Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically to automotive engine camshaft bushings. Background Technology

[0002] Automobiles are extremely common in modern life. The production process of automobiles involves many parts, among which the engine is particularly important. Camshaft bearing sleeves are one such component in the engine. Bushings are accessories used on mechanical parts to achieve functions such as sealing and wear protection. They are rings that act as gaskets. In moving parts, long-term friction causes wear. When the clearance between the shaft and the hole wears to a certain extent, the parts must be replaced. Therefore, designers choose materials with lower hardness and better wear resistance for bushings or camshafts to reduce wear on the shaft and housing. When the bushing or camshaft wears to a certain extent, it is replaced, thus saving the cost of replacing the shaft or housing.

[0003] However, modern car engine camshaft bushings have poor lubrication effects from lubricating oil. Some debris in the lubricating oil can damage the camshaft and affect its normal use. Utility Model Content

[0004] To solve the aforementioned technical problems, a camshaft bushing for an automotive engine is provided. This technical solution addresses the issues raised in the background section, such as poor lubrication of the lubricating oil, and the potential for camshaft damage due to debris in the lubricating oil, thus affecting the normal operation of the camshaft.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A camshaft bushing for an automotive engine includes a bushing body. A transverse groove is provided at the middle position of the inner wall of the bushing body. An arc-shaped groove is provided on the inner wall of the bushing body. A pad is provided inside the arc-shaped groove. A groove is provided on one side of the pad. The arc-shaped groove passes through the transverse groove to form a connection. A cavity is formed between the arc-shaped groove and the pad.

[0007] Preferably, the front surface of the bushing body is provided with a discharge mechanism for discharging lubricating oil, and the rear surface of the bushing body is provided with a feeding mechanism for feeding lubricating oil.

[0008] Preferably, the discharge mechanism includes a discharge pipe, the feeding mechanism includes a feeding pipe, the inside of the feeding pipe is rotatably connected with fan blades, the feeding pipe is provided with filter holes on both sides, and the discharge pipe is provided with feed inlets on both sides.

[0009] Preferably, both the feed pipe and the discharge pipe are provided with through holes at their ends, and both the feed pipe and the discharge pipe are provided with external threads on their outer sides. The feed pipe and the discharge pipe are rotatably and detachably connected to the bushing body through the external threads.

[0010] Preferably, the filter holes and the feed inlet are connected to the transverse groove.

[0011] Preferably, the pad is made of sponge, and the pad and the arc groove are in close contact.

[0012] Preferably, the ends of the feed pipe and the discharge pipe are arc-shaped, and the ends of the feed pipe and the discharge pipe are on the same plane as the inner wall of the bushing body.

[0013] Preferably, the bushing body is provided with sealed bearings at both the top and bottom ends.

[0014] Compared with the prior art, the present invention provides a camshaft bushing for an automobile engine, which has the following advantages:

[0015] An arc-shaped groove is designed to surround the inner wall of the bushing body and penetrate the transverse groove. At this time, the feeding mechanism injects lubricating oil into the transverse groove, and the lubricating oil in the transverse groove enters the arc-shaped groove. Because the arc-shaped groove surrounds the inner wall of the bushing body, it can provide good lubrication for the drive shaft inside the bushing body. At the same time, a pad that cooperates with the arc-shaped groove is placed inside the arc-shaped groove. The pad can absorb a certain amount of lubricating oil, which can maintain real-time lubrication of the drive shaft and thus improve the lubrication effect. Meanwhile, a groove is opened on one side of the pad. When the drive shaft rotates, some debris enters the groove, preventing the pad and the drive shaft from being gradually damaged by debris.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Example 1

[0025] Please refer to Figure 1-5 As shown, the camshaft bushing of an automobile engine includes a bushing body 1. A transverse groove 5 is provided at the middle position of the inner wall of the bushing body 1. An arc-shaped groove 4 is provided on the inner wall of the bushing body 1. A pad 11 is provided inside the arc-shaped groove 4. A groove 12 is provided on one side of the pad 11. The arc-shaped groove 5 passes through the transverse groove 5 to form a connection. A cavity is formed between the arc-shaped groove 4 and the pad 11.

