Description

Technical Field

[0001] The present invention relates to the technical field of agricultural tractors, and particularly to a new energy hybrid agricultural tractor. Background Art

[0002] New energy hybrid agricultural tractors stem from the energy and environmental challenges of traditional agricultural machinery, as well as the significant advantages of hybrid technology in energy conservation, emission reduction, improving operation performance, and intelligence. With the continuous progress of technology and the increasing market demand, hybrid tractors are expected to be more widely used in the future, promoting the development of agricultural machinery towards green and intelligent directions.

[0003] Hybrid tractors perform well in large-area operations such as plowing, sowing, fertilizing, and harvesting, capable of providing strong power and long-lasting endurance. Compared with traditional diesel tractors, hybrid tractors significantly reduce fuel consumption by using electricity, reducing operating costs.

[0004] The existing technologies have the following deficiencies: 1. Traditional agricultural tractors use mechanical steering, and the power assistance of mechanical steering is relatively fixed and cannot be automatically adjusted according to vehicle speed and working conditions. Especially during low-speed operations, the steering becomes heavier, and the driver needs to apply a greater force to operate the steering wheel, increasing the labor intensity. 2. Series hybrid tractors are only used to drive the generator to generate electricity, and the motor drives the gears. The transmission efficiency is low, the energy conversion process is complex, and there are significant energy losses. During high-load operations, since the engine cannot directly drive the wheels, the fuel efficiency is reduced, and the structure is complex with high manufacturing costs, resulting in a high overall machine price and greater purchase pressure for users.

[0017] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0018] As Figures 1 - 8 shown, a new energy hybrid agricultural tractor includes a vehicle body 2, an operating room 1 is fixedly installed at the upper end of the vehicle body 2, a front hood 3 is fixedly installed at the front end of the operating room 1, a battery compartment 6 is fixedly installed inside the vehicle body 2 at the lower end of the front hood 3, a steering platform 213 is fixedly installed at the front end of the vehicle body 2, an electric auxiliary steering mechanism is fixedly installed at the front end of the steering platform 213, a rotating shaft 107 is rotatably installed at the rear end of the vehicle body 2, a bottom seal seat 106 is fixedly installed at the middle position inside the vehicle body 2 on the rotating shaft 107, a rear wheel drive mechanism is arranged inside the bottom seal seat 106, and the battery compartment 6 is respectively communicated with the rear wheel drive mechanism and the electric auxiliary steering mechanism through a wire splitting control mechanism; The rear wheel drive mechanism includes a drive motor 101 fixedly installed at the right rear end of the bottom seal seat 106, and an engine 108 is fixedly installed at the left front end of the bottom seal seat 106.

[0019] As Figure 4 、 Figure 7As shown in the figure, the wire splitting mechanism includes several storage batteries 7 fixedly installed inside the battery compartment 6. An inverter 8 is fixedly installed at the rear end of the battery compartment 6. A steering circuit 10 is fixedly installed at the bottom of the battery compartment 6. The steering circuit 10 is connected to the electric power-assisted steering mechanism. An auxiliary drive circuit 11 is fixedly installed at the rear end of the inverter 8. The auxiliary drive circuit 11 is connected to the drive motor 101. During the vehicle driving process, the inverter 8 converts the direct current inside the storage battery 7 into alternating current, driving the drive motor 101 to start working, enabling the vehicle to operate normally. During the braking or deceleration process, the drive motor 101 switches to the generator mode, and the inverter 8 converts the generated alternating current into direct current and stores it in the storage battery 7.

[0020] Steering wheels 4 are rotatably installed at both ends of the electric power-assisted steering mechanism, and drive rear wheels 5 are rotatably installed at both ends of the rear-wheel drive mechanism. Both the electric power-assisted steering mechanism and the rear-wheel drive mechanism are controlled by the wire splitting mechanism. By operating the control room 1 to control the storage battery 7 to output and drive the steering motor 201, the auxiliary steering can be realized, enabling the agricultural tractor to achieve smoother steering on muddy ground.

[0021] As Figure 5 , Figure 6 shown in the figure, the rear-wheel drive mechanism includes an electric drive gear 102 fixedly installed at the drive end of the drive motor 101. A coupler cover 9 is fixedly installed at the upper end to achieve the equipment sealing work. Inside the bottom seal seat 106, a transmission gear 103 is meshingly installed on one side of the electric drive gear 102. A power transmission rod 113 is meshingly installed on one side of the transmission gear 103. An oil drive gear 104 meshing with the transmission gear 103 is fixedly installed at the outer end of the power transmission rod 113. A shaft gear 105 meshing with the oil drive gear 104 is fixedly installed on the outer surface of the shaft 107. The power transmission rod 113 is fixedly installed at the output end of the engine 108. In the parallel drive mode of the present invention, the engine 108 and the drive motor 101 are allowed to work independently or cooperatively, so as to provide efficient power output and energy utilization.

