Description

Technical Field

[0001] The utility model relates to the technical field of oil filters, in particular to an oil filter housing structure. Meanwhile, the utility model also relates to an oil filter provided with the oil filter housing structure, and a vehicle provided with the oil filter. Background Art

[0002] At present, the suction oil filter of the automatic transmission is mainly used to filter the oil, and there are three main types: flat, integrated and cylindrical. Among them, the flat oil filter is the most widely used, and it is mainly composed of sealing rings, upper covers, lower covers, filter paper, magnets, bushings and other parts. When the transmission oil pump is running, negative pressure is generated at the oil outlet, causing the oil to enter the interior from the oil suction port. After the oil is filtered by the filter paper inside, it flows out from the oil outlet and enters the hydraulic system through the oil pump drive. Therefore, the oil inlet needs to be immersed below the oil level under any working conditions.

[0003] The oil inlet of the suction filter is usually arranged at the bottom of the oil, but in some extreme cases of the vehicle's operating conditions, as the oil level changes, the oil inlet will be exposed, causing the oil pump to inhale air, causing the vehicle to drop pressure and vibrate, and the pump to make abnormal noises. Therefore, in order to prevent the oil pump from inhaling air, the method of adding more oil is often used, but this method will obviously increase the overall weight of the transmission. Utility Model Content

[0004] In view of this, the utility model aims to provide an oil filter housing structure, so as to effectively prevent the oil pump connected to the oil outlet of the oil filter from inhaling air.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] An oil filter housing structure comprises a housing body and an adjustment mechanism arranged on the housing body;

[0007] The shell body has a filter cavity, and an oil inlet and an oil outlet communicated with the filter cavity, and the oil inlet includes oil inlets arranged at both ends of the shell body;

[0008] The regulating mechanism comprises a main body rotatably arranged on the shell body, and regulating members arranged on two opposite sides of the main body, and the main body is located outside the filter cavity and arranged between the oil inlets at both ends;

[0009] The adjusting members on each side correspond to the oil inlets at the corresponding ends one by one, and the main body is driven to rotate by the oil, so that the adjusting member on one side can block the oil inlet on the corresponding side.

[0010] Furthermore, the regulating member includes a connecting rod connected to the main body, and a sphere disposed on the connecting rod, and the sphere is used to block the oil inlet.

[0011] Furthermore, the shell body is rectangular, and the rotation axis of the main body is arranged at an acute angle with the length direction of the shell body.

[0021] The oil filter housing structure described in the utility model is provided with an adjusting mechanism, and the adjusting mechanism includes a main body rotatably arranged on the housing body, and adjusting members arranged on two opposite sides of the main body. Therefore, when the vehicle is in an extreme working condition, the main body can be driven to rotate the adjusting member by the surge of oil, so that the adjusting member can block the oil inlet that exposes the oil, thereby preventing the oil pump from sucking air from the exposed oil inlet, without the need to increase the oil volume in the traditional way, and the weight of the gearbox can be reduced.

[0022] In addition, the adjusting member includes a connecting rod connected to the main body and a sphere arranged on the connecting rod, and has a simple structure. The sphere abuts against the oil inlet through its arc-shaped outer surface, which can improve the sealing effect of the adjusting member on the oil inlet. The rotation axis of the main body and the length direction of the shell body are set at an acute angle, which is conducive to driving the main body to drive the sphere to rotate, thereby ensuring the sealing effect of the adjusting member on the oil inlet exposed to the oil.

[0023] Secondly, the oil inlets are arranged at two opposite ends of the shell body, with a simple structure, easy to design and implement, and can ensure that at least one of the oil inlets of the vehicle is located in the oil under any extreme working conditions to ensure the oil inlet effect.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0048] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0049] In the prior art, the oil inlet 1011 of the suction oil filter is generally arranged at the bottom of the oil, but in certain extreme conditions of the vehicle working condition, as the oil level changes, the oil inlet 1011 may be exposed, causing the oil pump to inhale air, which may cause the whole vehicle to drop pressure and vibrate, and the pump to make abnormal noises. Therefore, in order to prevent the oil pump from inhaling air, the method of adding more oil is often used, but this method will obviously increase the overall weight of the transmission.

