[0031] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1-6 As shown, this utility model embodiment provides a tractor vehicle, which includes a loader 1 and a cargo box 2. The cargo box 2 uses the loader 1 as a tow vehicle to realize the transportation of goods. Moreover, the loader 1 as a tow vehicle can also solve the technical problem of the inflexible steering of ordinary tractor vehicles.

[0036] The loader 1 includes a frame 11, a connecting seat 12, and a steering drive component 13. The connecting seat 12 includes a main articulation body 121 and a first steering support 122. The main articulation body 121 is hinged to the frame 11, and the first steering support 122 is located on the side of the main articulation body 121 away from the frame 11. The truck body 2 is fixedly connected to the side of the main articulation body 121 away from the frame 11, and a clearance groove is provided at the end of the truck body 2 connected to the main articulation body 121. The first steering support 122 extends into the clearance groove. By setting the connecting seat 12 as the main articulation body 121 and the first steering support 122 connected to each other, the first steering support 122 can extend into the clearance groove of the truck body 2 when the truck body 2 is connected to the main articulation body 121, thereby reducing the overall length of the tractor and improving the flexibility of the whole vehicle.

[0037] Furthermore, one end of the steering drive component 13 is hinged to the first steering support 122, and the other end is hinged to the frame 11. The steering drive component 13 can drive the frame 11 to swing relative to the main articulation body 121, so that when the tractor is moving, the steering drive component 13 drives the frame 11 to swing left and right, so that the loader 1 swings left and right relative to the truck body 2, that is, the tractor can turn. Compared with the steering structure used in existing tractors, the turning radius is reduced and the steering flexibility is improved.

[0038] The tractor is hinged to the main articulation 121 of the frame 11 and the connecting seat 12. The steering drive 13 drives the frame 11 to swing relative to the main articulation 121 to achieve steering of the tractor, effectively improving steering flexibility. The connecting seat 12 is configured as the main articulation 121 and the first steering support 122. The first steering support 122 is located on the side of the main articulation 121 away from the frame 11. When the main articulation 121 is connected to the vehicle body 2, the first steering support 122 extends into the clearance groove of the vehicle body 2, which can reduce the overall length of the tractor and improve the overall vehicle flexibility.

[0039] Optionally, such as Figures 3-4 As shown, the frame 11 is provided with two first hinge seats 111 spaced apart in the vertical direction. The main hinge body 121 includes a main upright plate 1211 and two second hinge seats 1212 spaced apart in the vertical direction. The two first hinge seats 111 are respectively hinged to the two second hinge seats 1212. The main upright plate 1211 is provided with a clearance through-hole 1211a. The first steering support 122 is provided on the side of the main upright plate 1211 away from the frame 11. One end of the steering drive member 13 is hinged to the first steering support 122 through the clearance through-hole 1211a. This structure, by providing a clearance through-hole 1211a in the main upright plate 1211, allows the steering drive member 13 to be hinged to the first steering support 122 through the main upright plate 1211, making the structure more compact.

[0040] In this embodiment, each first hinge seat 111 includes a first hinge plate, and each second hinge seat 1212 includes two second hinge plates spaced apart in the vertical direction. The first hinge plates are disposed between the corresponding two second hinge plates and are hinged together by hinge pins.

[0041] Optionally, such as Figure 5 As shown, the first steering support 122 includes a U-shaped body, a first steering pin 1225, and steering connecting plates 1221 disposed at both ends of the U-shaped body (the U-shaped body and the steering connecting plates 1221 can be welded). By setting the U-shaped body, the steering connecting plates 1221 and the main upright plate 1211 can be parallel to each other, thereby making the steering connecting plates 1221 and the main upright plate 1211 fit together and connect (the steering connecting plates 1221 and the main upright plate 1211 can be connected by bolts), improving the connection firmness. One end of the steering drive component 13 is hinged to the U-shaped body through the first steering pin 1225, and the structural design layout is reasonable.

[0042] Furthermore, the U-shaped body includes two U-shaped plates 1222 spaced apart in the vertical direction. The ends of the two U-shaped plates 1222 are fixedly connected (welded) to the corresponding steering connecting plates 1221. One end of the steering drive member 13 is disposed between the two U-shaped plates 1222. The first steering pin 1225 passes through one U-shaped plate 1222, one end of the steering drive member 13 and the other U-shaped plate 1222 in sequence. This structure allows the steering drive member 13 to be hinged to the U-shaped body, enabling the steering drive member 13 to rotate around the first steering pin 1225.

