Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a traction assembly and agricultural machinery. Background Art

[0002] In recent years, with the continuous development of economy and technology, various agricultural machinery, such as tractors, have been increasingly used in agricultural production activities.

[0003] There are many types of tractors with existing structures. Some are specifically used for farming, while others are specifically used for transportation. Tractors used for transportation usually include a front axle, a middle axle and a rear axle, and the carriages are set on the middle axle and the rear axle. When driving on uneven roads, if any wheel at either end of the middle axle or the rear axle is sunken, the other wheel will be suspended. Due to the influence of the differential, the middle axle or the rear axle where the suspended wheel is located will lose driving force, resulting in a decrease in the driving ability of the tractor and affected passability.

[0004] In summary, how to provide a traction assembly that can effectively improve the driving ability of agricultural machinery and make it have better passability, as well as agricultural machinery including this traction assembly, has become a technical problem that technical personnel in this field urgently need to solve.

The front wheel, the middle wheel and the rear wheel are all driving wheels. During operation, under the action of the traction assembly, the trailer 29 can swing left and right, and can also swing forward and backward. Even when traveling on a bumpy road, the two middle wheels and the two rear wheels are always in contact with the ground, thereby ensuring that the six wheels of the agricultural machinery can also be on the ground at the same time. Therefore, the driving ability is stronger and the passability is better.