[0050] To this end, this embodiment particularly proposes a novel oil filter housing structure, including a housing body 1, and an adjustment mechanism disposed on the housing body 1. The housing body 1 has a filter cavity, and an oil inlet and an oil outlet connected to the filter cavity, and the oil inlet includes oil inlets 1011 disposed at both ends of the housing body 1. The adjustment mechanism includes a main body rotatably disposed on the housing body 1, and adjustment members disposed on two opposite sides of the main body, and the main body is located outside the filter cavity and disposed between the oil inlets 1011 at both ends, and the adjustment members on each side correspond to the oil inlets 1011 at the corresponding end, and the main body is driven to rotate by oil, so that the adjustment member on one side can block the oil inlet 1011 on the corresponding side.

[0051] The oil filter housing structure of this embodiment is provided with an adjustment mechanism, and the adjustment mechanism includes a main body rotatably arranged on the housing body 1, and adjustment members arranged on two opposite sides of the main body. Therefore, when the vehicle is in an extreme working condition, the main body can be driven to drive the adjustment member to rotate by the surge of oil, so that the adjustment member can block the oil inlet 1011 exposed to the oil, thereby preventing the oil pump from sucking air from the exposed oil inlet 1011, without the need to increase the oil volume in the traditional way, and can reduce the weight of the gearbox.

[0052] Based on the above overall introduction, an exemplary structure of the oil filter housing structure of this embodiment is referred to as follows: Figures 1 to 6 As shown, as a preferred embodiment, the housing body 1 of this embodiment is rectangular as a whole. In this embodiment, the housing body 1 is set to be rectangular, which is not only convenient for processing and manufacturing, but also convenient for its arrangement in the gearbox. Of course, in specific implementation, the shape of the housing body 1 can be adaptively adjusted.

[0053] As a preferred embodiment, Figure 3 and Figure 7 As shown, a partition 103 is provided inside the shell body 1 of this embodiment, and the partition 103 divides the filter chamber into an oil inlet chamber 101a and an oil outlet chamber 101b, and a connecting portion connecting the oil inlet chamber 101a and the oil outlet chamber 101b is provided on the partition 103. The oil inlet portion is connected to the oil inlet chamber 101a, and the oil outlet portion is connected to the oil outlet chamber 101b, and the oil outlet chamber 101b is used to install the filter element 5, and the oil outlet portion and the connecting portion are respectively arranged near the two opposite ends of the shell body 1. In this embodiment, by making the oil outlet portion and the connecting portion respectively arranged near the two opposite ends of the shell body 1, the oil in the filter chamber can be fully filtered by the internal filter element 5, and the cleanliness of the oil sucked out from the oil outlet 1021 can be improved.

[0054] In addition, as a preferred embodiment, Figure 7 As shown, for the convenience of processing and manufacturing, the communication part of this embodiment includes a communication port 1031 provided on the partition 103, while the oil inlet part includes two oil inlets 1011, and the oil outlet part includes only one oil outlet 1021. Moreover, the two oil inlets 1011 are respectively provided at two opposite ends of the shell body, and the connecting line between the two oil inlets 1011 is perpendicular to the rotation axis of the body. Such an arrangement enables the vehicle to have at least one of its oil inlets 1011 located in the oil liquid under any extreme working conditions to ensure the oil inlet effect.

[0055] Furthermore, in order to facilitate the oil outlet 1021 to be connected to the oil pump, as shown in FIG. Figure 7As shown, an oil outlet pipe is provided on the housing body 1, and the oil outlet 1021 is formed on the oil outlet pipe. It should be noted that the number of the connecting port 1031, the oil inlet 1011 and the oil outlet 1021 can be adjusted accordingly according to the design requirements. In addition, in order to facilitate the installation of the filter element 5, as shown in FIG. Figure 7 As shown, as a preferred embodiment, the shell body 1 of this embodiment includes a first shell 101 and a second shell 102 which are detachably connected, and a filter cavity is formed between the two.

[0056] The oil inlet is arranged on the first housing 101, and the oil outlet is arranged on the second housing 102. In addition, the first housing 101 and the second housing 102 can be connected by conventional means such as snap connection or screw connection. The specific structure can refer to the prior art and will not be described in detail here. In addition, to ensure the sealing of the filter cavity, a sealing gasket is usually sandwiched between the first housing 101 and the second housing 102. The filter element 5 can adopt conventional structures such as existing filter screens or filter paper, which will not be described here.

[0057] Combination Figure 8 and 9 As shown in , as a preferred embodiment, there are two adjusting members arranged one-to-one corresponding to the oil inlet 1011, and the two adjusting members are arranged in a V shape. Such an arrangement can prevent the adjusting members from interfering with the shell body 1. And, as a preferred embodiment, the main body is rotatably arranged on the first shell 101 through the rotating shaft 6, and in order to prevent the main body and the adjusting member from interfering with the first shell 101 during the rotation process, the outer diameter of the rotating shaft 6 is relatively large. In addition, in order to realize the connection between the rotating shaft 6 and the first shell 101, for example, an axial hole can be set in the middle of the rotating shaft 6, and an insert shaft inserted into the axial hole can be set on the first shell 101.

