The device (10) has a differential piston (42) and a spring (44) on which servo pressure is acted, where a characteristic curve is represented by the servo pressure. The characteristic curve has regions with different slopes and/or proportionalities for hand switching force, based on the hand switching force and/or circuit phase. The differential piston and spring are arranged in the servo assistance device such that a volatile reduction of servo assistance force is realized. A piston rod (22) cooperates with a unit for switching a gear wheel change speed gear. |
