Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of controllers, and particularly relates to a motor controller and a vehicle. BACKGROUND

[0002] The inclined shaft motor is a kind of hydraulic piston motor with a certain working angle between the cylinder rotation center and the driving shaft rotation center. The inclined shaft motor is the most widely used power execution component in the fields of engineering machinery, agricultural machinery, industrial machinery, etc. The accurate and rapid control of the motor displacement is a key prerequisite for the efficient work of the entire hydraulic system. Specifically, the minimum current at which the motor controller starts to change the motor displacement, as the current increases, the electromagnetic thrust increases, and when it increases to the point where it can push the valve core to move, the control of the motor displacement begins. This minimum current value can be adjusted by changing the valve core spring pre-tightening force, which is called the control starting point.

[0003] At present, the commonly used inclined shaft motor controller includes an electromagnet, a controller valve core, a pre-tightening spring, a feedback spring, a starting point adjustment screw and a spring adjusting seat. Among them, the electromagnet provides different thrusts according to different control currents to push the controller valve core to move; the valve core is simultaneously subjected to the axial force from the pre-tightening spring and the axial force from the feedback spring; the starting point adjustment screw can change the position of the starting point spring seat to achieve different compression amounts of the pre-tightening spring and different forces; the actual displacement of the motor affects the compression amount of the feedback spring to achieve different feedback spring forces; different control current sizes can affect the force of the electromagnet; the changes of these three forces can achieve different positions and movement modes of the valve core, thereby realizing different motor displacement control modes.

[0004] However, the above motor controller is mainly liquid controlled, wherein the starting point spring seat and the starting point spring need to be installed on the motor rear cover and work cooperatively with the rear cover to realize the starting point adjustment function. This results in a complex starting control structure, a large size, and an impact on the motor height size; the starting point control structure needs to work cooperatively with the rear cover, and the disassembly and replacement operation is complex. Moreover, the cooperation gap between the existing controller valve core and the controller shell is small, sensitive to impurities, and prone to be stuck due to impurities in the hydraulic system, which affects the normal displacement adjustment of the motor. At the same time, the use scene of domestic hydraulic motors is complex, and the oil cleanliness is difficult to guarantee. SUMMARY

[0060] like Figures 1-5 As shown, according to an embodiment of the present invention, a motor controller is proposed. In terms of overall design, the motor controller includes a main body 1, a controller valve core 2, an electromagnet 3, a pre-tightening assembly 4, an adjusting rod 5 and a filter 6.

[0061] The main body 1 has a first accommodating cavity 11, the controller valve core 2 is accommodated in the first accommodating cavity 11, the electromagnet 3 is installed on the main body 1 and used for pushing the controller valve core 2 to move. The pre-tightening assembly 4 is arranged in the first accommodating cavity 11, the pre-tightening assembly 4 comprises a pre-tightening seat 41 and an elastic piece 42, one end of the elastic piece 42 abuts against the pre-tightening seat 41, and the other end of the elastic piece 42 abuts against the controller valve core 2. The adjusting rod 5 is installed on the main body 1, the adjusting rod 5 is arranged in connection with the pre-tightening seat 41, and the adjusting rod 5 is used for changing the position of the pre-tightening seat 41 in the first accommodating cavity 11, so as to adjust the compression amount of the elastic piece 42. The filter 6 is arranged on the main body 1, and the filter 6 is used for cleaning hydraulic oil flowing to the controller valve core 2.

[0062] The motor controller comprises the main body 1, the controller valve core 2, the electromagnet 3, the pre-tightening assembly 4, the adjusting rod 5 and the filter 6. By arranging the pre-tightening assembly 4 with the elastic piece 42 and the pre-tightening seat 41, the axial force of the controller valve core 2 is realized, the pushing force provided by the electromagnet 3 is matched, different positions and movement modes of the controller valve core 2 are realized, and different motor displacement control modes are realized. The position adjustment of the pre-tightening seat 41 is realized by arranging the pre-tightening assembly 4 and the adjusting rod 5 on the main body 1, so that the function of adjusting the control starting point is realized, the function of adjusting the control starting point is integrated on the motor controller, and the adjustment function with the rear cover system is no longer needed, and the starting control structure is optimized. Meanwhile, the arrangement of the filter 6 can effectively prevent impurities from entering the controller valve core 2, improve the anti-pollution capability of the controller, increase the maintenance period of the motor and reduce the risk of jamming of the controller valve core 2.