[0022] A transmission cam 112 is fixedly installed on the outer side of the power transmission rod 113, a fixed seat 109 is fixedly installed at the front end of the engine 108, a driving cam 110 is fixedly installed at the output end of the engine 108, a reduction cam 111 is rotatably installed on the left side of the driving cam 110 with the fixed seat 109, and both the transmission cam 112 and the reduction cam 111 are engaged with the driving cam 110. The engine 108 provides traditional fuel power and is usually used in high-load working conditions, such as when a tractor is cultivating or driving on muddy ground. The drive motor 101 can drive the tractor as an electric motor or can also generate electricity for the battery 7 as a generator. Among them, the inverter 8 converts the direct current in the battery 7 into the alternating current required by the drive motor 101, and at the same time converts the alternating current generated by the motor into direct current and stores it in the battery during braking.

[0023] As Figure 8 shown, the electric-assisted steering mechanism includes a steering motor 201 vertically and fixedly installed at the middle position of the steering platform 213. A steering gear disc 202 is fixedly installed at the output end of the steering motor 201. Transverse guide rods 203 are rotatably installed at both ends of the steering platform 213 with respect to the steering motor 201. Transmission gear discs 204 are fixedly installed at both ends of the transverse guide rods 203, and the transmission gear discs 204 are engaged with the steering gear disc 202. Fixed long plates 212 are fixedly installed on both sides of the outer surface of the steering platform 213.

[0024] Three equally spaced rotating seats 207 are fixedly installed on the outer surface of each fixed long plate 212. A long rod 206 is rotatably installed between the rotating seats 207. A follower gear disc 205 is fixedly installed at one end of the long rod 206 close to the steering platform 213. A telescopic rod 208 is rotatably installed at the other end of the follower gear disc 205. According to the driving requirements, the battery 7 is controlled to drive the steering motor 201 to assist in steering.

[0025] Support plates 210 are rotatably installed on the outer sides of each fixed long plate 212. Connecting turntables 209 are fixedly installed on the opposite outer surfaces of each support plate 210. Steering shafts 211 are fixedly installed on the opposite outer surfaces of the two connecting turntables 209. The telescopic end of the telescopic rod 208 is rotatably installed at the upper end of the connecting turntable 209. When the steering motor 201 works, the upper steering gear disc 202 starts to rotate, thereby driving the engaged transmission gear discs 204, causing the long rod 206 rotatably installed on the outer side of the fixed long plate 212 to rotate. One end of the long rod 206 is rotatably installed with a telescopic rod 208. The length of the telescopic rod 208 is adjusted by adjusting the long rod 206, thereby changing the angle of the support plate 210 at the front end of the fixed long plate 212. The steering shaft 211 fixedly installed on the support plate 210 rotates accordingly to achieve assisted steering.

[0026] Working principle: This new energy hybrid agricultural tractor adopts a parallel drive architecture and can be switched to the drive motor 101 drive mode, the engine 108 drive mode, and the hybrid drive mode of the drive motor 101 and the engine 108 according to different working conditions and driving requirements. When in the drive motor 101 drive mode, the engine 108 stops running, and the vehicle is driven solely by the drive motor 101. The storage battery 7 inside the battery compartment 6 supplies electrical energy to the drive motor 101. The drive motor 101 drives the electric drive gear 102, and the power is sequentially transmitted to the axle gear 105 through the transmission gear 103, thus realizing pure electric drive, which is suitable for low-speed driving and agricultural operations with relatively low intensity.

[0027] In the engine 108 drive mode, the engine 108 starts to directly drive the vehicle, and the power transmission rod 113 rotates alone. At this time, the oil drive gear 104 on the outer surface drives the axle gear 105 on one side to rotate, and the electric drive gear 102 on the other side starts to generate electricity driven by the transmission gear 103. At this time, the drive motor 101 does not participate in power output, but can be used as a generator to charge the storage battery 7, which is suitable for medium-load working conditions. At this time, the engine 108 works in the high-efficiency area, and the fuel economy is good.

[0028] In the hybrid drive mode of the engine 108 and the drive motor 101, the engine 108 and the drive motor 101 work simultaneously, and the electric drive gear 102 and the power transmission rod 113 rotate simultaneously, thus reducing the working pressure of a single drive component. It is suitable for high-load operations such as plowing and climbing slopes. The hybrid drive mode provides stronger power output, and the assistance of the drive motor 101 can improve fuel economy and reduce emissions.

