Description

Gear pump filler, gear pump, suspension assembly and vehicle

[0001] This application claims priority to Chinese Patent Application No. 202411005412.4, filed on July 24, 2024, entitled "Gear Pump Filler, Gear Pump, Suspension Assembly and Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0003] In related technologies, a filler is generally provided between the gear and the gear ring of an internal gear pump. The filler is used to divide the chamber between the gear and the gear ring into a high-pressure chamber and a low-pressure chamber to ensure that the fluid in the internal gear pump flows in a predetermined direction. Technical issues

[0004] However, when the pressure in the high-pressure chamber of the internal gear pump is high, the packing material is subjected to unbalanced forces, which can easily squeeze the part of the packing material near the gear ring to the gear ring.

[0058] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0059] According to one embodiment of this application, a gear pump filler 30 is provided. Referring to Figures 1 to 7, the gear pump filler 30 is configured to fill between a gear ring 10 and a gear 9 internally meshed with the gear ring 10. The gear pump filler 30 includes a first crescent plate 1. The first crescent plate 1 includes a first connecting portion 102, a first main crescent plate 101 configured to abut against the outside of the gear 9, and a first secondary crescent plate 103 configured to abut against the inside of the gear ring 10. The first connecting portion 102 is disposed between the first main crescent plate 101 and the first secondary crescent plate 103.

[0060] Specifically, as shown in Figures 1 and 2, the gear pump 31 of this embodiment includes a gear ring 10 and a gear 9 internally meshed with the gear ring 10. A first crescent plate 1 fills the space between the gear ring 10 and the gear 9 internally meshing with the gear ring 10, that is, the first main crescent plate 101 abuts against the outer side of the gear 9. A first secondary crescent plate 103 abuts against the inner side of the gear ring 10 to divide the fluid space between the gear ring 10 and the gear 9 into a first fluid chamber 11 enclosed by the first crescent plate 1 and the gear 9, and a second fluid chamber 12 enclosed by the first crescent plate 1 and the gear ring 10. The first crescent plate 1 includes a first connecting portion 102. The first connecting portion 102 connects the first main crescent plate 101, configured to abut against the outer side of the gear 9, and the first secondary crescent plate 103, configured to abut against the inner side of the gear ring 10.

[0061] Therefore, when the hydraulic oil in the first fluid chamber 11 presses the first secondary meniscus 103 against the gear ring 10, the first connecting portion 102, which connects the first secondary meniscus 103 and the first primary meniscus 101, can transmit the pressure on the first secondary meniscus 103 to the first primary meniscus 101, allowing the first primary meniscus 101 to move toward the gear 9. This effectively reduces the contact area between the first secondary meniscus 103 and the gear ring 10, significantly reducing the risk of wear on the first secondary meniscus 103.

[0062] In one embodiment, the gear pump filler 30 further includes a second crescent plate 2. The second crescent plate 2 includes a second connecting portion 202, a second main crescent plate 201, and a second auxiliary crescent plate 203. The second connecting portion 202 is disposed between the second main crescent plate 201 and the second auxiliary crescent plate 203. The first connecting portion 102 and the second connecting portion 202 are rotatably engaged. The first crescent plate 1 and the second crescent plate 2 are alternately arranged.

[0063] Specifically, as shown in Figures 1 to 6, in this embodiment of the application, the first crescent plate 1 and the second crescent plate 2 are staggered, that is, the first main crescent plate 101 and the second secondary crescent plate 203 are radially spaced apart (i.e., the first main crescent plate 101 is located between the second secondary crescent plate 203 and the gear 9), and the second main crescent plate 201 and the first secondary crescent plate 103 are radially spaced apart (i.e., the second main crescent plate 201 is located between the first secondary crescent plate 103 and the gear 9). Therefore, after the first connecting part 102 and the second connecting part 202 are rotatably connected, the first main crescent plate 101 and the second main crescent plate 201 can abut against the outside of the gear 9, and the first secondary crescent plate 103 and the second secondary crescent plate 203 can abut against the inside of the gear ring 10, so as to divide the fluid space between the gear 9 and the gear ring 10 into a first fluid chamber 11 enclosed by the gear pump filler 30 and the gear 9 and a second fluid chamber 12 enclosed by the gear pump filler 30 and the gear ring 10.

