Description

Technical Field

[0001] The present invention relates to port container transport equipment, and more particularly to a centrally mounted distributed drive automated container transport vehicle. Background Art

[0002] With the rapid development of the logistics industry, higher requirements are placed on the efficiency and intelligence level of transportation equipment. Traditional container transport vehicles (AGVs) often have problems such as insufficient driving force and low degree of automation, which makes it difficult to meet the needs of modern logistics and transportation. The disadvantages of traditional container trucks are mainly reflected in the following aspects:

[0003] 1) Economical: As traditional container trucks use fuel as a power source, their operating costs are greatly affected by fluctuations in international oil prices. Compared with electric vehicles, fuel costs are usually higher.

[0004] 2) Power performance: Although fuel engines can provide higher power in some cases, their power response is usually not as fast as that of electric vehicles. Electric vehicles have a faster starting speed. Fuel engines usually cannot achieve zero or low emission levels of electric vehicles in terms of emissions, which puts a certain pressure on environmental protection.

[0005] 3) Daily use and maintenance. The maintenance cost of fuel engines is usually higher, including regular replacement of engine oil, air filter, etc., as well as possible repair costs.

[0006] 4) Service life (battery life). Although traditional container trucks do not have the battery life problem of electric vehicles, their engines and related components will gradually wear and age as time goes by, affecting the performance and life of the entire vehicle.

[0037] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0038] Combination Figure 1 and Figure 2 As shown, a central distributed drive automated container transport vehicle provided by the present invention includes a frame 1, a load-bearing bridge 2, a control cabinet 3, a drive motor 4, a drive steering bridge 5 and a power cabinet 6.

[0039] Two sets of load-bearing bridges 2 are provided, which are evenly distributed at the bottom of the frame 1 and close to the two end positions of the frame 1 .

[0040] Four sets of driving steering axles 5 are provided, and are arranged in a 2×2 array near the bottom middle position of the frame 1 .

[0041] Each set of driving steering axles 5 is provided with a driving motor 4 for driving and controlling the corresponding driving steering axle 5 .

[0042] The control cabinet 3 and the power cabinet 6 are both installed at the bottom of the frame 1. The control cabinet 3 is connected to the drive motor 4 to control the start and stop of the drive motor 4. The power cabinet 6 provides power for the central distributed drive automated container transport vehicle of the present invention.

[0043] The four sets of driving steering axles 5 are symmetrically arranged along the longitudinal and transverse central axes of the vehicle frame 1 .

[0044] The driving steering bridge 5 is located at the output end of the driving motor 4, and its main function is to change the speed and torque from the driving motor 4 and transmit it to the wheels 52 to drive the central distributed drive automated container transport vehicle of the present invention.

[0045] Since the driving steering axle 5 needs to transmit a large power, the frame 1 at the installation position of the driving steering axle 5 needs to be designed with sufficient strength and rigidity to withstand the power load from the driving steering axle 5 .

[0046] Combination Figure 2 As shown, the load-bearing bridge 2 includes a suspension assembly, a bridge housing, an axle 21 and wheels 22 .

[0047] The upper part of the suspension assembly is connected and fixed to the crossbeam or longitudinal beam on the vehicle frame 1, and the lower part is connected and fixed to the bridge housing.

[0048] The axle 21 is mounted on a bearing seat of the bridge housing, and both ends of the axle 23 are located at both sides of the bridge housing 22 respectively.

[0049] Two wheels 24 are provided, and are connected to both end positions of the axle 23 , respectively.

[0050] Combination Figure 3 As shown, the driving steering axle 5 includes a suspension assembly 51 , an axle 52 and wheels 53 .

[0051] The suspension assembly 51 is connected and fixed to the crossbeam or longitudinal beam on the frame 1 by bolts and nuts.

[0052] The axle 52 is connected and fixed to the suspension assembly 51 .

[0053] Two wheels 52 are provided, and are connected and fixed to both end positions of the axle 52 , respectively.

[0054] The suspension assembly 51 includes a slewing bearing 511 , a driving axle 512 and a telescopic cylinder 513 .

[0055] The slewing bearing 511 is connected and fixed to the cross beam or longitudinal beam of the vehicle frame 1 .

