In a gearshift device for a semiautomatically shiftable change-speed gearbox of a motor vehicle, comprising a driver-operated clutch and a gearshift lever, movable only in a single shift lane, by means of which various shifter forks which are operable through an electromagnetically actuatable preselector device and act on synchronizers in the change-speed gearbox can be actuated. The gearshift lever is in the form of a tilting gearshift lever which always returns to its starting position; the shifting movement of the gearshift lever can be transferred by way of a gearshift linkage or a gearshift cable to a shifter slide (3) which is guided linearly in the direction transverse to a shifter shaft (1) of the change-speed gearbox; and the shifter slide (3), guided by means of upper and lower guide rails (4 and 5), cooperates with one of two transfer levers (9 and 11) by way of an upper or a lower pin-and-slot connection (22/21 and 19/18 respectively); and the shifter shaft (1) carries a fixed shifter hub (10) having a selector sleeve (17) fitted axially movably thereon which is slidable by means of an electromagnetically operable preselector device so as to come into driving connection with a clutch tooth system (14 and 15) on the respective transfer lever (9 and 11) and convert a tilting shift movement of the gearshift lever into one of two possible turning movements of the shifter shaft (1).

In a transmission with a countershaft and a planetary reduction gear unit, particularly for automobiles, having an input shaft (1) an output shaft (2), an intermediate shaft (23) fixed and loose pinions and gears which are in constant mesh alternately with one another and are releasably connectable to the shafts. The planetary reduction gear unit (28) comprises a ring gear (30) fixed against rotation, a sun wheel (33) driven by way of a set of pinions and gears and mounted on the intermediate shaft (23) and a planet carrier (32) connected to the output shaft. A member of a pinion-gear pair (16) is carried by the intermediate shaft (23) and is releasably connectable to the intermediate shaft (23) and the output shaft (2).

A device for changing the flow rate of a liquid damping medium is a torsional vibration damper. This damper has a rotating cylindrical damper housing, connected between a drive shaft and a power takeoff shaft. Pinions are surface-mounted in a planetary fashion without axle journals between the axial faceplates of a gear pump in recesses in the pump interior. The pinions are engaged with a central gear seated on the power takeoff shaft or on drive shaft, which form gear pumps for closed circulation of the damping medium.
