Abstract
A shift rod for the manual preselecting and shifting of transmission gears is constructed in two rod segments. The two rod segments are connected with one another by means of a vibration-damping coupling joint. The coupling joint is housed in a damping body that, in longitudinal direction of the shift rod, is developed to be softly resilient over a short distance, but with a subsequent strong spring progression, is developed to be very stiff with respect to torsion in twisting direction of the shift rod.
