Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and in particular relates to an oil pan and a vehicle equipped with the oil pan. Background Art

[0002] The engine crankcase is a hollow structure that holds the crankshaft of the car. For common engines, the crankcase is located at the bottom of the engine and is the most important part of the engine. The crankcase is installed at the bottom of the cylinder and is divided into an upper crankcase and a lower crankcase. The oil pan is the lower half of the crankcase, also known as the lower crankcase. Its function is to seal the crankcase as the outer shell of the oil storage tank to prevent impurities from entering, and to collect and store the lubricating oil flowing back from the friction surfaces of the diesel engine, dissipate some heat, and prevent the lubricating oil from oxidizing.

[0003] The upper crankcase is cast as one piece with the cylinder block, and the crankshaft runs in the upper crankcase. The crankcase is the most important component in the engine, as it bears the force from the connecting rod, converts it into torque, and outputs it through the crankshaft. A crankshaft pulley is installed on one end of the crankshaft extending out of the upper crankcase, which drives other accessories on the engine to work. It needs to have a certain strength and rigidity, so it is generally made of gray cast iron.

[0004] The lower crankcase is used to store lubricating oil and seal the upper crankcase to prevent impurities from entering. It also collects and stores lubricating oil flowing back from the friction surfaces of the diesel engine, dissipates some heat, and prevents lubricating oil from oxidizing. Therefore, it is also called the oil pan. The oil pan withstands less pressure and is generally stamped from thin steel plates. Its shape depends on the overall layout of the engine and the capacity of the oil. A gasket is installed between the flange surfaces of the upper crankcase and the lower crankcase to prevent lubricating oil leakage.

[0005] At present, with the requirements of longitudinally mounted engines based on the gear train transmission ratio and cylinder height compression, interference occurs between the crankshaft pulley and the flange surface of the oil pan. The crankshaft pulley is located at the upper right front end of the oil pan, and the front end clearance between the crankshaft pulley and the oil pan is too small, resulting in insufficient installation operating space for the oil pan, affecting the installation of the oil pan and the upper crankcase. Utility Model Content

[0006] The embodiment of the utility model provides an oil pan and a vehicle, which solves the problem of affecting the installation of the oil pan due to the small gap between the crankshaft pulley and the oil pan by optimizing the bolt layout.

[0013] In combination with the first aspect, in one feasible method, an oil filter mounting seat and an oil cooler mounting seat are arranged on the right side of the front end surface of the oil pan body, and the oil filter mounting seat is provided with a vertical through hole for allowing a vertical bolt to pass upward through the flange surface; the oil cooler mounting seat is provided with a threaded hole extending in the left and right direction.

[0014] In combination with the first aspect, in one achievable manner, the inner wall of the oil pan body is provided with internal reinforcing ribs corresponding one-to-one to the bolt holes on the flange surface, and the internal reinforcing ribs all extend toward the bottom of the oil pan body.

[0015] In combination with the first aspect, in a feasible manner, the bottom of the oil pan body is divided into a deep oil storage area, a shallow oil area and an oil guiding area from front to back, and the bottoms of the deep oil storage area, the shallow oil area and the oil guiding area are successively increased in a stepped manner; the internal reinforcing ribs in the shallow oil area and the oil guiding area are inclined toward the deep oil storage area; the internal reinforcing ribs in the deep oil storage area extend toward the middle of the deep oil storage area.

[0016] Compared with the prior art, the oil pan provided by the utility model has the following beneficial effects: by arranging a bolt support below the flange surface, the bolt installation position is moved downward to be away from the crankshaft pulley above, thereby increasing the distance between the bolt installation position and the crankshaft pulley, expanding the installation operation space, thereby improving the convenience of installation, and being able to save installation time and installation strength.

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] In the claims, specification and the above-mentioned drawings of the present utility model, the terms "up" and "down" are the same as the up and down directions of the vehicle body, the terms "front" and "rear" are the same as the front and rear directions of the vehicle body, and the terms "left" and "right" are the same as the left and right directions of the vehicle body.

