[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] Please refer to Figure 1-Figure 5 The utility model discloses a sway-stopping mechanism for a driving wheel 100 of a forklift. The forklift includes a mounting frame 200 for mounting the driving wheel 100. The mounting frame 200 is clearance-matched with a frame 300 of the forklift. The driving wheel sway-stopping mechanism includes:

[0031] an adjustment frame 400 fixed to the vehicle frame 300;

[0032] an adjusting screw 410 threadedly connected to the adjusting frame 400 , wherein one end of the adjusting screw 410 can pass through the adjusting frame 400 and abut against the mounting frame 200 ;

[0033] The adjusting frame 400 and the mounting frame 200 are arranged along the driving direction of the forklift, so that the adjusting screw 410 applies a pre-tightening force along the driving direction to the mounting frame 200 .

[0034] Specifically, the present application provides an adjustment frame 400 on the vehicle frame 300, and an adjustment screw 410 is threaded through the adjustment frame 400. By rotating the adjustment screw 410, the adjustment screw 410 slides toward or away from the mounting frame 200, so that the adjustment screw 410 can abut against the mounting frame 200, thereby driving the mounting frame 200 to abut against the vehicle frame 300, so as to eliminate the gap between the mounting frame 200 and the vehicle frame 300, thereby preventing the drive wheel 100 from swinging back and forth during driving.

[0035] The driving direction refers to the forward or backward direction of the forklift. When the adjusting screw 410 applies a force along the front-to-back direction to the mounting frame 200, the front end or rear end of the mounting frame 200 will abut against the frame 300, thereby eliminating the gap between the mounting frame 200 and the frame 300 in the front-to-back direction, ensuring that the drive wheel 100 does not swing back and forth during driving.

[0036] Furthermore, the adjustment frame 400 is located behind the mounting frame 200 .

[0037] Specifically, the adjustment frame 400 is located behind the mounting frame 200, and the direction of the force exerted by the adjustment screw 410 on the mounting frame 200 is toward the front of the vehicle, so that the front end of the mounting frame 200 is against the frame 300, eliminating the gap between the front end of the mounting frame 200 and the frame 300, and preventing the driving wheel 100 from swinging back and forth.

[0038] Furthermore, one end of the adjusting screw 410 facing the mounting frame 200 is connected to a bottom plate 420 , and the bottom plate 420 is slidably connected to the adjusting frame 400 .

[0039] Specifically, the base plate 420 is provided to increase the contact area between the base plate 420 and the mounting frame 200, thereby increasing the force exerted by the adjusting screw 410 on the mounting frame 200, so that the mounting frame 200 can be more closely abutted against the vehicle frame 300, thereby improving the stability of the driving wheel 100 during driving.

[0040] Furthermore, a guide post 421 is provided on the bottom plate 420 , and a guide hole 401 is opened on the adjustment frame 400 . The guide post 421 can extend into the guide hole 401 and slide along the guide hole 401 .

[0041] The guide posts 421 and the guide holes 401 are provided to guide the sliding direction of the bottom plate 420 , so as to facilitate the bottom plate 420 to fit the surface of the mounting bracket 200 .

[0042] Furthermore, the adjusting screw 410 is located in the middle of the bottom plate 420;

[0043] Two guide posts 421 are provided on the bottom plate 420 , and the two guide posts 421 are symmetrical with respect to the adjusting screw 410 .

[0044] Specifically, the adjusting screw 410 is located in the middle of the bottom plate 420, so that the force on the left and right sides and the upper and lower ends of the bottom plate 420 is more uniform, and the bottom plate 420 is not easy to tilt left and right or up and down when subjected to force.

[0045] The two guide posts 421 are symmetrical about the adjusting screw 410 , so that the two guide posts 421 are symmetrical about the center of the bottom plate 420 , so that the forces on the two guide posts 421 are more uniform.

[0046] Furthermore, an abutting plate 430 is provided between the bottom plate 420 and the mounting frame 200 . One side of the abutting plate 430 can abut against the bottom plate 420 , and the other side of the abutting plate 430 can abut against the mounting frame 200 .

[0047] Specifically, the contact plate 430 is provided to contact the bottom plate 420 to prevent the surface of the mounting frame 200 from directly contacting the bottom plate 420 , thereby protecting the surface of the mounting frame 200 from being scratched or impacted by the bottom plate 420 , thereby protecting the mounting frame 200 .

[0048] Furthermore, the area of ​​the abutting plate 430 is larger than the area of ​​the bottom plate 420 .

[0049] The area of ​​the abutting plate 430 is larger than that of the bottom plate 420 , which can further increase the contact area between the abutting plate 430 and the mounting bracket 200 , so that the mounting bracket 200 and the vehicle frame 300 can be more closely abutted.

[0050] Furthermore, the abutting plate 430 is fixedly connected to the mounting frame 200 or the bottom plate 420 .

[0051] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0052] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0053] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0054] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
