Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution of the present invention is further described in detail below with reference to the accompanying drawings and the detailed description.
As shown in the drawing, the oil strainer structure includes an oil pan, a first oil strainer, a second oil strainer, an oil pump 4, and a crankcase 5.
The oil pan has shallow shell portions 1a with a shallower depth and deep shell portions 1b with a deeper depth, and the bottom wall 11 at the shallow shell portions 1a is higher than the bottom wall 11 at the deep shell portions 1 b.
The first oil strainer includes a first suction pipe 21, and a first suction port 22 is provided on an end face of the first suction pipe 21, and the first suction port 22 extends into the shallow part 1a, preferably to the vicinity of the side wall 12 of the oil pan. The first oil suction port 22 faces the bottom wall 11 of the oil pan.
One side (left side in the drawing) of the first oil suction port 22 is relatively close to the depth section 1b, and the other side (right side in the drawing) of the first oil suction port 22 is relatively far from the depth section 1 b. The first oil suction port 22 is located on a side (left side in the drawing) relatively close to the deep shell portion 1b and closer to the bottom wall 11 of the shallow shell portion 1a than a side (right side in the drawing) relatively far from the deep shell portion 1b, and specifically, the first oil suction port 22 is located on an end surface of the first oil suction pipe 21, which is provided with the first oil suction port 22, and is arranged as an inclined surface forming an included angle with the bottom wall 11 (the scheme in the drawing), wherein the included angle is consistent with or close to a normal inclination angle of the engine relative to a horizontal plane, for example, 15 degrees; alternatively, it may be realized by providing the end surface of the first suction pipe 21 provided with the first suction ports 22 as a stepped surface having unevenness.
The inclined condition of the engine is that the side where the deep shell part 1b is located is inclined upwards usually, and in the inclined condition, the side (left side in the figure) of the first oil suction port 22 which is relatively close to the deep shell part 1b is easy to be exposed above the oil liquid level, in the scheme, the side (left side in the figure) of the first oil suction port 22 which is relatively close to the deep shell part 1b is closer to the bottom wall 11, so that even if the engine is inclined moderately, the first oil suction port 22 can be submerged below the oil liquid level in the shallow shell part 1a completely, and the problem that the engine is insufficient in power and even stops because the oil is always trapped in the shallow shell part 1a of the oil pan in the inclined condition of the engine can be solved.
The first oil strainer further comprises a pipe clamp 23, the pipe clamp 23 is clamped outside the first oil suction pipe 21, and a connecting hole for a fastening piece to pass through is formed in the pipe clamp 23 so as to be fixedly connected with the bottom surface of the crankcase 5 through the fastening piece. The number of the pipe clamps 23 can be set according to actual needs, and when a plurality of pipe clamps 23 are arranged, the pipe clamps 23 are sequentially arranged at intervals along the pipe length direction of the first suction pipe 21.
The second strainer includes a second suction pipe 31, and a second suction port 32 is provided on an end surface of the second suction pipe 31, and the second suction port 32 extends into the deep-shell portion 1b and faces the bottom wall 11. The end surface of the second suction pipe 31 where the second suction opening 32 is provided may be arranged as a plane parallel to the bottom wall 11, which facilitates the second suction opening 32 to suck oil. The first oil suction port 22 and the second oil suction port 32 are provided with filter screens.
The oil pump 4 includes a main pump portion and an auxiliary pump portion. The oil inlet of the sub pump section communicates with the first oil suction pipe 21, and the oil outlet of the sub pump section communicates with the deep shell section 1b, so that the engine oil in the shallow shell section 1a can be sent to the deep shell section 1 b. The oil inlet of the main pump part is communicated with the second oil suction pipe 31, and the oil outlet of the main pump part is communicated with the lubricating oil passage of the crankcase 5, so that the engine oil in the deep shell part 1b can be delivered to the inside of the crankcase 5.
The engine oil collecting and filtering structure and the engine provided by the utility model are described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