[0064] The gear 9 also includes a drive shaft 15. The drive shaft 15 is connected to a motor. The motor can drive the drive shaft 15 to rotate the gear 9 clockwise or counterclockwise.

[0065] Therefore, as shown in Figures 1 and 2, when the motor drives the gear 9 to rotate counterclockwise, the chamber between the gear 9 and the gear ring 10 is further divided into a first chamber 13 and a second chamber 14. The first chamber 13 is a low-pressure chamber. The second chamber 14 is a high-pressure chamber. Hydraulic oil is provided in both the first chamber 13 and the second chamber 14. Of course, lubricating oil, engine oil, water, or water-based liquids can also be provided in the first chamber 13 and the second chamber 14. Those skilled in the art can choose according to actual needs, and this application does not impose specific limitations here.

[0066] At this time, since the gear pump filler 30 is also provided between the gear 9 and the gear ring 10, the first chamber 13 is further divided by the gear pump filler 30 into a first fluid chamber 11 enclosed by the gear pump filler 30 and the gear 9, and a second fluid chamber 12 enclosed by the gear pump filler 30 and the gear ring 10. Furthermore, since the motor drives the gear 9 to rotate continuously counterclockwise, the hydraulic oil in the first fluid chamber 11 and the hydraulic oil in the second fluid chamber 12 can flow into the high-pressure second chamber 14, and then be squeezed out of the second chamber 14 by the meshing of the gear 9 and the gear ring 10.

[0067] However, since there is a second gap 4 between the second main crescent plate 201 and the first secondary crescent plate 103, when the hydraulic oil in the first chamber 13 flows into the second chamber 14, there will be more hydraulic oil entering the second gap 4 to fill it. Furthermore, the hydraulic oil can also apply a force to the first main crescent plate 101 in the direction of the gear 9 and a force to the second secondary crescent plate 203 in the direction of the gear ring 10, which gradually increases the contact area between the second secondary crescent plate 203 and the gear ring 10, thus increasing the risk of wear on the second secondary crescent plate 203.

[0068] Furthermore, in this embodiment, the staggered arrangement of the first crescent plate 1 and the second crescent plate 2 creates a first gap 3 between the first main crescent plate 101 and the second auxiliary crescent plate 203. Thus, when the first main crescent plate 101 moves toward the gear 9 and the second auxiliary crescent plate 203 moves toward the gear ring 10, due to the rotational engagement of the first connecting part 102 and the second connecting part 202, the second main crescent plate 201 can also move toward the gear 9, and the first auxiliary crescent plate 103 can also move toward the gear ring 10. This allows the compressive force on the first main crescent plate 101 and the second auxiliary crescent plate 203 to be transmitted to both, ensuring that the size of the first gap 3 gradually increases with the size of the second gap 4. This effectively reduces the contact area between the second auxiliary crescent plate 203 and the gear ring 10, significantly reducing the risk of wear on the second auxiliary crescent plate 203.

[0069] Furthermore, as shown in Figures 1 and 2, when the motor drives the gear 9 to rotate clockwise, the first chamber 13 is a high-pressure chamber, and the second chamber 14 is a low-pressure chamber. This allows the hydraulic oil to first apply a force to the second main crescent plate 201 moving towards the gear 9 and to the first auxiliary crescent plate 103 moving towards the gear ring 10. This causes the contact area between the first auxiliary crescent plate 103 and the gear ring 10 to gradually increase. Then, the first connecting part 102 and the second connecting part 202 rotate and engage, allowing the compressive force on the second main crescent plate 201 and the first auxiliary crescent plate 103 to be transmitted to both. This results in the size of the second gap 4 gradually increasing with the size of the first gap 3. This effectively reduces the contact area between the first auxiliary crescent plate 103 and the gear ring 10, significantly reducing the risk of wear on the first auxiliary crescent plate 103.

