Description

Technical Field

[0001] This invention relates to the field of automotive suspension technology, specifically to a rubber suspension structure for a port automated container transport vehicle. Background Technology

[0002] The suspension is a general term for all force-transmitting connection devices between the car frame and the axle. Its function is to transmit the forces and torques acting between the wheels and the frame, and to buffer the impact forces transmitted from uneven road surfaces to the frame or body, and reduce the resulting vibrations, so as to ensure that the car can drive smoothly. The car suspension is mainly composed of elastic elements, shock absorbers and guiding mechanisms. According to the elastic elements, car suspensions can be classified as leaf spring suspension, coil spring suspension, air spring suspension and rubber spring suspension.

[0003] The core component of a rubber spring suspension is the rubber spring, including variable stiffness rubber springs and shear rubber springs. It is connected to the axle through structures such as equalizer beams, hangers, and triangular support seats. Compared with traditional leaf spring suspensions, it can significantly reduce weight, effectively reducing fuel consumption and carbon dioxide emissions. At the same time, the rubber material can efficiently absorb road impacts, reducing vehicle bumps. Rubber components are also corrosion-resistant, require no lubrication, have a simple and robust structure, and have a longer lifespan than traditional metal suspensions. It is suitable for special vehicles and industrial vehicles, such as vehicles used for container transport in ports.

[0004] However, it also has certain shortcomings in actual use. For example, rubber components are easily damaged by the external environment. During the long-term parking of the transport vehicle, the rubber components still provide support for the frame and come into contact with the external environment, which will accelerate the damage of the rubber components and reduce their service life. Summary of the Invention

[0005] The purpose of this invention is to provide a rubber suspension structure for a port automated container transport vehicle to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to a rubber suspension structure for an automated container transport vehicle in a port, comprising a balance beam, which is composed of two balance supports and a housing component. Both balance supports are mounted on the housing component and are symmetrically distributed on both sides of the housing component. A rotating component is mounted on the housing component, and a spring support is mounted on the rotating component. A frame saddle is mounted above the balance beam. A connecting seat is mounted on one side of the spring support. Two shear rubber springs and a variable stiffness rubber spring are mounted on the spring support. Both shear rubber springs are connected to the connecting seat and are inclined. The two shear rubber springs are symmetrically arranged on both sides of the variable stiffness rubber spring.

[0008] Furthermore, the storage component is made of an arc-shaped steel plate, and two conical steel plates are installed on the inner wall of the arc-shaped steel plate to increase the rigidity of the arc-shaped steel plate.

[0009] Furthermore, baffles are provided on both sides of the curved steel plate. The top of the baffles is higher than the top of the curved steel plate and lower than the frame saddle. The baffles and the curved steel plate are fastened together with bolts.

[0010] Furthermore, the storage component is provided with a rotating shaft, which passes through two tapered steel plates and is rotatably connected to the two tapered steel plates. A drive motor is installed on one of the baffles. One end of the rotating shaft extends outside the baffle and is connected to the output shaft of the drive motor. The rotating shaft passes through the rotating component and is fixedly connected to the rotating component.

[0011] Furthermore, the rotating component consists of two connecting vertical plates and an arc-shaped support plate. Both connecting vertical plates are mounted on spring supports and are connected to the rotating shaft. The arc-shaped support plate is located inside the receiving component and contacts the inner wall of the arc-shaped steel plate.

[0012] Furthermore, an active area is provided between the two connecting vertical plates, and an active area is provided between the two connecting vertical plates and the two tapered steel plates. Multiple heat dissipation slots are provided on the side of the connecting vertical plates near the arc-shaped support plate.

[0013] Furthermore, the side of the connecting seat away from the spring support is set as arc surface one, and the bottom of the frame saddle is set as arc surface two. The outer side of arc surface one and the arc support plate are both adapted to the bottom arc surface two of the frame saddle.

[0014] Furthermore, positioning grooves are provided on the outer surfaces of both the first arc surface and the arc-shaped support plate, and positioning blocks are installed on the second arc surface, with the positioning blocks matching the positioning grooves.

[0015] Furthermore, a straightening component is installed on the rotating component. The straightening component consists of a connecting frame and a straightening plate. The connecting frame is installed on the rotating component, and the straightening plate is installed on the connecting frame. The number of straightening plates is set to multiple, and they are distributed in two groups. The straightening plates are folded, and the two groups of straightening plates are symmetrically distributed.

[0016] Furthermore, both the spring support and the rotating seat are made of heat-conducting material, and the spring support is provided with heat-conducting vents.

[0017] The present invention has the following beneficial effects:

[0018] (1) Compared with the traditional rubber suspension structure, the present invention innovates the balance beam on it by dividing the integrally constructed balance beam into three sections, namely two side balance supports and a central arc-shaped steel plate. This allows a storage chamber to be constructed on the balance beam. With the assistance of the tapered steel plates on both sides, the storage chamber has a good storage effect. When the transport vehicle is not in use, the rotating part is rotated by the drive motor, which changes the position between the connecting seat and the arc-shaped support plate. This allows the shear rubber spring and the variable stiffness rubber spring to enter the storage part. The storage part protects the shear rubber spring and the variable stiffness rubber spring, reduces the damage to the shear rubber spring and the variable stiffness rubber spring caused by the external environment, and extends the service life of the shear rubber spring and the variable stiffness rubber spring.

