[0005] The oiling assembly includes an oil rod sliding in the steering booster and an extrusion block fixed inside the steering booster. The oil rod slides in the extrusion block, penetrates the steering booster to the outside, and an oil channel is opened inside the oil rod.

[0006] Optionally, oil storage cavities are opened inside both sides of the steering booster, the extrusion block is located on the side wall of the oil storage cavity, an extrusion groove is opened inside the extrusion block, the oil rod slides in the extrusion groove, and a spring is fixed between the oil rod and the inner wall of the extrusion groove.

[0007] Optionally, the outer portion of the oil rod is provided with a raised portion facing the direction close to the steering slide rod, the bottom of the raised portion is sprayed with anti-slip rubber, and the raised portion abuts against the steering slide rod.

[0008] Optionally, the middle portion of the steering slide rod is provided with oblique teeth, and the end of the steering rod is also provided with oblique teeth, and the two cooperate with each other.

[0009] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. Due to the setting of the oiling assembly, the steering slide rod can drive the oil rod to squeeze the extrusion groove, which will squeeze the lubricating oil in the extrusion groove from the oil rod to the surface of the steering slide rod to lubricate it, thereby greatly reducing its wear and consumption.

[0015] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0016] As shown in Figure 1-3, a wear-resistant steering booster includes a steering booster 10 and a steering rod 11. A steering slide rod 12 is slidably provided inside the steering booster 10. The steering slide rod 12 extends to both sides of the steering booster 10. The end of the steering rod 11 cooperates with the steering slide rod 12. The middle part of the steering slide rod 12 is provided with oblique teeth. The end of the steering rod 11 is also provided with oblique teeth. The two cooperate with each other. An oiling assembly is provided at the ends of both sides of the steering booster 10. The oiling assembly includes an oil rod 14 sliding inside the steering booster 10, and an extrusion block 15 fixed inside the steering booster 10. The oil rod 14 slides in the extrusion block 15. The oil rod 14 penetrates the steering booster 10 to the outside, and an oil channel is opened inside the oil rod 14.

[0017] An oil storage chamber 13 is provided inside the two sides of the steering booster 10, an extrusion block 15 is located on the side wall of the oil storage chamber 13, an extrusion groove 16 is provided inside the extrusion block 15, an oil rod 14 slides in the extrusion groove 16, a spring 17 is fixed between the oil rod 14 and the inner wall of the extrusion groove 16, and the outer part of the oil rod 14 is provided with a protrusion toward the direction of the steering slide bar 12, the bottom of the protrusion is sprayed with anti-slip rubber, and the protrusion abuts against the steering slide bar 12.

[0018] When in use, when the steering wheel is turned, the steering rod 11 can be driven to rotate, and the steering rod 11 rotates and drives the steering slide bar 12 to slide through the teeth. During the sliding process of the steering slide bar 12, since the anti-skid rubber of the oil rod 14 abuts against the steering slide bar 12, the oil rod 14 will be driven to move, and then the spring 17 will be compressed. The space inside the extrusion groove 16 is closed, so the lubricating oil in the extrusion groove 16 will be squeezed from the oil rod 14 to the surface of the steering slide bar 12 to lubricate it, thereby greatly reducing its wear and consumption. When the steering slide bar 12 slides in the opposite direction, the oil rod 14 will be driven to stretch the spring until the maximum distance, the oil rod 14 will be separated from the extrusion block 15, and the lubricating oil in the oil storage chamber 13 will enter the extrusion groove 16, and then the steering slide bar 12 will slide to continue to compress the spring, and the above process will be repeated to complete the process of adding lubricating oil, so that it can be lubricated for a long time and is more wear-resistant. When the wheel is in the middle, the oil rod 14 will be in the extrusion block 15, thereby preventing the lubricating oil from leaking.

[0019] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
