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.

Device for coupling and uncoupling two parts movable relative to each

A device for measuring axial force in a shaft journalled or mounted with two roller bearings arranged side by side in a housing, such measuring occurring by means of wire strain gauges or the like. The inner ring of the roller bearing on the shaft side engages a shaft shoulder, and the end faces of the roller bodies of the roller body row facing the bearing cover are supported by the flangeless inner ring of the adjoining roller bearing against a flanged ring or angle ring which is disengageably arranged on the shaft. This device is especially intended for wheel-set shafts of rail vehicles during travelling operation. Those end faces of the roller bodies of the two roller body rows facing each other are supported on a central flanged ring which transfers force and is movable in the direction of force when force is applied. A gauge ring is located between the central flanged ring and those two end faces of the roller bearing rings located diametrically opposite each other, with a part of the gauge ring being arranged transverse to the shaft axis, being operatively connected with the central flanged ring, and being provided with wire strain gauges or the like. The gauge ring has a part remote from the central flanged ring. This part is positively connected, by means of pressure surfaces on both sides, with the diametrically opposed end faces of the roller bearing rings.
