Description

Technical Field

[0001] This utility model relates to the field of tractor technology, and in particular to a hinged tractor with a steering structure. Background Technology

[0002] A cantilever tractor is a tractor in which the front and rear axle assemblies can rotate. The front and rear axle assemblies are connected by a coupling, transmitting power from the engine to the two rear wheels to move the tractor. A shaft is also installed between the front and rear axle assemblies for their rotational connection. Hydraulic cylinders are mounted on both sides of the shaft, connected to the front and rear axle assemblies via connecting seats. When turning left, the piston rod of the left hydraulic cylinder shortens, while the piston rod of the right hydraulic cylinder extends, causing the rear axle assembly to rotate relative to the front axle assembly, thus turning left. When turning right, the piston rod of the right hydraulic cylinder shortens, while the piston rod of the left hydraulic cylinder extends, thus turning right.

[0003] In common articulated tractors with steering mechanisms, the hydraulic cylinders are connected to the front and rear axle assemblies via connecting seats. When the articulated tractor turns, the connection points between the connecting seats and the front and rear axle assemblies experience significant stress, and the contact areas at these points are relatively small. This makes these connections prone to cracking, which can affect the normal operation of the articulated tractor. Therefore, this application provides an articulated tractor with a steering mechanism to meet this requirement. Utility Model Content

Connecting seats one are fixed to both sides of the front axle assembly, and connecting seats two are fixed to both sides of the rear axle assembly. A hydraulic cylinder is disposed between connecting seats one and connecting seats two. The end of the hydraulic cylinder away from connecting seat two is rotatably connected to connecting seat one, and the telescopic end of the hydraulic cylinder is rotatably connected to connecting seat two. A square plate is fixed to the side of the front axle assembly, and a triangular plate is fixed to the side of the square plate. The sides of the square plate and the triangular plate are fixedly connected to the side of connecting seat one. An elongated groove is formed on the side of the square plate. A fixing block is fixed to the side of the rear axle assembly, and a connecting block is fixed to the side of the fixing block. The side of the connecting block is fixedly connected to the side of connecting seat two.

[0007] Preferably, a rhomboid strip is fixed to the side of the triangular plate away from the square plate, one end of the rhomboid strip is fixedly connected to the side of the connecting seat, and the other end of the rhomboid strip is fixedly connected to the side of the square plate.

[0008] Preferably, the thickness of the long right-angle side of the triangle is greater than the thickness of the hypotenuse.

[0009] Preferably, square grooves are formed on both opposite sides of the inner wall of the elongated groove.

[0010] Preferably, the central axis of the square groove is perpendicular to the central axis of the elongated groove.

[0011] Preferably, the square plate has notches on both opposite sides.

[0028] like Figures 1-4As shown, an embodiment of this utility model provides a folding tractor with a steering structure, including a tractor body (not shown in the figure). A front axle assembly 2 and a rear axle assembly 3 are respectively disposed at the bottom of the tractor body. The front axle assembly 2 and the rear axle assembly 3 together form the chassis of the tractor body. Front wheels are mounted on both sides of the front axle assembly 2, and rear wheels are mounted on both sides of the rear axle assembly. Brake assemblies are installed at both the front and rear wheels for braking. The front axle assembly 2 and the rear axle assembly 3 are connected by a coupling. A [missing information - likely a design feature] is provided between the front axle assembly 2 and the rear axle assembly 3. A pivot shaft 4 is provided for the rotatable connection between the front axle assembly 2 and the rear axle assembly 3. Connecting seats 1 and 2 are fixed on both sides of the front axle assembly 2, and connecting seats 2 and 3 are fixed on both sides of the rear axle assembly 3. A hydraulic cylinder 7 is installed between the connecting seats 1 and 2 and 6. The end of the hydraulic cylinder 7 furthest from the connecting seat 2 and 6 is rotatably connected to the connecting seat 1. A round shaft is fixed to the inner wall of the connecting seat 1. The round shaft is used for the rotatable connection between the cylinder end of the hydraulic cylinder 7 and the connecting seat 1. The telescopic end of the hydraulic cylinder 7 is rotatably connected to the connecting seat 2 and 6. This structure constitutes the steering structure. To enable steering of the articulated tractor, a square plate 8 is fixed to the side of the front axle assembly 2, and a triangular plate 9 is fixed to the side of the square plate 8. Both the sides of the square plate 8 and the triangular plate 9 are fixedly connected to the side of the connecting seat 5. The square plate 8 and the triangular plate 9 increase the contact area between the connecting seat 5 and the front axle assembly 2, thereby improving the connection strength between the connecting seat 5 and the front axle assembly 2 and preventing cracking at the connection point. A long groove 12 is provided on the side of the square plate 8, and welding is performed between the square plate 8 and the front axle assembly 2 within the side of the square plate 8 and the long groove 12. The long groove 12 enhances the steering capability of the square plate 8. The welding strength between plate 8 and front axle assembly 2 is improved. A fixing block 1 is fixed to the side of the rear axle assembly 3, and a connecting block 14 is fixed to the side of the fixing block 1. The side of the connecting block 14 is fixedly connected to the side of the connecting seat 2 6. The fixing block 1 is fixed to the rear axle assembly 3 by welding, and the connecting block 14 is fixed between the connecting seat 2 6 and the fixing block 1. The fixing block 1 increases the contact area between the connecting seat 2 6 and the rear axle assembly 3, improves the connection strength between the connecting seat 2 6 and the rear axle assembly 3, and prevents cracking at the connection position, so as not to affect the normal use of the articulated tractor.