[0029] Please also read Figure 1 and Figure 7 The oil pan provided by the utility model is now described. The oil pan comprises: an oil pan body 1, a bolt hole is arranged on the flange surface 17 of the oil pan body 1, a bolt support 4 is arranged on the front end surface of the oil pan body 1, the bolt support 4 is located below the flange surface 17, a mounting through hole is arranged on the bolt support 4, the mounting through hole is coaxial with the bolt hole above, and a long bolt 2 is arranged in the mounting through hole and the coaxial bolt hole.

[0030] Compared with the prior art, the oil pan provided by the utility model has the following beneficial effects: by arranging the bolt support 4 below the flange surface 17, the bolt installation position is moved downward to be away from the crankshaft pulley above, thereby increasing the distance between the bolt installation position and the crankshaft pulley, expanding the installation operation space, thereby improving the convenience of installation, and being able to save installation time and installation strength.

[0031] When the oil pan and the upper crankcase are installed, short bolts 16 are used to connect the oil pan at the positions with sufficient space on the left and right sides, and long bolts 2 are used to pass upward through the bolt support 4 and the flange surface 17 at the front end of the oil pan to connect the upper crankcase, and the installation tool is tightened below the bolt support 4. The application can solve the problem of limited installation space through the cooperation of the long bolts 2 and the short bolts 16, thereby improving the convenience of oil pan installation.

[0032] For example, the short bolt 16 is a standard bolt with a diameter of 8 mm and a length of 30 mm; the long bolt 2 is a bolt with a diameter of 8 mm and a length of 95 mm.

[0033] The installation direction of the oil pan and the upper crankcase is up and down. The installation of the up and down bolts is solved by lowering the bolt installation position. The left and right directions of the oil pan also interfere with the crankshaft pulley and affect the rotation of the crankshaft pulley. For this problem, the gap between the crankshaft pulley and the right side of the oil pan can be expanded by reducing the width of the oil pan in the left and right directions, thereby solving the interference problem between the crankshaft pulley and the right side of the oil pan.

[0034] In some embodiments, see Figure 1 and Figure 2 As shown, a vertical groove 19 for avoiding the long bolt 2 is provided on the front end surface of the oil pan body 1. The purpose of this embodiment is to provide a certain protection for the long bolt 2. Since the long bolt 2 used is relatively long, the long bolt 2 is partially exposed on the outside of the oil pan body 1 between the bolt support 4 and the flange surface 17, and the surrounding parts will scratch and collide with the long bolt 2, causing wear of the long bolt 2. By providing the vertical groove 19, the long bolt 2 is partially hidden in the vertical groove 19, which can reduce the risk of wear of the long bolt 2.

[0035] The vertical groove 19 is formed by protruding inwardly through the side wall of the oil pan body 1 , so as to prevent the long bolt 2 from protruding on the outside of the oil pan body 1 .

[0036] In some embodiments, see Figure 1 and Figure 2 As shown, the vertical groove 19 extends downward to the lower end of the oil pan body 1, forming an escape groove 5 for installing the long bolt 2 below the bolt support 4. The purpose of this embodiment is to increase the operating space of the installation tool and provide convenience for the installation tool to tighten the long bolt 2.

[0037] In some embodiments, see Figure 1 and Figure 2As shown, baffles 3 protruding from the front end surface of the oil pan body 1 are respectively provided on the left and right sides of the vertical groove 19, and the long bolts 2 are hidden in the baffles 3. The vertical groove 19 can only partially hide the long bolts 2. If the vertical groove 19 is too deep, it will also cause structural defects of the oil pan body 1. Therefore, in this embodiment, the baffles 3 are provided so that the long bolts 2 are hidden within the protection of the baffles 3. When the surrounding parts are scratched, they first contact the baffles 3, thereby avoiding scratching and damage to the long bolts 2.

[0038] In this embodiment, the baffle plate 3 and the oil pan body 1 are formed in one piece, thereby improving the overall strength of the integration.

[0039] In some embodiments, see Figure 1 and Figure 2 As shown, a reinforcing rib structure is provided on the front end surface of the oil pan body 1, and two bolt supports 4 are provided on the front end surface of the oil pan body 1; the reinforcing rib structure includes a transverse reinforcing rib 7 connected between the two bolt supports 4. In this embodiment, the supporting strength of the long bolt 2 connected to the front end of the oil pan body 1 is improved by the provided reinforcing rib structure, and in this embodiment, the two bolt supports 4 are connected together by the transverse reinforcing rib 7.

