Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to an oil pan assembly, an engine and a vehicle. Background Art

[0002] At present, the oil pan is an important component of the engine as a container for lubricating oil. The oil pan is divided into a deep cavity and a shallow cavity. The oil pump filter is placed in the deep cavity to extract oil, which requires the oil capacity in the oil pan to be higher than the filter screen of the filter by a certain distance. When the vehicle is driving, the oil level in the oil pan fluctuates due to factors such as slope and driver operation, so that the filter screen of the filter is exposed to the oil surface, which will cause the filter to absorb too little oil, making it difficult to ensure the pressure and flow of the lubrication system.

[0003] In the related art, a mounting flange is connected to a motor or a gearbox, and the mounting flange is arranged on an oil pan, so that the mounting flange can protect the oil pan. Usually, an aluminum alloy oil pan with a mounting flange is designed as a scoop-shaped structure, and the flange end face is connected to the outer end of the oil storage tank of the oil pan. After the connection, reinforcing ribs are provided on the back to meet the connection strength between the flange end face and the oil storage tank. However, such a setting will cause the overall design structure of the oil pan to become larger, thereby compressing the oil volume and further affecting the performance of the engine.

DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0022] Reference below Figure 1-Figure 3 The oil sump assembly 100 according to an embodiment of the present invention is described, and the oil sump assembly 100 is applied to a vehicle, for example, an engine.

[0023] like Figure 1-Figure 3 As shown, the oil pan assembly 100 according to the present invention includes: a mounting flange 20 and an oil pan 10, the mounting flange 20 is suitable for connecting with an external mechanism, the mounting flange 20 is arranged on the side wall of the oil pan 10, and the bottom of the oil pan 10 is provided with a plurality of step portions 13 extending toward the mounting flange 20 and connected in sequence; the mounting flange 20 is connected to the step portion 13 at the rear end. It can be understood that the mounting flange 20 and the oil pan 10 constitute the main structure of the oil pan assembly 100, and the mounting flange 20 can be connected to an external mechanism. The mounting flange 20 is located on one side of the oil pan 10, so that the oil pan 10 can be connected to the external mechanism through the mounting flange 20. A step portion 13 is provided at the bottom of the oil pan 10, and the step portion 13 extends in the direction of the mounting flange 20, so that the number of reinforcing ribs provided on the oil pan 10 can be reduced, thereby reducing the structural size of the oil pan 10, and the step portion 13 can also improve the structural strength of the oil pan 10. The mounting flange 20 is connected to the step portion 13 at the rear end, so that the connection strength between the mounting flange 20 and the oil pan 10 can be improved, thereby improving the performance of the engine.

[0024] Therefore, by setting a step portion 13 at the bottom of the oil retaining cavity 12 in the oil pan 10, the structural strength of the oil pan 10 can be improved, and the mounting flange 20 is connected to the step portion 13, so that the connection strength between the mounting flange 20 and the oil pan 10 can be improved, and the arrangement of the reinforcing ribs can be reduced, thereby reducing the structural size of the oil pan 10. Such a setting can ensure the oil volume in the oil pan 10 and improve the performance of the engine.

[0025] Among them, Figure 3 As shown, the plurality of step portions 13 are formed with at least two step surfaces 17, and the height difference between two adjacent step surfaces 17 is h, h≥9mm, and the height difference between two adjacent step surfaces 17 cannot be too small, otherwise the step portion 13 will tend to be flat, thereby affecting the structural strength of the mounting flange 20 and the oil pan 10. For example, in order to ensure the structural strength of the mounting flange 20 and the oil pan 10, h is 9mm, 9.1mm, 9.2mm, or 9.3mm. Consider selecting a suitable parameter in the specific design.

[0026] The height difference between two adjacent step surfaces 17 is h, h≤10mm. The height difference between two adjacent step surfaces 17 cannot be too large. If it is too large, the height difference between the step portions 13 will be too large, thereby affecting the flow of the oil in the oil retaining cavity 12, and further affecting the performance of the engine. For example, in order to ensure the performance of the engine, h is 9.7mm, 9.8mm, 9.9mm, or 10mm. Consider selecting a suitable parameter in the specific design.

