Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, and in particular to a drive suspension, drive device and transfer equipment. Background Technology

[0002] Existing transfer equipment typically employs a rigid drive structure, with the drive wheels directly fixed to the chassis frame and powered by a drive motor. This rigid connection structure easily transmits vibrations from uneven ground directly to the entire device during movement, resulting in significant overall vibration. Especially when loading cargo, ground vibrations can cause the cargo to sway or even shift, impacting transfer efficiency and safety.

[0003] Traditional drive structures often employ simple spring-loaded buffer structures, but these structures typically use only a single elastic element and lack effective guiding and buffering adjustment mechanisms. The buffering effect of a single elastic element is limited, and it is prone to fatigue and attenuation during long-term use. Furthermore, it cannot be adjusted according to different load conditions, resulting in significant differences in the shock absorption effect of the transfer equipment under no-load and full-load conditions.

[0004] Therefore, there is an urgent need to propose a drive suspension, drive device, and transfer equipment to solve the above problems. Utility Model Content

[0011] Furthermore, the buffer mechanism includes a buffer shaft, an adjusting member, an adjusting block, and an elastic component;

[0012] The hub mounting bracket has a through hole; the buffer shaft passes through the through hole and is slidably connected to the through hole; one end of the buffer shaft is connected to a chassis frame, and the other end extends to the outside of the hub mounting bracket and is connected to the connecting plate; the adjusting member is detachably connected to the buffer shaft; the adjusting block and the elastic component are both sleeved on the buffer shaft and located inside the through hole; one end of the elastic component is connected to the inner wall of the through hole, and the other end is connected to the adjusting block; the adjusting block is slidably connected to the buffer shaft; the adjusting block is located between the adjusting member and the elastic component.

[0013] Furthermore, the outer diameter of the adjusting member is smaller than the inner diameter of the through hole.

[0014] Furthermore, the adjusting component includes an adjusting nut; the adjusting nut is threadedly connected to the buffer shaft.

[0015] Furthermore, the guiding mechanism is parallel to the buffer mechanism.

[0019] Through the above technical solution, this utility model has the following beneficial effects:

[0020] By employing a drive suspension structure that combines drive components, wheel hub mounting brackets, guiding mechanisms, and buffer mechanisms, an elastic connection is formed between the drive wheels and the chassis frame.

Detailed Implementation

[0026] The following is a more detailed description of a drive suspension, drive device, and transfer equipment according to the present invention, with reference to the accompanying drawings, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0027] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0028] like Figures 1-3 As shown, this utility model embodiment proposes a convenient and practical drive suspension, including: a drive component 1021, a hub mounting bracket 1022, a bearing axle seat 10210, a coupling 10212, a guide mechanism, and a buffer mechanism.

[0029] Specifically, the bearing seat 10210 is installed in the middle of the hub mounting frame 1022, and a bearing 10211 is sleeved on the outer side of the bearing seat 10210; the coupling 10212 is sleeved on the bearing 10211 and connected to the drive wheel 102; the output shaft of the drive member 1021 passes through the hub mounting frame 1022 and is connected to the coupling 10212; the guide mechanism and the buffer mechanism are both located at the ends of the hub mounting frame 1022.

[0030] In this embodiment, the wheel hub mounting bracket 1022 serves as the basic support structure of the drive suspension, supporting the drive component 1021 and the drive wheel 102, and providing mounting positions for the guide mechanism and the buffer mechanism. The wheel hub mounting bracket 1022 can be made of metal materials, such as aluminum alloy or steel, possessing sufficient strength and rigidity to withstand various stresses during the driving process.

[0031] In one specific example, the hub mounting bracket 1022 can be designed in a "U" shape, with the central area used to install the bearing axle seat 10210 and the drive component 1021, and the two ends used to install the guide mechanism and the buffer mechanism, respectively. This structural arrangement can improve the overall stability of the hub mounting bracket 1022, while providing sufficient support for the drive wheel 102.

[0032] Preferably, the driving component 1021 is a motor, used to provide power to the drive wheel 102. The driving component 1021 is connected to the coupling 10212 via its output shaft, thereby driving the drive wheel 102 to rotate. The power of the driving component 1021 can be selected according to the load requirements of the transfer equipment. As those skilled in the art will know, the power of the driving component 1021 can be set according to actual needs, and the driving component 1021 also includes other embodiments besides this embodiment, such as a hydraulic motor, a pneumatic motor, etc.

