<p>Steering column assembly (12) with steering shafts axially movable but rotation prevented in relation to each other and disposed in a column jacket (8, 9) which column jacket comprises an outer jacket (8) and an inner jacket (9), the inner jacket (9) being axially slidably disposed in the outer jacket (8) which is provided with a first through aperture extending through the outer jacket (8) in which aperture a frictional plate (6) is located and provided with radially force transmitting means (2, 4, 5) arranged for applying a radial directed force on the frictional plate (6) resulting in that the frictional plate being pressed against the inner jacket (9) while manoeuvring the force transmitting means (2, 4, 5). The force transmitting means (2, 4, 5) comprises a first cam member (4) and a second cam member (5) each of which includes a number of inclined surfaces (510, 520, 410, 420) facing each other and in that one of the cam members (4) is rotationally fixed in relation to the frictional plate (6) while the other cam member (5) is rotationally mounted in relation to said plate (6) by a lever (17) in order to provide an axial displacement force between the two cam members (4, 5) by said surfaces which displacement force provides a radial motion acting upon the frictional plate (6) and directed towards the inner jacket (9).</p> |
