Description

Technical Field

[0001] This utility model relates to the field of snowplows, and in particular to a steering control device. Background Technology

[0002] A snowplow is a type of engineering machinery specifically designed for clearing snow from roads. It is widely used in urban roads, airport runways, highways, and other locations. When a snowplow is in motion, its bucket inserts into the snow, and the vehicle's forward propulsion shovels up the snow and pushes it to the side of the road or a designated collection area.

[0003] Currently, snowplows generally use a tracked power unit. When reversing, the vehicle steers by rotating two sets of drive wheels in opposite directions. The tracked steering control device includes a reversing cylinder connected to the reversing drive gear. This cylinder switches states through the interaction between the rotating reversing wheel 02 and the gear structure. Currently, the reversing wheel 02 and the reversing shaft 03 are directly connected via a key structure (single key or spline). This installation method is inconvenient due to the limited space at the installation location. While the interference fit between the reversing wheel 02 and the reversing shaft 03 provides high strength, the assembly process is quite difficult.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] To achieve the above objectives, this utility model provides a steering control device, including a reversing wheel rotatably mounted in a reversing chamber, reversing power cylinders located on both sides of the reversing wheel, and a reversing shaft connected to and driving the reversing wheel to rotate. The movable end of the reversing power cylinder is equipped with a rack structure that meshes with the reversing wheel; both rack structures mesh with the reversing wheel; wherein a first connecting plate is fixedly mounted on the end of the reversing wheel, and a second connecting plate is mounted on the output end of the reversing shaft; the first connecting plate and the second connecting plate are coaxially connected by fasteners.

[0007] According to the steering control device of this utility model, the output end of the reversing shaft is provided with a spline shaft, and the second connecting plate is provided with a keyway for inserting the spline shaft.

[0008] According to the steering control device of this utility model, the end of the first connecting disc is provided with a bushing structure, which is sleeved on the gear shaft; the first connecting disc is sleeved outside the gear shaft.

[0009] According to the steering control device of this utility model, positioning connection holes are provided at corresponding positions on the disk surfaces of the first connecting disk and the second connecting disk; a threaded connector for connecting the first connecting disk and the second connecting disk is installed in the positioning connection hole.

[0010] According to the steering control device of this utility model, the circumferential sidewalls and end face sidewalls of the first connecting plate and the second connecting plate are provided with slots for installing auxiliary positioning components; when the first connecting plate and the second connecting plate are assembled, they are assisted in positioning by the auxiliary positioning components.

[0012] This invention provides a steering control device, including a reversing wheel rotatably mounted in a reversing chamber, reversing power cylinders located on both sides of the reversing wheel, and a reversing shaft connected to and driving the reversing wheel to rotate.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0019] See Figure 1 , Figure 2 and Figure 3 This utility model provides a steering control device, which includes a reversing wheel 02 rotatably mounted in the reversing chamber, reversing power cylinders 01 located on both sides of the reversing wheel 02, and a reversing shaft 03 connected to and driving the reversing wheel 02 to rotate. Both ends of the reversing power cylinder 01 are provided with liquid outlets, forming a bidirectional hydraulic cylinder structure. The movable end of the reversing power cylinder 01 is equipped with a rack structure 1 that meshes with the reversing wheel 02, as shown in the figure. The rack structure 1 is disposed on the cylinder wall of the reversing power cylinder 01; both sets of rack structures 1 mesh with the reversing wheel 02.

[0020] During the reversing operation, the reversing wheel 02 is driven by the reversing shaft 03 to rotate in the forward or reverse direction, which further drives the reversing power cylinders 01 on both sides to operate in different states of hydraulic compression. This hydraulic fluid is then input into the power system to achieve different directions of rotation of the track drive wheel. The above part describes the steps for switching the rotation state of the track drive wheel, which is an existing structure and is only briefly described.

[0021] Regarding the assembly and fitting of the reversing wheel 02 and the reversing shaft 03, this application provides a first connecting plate 2 fixedly installed at the end of the reversing wheel 02, and a second connecting plate 3 installed at the output end of the reversing shaft 03; the first connecting plate 2 and the second connecting plate 3 are coaxially connected by fasteners. During installation, the first connecting plate 2 and the second connecting plate 3 are connected to the reversing wheel 02 and the reversing shaft 03 respectively, followed by assembly. Since the fitting strength of the first connecting plate 2 and the second connecting plate 3 is much lower than that of the reversing wheel 02 and the reversing shaft 03 (this is because in the original assembly process, the two need to be interference-fitted or overfitted, resulting in high assembly strength), the ease of assembly in confined spaces can be effectively increased.

[0022] The output end of the reversing shaft 03 is provided with a spline shaft 4, and the second connecting plate 3 is provided with a keyway for the spline shaft 4 to be inserted. The spline shaft 4 and the second connecting plate 3 are subjected to an interference fit or an overfit.

[0023] The first connecting disc 2 is provided with a bushing structure at its end, which is fitted onto the gear shaft 5; the first connecting disc 2 is fitted onto the gear shaft 5. Similarly, the bushing structure and the first connecting disc 2 are fitted with an interference fit or an overfit, and the bushing structure and the gear shaft 5 are connected by a bearing.

[0024] Positioning connection holes 6 are provided at corresponding positions on the first connecting plate 2 and the second connecting plate 3; a threaded connector for connecting the first connecting plate 2 and the second connecting plate 3 is installed in the positioning connection hole 6. The threaded connector can be a connecting bolt, which is screwed into the positioning connection hole 6.

[0025] See Figure 4 During assembly, after the first connecting disc 2 and the second connecting disc 3 are coaxially aligned, orientation and positioning are required to facilitate the connection of the threaded fasteners. To this end, the circumferential sidewalls and end face sidewalls of the first connecting disc 2 and the second connecting disc 3 are provided with slots 7 for installing auxiliary positioning components 8; during assembly, the first connecting disc 2 and the second connecting disc 3 are positioned using the auxiliary positioning components 8. The auxiliary positioning components 8 have a symmetrical double-sided "Γ" structure.

[0026] In summary, this utility model provides a steering control device, including a reversing wheel rotatably mounted in the reversing chamber, reversing power cylinders located on both sides of the reversing wheel, and a reversing shaft connected to and driving the reversing wheel to rotate. Both ends of the reversing power cylinder are provided with liquid outlets, forming a bidirectional hydraulic cylinder structure. The movable end of the reversing power cylinder is equipped with a rack structure that meshes with the reversing wheel, and the rack structure is disposed on the cylinder wall of the reversing power cylinder; both sets of rack structures mesh with the reversing wheel. During reversing operation, the reversing wheel is driven by the reversing shaft to rotate in either the forward or reverse direction, further driving the reversing power cylinders on both sides to experience different states of hydraulic compression, which is then input into the power system to achieve different directional rotation of the track drive wheel. This utility model can be assembled using the cooperation of a first connecting plate and a second connecting plate, reducing the assembly strength of traditional reversing wheels and reversing shafts, and effectively increasing the ease of assembly in confined spaces.

[0027] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