[0063] Specifically, the electromagnet 3 is installed on the main body 1, and the first accommodating cavity 11, the second accommodating cavity 12 and the third accommodating cavity 13 are arranged in the main body 1. Figure 1 As shown in the figure, the first accommodating cavity 11 is a columnar accommodating cavity, the controller valve core 2 and the pre-tightening assembly 4 are arranged in the first accommodating cavity 11, the controller valve core 2 is arranged in connection with the electromagnet 3, when the motor controller works, the electromagnet 3 receives current, and then the electromagnet 3 provides different pushing forces according to different control currents, so that the controller valve core 2 moves in the first accommodating cavity 11.

[0064] Still as shown in the figure, Figure 1 and Figure 3As shown, the pre-tightening assembly 4 comprises a pre-tightening seat 41 and an elastic member 42, in this embodiment, the elastic member 42 is provided as a pre-tightening spring, the pre-tightening spring is sleeved on the controller spool 2, the pre-tightening seat 41 is sleeved on the outside of the pre-tightening spring, one end of the pre-tightening seat 41 is provided with an action plate 411, one end of the pre-tightening spring abuts against the action plate 411, the other end of the pre-tightening spring abuts against the controller spool 2, when the pre-tightening seat 41 is fixed in the first accommodating cavity 11, the pre-tightening spring is in a compressed state, and has an action force for moving the controller spool 2 away from the pre-tightening spring.

[0065] In this embodiment, the adjusting rod 5 is installed in the third accommodating cavity 13 of the main body 1, the third accommodating cavity 13 is a columnar accommodating cavity as a whole, and is provided in communication with the first accommodating cavity 11, the axis of the third accommodating cavity 13 is provided perpendicularly to the axis of the first accommodating cavity 11, so that the axial direction of the adjusting rod 5 can be perpendicular to the axial direction of the controller spool 2. At the same time, the adjusting hole 412 is formed on the peripheral surface of the pre-tightening seat 41, the adjusting rod 5 can change the position of the pre-tightening seat 41 in the first accommodating cavity 11 by acting on the inner wall of the adjusting hole 412. Specifically, the adjusting rod 5 is installed in the third accommodating cavity 13 of the main body 1, and the axial direction of the adjusting rod 5 is provided perpendicularly to the axial direction of the controller spool 2. In combination with the adjusting hole 412 formed on the peripheral surface of the pre-tightening seat 41, the adjusting rod 5 can change the position of the pre-tightening seat 41 in the first accommodating cavity 11. Figure 2 As shown, the eccentric column 51 is configured on the end face of the first end of the adjusting rod 5, and the eccentric column 51 can be accommodated in the adjusting hole 412, when the adjusting rod 5 rotates around its own axis, the eccentric column 51 will make a revolution motion along the axis of the adjusting rod 5 with the rotation of the adjusting rod 5, and at this time, the eccentric column 51 will always act on the inner wall of the adjusting hole 412, and drive the pre-tightening seat 41 to make a reciprocating motion along the axial direction of the controller spool 2, thereby achieving the effect of changing the compression amount of the pre-tightening spring.

[0066] Here, it should be noted that the structure of the adjusting rod 5 can also adopt other structural forms, for example, the cross section of the above-mentioned eccentric column 51 can also be oval, semicircular, etc., so that the adjusting rod 5 can have different height positions at different fixed angles. Of course, in addition thereto, the connection mode of the adjusting rod 5 and the pre-tightening seat 41 can also adopt other meshing modes, so that the adjusting rod 5 can change the position of the pre-tightening seat 41 in the first accommodating cavity 11, such as using a slope pushing structure, etc.

[0067] In some embodiments of the present application, the motor controller further comprises a mounting plate 7. In this embodiment, the mounting plate 7 is detachably mounted on the main body 1, and the adjusting rod 5 is rotatably mounted on the mounting plate 7. In this way, the adjusting rod 5 can be mounted on the mounting plate 7 in advance, and then the mounting plate 7 is assembled on the main body 1 to complete the installation of the adjusting rod 5. At the same time, the mounting plate 7 can also prevent the eccentric column 51 from being separated from the adjusting hole 412, thereby limiting the movement of the eccentric column 51 along its axial direction, which helps to simplify the assembly of the adjusting rod 5, improve the assembly efficiency of the motor controller, and facilitate the replacement of the adjusting plate and improve the maintenance efficiency of the motor controller.

