Electro-hydraulic system for the operation of multiple clutches and gear actuators with high-precision control of several manual transmission units simultaneously

摘要

A shift gearbox, a control unit, and at least one electric motor-driven driven piston-cylinder unit with a piston, which delimits at least one working chamber, which is connected via hydraulic lines to multiple shift gearbox units of the shift gearbox and shifts these, wherein the shift gearbox units comprise at least one gear selector unit and at least one clutch units, characterised in that the control unit for shifting at least one of the shift gearbox units rotates the electric motor drive by a predetermined angle and the piston of the piston-cylinder unit is adjusted by a predetermined path (Δs) (path control) and the piston thereby conveys a required hydraulic volume to or from at least one shift gearbox unit.
