Patent describes the structure of diesel oil pan.
Technical field
The utility model relates to an oil pan structure of a diesel engine.
technical background
[0002] The connection structure between the oil pan structure and the front bracket of the existing diesel engine is unreasonable, which leads to the increase of production and processing costs and unreliable work. In the prior art, an oil pan structure of a diesel engine is provided, which comprises an oil pan cavity surrounded by front, rear, left and right side walls and a bottom wall, wherein the upper surface of the oil pan cavity is a connecting surface fixedly connected with a machine body, and a front bracket mounting arm fixedly connected with a front bracket is integrally formed on the side wall of the oil pan cavity. Accord to that invention, the mounting surface of the front bracket is integrate on the oil pan and cast into a whole with the oil pan, so that two mounting brackets and a plurality of mounting bolt are saved, the processing difficulty is reduced, the assembly process is simplified, the production efficiency is improved, the production cost is reduced, and the connection reliability of the front bracket is improved.
However, as far as the function of the oil pan itself is concerned, it is used to hold oil and provide lubrication for the transmission mechanism. Because the oil often contains impurities such as iron filings (iron filings are generated when the engine is working and mixed into the oil with the flow of the engine oil), the crankshaft is easily damaged after being sucked into the oil pipe by the suction cup, and the oil pipe is easily blocked, thus affecting the normal operation of the engine and shortening its service life.
Summary of the invention
[0004] In view of the shortcomings of the prior art, the utility model provides a diesel oil pan structure with good chip removal effect.
[0005] The technical scheme for solving the above technical problems is as follows:
[0006] An oil pan structure of a diesel engine comprises an oil pan cavity surrounded by front, rear, left and right side walls and a bottom wall, wherein the upper surface of the oil pan cavity is a connecting surface fixedly connected with the engine body; a front bracket mounting arm is integrally formed on the side wall of the oil pan cavity; the front bracket mounting arm is provided with a front bracket mounting hole; the bottom wall of the oil pan cavity is provided with a hollow interlayer; and at least two first magnets and at least two second magnets are arranged in the hollow interlayer.
[0007] After adopting the above scheme, the magnet in the utility model is isolated from other parts of the diesel engine because it is installed in the hollow interlayer, thus avoiding interference with other parts in the diesel engine body. The first magnet is distributed on the first circumference, the second magnet is distributed on the second circumference, and the third magnet is distributed on the third circumference. In this way, the inner bottom surface of the whole bottom shell is covered by the magnetic force generated by the magnet, and there is no dead angle in the chip removal process, so that the iron chips contained in the engine oil can be completely absorbed.
[0008] At least two first mounting brackets, at least two second mounting brackets and at least two third mounting brackets are arranged in the hollow interlayer. The first magnet is correspondingly assembled in the first mounting frame, the second magnet is correspondingly assembled in the second mounting frame, and the third magnet is correspondingly assembled in the third mounting frame. Each magnet is fixed by each mounting bracket, which avoids opening holes in the magnets and simplifies the structure of the magnets.
[0009] The bottom surface of the bottom wall is provided with a bottom plate, and a hollow interlayer is formed between the bottom wall and the bottom plate. Through this structure, the thickness of the bottom wall will not be affected, and the mold will be simplified when casting the oil pan. Moreover, the added bottom plate makes the assembly of magnets very convenient, which is also beneficial to increase the strength of the oil pan. Patent drawings
