Description

Technical Field

[0001] This utility model relates to the field of steering gear technology, specifically a steering gear pressure block with an oil reservoir. Background Technology

[0002] In rack and pinion steering mechanisms, the placement and use of pressure blocks are crucial for ensuring tight meshing between the steering gear and the rack, preventing vibration and collisions in the steering gear, and addressing vibration and movement issues of the rack during operation.

[0003] In traditional rack and pinion steering systems, the contact surface has relatively little lubricating oil. Due to friction, the lubrication changes non-linearly, making the rack prone to jerking during movement. In extreme cases, gaps may form between the gear and rack due to these jerking movements, potentially leading to collisions between the rack and gear in the rack and pinion steering system.

[0004] Therefore, it is necessary to design a steering gear pressure block with an oil reservoir to make the movement of the rack smoother and avoid jerking during the movement of the rack. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a steering gear pressure block with an oil reservoir, which makes the movement of the rack smoother and avoids jerking during the movement of the rack.

[0006] To achieve the above objectives, this utility model provides a steering gear pressure block with an oil reservoir, comprising a pressure block body, an oil inlet at the center of a boss at the upper end of the pressure block body, a central groove at the center of an arc surface at the lower end of the pressure block body, and several oil outlets arranged on the arc surface at the lower end of the pressure block body and evenly surrounding the central groove. The pressure block body has an oil reservoir inside, the upper end of which is connected to the oil inlet, and the lower part of the oil reservoir is divided into several oil distribution branches, the number of which is the same as the number of oil outlets, and the end of each oil distribution branch is connected to the corresponding oil outlet.

[0007] The central groove is provided with a groove on each side, one end of the groove is connected to the central groove, and the other end of the groove is located at the edge of the lower arc surface of the pressure block body.

[0008] The upper end of the pressure block body is fitted with the adjusting nut, and the diaphragm at the bottom of the adjusting nut covers and fits against the oil inlet in the center of the boss.

[0009] The protrusion is higher than the upper edge of the pressing block body.

[0010] Compared with the prior art, this utility model adds an oil storage cavity connecting the oil inlet and the oil outlet in the body of the pressure block, which facilitates grease storage and makes the grease evenly distributed on the contact surface between the pressure block and the rack, thus playing a better lubricating role. This improves the friction characteristics between the pressure block and the rack, making the movement of the rack smoother and avoiding jerking during the movement. Attached Figure Description

[0014] Figure 4 This is a cross-sectional view of the present invention in use. Detailed Implementation

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] See Figure 1 , Figure 2 and Figure 3 This utility model is a steering gear pressure block with an oil storage chamber, including a pressure block body. The upper end of the pressure block body 1 has a boss 11 with an oil inlet 3 in the center. The lower end of the pressure block body 1 has an arc surface with a central groove 12 in the center. Several oil outlets 4 are arranged on the arc surface at the lower end of the pressure block body 1 and are evenly surrounding the central groove 12. The pressure block body 1 has an oil storage chamber 2 inside. The upper end of the oil storage chamber 2 is connected to the oil inlet 3. The lower part of the oil storage chamber 2 is a number of oil distribution branches 21. The number of oil distribution branches 21 is the same as the number of oil outlets 4. The end of each oil distribution branch 21 is connected to the corresponding oil outlet 4.

[0017] To further improve the storage and lubrication of grease, a groove 13 is provided on each side of the central groove 12. One end of the groove 13 is connected to the central groove 12, and the other end of the groove 13 is located at the edge of the lower arc surface of the pressure block body 1. The grease flowing out from the oil outlet 4 can be temporarily stored in the groove 13, thereby providing auxiliary lubrication.

[0018] Grease is injected into the oil storage chamber 2 through the oil inlet 3. Affected by temperature changes and vibration, the grease will slowly seep out from several oil outlets 4 set on the arc surface at the lower end of the pressure block body 1, so that the grease is evenly distributed on the contact surface between the pressure block and the rack, which can better play a lubricating role, thereby improving the friction characteristics between the pressure block and the rack, making the movement of the rack smoother and avoiding jerking during the movement.

[0019] See Figure 4 When assembling steering gear parts, the upper end of the pressure block body 1 is fitted with the adjusting nut 5, and the diaphragm 51 at the bottom of the adjusting nut 5 covers and fits against the oil inlet 3 in the center of the boss 11. Since the boss 11 is higher than the upper edge of the pressure block body 1, the sealing of the oil inlet 3 can be further increased, preventing oil leakage to the greatest extent.

[0020] During subsequent maintenance of the steering gear, simply remove the adjusting nut 5 to separate the diaphragm 51 from the oil inlet 3, exposing the oil inlet 3. Grease can then be added through the oil inlet 3 of the pressure block body 1 while maintaining the original state of the pressure block. Furthermore, the oil reservoir 2, combined with the oil distribution branch 21 structure, can store a large amount of grease, effectively improving lubrication performance and extending the lubrication cycle.

[0021] This invention adds an oil storage cavity connecting the oil inlet and outlet inside the pressure block body, which facilitates grease storage and ensures that the grease is evenly distributed on the contact surface between the pressure block and the rack, thus improving the lubrication effect and improving the friction characteristics between the pressure block and the rack. The movement of the rack is smoother, avoiding jerking during the movement.
