Description

Technical Field

[0001] The invention relates to the technical field of engine lubrication, in particular to an engine lubrication system. Background Art

[0002] During the start-up process of existing engines, the oil pump needs to start running first. The lubricating oil is sucked into the oil pump through the oil suction plate, pumped into the oil cooler for cooling and filtering, and finally enters the main oil channel of the engine, and then distributed to other moving parts that need lubrication by the main oil channel. At normal temperature, it takes about 2 seconds for the main oil channel to build up pressure. At -35℃, it takes about 8 seconds for the main oil channel to build up pressure, and the response speed is slow. After the engine is started, if it is not fully heated up and the speed is increased and the load is added, the main oil channel will not fully build up pressure, and other moving parts will lack lubricating oil, which will cause failures such as burning of the moving parts.

[0003] Therefore, a technical solution is urgently needed to overcome the above technical problems.

DETAILED DESCRIPTION

[0018] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0019] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0020] Invention concept: The main oil channel 2 of the present invention can supply oil through two pipelines at the same time. Pipeline 1 passes the oil in the oil pan 1 through the oil suction plate 31, the oil pump 32, and the oil cooler 33 in sequence, and is pumped into the main oil channel 2 after filtering, pumping, and cooling. Pipeline 2 is an oil storage mechanism directly connected to the main oil channel 2. An oil outlet control valve is provided between the oil storage device 4 and the main oil channel 2. When the engine is started, the oil outlet control valve is opened, and the oil storage device 4 filled with oil is supplied with oil. The height difference between the oil storage device 4 and the main oil channel 2 and the potential energy collection device 41 in the oil storage device 4 enable pipeline 2 to respond instantly when the oil outlet control valve is opened, and quickly pump out the oil in the oil storage device 4. At the same time, the engine is running, prompting the oil pump 32 to pump the oil in the oil pan 1. During the process of cooling and filtering the oil through the first oil outlet mechanism 3, the oil storage device 4 continues to supply oil to the main oil channel 2, the oil in the oil storage device 4 decreases, the elastic potential energy stored in the spring also decreases, and the pressure of the piston decreases. At the same time, the pressure is gradually built up in the first oil outlet mechanism 3, and the conversion from oil supply by the oil storage device 4 to oil pumping by the first oil outlet mechanism 3 is realized. When the pressure in the main oil channel 2 reaches the preset value, or there is no residual oil in the oil storage device 4, the oil storage device controller 53 controls the oil outlet control valve to close, and the main oil channel 2 is completely supplied with oil by the first oil outlet mechanism 3. During the operation of the engine, the first oil outlet mechanism 3 supplies oil to the main oil channel 2 and the oil storage device 4 at the same time. The oil storage device 4 is provided with a sensor that can detect the remaining oil. When the oil storage device 4 is full of oil, the oil inlet check valve 61 at the bottom of the oil storage device 4 is closed, and the first oil outlet mechanism 3 only supplies oil to the main oil channel 2. The oil in the oil storage mechanism is ready for oil supply when the engine is started next time.

[0021] An engine lubrication system, such as Figure 1 As shown, it includes: an oil pan 1, the oil pan 1 can accommodate engine oil; a main oil channel 2, including a first oil inlet 21 and a second oil inlet 22; a first oil outlet mechanism 3, one end of the first oil outlet mechanism 3 is located in the oil pan 1, and the other end is connected to the first oil inlet 21, the first oil outlet mechanism 3 can cool and filter the engine oil from the oil pan 1, and deliver the engine oil pump 32 to the main oil channel 2; an oil storage device 4, the oil storage device 4 can store engine oil; a second oil outlet mechanism 5, one end of the second oil outlet mechanism 5 is connected to the oil storage device 4, and the other end is connected to the second oil inlet 22, the second oil outlet mechanism 5 is used to deliver the engine oil pump 32 in the oil storage device 4 to the main oil channel 2.