[0027] The height difference between two adjacent step surfaces 17 is h, and the value range of h is: 9mm≤h≤10mm. The height difference between two adjacent step surfaces 17 should be within a reasonable range, so as to ensure the structural strength of the mounting flange 20 and the oil pan 10, and also reduce the structural size of the oil pan 10, thereby ensuring the capacity of the oil pan 10 and improving the performance of the engine.

[0028] In particular, if Figure 3 As shown, the oil pan 10 is further provided with a reinforcement portion 14, and the reinforcement portion 14 is provided on at least one step portion 13. That is, the reinforcement portion 14 is located on the bottom surface of the oil pan 10, and the reinforcement portion 14 is close to the step portion 13, so that the structural strength of the mounting flange 20 and the oil pan 10 can be improved, and the volume of the oil retaining cavity 12 will not be affected, thereby improving the performance of the engine.

[0029] In addition, if Figure 2As shown, the oil pan assembly 100 further includes: an oil drain hole 30, which is arranged on the side wall of the oil pan 10, and the bottom part of the oil pan 10 is recessed downward to form a recessed portion, and the oil drain hole 30 is connected to the recessed portion, and the oil drain hole is arranged corresponding to the lowest point of the recessed portion. It can be understood that the oil drain hole 30 is located on one side of the oil pan 10, and the bottom of the oil pan 10 is arranged as a downwardly recessed arc surface, so that the oil in the oil pan 10 can be affected by gravity and tilted toward the lowest point of the arc surface, and the volume of the oil pan 10 can also be increased. Moreover, the oil drain hole 30 is located at the lowest point of the arc surface, so that the oil can flow out through the oil drain hole 30. Such an arrangement can ensure that the oil in the oil pan 10 flows out as much as possible, and thus the cleanliness of the oil pan 10 can be ensured.

[0030] Among them, Figure 2 and Figure 3 As shown, the bottom surface of the oil pan 10 is also configured as a horizontal surface, and the outer surface of the recessed portion is configured as an arc surface, the radius of the arc surface is R, and the relationship between R is: R=X 2 / 8L+L / 2; wherein X is the length of the oil pan 10, and L is the maximum distance between the arc surface and the horizontal plane 16. That is, the bottom reference plane of the oil pan 10 is set in the horizontal direction, and the arc surface is bent relative to the reference plane, so that the oil can flow out through the arc surface and the oil drain hole 30.

[0031] Alternatively, if Figure 2 As shown, the value range of L is: 5mm≤L≤10mm, and the maximum distance between the arc surface and the horizontal plane should be within a reasonable range. If the maximum distance between the arc surface and the horizontal plane is too small, the volume of the oil pan 10 will be reduced, and the engine oil will not be able to flow out completely from the oil drain hole 30, thereby affecting the maintenance and maintenance of the oil pan 10. If the maximum distance between the arc surface and the horizontal plane is too large, the volume of the oil pan 10 will be too large, resulting in a waste of engine oil and further a waste of cost. If the maximum distance between the arc surface and the horizontal plane is within a reasonable range, the volume of the oil pan 10 can be guaranteed, and the engine oil can also flow out completely from the oil drain hole 30, thereby facilitating the maintenance of the oil pan 10 and ensuring the performance of the engine.

