Abstract
A gear box actuator ( 100 ) for an automated manual transmission system ( 250 ) of a vehicle ( 200 a), in particular utility vehicle ( 200 b) includes a body part ( 105 ) and a shift fork ( 120 ) to actuate a gear box ( 260 ) of the automated manual transmission system ( 250 ) by pivoting the shift fork ( 120 ). The body part ( 105 ) includes a pivot section ( 130 ) for providing a fixed pivot point ( 131 ) for pivotally mounting the shift fork ( 120 ). The shift fork ( 120 ) includes a bearing surface ( 125 ), and the bearing surface ( 125 ) of the shift fork ( 120 ) and the pivot section ( 130 ) of the body part ( 105 ) are adapted to provide a sliding contact between each other for pivoting the shift fork ( 120 ) relative to the body part ( 105 ).