[0058] The regulating member of this embodiment includes a connecting rod 3 connected to the main body, and a sphere 4 arranged on the connecting rod 3, and the sphere 4 is used to block the oil inlet 1011. The regulating member of this embodiment adopts this structure, which has the advantages of simple structure and easy processing and manufacturing. Moreover, the sphere 4 abuts against the oil inlet 1011 through its arc-shaped outer surface, which can improve the sealing effect of the regulating member on the oil inlet 1011.

[0059] In addition, based on the fact that the oil inlet portion includes only two oil inlets 1011, the connecting rod 3 and the ball 4 of this embodiment are also two arranged in a one-to-one correspondence with the two oil inlets 1011. In addition, as a further embodiment, Figure 6 As shown in , the rotation axis of the main body is set at an acute angle with the length direction of the shell body 1. This design can facilitate the rotation of the push main body when the vehicle is under extreme working conditions to ensure the blocking effect of the regulating member on the oil inlet 1011 exposed to the oil.

[0060] Combination Figure 3 , Figure 8 and Fig. 9 As shown in , the main body of this embodiment includes a main board 2 rotatably disposed on the shell body 1, and the main board 2 extends along the rotation axis of the main body. In this embodiment, by making the main body include the main board 2 rotatably disposed on the shell body 1, and the main board 2 extends along the rotation axis of the main body, the main body and the oil can have a larger contact area, which is conducive to receiving the top push of the oil to drive the adjustment member to rotate.

[0061] Based on the above overall description, when the vehicle is traveling at a constant speed and in a straight line on a flat road, the oil pump applies negative pressure from the oil outlet 1021, and the oil in the transmission housing is collected to the connecting port 1031 through the two oil inlets 1011 and enters the oil outlet chamber 101b. The oil is filtered by the filter element 5 in the oil outlet chamber 101b, and the filtered oil enters the oil pump from the oil outlet 1021 to work.

[0062] Reference Fig.10 The oil flow path shown by the middle dotted line is that when the vehicle is accelerating rapidly, the oil flows backward due to inertia, or when turning right, the oil flows to the left side of the vehicle. At this time, the oil impacts the left side of the main board 2 in a clockwise manner, and the main board 2 starts to rotate. When the left ball 4 of the adjustment member blocks the left oil inlet 1011, the oil can only enter the inside of the suction filter from the right oil inlet 1011. Then, it enters the oil outlet chamber 101b from the connecting port 1031. After the oil passes through the filter 5, the filtered oil enters the oil outlet 1021 and enters the oil pump to work.

[0063] And refer to Fig.11 The oil flow path shown by the middle dotted line is that when the vehicle is decelerating suddenly, the oil surges forward due to inertia, or when turning left, the oil surges to the right. At this time, the oil impacts the right side of the main board 2 in the reverse direction, and the main board 2 starts to rotate. When the ball 4 on the right side of the adjustment member blocks the right oil inlet 1011, the oil can only enter the suction filter from the left oil inlet 1011. Then, it enters the oil outlet chamber 101b from the connecting port 1031. After the oil passes through the filter 5, the filtered oil enters the oil outlet 1021 and enters the oil pump to work.

[0064] It can be seen that the oil filter housing structure of this embodiment can effectively reduce the probability of the oil pump sucking air by adopting the above structure, thereby reducing the probability of abnormal noise and vehicle shaking. In addition, the amount of oil in the gearbox can be reduced, thereby reducing the overall weight of the gearbox and reducing costs.

[0065] Another purpose of this embodiment is to provide an oil filter, which includes the above oil filter housing structure.

[0066] The oil filter of this embodiment has all the beneficial effects of the above-mentioned oil filter housing structure, which will not be described in detail here.

[0067] In addition, another object of this embodiment is to provide a vehicle, on which the above oil filter is provided.

[0068] The vehicle of this embodiment, by providing the above-mentioned oil filter, can effectively ensure that no air enters the oil inlet 1011 under any operating condition of the vehicle, and can effectively solve the risk of the oil pump sucking in air; moreover, there is no need to increase the amount of oil to prevent the oil filter from entering air, thereby reducing the weight of the gearbox.

[0069] 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, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
