Abstract
A device for coupling and uncoupling two parts which are movable relative to each other, particularly parts of the drives of vehicles, for instance for high-speed power vehicles, by means of a length-variable guide rod. On the tubular guide rod segment there is arranged a housing having a cylinder chamber in which the cylindrical part of the axially shiftable guide rod segment extends, this cylindrical part being provided with engaging portions for annular pistons which surround it. Two annular pistons are supports for a preloaded coil spring arranged therebetween, and upon pulling or compressive force, one of the spring-loaded annular pistons, depending upon the direction of force, is axially shifted against the preloaded coil spring by the corresponding engaging portion of the cylindrical rod part of the guide rod segment. At least one spring-loaded annular piston can be acted upon by pressure medium introduced into the cylinder chamber through an associated connection, and can be fixed in its acted-upon end position by means of a locking device located on the housing, with the guide rod segment being axially free, or shiftable at a lower force level, relative to the fixed annular piston by a given distance. The annular piston which is securely held by the locking device, after cancelling the positive connection and discharging the pressure medium from the cylinder chamber, is returned to its starting position by the pressure of the coil spring.
