[0002] A tractor unit is a large truck or semi-trailer whose cab and trailer are towed by a tool. In other words, the cab can detach from its original trailer and tow other trailers, and the trailer can also detach from its original cab and be towed by other cabs. The cab with driving capability in front is called the tractor unit, and the trailer without driving capability behind it is called the trailer. The trailer is towed by the tractor unit.
[0003] Current tractor units generate centrifugal force when turning. At higher speeds, this centrifugal force can easily affect the tractor unit and even cause it to overturn on the traction side, increasing safety hazards. To address this, we have proposed a steering buffer mechanism for tractor units. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steering buffer mechanism for a tractor, comprising a mounting box, wherein a slot is provided in the center of the bottom of the mounting box, and a rotating shaft is symmetrically rotatably connected between the front and rear sides of the slot, and a first buffer assembly is provided inside the mounting box;
[0006] Connecting seats are fixedly connected to the left and right sides of the bottom of the mounting box. Rotating grooves are provided on the left and right sides of the first buffer component. A second buffer component is provided between the connecting seats and the rotating grooves.
[0007] As a further description of the above technical solution:
[0008] The first buffer assembly includes a deflecting rod, a slide groove, a rotating seat, a connecting plate, a counterweight, a connecting shaft, a sliding rod, a fixed plate, and a counterweight.

The bottom end of the deflecting rod is rotatably connected to the rotating seat. The bottom of the rotating seat is fixedly connected to the connecting plate. The bottom center of the connecting plate is fixedly connected to the counterweight. The connecting shaft is slidably connected inside the slide groove. Sliding rods are symmetrically fixedly connected to the outer side wall of the connecting shaft. Fixed plates are fixedly connected to the mutually distant ends of the left and right sliding rods. Counterweights are fixedly connected to the middle of the mutually distant sides of the left and right fixed plates.
[0009] As a further description of the above technical solution:
[0010] The sliding rod on the left side passes through the left side of the mounting box, and the sliding rod on the right side passes through the right side of the mounting box. Rotation grooves are provided in the middle of the left and right sides of the connecting plate.
[0011] As a further description of the above technical solution:
[0012] The second buffer assembly includes a first rotating block, a first mounting plate, a limiting rod, a second mounting plate, a second rotating block, a buffer spring, and a damper.

[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] The steering buffer mechanism of this tractor unit, through the setting of slots, shafts and first buffer components, causes the counterweight to deflect due to the centrifugal force generated when the tractor unit turns. By setting the deflection rod, the sliding rods on the left and right sides are opposite to the deflection direction of the counterweight, and the counterweight moves in the opposite direction to the counterweight. This changes the center of gravity of the device, reduces the centrifugal force generated, buffers the centrifugal force generated during steering, and prevents the tractor unit from overturning.
[0019] The steering buffer mechanism of this tractor unit, through the setting of the second buffer component, drives the connecting plate to move when the counterweight deflects, thereby causing the first rotating block and the second rotating block to deflect. This causes the second mounting plate to slide outside the limit rod, causing the buffer spring to deform and buffer the force generated by steering. With the cooperation of the damper, the force generated by steering is absorbed, making the device stable. In conjunction with the first buffer component, the force generated by steering is fully absorbed and buffered, improving the buffering effect and preventing the tractor unit from overturning.

