Description

Technical Field

[0001] The invention relates to the technical field of engines, and in particular to an engine oil pan suitable for inclined installation. Background Art

[0002] The engine usually cannot work normally when the tilt angle is greater than 30 degrees. The main reason is that the lubricating oil cannot be absorbed well when the tilt angle is greater than 30 degrees, which will cause the engine to produce dry grinding. Long-term operation under dry grinding conditions will cause engine damage. Generally, the oil pan of the engine on the market is the same straight cylinder shape above and below. When it is tilted, the liquid level near the oil suction port will decrease. The greater the tilt angle, the lower the liquid level, so that the oil suction port cannot absorb oil normally, resulting in reduced lubrication supply and damage to the engine. Therefore, it is a problem that needs to be solved to design an oil pan that can ensure the normal supply of lubricating oil to the engine when the tilt angle is within 50 degrees. Summary of the invention

[0003] In view of the problems existing in the prior art, an object of the present invention is to provide an engine oil pan suitable for inclined installation.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely further describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] like Figure 1-4As shown, an engine oil pan suitable for inclined installation comprises an integrally formed lower bottom 3, an inclined portion 2 and a connecting portion 1, the lower bottom 3 is provided with a bottom plate for support, the edge of the bottom plate is provided with oppositely arranged first bottom straight plates 301, and an oppositely arranged second bottom straight plate 302 is provided between the two first bottom straight plates 301, a first inclined plate 201 of the inclined portion 2 is provided on the top of the first bottom straight plate 301, and a second inclined plate 202 of the inclined portion 2 is provided on the top of the second bottom straight plate 302, the first inclined plate 201 is inclined from the bottom to the top toward the inside of the oil pan, the second inclined plate 202 is inclined from the bottom to the top toward the outside of the oil pan, a first straight plate 101 of the connecting portion 1 is provided on the top of the first inclined plate 201, and a second straight plate 102 of the connecting portion 1 is provided on the top of the second inclined plate 202, and a third straight plate 103 is provided at the connection between the second straight plate 102 on one side and the first straight plate 101, and the third straight plate 103 is an inverted triangle structure.

[0019] The first straight plate 101 and the second straight plate 102 of the connecting part 1 are provided with a flange 104, and the inner edge of the flange 104 is connected to the top of the third straight plate 103 with an obtuse angle section 105 for adapting to the engine structure. The upper circumference of the flange 104 is provided with a screw hole 106 adapted to the engine for fixed connection to the engine.

[0020] The first inclined plate 201 is inclined from the bottom to the top toward the inside of the oil pan, and the second inclined plate 202 is inclined from the bottom to the top toward the outside of the oil pan, and the sum of the lengths of the two first bottom straight plates 301 and the two second bottom straight plates 302 of the lower bottom 3 is greater than the sum of the lengths of the two first straight plates 101, the two second straight plates 102 and the two third straight plates 103 of the connecting portion 1, so that the oil pan forms a box structure with a narrow upper part and a wide lower part. When the lubricating oil is in the box, when the box tilts, the amount of oil will keep the height of the liquid level near the oil suction port at the bottom of the oil suction pipe from decreasing due to the closing of the upper part, thereby ensuring that the lubricating oil can enter the lubrication system through the oil suction pipe, and ensuring that the engine can work on a slope with an inclination angle within 50 degrees.

[0021] The second bottom straight plate 302 on one side of the lower bottom 3 is provided with an oil outlet 303 for discharging the lubricating oil in the engine oil pan. The middle part of the inner side of the oil pan is provided with an oil suction pipe 4 of the engine, and the oil suction pipe 4 extends into the bottom of the oil pan for the engine to absorb the lubricating oil. The oil storage tank formed by the oil pan is narrow at the top and wide at the bottom. Generally, the oil suction port of the oil suction pipe 4 for oil suction is located in the middle of the box body near the bottom of the oil pan. When the lubricating oil is in the box body, when the box body is tilted, the amount of oil will keep the height of the liquid level near the oil suction port of the oil suction pipe 4 from decreasing due to the closing of the upper part, thereby ensuring that the lubricating oil can enter the lubrication system through the oil suction pipe 4. It is ensured that the lubricating oil can be normally absorbed when the engine is tilted in any direction within 50 degrees. In some special cases, the equipment that needs the engine as power needs to operate normally on a slope with an inclination angle of less than 50 degrees, so the normal operation of the engine is required in this case, and the decisive factor that determines whether the engine can work normally in this case is the lubrication system of the engine. Therefore, the supply of lubricating oil to the engine at a large inclination angle can ensure the normal operation of the engine, thereby enabling the equipment equipped with the engine to operate on a slope with a large inclination angle.
