Description

Technical Field

[0001] This utility model relates to the field of oil pan technology, specifically to a lightweight oil pan for heavy-duty vehicles. Background Technology

[0002] The oil pan is the lower part of the crankcase, also known as the lower crankcase. It is located at the bottom of the engine. Lighter and heavier oil pans are often made of high-strength engineering plastics, such as nylon + glass fiber composite materials, and some also use new metal materials such as isothermal quenched ductile iron.

[0003] For example, a lightweight oil pan for heavy-duty vehicles, with announcement number "CN220539713U," uses sealing gaskets to increase the airtightness of the oil settling tank and the hexagonal screw block connection surface, thus preventing oil leakage during use and reducing wear on these surfaces, extending their service life. Reinforcing plates increase the rigidity of the connection between the bottom and sides of the oil pan body, improving the overall strength and preventing damage from impacts. However, this oil pan relies solely on natural heat dissipation from its outer surface. When the engine is under high load, the oil temperature can easily exceed 120°C, leading to a decrease in oil viscosity and accelerated wear of engine parts. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when the engine is running under high load, the oil temperature can easily exceed 120°C due to natural heat dissipation through the outer surface, which leads to a decrease in oil viscosity and accelerated wear of engine parts. Therefore, this invention proposes a lightweight oil pan for heavy-duty vehicles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a heavy-duty vehicle lightweight oil pan, including an oil pan, the outer side of which is provided with a heat dissipation structure, the heat dissipation structure including hollow columns and heat dissipation fins, the outer walls of multiple hollow columns are fixedly connected to the inner wall of the oil pan, multiple heat dissipation fins are installed on both sides of the oil pan, and multiple mounting holes are machined on the upper part of the inner wall of the oil pan.

[0006] Preferably, a second groove is machined on the left side of the inner wall of the oil pan.

[0007] Preferably, the outer wall of the oil pan is machined with a plurality of first grooves.

[0008] Preferably, the oil pan has an oil drain hole at the bottom of its inner wall.

[0009] Preferably, an oil drain plug is installed on the inner wall of the oil drain hole.

[0010] The present invention proposes a lightweight oil pan for heavy-duty vehicles, which has the following advantages: through the cooperation of the oil pan and the heat dissipation structure, multiple hollow columns can increase the contact area between the oil pan and the engine oil, and multiple heat dissipation fins can increase the contact area between the oil pan and the air. The hollow columns and heat dissipation fins can accelerate the heat transfer speed and reduce the situation where the engine oil temperature easily exceeds ℃ when the engine is running under high load, which leads to a decrease in engine oil viscosity and accelerated wear of engine parts.

[0013] The present invention will be further described below with reference to the accompanying drawings: See attached document Figure 1-5 In this embodiment, a heavy-duty vehicle lightweight oil pan includes an oil pan 1. The oil pan 1 is made of isothermal hardened ductile iron. A heat dissipation structure 2 is provided on the outer side of the oil pan 1. The heat dissipation structure 2 includes hollow columns 201 and heat dissipation fins 202. The outer walls of multiple hollow columns 201 are fixedly connected to the inner wall of the oil pan 1. Multiple heat dissipation fins 202 are installed on both sides of the oil pan 1. Multiple mounting holes 3 are machined on the upper part of the inner wall of the oil pan 1.

[0014] The inner wall of the oil pan 1 has a second groove 7 machined on the left side, and the outer wall of the oil pan 1 has multiple first grooves 6 machined on it. There is an oil drain hole 4 at the bottom of the inner wall of the oil pan 1, and an oil drain plug 5 is installed on the inner wall of the oil drain hole 4.

[0015] When using a heavy-duty vehicle's lightweight oil pan: The operator uses bolts to pass through the mounting hole 3 and install the oil pan 1 to the bottom of the engine. During engine operation, lubricating oil (i.e., engine oil) flows from the engine into the oil pan 1. The second groove 7 can make the local engine oil form a relatively stable area, reducing the large-scale shaking of the engine oil and ensuring that the oil pump can stably draw engine oil. Multiple first grooves 6 can increase the strength of the oil pan 1 and reduce the situation where the oil pan 1 is deformed due to stress. Multiple hollow columns 201 can increase the contact area between the oil pan 1 and the engine oil, and multiple cooling fins 202 can increase the contact area between the oil pan 1 and the air. The hollow columns and cooling fins 202 can accelerate the heat transfer speed and reduce the situation where the engine oil temperature easily exceeds 120°C when the engine is running under high load, which would lead to a decrease in engine oil viscosity and accelerate the wear of engine parts. When it is necessary to drain the oil, unscrew the drain plug 5 to allow the oil to drain from the drain hole 4.

[0016] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