[0040] In some embodiments, see Figure 1 and Figure 2 As shown, the reinforcing rib structure further includes an X-shaped reinforcing rib 6 disposed between the flange surface 17 and the transverse reinforcing rib 7. In this embodiment, the X-shaped reinforcing rib 6 further improves the strength of the installation portion of the long bolt 2, thereby improving the firmness of the bolt connection.

[0041] The X-shaped reinforcing ribs 6 include two crossed ribs. In this embodiment, a plurality of X-shaped reinforcing ribs 6 are arranged on the front end surface of the oil pan body 1, wherein two X-shaped reinforcing ribs 6 are arranged between the transverse reinforcing ribs 7 and the flange surface 17 along the left-right direction, and the X-shaped reinforcing ribs 6 have four end points, two of which extend to the bolt hole and the bolt support 4 respectively; the other two end points of the two X-shaped reinforcing ribs 6 abut against each other, thereby forming a strong support for the flange surface 17 and the bolt support 4, avoiding the problem of deformation of the bolt support 4 due to the upward tightening force of the long bolt 2, ensuring the stability of the distance between the bolt support 4 and the flange surface 17, and thus ensuring the firmness of the long bolt 2 after installation.

[0042] Further, see Figure 1 and Figure 2 As shown, the reinforcing rib structure also includes a vertical reinforcing rib 8 arranged perpendicular to the transverse reinforcing rib 7, and the vertical reinforcing rib 8 extends downward to the lower end of the front end surface of the oil pan body 1. The transverse reinforcing rib 7 and the vertical reinforcing rib 8 form a cross-shaped structure, which forms an all-round reinforcement for the front end of the oil pan body 1. At the same time, two X-shaped reinforcing ribs 6 are arranged in the left and right directions below the transverse reinforcing rib 7.

[0043] Furthermore, a U-shaped reinforcement rib is provided below the transverse reinforcement rib 7 , the upper ends of the U-shaped reinforcement rib are respectively fixed below the bolt support, and two X-shaped reinforcement ribs are arranged in the interval surrounded by the U-shaped reinforcement rib and the transverse reinforcement rib 7 .

[0044] Optionally, the reinforcing rib structure may also be a grid structure in which a plurality of transverse reinforcing ribs 7 and a plurality of vertical reinforcing ribs 8 are cross-arranged, and the grid may be rectangular or rhombus-shaped.

[0045] In some embodiments, see Figures 1 to 7 As shown, an oil filter mounting seat 11 and an oil cooler mounting seat 12 are arranged on the right side of the front end face of the oil pan body 1. The oil filter mounting seat 11 is provided with a vertical through hole 24 for a vertical bolt to pass upward through the flange surface 17; the oil cooler mounting seat 12 is provided with a threaded hole extending in the left-right direction. Since both the oil filter 10 and the oil cooler 13 can be mounted on the oil pan body 1 and are also located at the front end of the oil pan body 1, the front end of the oil pan body 1 is reinforced by the reinforcing rib structure, which provides structural strength guarantee for the reliable installation of the oil filter 10 and the oil cooler 13.

[0046] Among them, the vertical bolts are hidden in the oil filter mounting seat 11, which solves the problem that the bolts connecting the upper crankcase cannot be set at this position, and ensures the reliability of the installation and sealing of the oil pan body 1 and the upper crankcase.

[0047] The bolt support 4 close to the oil filter mounting seat 11 is connected to the oil filter mounting seat 11 as a whole, which can also avoid deformation of the bolt support 4 and is beneficial to the reliability of the long bolt after installation.

[0048] Since the oil pan is generally formed by stamping thin steel plates or casting aluminum alloys, the oil pan not only stores the engine oil, but also seals and blocks the combustion noise in the cylinder. Since it is strongly excited by the vibration of the whole machine, its stiffness is relatively low compared to the engine cylinder, and it is easy to produce local modal deformation. The acoustic cavity formed by the sealed air between the oil pan and the cylinder block is prone to transient pressure fluctuations and radiate mid- and high-frequency noise. Therefore, the oil pan is designed to increase its strength as much as possible and optimize NVH performance under the goals of design space and weight.

