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

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine building and may be used, in particular, to perform works at relatively small (country and/or farming) sections of mainly flat type. Agriculture bridge two-wheeled comprises two wheels with individual drive wheel rim part, stators of which are connected with unified beam-chassis for replaceable working elements. Each hubless wheel design in the form of rim with pneumatic tyre has two adjoining wheel triangular frames connected by three pairs of shafts. On internal with respect to rim with pneumatic tyre shafts are mounted roller supports under the rim. On external with respect to rim with pneumatic tyre shafts are mounted close to the friction rollers unicamerate hyperboloid shape under pneumatic tyre. Rim in symmetry with pneumatic tyre on external parts of lower additionally mounted support wheels or pulleys with covering tracks. At least one of three friction rollers close to unicamerate hyperboloid shape under pneumatic tyre serves drive rim with pneumatic tyre.

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