Description

Technical Field

[0001] This utility model relates to the field of power chassis and agricultural machinery technology, and in particular, to a general-purpose power chassis and agricultural machinery for hilly and mountainous areas. Background Technology

[0002] In modern agricultural production, the versatility and power adaptability of agricultural machinery directly affect operational efficiency and resource utilization. Currently, most agricultural machinery chassis on the market employ a single power output mode. For example, traditional chassis rely solely on the engine to directly drive the wheels and transmit power to the working device via mechanical transmission. This design has significant limitations: when the machinery is operating at low speed or idling, the engine maintains a high RPM for extended periods, resulting in excessive fuel consumption, significant energy wastage, and noise pollution, failing to meet the green and energy-saving development requirements of modern agriculture. Furthermore, traditional chassis lack energy storage and auxiliary drive mechanisms, making them unsuitable for new agricultural equipment requiring electric drive (such as electric sprayers and intelligent monitoring equipment), thus greatly reducing the chassis's versatility. Simultaneously, some existing hybrid chassis require the engine to connect the wheels and generator via multi-stage gear transmission, increasing the overall weight and risk of failure, and causing a decrease in power output stability due to transmission losses. In addition, agricultural machinery such as tractors usually need to tow a working mechanism (such as a rotary tiller). The power of this working mechanism needs to be input from the power take-off shaft of the chassis. If the engine is only used to generate electricity, then the drive of the wheels and the rotation of the power take-off shaft both need to be driven by electric motors, resulting in too many electric motors. In addition, the speed that the power take-off shaft needs to output is usually relatively stable, and it does not need to use electric motors to adjust the speed. Moreover, the power output required by the power take-off shaft is usually several times that of the wheel rotation. If the power take-off shaft is driven by electric motors, the power requirements of the electric motors are large, and the size and cost of the electric motors are high. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a universal dynamic chassis for hilly and mountainous terrain.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A general-purpose power chassis for hilly and mountainous terrain includes: a chassis body; wheels rotatably mounted on the chassis body; an engine mounted on the chassis body and connected to a rotating shaft; a generator mounted on the chassis body, the central shaft of the generator being connected to the rotating shaft; a battery mounted on the chassis body and connected to the generator to store the electrical energy generated by the generator; a motor mounted on the chassis body and connected to the wheels to drive the wheels to rotate; and a power output shaft connected to the rotating shaft to output mechanical power.

[0006] Furthermore, an output gear is mounted on the rotating shaft, and a first driven gear is mounted on the central shaft, with the output gear meshing with the first driven gear.

[0007] Furthermore, a second driven gear is mounted on the power output shaft, and the second driven gear meshes with the output gear.

[0008] Furthermore, the wheel body is provided with two sets of wheels spaced apart front and rear, and the wheels in the same set are spaced apart left and right. The wheel body has an axle at its center, and the axle is rotatably mounted on the chassis body along its own axis.

[0009] Furthermore, there are two motors, and the axles of the two wheels in the same group are connected by a differential assembly.

[0010] Furthermore, the chassis body includes a front chassis and a rear chassis; the front chassis and the rear chassis are hinged together, the engine is connected to a rotary output shaft, the rotary output shaft is rotatably mounted on the front chassis along its own axis, and the rotary shaft is rotatably mounted on the rear chassis; the rotary output shaft and the rotary shaft are connected by a drive shaft, and the two ends of the drive shaft are respectively connected to the rotary output shaft and the rotary shaft through universal joints.

[0011] Furthermore, the differential assembly includes a rotating sleeve and a planetary gear. The two ends of the rotating sleeve are respectively rotatably sleeved on the axles of the two wheel bodies in the same group. The planetary gear is rotatably mounted on the rotating sleeve along its own axis. The planetary gear can rotate around the axle with the rotating sleeve. The axle end is provided with bevel teeth. The planetary gear meshes with the bevel teeth on the axles of the two wheel bodies in the same group.

[0012] Furthermore, the output shafts of the two motors are respectively connected to the differential assemblies corresponding to the two sets of wheels.

[0014] This utility model also provides an agricultural machine, including a general-purpose power chassis for hilly and mountainous terrain.

[0015] This utility model has the following beneficial effects:

[0016] The engine drives a rotating shaft, which is connected to the generator's central shaft and power output shaft. Simultaneously, the motor is connected to the wheel drive, creating a dual output mode of mechanical and electrical power. The power output shaft is directly driven by the engine through the rotating shaft, providing a stable high-power output suitable for hilly and mountainous tractor trailer operations. This solves the problem of traditional hybrid chassis requiring a high-power motor to drive the power output shaft, which leads to increased cost and size. The generator obtains power from the engine via the rotating shaft, producing electricity that is stored in a battery. The battery then powers the motor to drive the wheels, meeting the chassis's driving needs and the power requirements of other attached equipment (electric sprayers, intelligent monitoring equipment), significantly improving the chassis's versatility. Furthermore, the motor control is precise, accurately driving the chassis movement. Compared to traditional single-power-output chassis, this chassis does not require the engine to maintain high speed during low-speed operation or idling. It can drive the motor through battery power, reducing the engine's ineffective running time, and lowering fuel consumption and noise pollution. At the same time, the generator and power output shaft share the engine's rotating shaft drive, simplifying the transmission mechanism, improving the stability of power transmission and the reliability of chassis operation, and reducing energy loss during power transmission, further improving energy utilization efficiency.

