VEHICLE WHEEL Russian patent published in 2016 - IPC B60C17/00 B60C5/20 

FIELD: machine building.

SUBSTANCE: present invention relates to wheels with pneumatic tires intended for wheeled vehicles including tractors, harvesters, excavators and other vehicles with springless suspensions. Wheel for transport applications contains a rim (1) and a pneumatic tire (2) mounted on it. Rim (1) has a built-in chamber (3) in the form of a continuous circular ledge at the outer contour. Built-in chamber (3) and tire cavity (2) are connected to each other through more than one valve-and-throttle assembly (4) located on the rim (1) inside the chamber (3). Valve-and-throttle units (4) are spaced from each other at the same distances along the circumference of the rim (1). Each valve-and-throttle assembly (4) has at least one valve and one orifice. There are filters to avoid clogging of the orifices and valve.

EFFECT: proposed wheel design ensures a uniform distribution of the mass throughout the entire volume of the wheel, which considerably reduces the dynamic unbalance of the wheel, increases the durability of rolling bearings used in the undercarriage, while maintaining the high anti-vibration properties of the wheel.
