VEHICLE WHEELED-WALKING PROPULSION UNIT Russian patent published in 2005 - IPC

FIELD: transport engineering; cross-country vehicles.

SUBSTANCE: proposed wheeled-walking propulsion unit has hollow housing with straight-line and curvilinear sections of surface which accommodates wheel whose axle is connected with vehicle engine. U-shaped bracket is mounted on bearings on wheel axle. Said bracket is stationary secured on vehicle. Two similar pressure rollers are installed in lower part of U-shaped bracket at both sides of wheel on axles of rotation. Said pressure rollers rest on connected walls following outline on hollow housing whose radii of curvatures of curvilinear sections exceed radius of wheel curvature. Curvilinear sections of outer surfaces of hollow housing feature lower coefficient of frictions as compared with straight-line sections.

EFFECT: provision of reliable pressing of main wheel to surface of hollow housing along which wheel is rolling.
