Abstract
A pneumatic shifting force supporting device for a gearbox comprises a housing structure having a compressed air inlet and an air vent, and a control rod and an output unit comprising a working piston defining two pneumatic working chambers. A valve arrangement is functionally provided between control rod and output unit. By acting on the two pneumatic working chambers, the valve arrangement causes a pneumatic follow-up control from the output unit to the control rod comprising two valve pistons, annular sealing edges, valve spools and valve seats. A throttle slide is associated with at least one of the valve pistons and is slidable relative thereto. The throttle slide has a closing edge co-operating with the respective associated valve seat and delimiting at least one throttle passage, the cross-sectional area of which depends on the relative position of the throttle slide with respect to the associated valve piston.