[0070] Furthermore, since the first crescent plate 1 and the second crescent plate 2 of the gear pump filler 30 described in this application embodiment are separate structures, when the hydraulic oil in the low-pressure chamber and the hydraulic oil in the high-pressure chamber generate different pressures, the part of the gear pump filler 30 in the low-pressure chamber will not only not lift up under the pressure of the hydraulic oil in the high-pressure chamber, but will also fit the gear 9 more closely, thereby further improving the internal sealing effect of the internal meshing gear pump 31.

[0071] In one embodiment, a first groove 1011 is provided between the first main crescent plate 101 and the second secondary crescent plate 203. The gear pump filler 30 further includes a first elastic member 5 and a first sealing member 6. The first elastic member 5 is disposed in the first groove 1011. The first elastic member 5 can abut the first sealing member 6 against the first main crescent plate 101 and the second secondary crescent plate 203 respectively, so as to seal the first gap 3 between the first main crescent plate 101 and the second secondary crescent plate 203.

[0072] Specifically, as shown in Figures 3 and 4, in this embodiment of the application, the abutting surfaces of the first main crescent plate 101 and the second secondary crescent plate 203 are provided with a first groove 1011. The first elastic member 5 can be fixed to the first groove 1011, so that when the first sealing member 6 is disposed between the first elastic member 5 and the second secondary crescent plate 203, the first elastic member 5 can apply a force to the first sealing member 6 to move towards the second secondary crescent plate 203, so that the first sealing member 6 abuts against the first main crescent plate 101 and the second secondary crescent plate 203 respectively, to seal the first gap 3 between the first main crescent plate 101 and the second secondary crescent plate 203, thereby effectively preventing the oil in the second chamber 14 from entering the rotational fit between the first crescent plate 1 and the second crescent plate 2 through the first gap 3, which would cause the rotational fit between the first crescent plate 1 and the second crescent plate 2 to fail, significantly improving the stability and reliability of the gear pump filler 30 and extending the service life of the gear pump filler 30.

[0073] In this embodiment, the first groove 1011 can be a triangular groove, a rectangular groove, or a trapezoidal groove, etc. The first elastic element 5 can be a spring, a leaf spring, or a rubber pad, etc. Those skilled in the art can choose according to actual needs, and this application does not impose specific limitations.

[0074] Furthermore, in this embodiment, the first sealing element 6 can be a cylindrical sealing rod or an irregular cylindrical sealing rod. Of course, provided that the sealing between the first main crescent plate 101 and the second secondary crescent plate 203 is satisfied, the first sealing element 6 can also be a prismatic sealing rod or an irregular prismatic sealing rod, etc. Those skilled in the art can choose according to actual needs, and this application does not impose specific limitations here.

[0075] Furthermore, in this application embodiment, the connection between the first elastic element 5 and the first sealing element 6, as well as the connection between the first elastic element 5 and the second crescent plate 203, can be achieved through bonding or welding, etc. Those skilled in the art can choose according to actual needs, and this application does not impose specific limitations here.

[0076] In one embodiment, a second groove 2011 is provided between the second main crescent plate 201 and the first secondary crescent plate 103. The gear pump filler 30 further includes a second elastic member 7 and a second sealing member 8. The second elastic member 7 is disposed in the second groove 2011. The second elastic member 7 can abut the second sealing member 8 against the second main crescent plate 201 and the first secondary crescent plate 103 respectively, so as to seal the second gap 4 between the second main crescent plate 201 and the first secondary crescent plate 103.

