Полезная модель относится к машиностроению и может быть использована для изготовления поворотных шариковых кругов транспортных средств, погрузочной техники, строительного оборудования. За счет того, что плоскости сопряжения вертикальных стенок колец сверху и снизу от шарика смещены относительно друг друга в радиальной плоскости круга, при этом выносы образованы горизонтальными участками, а кромки скруглены, изнашиваемая поверхность шарика и поверхность канавки становится больше, в результате повышается равномерность износа и долговечность круга. За счет выполнения участка выноса горизонтальным достигается сохранение простоты изготовления канавок колец.

A work vehicle includes a frame assembly and an attachment assembly. The attachment assembly has an attachment end pivotally connected to the frame assembly and a distal end configured for receiving a variable load. At least one force sensor senses at least one force associated with the attachment end. The at least one force sensor provides an output signal representing the sensed at least one force. An inclination sensor senses an inclination associated with the frame assembly and provides an output signal representing the sensed inclination. An electrical processing circuit is configured for receiving the output signal from the at least one force sensor, determining a value of a couple at the frame assembly which is associated with the sensed at least one force, comparing the couple with a threshold value which is dependent on the sensed inclination, and controlling the controllable output dependent on the comparison. 1.
