[0001] The utility model belongs to the technical field of diesel engine push rods, and particularly relates to a relay oil push rod and a diesel engine. Background Art

[0002] In the related art, the lubrication at the valve rocker arm of a diesel engine mainly relies on a small amount of splash at the root of the push rod and the evaporation and liquefaction of oil and gas to obtain lubricating oil, and wear failures occur frequently. Under the existing conditions, if an oil passage is added for targeted lubrication, the cost is high, and the oil passage path is long, making the processing difficult. Therefore, it is urgent to design a mechanism to solve the technical problem of poor lubrication effect at the valve rocker arm.

[0003] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute the prior art. Summary of the Utility Model

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the scope of protection of the present utility model.

[0030] It has been found through research that in the related art, the lubrication at the rocker arm of the diesel engine valve mainly relies on a small amount of splash at the root of the push rod and the evaporation and liquefaction of oil and gas to obtain lubricating oil, and wear failures occur frequently. Under the existing conditions, if an oil passage is added for targeted lubrication, the cost is high, and the oil passage path is long, and the processing difficulty is large.

[0031] Based on the above research, as Figure 1 shown, the embodiments of the present disclosure provide a relay oil push rod, including: a rod body 1, and a plurality of oil storage members 2 are installed at intervals along the length direction of the rod body 1, and the inner side of the oil storage member 2 is suitable for containing lubricating oil. When the rod body 1 slides upward along the length direction, the oil storage member 2 and the lubricating oil carried by it will also move upward together. When the rod body 1 moves to the maximum stroke, the sliding direction will be changed to slide downward along the length direction. At this time, the oil storage member 2 will also slide downward accordingly, but due to inertia, the lubricating oil stored in the oil storage member 2 will still maintain the tendency to move upward, that is, continue to move upward. Therefore, when the rod body 1 slides reciprocally along the length direction, the effect of transporting the lubricating oil from low to high by the oil storage member 2 is realized.

[0032] To achieve the effect that the lubricating oil stored in the oil storage member 2 can be separated when the oil storage member 2 slides downward, as Figure 2As shown, preferably, the oil storage member 2 is an oil receiving tray, the oil receiving tray is bowl-shaped, the inner side of the oil receiving tray is recessed downward to form an oil storage space 3, and the oil receiving tray is sleeved on the outer wall of the rod body 1, so that a plurality of oil storage spaces 3 are formed on the outer wall of the rod body 1. At the same time, in order to prevent the lubricating oil from flowing out of the outer side of the edge of the oil receiving tray and causing a reduction in the amount of lubricating oil transported from low to high, the outer side of the oil receiving tray has a retaining edge 4, and the retaining edge 4 is tilted upward. In order to improve the efficiency of transporting lubricating oil from low to high, preferably, there are two oil storage members 2, and the spacing distance between the oil storage members 2 is less than the formation length of the rod body 1. Therefore, when the rod body 1 slides downward along the length direction, the lubricating oil contained in the lower oil storage member 2 will hit the cavity wall of the mounting rod body 1 during the continuous upward movement, and thus fall to the inner side of the upper oil storage member 2, and so on, so as to realize transporting the lubricating oil from the bottom of the rod body 1 to the top to lubricate the mechanism located at the top of the rod body 1.

[0033] As Figure 3 shown, at least one embodiment further provides a diesel engine that uses the relay oil push rod shown above. The diesel engine further includes a body 5. There is a push rod cavity 51 inside the body 5. The relay oil push rod is located inside the push rod cavity 51. A rocker arm 52 is rotatably provided at the top of the push rod cavity 51, and the middle part of the rocker arm 52 is rotatably connected to the body 5. A tappet 6 is also slidably provided at the bottom of the push rod cavity 51. The two ends of the relay oil push rod are respectively movably connected to the rocker arm 52 and the end of the tappet 6. Lubricating oil is stored at the bottom of the push rod cavity 51. The tappet 6 can push the rod body 1 to slide upward along the length direction, and thus push the rocker arm 52 to rotate around the connection with the body 5. The push rod cavity 51 also has a valve assembly 7. The valve assembly 7 is used to control the entry of oxygen into the cylinder. The end of the rocker arm 52 away from the rod body 1 is movably connected to the valve assembly 7.

[0034] The composition of the valve assembly 7 will be further described below. As Figure 4 shown, the valve assembly 7 includes a spring seat 71, a return spring 72 and an intake valve 73. The spring seat 71 is movably connected to the rocker arm 52. The intake valve 73 is installed at the bottom of the spring seat 71. The return spring 72 is located between the spring seat 71 and the intake valve 73, that is, one end of the return spring 72 is connected to the spring seat 71, and the other end is connected to the body 5. When the rod body 1 slides upward along the length direction, the rocker arm 52 rotates, and thus pushes the intake valve 73 to slide downward and compress the return spring 72. When the tappet 6 slides downward, the return spring 72 pushes the spring seat 71 and the intake valve 73 to lift, and the spring seat 71 pushes the rocker arm 52 to rotate in the reverse direction to drive the rod body 1 to slide downward. When the above process is cycled, the plate body 1 can transport the lubricating oil at the bottom of the push rod cavity 51 to the rocker arm 52 through the oil storage member 2 in sequence and effectively lubricate the rocker arm 52.

[0035] In several embodiments provided by the present application, it should be understood that the disclosed systems, devices, and methods can be implemented in other ways. The device embodiments described above are merely illustrative. For example, the division of the units is only a logical function division, and there can be other division methods in actual implementation. For another example, multiple units or components can be combined or integrated into another system, or some features can be ignored or not executed. Based on the ideal embodiments of the present utility model as inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present utility model. The technical scope of the present utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
