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

FIELD: transport machine building.

SUBSTANCE: invention relates to automotive industry, particularly, to wheelchair chassis. Wheelchair chassis consists of system of three onboard pneumatic low-pressure wheels arranged on ends of one of three radial brackets of assembly rotating on central axis, and wheel drive mechanism. Wheel drive mechanism is made according to planetary scheme. Central wheel is driving in planetary gear, and carrier is complementary, which is included in operation in obstacle overcoming mode with rotation in the same direction as geometrical axes of side wheels, and in braking mode with rotation against geometrical axes of side wheels.

EFFECT: higher cross-country capacity in all motion modes with overcoming obstacles, as well as higher safety of descent by stair flight of general use in wheel-walking mode.