[0019] (2) With the above-mentioned function of converting the connecting seat and the arc-shaped support plate, the present invention can form a rigid support through the action of two connecting vertical plates, the arc-shaped support plate, the rotating shaft and the tapered steel plate, which is used to balance the support of the beam on the frame saddle, so that there is no need for shear rubber springs and variable stiffness rubber springs to provide support, further improving the protection of shear rubber springs and variable stiffness rubber springs. At the same time, when the shear rubber springs and variable stiffness rubber springs are damaged during driving, the position between the connecting seat and the arc-shaped support plate can be changed to continue to provide support force for the frame saddle, allowing the vehicle to continue to drive for a distance, which is convenient for vehicle maintenance. At the same time, it avoids putting too much pressure on the intact shear rubber springs or variable stiffness rubber springs, which would damage the intact shear rubber springs and variable stiffness rubber springs.

[0020] (3) With the above-mentioned connecting seat and arc support plate being convertible, after the shear rubber spring and variable stiffness rubber spring are damaged, the shear rubber spring and variable stiffness rubber spring can be rotated into the storage part, and then the baffle and sealing plate can be disassembled. Subsequently, the shear rubber spring and variable stiffness rubber spring can be replaced. During this process, with the support of the two connecting vertical plates, arc support plate, rotating shaft and tapered steel plate, there is no need to use external tools to provide support for the frame saddle, which can improve the maintenance efficiency of shear rubber spring and variable stiffness rubber spring. Moreover, under this structure, the driver can replace them by himself, reducing maintenance costs.

[0021] (4) By using heat-conducting materials for the rotating component and the spring support, the present invention can promptly dissipate heat from the shear rubber spring and the variable stiffness rubber spring during operation, thereby improving the protection effect of the shear rubber spring and the variable stiffness rubber spring. At the same time, the area between the two connecting vertical plates on the rotating component is set as an active area, and multiple heat dissipation slots are opened on it, thereby further assisting in heat dissipation. In addition, heat dissipation holes are opened on the spring support, which can complete the replacement of internal air with external air through the working deformation of the shear rubber spring, thereby further improving the heat dissipation effect of the shear rubber spring and achieving the protection effect of the shear rubber spring and the variable stiffness rubber spring.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-8 As shown, the present invention is a rubber suspension structure for a port automated container transport vehicle, including a balance beam 1. The balance beam 1 is composed of two balance supports 101 and a storage component 102. The two balance supports 101 are both mounted on the storage component 102 and are symmetrically distributed on both sides of the storage component 102. A rotating component 7 is provided on the storage component 102, and a spring support 8 is provided on the rotating component 7. A frame saddle 5 is provided above the balance beam 1. A connecting seat 9 is provided on one side of the spring support 8. Two shear rubber springs 10 and a variable stiffness rubber spring 11 are provided on the spring support 8. The two shear rubber springs 10 are both connected to the connecting seat 9. The two shear rubber springs 10 are inclined and symmetrically arranged on both sides of the variable stiffness rubber spring 11.

[0036] The storage component 102 is made of an arc-shaped steel plate. A drainage hole is provided at the bottom of the arc-shaped steel plate, so that water can be discharged in time after entering the arc-shaped steel plate. Two conical steel plates 2 are installed on the inner wall of the arc-shaped steel plate to increase the rigidity of the arc-shaped steel plate. One of the conical steel plates 2 has an opening, and a sealing plate 3 is installed in the opening by bolts. The use of the conical steel plate 2 is equivalent to installing a connector on the inner side of the arc-shaped steel plate to connect the two sides of the arc-shaped steel plate and prevent the arc-shaped steel plate from deforming. The conical steel plate 2 is connected to the arc-shaped steel plate by welding. Similarly, the two equalizing supports 101 and the outer wall of the arc-shaped steel plate are also connected by welding.

[0037] Both sides of the curved steel plate are provided with baffles 4. The top of the baffles 4 is higher than the top of the curved steel plate and lower than the frame saddle 5. The baffles 4 and the curved steel plate are fastened together with bolts. The side of the curved steel plate is provided with a positioning groove. A positioning block 14 is installed on the baffles 4. The positioning block 14 is adapted to the positioning groove to improve the connection stability and accuracy between the baffles 4 and the curved steel plate. By setting the baffles 4, the two sides of the curved steel plate can be better protected, reducing the impact of the external environment on the internal environment of the storage component 102.

[0038] The storage component 102 is provided with a rotating shaft 6, which passes through two tapered steel plates 2 and is rotatably connected to the two tapered steel plates 2. A drive motor 17 is installed on one of the baffles 4. One end of the rotating shaft 6 extends to the outside of the baffle 4 and is connected to the output shaft of the drive motor 17. The rotating shaft 6 passes through the rotating component 7 and is fixedly connected to the rotating component 7.

