METHOD OF PULLING AND COUPLING PROPERTIES IMPROVEMENT IN PROPELLING DEVICE AND ASSOCIATED DEVICE

摘要

FIELD: agriculture. ^ SUBSTANCE: invention relates to vehicles, used mainly for agricultural works. The method includes application of additional supports by inserting them into the more compact layer of subsurface soil in closed state. Then supports are opened extending thereby the area of contact and reducing pressure of the wheeled propelling device tires to the top layers of soil. The associated device consists of an axle fixed in the wheel crown disc. The above axle fixes position of the guiding bracket. There is a movable rack inside the above guiding bracket. The device is also provided with jaw having ellipse-shaped working surface. The jaw is installed on a fixed axle so that it can rotate. Besides, the rotation axis is shifted from ellipse symmetry axis by the value of rack advancing. There is a support with triangle-shaped working surface in the lower part of the rack. The support is hinge installed on its axis. There is a roller in the upper part of the rack. The roller can roll over the above jaw surface. ^ EFFECT: improved functional properties of propelling device due to reduction of adverse effect to ground and improvement of pulling and coupling properties of vehicle wheel. ^ 2 cl, 4 dwg