[0029] like Figure 2 and Figure 3 As shown, in this embodiment, a rhomboid strip 10 is fixed on the side of the triangle 9 away from the square plate 8. One end of the rhomboid strip 10 is fixedly connected to the side of the connecting seat 5, and the other end of the rhomboid strip 10 is fixedly connected to the side of the square plate 8. The rhomboid strip 10 is used to increase the thickness of the side of the triangle 9 away from the square plate 8, prevent the triangle 9 from deforming, and thus improve the structural strength of the triangle 9.

[0030] like Figure 3As shown, in this embodiment, the thickness of the long right-angle side of the triangle 9 is greater than the thickness of the hypotenuse of the triangle 9, which further prevents the triangle 9 from deforming under force, thereby improving the connection strength between the square plate 8 and the connecting seat 5.

[0031] like Figure 2 and Figure 3 As shown, in this embodiment, square grooves 13 are provided on both sides of the inner wall of the elongated groove 12. Welding can be further performed in the square grooves 13 to further increase the contact area between the square plate 8 and the front axle assembly 2, thereby improving the connection strength between the square plate 8 and the front axle assembly 2.

[0032] like Figure 2 and Figure 3 As shown, in this embodiment, the central axis of the square groove 13 is perpendicular to the central axis of the elongated groove 12, and the square groove 13 is perpendicular to the elongated groove 12, thereby facilitating welding operations within the square groove 13 and the elongated groove 12.

[0033] like Figure 2 and Figure 3 As shown, in this embodiment, notches 11 are provided on both sides of the square plate 8. Welding is performed between the square plate 8 and the front axle assembly 2 on the inner side of the notch 11, thereby improving the connection strength between the square plate 8 and the front axle assembly 2.

[0034] like Figure 2 and Figure 3 As shown, in this embodiment, the notch 11 is semi-circular, and the semi-circular notch 11 facilitates welding operations within the notch 11.

[0035] like Figure 4 As shown, in this embodiment, the side of the fixing block 1 away from the connecting seat 6 is an inclined surface. The inclined surface is used to achieve stable support for the fixing block 1 and improve the connection tightness between the fixing block 1 and the rear axle assembly 3.

[0036] Working principle: When turning left, the left hydraulic cylinder 7 is activated, causing the piston rod of the left hydraulic cylinder 7 to shorten and the piston rod of the right hydraulic cylinder 7 to extend, driving the rear axle assembly 3 and the front axle assembly 2 to rotate around the pivot 4, thus realizing the left turn of the articulated tractor. When turning right, the piston rod of the right hydraulic cylinder 7 is shortened and the piston rod of the left hydraulic cylinder 7 to extend, driving the rear axle assembly 3 and the front axle assembly 2 to rotate in the opposite direction around the pivot 4, thus realizing the right turn of the articulated tractor.

[0037] The square plate 8 is fixed to the side of the front axle assembly 2 by welding. Then, welding is performed on the inner walls of the notch 11, the long groove 12, and the square groove 13 to further improve the connection strength between the square plate 8 and the front axle assembly 2. The left side of the square plate 8 is connected to the side of the connecting seat 1 5 by welding. The triangular plate 9 is used to connect and fix the square plate 8 and the connecting seat 1 5. The square plate 8 and the triangular plate 9 increase the contact area between the connecting seat 1 5 and the front axle assembly 2, prevent the connection position of the connecting seat 1 5 and the front axle assembly 2 from cracking, and improve the connection strength between the connecting seat 1 5 and the front axle assembly 2. The fixing block 1 is fixed to the rear axle assembly 3 by welding. The connecting block 14 is fixed between the connecting seat 2 6 and the fixing block 1 by welding. The fixing block 1 increases the contact area between the connecting seat 2 6 and the rear axle assembly 3, prevents the connection position of the connecting seat 2 6 and the rear axle assembly 3 from cracking, and improves the connection strength between the connecting seat 2 6 and the rear axle assembly 3.
