Description

Technical Field

[0001] The present invention relates to the technical field of drive systems, and particularly to an electromechanical-hydraulic combined power system for chassis drive and control. Background Art

[0002] Currently, the traveling mode of agricultural machinery equipment usually adopts a crawler chassis. The traditional structure is mostly pure mechanical, generally using an internal combustion engine (engine) as the power source, and then realizing power transmission and steering control through the combination of mechanisms such as gears, belts, chains, drive shafts, and gearboxes. Such a chassis has reliable transmission and is easy to manufacture, but its disadvantages have always been prominent. For example, problems such as excessive structural fixation, large weight and high power consumption of components, difficulty in realizing stepless speed regulation, and complex manual control are difficult to meet the requirements of contemporary agricultural machinery for intelligence and automation. Therefore, the pure mechanical chassis is gradually fading out of the market.

[0003] Taking pure electric drive as the research and development direction of agricultural machinery chassis, although its easy-to-control characteristics have achieved remarkable results in the short term, when carrying out agricultural production operations in actual complex environments, problems such as water ingress and short circuit, large-load circuit board burning, component fracture during vibration, and motor and control system failures often occur. Therefore, there are still many problems to be explored one by one in the application of pure electric drive chassis in agricultural machinery equipment, and it cannot be effectively applied in hilly and mountainous environments.

[0004] For hydraulic chassis, it is more applicable in agricultural machinery equipment and is relatively common in the market. In recent years, the full-hydraulic chassis drive scheme has been widely applied in plant protection machinery and harvesting machinery. However, there are internal linear vibrations, oil loss, and structural errors during the application process. Since high requirements are generally imposed on working stability, sensitivity, and controllability, its application in special agricultural machinery equipment and intelligent agricultural robots is still not widespread. To sum up, in order to meet the development needs of agricultural machinery equipment, it is necessary to combine automation, intelligence, and informatization technologies, and specifically design an electromechanical-hydraulic integrated agricultural machinery chassis, which is the key task for the development of mountain agricultural machinery equipment, and is also the key technology to be solved for fast driving and precise control, which is of great significance for the development of agricultural machinery equipment and agricultural robots in hilly and mountainous areas.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0028] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. 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 an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0029] See Figure 1 , a preferred embodiment of the present invention provides an electro-mechanical-hydraulic combined power system for chassis drive and control, including a chassis 1, a hydraulic system 2, a transmission system 3, an electromagnetic clutch 4, an execution operation component 5, a power source 6, and a link control mechanism 7; the hydraulic system 2 is connected to the chassis 1 for driving the chassis 1; the transmission system 3 includes a driving pulley 31, a constantly rotating pulley 32, a clutch pulley 33, a pump driving pulley 34, and a driven pulley 35; the pump driving pulley 34 is connected to the hydraulic system 2; the driving pulley 31 is connected to the pump driving pulley 34 through a transmission belt; the constantly rotating pulley 32 is connected to the driving pulley 31 through a transmission belt; the clutch pulley 33 is connected to the driven pulley 35 through a transmission belt; one end of the electromagnetic clutch 4 is connected to the constantly rotating pulley 32, and the other end is connected to the clutch pulley 33; the execution operation component 5 is connected to the driven pulley 35; the power source 6 is connected to the driving pulley 31 for driving the hydraulic system 2 and the execution operation component 5; the link control mechanism 7 is connected to the hydraulic system 2 for controlling the flow direction and flow rate of the hydraulic system 2.

[0030] It should be noted that the driving pulley 31 is a double-layer pulley.

[0031] In the using process of the above electro-mechanical-hydraulic combined power system for chassis drive and control, the power source 6 drives the driving pulley 31 to rotate, the driving pulley 31 drives the pump driving pulley 34 and the constantly rotating pulley 32 to rotate respectively, the pump driving pulley 34 drives the hydraulic system 2, and the hydraulic system 2 drives the chassis 1 to travel; and when it is necessary for the execution operation component 5 to work, only need to control the electromagnetic clutch 4 to be energized and attracted. At this time, the clutch pulley 33 rotates synchronously with the constantly rotating pulley 32, and then drives the driven pulley 35 to drive the execution operation component 5 to work. When stopping working, only need to cut off the power supply of the electromagnetic clutch 4. The link control mechanism 7 controls the traveling speed and direction of the chassis 1 by controlling the flow direction and flow rate of the hydraulic system 2.

