Suspension device for vehicle wheels

A vehicle suspension device for a wheeled vehicle having wheels suspended by suspension elements;

• the device comprising a camber mechanism for imparting to each wheel a degree of freedom of the camber relative to the suspension elements;
• the wheel linked to the suspension elements so that the camber movement of each wheel occurs from a mean position of the wheel about an instantaneous centre of rotation;
• the camber mechanism including a camber interconnection structure for transmitting the camber movements of a wheel to another wheel, wherein the instantaneous position of the instantaneous centre of rotation within the camber plane for a zero wheel camber satisfies the following condition:
• Z≦(0.75)Y−(0.12158)R
• wherein Z is the ordinate of the instantaneous position;
• Y is the abscissa of the instantaneous position;
• and R is the wheel radius.
