Description

Technical Field

[0001] The utility model relates to a system, in particular to a driving, steering, suspension and floating system for a forklift, and belongs to the driving field of the forklift. Background Art

[0002] The load-bearing system of the forklift product cannot use the three-point load-bearing form of two points at the front and one point at the back commonly used in transport trucks because the load needs to be lifted to a higher height. In order to increase stability, the rear support is changed from one point to three points, and universal auxiliary wheels are added.

[0003] If there is no suspension floating device between the drive wheel 1-2 and the frame 1-1, but the drive wheel 1-2 is directly installed on the frame 1-1, then adding the universal auxiliary wheel 1-3 will cause problems. If the ground is flat, the drive wheel 1-2 and the universal auxiliary wheel are in contact with the ground at the same time, and the universal auxiliary wheel 1-3 ensures the stability of the stacker, the drive wheel 1-2 can provide sufficient driving force to ensure the normal use of the stacker, see Figure 1 .

[0004] If the ground is uneven and concave, the auxiliary wheels on both sides will touch the ground but be suspended in the air. Although the stability of the forklift is no problem, the driving wheels will not provide driving force and the forklift will not work properly. Figure 2 .

[0005] Similarly, if the ground is convex, although the drive wheel is still in contact with the ground and can provide sufficient driving force, the universal auxiliary wheel will be suspended in the air, the stability of the forklift cannot be guaranteed, and the forklift cannot work safely. Figure 3 .

[0006] In order to avoid the above situation, a structure without universal auxiliary wheels can be used. With only one driving wheel and no universal auxiliary wheels on both sides, the phenomenon caused by uneven ground will not occur. However, since the forklift has high requirements for stability and safety during operation, universal auxiliary wheels must be installed. In order to solve the above problems, the method currently used is: the driving wheel is installed on the frame through a suspension floating device, and the driving wheel and the frame can move relative to each other in the vertical direction, which can ensure that the driving wheel universal auxiliary wheel can contact the ground at the same time under any terrain.

[0007] Currently, most suspension floating devices adopt a double guide column and guide sleeve structure. Due to the high requirements on the position and parallelism between the guide column and guide sleeve, and the fact that the vertical movement axis of the suspension floating device does not coincide with the steering axis of the drive wheel, it is easy to get stuck during use, which increases the difficulty of processing and assembly and the high production cost.

[0008] The drive suspension system adopts a structure different from the currently commonly used suspension floating device, overcomes the common shortcomings, has a simple structure, low production cost, and is easy to assemble and debug. Utility Model Content

[0009] The utility model aims to overcome the above-mentioned deficiencies in the prior art and to provide a driving steering suspension floating system for a forklift which has a simple and reasonable structural design, is safe and reliable, has a low production cost, and is convenient for assembly, disassembly and debugging.

[0010] The technical solution adopted by the utility model to solve the above-mentioned problem is: the driving steering suspension floating system for a forklift comprises a steering handle, a motor connecting seat and a dummy motor, the steering handle is connected to the motor connecting seat, the motor connecting seat is installed on the dummy motor, and is characterized in that it also comprises a spring upper pressure partition, a compression spring, a spring lower pressure gasket, a steering bearing, a driving wheel support plate, a steering connecting seat weldment and a driving wheel, the compression spring is arranged between the spring upper pressure partition and the spring lower pressure gasket, the dummy motor and the driving wheel support plate are fixed on the steering bearing, the spring lower pressure gasket is installed on the steering connecting seat weldment, and the steering connecting seat weldment is connected to the driving wheel.

[0011] Preferably, the utility model further comprises bolt one, and the motor connecting seat is installed on the dummy motor by bolt one.

[0012] Preferably, the utility model further comprises a second bolt, and the dummy motor is fixed to the inner ring of the steering bearing together with the driving wheel support plate by the second bolt.

[0013] Preferably, the utility model further comprises bolt three, and the steering connection seat weldment is connected to the driving wheel via bolt three.