[0022] Specifically, the main oil channel 2 can supply oil through two pipelines at the same time. Pipeline 1 is through the first oil outlet mechanism 3, which sequentially passes the oil in the oil pan 1 through the oil suction plate 31, the oil pump 32, and the oil cooler 33, and is pumped into the main oil channel 2 after filtering, pumping, and cooling. Since the pipeline is long and the pumping, filtering, and cooling processes take time, the response time of the pipeline is long. During the time when the oil does not enter the main oil channel 2, the kinematic pair lacks oil cooling and lubrication, and is prone to burnout and other faults. Pipeline 2 is the second oil outlet mechanism 5, which directly connects the oil storage device 4 storing the oil to the main oil channel 2, and can quickly transport the oil in the oil storage device 4 to the main oil channel 2 before the first oil outlet mechanism 3 responds. This solves the problem of too long pipeline response time and burning of the kinematic pair in the prior art.

[0023] As an optional embodiment, the second oil delivery mechanism 5 includes: a first oil pipeline 51, one end of the first oil pipeline 51 is connected to the oil storage device 4, and the other end is connected to the second oil inlet 22; an oil delivery control valve, the oil delivery control valve is located in the first oil pipeline 51; an oil storage device controller 53, the oil storage device controller 53 is used to control the oil delivery control valve.

[0024] Specifically, a sensor is also provided in the oil storage device 4 for detecting the remaining amount of oil in the oil storage device 4. A pressure sensor is provided in the main oil passage 2. When the pressure in the main oil passage 2 reaches a preset value, or when there is no remaining oil in the oil storage device 4, the oil storage device controller 53 controls the oil outlet control valve to close, and the first oil outlet mechanism 3 supplies oil to the main oil passage 2. The oil storage control device can also control the oil inlet check valve 61. When the oil storage device 4 is full of oil, the oil inlet check valve 61 is closed.

[0025] As an optional embodiment, a potential energy collection device 41 is provided in the oil storage device 4. The potential energy collection device 41 can accumulate potential energy when the oil amount in the oil storage device 4 increases, and respond quickly when the oil outlet control valve opens to quickly pump out the oil in the oil storage device 4.

[0026] Specifically, the power for driving the oil pump 32 in the oil storage device 4 can be an energy storage device such as a spring, or other driving devices such as a hydraulic cylinder.

[0027] As an optional implementation, the oil storage device 4 is columnar, and the potential energy collection device 41 is a piston with a spring.

[0028] Specifically, the principle of the oil storage device 4 is that when the engine oil enters the oil storage device 4 through the oil inlet check valve 61, the spring in the oil storage device 4 is compressed and potential energy is accumulated until the oil storage device 4 is filled with engine oil, and then the oil inlet check valve 61 is closed. When the engine oil in the oil storage device 4 needs to be used, the oil outlet control valve at the other end of the oil storage device 4 is opened, and the engine oil in the oil storage device 4 is pumped outward under the action of gravity and the pressure of the spring, responds quickly, and enters the main oil channel 2. The oil is pumped completely by mechanical methods, without the response time of electronic equipment, without the need for additional power, and with a small size. The method is convenient and efficient.

[0029] As an optional implementation, a second oil pipeline 6 is provided between the oil storage device 4 and the oil cooler 33 , and an oil inlet check valve 61 is provided in the second oil pipeline 6 .

[0030] Specifically, the oil supply process of the present invention is as follows: when the engine is started, the oil outlet control valve is opened, and the oil storage device 4 filled with oil supplies oil. At the same time, the engine is running, prompting the oil pump 32 to pump the oil in the oil pan 1. In the process of cooling and filtering the oil through the first oil outlet mechanism 3, the oil storage device 4 continues to supply oil to the main oil channel 2, and the stored oil is reduced. When the oil in the oil storage device 4 is insufficient, the pressure of the main oil channel 2 reaches the required value, and the conversion from oil supply from the oil storage device 4 to oil pumping from the first oil outlet mechanism 3 is realized. During the operation of the engine, the first oil outlet mechanism 3 supplies oil to the main oil channel 2 and the oil storage device 4 at the same time. The oil storage device 4 is provided with a sensor that can detect the remaining oil. When the oil storage device 4 is full of oil, the oil inlet check valve 61 at the bottom of the oil storage device 4 is closed, and the first oil outlet mechanism 3 only supplies oil to the main oil channel 2.

