Clamping device for a steering column
First Claim
1. A clamping device arranged on a steering column for positional fixing the steering column which is adjustable in length and/or inclination and is guided between mounting arms (4, 5) of a fixed bracket, said clamping device comprising a tie bolt (7) arranged at a right angle to the steering column and extends between said mounting arms (4, 5), one end of the tie bolt (7) being retained on one (5) of said mounting arms, while on an opposite end of the tie bolt (7) which projects beyond the other mounting arm (4), there is arranged between a thrust washer (11a, 11b) and the other mounting arm (4), a clamping washer (12a, 12b) comprising clamping ramps 13a, 13b) for supporting rolling elements (14a, 14b) which are guided in a retention disc (15a, 15b) and mounted for rotation on the tie bolt (7) while being adapted to be rotated by a manual hand lever (19), and, depending on a direction of rotation of the retention disc (15a, 15b), said mounting arms (4, 5) approach the steering column to effect clamping or move away from the steering column to release the steering column wherein the clamping ramps (13a, 13b) have a contour which changes continuously starting from a zero position up to a clamping position, the clamping device (1a, 1b) comprises a pot-shaped housing (2) which is rotationally fixed on the other mounting arm (4) by a bottom (3), and the housing (2), through which the tie bolt (7) is inserted, encloses the clamping washer and is clamped by the thrust washer (11a, 11b).

Abstract
A clamping device for a steering column (6) which is guided in fixed mounting arms (4, 5) and comprises a tie bolt (7) which is arranged at right angles to the steering column (6), the tie bolt (7) extends between the two mounting arms (4, 5), there being arranged on one end of the tie bolt (7), between a thrust washer (11a) and the mounting arm (4), a clamping washer (12a) comprising clamping ramps (13a) on which rolling elements (14a) are supported while being guided in a retention disc (15a) mounted for rotation on the tie bolt (7), the retention disc (15a) can be rotated by means of a hand lever (19), and, depending on a direction of rotation of the retention disc (15a), the mounting arms (4, 5) effect a clamping or a releasing of the steering column (6), characterized in that the clamping device (1a) comprises a pot-shaped housing (2) which bears against the mounting arm (4) by a bottom (3) and encloses all the clamping means, the housing (2) is closed at one end by a thrust washer (11a), while the clamping ramp (13a) of the clamping washer (12a) has a contour which changes continuously from a zero position up to a clamped position.
