TWO-WHEELED AGRICULTURAL BRIDGE Russian patent published in 2016 - IPC A01B49/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention can be used, in particular, to perform works at relatively small (country and/or farming) plots of land of mainly flat type. Two-wheeled agriculture bridge comprises two wheels with individual drive wheel rim part. Wheel stators are unified beam-chassis for replaceable working elements. Each hubless wheel design in the form of rim with pneumatic tyre has two adjacent to wheel triangular frames. At least one of the triangular frames, which is symmetric about the longitudinal plane of symmetry of the vertically oriented wheel represents a link mechanism, where two inner two-arm levers connected lower hinge at the level of wheel rotation axis, form a short arms hinged load-carrying Rhombus at cantilever end of beam-chassis, ending at long diagonal rollers. Rollers roll on external single-arm levers lockable into the frame by two pairs of shafts in each top frame: internal shafts under rollers for RIM, external shafts under the friction rollers close to unicameral hyperboloid shape for pneumotyre. At least one of three friction rollers is drive rim with pneumotyre. On external shafts at the bottom can be additionally mounted wheeled chassis, track or ski design.

EFFECT: such design allows simplifying and unifying the technology of making the agriculture bridge two-wheel.