[0033] In one embodiment, the guiding mechanism includes a guide shaft 1023 and a guide bearing 1024. Specifically, the guide bearing 1024 is disposed inside the wheel hub mounting bracket 1022 and perpendicular to the wheel hub mounting bracket 1022; the guide shaft 1023 passes through the guide bearing 1024; the guide bearing 1024 is slidably connected to the guide shaft 1023 and moves up and down along the side wall of the guide shaft 1023; one end of the guide shaft 1023 is connected to a chassis frame 101, and the other end extends outside the guide bearing 1024. The guiding mechanism ensures that the wheel hub mounting bracket 1022 maintains good orientation during up and down movement, prevents lateral displacement of the wheel hub during movement, and enhances the driving stability of the drive wheel 102.

[0034] In this embodiment, the guide shaft 1023 can be made of high-strength steel, and its surface can be hardened to improve wear resistance and service life. The guide bearing 1024 can be a rolling bearing or a sliding bearing structure, maintaining an appropriate fit clearance with the guide shaft 1023 to improve the smoothness of vertical movement.

[0035] Preferably, this embodiment further includes a connecting plate 1029; the other end of the guide shaft 1023 is connected to the connecting plate 1029 together with the buffer mechanism. The connecting plate 1029 can be made of sheet metal and has sufficient strength and rigidity. The connecting plate 1029 connects the ground-facing ends of the guide mechanism and the buffer mechanism into a single unit, forming a cooperating overall structure.

[0036] In one specific example, the connecting plate 1029 may have a structure with multiple reinforcing ribs, which can improve the rigidity of the connecting plate 1029 and reduce deformation that may occur during operation. At the same time, the connecting plate 1029 may be provided with multiple mounting holes to facilitate connection with the guide shaft 1023 and the buffer shaft 1025, and the connection position can be adjusted as needed.

[0037] In this embodiment, the connection plate 1029 enables the guide mechanism and the buffer mechanism to work together, allowing the two mechanisms to move synchronously and enhancing the structural stability and motion synchronization of the entire drive suspension.

[0038] In one embodiment, the buffer mechanism includes a buffer shaft 1025, an adjusting member 1026, an adjusting block 1027, and an elastic member 1028. Specifically, the hub mounting bracket 1022 has a through hole; the buffer shaft 1025 passes through the through hole and is slidably connected to the through hole; one end of the buffer shaft 1025 is connected to a chassis frame 101, and the other end extends outside the hub mounting bracket 1022 and is connected to the connecting plate 1029; the adjusting member 1026 is detachably connected to the buffer shaft 1025; the adjusting block 1027 and the elastic member 1028 are both sleeved on the buffer shaft 1025 and located inside the through hole; one end of the elastic member 1028 is connected to the inner wall of the through hole, and the other end is connected to the adjusting block 1027; the adjusting block 1027 is slidably connected to the buffer shaft 1025; the adjusting block 1027 is located between the adjusting member 1026 and the elastic member 1028.

[0039] The through hole is a through hole provided on the hub mounting bracket 1022, used for the passage of the buffer shaft 1025 and the installation of the elastic component 1028. The inner wall of the through hole can be smoothed to reduce friction between the buffer shaft 1025 and the elastic component 1028.

[0040] In a specific example, the elastic component 1028 may be a compression spring, a rubber buffer block, or a composite spring structure. When a compression spring is selected, different spring stiffnesses and materials can be chosen as needed, such as carbon spring steel, alloy spring steel, etc. The spring stiffness can be matched according to the load conditions of the transfer equipment; a higher stiffness is suitable for heavy loads, and a lower stiffness is suitable for light loads. Those skilled in the art will understand that the material and stiffness of the elastic component 1028 can be set according to actual needs, and the elastic component 1028 also includes other embodiments besides this one.

[0041] In this embodiment, the buffer mechanism, through the elastic component 1028, provides a cushioning effect when the drive wheel 102 encounters uneven ground, reducing the transmission of vibration to the entire transfer equipment and improving the stability of the transfer equipment and the safety of the goods. Simultaneously, through the cooperation of the adjusting component 1026 and the adjusting block 1027, the buffering effect can be adjusted according to different load conditions, thereby enhancing the adaptability of this device.

[0042] In this embodiment, the outer diameter of the adjusting member 1026 is smaller than the inner diameter of the through hole, so that the adjusting member 1026 will not interfere with the inner wall of the through hole when the buffer shaft 1025 moves up and down. This arrangement allows the adjusting member 1026 to pass freely through the through hole during the movement of the wheel hub mounting bracket 1022 without restricting the range of motion of the wheel hub mounting bracket 1022.