[0068] In some embodiments of the present application, the motor controller further comprises a locking assembly 8 mounted on one end of the adjusting rod 5. The locking assembly 8 is used to mount the adjusting rod 5 on the mounting plate 7 and make the adjusting rod 5 enter a non-rotatable working state. The locking assembly 8 is used for the installation of the adjusting member and the rotation limitation of the adjusting member, so as to prevent the adjusting member from rotating during the operation of the motor controller and affecting the position of the pre-tightening seat 41 in the first accommodating cavity 11, thereby improving the safety and accuracy of the motor controller.

[0069] Specifically, as shown in Figure 1 and Figure 2 , the adjusting rod 5 has an action surface 52 abutting against the mounting plate 7, and a threaded column 53 penetrating through the mounting plate 7 is arranged at the second end of the adjusting rod 5. The locking assembly 8 comprises a threaded member 81 mounted on the threaded column 53 and a gasket 82 located between the threaded member 81 and the mounting plate 7. The threaded member 81 and the action surface 52 are located on the two sides of the mounting plate 7, respectively. In this embodiment, the threaded member 81 is a nut. When the nut is mounted on the threaded column 53, the nut can cooperate with the action surface 52 of the adjusting rod 5 to prevent the adjusting rod 5 from being separated from the mounting plate 7, thereby achieving the installation of the adjusting rod 5 on the mounting plate 7. At the same time, when the nut is tightened, the nut and the action surface 52 jointly act to limit the self-rotation of the adjusting rod 5. When the self-rotation of the adjusting rod 5 is needed, the nut needs to be loosened and the adjusting rod 5 needs to be rotated. When the adjusting rod 5 needs to be fixed, the position of the adjusting rod 5 needs to be kept unchanged and the nut needs to be tightened. In addition, the gasket 82 can protect the nut and the mounting plate 7, thereby improving the safety of the motor controller.

[0070] It should be noted that the above-mentioned locking assembly 8 can also be structured to rotatably mount the adjusting member on the mounting plate 7 and limit the installation of the adjusting member.

[0071] In addition, the mounting of the adjusting rod 5 in the third accommodating cavity 13 can also adopt other structures to ensure that the eccentric column 51 cannot be separated from the adjusting hole 412 and can complete the rotation of the adjusting rod 5 and the fixation after the rotation.

[0072] In some embodiments of the present application, the main body 1 has a second accommodating cavity 12, the second accommodating cavity 12 is provided with an oil channel input port 123 communicating with the outside and an oil channel output port 124 communicating with the controller spool 2, and a filter 6 is arranged between the oil channel input port 123 and the oil channel output port 124. Figure 4 and Figure 5 As shown in the drawings, in the present embodiment, the second accommodating cavity 12 is a cylindrical accommodating cavity, and the axial direction of the second accommodating cavity 12 is perpendicular to the axial direction of the first accommodating cavity 11. In this way, the filter 6 can be mounted, and the interference with the hydraulic oil delivery can be reduced. By arranging the second accommodating cavity 12 and the filter 6, the hydraulic oil flowing to the controller spool 2 can pass through the filter 6 to remove some impurities in the hydraulic oil, so that the impurities cannot flow to the spool, thereby achieving the protection function of the spool, increasing the maintenance period of the motor, and reducing the risk of spool jamming.

[0073] Specifically, the filter 6 includes a filter body and a gap filter element. The filter body is provided with a protrusion abutting against the inner wall of the second accommodating cavity 12 on the peripheral surface of the filter body, and the first end of the filter body is provided with a first channel 63. The gap filter element is sleeved on the peripheral surface of the filter body and abuts against the inner wall of the second accommodating cavity 12. The oil channel input port 123, the gap filter element, the first channel 63, and the oil channel output port 124 are sequentially communicated. In the present embodiment, since the second accommodating cavity 12 is a cylindrical accommodating cavity, and the axial direction of the second accommodating cavity 12 is perpendicular to the axial direction of the first accommodating cavity 11, the filter body of the filter 6 is generally cylindrical, and the axial direction of the filter body is perpendicular to the axial direction of the controller spool 2. The protrusion formed on the peripheral surface of the filter body abuts against the inner wall of the second accommodating cavity 12, which can ensure that the filter body is fixedly mounted in the second accommodating cavity 12 and avoid shaking due to the impact of the hydraulic oil.

