Patent ID: 8205896

Claim:
An independent wheel suspension with a steering knuckle ( 1 ) which rotates about a rotational axis ( 5 ) and is supported on a spring carrier ( 16 ), which is connected with a frame of a vehicle via one of a damper ( 18 ) and an air spring ( 19 ) or a spring-damper-module ( 17 ), the steering knuckle ( 1 ) being connected with the spring carrier ( 16 ) via a kingpin ( 4 ), the independent wheel suspension comprises at least an upper transverse link ( 10 ), positioned at an upper end of the kingpin ( 4 ), and at least a lower transverse link ( 14 ), positioned at a lower end of the kingpin ( 4 ), the steering knuckle ( 1 ) and the upper and the lower transverse links ( 10 , 14 ) being pivotally positioned relative to the kingpin ( 4 ), and the spring carrier ( 16 ) being connected with the kingpin ( 4 ) in a rotationally fixed manner, the kingpin ( 4 ) being a connecting link for the spring carrier ( 16 ), the steering knuckle ( 1 ), and the upper and the lower transverse links ( 10 , 14 ), the kingpin ( 4 ) being a two-piece part comprising an upper part ( 20 ) and a lower part ( 21 ), at least an end of the upper part ( 20 ), adjacent the lower part ( 21 ), and an end of the lower part ( 21 ), adjacent the upper part ( 20 ), being enclosed within an axial cylindrical opening within the spring carrier ( 16 ) the end of the upper part ( 20 ), adjacent the lower part ( 21 ), having a first notch ( 27 ) and the end of the lower part ( 21 ), adjacent the upper part ( 20 ), having a second notch ( 27 ) with the first and second notches ( 27 ) being correspondingly shaped to engage with each when the upper part ( 20 ) and the lower part ( 21 ) are rotationally oriented with respect to each other to engage the first notch ( 27 ) with the second notch ( 27 ), the upper part ( 20 ) and the lower part ( 21 ) thereby being rotationally fixed with respect to each other and preventing axial twisting between the upper part ( 20 ) and the lower part ( 21 ), and the end of the upper part ( 20 ), adjacent the lower part ( 21 ), and the end of the lower part ( 21 ), adjacent the upper part ( 21 ), each having a circumferential groove ( 31 ) in an area not having a notch ( 27 ), and the spring carrier ( 16 ) including a first inwardly extending bar ( 32 ) engaging with the circumferential groove ( 31 ) in the end of the upper part ( 20 ), adjacent the lower part ( 21 ), and a second inwardly extending bar ( 32 ) engaging with the circumferential groove ( 31 ), the end of the lower part ( 21 ), adjacent the upper part ( 21 ), thereby axially fixing the upper part ( 20 ) and the lower part ( 21 ) with respect to each other and with respect to the spring carrier ( 16 ).