[0043] Optionally, the U-shaped body also includes a first reinforcing plate 1223 disposed between the two U-shaped plates 1222. Three first reinforcing plates 1223 are provided, one of which is disposed in the middle of the U-shaped body, and the other two are disposed on both sides of the U-shaped body. The first reinforcing plates 1223 located on both sides of the U-shaped body are simultaneously welded to the U-shaped plates 1222 and the turning connecting plate 1221. This structure effectively improves the structural strength of the U-shaped body.

[0044] To ensure that the first steering pin 1225 does not rotate, optionally, such as Figure 5 and combined Figure 3As shown, a first limiting post 1224 is provided on a U-shaped plate 1222; the first steering pin 1225 includes a first pin plate and a first pin shaft vertically disposed on the first pin plate. The first pin plate is provided with a first limiting hole. When installing the first steering pin 1225, the first pin shaft passes through one U-shaped plate 1222, one end of the steering drive component 13, and another U-shaped plate 1222 in sequence. The first pin plate abuts against the U-shaped plate 1222 provided with the first limiting post 1224, and the first limiting post 1224 is inserted into the first limiting hole. This structure, by providing the first limiting post 1224 and the first limiting hole, enables the first steering pin 1225 to be positioned during installation and effectively prevents it from rotating on its own, avoiding wear and improving the service life of the first steering pin 1225.

[0045] Optionally, the steering drive component 13 can be selected as a hydraulic cylinder or an electric cylinder, and two steering drive components 13 are provided, which are distributed at intervals along the left-right direction of the loader 1. The two steering drive components 13 are located on both sides of the hinge position of the frame 11 and the main articulation body 121. Two second steering pins 1124 are provided on the U-shaped body to connect one end of each of the two steering drive components 13 to the U-shaped body. By providing two steering drive components 13, when the tractor turns, the drive shaft of one steering drive component 13 extends while the drive shaft of the other steering drive component 13 retracts, making the steering smoother.

[0046] Optionally, such as Figure 3 and Figure 6 As shown, the frame 11 is provided with a second steering support 112 that is hinged to the other end of the steering drive member 13. Two second steering supports 112 can be provided and are symmetrically distributed. The other ends of the two steering drive members 13 are respectively hinged to the two second steering supports 112. Specifically, the second steering support 112 includes a second steering pin 1124 and a steering body. The other end of the steering drive member 13 is hinged to the steering body through the second steering pin 1124. This structure realizes that the other end of the steering drive member 13 is hinged to the frame 11.

[0047] More specifically, the steering body includes two fixed plates 1121 spaced apart in the vertical direction. The other end of the steering drive member 13 is disposed between the two corresponding fixed plates 1121. The second steering pin 1124 passes through one fixed plate 1121, the other end of the steering drive member 13, and the other fixed plate 1121 in sequence, so as to achieve a hinge connection between the other end of the steering drive member 13 and the second steering support 112. In order to improve the structural strength of the steering body, the steering body also includes a second reinforcing plate 1122 (weldable) disposed between the two fixed plates 1121.

[0048] Specifically, a second limiting post 1123 is provided on a fixed plate 1121 of the steering body; the second steering pin 1124 includes a second pin plate and a second pin shaft vertically disposed on the second pin plate. The second pin plate is provided with a second limiting hole. The second pin shaft passes through a fixed plate 1121, the other end of the steering drive component 13, and another fixed plate 1121 in sequence. The second limiting post 1123 is inserted into the second limiting hole. This structure, by providing the second limiting post 1123 and the second limiting hole, enables the second steering pin 1124 to be positioned during installation and effectively prevents it from rotating on its own, avoiding wear and improving the service life of the second steering pin 1124.

[0049] Optionally, refer to Figure 1 As shown, the loader 1 also includes a travel motor 14 and a power battery 15. The travel motor 14 is used to drive the travel system of the loader 1, and the power battery 15 is used to provide electrical energy to the travel motor 14. By adopting electric drive technology and configuring the power battery 15, the emission pollution problem of fuel-powered tractors is solved.

[0050] Optionally, the loader 1 also includes counterweights 16 disposed on the left and right sides of the frame 11 to make the weight of the whole vehicle evenly distributed.

[0051] The tractor unit utilizes a novel structure for the loader 1 and the tractor box 2, resulting in a reasonable and compact overall layout. The articulation between the connecting seat 12 and the frame 11 solves the problem of inflexible steering, improves the reliability and flexibility of the tractor unit, and reduces costs. Furthermore, the adoption of electronic control technology for the walking motor 14 and the power battery 15 solves the pollution problem.