[0074] In some embodiments of the present application, the number of protrusions is two, and the second accommodating cavity 12 is divided into a filtering cavity 121 and a delivery cavity 122.

The second oil channel input port and the outlet of the second channel 64 are both arranged on the input side of the gap filter element.

[0075] As shown in the drawings, in the present embodiment, the second accommodating cavity 12 is a cylindrical accommodating cavity, and the axial direction of the second accommodating cavity 12 is perpendicular to the axial direction of the first accommodating cavity 11. In this way, the filter 6 can be mounted, and the interference with the hydraulic oil delivery can be reduced. By arranging the second accommodating cavity 12 and the filter 6, the hydraulic oil flowing to the controller spool 2 can pass through the filter 6 to remove some impurities in the hydraulic oil, so that the impurities cannot flow to the spool, thereby achieving the protection function of the spool, increasing the maintenance period of the motor, and reducing the risk of spool jamming. Figure 6 and Figure 7As shown, the motor 10 generally has two oil channels, for ease of description, referred to as a first oil channel 101 and a second oil channel 102, the hydraulic oil in the first oil channel 101 and the second oil channel 102 will enter the controller spool 2 after passing through the one-way valve 103, and be controlled by the on-off control of the controller spool 2, and then flow to the control plunger cavity 104, the hydraulic oil in the control plunger cavity 104 will push the control plunger 105 to move, thereby realizing the variable displacement process of the motor. The filter 6 in the embodiment is installed between the one-way valve and the controller spool 2, and at this time, the hydraulic oil output from the one-way valve will enter the controller spool 2 after being filtered by the filter 6. In order to improve the applicability of the controller motor, two oil channel input ports 123 are provided in the second accommodating cavity 12, for ease of description, referred to as a first oil channel input port and a second oil channel input port, to ensure that the hydraulic oil in the above two oil channels will flow to the gap filter element.

[0076] Specifically, two protrusions are constructed on the filter body, for ease of description, referred to as a first protrusion 61 and a second protrusion 62, wherein the first protrusion 61 is arranged close to the first end of the filter body, and the second protrusion 62 is arranged close to the middle part of the filter body, a gap filter element is arranged between the first protrusion 61 and the second protrusion 62, and a filter cavity 121 is formed in cooperation with the filter body and the inner wall of the second accommodating cavity 12, and a delivery cavity 122 is formed on the other side of the second protrusion 62, and the filter cavity 121 and the delivery cavity 122 are communicated through the second channel 64. The first oil channel input port is provided in the delivery cavity 122, and the second oil channel input port is provided in the filter cavity 121 and located between the second protrusion 62 and the gap filter element.

[0077] In the embodiment, a first channel 63 is constructed at the first end of the filter body. The liquid inlet of the first channel 63 is provided on the peripheral surface of the filter body, the liquid outlet of the first channel 63 is directly communicated with the oil channel output port 124, and the liquid inlet and the liquid outlet of the first channel 63 are arranged on the two sides of the first protrusion 61, respectively. Correspondingly, a second channel 64 is constructed at the second end of the filter body. The liquid inlet and the liquid outlet of the second channel 64 are both provided on the peripheral surface of the filter body and arranged on the two sides of the second protrusion 62, respectively. The hydraulic oil output by the first oil channel input port will enter the filter cavity 121 through the second channel 64, and be integrated with the hydraulic oil output by the second oil channel input port, and then flow to the gap filter element together, and after passing through the gap filter element, directly enter the oil channel output port 124 through the first channel 63.

[0078] In some embodiments of the present application, the gap filter core comprises a first gap filter core 91 and a second gap filter core 92. The first gap filter core 91 is arranged close to the oil passage inlet 123. The second gap filter core 92 is arranged close to the first passage 63, and the gap value of the second gap filter core 92 is smaller than that of the first gap filter core 91. Specifically, the first gap filter core 91 and the second gap filter core 92 are arranged in a spaced manner. In the present embodiment, the first gap filter core 91 is arranged close to the second protrusion 62, and the second gap filter core 92 is arranged close to the first protrusion 61. The first gap filter core 91 and the second gap filter core 92 are arranged with different gap values by size control, and the gap value of the second gap filter core 92 is smaller than that of the first gap filter core 91. During the advance of the hydraulic oil, the impurities in the hydraulic oil with a size larger than the gap value cannot pass through, thereby realizing the filtering function.
