Shifting device for a variable speed motor vehicle transmission

摘要: The invention relates to a shifting device (11, 40) having servo-assistance (10), particularly for transmission (30) of motor vehicle, comprising means selecting and gear step the (30), an element (20), upon which assisting manual force acts. With (10) characteristic curve can be created, has, as function or phase, regions with different gradients proportionalities force. In order create curve, (88, 90, 106, 108) are provided in servo pressure A path limitation at least one resilient (84, 110) upstream and/or when actuating limit servo- assistance path-dependant manner each gate gear.
