Wheeled Tractor Equipped with a Mechanism for Changing the Ground Clearance

EasyChair Preprint no. 4996

Abstract

In accordance with the agricultural cultivation practices adopted in the Central Asian region, machine-tractor units carry out a large number of passes through the field during the growing season. Consequently, individual sections of the fields are repeatedly affected by the running systems of these machines, which negatively affects soil fertility. The universal row-crop tractors used in cotton production have two types of wheel arrangements: 3W2 and 4W2.Consequently, these arrangements have a different nature and magnitude of impact on the soil. Despite a number of advantages of these 3-wheeled and 4-wheeled tractors due to insufficient agrotechnical clearance under the front axle beam, they are not used for inter-row cultivation of cotton crops. Mechanisms including a stepless change in ground clearance, both for the front and rear axles of a 4-wheeled tractor, eliminate these disadvantages and thereby expand the possibilities of their application.The use of a 4-wheeled tractor in field and transport operations has shown that the most loaded parts in the developed mechanism for changing the clearance of the rear axle are the rolling supports of the cage on the casing of the rear axle of the tractor. Studies have shown that parameters can be incorporated into the design of the parts of the mechanism for changing the clearance to ensure its reliable operation. Additionally, the calculated durability of the bearings 4074832 in accordance with GOST 4657-82 significantly exceeds the working life of the tractor, and this system, which includes the rolling bearings of the cage on the rear axle casing in the developed mechanism, is applicable for changing the clearance of the rear axle of the tractor.