[0038] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a general-purpose power chassis for hilly and mountainous terrain, comprising a chassis body 100, wheels 200, an engine 300, a generator 400, a battery 500, a motor 600, and a power output shaft 700.

[0039] The wheel 200 is rotatably mounted on the chassis body 100.

[0040] The engine 300 is mounted on the chassis body 100 and is connected to the rotating shaft 310 for transmission.

[0041] The generator 400 is mounted on the chassis body 100. The central shaft 410 of the generator 400 is connected to the rotating shaft 310. The central shaft 410 is connected to the rotor inside the generator 400, and generates electricity by driving the rotor to rotate.

[0042] Battery 500 is connected to generator 400 to store the electrical energy generated by generator 400; battery 500 is installed on chassis body 100. The stored electrical energy in battery 500 powers motor 600, which in turn drives wheels 200, satisfying the chassis's need for flexible movement in complex mountainous terrain and powering new electric equipment such as electric sprayers and intelligent monitoring devices, significantly improving the chassis's versatility. Understandably, to control battery 500, chassis body 100 typically includes a power processor 800 to control the electrical output of battery 500.

[0043] The motor 600 is mounted on the chassis body 100 and is connected to the wheel body 200 to drive the wheel body 200 to rotate.

[0044] The power output shaft 700 is connected to the rotating shaft 310 to output mechanical power. The power output shaft 700 is rotatably mounted on the chassis body 100 and can be driven by the rotating shaft 310 to achieve rotational movement, thereby outputting power. Normally, the power output shaft 700 is axially fixed to the chassis body 100 so that the power output shaft 700 can only rotate and cannot move axially.

[0045] This utility model provides a universal power chassis for hilly and mountainous terrain. An engine 300 is driven by a rotating shaft 310, which is connected to the central shaft 410 of a generator 400 and the power output shaft 700. Simultaneously, a motor 600 is connected to the wheels 200, forming a dual output mode of mechanical and electrical power. The power output shaft 700 is directly driven by the engine 300 through the rotating shaft 310, enabling stable high-power output. This meets the needs of tractor-trailer operations in hilly and mountainous terrain, solving the problem of high cost and size increases associated with traditional hybrid chassis that rely on electric motors to drive the power output shaft. The generator 400 obtains power from the engine 300 through the rotating shaft 310 to generate electricity, which is stored in a battery 500. The battery 500 powers the motor 600 to drive the wheels 200, meeting the driving needs of the chassis 100 and the power requirements of other attached equipment (electric sprayers, intelligent monitoring equipment), significantly improving the chassis's versatility. Furthermore, the motor control is precise, accurately driving the chassis movement. Compared to traditional single-power-output chassis, this chassis does not require the engine 300 to maintain a high speed during low-speed operation or idling. Furthermore, when only moving without performing operations, the motor 600 can be driven by the battery 500, reducing the ineffective running time of the engine 300 and lowering fuel consumption and noise pollution. At the same time, the generator 400 and the power output shaft 700 share the rotation shaft 310 of the engine 300, simplifying the transmission mechanism, improving the stability of power transmission and the reliability of chassis operation, and reducing energy loss during power transmission, further improving energy utilization efficiency.

[0046] Reference Figure 1 In some embodiments of this invention, an output gear 311 is mounted on the rotating shaft 310, and a first driven gear 411 is mounted on the central shaft 410. The output gear 311 meshes with the first driven gear 411. By employing the gear meshing transmission between the output gear 311 and the first driven gear 411, efficient power transmission from the engine to the generator is achieved. The output gear 311 and the first driven gear 411 can be bevel gears or spur gears, which can be selected according to actual needs.

[0047] Reference Figure 1 In a further embodiment of this utility model, a second driven gear 710 is mounted on the power output shaft 700, and the second driven gear 710 meshes with the output gear 311. By meshing the second driven gear 710 of the power output shaft 700 with the output gear 311 of the rotating shaft 310, the output gear 311 of the rotating shaft 310 achieves dual drive of the central shaft 410 and the power output shaft 700. This eliminates the need for a separate transmission mechanism on the rotating shaft 310 for the power output shaft 700, simplifying the overall transmission structure of the chassis and reducing the number of transmission components.

[0048] Reference Figures 3 to 5 In a specific embodiment of this utility model, two sets of wheels 200 are arranged at intervals front and rear, and wheels 200 in the same set are arranged at intervals left and right. A wheel axle 210 is provided at the center of each wheel 200, and the wheel axle 210 is rotatably mounted on the chassis body 100 along its own axis. The wheel axle 210 can be axially fixed to the chassis body 100 through its own shoulder, limit nut, or other structures.

