DECOUPLING DEVICE FOR GEARSHIFT LINKAGES Abstract of the Disclosure: The decoupling device is used for connecting the rods, especially gearshift rods disposed between the transmission and the gearshift lever of a motor vehicle. The incorporation of the device into the gearshift linkage permits to and fro movement of the decoupled gearshift rod and suspends the rigid connection between the gearshift lever and the transmission after the transmission has been shifted into a gear. A form-locking connection between the two gearshift rods is only established at the time of selecting or shifting in and out of a gear. The suspension of the rigid connection between the gearshift lever and the transmission effected by the decoupling device eliminates the problem of gear-jumping. The decoupling device incorporates a displaceable intermediate member adapted to control the decoupling operation, which is disposed between ends of the gearshift rods which are in engagement with one another and are located inside a tubular member. The intermediate member is supported on a blade disposed on one of the gear- shift rods and is provided with a decoupling element which is cooperating with depressions in the blade and/or the channel of the gearshift rod for establishing a form-locking connection. Furthermore, the intermediate member is provided with locking means which engage with depressions (Abstract -- Continued) provided in the tubular member surrounding the ends of the gearshift rods. It is also possible to provide coupling between the two gearshift rods that is of the force-locking type.