[0077] Specifically, as shown in Figures 5 and 6, in this embodiment of the application, the contact surface between the second main crescent plate 201 and the first secondary crescent plate 103 is provided with a second groove 2011. The second elastic member 7 can be fixed to the second groove 2011, so that when the second sealing member 8 is disposed between the second elastic member 7 and the first secondary crescent plate 103, the second elastic member 7 can apply a force to the second sealing member 8 to move towards the first secondary crescent plate 103, so that the second sealing member 8 abuts against the second main crescent plate 201 and the first secondary crescent plate 103 respectively, to seal the second gap 4 between the second main crescent plate 201 and the first secondary crescent plate 103, thereby effectively preventing the oil in the first chamber 13 from entering the rotational fit between the first crescent plate 1 and the second crescent plate 2 from the second gap 4, which would cause the rotational fit between the first crescent plate 1 and the second crescent plate 2 to fail, significantly improving the stability and reliability of the gear pump filler 30 and extending the service life of the gear pump filler 30.

[0078] In this embodiment, the second groove 2011 can be a triangular groove, a rectangular groove, or a trapezoidal groove, etc. The second elastic element 7 can be a spring, a leaf spring, or a rubber pad, etc. Those skilled in the art can choose according to actual needs, and this application does not impose specific limitations here.

[0079] Furthermore, in this embodiment, the second sealing element 8 can be a cylindrical sealing rod or an irregular cylindrical sealing rod. Of course, provided that the sealing between the second main crescent plate 201 and the first secondary crescent plate 103 is satisfied, the second sealing element 8 can also be a prismatic sealing rod or an irregular prismatic sealing rod, etc. Those skilled in the art can choose according to actual needs, and this application does not impose specific limitations here.

[0080] Furthermore, in the embodiments of this application, the connection between the second elastic element 7 and the second sealing element 8, as well as the connection between the second elastic element 7 and the first crescent plate 103, can be bonding or welding, etc. Those skilled in the art can choose according to actual needs, and this application does not impose specific limitations here.

[0081] In one embodiment, the first connecting portion 102 includes a first rotating portion 1021 and a first extending portion 1022. The dimension of the first rotating portion 1021 along the first direction is smaller than the dimension of the first extending portion 1022 along the first direction. The second connecting portion 202 includes a second rotating portion 2021 and a second extending portion 2022. The dimension of the second rotating portion 2021 along the first direction is equal to the dimension of the second extending portion 2022 along the first direction. The first rotating portion 1021 and the second rotating portion 2021 are rotatably engaged.

[0082] Specifically, as shown in Figures 4 and 6, in this embodiment, the dimension of the first main crescent plate 101 along the first direction is equal to the dimension of the first secondary crescent plate 103 along the first direction, and the dimension of the first connecting portion 102 along the first direction is smaller than the dimension of the first main crescent plate 101 along the first direction, or the dimension of the first connecting portion 102 along the first direction is smaller than the dimension of the first secondary crescent plate 103 along the first direction. Similarly, the dimension of the second main crescent plate 201 along the first direction is equal to the dimension of the second secondary crescent plate 203 along the first direction, and the dimension of the second connecting portion 202 along the first direction is smaller than the dimension of the second main crescent plate 201 along the first direction, or the dimension of the second connecting portion 202 along the first direction is smaller than the dimension of the second secondary crescent plate 203 along the first direction. This facilitates the rotational engagement of the first crescent plate 1 and the second crescent plate 2.

[0083] The first connecting portion 102 further includes a first rotating portion 1021. The first rotating portion 1021 is provided with a first circular protrusion 10211. The second connecting portion 202 further includes a second rotating portion 2021 and a second extension portion 2022. The second rotating portion 2021 is provided with a first strip groove 20211. By setting the dimension of the first rotating portion 1021 along the first direction to be smaller than the dimension of the first extension portion 1022 along the first direction, and the dimension of the second rotating portion 2021 along the first direction to be equal to the dimension of the second extension portion 2022 along the first direction, the connection efficiency between the first crescent plate 1 and the second crescent plate 2 can be effectively improved, and the assembly efficiency of the gear pump filler 30 can also be significantly improved.

