Description

Technical Field

[0001] The present invention relates to engine technology, and more particularly to an oil pan assembly with a built-in oil passage. Background Art

[0002] At present, most of the designs of cast oil pans for engines are designed separately, which only have the function of oil pans, and the castings do not integrate the oil channel function of the lubrication system. Such structure and oil pan design cost is low, but the oil suction pipe welding assembly of the oil pump must be designed independently. Sometimes the distance from the oil pool of the oil pan to the oil pump inlet flange is long, resulting in a long oil pipe length and a large span of the support point of the oil suction pipe welding assembly bracket. The oil suction pipe welding assembly vibrates greatly during operation, which can cause the fastening bolts to loosen and the oil suction pipe welding assembly bracket to break. Summary of the invention

[0003] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art. The purpose of the present invention is to provide a built-in oil channel oil pan assembly that integrates the oil channel function of a lubrication system.

[0004] To achieve the above-mentioned purpose, the present invention provides an oil pan assembly with a built-in oil channel, comprising an oil pan body, an oil inlet is provided at the bottom of the oil pan body, an oil outlet is provided at the end surface of the opening of the oil pan body, an oil channel is provided along the side wall of the oil pan body between the oil inlet and the oil outlet, an oil drain is provided at the bottom of the oil pan body, and a mounting surface is provided at the end surface of the opening of the oil pan body, and a plurality of first threaded holes are evenly provided on the mounting surface.

[0005] Furthermore, the oil passage includes a transverse oil passage connected to the oil inlet, a vertical oil passage connected to the oil outlet, and a side longitudinal oil passage connecting the transverse oil passage with the vertical oil passage.

[0006] Furthermore, the side longitudinal oil passage is open, a screw hole bracket is provided on the open part of the side longitudinal oil passage, a second threaded hole is provided on the screw hole bracket, a side cover plate matched with the side longitudinal oil passage is provided on the open part of the side longitudinal oil passage, a side cover plate sealing gasket is provided between the side cover plate and the side longitudinal oil passage, and a second screw passing through the side cover plate is provided in the second threaded hole.

[0007] As a further improvement, a sealing oil groove is provided on the oil outlet, and a sealing ring is provided on the sealing oil groove.

[0008] Furthermore, a mounting flange surface is provided on the oil inlet, a plurality of third threaded holes are evenly arranged on the mounting flange surface, a filter screen matching the mounting flange surface is provided on the mounting flange surface, a filter screen sealing gasket is provided between the filter screen and the mounting flange surface, and a third screw passing through the filter screen is provided in the third threaded hole.

[0009] Furthermore, an oil drain plug is provided on the oil drain port, and a sealing gasket is provided between the oil drain plug and the oil drain port.

[0010] Furthermore, the oil channel can be formed by a lateral core sand mold process built into the oil pan.

[0011] Beneficial Effects

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The built-in oil channel oil pan assembly of the present invention integrates the oil channel function of the lubrication system by building an oil channel into the oil pan. There is no need to independently set up an oil suction pipe welding assembly for the oil pump, which improves the failure of the oil suction pipe welding assembly when the distance from the oil pool of the oil pan to the oil inlet flange of the oil pump is long, thereby improving the reliability of the engine. At the same time, the die-casting process can be adopted, which has the advantages of high appearance, low cost and high reliability. BRIEF DESCRIPTION OF THE DRAWINGS