[0014] Preferably, the utility model further comprises a shaft spring retaining ring, wherein the shaft spring retaining ring is arranged on the upper part of the steering connection seat weldment.

[0015] Preferably, the steering handle, motor connection seat, dummy motor, steering connection seat weldment and driving wheel of the utility model rotate relative to the frame with the rotation axis of the steering bearing as the rotation axis to complete the steering function.

[0016] Compared with the prior art, the utility model has the following advantages and effects: the overall structural design is simple and reasonable, safe and reliable, the production cost is low, and the assembly and debugging are easy; a single guide device is adopted, the number of parts is small, and the production, assembly and debugging will be simpler and more convenient; at the same time, the guide axis is coaxial with the driving wheel steering axis, which overcomes the problem of easy jamming of the up and down floating caused by the non-coaxial guide axis and the driving wheel steering axis of the current double guide and multi-guide devices, thereby improving the reliability of the work.

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0026] Example

[0027] See also Figures 4 to 6 The driving steering suspension floating system for a forklift in this embodiment mainly includes a steering handle 1, a motor connecting seat 4, a dummy motor 6, a spring upper pressure partition 7, a compression spring 8, a spring lower pressure gasket 9, a steering bearing 10, a driving wheel support plate 11, a steering connecting seat weldment 13 and a driving wheel 14. The steering handle 1 is connected to the motor connecting seat 4, the motor connecting seat 4 is installed on the dummy motor 6, the compression spring 8 is arranged between the spring upper pressure partition 7 and the spring lower pressure gasket 9, the dummy motor 6 and the driving wheel support plate 11 are fixed on the steering bearing 10, the spring lower pressure gasket 9 is installed on the steering connecting seat weldment 13, and the steering connecting seat weldment 13 is connected to the driving wheel 14.

[0028] The driving suspension system will complete the driving, steering and floating buffer functions of the stacker. The system is installed and connected to the frame through the steering bearing 10. The dummy motor 6 is fixed to the inner ring of the steering bearing 10 by the driving wheel support plate 11 through the bolts 2-5. The motor connecting seat 4 is installed on the dummy motor (6) through the bolts 1-3. Therefore, the steering handle 1, the motor connecting seat 4, and the dummy motor 6 cannot move vertically up and down relative to the frame, but can rotate relative to the frame with the rotation axis of the steering bearing 10 as the rotation axis.

[0029] At the same time, the steering connecting seat weldment 13 is connected to the driving wheel 14 by bolt three 12. The connection between the steering connecting seat weldment 13 and the driving wheel support plate 11 has a radial platform structure, which limits the relative rotation between the two parts, but the relative movement between the axial directions is not restricted. In summary, the steering handle 1, the motor connecting seat 4, the dummy motor 6, the steering connecting seat weldment 13, and the driving wheel 14 can rotate relative to the frame with the rotation axis of the steering bearing 10 as the rotation axis to complete the steering function.

[0030] In the vertical direction, since the steering connection seat weldment 13 has an axial stop, the spring pressure gasket 9 is installed on the steering connection seat weldment 13. When it contacts the stop, it can no longer go down. The force acting on the forklift frame is transmitted to the drive wheel 14 through the steering bearing 10, the dummy motor 6, the spring upper pressure partition 7, the compression spring 8, the spring lower pressure gasket 9, and the steering connection seat weldment 13. Due to the compressibility of the compression spring 8, there is floating in the vertical direction between the drive wheel 14 and the frame, completing the function of suspension floating.

[0031] The driving steering suspension floating system of this embodiment adopts a single guide device. Compared with the currently commonly used double guide or even multi-guide devices, it has a simpler structure and fewer parts, and the production, assembly and debugging will be simpler and more convenient. At the same time, the guide axis is coaxial with the steering axis of the driving wheel 14, which overcomes the problem that the up and down floating is easy to get stuck due to the misalignment of the guide axis of the current double guide and multi-guide devices and the steering axis of the driving wheel, thereby improving the reliability of the work.

[0032] Through the above description, those skilled in the art can already implement it.

[0033] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