[0049] Considering the working conditions of the oil pan, the oil pan is required to have high comprehensive properties such as strength, thermal conductivity, sound insulation and fatigue resistance. In order to improve the strength of the oil pan, the present application adopts the technical means of setting internal reinforcement ribs 15 inside the oil pan body 1.

[0050] Specifically, see Figure 1 and Figure 3As shown, internal reinforcing ribs 15 corresponding to the bolt holes on the flange surface 17 are arranged on the inner wall of the oil sump body 1 , and the internal reinforcing ribs 15 extend toward the bottom of the oil sump body 1 .

[0051] The inner reinforcement ribs 15 are arranged at positions corresponding to the bolt holes, which improve the overall torsional stiffness of the engine and the gearbox, increase the connection stiffness of the engine and the gearbox, increase the torsional frequency of the powertrain, and also improve the firmness of the connection between the oil pan and the upper crankcase.

[0052] The internal reinforcing ribs 15 provided in the present application not only have the function of improving the strength of the oil pan, but also have the function of heat conduction, thereby improving the heat dissipation effect of the engine oil in the oil pan.

[0053] In order to improve the structural strength of the oil pan, triangular reinforcement plates 23 are distributed around the flange surface 17 between the outer side of the oil pan body 1 and the flange surface 17 to improve the structural strength of the flange surface 17, thereby ensuring the sealing reliability after the oil pan is connected to the upper crankcase and avoiding oil leakage due to deformation of the flange surface 17.

[0054] In some embodiments, Figure 1 and Figure 3 As shown, the bottom of the oil pan body 1 is divided into a deep oil storage area 20, a shallow oil area 21 and an oil guide area 22 from front to back, and the bottoms of the deep oil storage area 20, the shallow oil area 21 and the oil guide area 22 are successively raised in a stepped manner; the inner reinforcing ribs 15 in the shallow oil area 21 and the oil guide area 22 are inclined toward the deep oil storage area 20; the inner reinforcing ribs 15 in the deep oil storage area 20 extend toward the middle of the deep oil storage area 20. The inner reinforcing ribs 15 arranged in the present application also have a guiding function, and the inclined inner reinforcing ribs 15 make the engine oil flow to the deepest deep oil storage area 20. The stepped bottom of the oil pan body 1 allows the engine oil to be collected in the deep oil storage area 20, thereby improving the effective utilization rate of the engine oil in the oil pan.

[0055] Furthermore, if Figure 1 and Figure 3 As shown, the bottom of the shallow oil area 21 is an inclined surface inclined toward the deep oil storage area 20, and the bottom inclination of the oil guide area 22 is greater than the bottom inclination of the shallow oil area 21, so that the oil can be collected in the deep oil storage area 20. The deep oil storage area 20 is provided with an oil plug 9 to discharge the oil in the oil pan body 1, clean the oil pan and change the oil.

[0056] like Figure 6 and Figure 3As shown, the rear end of the oil pan body 1 provided by the present application is provided with a flange 14 connected to the gearbox housing, and a support plate 18 is provided between the outer side of the bottom of the oil pan body 1 and the flange 14 to enhance the connection strength between the oil pan and the flange 14. The support plate 18 of the present application is provided at the outer side of the bottom of the oil guide area to compensate for the deficiency that the space below the oil guide area 22 is larger due to the upwardly lifted bottom surface, and cannot support the flange.

[0057] Furthermore, a grid-like reinforcing rib structure is provided at the rear end of the oil pan body 1 and supported between the flange plate 14 and the upper flange surface to improve the strength of the gearbox housing after installation.

[0058] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0059] Based on the same inventive concept, the embodiment of the present application further provides a vehicle, including the oil pan. Since the bolt installation position where the crankshaft pulley interferes is moved downward, the installation of the oil pan is simple and quick, which is conducive to improving installation efficiency and reducing labor intensity.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
