[0048] It should be noted here that: by setting the driving assembly, it is convenient to drive the reciprocating movement of the breaking rod 703, thereby achieving reciprocating impact on the inner wall of the Z-shaped hole 301.

[0049] See also Figure 6 and Figure 7 The rotating assembly shown in the figure includes a rack 1102 fixedly connected to the floating plate 303 near the driving rod 1001, one side of the rack 1102 is connected to the push plate 404, and a gear 1101 is fixedly connected to the side wall of the driving rod 1001, and the gear 1101 and the rack 1102 are meshed with each other;

[0050] It should be noted here that: by setting the rotating assembly, it is convenient to utilize the movement of the floating plate 303 to drive the driving rod 1001 to rotate.

[0051] Working principle: When the oil shield body 102 is installed to the reducer housing 101, first insert the tail of the oil shield body 102 into the mounting hole 202 on the connecting ring 201 and fix it with a plurality of bolts 204. After the connecting ring 201 and the oil shield body 102 are connected, it can be installed in the reducer housing 101. After the oil shield body 102 is installed in the reducer housing 101, the oil seal cover 203 at one end of the connecting ring 201 will abut against the inner wall of the reducer housing 101, thereby changing the non-contact fit between the tail of the oil shield body 102 and the reducer housing 101 to an interference fit, thereby improving the oil shield body 102 and the reducer housing 101. The sealing effect between the oil shield body 102 and the gear housing 101 is improved, thereby ensuring the oil blocking effect of the oil shield body 102 during operation, thereby reducing the leakage of lubricating oil, achieving sufficient lubrication of the front drive assembly, reducing the wear of various components of the front drive assembly in the middle bridge main reducer assembly, and improving the service life and reliability, thereby improving the reliability of the entire drive axle and the vehicle, reducing the frequency and maintenance cost of the vehicle entering the station for maintenance, and improving the economic benefits of the end user. The oil seal cover 203 is made of rubber material, and its structural form can be changed in shape according to the actual situation of the oil shield body 102, thereby meeting the use of different models of vehicles, thereby improving the flexibility of the use of the sealing component;

[0052] After the sealing assembly is installed in the speed reducer ball housing 101, during normal use, the internal pressure of the lubricating oil increases continuously due to the high-speed rotation of the gears in the speed reducer housing 101 and the stirring of the lubricating oil. When the internal pressure of the lubricating oil increases, the floating plate 303 will be pushed to slide in the Z-shaped hole 301 under the action of the pressure. During the sliding process of the floating plate 303, the push plate 404 will be pushed synchronously to move close to the control circular plate 401. When the pressure continues to increase to a certain extent, one end of the push plate 404 will be against the control ball 403 on the control circular plate 401, thereby causing the control ball 403 to contact the control circular plate 401. Gaps are generated between the conical grooves 402 on the circular plate 401, and since the floating plate 303 is made of high molecular polymer, the surface has tiny pores, and the diameter of these pores is generally between 0.01-0.1 μm. Therefore, when the pressure of the lubricating oil increases to a certain extent, the high-pressure gas in the lubricating oil will pass through the pores on the surface of the floating plate 303 under the action of the pressure difference, while the lubricating oil molecules cannot pass through due to their large size, thereby achieving the function of air permeability and oil impermeability, thereby achieving the pressure regulation of the lubricating oil, ensuring the pressure balance of the lubricating oil inside the reducer housing 101, and preventing the leakage of the lubricating oil;

[0053] After the decompression of the lubricating oil inside the reducer housing 101 is completed, the pressure release will reduce the push on the floating plate 303, and then under the extrusion of the extrusion component, the control ball 403 will be pressed against the inner wall of the conical groove 402 on the control circular plate 401 again, thereby achieving sealing control of the Z-shaped hole 301 and reducing the risk of external dust and water vapor entering the reducer housing 101;

[0054] At the same time, when the floating plate 303 pushes the push plate 404 to move close to the control circular plate 401, the rack 1102 will be driven to move synchronously. When the rack 1102 moves, when the rack 1102 is meshed with the gear 1101, the gear 1101 will be driven to rotate under the meshing transmission action, thereby driving the driving ring 1002 on the side wall of the driving rod 1001 to rotate. When the driving ring 1002 rotates, each semicircular protrusion 1003 will rotate synchronously. When the semicircular protrusion 1003 is against the driving plate 1004, one end of the debonding rod 703 will be pushed away from the inner wall of the Z-shaped hole 301 under the mutual force and the guiding action of the guide component. When the semicircular protrusion 1003 passes over the driving plate 1004, under the elastic action of the reset component, The breaker rod 703 will be pushed to move closer to the inner wall of the Z-shaped hole 301 and collide with the inner wall of the Z-shaped hole 301. Therefore, in the process of the floating plate 303 constantly moving closer to the control circular plate 401, under the action of the rotating component, the semicircular protrusions 1003 on the driving ring 1002 will be driven to reciprocate and resist the driving plate 1004, and then under the mutual force and the resetting action of the resetting component, one end of the breaker rod 703 will reciprocate and collide with the inner wall of the Z-shaped hole 301, and then under the action of the vibration force, the gas distribution inside the lubricating oil is made more uniform, which is more conducive to the discharge of the gas. At the same time, under the action of the knocking vibration, the air bubbles inside the lubricating oil can be gathered faster and discharged through the Z-shaped hole 301, thereby improving the pressure release efficiency of the lubricating oil.