[0056] One end of the telescopic oil cylinder 513 is connected and fixed to the slewing bearing 511 , and the other end is connected and fixed to the driving axle 512 .

[0057] The drive axle 512 is fixedly connected to the axle 52 .

[0058] The driving motor 4 is mounted on the driving axle 512 .

[0059] The lengths of the axles 52 in the four sets of driving steering bridges 5 are consistent and are all smaller than the length of the axles 23 in the load-bearing bridge 2 .

[0060] The length of the axle 23 in the supporting bridge 2 is adapted to the width of the vehicle frame 1 .

[0061] A control unit is provided in the control cabinet 3, and the control unit includes:

[0062] The sensor is used to monitor the rotation speed, torque and steering angle of the wheels 53 on the driving steering axle 5.

[0063] The actuator is used to drive and control the drive motor 4.

[0064] ECU is used to receive signals from sensors and calculate control instructions.

[0065] The control cabinet 3 serves as the control center of the central distributed drive automated container transport vehicle of the present invention, and is responsible for receiving and processing various control signals to realize the automated control of the central distributed drive automated container transport vehicle of the present invention. Through relevant control algorithms and sensor technologies, the control cabinet 3 can monitor the state of the central distributed drive automated container transport vehicle of the present invention in real time, adjust the output of the drive motor 4, and ensure the smooth operation of the central distributed drive automated container transport vehicle of the present invention. In actual applications, users can set the transport route and transport parameters according to specific needs, and realize automated control and scheduling through the control cabinet 3.

[0066] The central distributed drive automated container transport vehicle of the present invention also has fault self-diagnosis and alarm functions, which can timely discover and handle potential problems and improve the safety and reliability of transportation.

[0067] The driving steering axle 5 of the mid-mounted distributed drive automated container transport vehicle of the present invention adopts a mid-mounted distributed drive design, which can provide powerful driving force and flexible steering performance, so that the mid-mounted distributed drive automated container transport vehicle of the present invention can maintain a stable driving state under various road conditions.

[0068] The connection structure between the driving steering axle 5 and the frame 1 enables the central distributed drive automated container transport vehicle of the present invention to have good steering and stability performance and to adapt to different transport requirements and environmental conditions.

[0069] The driving steering axle 5 mainly bears the vertical load of the central distributed drive automated container transport vehicle of the present invention, and bears the longitudinal force and lateral force and the torque caused by them. During the driving process of the central distributed drive automated container transport vehicle of the present invention, the driving steering axle 5 is also responsible for realizing the steering function of the central distributed drive automated container transport vehicle of the present invention. Therefore, its load-bearing weight is affected by the overall weight and driving conditions of the central distributed drive automated container transport vehicle of the present invention. In some specially designed vehicles, such as heavy-duty carriers, the load-bearing weight of the driving steering axle 5 may be relatively large, but it usually does not exceed a specific proportion of the total weight of the vehicle.

[0070] Since the driving steering axle 5 needs to realize the steering function, the structural design of the driving steering axle 5 is relatively complex, and it needs to withstand various forces and moments. Therefore, the driving steering axle 5 needs to have high strength and rigidity to ensure its stability and durability. The strength design of the driving steering axle 5 usually takes into account factors such as the strength of the material, the rationality of the structure, and the precision of the manufacturing process.

[0071] The load-bearing bridge 2 mainly bears the vertical load of the vehicle and transmits power (in the case of a drive axle). For a drive axle, it also needs to withstand the torque and force generated by the engine and transmission system. Therefore, the load-bearing weight of the load-bearing bridge is usually large, especially in heavy vehicles, and its load-bearing weight may be close to or reach half of the total weight of the vehicle or more.

[0072] The load-bearing bridge 2 also needs to have high strength and rigidity to withstand the vertical load of the central distributed drive automated container transport vehicle of the present invention and various forces and moments during the power transmission process. For the drive steering bridge 5, its strength design also needs to consider the torque and power output requirements of the transmission system. In heavy vehicles, the strength of the load-bearing bridge 2 is particularly important to ensure the stability and safety of the vehicle under various complex working conditions.

[0073] The power cabinet 6 provides a stable and reliable power supply for the central distributed drive automated container transport vehicle of the present invention, ensuring the continuous operation of the vehicle.

[0074] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