[0032] See Figure 2, in some preferred embodiments of the present invention, the power source 6 is installed at the rearmost part of the chassis 1, the electromagnetic clutch 4 is located in front of the power source 6, the hydraulic system 2 is located in front of the electromagnetic clutch 4, the transmission system 3 is installed on the right side of the chassis 1, the link control device is located in front of the hydraulic system, and the working component 5 is located at the foremost part of the chassis 1. In this way, the whole can be made more compact, which not only meets the usage requirements but also does not increase the overall occupied volume of the system.

[0033] In some preferred embodiments of the present invention, the power source 6 is an engine.

[0034] In some preferred embodiments of the present invention, the chassis 1 includes a frame body, a crawler 12, a driving wheel 11 and auxiliary wheels. The driving wheel 11 and the auxiliary wheels are respectively arranged on the frame body, and the crawler 12 connects the driving wheel 11 and the auxiliary wheels; the driving wheel 11 is connected to the hydraulic system 2. In this way, the hydraulic motor 22 drives the driving wheel 11 to rotate, and the driving wheel 11 drives the auxiliary wheels through the crawler 12.

[0035] In some preferred embodiments of the present invention, the hydraulic system 2 includes a hydraulic pump 21, a hydraulic motor 22 and a hydraulic oil tank 23; the hydraulic pump 21 is connected to the pump driving pulley 34, the hydraulic motor 22 is connected to the hydraulic pump 21; the hydraulic motor 22 is connected to the chassis 1; the hydraulic oil tank 23 is connected to the hydraulic pump 21. Specifically, the pump driving pulley 34 drives the hydraulic pump 21, the hydraulic pump 21 drives the hydraulic motor 22, and the hydraulic motor 22 drives the driving wheel 11.

[0036] In some preferred embodiments of the present invention, the hydraulic system 2 further includes a heat dissipation and cooling element 24, and the heat dissipation and cooling element 24 is connected to the hydraulic pump 21.

[0037] See Figures 3 to 5 , in some preferred embodiments of the present invention, the hydraulic system 2 includes a flat shaft 25 and a hydraulic pump 21. An inclined disk main shaft is arranged inside the hydraulic pump 21, and the flat shaft 25 is connected to the inclined disk main shaft of the hydraulic pump 21; the link control mechanism 7 includes a servo motor 71, a rotating rod 72, a rotating bar 73 and a linkage handle 74. The servo motor 71 is arranged in the hydraulic system 2. One end of the rotating rod 72 is connected to the output shaft of the servo motor 71, the other end of the rotating rod 72 is hinged to one end of the rotating bar 73, the other end of the rotating bar 73 is hinged to one end of the linkage handle 74, and the other end of the linkage handle 74 is connected to the flat shaft 25.

[0038] It should be noted that the hydraulic pump 21 is an inclined disk type variable plunger series pump. The rotating bar 73 includes a stud, an inner rotating bar and an outer rotating bar. Both the inner rotating bar and the outer rotating bar are rotationally connected to the stud and can adjust the distance between the two hinge points at both ends by rotation; the distance adjustment method is not limited to the stud and can also be realized by other methods such as slider locking.

[0039] In some preferred embodiments of the present invention, the connecting rod control mechanism 7 further includes clamping arms 75, a tension spring 76, a contact bearing 77, and an eccentric sleeve 78. There are two clamping arms 75 symmetrically arranged up and down. One end of the two clamping arms 75 is arranged on the hydraulic pump 21, and the other ends of the two clamping arms 75 are respectively sleeved on both ends of the tension spring 76; the linkage handle 74 extends with a crank on the side of the tension spring 76, and the crank is provided with a bearing, and the inner surfaces of the two clamping arms 75 abut against the bearing; the eccentric sleeve 78 is rotatably installed on the hydraulic pump 21 with the eccentric part as the center, and the inner surfaces of the outermost ends of the two clamping arms 75 abut against the eccentric sleeve 78. When the eccentric sleeve 78 rotates, the two clamping arms 75 will no longer be in an up-and-down symmetrical form, and the position of the bisector of the two clamping arms 75 will be changed according to the rotation direction and rotation angle of the eccentric sleeve 78.

