CONSTRUCTION OF SUSPENSION FOR REAR SELF-CENTERING WHEELS ON WORKING MACHINE Russian patent published in 2014 - IPC A01D75/00 B60G5/00 B60G3/00 

FIELD: agriculture.

SUBSTANCE: working machine comprises a frame, at least one drive wheel mounted on the frame, at least one rear axle rigidly secured to the frame, and substantially fixed relative to it, at least one node of the self-centering wheel which comprises a shaft, a wheel lever, a suspension and a self-centering wheel. The shaft is pivotally connected to the outer end of the rear axle, the suspension is connected to the wheel lever and the shaft so as it is turned to them, and the self-centering wheel is connected to the lower end of the wheel lever and is made with the ability to rotate in more than one direction. The suspension of the working machine comprises a frame and the rear axle rigidly attached to the frame and fixed relative to it, the node of the self-centering wheel which comprises the shaft, the wheel lever, the suspension and the self-centering wheel. The shaft is made with the ability of articulated joint with the outer end of the rear axle, and the self-centering wheel is connected to the lower end of the wheel lever. The suspension is a torsion spring which comprises an outer tube, an inner element and elastomeric elements. The outer tube is connected to the shaft, and the inner element is connected to the upper end of the wheel lever, so that the suspension is turned to the shaft and the wheel lever, and the wheel lever is suspended flexibly relative to the shaft and is made with the ability to turn in more than one direction.

EFFECT: use of the group of inventions provides smooth driving and sufficient clearance between the ground and the machine.