[0028] This utility model provides a steering buffer mechanism for a tractor unit, which changes the center of gravity of the device, reduces the centrifugal force generated, and buffers the centrifugal force generated during steering, thus preventing the tractor unit from overturning. Please refer to [link / reference]. Figure 1-4 This includes the installation box 100;
[0029] Please refer to it again. Figure 2 The bottom center of the mounting box 100 has a slot 200, and the front and rear sides of the slot 200 are symmetrically connected by a rotating shaft 290. The inside of the mounting box 100 is provided with a first buffer assembly.
[0030] Please refer to it again. Figure 1 The bottom left and right sides of the mounting box 100 are fixedly connected to the connecting seats 300, the left and right sides of the first buffer component are provided with rotating grooves 380, and the connecting seats 300 and rotating grooves 380 are provided with a second buffer component.
[0031] Please refer to it again. Figure 2 The first buffer assembly includes a deflection rod 210, a slide 211, a rotating seat 220, a connecting plate 230, a counterweight 240, a connecting shaft 250, a sliding rod 260, a fixing plate 270, and a counterweight block 280.
[0032] Please refer to it again. Figure 2 A deflection rod 210 is fixedly connected to the middle of the outer side wall of the rotating shaft 290. A sliding groove 211 is opened through the top of the front side of the deflection rod 210. A rotating seat 220 is rotatably connected to the bottom end of the deflection rod 210. A connecting plate 230 is fixedly connected to the bottom of the rotating seat 220. A counterweight 240 is fixedly connected to the middle of the bottom of the connecting plate 230.
[0033] Please refer to it again. Figure 2 The sliding groove 211 is internally connected to a connecting shaft 250. The outer side wall of the connecting shaft 250 is symmetrically fixedly connected to a sliding rod 260. The opposite ends of the left and right sliding rods 260 are fixedly connected to a fixing plate 270. The middle part of the opposite sides of the fixing plate 270 is fixedly connected to a counterweight block 280.
[0034] In summary, by setting up the slot 200, the rotating shaft 290 and the first buffer assembly, when the tractor turns, the centrifugal force generated causes the weight 240 to deflect. By setting up the deflection rod 210, the sliding rods 260 on the left and right sides are deflected in the opposite direction to the weight 240, and the counterweight 280 moves in the opposite direction to the weight 240. This changes the center of gravity of the device, reduces the centrifugal force generated, buffers the centrifugal force generated during turning, and prevents the tractor from overturning.
[0035] Please refer to it again. Figure 2 The left sliding rod 260 passes through the left side of the mounting box 100, and the right sliding rod 260 passes through the right side of the mounting box 100. The connecting plate 230 has a rotating groove 380 in the middle of the left and right sides.
[0036] Please refer to it again. Figure 3 The second buffer assembly includes a first rotating block 310, a first mounting plate 320, a limiting rod 330, a second mounting plate 340, a second rotating block 350, a buffer spring 360, and a damper 370. The first rotating block 310 is rotatably connected inside the connecting seat 300. The first mounting plate 320 is fixedly connected to the bottom of the first rotating block 310. The limiting rod 330 is symmetrically fixedly connected to the bottom of the first mounting plate 320. The second mounting plate 340 is symmetrically slidably connected to the outer side wall of the limiting rod 330. The second rotating block 350 is fixedly connected to the bottom center of the second mounting plate 340. The buffer spring 360 is sleeved on the outer side wall of the limiting rod 330. The damper 370 is fixedly connected to the center between the opposite sides of the first mounting plate 320 and the second mounting plate 340.
[0037] Please refer to it again. Figure 3 The second rotating block 350 is rotatably connected to the inside of the rotating groove 380, and a baffle is fixedly connected to the bottom end of the limiting rod 330.
[0038] Please refer to it again. Figure 3 The two ends of the buffer spring 360 are fixedly connected to the opposite sides of the first mounting plate 320 and the second mounting plate 340, respectively.
[0039] In summary, by setting up the second buffer component, when the counterweight 240 deflects, it drives the connecting plate 230 to move, thereby causing the first rotating block 310 and the second rotating block 350 to deflect. This causes the second mounting plate 340 to slide outside the limit rod 330, causing the buffer spring 360 to deform and buffer the force generated by steering. With the cooperation of the damper 370, the force generated by steering is absorbed, making the device stable. In conjunction with the first buffer component, the force generated by steering is fully absorbed and buffered, improving the buffering effect and preventing the tractor from overturning.
[0040] In practical use, those skilled in the art install the device on a tractor, keeping the weight 240 vertical. When the tractor turns, the resulting centrifugal force causes the weight 240 to swing, moving the connecting plate 230 and the rotating seat 220. This causes the deflection rod 210 to deflect around the rotating shaft 290, pulling the connecting shaft 250 with the slide groove 211. This causes the sliding rod 260 to move in the opposite direction of the weight 240's swing, thus making the counterweight 280 swing in the opposite direction to the weight 240, thereby changing the device's center of gravity. The device's center of gravity is shifted inwards towards the direction of steering, and the counterweight 280 and the hammer 240 move in opposite directions to partially offset the centrifugal force generated. Furthermore, when the connecting plate 230 moves, the first rotating block 310 and the second rotating block 350 deflect, causing the second mounting plate 340 to slide outside the limit rod 330. This causes the buffer spring 360 to deform, buffering the force generated during steering. With the cooperation of the damper 370, the force generated during steering is absorbed, further buffering the centrifugal force during steering and ensuring steering stability.
