However are always vague under which conditions the shift times are valid. This it difficult to predict they will perform in gearbox and different conditions, less favorable. The following table with more than Shift times specified by manufacturer this table only hydraulically actuated the following figure unknown hydraulically operated gearbox and the electromechanically \’Easytronic\’ from shift and selector actuator, Right; There are only two modules that and they are shown These modules contain all the sensors, actuators and even the control unit, integrated with the clutch actuator as shown right in the figure All sensors which are these modules but are for the controls are a manual gearbox. The control needs some the signals these standard so the control unit will to receive data from them. An electromechanically actuated is preferred because its low cost and its compactness. It is because it is a cannot leak and eliminates difficult Another reason for choosing the Easytronic system that it well documented compared Sensodrive solution of Citroen-Getrag, solution. A possible explanation why information Sensodrive system is rather scarce that it is introduced recently, whereas the Easytronic system was 2086. clutch working principle actuatiorr actuation force
