is forced to move and compress the spring 12. When the piston 11 leaves the flow port 10, the lubricating oil in the oil reservoir 8 enters the flow channel 9 through the flow port 10. Then the lubricating oil flows through the flow channel 9 to the lubrication channel 6 to lubricate the cross shaft 3. When the connecting block 4 drives the sector-shaped pressure block 14 to rotate, the lubricating oil will be able to move. When the pressure block 14 moves away from the cam 7, the spring 12 resets and drives the piston 11 to move to the flow port 10 to block it and prevent the lubricating oil from drying out. During use, the universal joint can be lubricated by the lubrication assembly to prevent wear on the universal joint. At the same time, the lubrication assembly works with the piston, spring, pressure rod, sector pressure block and cam. When the universal joint fork rotates, the sector pressure block will squeeze the cam to make the oil reservoir and the lubrication groove connected. The lubricating oil enters the lubrication groove to lubricate the universal joint. When the universal joint fork does not rotate, the oil reservoir and the lubrication groove are closed to prevent the lubricating oil from flowing out.

[0029] In summary, with the help of the above-mentioned technical solution of this utility model, when the universal joint is in use, the lubrication component can lubricate the cross shaft to prevent wear. At the same time, the lubrication component, through the cooperation of piston, spring, pressure rod, sector-shaped pressure block and cam, when the universal joint fork rotates, its sector-shaped pressure block will squeeze the cam, so that the oil reservoir and the lubrication groove are in a connected state, and the lubricating oil enters the lubrication groove to lubricate the cross shaft. When the universal joint fork does not rotate, the oil reservoir and the lubrication groove are in a closed state to prevent the lubricating oil from flowing out.
