WHEEL-WALKING CHASSIS Russian patent published in 2024 - IPC A61G5/06 B62D57/28 

FIELD: off-road vehicles.

SUBSTANCE: invention can be used as a chassis for wheelchairs. The wheel-walking chassis consists of three satellite rollers driven by a central wheel. The pneumatic central wheel for movement in wheeled mode has three levers with satellite rollers at the ends of the levers in the upper part of the pneumatic wheel, which are equipped with mechanisms for rotating the levers around the axis of rotation of the central wheel and fixing them relative to each other through 120°, providing frictional connection of satellite rollers with the central wheel for movement in wheel-walking mode.

EFFECT: simplification and unification of the technology for manufacturing wheelchair chassis for overcoming obstacles.
