ABSTRACT:
The invention relates to a locking device 4 for a freewheeling unit 1 of a non-directly driven axle of a motor vehicle driven by a directly driven axle. To lock the freewheeling unit 1 there is provided a first drive element 2 with a number of circumferentially distributed apertures 15 holding radially displaceable locking elements 16. The locking elements, for the purpose of establishing a non-rotating connection between the first drive element 2 and the second drive element 3, may partially enter recesses 17 of the second drive element 3 corresponding to the apertures. Radial displacement of the locking elements 16 is achieved by a spring loaded axially movable control element 10. Displacement of the control element 10 is achieved by radially outward displacement of centrifugal masses 20.
