Patent ID: 7614974

Claim:
A vehicle steering apparatus for a motor vehicle having a drive ( 101 , 102 ), which is coupled to a steering gear ( 122 ) via a disk cam mechanism ( 3 , 4 , 5 , 16 , 17 , 18 , 19 ) with an output shaft ( 2 ) with the longitudinal axis ( 8 ), wherein the disk cam mechanism comprises: at least one disk cam ( 3 , 4 ) with an undulating outer contour ( 33 , 34 ) disposed for eccentric rotation about the longitudinal axis ( 8 ); the at least one disk cam ( 3 , 4 ) having a circular central opening ( 30 a , 30 b ) in its center; the at least one disk cam ( 3 , 4 ) having at least two holes ( 31 ) lying on a concentric reference circle between the central opening ( 30 a , 30 b ) and the outer contour ( 33 , 34 ); a first carrier ( 16 ) which is arranged on a first shaft ( 1 , 1 ′) and the axis of which lies in the longitudinal axis ( 8 ), with driving pins ( 17 ) mounted to the first carrier ( 16 ) in parallel orientation to the longitudinal axis ( 8 ), which engage in holes ( 31 ) of the disk cam ( 3 , 4 ); a rotor shaft ( 6 ), which is supported in a carrier arrangement ( 11 , 11 a , 11 b ) and on the first shaft ( 1 , 1 ′) for coaxial rotation about the first shaft ( 1 , 1 ′) with the common longitudinal axis ( 8 ) and the latter is coupled to the drive ( 101 , 102 ) and carries at least one eccentric ( 5 a , 5 b ) with an eccentricity ( 22 ) in relation to the longitudinal axis ( 8 ), wherein each eccentric ( 5 , 5 b ) engages in the central opening ( 30 a , 30 b ) of an associated disk cam ( 3 , 4 ) to produce a laterally wobbling motion rotating about the longitudinal axis ( 8 ) of the respective disk cam ( 3 , 4 ); a second carrier ( 18 ) mounted to a second shaft ( 2 ), which is configured as an output shaft ( 2 ) rotatably supported in the carrier arrangement ( 11 , 11 a , 11 b ) for rotation about the longitudinal axis ( 8 ), wherein external pins ( 19 ) are mounted to the second carrier ( 18 ) radially spaced in parallel orientation to the longitudinal axis ( 8 ), on which the undulating contour ( 33 , 34 ) of the at least one disk cam ( 3 , 4 ) rolls off by the eccentric radially wobbling motion.