[0040] Specifically, when the chassis 1 needs to perform a walking action, the overall connecting rod control device can be driven and rotated by the servo motor 71, thereby driving the linkage of the connecting rod and the rotating rod 73, driving the flat shaft 25 to rotate around the center O1, and then realizing the control of the flow direction and flow rate of the hydraulic oil output by the hydraulic pump 21 to the hydraulic motor 22. Its "zero position line" is the theoretical static position and also the parking position. At this time, the hydraulic oil volume is zero. When the "zero position line" rotates counterclockwise or clockwise, the forward or backward movement of the crawler 12 chassis 1 is realized. When the rotation angle of the "zero position line" changes, the speed control of the vehicle speed is realized. When the actual angle of the "zero position line" is not 0 degrees due to oil volume error or mechanical error, the length of the inner rotating rod 73 and the outer rotating rod 73 can be adjusted to re-correct the "zero position line"; the cooperation of the upper and lower clamping arms 75 and the tension spring 76 can clamp the bearing at the end of the linkage handle 74, playing a role of assisting and stabilizing in the reset process of returning to the "zero position line", and can avoid the vibration during the rotation process and the up-and-down jitter phenomenon at the "zero position line".

[0041] It should be noted that the flat shaft 25 is coaxially and fixedly installed with the internal swash plate main shaft of the hydraulic pump 21. Its main function is to control the position of the swash plate angle inside the hydraulic pump 21, and then control the movement direction and oil volume of the hydraulic oil. For the convenience of angle control and installation, it is generally designed as a non-circular shaft with a flat and square structure, and the angle control is realized through the sleeve fit. At the same time, the servo motor 71 and the engine are both connected to an external control mechanism. A battery 8 is also provided on the chassis 1, and the servo motor 71 is connected to the battery 8. At the same time, there are two hydraulic systems 2, and they are arranged in series, respectively corresponding to the drive wheels 11 on both sides of the chassis 1. And the swash plate main shaft is a conventional setting in the existing hydraulic pump, and will not be elaborated here.

[0042] See Figure 6, in some preferred embodiments of the present invention, the servo motor 71 is provided with an angle sensor 711 and an end cover 712. The angle sensor 711 includes a rotor 7112 and a stator 7111. The rotor 7112 is connected to the output shaft of the servo motor 71. The end cover 712 is sleeved on the rotor 7112 and fixed to the servo motor 71. The stator 7111 is arranged on the end cover 712 and is arranged corresponding to the rotor 7112.

[0043] Specifically, the angle sensor 711 is composed of a stator 7111 and a rotor 7112. The rotor 7112 is coaxially and fixedly installed with the drive shaft of the reduction motor and can rotate synchronously. The end face seal cover is buckled and fixedly installed at the rear of the reduction motor. The stator 7111 is fixedly installed outside the end face seal cover through the hole positions.

[0044] In some preferred embodiments of the present invention, the operation component 5 is at least one rotary component such as weeding, rotary tillage, stubble cleaning, and crushing.

[0045] In summary, the preferred embodiments of the present invention provide an electro-mechanical-hydraulic combined power system for chassis drive and control. Compared with the prior art:

[0046] The electro-mechanical-hydraulic combined power system for chassis drive and control of the present invention drives the hydraulic pump 21 through the engine, integrates the angle sensor 711 into the motor, and is arranged on both sides of the series pump to independently drive the combined link mechanism, respectively control the rotation angles of the left and right flat shafts 25, and can real-time feedback the angle values through the angle sensor 711, and then control the size and direction of the swash plate inclination angle in the pump to adjust the flow direction and flow size of the left and right hydraulic motors 22, so as to realize the control of the rotation direction and rotation speed of the drive wheels 11 on both sides of the crawler 12.

[0047] On the other hand, due to various reasons such as poor sealing, impurities in the oil, too large pump clearance, or oil pressure error during the working process of the swash plate piston pump, the oil discharge amount when the swash plate is in the "middle position" is often not zero, that is, when the chassis 1 is in the theoretical static state, the situations of "creeping" or "deflection" often occur. Therefore, the present invention also sets an adjusting device in the above combined link mechanism, uses the screw rotation adjustment to change the length of the link mechanism, and indirectly finely adjusts the rotation angle of the flat shaft 25, and can realize the rapid and accurate correction of the "swash plate middle position".

[0048] It meets the operation requirements of large power and flexible control in complex terrain environments. At the same time, it solves the problems of large traditional hydraulic control error and difficult correction of middle position deviation, and is more suitable for agricultural production links in hilly and mountainous areas.

[0049] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
