Patent ID: 7694983

Claim:
A suspension system comprising: an upper link ( 20 ), the upper link ( 20 ) being mounted at an inner end to one of a vehicle body and a sub-frame by an inner spherical joint ( 22 ) and connected at an outer end to an upper end of a vertically extending hub carrier ( 16 ) by an outer spherical joint ( 24 ); a lower wishbone ( 12 ), the lower wishbone ( 12 ) being mounted at an inner end to the one of the vehicle body and the sub-frame for pivotal movement about a horizontal, longitudinally extending axis, by a pair of spaced compliant bushings ( 14 ) and connected at an outer end to a lower end of the hub carrier ( 16 ) by a lower spherical joint ( 26 ); an interlinking wishbone ( 30 ), the interlinking wishbone ( 30 ) being connected at a lower end to the lower wishbone ( 12 ), intermediate of the inner end and the outer end thereof, for pivotal movement, by one of a hinge joint and a revolute joint ( 32 ), the interim king wishbone ( 30 ) being connected at an upper end to the upper link ( 20 ) by an intermediate spherical joint ( 34 ), a center of rotation of the intermediate spherical joint ( 34 ) being offset from a line joining centers of rotation of the inner spherical joint ( 22 ) and the outer spherical joint ( 24 ); and the intermediate spherical joint ( 34 ) being located intermediate of the inner end and the outer end of the upper link ( 20 ), such that a ratio of distances between the inner spherical joint ( 22 ) and the intermediate spherical joint ( 34 ), and between the intermediate spherical joint ( 34 ) and the outer spherical joint ( 24 ) is substantially equal to a ratio of distances between the inner end of the lower wishbone ( 12 ) and the connection between the lower and interlinking wishbones ( 12 , 30 ) and between the connection between the lower and interlinking wishbones ( 12 , 30 ) and the outer end of the lower wishbone ( 12 ).