[0043] Preferably, the adjusting member 1026 includes an adjusting nut; the adjusting nut is threadedly connected to the buffer shaft 1025. The adjusting nut has an internal thread that matches the buffer shaft 1025. By rotating the adjusting nut, its position on the buffer shaft 1025 can be changed, thereby altering the pre-compression of the elastic member 1028 and adjusting the buffering effect.

[0044] In this embodiment, the guiding mechanism is parallel to the buffer mechanism. Furthermore, one end of both the guiding mechanism and the buffer mechanism is connected to a chassis frame 101, and the other end is located on the same horizontal plane. The guiding mechanism and the buffer mechanism maintain a consistent spatial orientation, ensuring that the guide shaft 1023 and the buffer shaft 1025 are subjected to the same force direction, thus enabling better collaborative operation.

[0045] Furthermore, this embodiment also proposes a drive device, including a drive wheel 102 and a drive suspension as described above; the drive suspension is connected to the drive wheel 102 to carry and drive the drive wheel 102; the drive wheel 102 is located in the middle of the hub mounting bracket 1022 of the drive suspension.

[0046] Furthermore, this embodiment also proposes a transfer device, including a drive unit and a chassis frame 101 as described above; the chassis frame 101 is used to support and fix the drive unit; the drive suspension in the drive unit is connected to the chassis frame 101 to form a drive system with shock absorption function; the drive system provides the transfer device with travel power.

[0047] In this embodiment, when the transfer equipment is moving on the ground, the drive component 1021 drives the coupling 10212 to rotate via the output shaft. The coupling 10212 then drives the drive wheel 102 to rotate, propelling the entire transfer equipment forward. When encountering uneven ground, the drive wheel 102 will experience vertical displacement. At this time, the hub mounting bracket 1022 forms an elastic connection with the chassis frame 101 through the guide mechanism and the buffer mechanism.

[0048] Specifically, when the drive wheel 102 encounters a protrusion, the upward impact force causes the hub mount 1022 to move upward along the guide shaft 1023, while simultaneously compressing the elastic component 1028 in the buffer mechanism. The compression of the elastic component 1028 absorbs some of the impact energy, reducing the transmission of the impact force to the chassis frame 101. The guide shaft 1023 and the guide bearing 1024 ensure that the hub mount 1022 maintains a stable orientation during its vertical movement, preventing lateral deviation or twisting.

[0049] When the drive wheel 102 passes the protrusion, the elastic component 1028 releases the stored energy, pushing the hub mounting bracket 1022 back to its original position, keeping the drive wheel 102 in contact with the ground. Throughout the process, the guiding mechanism and the buffer mechanism work together to improve the directional stability of the drive wheel 102 and provide effective vibration absorption.

[0050] Furthermore, by adjusting the adjusting element 1026, the pre-compression of the elastic element 1028 can be changed, thereby adjusting the cushioning effect. Under full load, the pre-compression can be increased to provide stronger support; under no-load conditions, the pre-compression can be decreased to achieve a better cushioning effect. This adjustability allows the drive suspension to adapt to different load conditions and operating environments.

[0051] In summary, the drive suspension, drive device, and transfer equipment proposed in this utility model have the following advantages:

[0052] By employing a drive suspension structure that combines drive components, wheel hub mounting brackets, guiding mechanisms, and buffer mechanisms, an elastic connection is formed between the drive wheels and the chassis frame. This effectively absorbs and buffers vibrations caused by uneven ground, preventing direct transmission of vibrations to the entire transfer equipment and significantly improving equipment stability and cargo transportation safety. Simultaneously, the design of the bearing axle seats and couplings simplifies the connection structure between the drive components and drive wheels, thereby reducing installation precision requirements, minimizing component wear, and extending equipment lifespan.

[0053] Furthermore, the coordinated design of the guiding and buffering mechanisms, along with the connecting plate, forms an integrated structure, enabling the wheel hub mounting bracket to provide stable guidance and effective cushioning during vertical bumps. In particular, the combined application of adjusting components, adjusting blocks, and elastic parts in the buffering mechanism allows for adjustable cushioning effects, enabling the drive suspension to adapt to different load conditions. This ensures stable operation of the transfer equipment under various working conditions, thus meeting the demands of high-intensity, long-term, and multi-condition applications.

[0054] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