[0084] Furthermore, when the first rotating part 1021 is provided with a second strip groove, the dimension of the first rotating part 1021 along the first direction can be set to be equal to the dimension of the first extension part 1022 along the first direction, so that the first crescent plate 1 can more easily rotate and cooperate with the second crescent plate 2, thereby improving the assembly efficiency of the gear pump filler 30.

[0085] In addition, when the second rotating part 2021 is provided with a second circular protrusion, the size of the second rotating part 2021 along the first direction can be set to be smaller than the size of the second extension part 2022 along the first direction, so that the first crescent plate 1 can more easily rotate and cooperate with the second crescent plate 2, thereby improving the assembly efficiency of the gear pump filler 30.

[0086] In one embodiment, the first rotating portion 1021 includes a first circular protrusion 10211. The second rotating portion 2021 includes a first strip groove 20211. The first circular protrusion 10211 rotatably engages with the first strip groove 20211. Alternatively, the first rotating portion 1021 includes a second strip groove. The second rotating portion 2021 includes a second circular protrusion. The second circular protrusion rotatably engages with the second strip groove.

[0087] Specifically, as shown in Figures 4 and 6, in this embodiment, the first rotating part 1021 and the second rotating part 2021 can form the rotating part of the gear pump filler 30. By means of the first circular protrusion 10211 rotating with the first strip groove 20211, or by means of the second circular protrusion rotating with the second strip groove, the first crescent plate 1 can be effectively rotated relative to the second crescent plate 2 around the rotating part. Furthermore, by means of the high-pressure hydraulic oil in the internal gear pump 31 being configured as the first crescent plate 1 and the second crescent plate 2, the internal sealing effect of the internal gear pump 31 can be significantly improved.

[0088] Furthermore, the rotating part formed by the first rotating part 1021 and the second rotating part 2021 in this embodiment of the application can also reduce the thickness of the hydraulic oil film in the internal gear pump 31, and reduce the leakage flow of hydraulic oil in the locating pin gaps, the first gap 3, the second gap 4 and the third gap 16 in the internal gear pump 31.

[0089] In one embodiment, the dimension of the first extension 1022 along the first direction is smaller than the dimension of the first sub-lunar plate 103 along the first direction. Alternatively, the dimension of the second extension 2022 along the first direction is smaller than the dimension of the second sub-lunar plate 203 along the first direction. Or, the dimension of the first extension 1022 along the first direction is smaller than the dimension of the first sub-lunar plate 103 along the first direction, and the dimension of the second extension 2022 along the first direction is smaller than the dimension of the second sub-lunar plate 203 along the first direction.

[0090] Specifically, as shown in Figures 4 and 6, this embodiment of the application sets the size of the first extension 1022 along the first direction to be smaller than the size of the first secondary crescent plate 103 along the first direction, and the size of the second extension 2022 along the first direction to be smaller than the size of the second secondary crescent plate 203 along the first direction, so that the first connecting portion 102 can be better connected to the second connecting portion 202.

[0091] For example, by providing shorter first extension 1022 and second extension 2022, the first circular protrusion 10211 can be inserted into the first strip groove 20211 more conveniently, and the first circular protrusion 10211 can rotate better in the first strip groove 20211, thereby significantly improving the rotational engagement effect between the first crescent plate 1 and the second crescent plate 2.

[0092] In one embodiment, a third gap 16 is provided between the first connecting portion 102 and the second connecting portion 202. The size of the third gap 16 can be reduced to zero due to rotation of the first connecting portion 102 and the second connecting portion 202.

[0093] Specifically, as shown in Figures 1 and 2, when the first rotating part 1021 rotates to its limit position relative to the second rotating part 2021, that is, when the size of the first gap 3 and the second gap 4 is at its maximum, the first extension part 1022 can abut against the second extension part 2022, thereby reducing the third gap 16 to zero, thus effectively eliminating the third gap 16.

[0094] Therefore, when the pressure in the high-pressure chamber of the gear pump 31 is too high and squeezes the first sub-crescent plate 103 or the second sub-crescent plate 203, the rotation angle of the first rotating part 1021 relative to the second rotating part 2021 can be effectively limited, so as to further prevent the first sub-crescent plate 103 or the second sub-crescent plate 203 from being excessively lifted and thus aggravating wear.