[0032] In addition, if Figure 1 and Figure 2As shown, the oil pan assembly 100 further includes: an oil baffle 40, which is arranged in the oil pan 10 to divide the oil pan 10 into an oil storage chamber 11 and an oil baffle chamber 12, and a step portion 13 is arranged at the bottom of the oil baffle chamber 12. That is to say, the oil baffle 40 is arranged inside the oil pan 10, so that the oil baffle 40 can divide the space inside the oil pan 10 into the oil storage chamber 11 and the oil baffle chamber 12, and the engine oil flows in the oil storage chamber 11 and the oil baffle chamber 12. Such an arrangement can reduce the range of movement of the engine oil in the oil pan 10, and the step portion 13 corresponds to the oil baffle chamber 12, so that the number of reinforcing ribs arranged on the oil pan 10 corresponding to the oil baffle chamber 12 can be reduced, and the volume inside the oil pan 10 will not be changed, so that the design height of the oil pan 10 can be reduced under the same engine oil volume and engine oil movement range, thereby saving costs and ensuring the performance of the engine.

[0033] Among them, Figure 2 As shown, the oil baffle member 40 includes: a first oil baffle portion 41 and a second oil baffle portion 42, the first oil baffle portion 41 is arranged in the oil baffle cavity 12, the first oil baffle portion 41 is fixed to the oil pan 10, and the first oil baffle portion 41 extends in a horizontal direction, the second oil baffle portion 42 is connected to the first oil baffle portion 41, and the second oil baffle portion 42 extends downward in a vertical direction. It can be understood that the first oil baffle portion 41 is located in the oil baffle chamber 12, and one end of the first oil baffle portion 41 is connected to the oil pan 10, and the other end is connected to the second oil baffle portion 42, and the second oil baffle portion 42 is bent downward relative to the first oil baffle portion 41, so that the first oil baffle portion 41 and the second oil baffle portion 42 can form an "L" shape. This arrangement can divide the oil pan 10 into the oil baffle chamber 12 and the oil storage chamber 11, thereby reducing the range of movement of the engine oil without affecting the volume in the oil pan 10, so that the design height of the oil pan 10 can be reduced under the same engine oil volume and engine oil activity range, and the first oil baffle portion 41 is horizontally arranged, and the second oil baffle portion 42 is vertically arranged, so that the oil baffle member 40 can block the lateral and longitudinal movement of the engine oil, but the first oil baffle portion 41 and the second oil baffle portion 42 can also extend at an angle. For example, when the vehicle is going uphill, downhill or making an emergency stop, the oil hits the oil pan 10 due to inertia. The shaking of the oil will increase the risk of the oil pump sucking empty. The oil baffle 40 can reduce the movement range of the oil, thereby ensuring that there is sufficient oil around the oil pump. It can also prevent a large amount of oil from moving and being stirred by the crankshaft to generate bubbles, which makes it difficult for the bubbles in the oil to be absorbed by the oil pump, thereby affecting the performance of the engine.

[0034] In addition, Figure 1As shown, the oil pan 10 is provided with an oil pump sprocket sealing groove 15 at the position corresponding to the oil storage cavity 11, and the oil pump sprocket sealing groove 15 is suitable for cooperating and sealing with the U-shaped structure on the oil pump. In other words, the oil pan 10 is provided with an oil pump sprocket sealing groove 15, and the oil pump sprocket sealing groove 15 is located on the side of the oil storage cavity 11 away from the oil retaining cavity 12, so that the oil pump sprocket sealing groove 15 is convenient for cooperating and sealing with the U-shaped structure on the oil pump. Such a setting can eliminate the setting of the oil pump sprocket cover, thereby making the design of the oil pan 10 more compact and miniaturized.

[0035] The engine according to the present invention includes: the oil pan assembly 100 of the above embodiment, by setting a step portion 13 at the bottom of the oil retaining cavity 12 in the oil pan 10, the structural strength of the oil pan 10 can be improved, and the mounting flange 20 is fixed to the step portion 13, so that the connection strength between the mounting flange 20 and the oil pan 10 can be improved, and the arrangement of the reinforcing ribs can be reduced, thereby reducing the structural size of the oil pan 10. Such a setting can ensure the oil volume in the oil pan 10 and improve the performance of the engine.

[0036] The vehicle according to the present invention comprises: the engine of the above embodiment. Such an arrangement can ensure the oil volume in the oil pan 10 and improve the performance of the engine.
