POWER MODULE Russian patent published in 2000 - IPC

FIELD: transport engineering; base chassis with hydrostatic transmission. SUBSTANCE: module is designed for use with different road-building and agricultural equipment. Power module has power plant with variable-capacity pumps to drive technological equipment and travel motion gear. Pressure pipeline of travel motion gear drive pumps are interconnected by two-position distributors and are connected with pressure pipelines of technological equipment pumps by three-position distributors. Power plant has also control units connected with variable-capacity pumps, final drives with travel motion drive hydraulic motors, hitch gear with support wheel and steering hydraulic cylinders and turning bracket with driver's seat. Travel motion drive pumps are reversible. Pressure and drain channels of distributors are combined in pairs by pipelines, drain pipeline being furnished with overflow valve. Purpose of invention is regulation of movement of driver in response to direction of movement of module and prevention of peak pressures in hydraulic system of travel motion drive by excluding distributors reversing rotation of hydraulic motors. EFFECT: enhanced reliability of operation. 5 cl, 6 dwg
