Dispositiva para o acionamento de uma arvore de mudança de velocidade giratoria por um eixo e deslocavel ao longo de eixo de uma caixa de cambio

摘要

The selector shaft can be swivelled about an axis and is displaceable along the axis. The device also contains a swivel actuator 26 for swivelling the selector shaft and a displacement actuator 24 for displacing the selector shaft. At least one of the two actuators 24,26 operates the selector shaft 2 by means of a component 12,14 which can be swivelled by the actuator about an axis AA which is locally fixed relative to a housing of the shift transmission. The component is in positive locking engagement with the selector shaft relative to the swivel or displacement movement of the selector shaft produced by the actuator, but is out of engagement relative to the displacement or swivel movement of the selector shaft.
