Description

Technical Field

[0001] This utility model relates to a dual-pressure oil pump oil supply system with anti-collision function, belonging to the field of engine lubrication technology. Background Technology

[0002] As we all know, the oil pump plays a crucial role in the engine's lubrication system, essentially functioning as the engine's heart. In recent years, with the continuous upgrades and replacements of vehicle infotainment systems, the amount of oil required for engine lubrication has been constantly increasing. To reduce costs, it is necessary to increase the capacity of the oil pump within the original engine block structure to meet these lubrication demands. However, due to the complex internal structure and extremely limited installation space, the expansion of the oil pump's capacity is constrained.

[0003] To address the aforementioned structural limitations, a dual-pump simultaneous oil supply design can be employed. The two pumps' outlets are connected, simultaneously supplying oil to the main oil passage to meet the engine's lubrication needs. While this design is novel, it introduces a new problem: the two outlets, connected at high speed and high pressure, collide at the relatively narrow outlet, creating a significant impact force. This damages the inner wall of the oil passage and reduces the oil flow rate at the outlet, ultimately failing to achieve the designed oil supply volume.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This utility model addresses the shortcomings of the prior art by providing a dual-pressure oil pump supply system with anti-collision function. It can solve the problem of collision that occurs when two high-speed, high-pressure oils converge at a narrow oil outlet, which damages the inner wall of the oil pump's oil passage and reduces the flow rate at the oil outlet, leading to untimely oil supply.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A dual-pressure oil pump supply system with anti-collision function includes a first oil pump and a second oil pump. The first oil pump and the second oil pump are installed on the left and right sides of the crankshaft gear ring, and the crankshaft gear ring, the first oil pump and the second oil pump are all located in the engine body. The oil outlet of the first oil pump is divided into two flow channels. One flow channel is connected to the second oil pump, and the other flow channel is connected to the main oil passage inlet of the engine body. An anti-collision structure is provided between the two flow channels in the direction of oil flow.

[0008] Furthermore, the anti-collision structure is an integral part of the first pressure oil pump.

[0009] Furthermore, the second oil pump is connected to the first oil pump via a second oil pump connector.

[0010] Furthermore, one end of the second oil pump connector is fastened to the oil outlet of the second oil pump by multiple bolts, and a sealing ring a is installed between the second oil pump connector and the second oil pump.

[0011] Furthermore, the other end of the second oil pump connector is fitted into the first oil pump, and a sealing ring b is installed at the fitting.

[0012] Furthermore, the first pressure oil pump is connected to the main oil inlet of the machine body via a machine body bracket joint.

[0013] Furthermore, a sealing ring c is installed at the connection between the bottom end of the machine body bracket joint and the first oil pump.

[0014] Furthermore, the main oil inlet of the engine block is connected above the engine block bracket joint.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0016] This invention achieves a reasonable pressure distribution in the oil supply fluid domain of the dual-pressure oil pumps. Within an extremely limited installation space, the crankshaft gear ring simultaneously drives the left and right oil pumps to meet the engine's lubrication requirements. The novel structural design is easy to cast, improving the product's reliability and durability.

[0017] This invention divides the oil outlet of the first oil pump into two flow channels. One channel connects to the second oil pump, and the other connects to the main oil inlet of the engine block. An anti-collision structure is provided between the two flow channels in the direction of oil flow. This buffers the high-pressure oil flowing from the two oil pumps at the anti-collision structure, avoiding strong collision between the two high-pressure oils. The oil flows along its respective inner channel and converges into the main oil passage of the engine, avoiding pressure and flow loss and meeting the oil supply requirements.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown in the figure, this utility model provides a dual-pressure oil pump supply system with anti-collision function, including a first pressure oil pump 3 and a second pressure oil pump 4. The first pressure oil pump 3 and the second pressure oil pump 4 are installed on the left and right sides of the crankshaft gear ring 2. The crankshaft gear ring 2 and the first pressure oil pump 3 and the second pressure oil pump 4 are all located inside the engine block 1.

[0024] The crankshaft gear ring 2 rotates, which simultaneously drives the gears of the first oil pump 3 and the second oil pump 4 to rotate, so that the two oil pumps simultaneously draw oil from the oil pan and supply oil to the main oil passage of the generator.

[0025] The first oil pump outlet 8 of the first oil pump 3 is divided into two flow channels. One flow channel is connected to the second oil pump 4, and the other flow channel is connected to the main oil passage inlet 7 of the engine body. An anti-collision structure 9 is provided between the two flow channels in the direction of the oil flow. The anti-collision structure 9 is an integral structure with the first oil pump 3.

[0026] The anti-collision structure 9 serves as a buffer and guide, allowing the high-pressure oil collected from the first oil pump 3 and the second oil pump 4 to be buffered and smoothly supplied to the main oil passage of the engine body, thus achieving full lubrication of the various components inside the engine.

[0027] The second oil pump 4 is connected to the first oil pump 3 through a second oil pump connector 5. One end of the second oil pump connector 5 is fastened to the second oil pump outlet 10 of the second oil pump 4 by multiple bolts 14. A sealing ring a11 is installed between the second oil pump connector 5 and the second oil pump 4. The other end of the second oil pump connector 5 is fitted into the first oil pump 3, and a sealing ring b12 is installed at the fitting.

[0028] The second oil pump connector 5 delivers the oil drawn up by the second oil pump 4 to the first oil pump 3.

[0029] The first high-pressure oil pump 3 is connected to the main oil inlet 7 of the machine body via the machine body bracket joint 6. A sealing ring c13 is installed at the connection between the bottom of the machine body bracket joint 6 and the first high-pressure oil pump 3. The upper part of the machine body bracket joint 6 is connected to the main oil inlet 7 of the machine body. The machine body bracket joint 6 delivers the collected high-pressure oil to the main oil inlet 7 of the machine body.

[0030] The specific working principle of this utility model is as follows:

[0031] This invention achieves a rational pressure distribution in the oil supply fluid domain of the dual-pressure oil pumps. Within an extremely limited installation space, the crankshaft gear ring simultaneously drives both left and right oil pumps to meet the engine's lubrication requirements. This novel structural design is easy to cast, improving the product's reliability and durability.

[0032] This invention divides the oil outlet of the first oil pump into two flow channels. One channel connects to the second oil pump, and the other connects to the main oil inlet of the engine block. An anti-collision structure is provided between the two flow channels in the direction of oil flow. This buffers the high-pressure oil flowing from the two oil pumps at the anti-collision structure, avoiding strong collision between the two high-pressure oils. The oil flows along its respective inner channel and converges into the main oil passage of the engine, avoiding pressure and flow loss and meeting the oil supply requirements.