[0031] As an optional implementation, the oil inlet check valve 61 is arranged at the bottom of the oil storage device 4 , and the potential energy collection device 41 is arranged at the top of the oil storage device 4 .

[0032] Specifically, the oil inlet check valve 61 is located at the bottom of the oil storage device 4. When there is no oil in the oil storage device 4, the bottom of the piston is close to the top of the oil storage device 4, and the spring is in a natural state or a slightly compressed state. When the oil inlet check valve 61 is opened, the oil pump 32 sends the filtered and cooled oil pump 32 into the oil storage device 4 to overcome the work of the spring. When the oil gradually fills the oil storage device 4 from the bottom, the spring is also continuously compressed. Finally, the oil storage device 4 is full of oil, the spring is compressed to the maximum extent, and responds quickly when the oil outlet control valve is opened. When the oil storage control valve 52 is just opened, the elastic potential energy of the spring is quickly released, and the oil is quickly pumped out. In the process of continuous oil discharge of the oil storage mechanism, the oil in the oil storage device 4 is reduced, the elastic potential energy stored in the spring is also reduced, and the pressure of the piston is reduced. At the same time, the pressure in the first oil outlet mechanism 3 is gradually built up, and stable oil pumping begins to be achieved, and finally the conversion from oil supply of the oil storage device 4 to oil pumping of the first oil outlet mechanism 3 is achieved.

[0033] As an optional embodiment, the first oil outlet mechanism 3 includes: an oil suction pan 31, an oil pump 32, and an oil cooler 33. A third oil pipe 34 is connected between the oil suction pan 31 and the oil pump 32. A fourth oil pipe 35 is connected between the oil pump 32 and the oil cooler 33. A fifth oil pipe 36 is connected between the oil cooler 33 and the first oil inlet 21. The oil suction pan 31 is located at the bottom of the oil pan 1. The oil in the oil pan 1 can enter the oil pump 32 through the oil suction pan 31, and then enter the oil cooler 33, and finally be pumped into the main oil channel 2.

[0034] Specifically, the oil suction pan 31 is located at the bottom of the oil pan 1 , which means that the bottom of the oil suction pan 31 is close to the bottom of the oil pan 1 and extends into the engine oil in the oil pan 1 .

[0035] As an optional implementation, the oil storage device 4 is higher in vertical height than the main oil channel 2 .

[0036] Specifically, since the oil storage device 4 is higher in vertical height than the main oil gallery 2 , when the oil outlet control valve between the oil storage mechanism and the main oil gallery 2 is opened, the gravitational potential energy enables the engine oil to spontaneously flow from the oil storage mechanism to the main oil gallery 2 .

[0037] By adopting the above technical solution, an engine lubrication system is provided, which can supply oil to the main oil channel 2 through two pipelines at the same time. Compared with the traditional first oil outlet mechanism 3 that is only filtered and cooled in the oil pan 1 and then pumped to the main oil channel 2, an additional oil storage device 4 directly connected to the main oil channel 2 is provided, and the stored oil can be directly and quickly transported to the main oil channel 2 before the first oil outlet mechanism 3 responds, so as to solve the problem of too long pipeline response time and burning of the kinematic pair in the prior art. A mechanical potential energy storage device is provided in the oil storage mechanism, which can accumulate potential energy through the process of oil storage in the oil storage mechanism, and the oil storage mechanism is higher than the height of the main oil channel 2 in vertical height. When the oil outlet control valve between the oil storage mechanism and the main oil channel 2 is opened, the potential energy accumulated in the oil storage mechanism and the height difference can achieve a rapid response and pump out the oil 32. Compared with the electronic control solution, the mechanical structure has a faster response, does not require an external power supply to provide power, and is lightweight.
