The present invention relates to a device for manual gearchange in a gearbox (2) in a vehicle with the assistance of a servo device. The device comprises a gear lever (1) and a motion-transmitting mechanism designed to transmit gearchange movements of the gear lever (1) to the gearbox (2), and a servo device comprising a pressure-medium-controlled power means (18) connected to the motion-transmitting mechanism, and a valve (22) which during the engagement and disengagement of a gear in the gearbox is designed to connect the power means (18) to a first pressure medium source so that the power means (18) provides auxiliary force to assist the gearchange movement. The device comprises a damper (42) which is connected to the motion-transmitting mechanism. The damper (42) is designed to damp the auxiliary force supplied by the power means (18) so that the auxiliary force is exerted more slowly but at a force which is required for executing the gearchange movement. |
