Shackle structure for suspension leaf spring

A shackle structure for supporting vehicle-rear-side end portions of a pair of left and right suspension leaf springs on a vehicle body via shackles, comprising:

• shackles including vehicle-body-side bushings supported on the vehicle body, and leaf-spring-side bushings supported on the leaf springs;
• wherein the vehicle-body-side bushings have rigidity center positions offset to further inside areas of a vehicle than rigidity center positions of the leaf-spring-side bushings,
• wherein the vehicle-body-side bushings and the leaf-spring-side bushings are split left and right in two halves, respectively;
• wherein for both the split bushings of the vehicle-body-side bushings divided in the two halves, the split bushing facing a vehicle inside has higher rigidity than that of the split bushing facing a vehicle outside, and
• wherein for both the split bushings of the leaf-spring-side bushings divided in the two halves, the split bushing facing the vehicle outside has higher rigidity than that of the split bushing facing the vehicle inside such that the rigidity center positions of both the vehicle-body-side bushings are offset to further inside areas of the vehicle than the rigidity center positions of both the leaf-spring-side bushings.

A shackle structure for supporting vehicle-front-side end portions of a pair of left and right suspension leaf springs on a vehicle body via shackles, comprising:

• shackles including vehicle-body-side bushings supported on the vehicle body, and leaf-spring-side bushings supported on the leaf springs;
• wherein the vehicle-body-side bushings have rigidity center positions offset to further outside areas of a vehicle than rigidity center positions of the leaf-spring-side bushings,
• wherein at least one of the vehicle-body-side bushings and the leaf-spring-side bushings are split left and right in two halves;
• wherein both the split bushings, divided in the two halves, are set to have rigidities different from each other to allow the rigidity center positions of the vehicle-body-side bushings to be offset to further outside areas of the vehicle than the rigidity center positions of the leaf-spring-side bushings.