[0039] The rotating component 7 consists of two connecting vertical plates and an arc-shaped support plate 12. Both connecting vertical plates are mounted on the spring support 8 and are connected to the rotating shaft 6. The arc-shaped support plate 12 is located inside the receiving component 102 and is in contact with the inner wall of the arc-shaped steel plate.

[0040] An active area is provided between the two connecting vertical plates and between the two connecting vertical plates and the two tapered steel plates 2. Multiple heat dissipation slots are provided on the side of the connecting vertical plates near the arc-shaped support plate 12. The active area can prevent heat from accumulating. At the same time, the connecting vertical plates are used to increase the heat dissipation surface of the shear rubber spring 10 and the variable stiffness rubber spring 11, thereby improving the heat dissipation effect.

[0041] The side of the connecting seat 9 away from the spring support 8 is set as arc surface one, and the bottom of the frame saddle 5 is set as arc surface two. The outer side of arc surface one and the arc support plate 12 are both adapted to the bottom arc surface two of the frame saddle 5.

[0042] Positioning grooves are provided on the outer surfaces of both the first arc surface and the arc support plate 12. Positioning blocks are installed on the second arc surface. The positioning blocks are adapted to the positioning grooves and are T-shaped. The connecting seat 9 and the arc support plate 12 rotate 180 degrees back and forth. By setting the positioning blocks and positioning grooves, the stability of the connecting seat 9 and the arc support plate 12 after being connected to the frame saddle 5 can be improved, and the instability of the frame saddle 5 can be avoided.

[0043] A straightening component 13 is installed on the rotating component 7. The straightening component 13 consists of a connecting frame and a straightening plate. The connecting frame is installed on the rotating component 7, and the straightening plate is installed on the connecting frame. There are multiple straightening plates, which are distributed in two groups. The straightening plates are folded and the two groups of straightening plates are symmetrically distributed. The outer side of the straightening plate is adapted to the bottom inclined surface 2 of the frame saddle 5. During the rotation of the rotating component 7, when the connecting seat 9 is disengaged from the inclined surface 2, the straightening plate comes into contact with the inclined surface 2, thereby supporting the inclined surface 2. This facilitates the extension of the arc-shaped support plate 12 to the bottom of the inclined surface 2, which plays a conductive role.

[0044] Both the spring support 8 and the rotating seat are made of heat-conducting material, and the spring support 8 is provided with heat-conducting vents. In actual use, since the middle part of the shear rubber spring 10 is generally hollow, the heat-conducting vents are connected to the middle area of ​​the shear rubber spring 10. Thus, during the deformation of the shear rubber spring 10, the airflow in the middle part can be changed. The airflow can be transported through the heat-conducting vents, thereby completing the exchange of airflow in the middle area of ​​the shear rubber spring 10 with the outside airflow and achieving the effect of heat dissipation.

[0045] In this invention, the rubber suspension structure is further provided with a limiting component 15 and a shock absorber 16. The limiting component 15 consists of a telescopic cylinder and a telescopic rod. The telescopic cylinder is rotatably mounted on the tapered steel plate 2, and the telescopic rod is slidably mounted inside the telescopic cylinder. The other end of the telescopic rod is rotatably connected to the frame saddle 5. The limiting component 15 can limit the position of the balance beam 1 and the frame saddle 5. Depending on the actual production situation, the limiting component 15 can also be constructed using a chain. The shock absorber 16 is constructed using existing technology. The shock absorber 16 is rotatably connected to the balance beam 1, and the telescopic shaft of the shock absorber 16 is rotatably connected to the frame saddle 5. The shock absorber 16 can dissipate the force transmitted between the wheel and the frame. All of the above settings are existing technologies.

[0046] When in use, the equalizer beam 1 is first installed on the vehicle, and the frame saddle 5 is connected to the frame with bolts. During use, when force is transmitted between the wheel and the frame, the transmitted force will pass through the shear rubber spring 10 and the variable stiffness rubber spring 11, thereby reducing the transmitted force and ensuring the stability of the frame. The operation mode and effect are the same as the existing rubber frame.

[0047] When not in use, the drive motor 17 can be started to drive the rotating shaft 6 to rotate, thereby driving the rotating component 7 to rotate. During this process, the connecting seat 9 disengages from the frame saddle 5, and the straightening component 13 connects to the frame saddle 5. As the rotation angle of the rotating component 7 increases, the arc-shaped support plate 12 contacts the frame saddle 5 until the arc-shaped support plate 12 and the connecting seat 9 change positions and stop rotating. This allows the shear rubber spring 10 and the variable stiffness rubber spring 11 to be transferred to the storage component 102 for protection, reducing the damage to the shear rubber spring 10 and the variable stiffness rubber spring 11 caused by the external environment. At the same time, when replacing them, only the corresponding baffle 4 and the sealing plate 3 need to be removed for replacement. During the replacement process, the frame saddle 5 is supported by the arc-shaped support plate 12 and the rotating component 7, without the need for external tools, which can improve the replacement efficiency of the shear rubber spring 10 and the variable stiffness rubber spring 11.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