[0095] Wherein, since there is a first gap 3 between the first main crescent plate 101 and the second secondary crescent plate 203, and a second gap 4 between the second main crescent plate 201 and the first secondary crescent plate 103, the third gap gradually decreases as the size of the first gap 3 or the second gap 4 gradually increases; and the third gap gradually increases as the size of the first gap 3 or the second gap 4 gradually decreases.

[0096] In one embodiment, the first connecting portion 102 includes a first extension 1022. The first extension 1022 is disposed on the side of the first secondary crescent plate 103 near the first primary crescent plate 101. The second connecting portion 202 includes a second extension 2022. The second extension 2022 is disposed on the side of the second secondary crescent plate 203 near the second primary crescent plate 201. The third gap 16 is provided between the first extension 1022 and the second extension 2022.

[0097] Specifically, as shown in Figures 4 and 6, in this embodiment of the application, the first extension 1022 is the extension of the first sub-lunar plate 103 toward the first main crescent plate 101. The second extension 2022 is the extension of the second sub-lunar plate 203 toward the second main crescent plate 201. The first extension 1022 allows the first sub-lunar plate 103 to be closer to the second sub-lunar plate 203. The second extension 2022 allows the second sub-lunar plate 203 to be closer to the first sub-lunar plate 103.

[0098] Therefore, by bringing the first extension 1022 and the second extension 2022 closer together, the third gap 16 between the first crescent plate 1 and the second crescent plate 2 can be effectively reduced, allowing the third gap 16 to hold a smaller volume of hydraulic oil and significantly reducing the hydraulic oil leakage flow rate of the third gap 16. Simultaneously, the embodiment of this application, through the provision of the first extension 1022, also significantly reduces the impact on the gear ring 10 at its apex, resulting in higher stability and reliability of the internal gear pump 31.

[0099] In one embodiment, the first connecting portion 102 includes a first connecting hole (not shown in the figure). The second connecting portion 202 includes a second connecting hole (not shown in the figure). The gear pump filler 30 also includes a rotating pin (not shown in the figure). One end of the rotating pin is rotatably disposed in the first connecting hole, and the other end of the rotating pin is rotatably disposed in the second connecting hole.

[0100] Specifically, in this embodiment, the rotation of the first crescent plate 1 relative to the second crescent plate 2 around the rotating part is effectively achieved by the cooperation of the rotating pin with the first connecting hole and the second connecting hole. Furthermore, the high-pressure hydraulic oil in the internal gear pump 31 acts on the first crescent plate 1 and the second crescent plate 2, which can significantly improve the internal sealing effect of the internal gear pump 31.

[0101] In one embodiment, the end face of the first main crescent plate 101 facing away from the first secondary crescent plate 103 and the end face of the second secondary crescent plate 203 facing away from the second main crescent plate 201 are located in the same plane. Alternatively, the end face of the first secondary crescent plate 103 facing away from the first main crescent plate 101 and the end face of the second main crescent plate 201 facing away from the second secondary crescent plate 203 are located in the same plane. Or, the end face of the first main crescent plate 101 facing away from the first secondary crescent plate 103 and the end face of the second secondary crescent plate 203 facing away from the second main crescent plate 201 are located in the same plane, and the end face of the first secondary crescent plate 103 facing away from the first main crescent plate 101 and the end face of the second main crescent plate 201 facing away from the second secondary crescent plate 203 are located in the same plane.

[0102] Specifically, as shown in Figures 1 and 2, after the first crescent plate 1 and the second crescent plate 2 are connected in the embodiments of this application, the edges of the first crescent plate 1 and the second crescent plate 2 are basically flush. In this way, hydraulic oil can enter the first gap 3 or the second gap 4 more quickly, thereby further reducing the risk of wear on the first secondary crescent plate 103 or the second secondary crescent plate 203.