[0026] In this embodiment, an arc-shaped groove 4 is set around the inner wall of the bushing body 1, and the arc-shaped groove 4 passes through the transverse groove 5. At this time, the feeding mechanism injects lubricating oil into the transverse groove 5, and the lubricating oil in the transverse groove 5 enters the arc-shaped groove 4. Because the arc-shaped groove 4 surrounds the inner wall of the bushing body 1, it can provide good lubrication for the drive shaft inside the bushing body 1. At the same time, a pad 11 that cooperates with the arc-shaped groove 4 is placed inside the arc-shaped groove 4. The pad 11 can absorb a certain amount of lubricating oil, which can maintain real-time lubrication of the drive shaft and thus improve the lubrication effect.

[0027] Example 2

[0028] Please refer to Figures 2-4 As shown, the front surface of the bushing body 1 is provided with a discharge mechanism for discharging lubricating oil, and the rear surface of the bushing body 1 is provided with a feeding mechanism for feeding lubricating oil. The discharge mechanism includes a discharge pipe 2, and the feeding mechanism includes a feeding pipe 3. The inside of the feeding pipe 3 is rotatably connected with a fan blade 6. The two sides of the feeding pipe 3 are provided with filter holes 8, and the two sides of the discharge pipe 2 are provided with inlets 7. The ends of the feeding pipe 3 and the discharge pipe 2 are both provided with through holes 9.

[0029] In this embodiment, the lubricating oil is circulated by the feeding mechanism and the discharging mechanism. A fan blade is installed inside the feeding pipe 3. When the lubricating oil enters the feeding pipe 33, the fan blade rotates to prevent impurities from clogging the through hole 9 and the filter hole 8.

[0030] Example 3

[0031] Please refer to Figure 2 and Figure 3As shown, both the feed pipe 3 and the discharge pipe 2 are provided with external threads 10 on their outer sides. The feed pipe 3 and the discharge pipe 2 are rotatably and detachably connected to the bushing body 1 through the external threads 10. The filter hole 8 and the feed port 7 are connected to the transverse groove 5.

[0032] In this embodiment, the external thread 10 facilitates the disassembly of the feed pipe 3 and the discharge pipe 2 from the bushing body 1, thereby cleaning the filtered impurities in a timely manner and preventing them from clogging. At the same time, the filter hole 8 and the feed port 7 are connected to the transverse groove 5, which facilitates the timely entry of lubricating oil into the interior of the transverse groove 5.

[0033] Example 4

[0034] Please refer to Figure 1 and Figure 5 As shown, the pad 11 is made of sponge, and the pad 11 and the arc groove 4 are in close contact with each other. The ends of the feed pipe 3 and the discharge pipe 2 are arc-shaped. The ends of the feed pipe 3 and the discharge pipe 2 are on the same plane as the inner wall of the bushing body 1. Sealed bearings are provided at the top and bottom of the bushing body 1.

[0035] In this embodiment, the sealing bearing facilitates sealing when the drive shaft rotates with the bushing body 1. The ends of the feed pipe 3 and the discharge pipe 2 are on the same plane as the inner wall of the bushing body 1, so that the ends of the feed pipe 3 and the discharge pipe 2 are in contact with the drive shaft. The material of the pad 11 is set as a sponge, which has the purpose of absorbing lubricating oil and can also deform to a certain extent, so that the drive shaft slides more smoothly inside it.

[0036] The working principle and usage process of this device are as follows: The feeding mechanism is connected to the lubricating oil inlet pipe, and the discharging mechanism is connected to the lubricating oil outlet pipe. The lubricating oil is filtered through the feeding pipe 3, which causes some impurities to be retained in the feeding pipe 3. The lubricating oil enters the interior of the transverse groove 5 and the arc groove 4 through the feeding pipe 3. The pad absorbs a certain amount of lubricating oil, which makes the lubrication effect of the drive shaft inside the bushing body 1 better. When the lubricating oil is cut off, it can temporarily provide lubrication. The lubricating oil enters the discharging pipe 2 from the feeding port 7 through the transverse groove 5 and the arc groove 4, and the discharge is completed.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