[0049] Reference Figure 1 and Figure 5 In a further embodiment of this utility model, two motors 600 are provided to drive two sets of wheels 200 to rotate respectively. The axles 210 of the two wheels 200 in the same set are connected by a differential assembly 900. The two motors 600 provide power to the front and rear sets of wheels 200 respectively, avoiding the problem of insufficient power caused by excessive load on a single motor. This is especially suitable for the high power requirements when climbing hills and overcoming obstacles. The addition of the differential assembly 900 can automatically adjust the speed difference between the left and right wheels 200 in the same set when the chassis is turning, reducing the sliding friction between the wheels 200 and the ground, reducing steering resistance, and preventing the tires from wearing out too quickly.

[0050] Reference Figure 4 In a further embodiment of this utility model, the chassis body 100 includes a front chassis 110 and a rear chassis 120; the front chassis 110 and the rear chassis 120 are hinged, with the hinge axis being a vertical axis, allowing the front chassis 110 and the rear chassis 120 to have relative left-right swing freedom. The engine 300 is connected to a rotary output shaft 320, which is rotatably mounted on the front chassis 110 along its own axis, and a rotary shaft 310 is rotatably mounted on the rear chassis 120 along its own axis; the rotary shaft 310 can be axially fixed to the chassis body 100 through its own shoulder, limit nut, or other structures. Specifically, a clutch can be provided between the engine 300 and the rotary output shaft 320 to realize power transmission and cut-off control. The rotary output shaft 320 and the rotary shaft 310 are connected by a transmission shaft 330, with both ends of the transmission shaft 330 connected to the rotary output shaft 320 and the rotary shaft 310 respectively through universal joints. The hinged connection between the front chassis 110 and the rear chassis 120 improves chassis flexibility, reduces the turning radius, and enhances off-road capability. The rotary output shaft 320 and rotary shaft 310 are connected via a drive shaft 330 and a universal joint, achieving stable power transmission and flexible adaptability. The universal joint and drive shaft 330 ensure stable power transmission from the rotary output shaft 320 of the engine 300 to the rotary shaft 310 of the rear chassis 120 when the angles of the front and rear chassis change, avoiding power interruption or component damage problems that occur with traditional rigid transmissions when the chassis deforms.

[0051] Reference Figure 1 and Figure 2In a further embodiment of this utility model, the differential assembly 900 includes a rotating sleeve 910 and planetary gears 920. The rotating sleeve 910 is rotatably fitted at both ends onto axles 210 on two wheel bodies 200 in the same group. The planetary gears 920 are rotatably mounted on the rotating sleeve 910 along their own axes. A gear shaft 930 is rotatably mounted on the rotating sleeve 910. Two planetary gears 920 are provided, both mounted on the gear shaft 930 so that they can rotate synchronously with the gear shaft 930. The gear shaft 930 can be axially fixed to the rotating sleeve 910 through its own shoulder, limiting nut, or other structures.

[0052] The planetary gear 920 rotates around the axle 210 with the rotating sleeve 910. The axle 210 has bevel teeth 211 at its end, and the planetary gear 920 simultaneously meshes with the bevel teeth 211 on the axles 210 of the two gear bodies 200 in the same group. Through the cooperation of the rotating sleeve 910, the planetary gear 920, and the bevel teeth 211, power distribution between the two gear bodies 200 in the same group is achieved. The planetary gear 920 can transmit power by revolving around the axle 210 with the rotating sleeve 910, and it can also adjust the speed difference of the gears by rotating on its own. Especially in hilly and mountainous terrain with curves and slopes, this structure can balance the rotational speed of the left and right gear bodies 200 in real time, ensuring stable chassis operation and reducing bumps in the working mechanism.

[0053] Reference Figure 1 and Figure 2 In a further embodiment of this invention, the output shafts of the two motors 600 are respectively connected to the differential assemblies 900 corresponding to the two sets of wheels 200. This achieves one-to-one power control of the motors, differentials, and a set of wheels, improving the chassis's power response speed and handling precision. Each motor 600 can independently adjust its output power according to the terrain requirements of its corresponding wheel 200.

[0054] Reference Figure 1 and Figure 2 In a further embodiment of this utility model, the rotating sleeve 910 is provided with an input gear 911, and the output shaft of the motor 600 is connected to a drive gear 610 that meshes with the input gear 911. The meshing of the input gear 911 with the drive gear 610 of the motor 600 achieves efficient power transmission from the motor to the differential assembly 900. The rigidity of the gear meshing transmission ensures stable power transmission from the motor 600 to the rotating sleeve 910. The gears have strong wear resistance and impact resistance, enabling them to withstand the load impact of mountain operations, reducing transmission component failures, and improving the overall reliability and service life of the chassis. The input gear 911 and the drive gear 610 can be matched bevel gears or spur gears.

[0055] Reference Figures 3 to 5This utility model also provides an agricultural machine, specifically a tractor, including a general-purpose power chassis for hilly and mountainous terrain. The integration of this general-purpose power chassis into agricultural machinery (such as a tractor) enables the agricultural machinery to adapt to and upgrade its performance in complex mountainous environments. The chassis's dual output modes of mechanical and electrical power can meet the power needs of different agricultural machines.

[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
