Patent ID: 7357400

Claim:
A vehicle suspension device for a wheeled vehicle having wheels affixed to respective wheel carriers, each wheel suspended by first ends of respective suspension elements; the device comprising an intermediate support pivotably connected to the first ends of the suspension elements, and a camber mechanism for imparting to each wheel a degree of freedom of the camber relative to the suspension elements, the camber mechanism pivotably interconnecting the wheel carrier with the intermediate support, wherein the wheel carrier and the camber mechanism are movable relative to the intermediate support for changing the camber; the wheel linked to the suspension elements through the wheel support, the camber mechanism and the intermediate support so that the camber movement of each wheel relative to the intermediate support occurs for a mean position of the wheel about a position of 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 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 position of the instantaneous centre of rotation; Y is the abscissa of the position of the instantaneous centre of rotation; and R is the wheel radius.