[0029] When the driver is ready to start the new energy hybrid agricultural tractor, the vehicle's electrical energy supply system starts to work first. A number of storage batteries 7 are installed in the battery compartment 6 inside the vehicle body 2, and these storage batteries 7 are the main source of the vehicle's electrical energy. The storage battery 7 is connected to the inverter 8 through a wire splitting mechanism, and the inverter 8 is installed at the rear end of the battery compartment 6. The main function of the inverter 8 is to convert the direct current in the storage battery 7 into alternating current because the vehicle's drive motor 101 needs alternating current to work normally. When the vehicle starts, the inverter 8 supplies power to the drive motor 101 through the auxiliary drive line 11. The drive motor 101 is installed at the right rear end of the bottom seal seat 106 inside the vehicle body 2, and its drive end is installed with an electric drive gear 102. When the drive motor 101 receives the alternating current provided by the inverter 8, it starts to rotate, and the power is transmitted to the transmission gear 103 through the electric drive gear 102. The transmission gear 103 meshes with the power transmission rod 113, and the power is further transmitted to the oil drive gear 104. The oil drive gear 104 meshes with the axle gear 105 on the rotating shaft 107, and finally the power is transmitted to the drive rear wheel 5, enabling the vehicle to drive normally.

[0030] During the vehicle's driving process, if deceleration or braking is required, the drive motor 101 will switch to the generator mode. At this time, the kinetic energy of the vehicle is converted into electrical energy through the drive motor 101. The inverter 8 comes into play again, converting the alternating current generated by the drive motor 101 into direct current and storing this electrical energy back into the storage battery 7. This process not only reduces the working burden of the braking system but also effectively recovers energy, improving the vehicle's energy utilization efficiency.

[0031] To improve the vehicle's maneuverability and flexibility, especially in muddy or complex farmland environments, the new energy hybrid agricultural tractor is equipped with an electric-assisted steering mechanism. When the driver issues a steering command through the operation cab 1, the storage battery 7 supplies power to the steering motor 201 through the steering line 10. The steering motor 201 is installed in the middle position of the steering platform 213, and a steering gear disk 202 is installed at its output end. After the steering motor 201 starts, the steering gear disk 202 begins to rotate. The steering gear disk 202 drives the transmission gear disks 204 on both sides through the meshing relationship. The transmission gear disks 204 are fixedly installed at both ends of the transverse guide rod 203, and their rotation drives the movement of the transverse guide rod 203. The movement of the transverse guide rod 203 further drives the rotation of the long rod 206. A follower gear disk 205 is installed at one end of the long rod 206 close to the steering platform 213, and the rotation of the follower gear disk 205 drives the movement of the telescopic end of the telescopic rod 208.

[0032] The telescopic end of the telescopic rod 208 is connected to the support plate 210 through the connecting turntable 209. The rotation of the follower gear disk 205 adjusts the angle of the support plate 210 at the front end of the fixed long plate 212 through the telescopic action of the telescopic rod 208. A connecting turntable 209 is fixedly installed on the outside of the support plate 210, and a steering shaft 211 is fixedly installed on the relative outer surface of the connecting turntable 209. As the angle of the support plate 210 is adjusted, the steering shaft 211 rotates accordingly to achieve assisted steering.

[0033] In addition to the electric drive system, the new energy hybrid agricultural tractor is also equipped with a traditional fuel engine 108. The engine 108 is installed at the front left of the bottom sealing seat 106, and its output end is connected to the oil drive gear 104 through the power transmission rod 113. The engine 108 provides traditional fuel power and is usually used in high-load working conditions, such as when the tractor is plowing or driving on muddy sections. When high-load power output is required, the engine 108 starts and begins to work. The output end of the engine 108 transmits power to the oil drive gear 104 through the power transmission rod 113. The oil drive gear 104 meshes with the axle gear 105 on the rotating shaft 107, and finally transmits the power to the drive rear wheels 5. This design allows the engine 108 and the drive motor 101 to work either independently or in cooperation, thus providing efficient power output and energy utilization.

[0034] A transmission cam 112 is fixedly installed on the outer side of the power transmission rod 113, a fixed seat 109 is fixedly installed at the front end of the engine 108, and a driving cam 110 is fixedly installed at its output end. A reduction cam 111 is rotatably installed on the left side of the driving cam 110 on the fixed seat 109. Both the transmission cam 112 and the reduction cam 111 are engaged with the driving cam 110. This design ensures that the power of the engine 108 and the drive motor 101 can be efficiently transmitted to the drive rear wheels 5, enabling the vehicle to maintain optimal performance under different working conditions.
