INDEPENDENT SUSPENSION OF VEHICLE STEERABLE WHEELS Russian patent published in 2004 - IPC

FIELD: transport engineering; passenger cars. SUBSTANCE: proposed suspension contains steering knuckles hinge-coupled with car body by lower wishbone and longitudinal leaf spring coupled by ends with car body. Plane of spring leaves in place of its fastening to guide strut can be arranged square to longitudinal axis of strut. Spring can be hinge coupled by its central part either directly with wheel steering knuckle, or with damper housing made in form of Macpherson strut with rigid coupling with wheel steering knuckle, axes of hinge coupling lying on longitudinal axis of shock absorbing strut. This can be provided by making hole in central part of spring through which rod of shock absorbing strut passes, spring and shock absorbing strut being coupled by means of thrust bearing. Damper can coupled car body with lower wishbone of suspension. Hinge coupling of spring with steering knuckle or with damper housing can be made in form of ball support. Spring proper can be made single-leaf and/or of plastic materials. EFFECT: improved convenience of arrangement of suspension, prevention of transmission of forces from opposite wheels through spring, reduced longitudinal pliability of spring. 7 cl, 4 dwg
