Technical Field

[0001] This utility model relates to the field of tractor technology, and in particular to a variable wheelbase front axle connection assembly and a front axle. Background Technology

[0002] Tractors are an important component of agricultural production equipment, capable of performing various operations such as plowing, rotary tilling, sowing, and spraying. To meet the needs of different agricultural operation scenarios, tractor wheelbases are set differently. For heavy-duty operations such as deep plowing and deep loosening, tractors with a long wheelbase are generally selected; while for environments with small operating sites and limited space, tractors with a short wheelbase are more suitable.

[0003] Currently, the front axle of tractors cannot be moved, which means the wheelbase cannot be shortened or changed, making it unsuitable for actual production needs. Therefore, there is an urgent need for a front axle connection assembly and front axle that can easily adjust the wheelbase. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a variable wheelbase front axle connection assembly and front axle that is simple in structure, low in cost, and easy to operate.

[0005] This utility model discloses a variable wheelbase front axle connection assembly, including a front axle located at the front end of a tractor, with two sets of connecting frames symmetrically mounted in its middle. The front axle is fixedly connected to the front axle seat and the oil pan respectively through the two sets of connecting frames.

[0006] A first screw hole is provided on the front axle seat, and a second screw hole is provided on the oil pan. The first screw hole and the second screw hole are respectively fixedly connected to the two connecting brackets by bolts. A corresponding third screw hole is provided on the connecting bracket.

[0007] The distance between the first screw hole and the second screw hole corresponds to the distance between the two connecting brackets, and at least one set of screw holes is provided, consisting of the first screw hole and the second screw hole.

[0008] This utility model discloses a variable wheelbase front axle connection assembly, wherein the variable wheelbase front axle connection assembly is arranged in the following order along the tractor from the tail to the head: oil pan, front axle seat, and front axle.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-6 Specifically, the following embodiments are included: Example 1:

[0035] Reference Figures 1-2 As shown, the arrangement of a variable wheelbase front axle connection assembly along the tractor from the rear to the front is as follows: oil pan 3, front axle seat 2, and front axle 1.

The first screw hole 20 and the second screw hole 30 are respectively fixedly connected to the two connecting brackets 10 by bolts. The support bracket 13 has a third screw hole 11.

[0038] The spacing between the first screw hole 20 and the second screw hole 30 corresponds to the spacing between the two connecting brackets 10. The first screw hole 20 and the second screw hole 30 are provided in two groups, with four screw holes in each group.

[0039] The number of support rods 21 and bosses 31 corresponds to the number of the first screw holes 20 and the second screw holes 30.

[0040] When changing the wheelbase during use, loosen the connecting bolts and move the entire front axle, along with its connecting bracket 10, to the new position along the longitudinal direction of the tractor. Align the third screw hole 11 on the connecting bracket 10 with another set of pre-set screw holes on the front axle seat 2 and the oil pan 3, namely the first screw hole 20 and the second screw hole 30. Then, retighten the bolts. Different screw hole positions correspond to different wheelbases.

[0041] This invention enables flexible adjustment of the wheelbase. By changing the installation position of the connecting frame 10 on different sets of screw holes on the front axle seat 2 and the oil pan 3, the longitudinal position of the front axle 1 relative to the tractor body can be easily changed, thereby realizing the adjustment of the tractor wheelbase. This solves the problem of the existing fixed front axle and unchangeable wheelbase, thus enabling the tractor to better adapt to the needs of different scenarios such as heavy-load operations such as deep plowing / deep loosening and flexible operations in small spaces. Example 2:

[0046] The number of support rods 21 and bosses 31 corresponds to the number of the first screw holes 20 and the second screw holes 30.

[0047] During use, the entire front axle 1, along with its connecting bracket 10, is lifted so that the third screw hole 11 on the connecting bracket 10 is aligned with the first screw hole 20 and the second screw hole 30 on the front axle seat 2 and the oil pan 3. Then the bolts are tightened to shorten the wheelbase.

[0048] This utility model enables the front axle 1 to connect to the front axle seat 2 and the oil pan 3 via the connecting frame 10, thus achieving a variable wheelbase. This replaces the traditional connecting frame 10, which can only be fixed on the front axle seat 2.