[0103] In one embodiment, the first crescent plate 1 further includes a first raised structure 104, which is disposed at one end of the first main crescent plate 101 opposite to the first secondary crescent plate 103. The first raised structure 104 and the first main crescent plate 101 can form a first receiving area 17, which is configured to receive the second secondary crescent plate 203. Alternatively, the second crescent plate 2 further includes a second raised structure 204, which is disposed at one end of the second main crescent plate 201 opposite to the second secondary crescent plate 203. The second raised structure 204 and the second main crescent plate 201 can form a second receiving area 18, which is configured to receive the first secondary crescent plate 103. Alternatively, the first crescent plate 1 may further include a first raised structure 104, which is disposed at one end of the first main crescent plate 101 away from the first secondary crescent plate 103. The first raised structure 104 and the first main crescent plate 101 can form a first receiving area 17, which is configured to receive the second secondary crescent plate 203. Furthermore, the second crescent plate 2 may further include a second raised structure 204, which is disposed at one end of the second main crescent plate 201 away from the second secondary crescent plate 203. The second raised structure 204 and the second main crescent plate 201 can form a second receiving area 18, which is configured to receive the first secondary crescent plate 103.

[0104] Specifically, as shown in Figure 7, in this embodiment of the application, the first raised structure 104 and the first main crescent plate 101 form the first receiving area 17, and the second raised structure 204 and the second main crescent plate 201 form the second receiving area 18, so that the first secondary crescent plate 103 can be placed in the second receiving area 18, and the second secondary crescent plate 203 can be placed in the first receiving area 17, thereby effectively improving the stability of the first secondary crescent plate 103 and the second secondary crescent plate 203 and preventing the first secondary crescent plate 103 and the second secondary crescent plate 203 from falling off during use.

[0105] According to another embodiment of this application, a gear pump 31 is provided. The gear pump 31 includes a gear 9, a gear ring 10, and a gear pump filler 30 as described in the embodiments of this application. The gear 9 is internally engaged with the gear ring 10. One end of the gear pump filler 30 abuts against the gear 9. The other end of the gear pump filler 30 abuts against the gear ring 10.

[0106] Specifically, as shown in Figures 1 and 2, in this embodiment, one end of the gear pump filler 30 abuts against the tip circle of the gear 9, and the other end of the gear pump filler 30 abuts against the tip circle of the gear ring 10. This allows the gear pump filler 30 to be installed between the gear 9 and the gear ring 10 of the internal gear pump 31, thereby ensuring that the hydraulic oil in the internal gear pump 31 can be smoothly transferred from the first chamber 13 to the second chamber 14, or ensuring that the hydraulic oil in the internal gear pump 31 can be smoothly transferred from the second chamber 14 to the first chamber 13.

[0107] In one embodiment, the gear pump 31 further includes a first fluid chamber 11 and a second fluid chamber 12. The first fluid chamber 11 is disposed between the gear 9 and the gear pump filler 30. The second fluid chamber 12 is disposed between the gear ring 10 and the gear pump filler 30.

[0108] Specifically, as shown in Figures 1 and 2, after the first crescent plate 1 and the second crescent plate 2 are rotated and engaged in the embodiment of this application, the first main crescent plate 101 and the second main crescent plate 201 are located in the same arc segment on the side near the gear 9, and the first auxiliary crescent plate 103 and the second auxiliary crescent plate 203 are located in the same arc segment on the side near the gear ring 10.

[0109] Furthermore, after the first main crescent plate 101 abuts against the tip circle of the gear 9, the second main crescent plate 201 abuts against the tip circle of the gear 9, the first auxiliary crescent plate 103 abuts against the tip circle of the gear ring 10, and the second auxiliary crescent plate 203 abuts against the tip circle of the gear ring 10, the gear pump filler 30 can effectively divide the fluid space between the gear 9 and the gear ring 10 into a first fluid chamber 11 enclosed by the gear pump filler 30 and the gear 9 and a second fluid chamber 12 enclosed by the gear pump filler 30 and the gear ring 10.
