MOBILE POWER UNIT Russian patent published in 2018 - IPC B62D55/04 B62D49/00 

FIELD: power engineering; transportation.

SUBSTANCE: invention relates to transmission of a mobile power unit (MPU). MPU contains an articulated support frame, motor unit, chassis comprising three bridges with a stepless hydraulic drive and wheeled or tracked running gear, two unified independent hinged systems, two unified independent PTO and ergonomic operator's cab. In this case, all three bridges are leading, each of them is connected to the supporting frame by means of independent flexible spring suspension systems. Same rotation frequency of the traction elements of the running gear in all operating conditions of MPU is provided by a special control system with a common regulator. When using tracked running gears that can be installed on both the front and rear sections of the frame, each contains one or two identical sprockets connected through the semi-axles with the corresponding differentials, support rollers and two or one tensioning roller. Support rollers are fixed in pairs on the walking beam suspensions and mounted on a tracked running gear in one row with a constant pitch of 0.5a (where a is the distance between the axes of the support rollers of one walking beam suspension, m), and adjacent walking beam suspensions are located on different sides of the support rollers row.

EFFECT: simpler layout and design of MPU, reduced compaction effect on the soil, higher adhesion are achieved.
